Extended Data Fig. 8: DNA polymorphism analysis of Tan1, Tan2, Sh1, and Adh1.
From: Allelochemicals targeted to balance competing selections in African agroecosystems
a-h, A broad profile of nucleotide diversity (π, a-d) and fixation index (FST, e-h) with SNPs from a ±100-kb segment of each gene. i-j, The local FST profiles using SNPs from genes and their flanking regions between “wild and weedy – tannin cultivars” and “wild and weedy – non-tannin cultivars”. k-m, HKA tests using Adh1 as the neutral locus with the same accessions indicated in a. The red dashed vertical line in a-h indicates the starting position of each gene. The dashed grey line in e-h markers the level of FST = 0.2. The dashed grey line in k-m indicates the threshold of P < 0.05 (two-sided).
