Abstract excerpt
High yield and wide adaptation of rice are crucial for grain supply and food security. Here, we report a type II phosphatidylinositol 4-kinase, OsPI4Kγ7, which positively regulates rice yield and confers wide adaptation of rice. We show that OsPI4Kγ7 interacts with the transcription factor, OsLIC, and promotes its stability and nuclear translocation via phosphorylation, thereby increasing yield. Meanwhile, the...
