Rice grain yield consists of several key components, including tiller number, grain number per panicle (GNP), and grain weight. Among them, GNP is mainly determined by panicle branches and spikelet formation. In this study, we identified a gene affecting GNP and grain yield, <i>OsSPL9</i>, which encodes SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE (SPL) family proteins. The mutation of <i>OsSPL9</i> significantly reduced secondary branches and GNP. <i>OsSPL9</i> was highly expressed in the early devel ...[more]
