The paper shows that microbial adaptation to environmental stressors can generate benefits to plant hosts, independent of host selection.

The paper investigates how co-introduced microbes affect host colonization success and finds that non-local microbes reduce host performance.

This study examines how mutualism affects legume niches globally, finding that mutualist species occupy broader niches than non-mutualists, with effects varying by mutualism type and latitude.

This study investigates how microbial legacies and mutualists affect legume responses to drought and heat, finding that mutualists can mitigate negative impacts of drought-treated soils.

The paper shows how genotype-by-environment interactions can maintain genetic variation in mutualisms by analyzing game-theoretic models and transplant experiments.

The paper examines whether defensive ant-plant mutualisms mediated by extrafloral nectaries affect island biogeography, finding that these mutualisms do not limit colonization and may strengthen the latitudinal diversity gradient.

This study examines ant-plant mutualism strength across a latitudinal gradient in India, finding stronger mutualism at lower latitudes but increased herbivory, contradicting the Biotic Interactions Hypothesis.

This study compares molecular evolution rates between mutualistic and non-mutualistic legumes and rhizobia, finding elevated rates in mutualists but stagnant evolution in symbiosis genes.

The paper shows that host-microbiome mutualisms can arise from microbial community interactions, as synthetic communities enhance both microbial productivity and host growth more than individual strains.

The paper investigates how host genetic variation affects the assembly of leaf-associated microbiomes in Ipomoea hederacea, finding contributions from both Mendelian and quantitative genetic factors.

The paper uses RNA-Seq to identify viruses associated with variation in defensive behavior of ant-plant mutualists in the Amazon.
