More Is Not Always Better: Coinfections with Defensive Symbionts Generate Highly Variable Outcomes.

Applied and environmental microbiology - 18 Feb 2020

Weldon S R, Russell J A, Oliver K M

Abstract excerpt

Animal-associated microbes are highly variable, contributing to a diverse set of symbiont-mediated phenotypes. Given that host and symbiont genotypes, and their interactions, can impact symbiont-based phenotypes across environments, there is potential for extensive variation in fitness outcomes. Pea aphids, Acyrthosiphon pisum, host a diverse assemblage of heritable facultative symbionts (HFS) with characterized...
