Functional analysis of the E. hormaechei complex pan-genome fractions. A Venn diagram depicting the orthogroups core to all three species, shared by two of the species and unique to a single species. Numbers in red denote those proteins conserved among all compared taxa in a pan-genome fraction. B Bar chart showing proportions of proteins per COG category. Bars shaded in full are those showing > two-fold representation in the accessory pan-genome fractions compared to the core fractions and bars shaded with downward hashes depict those COG functions with > two-fold representation in the core pan-genome fraction compared to the accessory fractions. The letters in the legend represent the codes for each functional category as per the COG database [21]: C: Energy production and conversion, D: Cell cycle control, cell division, chromosome partitioning, E: Amino acid transport and metabolism, F: Nucleotide transport and metabolism, G: Carbohydrate transport and metabolism, H: Coenzyme transport and metabolism, I: Lipid transport and metabolism, J: Translation, ribosomal structure and biogenesis, K: Transcription, L: Replication, recombination and repair, M: Cell wall/membrane/envelope biogenesis, N: Cell motility, O: Posttranslational modification, protein turnover, chaperones, P: Inorganic ion transport and metabolism, Q: Secondary metabolite biosynthesis, transport and catabolism, T: Signal transduction mechanisms, U: Intracellular trafficking, secretion and vesicular transport, V: Defense mechanisms, W: Extracellular structures, X: Mobilome: prophages, transposons
