Genes showing presence and absence polymorphisms are linked to transposable elements. a The alignments view of short reads around SLP1 region. SLP1 was surrounded by multiple mapping reads and partial LTR retrotransposons. b Distribution of presence and absence polymorphisms within Oryza and Setaria isolates according to local TE density. Magnaporthe genes were ranked on the basis of ascending distance from 5’-end (y-axis) and 3’-end (x-axis) of genes to TEs. The number of genes corresponding to genes in each bin is shown as a heat map. 25, 50 and 75 % indicate first quartile, median and third quartile, respectively. The left and right panels are the distributions of all genes and genes showing presence/absence polymorphisms, respectively. c The bar plot shows the ratio of the number of genes showing presence and absence polymorphisms within Oryza and Setaria isolates to genes at each of category C1, C2, and C3. Statistical significance was evaluated by using exact Wilcoxon Mann–Whitney rank sum test (***: P < 0.001). Since the ratio in the C3 was very small, the value is not seen in the figure
