Whole-genome sequence of Serratia symbiotica strain CWBI-2.3T, a free-living symbiont of the black bean aphid Aphis fabae

Abstract

The gammaproteobacterium Serratia symbiotica is one of the major secondary symbionts found in aphids. Here, we report the draft genome sequence of S. symbiotica strain CWBI-2.3T, previously isolated from the black bean aphid Aphis fabae. The 3.58-Mb genome sequence might provide new insights to understand the evolution of insect-microbe symbiosis.
