—B-vitamin biosynthetic metabolic capabilities of obligate symbiotic consortia of different aphid species. Diagram summarizing the metabolic capabilities of the fixed endosymbiotic consortia of co-obligate symbiotic systems of Lachninae aphids. For comparison, a collapsed representation of Aphididae Buchnera-only systems is used as an outgroup. The names of genes coding for enzymes involved in the biosynthetic pathway are used as column names. Each row’s boxes represent the genes coded by a symbiont’s genome. At the right of each row, the genus for the corresponding symbiont. Abbreviations for the aphids harboring the symbionts is shown at the left of each group rows and goes as follows. Aph=Aphididae; Ctuj=C. tujafilina; Cstr=C. strobi; Cced=C. cedri; Tsal=T. salignus. On the bottom, lines underlining the genes involved in the pathway leading to the compound specified by the name underneath the line.
