Evolution of gene families, adaptive evolution in apicomplexan parasites, chromosomal distribution, and expression of EtAP2 and EtMyb gene families. Dynamics of gene family size in apicomplexa parasite genomes. The numbers below the branches indicate gene family expansions/contractions/stable, and the numbers above the branches show gene gains/losses/retention (a), Ka/Ks comparisons of the E. tenella genome with C. cayetanensis (b), Ka/Ks comparisons of the E. tenella genome with E. maxima (c), schematic representations of the chromosomal distribution of EtAP2 genes. The chromosome number is indicated at the upside of each chromosome (d), schematic representations of the chromosomal distribution of EtMyb genes, the chromosome number is indicated at the upside of each chromosome (e), the correlation between the gene expression patterns of 49 EtAP2 and 7 EtMyb genes (f), the scale in the figure represents the Log2(TPM values) after column normalization processing, where the depth of the color indicates the degree of correlation. The darker the color, the stronger the correlation, ranging from − 2 (completely negatively correlated) to 2 (completely positively correlated)
