| mutualism effectiveness and vertical transmission of symbiotic fungal endophytes in response to host genetic background. | certain species of the pooideae subfamily develop stress tolerance and herbivory resistance through symbiosis with vertically transmitted, asexual fungi. this symbiosis is specific, and genetic factors modulate the compatibility between partners. although gene flow is clearly a fitness trait in allogamous grasses, because it injects hybrid vigor and raw material for evolution, it could reduce compatibility and thus mutualism effectiveness. to explore the importance of host genetic background in ... | 2012 | 23346228 |
