Fig. 1: Scope and gene composition of specific groups.
From: Nutrient-driven genome evolution revealed by comparative genomics of chrysomonad flagellates
Genes were clustered to orthologous groups (OGs), whose composition is based on gene assignment with the KEGG top hierarchy level. The total amount of OGs is shown by gray (unannotated) and light blue (annotated) bars. a Single strains. b Combination of phototrophic (P), mixotrophic (M), and heterotrophic (H) strains. The pan genome contains every gene of the specific combination, whereas the core genome consists only of genes present in each strain of the group. See supp. Table S6 for values.
