| Title | A Novel Variation in the <i>FRIZZLE PANICLE</i> (<i>FZP</i>) Gene Promoter Improves grain number and Yield in Rice. | |
|
Abstract: Secondary branch number per panicle plays a crucial role in regulating grain number and yield in rice. Here, we report the positional cloning and functional characterization for <i>SECONDARY BRANCH NUMBER7</i> (<i>qSBN7</i>), a quantitative trait locus affecting secondary branch per panicle and grain number. Our research revealed that the causative variants of <i>qSBN7</i> are located in the distal promoter region of <i>FRIZZLE PANICLE</i> (<i>FZP</i>), a gene previously associated with the repression of axillary meristem development in rice spikelets. <i>qSBN7</i> is a novel allele of <i>FZP</i> that causes an ∼56% decrease in its transcriptional level, leading to increased secondary branch and grain number, and reduced grain length. Field evaluations showed that <i>qSBN7</i> increased grain yield by 10.9% in a <i>temperate japonica</i> variety, TN13, likely due to its positive effect on sink capacity. Our findings suggest that incorporation of <i>qSBN7</i> can increase yield potential and improve the breeding of elite rice varieties. |
