Rice B2 and B3 RAFs play central roles in both ABA and osmotic stress signaling

ABSTRACT: Rice (Oryza sativa L.) is one of the most important crops worldwide. In the field, rice always faces low humidity, salinity, or drought in various growth stages, which largely limit seedling growth, tillering, filling, and yield of rice. Here, we generated B RAF high-order mutants by CRISPR/Cas9 mediated genome editing. By RNA-seq analysis, we found rice B2 and B3 RAFs play central roles in osmotic stress responses, the mannitol-induced expression genes are largely impaired. Our findings uncovered the central role of B2 and B3 RAFs in rice's osmotic stress responses and ABA signaling.
