• Information
  • Symbol: OsDWARF4,CYP90B2
  • MSU: LOC_Os03g12660
  • RAPdb: Os03g0227700
• Publication
  • Erect leaves caused by brassinosteroid deficiency increase biomass production and grain yield in rice, 2006, Nat Biotechnol.
• Genbank accession number
  • AB206579
• Key message
  • Here we show that the erect leaf phenotype of a rice brassinosteroid-deficient mutant, osdwarf4-1, is associated with enhanced grain yields under conditions of dense planting, even without extra fertilizer
  • Molecular and biochemical studies reveal that two different cytochrome P450s, CYP90B2/OsDWARF4 and CYP724B1/D11, function redundantly in C-22 hydroxylation, the rate-limiting step of brassinosteroid biosynthesis
  • Therefore, despite the central role of brassinosteroids in plant growth and development, mutation of OsDWARF4 alone causes only limited defects in brassinosteroid biosynthesis and plant morphology
• Connection
  • D11~CPB1~CYP724B1~GNS4~PMM1, OsDWARF4~CYP90B2, Erect leaves caused by brassinosteroid deficiency increase biomass production and grain yield in rice, Molecular and biochemical studies reveal that two different cytochrome P450s, CYP90B2/OsDWARF4 and CYP724B1/D11, function redundantly in C-22 hydroxylation, the rate-limiting step of brassinosteroid biosynthesis
