Species Oryza sativa (Rice) [ GR_tax:013681 ]
Accession GR:0060185
Gene Symbol D2
Gene Name DWARF EBISU 
Synonyms (6)

Chromosome No. 1
Gene Type CDS (Protein coding)
Has Phenotype yes
Description Short, stout stems; short, sinuate but board leaves; erect, compact panicles; small, round grains. Refer to dwf1. Compared to dwf1, has taller stem and near normal grains. The pleiotropic abnormal phenotype is similar to that of the rice brassinosteroid (BR)-insensitive mutant, d61. That dwarf phenotype can be rescued by exogenous brassinolide treatment. The accumulation profile of BR intermediates in the d2 (dwf2) mutants confirms that these plants are deficient in late BR biosynthesis. The results show that the D2 gene encoded a novel cytochrome P450 classified in CYP90D that is highly similar to the reported BR synthesis enzymes. Introduction of the wild D2 gene into d2-1 rescued the abnormal phenotype of the mutants. D2/CYP90D2 catalyzes the steps from 6-deoxoteasterone to 3-dehydro-6-deoxoteasterone and from teasterone to 3-dehydroteasterone in the late BR biosynthesis pathway.
