One MP tree from each of the five gene regions sequenced. CI, consistency index; RI, retention index, RC, rescaled consistency index. Numbers below branches represent bootstrap values based on 500 replicates. Only values ≥70% are shown. The 16 different A. flavus multilocus genotypes are represented by letters. Isolates used representing each multilocus genotype: A, 1–22; B, 1–9 (B1) and 5–1 (B2); C, 17–4; D, 1–26; E, 1–29; F, 3–2; G, 4–2; H, 12–4; I, 7–2; J, 7–3; K, 7–4; L, 11–1; M, 12–3; N, 13–4; O, 14–1; and P, 14–2. GenBank accession numbers are AF036768-787 (amdS12); AF036788-807 (benA56); AF036808-830 (omt12); AF036831-850 (pecA12); and AF036851-870 (trpC13).
