From: Massive horizontal gene transfer, strictly vertical inheritance and ancient duplications differentially shape the evolution of Bacillus cereus enterotoxin operons hbl, cytK and nhe

MLSA-based species relationship within B. cereus sensu lato. a: The phylogenetic tree (Maximum Likelihood Method) was calculated using the concatenated sequence of seven housekeeping genes from 142 B. cereus sensu lato strains. Arrow: Suspected first appearance of cytK-2. Empty arrows: Suspected origin of nhe a operons. b: Visualization of the sequence homology derived from a multiple sequence alignment calculated with RDP3. Color ranges (identity score: ≤ 1, 1 = identical in all sequences) from identical (white) to highly dissimilar (black)
