Phenotypic and genomic signatures of interspecies cooperation and conflict in naturally-occurring isolates of a model plant symbiont

Given the need to predict the outcomes of (co)evolution in host-associated microbiomes, whether microbial and host fitnesses tend to trade off, generating conflict, remains a pressing question. Examining the relationships between host and microbe fitness proxies at both the phenotypic and genomic levels can illuminate the mechanisms underlying interspecies cooperation and conflict. We examined naturally-occurring genetic variation in 191 …
