a Gene orthology clusters among five sequenced species of nematodes, with 4,676 orthologous clusters being shared among all five species and 1,473 clusters being unique to S. carpocapsae. b The abundance of Pfam protein family domains in the C. elegans and S. carpocapsae genomes. The nine most enriched Pfam domains (biggest absolute difference) in S. carpocapsae relative to C. elegans are highlighted in red while the eleven most enriched Pfam domains in C. elegans relative to S. carpocapsae are highlighted in gray. c Select Pfam domains that are enriched in the sequenced steinernematids compared to other nematode species. d Protein neighbor-joining tree of the fatty acid- and retinol-binding proteins in nematodes. Monophyletic protein clades with at least one protein from each of the five Steinernema spp. are highlighted in blue. This figure illustrates both the abundance and diversity of FAR proteins among steinernematids. EPN entomopathogenic nematodes, FAR fatty acid- and retinol-binding proteins
