Abstract excerpt
Flowering time of rice (Oryza sativa) plays important roles in regulating grain yield, quality, and adaptability. O. sativa GIGANTEAN (OsGI), heading date 1 (Hd1), and O. sativa flavin-binding, Kelch repeat, and F-box 1 (OsFKF1) are key factors controlling flowering time in rice. However, their relationships are not quite clear. In this study, we found that OsFKF1, an F-box domain-containing protein, physically...
