Fig. 6: Selection of SW14 during soybean domestication.
From: Natural allelic variation in SW14 determines seed weight and quality in soybean
Comparison of seed weight between different haplotypes of SW14 in wild soybean (a), landraces (b), and cultivars (c) grown in Guangzhou and Zhengzhou (112°42′E, 34°16′N) field. In the violin plot, the dashed lines indicate the median and dotted lines the interquartile range. d Haplotype frequency of SW14 in wild soybean, landraces, and cultivars. e Tajima’s D value and genetic variations (π) across the SW14 locus in 574 cultivars, 574 landraces, and 147 wild accessions. f, g Plot yield, seed oil content, and protein content of NIL-SW14H1 and NIL-SW14H3 in Guangzhou and Xiangyang (110°45′E, 31°14′N) field. The plot area is 5 m2. Values represent means ± SD (n = 3 biologically independent field plots). One-way ANOVA was used to generate the P values. Source data are provided as a Source Data file.
