Summary of the different tests used to identify outlier contigs. In the distribution of Tajima’s D value of the cultivated species (a), the red line indicates the 1% threshold used to consider contigs as candidates. In the of reduction of nucleotide diversity π (b), the -log10 (πc/πw) for each contig is represented by one dot. The gray line corresponds to the 1% threshold used to consider contigs as candidates. In the comparison of FST between the cultivated and the two-wild species (c), each dot represents a contigs. The grey lines indicate the 1% threshold used to consider contigs as candidates. Finally, in the histogram of p-value (d), the peak of SNP close to zero indicates the presence of outliers. Here, the SNPs were considered as candidates using an FDR of 0.05
