The rice Os02g0701300 was reported as OsGRF4 in 2016 [1] by researchers from China.
Contents
Annotated Information
Gene Symbol
- Os02g0701300 <=> OsGRF4,GRF4
Function
- OsGRF4 controls grain shape, panicle length and seed shattering in rice.
Phenotypic analysis
- A unique OsGRF4 mutation, which occurs at the OsmiRNA396 target site of OsGRF4, seems to be associated with high levels of OsGRF4 expression, and results in phenotypic difference.
- Further research showed that OsGRF4 regulated two cytokinin dehydrogenase precursor genes (CKX5 and CKX1) resulting in increased cytokinin levels, which might affect the panicle traits.
Expression
- We compared the expression profiles of OsGRF4 in various organs of NILs by quantitative RT-PCR analysis with total RNA. The OsGRF4 transcript levels varied drastically among the tissues.
- OsGRF4 was preferentially expressed in developing panicles, and the highest levels of expression were found in panicles of 7 cm in length.
Subcellular localization
- To determine the sub-cellular localization of OsGRF4, the coding sequence of OsGRF4 was fused with yellow fluorescent protein (YFP). In contrast, Ghd7, which is a nuclear protein, was fused with cyan fluorescent protein (CFP). Both fluorescent proteins were individually driven by the constitutive 35S cauliflower mosaic virus promoter. The constructs were co-transfected into rice protoplasts of etiolated seedlings by polyethylene glycol. The result showed that OsGRF4 co-localized to the nucleus with Ghd7.
