Annotated Information

Gene Symbol

• Os11g0152500 <=> RCN1,OsRCN1

Function

• TERMINAL FLOWER 1 (TFL1)/CENTRORADIALIS (CEN)-like genes play important roles in determining plant architecture, mainly by controlling the timing of phase transition.
• Rice may have a pathway that can respond to the overexpressed TFL1/CEN-like functions, and the molecular mechanisms controlling the phase transition of meristems are conserved between grass and dicot species, at least to some extent.

Phenotypic analysis

• In 35S::RCN1 and 35S::RCN2 transgenic rice plants, the delay of transition to the reproductive phase was observed. The transgenic rice plants exhibited a more branched, denser panicle morphology. Detailed observation of the panicle structure revealed that the phase change from the branch shoot to the ̄oral meristem state was also delayed, leading to the generation of higher-order panicle branches.
