NCBI based taxonomic trees and the presence or absence of the eight B-vitamin biosynthesis pathways. The two taxonomic trees show the (A) 256 HGM genomes and (B) the 257 non-HGM genomes, along with heatmaps showing the presence (green) or absence (black) of each vitamin pathway. The taxonomic trees were produced using PhyloT: a tree generator (http://phylot.biobyte.de/index.html), and visualized through iTOL (http://itol.embl.de/) (Letunic and Bork, 2007, 2011).
