OsCPD1 and OsCPD2 are functional brassinosteroid biosynthesis genes in rice

CONSTITUTIVE PHOTOMORPHOGENIC DWARF (CPD), member of the CYP90A family of cytochrome P450 (CYP450) monooxygenase, is an essential component of brassinosteroids (BRs) biosynthesis pathway. Compared with a single CPD/CYP90A1 in Arabidopsis thaliana, two highly homologous CPD genes, OsCPD1/CYP90A3 and OsCPD2/CYP90A4, are present in rice genome.There is still no genetic evidence so far about the requirement of OsCPD1 and OsCPD2 in rice BR biosynthesis.
