 *Figure 1 shows the gross morphology of the wild type and mutant plants. A mutant, B142, tagged with a T-DNA containing three CaMV 35S promoters showed a tall, GA-overproduction phenotype.The integrated T-DNAs, which contain three CaMV 35S promoters, are located upstream of the OsGA20ox1 open reading frame (ORF) in the B142 mutant genome. The ﬁnal stature of the B142 mutant reﬂects internode overgrowth and is approximately twice that of its wild-type parent<ref name="ref1" />.
 *Figure 2 shows a typical phenotype of a rice GA deﬁcient mutant at the young seedling stage. The GA-related mutants showed dwarﬁsm without the induction of additionally aberrantmorphology. The ﬁnal plant height of GA-deﬁcient mutants ranged widely between \5% and 90% of the wild-type plants. The leaf blades of the mutant plants became dark green, shorter, and wider than those of the wild-type plants<ref name="ref2" />.

 ===Expression===
 Semiquantitative reverse transcription (RT)-PCR analysis revealed that ''OsGA20ox1'' were expressed at different levels in various organs of wild-type rice(Fig. 3)<ref name="ref2" />. ''OsGA20ox1'' were simultaneously expressed in all vegetative organs of rice, and all ''OsGA20ox'' genes were expressed in the reproductive organs. This overlap expression pattern, accompanied with the feedback up-regulation of other GA biosynthetic enzymes by the homeostatic system<ref name="ref3" />, compensate the defect in OsGA20ox2 function in shoot elongation, and consequently the defect in ''OsGA20ox2/SD1'' induces suitable semidwarﬁsm of the rice height for useful breeding.
 ===Evolution===
 Figure 4 shows that phylogenetic analysis of 2ODDs (GA20ox, GA3ox, and GA2ox) revealed that the GA20ox proteins from dicot plants shared higher amino acid identity each other (49%–80% identities) and formed a single group. ''OsGA20ox2'' showed higher similarity (61% identity) to ''OsGA20ox4'' than the other OsGA20ox proteins, and ''OsGA20ox2'' and ''OsGA20ox4'' formed one subgroup (36%–48% identities with dicot proteins), whereas ''OsGA20ox1'' and ''OsGA20ox3'' were separately located from the ''OsGA20ox2/OsGA20ox4'' subgroup (39%–54% and 39%–49% identities with dicot proteins, respectively)<ref name="ref2" />.
 ===Knowledge Extension===
 The GAs form a large family of tetracyclic diterpenoid phytohormones that are involved in the regulation of various growth and developmental processes in higher plants. Bioactive GAs, such as GA1 and GA4,are synthesized from trans-geranylgeranyl diphosphate (GGDP) as shown in Figure 5<ref name="ref4" />.
