Presence-and-absence variation (PAV) of AsCEPs genes in Alternaria species. a Histogram showing the counts of AsCEPs genes that were found in one to twenty-nine (X-axis) Alternaria species, and heatmap showing the conservation of the most highly expressed AsCEPs genes. Yellow columns represent effector genes found in more than 26 or less than three Alternaria species. The number indicated on each column represents the count of AsCEP genes. Colors in heatmap represent the Log₂ (TPM + 1) values, and the numbers in grey boxes represent the number of Alternaria species in which each gene was found. b The number of AsCEPs genes that have homologs in other Alternaria species
