Fig. 5.

Gilliamella and Snodgrassella strains possess urea transporters and urease genes. (A) Synteny of urea transporter genes, urease genes, and flanking regions in Gilliamella. Genes are colored based on their functions. Homologous regions are shaded in gray. Homologous genes next to the urea transporters and urease genes are colored in blue shade. (B) Distribution of the urea transporter and urease genes in Snodgrassella. Strains are colored based on their populations. Crossed dots are likely pseudogenes harboring internal stop codons. As A. mellifera-derived and other Apis-derived genomes possess the same number of urea-related genes, they are collapsed into one representative genome for visualization. Near-identical genomes identified by PopCOGenT are collapsed and represented by one genome.
