Fig. 1From: Genomic introgression through interspecific hybridization counteracts genetic bottleneck during soybean domesticationPhylogenetic neighbor-joining tree of a panel of wild and cultivated soybeans. The tree was constructed based on genome-wide SNPs detected by genome resequencing using the MEGA program. Branches labeled in red and blue indicate G. soja and G. max (landrace), respectively. The codes for individual accessions and the fraction of introgressed fragments are shown in the out layers of the treeBack to article page
