Establishment and maintenance of aphid endosymbionts after horizontal transfer is dependent on host genotype.

Abstract excerpt

Animal-associated microbial communities have important effects on host phenotypes. Individuals within and among species differ in the strains and species of microbes that they harbour, but how natural selection shapes the distribution and abundance of symbionts in natural populations is not well understood. Symbionts can be beneficial in certain environments but also impose costs on their hosts. Consequently,...
