SNP density and expression of effector genes and gene categories. Effectors found within repetitive regions were not significantly associated with SNP changes, although both effectors and secreted genes in any region of the genome were frequently up and downregulated in expression. Significance was calculated with Fisher’s exact tests in the GeneOverlap R package, and significance at < 0.05 is *, < 0.01 is **. Statistical comparisons were peformed between gene categories and high SNP density, low SNP density, zero SNPs, high expression, and low expression. Expression is represented as a log fold change of expression in a comparison of pre-parasitic and parasitic J2 nematodes
