P. vortex classification based on phylogenetic analysis and function COG clustering. (A) Phylogenetic tree based on 16 S rRNA. The abbreviated genera P - Paenibacillus, B - Bacillus, G - Geobacillus, M - Myxococcus, S - Sorangium. Bootstrap values are shown next to the branches. (B) COG profile analysis of 25 bacterial species using Pearson correlation matrix. Abundance profile vector of 4,873 COGs was calculated for 25 different bacterial species representing various taxons. The computed Pearson correlation matrix was ordered using the dendrogram clustering algorithm to identify clusters and was color-coded from dark blue representing very low correlation to dark red representing very high correlation. The Geobacillus sp. Y412MC10 is clustered with Paenibacillus species (upper left red square) and not with the rest of the Geobacillus species. Additionally, Paenibacillus larvae is not part of the Paenibacillus cluster.
