Whole-Genome Sequence of Serratia symbiotica Strain CWBI-2.3 ^T , a Free-Living Symbiont of the Black Bean Aphid <i>Aphis fabae</i>

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-2.3(T), 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.
