Heatmap of selected COG categories from different endosymbionts. Endosymbionts are sorted by genome size from the smallest (Tremblaya princeps PCVAL) to the biggest (Serratia symbiotica Cc). For each genome, the numbers of hits in each COG category are shown. P-endosymbionts living with another co-P-endosymbiont are displayed in green. Evansia muelleri Xc1, which has no co-P-endosymbiont, is displayed in blue. Serratia symbiotica Cc is an example of a coprimary symbiont of large genome. COG descriptions are showed in the bottom.
