Description | OsDWARF4 is a homolog of A.taliana DWARF4, which encodes a cytochrome P450, CYP90B1. CTY90B1/DWARF4 catalyzes C-22 hydroxylation, the rate-limitinng step of brassinosteroid biosynthesis. OsDWARF4 is most abundant in leaf blades and roots, its expression is feedback regulated by brassinolide. osdwarf4-1 mutants show slightly dwarfism, and more erect leaves. osdwarf4-1/d11-4 double mutants exhibit severe dwarfing and malformed leaves with tortuous leaf blades as shown in BR-deficient brd1 mutant (GR:0080017). The erect leaf phenotype of osdwarf4-1 is associated with the enhanced grain yields under dense planting conditions, most of the increase in biomass and yield is directly attributable to an increase in panicle number in the mutants. |
