Figure 1. Pan-genome of Serratia spp.
Euler diagram displaying the number of clusters found on each subspace of the pan-genome. The pan-genome defined here as the total collection of CDS clusters found in S. symbiotica SCc, S. symbiotica SAp, S. proteamaculans 568, S. odorifera 4R×13 and S. marcescens Db11 (first two obligate and facultative endosymbiont respectively and the rest free-living).
