Chromosomal distribution of F. graminearum TAPs. (A) The genome was divided into four blocks representing high (R ≥ 8) to low (R < 1) recombination rate (cM/27kb). Chromosomal locations of the B, C, P TAPs and D, O TAPs are shown above and below, respectively, of the recombination map. (B) The observed (Obs) and expected (Exp) TAP gene counts are shown per recombination block for each TAP class, compared with a uniform distribution of TAPs over F. graminearum gene positions (χ2-test; *: p < 0.05). (C) Graph of the percentage of clade-specific DNA-binding TAPs lying in regions of high recombination (R ≥ 3). The percentage of all DNA-binding TAPs (short dotted line), and of all genes (long dotted line), lying in regions with high recombination rate are indicated.
