MiR396-OsGRF6 module controls rice inflorescence architecture

ABSTRACT: Developing strategies to increase rice productivity to meet global demand is one of the main challenges for breeders around the world. Here, we report a novel microRNA mediated process that increases rice grain yield in field trials. Expression of target mimicry of microRNA396 (MIM396) significantly increases rice yield by modulating the development of the auxiliary branches and spikelets through promoting the expression of Growth Regulation Factor 6 (OsGRF6). OsGRF6 coordinately induces the expression of several key factors involved in branch and spikelet development, auxin (IAA) biosynthesis, and auxin signaling pathway. Our results demonstrate that the miR396b-GRF6 module acts as a key player in shaping the inflorescence architecture of rice, which could be engineered to generate high-y
