^aThe FFC species or daughter in which the recombinant region was detected.
^bThe position of the recombinant region according to the mt genome of each specific FFSC species, F mangiferae (KP742837), F. temperatum (KP742838), and F. circinatum (JX910419).
^cThe suggested origin of the recombinant region according to RDP, Geneconv, Bootscan and Maximum X² implemented in RDP version 3.44 (Martin et al. 2010). Unknown = the parent of this recombination event is not present within the dataset.
^dThe P-values for each of the recombination detection methods RDP, Geneconv, Bootscan and Maximum X² implemented in RDP version 3.44 (Martin et al. 2010). Only those events detected with all four methods are shown (see Supplementary Table S3 for the results for all individual tests). RDP identifies recombinant segments via pair-wise percentage identity values (Martin & Rybicki 2000), Geneconv detects recombinant segments as aligned pairs that are unusually long and sufficiently similar (Padidam et al. 1999), Bootscan identifies recombinant segments as high degree of bootstrap support for different phylogenies (Martin et al. 2005) and Maximum X² detects recombinant sections by comparing the number of segregating sites on both sides of the recombinant breakpoint (Smith 1992).
