Abstract excerpt
Mutations in maternally transmitted symbionts can affect host fitness. In this study we investigate a mutation in an obligate bacterial symbiont (Buchnera), which has dramatic effects on the heat tolerance of pea aphid hosts (Acyrthosiphon pisum). The heat-sensitive allele arises through a single base deletion in a homopolymer within the promoter of ibpA, which encodes a universal small heat-shock protein. In...
