Abstract excerpt
LEAFY COTYLEDON1 (LEC1), a NUCLEAR FACTOR-Y (NF-Y) family member, plays a critical role in embryogenesis and seed development in Arabidopsis. Previous studies have shown that rice OsNF-YB9 and OsNF-YB7 are homologous to Arabidopsis LEC1. However, the functions of LEC1-like genes in rice remain unclear. Here we report that OsNF-YB9 and OsNF-YB7 display sub-functionalization in rice. We demonstrate that OsNF-YB7 is...
