Expressions of genes showing PAPs. (a) The frequencies of expression (49%) and no expression (51%) for all PAP genes. (b) PAP genes were classified into five categories based on RPKM values: RPKM = 0, 1 ≤ RPKM < 5, 5 ≤ RPKM < 10, 10 ≤ RPKM< 50, 50 ≤ RPKM. The y-axis indicates the number of genes in each category. (c) Differences in gene expressions among individuals of A. digitifera. Rows are the 51 PAPs with complete matches between presence–absence patterns and expression patterns. Columns indicate the expression levels (RPKM) of three samples
