Abstract:Relatives are expected to cooperate more and compete less. In symbiotic partnerships, hosts may benefit from interacting with highly-related symbionts because there is less conflict. This has been difficult to test empirically. We used the arbuscular mycorrhizal symbiosis to study the effects of fungal relatedness on host and fungal benefits, creating fungal networks varying in relatedness (self vs. non-self) between two host plants, in both soil and in-vitro systems. To determine how fungal relatedness affect… Show more
