Gene Symbol
- Os02g0531600 <=> OsRCN2,OsDP2,RCN2,DP2
Function
- Overexpression of RCN1 and RCN2 retarded the transition from vegetative to reproductive development in the SAM of rice
Phenotypic analysis
- A dense panicle mutant (dp2) derived from the Oryza sativa ssp. japonica cultivar Nipponbare through ethyl methane sulfonate mutagenesis was used in present study.
- The dp2 mutant did not exhibit a visibly abnormal phenotype during early vegetative growth stages compared to the wild type. After completely development, the panicle of the dp2 mutant became very dense in appearance, which was significantly different from the panicle of the wild type
- Compared to the wild type, the panicle of dp2 mutant exhibited more branches and denser grains. Further more, the number of spikelets per panicle, number of primary branches and secondary branches of dp2 mutant were significantly increased while the panicle length, and 1,000-grain weight were significantly decreased.
- The results from the genetic analysis indicated that the dense panicle phenotype was controlled by a single dominance nuclear gene.
