Rice CENTRORADIALIS 2 regulates seed germination and salt tolerance via ABA-mediated pathway.

A FT/TFL1 subfamily gene, rice CENTRORADIALIS 2, also known as RCN1, regulates seed germination and increase salt tolerance via ABA-mediated pathway. The ABA synthesis and metabolism related genes were changed relative expression levels. Seed germination is a complex biological process that is affected by many factors.

Florigen repression complexes involving rice CENTRORADIALIS2 regulate grain size.

Grain size is one of the crucial factors determining grain yield. However, the genetic and molecular mechanisms of florigen repression complexes (FRCs) underlying grain size in rice (Oryza sativa L.) have not been reported.
