Natural Variation in the Promoter of GmSPL9d Affects Branch Number in Soybean.

ABSTRACT: The branch number is a crucial factor that influences density tolerance and is closely associated with the yield of soybean. However, its molecular regulation mechanisms remain poorly understood. This study cloned a candidate gene GmSPL9d for regulating the soybean branch number based on the rice OsSPL14 homologous gene. Meanwhile, the genetic diversity of the GmSPL9d was analyzed using 3599 resequencing data and identified 55 SNP/InDel variations, which were categorized into seven haplotypes. Evolutionary analysis classified these haplotypes into two groups: GmSPL9d ^H-I and GmSPL9d ^H-II. Soybean varieties carrying the GmSPL9d ^H-II haplotype exhibited a significantly lower branch number compared with those carrying
