Comparative Genomic Analysis of Trichinella spiralis Reveals Potential Mechanisms of Adaptive Evolution

Figure 1

Gene Ontology (GO) term analysis for the positively selected genes of T. spiralis. The identified proteins were classified as GO terms in biological process, cellular component, and molecular function, according to their GO signatures. The left y-axis conveys the proportion of genes annotated in each GO term (gene number in each GO term divided by gene number in all GO terms). The right y-axis describes the gene number annotated in each GO term.
