| الوصف: | Flowering time is important for adaptation of soybean (Glycine max) to different environments. Here, we conducted a genome-wide association study of flowering time using a panel of 1490 cultivated soybean accessions. We identified three strong signals at the qFT02-2 locus (Chr02: 12037319–12238569), which were associated with flowering time in three environments: Gongzhuling, Mengcheng, and Nanchang. By analyzing linkage disequilibrium, gene expression patterns, gene annotation, and the diversity of variants, we identified an AP1 homolog as the candidate gene for the qFT02-2 locus, which we named GmAP1d. Only one nonsynonymous polymorphism existed among 1490 soybean accessions at position Chr02:12087053. Accessions carrying the Chr02:12087053-T allele flowered significantly earlier than those carrying the Chr02:12087053-A allele. Thus, we developed a cleaved amplified polymorphic sequence (CAPS) marker for the SNP at Chr02:12087053, which is suitable for marker-assisted breeding of flowering time. Knockout of GmAP1d in the ‘Williams 82’ background by gene editing promoted flowering under long-day conditions, confirming that GmAP1d is the causal gene for qFT02-2. An analysis of the region surrounding GmAP1d revealed that GmAP1d was artificially selected during the genetic improvement of soybean. Through stepwise selection, the proportion of modern cultivars carrying the Chr02:12087053-T allele has increased, and this allele has become nearly fixed (95%) in northern China. These findings provide a theoretical basis for better understanding the molecular regulatory mechanism of flowering time in soybean and a target gene that can be used for breeding modern soybean cultivars adapted to different latitudes. |
