Diversity estimates of different gene families: (a) SNP-based nucleotide diversity (i.e., θπ), (b) proportion members affected by different types of large-effect SNPs, (c) mean pairwise protein distance for syntenic ortholog groups and (d) coefficient of variation (CV) of gene copy number in each ortholog group (i.e., an estimate of copy number variation) among accessions. Numbers in parenthesis reflect: (a) & (b) number of genes where ≥80% of the CDS regions were covered in at least 10 out of the 13 accessions; (c) number of syntenic ortholog groups where syntenic orthologs were present in ≥10 accessions (i.e., missing data in less than 3 accessions); (d) number of OrthoMCL-defined ortholog groups based entirely on protein sequence similarity
