Annotated Information
Gene Symbol
- Os04g0569100 <=> GL2-4 Roc4 Roc4(t)
Function
- Roc4 regulates flowering time mainly through Ghd7.
- Roc4 is an LD-preferential flowering enhancer that functions downstream of phytochromes and OsGI, but upstream of Ghd7.
Expression
- Expression of Rice outermost cell-specific gene 4 (Roc4), encoding a homeodomain Leu-zipper class IV family protein, was significantly increased.
Phenotypic analysis
- constitutive overexpression of Roc4 in‘Dongjin’ japonica rice, which carries active Ghd7, also caused LD-preferential early flowering, its overexpression in ‘Longjing27 rice, which is defective in functional Ghd7, did not produce the same result.
