Evolution of specialization in a plant-microbial mutualism is explained by the oscillation theory of speciation

This is a compilation of the different sets of data that were gathered and analyzed to understand the evolution of plant-microbial mutualisms in a genus of native legumes in California (Acmispon) described in the paper: \"Torres-Martínez L, Porter SS, Wendlandt CE, Purcell J, Ortiz-Barbosa GS, Rothschild J, Lampe M, Warisha F, Le T, Weisberg AJ, Chang JH, Sachs JL. Evolution of specialization in a plant-microbial mutualism is explained by the oscillation theory of speciation. Evolution. 2021 Mar 30. doi: 10.1111/evo.14222\". Here we use a multidisciplinary approach were niche modeling, phylogenetic approaches and a manipulative green house experiment were implemented to test two specific hypothesis on the evolution of specialization: whether generalist interactions evolve to become more specialized or if partner switches evolve without any change in niche breadth.

First, we assesed the rhizobia taxa that associate with Acmispon spp in nature by performing field collections of root nodu...
