Factorial correspondence analysis (FCA) performed on the 4 races based on the 22 SNPs observed within putative effector sequences. Dudi.coa function (R software, ade4 package) was used to construct the CA factor map. The data table used for FCA was based on the absolute frequency observed for each CRN SNP (in red) for each race (100, 304, 703 and 710, in blue).
