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

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.

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.
