Environmental variation impacts trait expression and selection in the legume-rhizobium symbiosis

Batstone, Rebecca T.; Peters, Madeline A. E.; Simonsen, Anna; Stinchcombe, John R.; Frederickson, Megan E.


PREMISE: The ecological outcomes of mutualism are well known to shift across abiotic or biotic environments, but few studies have addressed how different environments impact evolutionary responses, including the intensity of selection on and the expression of genetic variance in key mutualism-related traits.METHODS: We planted 30 maternal lines of the legume Medicago lupulina in four field common gardens and compared our measures of selection on and genetic variance in nodulation, a key trait...[Show more]
