Figure 5. Enrichment of GWAS results with signals of selection.
SNPs associated with both (a) silique length and (b) in planta concentration of Boron are strongly enriched in the extreme tail of scans testing for signatures of selection (e.g., −log10 rank statistic = 1 corresponds to the 10% tail). The sizes of the circles denote significance based on 1000 permutations (smallest circle shown corresponds to p=0.032 and the largest circle corresponds to p=0.001). GWAS SNPs were considered if their minor allele frequency was larger than 5% and when P < 1×10−4.
