Comparative analysis of Pariaconus Carsonella genomes. (A) Whole genome alignment of Carsonella-Pm with previously sequenced Carsonella-Pp genomes exhibits complete genome synteny. Scaled schematic of genes is shown according to the scale bar in base pairs. Ribosomal genes are shown in grey and putative pseudogenes are shown in light blue. Multi-color shaded plot above each genome indicates the average NT similarity to the other genomes (range = 50–100%) as generated by Mauve. (B) Histidine biosynthesis genes are only detected in Carsonella genomes from galling Pariaconus psyllids. Gene presence matrix for genes involved in amino acid biosynthesis pathways (red). White cells indicate the absence of a required gene, or in the case of arginine and methionine biosynthesis the absence of multiple genes, which is indicated by a number below cells. Genes present in the free-living Triozidae outgroup (B. cockerelli) are shown in grey
