Fig. 3. Genome scan for selection identifies the major aphid resistance allele at RMES1 originating in Ethiopia.

Fig. 3.

(A) Genome-wide scan for selection in the HBP using fixation index (FST) with the −log(FST P value) (y axis) plotted against position on the chromosome (x axis). (B) Detailed view (5 Mb) of top FST peak on chromosome 6 that colocalizes with the RMES1 locus. The ~130-kb region from 2,667,082 to 2,796,847 base pairs (bp) corresponding to the published RMES1 interval is denoted with the red bar. (C) Global allele distribution of the SNP that showed the highest FST value (S6_2995581), which colocalized with the RMES1 locus. Allelic state for georeferenced global germplasm is denoted with points. Allele frequencies in the U.S. (C = 151, T = 2, T/C = 1) and Haiti (C = 6, T = 287, T/C = 3) breeding germplasm, denoted in pie charts with area proportional to the number of accessions, show that the allele is almost fixed in Haitian breeding germplasm and rare in U.S. breeding germplasm.
