Gene Details:

• MSU gene ID: LOC_Os11g04710
• RAPdb gene ID: Os11g0143200
• Gene Symbol: OsCPD1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Moreover, overexpression of OsCPD1 and OsCPD2 led to a typical BR enhanced phenotype, with enlarged leaf angle and increased grain size.
• The overall growth and development of OsCPD1 and oscpd2 single knock-out mutants was indistinguishable from the wild-type, whereas, the OsCPD1 oscpd2 double mutant displayed multiple and obvious BR-related defects.
• OsCPD1 and OsCPD2 are functional brassinosteroid biosynthesis genes in rice.
• There is still no genetic evidence so far about the requirement of OsCPD1 and OsCPD2 in rice BR biosynthesis.
• Taken together, our results provide direct genetic evidence that OsCPD1 and OsCPD2 play essential and redundant roles in maintenance of plant architecture by modulating BR biosynthesis in rice.
• Cytological analyses further indicated the defective cell elongation in OsCPD1 oscpd2 double mutant.
