Malina:

The rice ''semidwarf-1 (sd1)'' is well known as the "green revolution gene" and controls the plant height of rice.

== Annotated Information ==
=== Function ===
[[File:Example.jpg|right|thumb|150px|''Semidwarf VS. normal-type rice plants at ripening (from reference <ref name="ref3" />).'']]

This gene is originally derived from the Chinese cultivar Dee-Geo-Woo-Gen(DGWG). It encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected <ref name="ref1" />. It is not surprising that a rice semidwarfing gene encodes GA20-ox since successful production of semidwarf plants using antisense or overexpressed GA20-ox genes has been reported in Arabidopsis, Solanum dulcamara, potato, and lettuce <ref name="ref3" />.

It is a key enzyme in the biosynthesis of gibberellin that catalyses the three steps GA53->GA44->GA19->GA20. Impaired GA 20-oxidase activity will cause elevated content of GA53, and reduced amount of G20 <ref name="ref1" /><ref name="ref2" />. However, there is slight difference between different strains. The extent of GA1 is lower in Doongara (semi-dwarf rice strain) when compared with Kyeema (tall), while there is no significant difference between Calrose76 (semi-dwarf rice strain) and Calrose (tall). Calrose76 has lower contents of GA44 and of GA19 than Calrose, while there is no significant difference between Doongara (semi-dwarf rice strain) and Kyeema (tall) <ref name="ref2" />.

'''GO assignment(s):''' GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
‘dee-geo-woo-gen’ (semi-dwarf rice strain): A 383-base-pair deletion from the genome (A 280-bp deletion within the coding region), which induces a frameshift that creates a stop codon in SD1, may be related with the semi-dwarf phenotype <ref name="ref1" /><ref name="ref2" />.

Calrose76 (semi-dwarf rice strain): The DNA sequence of Calrose76 is identical to Calrose (tall) except for a C to T transition at position 798 that resulted in a change of the predicted amino acid leucine (Leu-266) in Calrose to phenylalanine in Calrose76 <ref name="ref2" />.

It has been found that introgression of a chromosomal block containing the SD1 allele from tropical japonica is associated with a change in growth patterns in BHA1 (one weedy rice population) <ref name="ref7" />.

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower <ref name="ref1" />.

Among the DGWG-type sd-1 mutants, IR24 and Habataki have little transcript of this gene, while Milyang 23 expresses a normal or greater amount of truncated transcript. No significant difference is observed between Calrose and its single-nucleotide-substitution mutant Calrose 76 <ref name="ref3" />.

Analysis of the tissue- and stage-specificity of transcription of sd1 in Nipponbare revealed that this
gene was expressed within 48 hr after sowing, as well as in 10-day-old plants, 30-day-old leaves, and flowering panicles; no transcription is detected in 24-hr-old seedlings or in 14-day-old roots. Transcript accumulates predominantly in adult leaves <ref name="ref3" />.

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity). GA20ox-2 shows 47.8% identity to
GA20ox-1 in rice. There are at least three GA20-ox genes in Arabidopsis <ref name="ref1" /><ref name="ref2" />.

=== Knowledge Extension ===

[[File:Gibberellin SD1 RHT Signal.PNG|right|thumb|150px|''Gibberellin signalling pathway (from reference <ref name="ref4" />).'']]

Except ''sd1'', another ‘green revolution’ gene named ''Rht1'', which encodes a GA signal suppressor DELLA protein. The deletion in the N-terminal region of the native RHT1 constitutively suppresses GA signaling, consequently resulting in a dominant semi-dwarf phenotype <ref name="ref5" />. Both sd1 and Rht1 are associated with GA pathway, indicating the importance of GA in the regulation of developmental processes and making it a prime target for improving crop yield <ref name="ref4" />.

The wheat green-revolution gene Rht (for ‘reduced height’)<ref name="ref5" /> is a gain-of-function allele caused by a mutation in a transcription factor that is associated with the gibberellin signalling pathway. As wheat has a hexaploid genome, it does not contain recessive alleles such as sd1 in rice that might otherwise be used to produce a semi-dwarf strain of wheat. Although the genetic and biochemical functions of the rice SD1 and wheat RHT proteins are completely different (that is, recessive versus dominant, loss-of-function versus gain-offunction events, enzyme versus transcription factor, respectively), the products of both genes are linked with gibberellin malfunction <ref name="ref1" />.

In rice, ''Slr1'' gene encodes the DELLA protein. Three semi-dominant dwarf mutants (''Slr1-d1'', ''Slr1-d2'' and ''Slr1-d3'') associated with this gene have been identified, which were caused by gain-of-function mutations in the N-terminal region of SLR1. These three mutants are responsive to GA at a reduced rate, with later SLRl degradation, and showing reduced interaction activity with GID1 (GA receptor) comparing with wild type rice <ref name="ref6" />.

Malina: /* Mutation */

The rice ''semidwarf-1 (sd1)'' is well known as the "green revolution gene" and controls the plant height of rice.

== Annotated Information ==
=== Function ===
[[File:Example.jpg|right|thumb|150px|''Semidwarf VS. normal-type rice plants at ripening (from reference <ref name="ref3" />).'']]

This gene is originally derived from the Chinese cultivar Dee-Geo-Woo-Gen(DGWG). It encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected <ref name="ref1" />. It is not surprising that a rice semidwarfing gene encodes GA20-ox since successful production of semidwarf plants using antisense or overexpressed GA20-ox genes has been reported in Arabidopsis, Solanum dulcamara, potato, and lettuce <ref name="ref3" />.

It is a key enzyme in the biosynthesis of gibberellin that catalyses the three steps GA53->GA44->GA19->GA20. Impaired GA 20-oxidase activity will cause elevated content of GA53, and reduced amount of G20 <ref name="ref1" /><ref name="ref2" />. However, there is slight difference between different strains. The extent of GA1 is lower in Doongara (semi-dwarf rice strain) when compared with Kyeema (tall), while there is no significant difference between Calrose76 (semi-dwarf rice strain) and Calrose (tall). Calrose76 has lower contents of GA44 and of GA19 than Calrose, while there is no significant difference between Doongara (semi-dwarf rice strain) and Kyeema (tall) <ref name="ref2" />.

'''GO assignment(s):''' GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
‘dee-geo-woo-gen’ (semi-dwarf rice strain): A 383-base-pair deletion from the genome (A 280-bp deletion within the coding region), which induces a frameshift that creates a stop codon in SD1, may be related with the semi-dwarf phenotype <ref name="ref1" /><ref name="ref2" />.

Calrose76 (semi-dwarf rice strain): The DNA sequence of Calrose76 is identical to Calrose (tall) except for a C to T transition at position 798 that resulted in a change of the predicted amino acid leucine (Leu-266) in Calrose to phenylalanine in Calrose76 <ref name="ref2" />.

It has been found that introgression of a chromosomal block containing the SD1 allele from tropical japonica is associated with a change in growth patterns in BHA1 (one weedy rice population) <ref name="ref7" />.

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower <ref name="ref1" />.

Among the DGWG-type sd-1 mutants, IR24 and Habataki have little transcript of this gene, while Milyang 23 expresses a normal or greater amount of truncated transcript. No significant difference is observed between Calrose and its single-nucleotide-substitution mutant Calrose 76 <ref name="ref3" />.

Analysis of the tissue- and stage-specificity of transcription of sd1 in Nipponbare revealed that this
gene was expressed within 48 hr after sowing, as well as in 10-day-old plants, 30-day-old leaves, and flowering panicles; no transcription is detected in 24-hr-old seedlings or in 14-day-old roots. Transcript accumulates predominantly in adult leaves <ref name="ref3" />.

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity). GA20ox-2 shows 47.8% identity to
GA20ox-1 in rice. There are at least three GA20-ox genes in Arabidopsis <ref name="ref1" /><ref name="ref2" />.

=== Knowledge Extension ===

[[File:Gibberellin SD1 RHT Signal.PNG|right|thumb|150px|''Gibberellin signalling pathway (from reference <ref name="ref4" />).'']]

Except ''sd1'', another ‘green revolution’ gene named ''Rht1'', which encodes a GA signal suppressor DELLA protein. The deletion in the N-terminal region of the native RHT1 constitutively suppresses GA signaling, consequently resulting in a dominant semi-dwarf phenotype <ref name="ref5" />. Both sd1 and Rht1 are associated with GA pathway, indicating the importance of GA in the regulation of developmental processes and making it a prime target for improving crop yield <ref name="ref4" />.

The wheat green-revolution gene Rht (for ‘reduced height’)<ref name="ref5" /> is a gain-of-function allele caused by a mutation in a transcription factor that is associated with the gibberellin signalling pathway. As wheat has a hexaploid genome, it does not contain recessive alleles such as sd1 in rice that might otherwise be used to produce a semi-dwarf strain of wheat. Although the genetic and biochemical functions of the rice SD1 and wheat RHT proteins are completely different (that is, recessive versus dominant, loss-of-function versus gain-offunction events, enzyme versus transcription factor, respectively), the products of both genes are linked with gibberellin malfunction <ref name="ref1" />.

In rice, ''Slr1'' gene encodes the DELLA protein. Three semi-dominant dwarf mutants (''Slr1-d1'', ''Slr1-d2'' and ''Slr1-d3'') associated with this gene have been identified, which were caused by gain-of-function mutations in the N-terminal region of SLR1. These three mutants are responsive to GA at a reduced rate, with later SLRl degradation, and showing reduced interaction activity with GID1 (GA receptor) comparing with wild type rice <ref name="ref6" />.

Malina: /* Function */

The rice ''semidwarf-1 (sd1)'' is well known as the "green revolution gene" and controls the plant height of rice.

== Annotated Information ==
=== Function ===
[[File:Example.jpg|right|thumb|150px|''Semidwarf VS. normal-type rice plants at ripening (from reference <ref name="ref3" />).'']]

This gene is originally derived from the Chinese cultivar Dee-Geo-Woo-Gen(DGWG). It encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected <ref name="ref1" />. It is not surprising that a rice semidwarfing gene encodes GA20-ox since successful production of semidwarf plants using antisense or overexpressed GA20-ox genes has been reported in Arabidopsis, Solanum dulcamara, potato, and lettuce <ref name="ref3" />.

It is a key enzyme in the biosynthesis of gibberellin that catalyses the three steps GA53->GA44->GA19->GA20. Impaired GA 20-oxidase activity will cause elevated content of GA53, and reduced amount of G20 <ref name="ref1" />.<ref name="ref2" />. However, there is slight difference between different strains. The extent of GA1 is lower in Doongara (semi-dwarf rice strain) when compared with Kyeema (tall), while there is no significant difference between Calrose76 (semi-dwarf rice strain) and Calrose (tall). Calrose76 has lower contents of GA44 and of GA19 than Calrose, while there is no significant difference between Doongara (semi-dwarf rice strain) and Kyeema (tall) <ref name="ref2" />.

'''GO asignment(s):''' GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
‘dee-geo-woo-gen’ (semi-dwarf rice strain): A 383-base-pair deletion from the genome (A 280-bp deletion within the coding region), which induces a frameshift that creates a stop codon in SD1, may be related with the semi-dwarf phenotype <ref name="ref1" /><ref name="ref2" />.

Calrose76 (semi-dwarf rice strain): The DNA sequence of Calrose76 is identical to Calrose (tall) except for a C to T transition at position 798 that resulted in a change of the predicted amino acid leucine (Leu-266) in Calrose to phenylalanine in Calrose76 <ref name="ref2" />.

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower <ref name="ref1" />.

Among the DGWG-type sd-1 mutants, IR24 and Habataki have little transcript of this gene, while Milyang 23 expresses a normal or greater amount of truncated transcript. No significant difference is observed between Calrose and its single-nucleotide-substitution mutant Calrose 76 <ref name="ref3" />.

Analysis of the tissue- and stage-specificity of transcription of sd1 in Nipponbare revealed that this
gene was expressed within 48 hr after sowing, as well as in 10-day-old plants, 30-day-old leaves, and flowering panicles; no transcription is detected in 24-hr-old seedlings or in 14-day-old roots. Transcript accumulates predominantly in adult leaves <ref name="ref3" />.

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity). GA20ox-2 shows 47.8% identity to
GA20ox-1 in rice. There are at least three GA20-ox genes in Arabidopsis <ref name="ref1" /><ref name="ref2" />.

=== Knowledge Extension ===
The wheat green-revolution gene Rht (for ‘reduced height’)<ref name="ref4" /> is a gain-of-function allele caused by a mutation in a transcription factor that is associated with the gibberellin signalling pathway. As wheat has a hexaploid genome, it does not contain recessive alleles such as sd1 in rice that might otherwise be used to produce a semi-dwarf strain of wheat. Although the genetic and biochemical functions of the rice SD1 and wheat RHT proteins are completely different (that is, recessive versus dominant, loss-of-function versus gain-offunction events, enzyme versus transcription factor, respectively), the products of both genes are linked with gibberellin malfunction <ref name="ref1" />.

The rice ''semidwarf-1 (sd1)'' is well known as the "green revolution gene" and controls the plant height of rice.

== Annotated Information ==
=== Function ===
This gene is originally derived from the chinese cultivar Dee-Geo-Woo-Gen(DGWG). It encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected <ref name="ref1" />. It is not surprising that a rice semidwarfing gene encodes GA20-ox since successful production of semidwarf plants using antisense or overexpressed GA20-ox genes has been reported in Arabidopsis, Solanum dulcamara, potato, and lettuce [3].

It is a key enzyme in the biosynthesis of gibberellin that catalyses the three steps GA53->GA44->GA19->GA20. Impaired GA 20-oxidase activity will cause elevated content of GA53, and reduced amount of G20 <ref name="ref1" />.<ref name="ref2" />. However, there is slight difference between different strains. The extent of GA1 is lower in Doongara (semi-dwarf rice strain) when compared with Kyeema (tall), while there is no significant difference between Calrose76 (semi-dwarf rice strain) and Calrose (tall). Calrose76 has lower contents of GA44 and of GA19 than Calrose, while there is no significant difference between Doongara (semi-dwarf rice strain) and Kyeema (tall) <ref name="ref2" />.

GO asignment(s): GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
‘dee-geo-woo-gen’ (semi-dwarf rice strain): A 383-base-pair deletion from the genome (A 280-bp deletion within the coding region), which induces a frameshift that creates a stop codon in SD1, may be related with the semi-dwarf phenotype <ref name="ref1" /><ref name="ref2" />[3].

Calrose76 (semi-dwarf rice strain): The DNA sequence of Calrose76 is identical to Calrose (tall) except for a C to T transition at position 798 that resulted in a change of the predicted amino acid leucine (Leu-266) in Calrose to phenylalanine in Calrose76 <ref name="ref2" />.

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower <ref name="ref1" />.

Among the DGWG-type sd-1 mutants, IR24 and Habataki have little transcript of this gene, while Milyang 23 expresses a normal or greater amount of truncated transcript. No significant difference is observed between Calrose and its single-nucleotide-substitution mutant Calrose 76 [3].

Analysis of the tissue- and stage-specificity of transcription of sd1 in Nipponbare revealed that this
gene was expressed within 48 hr after sowing, as well as in 10-day-old plants, 30-day-old leaves, and flowering panicles; no transcription is detected in 24-hr-old seedlings or in 14-day-old roots. Transcript accumulates
predominantly in adult leaves [3].

Primers for gene amplication: forward primer, 5'-CAACTCACTCCCGCTCAACACAGC-3', and reverse primer, 5'-TTTGAAATGCAATGTCGTCCACC-3' were used to amplify exon 1; forward primer, 5'-GCGCCAATGGGGTAATTAAAACG-3' and reverse primer, 5'-GGCATTCCATTGTTTGTGATTGG-3' were used for exon 2; forward primer, 5'-GTTTGTCCTTGTCGCGTTGCTCAG-3' and reverse primer, 5'-TCTGTTCGTTCCGTTTCGTTCCG-3' were used for exon 3 <ref name="ref2" />.

Primers for RT-PCR: forward primer 5'-CAACTCACTCCCGCTCAACACAGC- 3' located 22-bp upstream from the translation start, and a reverse primer 5'-GTTCGTTCCGTTTCGGTTCCG- 3' eight-bp downstream from the TGA stop codon <ref name="ref2" />.

Primers for RT-PCR: forward primer: 5'-AGCTGGACATGCCCGTGGTC-3' and reverse primer : 5'-TTGAGCTGCTGTCCGCGAAG-3' [3].

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity). GA20ox-2 shows 47.8% identity to
GA20ox-1 in rice. There are at least three GA20-ox genes in Arabidopsis <ref name="ref1" />.<ref name="ref2" />.

=== Knowledge Extension ===
The wheat green-revolution gene Rht (for ‘reduced height’)[4] is a gain-of-function allele caused by a mutation in a transcription factor that is associated with the gibberellin signalling pathway. As wheat has a hexaploid genome, it does not contain recessive alleles such as sd1 in rice that might otherwise be used to produce a semi-dwarf strain of wheat. Although the genetic and biochemical functions of the rice SD1 and wheat RHT proteins are completely different (that is, recessive versus dominant, loss-of-function versus gain-offunction events, enzyme versus transcription factor, respectively), the products of both genes are linked with gibberellin malfunction [1].

This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity). GA20ox-2 shows 47.8% identity to
GA20ox-1 in rice. There are at least three GA20-ox genes in Arabidopsis <ref name="ref1" />.<ref name="ref2" />.

=== Knowledge Extension ===
The wheat green-revolution gene Rht (for ‘reduced height’)[4] is a gain-of-function allele caused by a mutation in a transcription factor that is associated with the gibberellin signalling pathway. As wheat has a hexaploid genome, it does not contain recessive alleles such as sd1 in rice that might otherwise be used to produce a semi-dwarf strain of wheat. Although the genetic and biochemical functions of the rice SD1 and wheat RHT proteins are completely different (that is, recessive versus dominant, loss-of-function versus gain-offunction events, enzyme versus transcription factor, respectively), the products of both genes are linked with gibberellin malfunction [1].

Malina:

The rice ''semidwarf-1 (sd1)'' is well known as the "green revolution gene" and controls the plant height of rice.

== Annotated Information ==
=== Function ===
This gene is originally derived from the chinese cultivar Dee-Geo-Woo-Gen(DGWG). It encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected <ref name="ref1" />. It is not surprising that a rice semidwarfing gene encodes GA20-ox since successful production of semidwarf plants using antisense or overexpressed GA20-ox genes has been reported in Arabidopsis, Solanum dulcamara, potato, and lettuce.

It is a key enzyme in the biosynthesis of gibberellin that catalyses the three steps GA53->GA44->GA19->GA20. Impaired GA 20-oxidase activity will cause elevated content of GA53, and reduced amount of G20 <ref name="ref1" />.<ref name="ref2" />. However, there is slight difference between different strains. The extent of GA1 is lower in Doongara (semi-dwarf rice strain) when compared with Kyeema (tall), while there is no significant difference between Calrose76 (semi-dwarf rice strain) and Calrose (tall). Calrose76 has lower contents of GA44 and of GA19 than Calrose, while there is no significant difference between Doongara (semi-dwarf rice strain) and Kyeema (tall) <ref name="ref2" />.

GO asignment(s): GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
‘dee-geo-woo-gen’ (semi-dwarf rice strain): A 383-base-pair deletion from the genome (A 280-bp deletion within the coding region), which induces a frameshift that creates a stop codon in SD1, may be related with the semi-dwarf phenotype <ref name="ref1" /><ref name="ref2" />[3].

Calrose76 (semi-dwarf rice strain): The DNA sequence of Calrose76 is identical to Calrose (tall) except for a C to T transition at position 798 that resulted in a change of the predicted amino acid leucine (Leu-266) in Calrose to phenylalanine in Calrose76 <ref name="ref2" />.

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower <ref name="ref1" />.

Among the DGWG-type sd-1 mutants, IR24 and Habataki have little transcript of this gene, while Milyang 23 expresses a normal or greater amount of truncated transcript. No significant difference is observed between Calrose and its single-nucleotide-substitution mutant Calrose 76 [3].

Analysis of the tissue- and stage-specificity of transcription of sd1 in Nipponbare revealed that this
gene was expressed within 48 hr after sowing, as well as in 10-day-old plants, 30-day-old leaves, and flowering panicles; no transcription is detected in 24-hr-old seedlings or in 14-day-old roots. Transcript accumulates
predominantly in adult leaves [3].

Primers for gene amplication: forward primer, 5'-CAACTCACTCCCGCTCAACACAGC-3', and reverse primer, 5'-TTTGAAATGCAATGTCGTCCACC-3' were used to amplify exon 1; forward primer, 5'-GCGCCAATGGGGTAATTAAAACG-3' and reverse primer, 5'-GGCATTCCATTGTTTGTGATTGG-3' were used for exon 2; forward primer, 5'-GTTTGTCCTTGTCGCGTTGCTCAG-3' and reverse primer, 5'-TCTGTTCGTTCCGTTTCGTTCCG-3' were used for exon 3 <ref name="ref2" />.

Primers for RT-PCR: forward primer 5'-CAACTCACTCCCGCTCAACACAGC- 3' located 22-bp upstream from the translation start, and a reverse primer 5'-GTTCGTTCCGTTTCGGTTCCG- 3' eight-bp downstream from the TGA stop codon <ref name="ref2" />.

Primers for RT-PCR: forward primer: 5'-AGCTGGACATGCCCGTGGTC-3' and reverse primer : 5'-TTGAGCTGCTGTCCGCGAAG-3' [3].

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity). GA20ox-2 shows 47.8% identity to
GA20ox-1 in rice. There are at least three GA20-ox genes in Arabidopsis <ref name="ref1" />.<ref name="ref2" />.

Malina:

The rice ''semidwarf-1 (sd1)'' is well known as the "green revolution gene" and controls the plant height of rice.

== Annotated Information ==
=== Function ===
This gene is originally derived from the chinese cultivar Dee-Geo-Woo-Gen(DGWG). It encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected <ref name="ref1" />. It is not surprising that a rice semidwarfing gene encodes GA20-ox since successful production of semidwarf plants using antisense or overexpressed GA20-ox genes has been reported in Arabidopsis, Solanum dulcamara, potato, and lettuce.

It is a key enzyme in the biosynthesis of gibberellin that catalyses the three steps GA53->GA44->GA19->GA20. Impaired GA 20-oxidase activity will cause elevated content of GA53, and reduced amount of G20 <ref name="ref1" />.<ref name="ref2" />. However, there is slight difference between different strains. The extent of GA1 is lower in Doongara (semi-dwarf rice strain) when compared with Kyeema (tall), while there is no significant difference between Calrose76 (semi-dwarf rice strain) and Calrose (tall). Calrose76 has lower contents of GA44 and of GA19 than Calrose, while there is no significant difference between Doongara (semi-dwarf rice strain) and Kyeema (tall) <ref name="ref2" />.

GO asignment(s): GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
‘dee-geo-woo-gen’ (semi-dwarf rice strain) and IR8 (semi-dwarf rice strain): A 383-base-pair deletion, which induces a frameshift that creates a stop codon in SD1 may be related with the semi-dwarf phenotype <ref name="ref1" />.

Doongara (semi-dwarf rice strain): A 280-bp deletion within the coding region, which spans parts of exon 1 and exon 2, is predicted to result in a truncated, nonfunctional polypeptide containing the first 99 amino acid residues of the GA 2-oxidase, followed by an additional 3 amino acids that are in the wrong reading frame before a termination codon <ref name="ref2" />.

Calrose76 (semi-dwarf rice strain): The DNA sequence of Calrose76 is identical to Calrose (tall) except for a C to T transition at position 798 that resulted in a change of the predicted amino acid leucine (Leu-266) in Calrose to phenylalanine in Calrose76 <ref name="ref2" />.

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower <ref name="ref1" />.

Primers for DNA amplication: forward primer, 5'-CAACTCACTCCCGCTCAACACAGC-3', and reverse primer, 5'-TTTGAAATGCAATGTCGTCCACC-3' were used to amplify exon 1; forward primer, 5'-GCGCCAATGGGGTAATTAAAACG-3' and reverse primer, 5'-GGCATTCCATTGTTTGTGATTGG-3' were used for exon 2; forward primer, 5'-GTTTGTCCTTGTCGCGTTGCTCAG-3' and reverse primer, 5'-TCTGTTCGTTCCGTTTCGTTCCG-3' were used for exon 3 <ref name="ref2" />.

Primers for RT-PCR: forward primer 5'-CAACTCACTCCCGCTCAACACAGC- 3' located 22-bp upstream from the translation start, and a reverse primer 5'-GTTCGTTCCGTTTCGGTTCCG- 3' eight-bp downstream from the TGA stop codon <ref name="ref2" />.

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity). GA20ox-2 shows 47.8% identity to
GA20ox-1 in rice. There are at least three GA20-ox genes in Arabidopsis <ref name="ref1" />.<ref name="ref2" />.

Malina:

The rice ''semidwarf-1 (sd1)'' is well known as the "green revolution gene" and controls the plant height of rice.

== Annotated Information ==
=== Function ===
This gene is originally derived from the chinese cultivar Dee-Geo-Woo-Gen(DGWG). It encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected [1]. It is not surprising that a rice semidwarfing gene encodes GA20-ox since successful production of semidwarf plants using antisense or overexpressed GA20-ox genes has been reported in Arabidopsis, Solanum dulcamara, potato, and lettuce.

It is a key enzyme in the biosynthesis of gibberellin that catalyses the three steps GA53->GA44->GA19->GA20. Impaired GA 20-oxidase activity will cause elevated content of GA53, and reduced amount of G20 [1][2]. However, there is slight difference between different strains. The extent of GA1 is lower in Doongara (semi-dwarf rice strain) when compared with Kyeema (tall), while there is no significant difference between Calrose76 (semi-dwarf rice strain) and Calrose (tall). Calrose76 has lower contents of GA44 and of GA19 than Calrose, while there is no significant difference between Doongara (semi-dwarf rice strain) when compared with Kyeema (tall) [2].

GO asignment(s): GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
‘dee-geo-woo-gen’ (semi-dwarf rice strain) and IR8 (semi-dwarf rice strain): A 383-base-pair deletion, which induces a frameshift that creates a stop codon in SD1 may be related with the semi-dwarf phenotype [1].

Doongara (semi-dwarf rice strain): A 280-bp deletion within the coding region, which spans parts of exon 1 and exon 2, is predicted to result in a truncated, nonfunctional polypeptide containing the first 99 amino acid residues of the GA 2-oxidase, followed by an additional 3 amino acids that are in the wrong reading frame before a termination codon [2].

Calrose76 (semi-dwarf rice strain): The DNA sequence of Calrose76 is identical to Calrose (tall) except for a C to T transition at position 798 that resulted in a change of the predicted amino acid leucine (Leu-266) in Calrose to phenylalanine in Calrose76 [2].

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower [1].

Primers for DNA amplication: forward primer, 5'-CAACTCACTCCCGCTCAACACAGC-3', and reverse primer, 5'-TTTGAAATGCAATGTCGTCCACC-3' were used to amplify exon 1; forward primer, 5'-GCGCCAATGGGGTAATTAAAACG-3' and reverse primer, 5'-GGCATTCCATTGTTTGTGATTGG-3' were used for exon 2; forward primer, 5'-GTTTGTCCTTGTCGCGTTGCTCAG-3' and reverse primer, 5'-TCTGTTCGTTCCGTTTCGTTCCG-3' were used for exon 3 [2].

Primers for RT-PCR: forward primer 5'-CAACTCACTCCCGCTCAACACAGC- 3' located 22-bp upstream from the translation start, and a reverse primer 5'-GTTCGTTCCGTTTCGGTTCCG- 3' eight-bp downstream from the TGA stop codon [2].

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity). GA20ox-2 shows 47.8% identity to
GA20ox-1 in rice. There are at least three GA20-ox genes in Arabidopsis [1][2].

Malina: /* Structured Information */

The rice ''semidwarf-1 (sd1)'' is well known as the "green revolution gene" and controls the plant height of rice.

== Annotated Information ==
=== Function ===
This gene is originally derived from the chinese cultivar Dee-Geo-Woo-Gen(DGWG. It encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected. It is not surprising that a rice semidwarfing gene encodes GA20-ox since successful production of semidwarf plants using antisense or overexpressed GA20-ox genes has been reported in Arabidopsis, Solanum dulcamara, potato, and lettuce.

GO asignment(s): GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
A 383-base-pair deletion, which induces a frameshift that creates a stop codon in SD1 may be related with the semi-dwarf phenotype of rice.

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower.

Primers for DNA amplication: forward primer, 5'-CAACTCACTCCCGCTCAACACAGC-3', and reverse primer, 5'-TTTGAAATGCAATGTCGTCCACC-3' were used to amplify exon 1; forward primer, 5'-GCGCCAATGGGGTAATTAAAACG-3' and reverse primer, 5'-GGCATTCCATTGTTTGTGATTGG-3' were used for exon 2; forward primer, 5'-GTTTGTCCTTGTCGCGTTGCTCAG-3' and reverse primer, 5'-TCTGTTCGTTCCGTTTCGTTCCG-3' were used for exon 3.

Primers for RT-PCR: forward primer 5'-CAACTCACTCCCGCTCAACACAGC- 3' located 22-bp upstream from the translation start, and a reverse primer 5'-GTTCGTTCCGTTTCGGTTCCG- 3' eight-bp downstream from the TGA stop codon.

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity). There are at least three GA20-ox genes in Arabidopsis.

Malina:

''sd1'' controls the plant height of rice.

== Annotated Information ==
=== Function ===
This gene encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected.

GO asignment(s): GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
A 383-base-pair deletion, which induces a frameshift that creates a stop codon in SD1 may be related with the semi-dwarf phenotype of rice.

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower.

Primers for DNA amplication: forward primer, 5'-CAACTCACTCCCGCTCAACACAGC-3', and reverse primer, 5'-TTTGAAATGCAATGTCGTCCACC-3' were used to amplify exon 1; forward primer, 5'-GCGCCAATGGGGTAATTAAAACG-3' and reverse primer, 5'-GGCATTCCATTGTTTGTGATTGG-3' were used for exon 2; forward primer, 5'-GTTTGTCCTTGTCGCGTTGCTCAG-3' and reverse primer, 5'-TCTGTTCGTTCCGTTTCGTTCCG-3' were used for exon 3.

Primers for RT-PCR: forward primer 5'-CAACTCACTCCCGCTCAACACAGC- 3' located 22-bp upstream from the translation start, and a reverse primer 5'-GTTCGTTCCGTTTCGGTTCCG- 3' eight-bp downstream from the TGA stop codon.

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity).

Malina: /* Evolution */

''sd1'' is XXX, controls the plant height of rice.

== Annotated Information ==
=== Function ===
This gene encodes an oxidase enzyme involved in the biosynthesis of gibberellin, which is a plant growth hormone. The rice genome carries at least two GA20ox genes (GA20ox-1 and GA20ox-2).SD1 corresponds to GA20ox-2. Mutation of SD1 will cause a semi-dwarf phenotype of rice without seed yield being affected.

GO asignment(s): GO:0005506, GO:0016216, GO:0017000

=== Mutation ===
A 383-base-pair deletion, which induces a frameshift that creates a stop codon in SD1 may be related with the semi-dwarf phenotype of rice.

=== Expression ===
This gene is strongly expressed in the leaf blade, stem and unopened flower, whereas GA20ox-1 is predominantly expressed in the unopened flower.

=== Evolution ===
This gene is conserved in ''Arabidopsis'' (47% identity) and pea(50% identity).
