A. Geographic origin ofAlternaria alternatasampled from citrus in 12 countries (small black circles). The numbers of isolates sampled from each country are in parentheses. The pie chart for each country represents the number of endoPG haplotypes with each color denoting a different endoPG haplotype [(Hap1 (Fuschia), Hap2 (orange), Hap3 (blue), Hap4 (dark blue), Hap5 (red), Hap6 (maroon), Hap7 (yellow), Hap8 (green), Hap9 (pink), Hap10 (light pink), Hap11 (brown), Hap12 (purple), and Hap13 (light yellow)]. B. An endo-polygalacturonase (endoPG) phylogeny estimated among a worldwide sample of citrus brown spot isolates using Bayesian inference with A. tomato as an outgroup. Three phylogenetic lineages identified correspond to Clades 1, 2, and 3 of Peever et al. [35]. Node support is given as posterior probabilities and bootstrap values based on Bayesian and likelihood analyses.
