Experimental evolution makes microbes more cooperative with their local host genotype.

TL;DR: Local and recent associations between bacterial strains and plant genotypes are due to selection for bacterial adaptation, and cooperation depends on the match between partner genotypes and increases as bacteria adapt to their local host.

Geographically structured genetic variation in the Medicago lupulina-Ensifer mutualism
TL;DR: Characterizing and comparing the population genomic structure of the legume Medicago lupulina and two rhizobial species and suggesting that there is potential for geographically structured coevolution between M. lupULina and the Ensifer genus, but not between either Ensifer species.
More partners, more ranges: generalist legumes spread more easily around the globe
TL;DR: It is found that generalist legumes occur in more introduced ranges than specialist legumes, suggesting that among mutualists, specialization hinders range expansions.

No evidence for adaptation to local rhizobial mutualists in the legume Medicago lupulina
TL;DR: Testing whether the legume Medicago lupulina is adapted to the locally abundant species of mutualistic nitrogen-fixing bacteria (“rhizobia”) demonstrates that symbiont local adaptation is weak in this mutualism despite large-scale geographic variation in the identity of the interacting species.

Combining phenotypic and genomic approaches reveals no evidence for adaptation to the local mutualist in Medicago lupulina
TL;DR: Testing whether the legume Medicago lupulina is locally adapted to two species of mutualistic nitrogen-fixing rhizobial bacteria that vary in frequency across its eastern North American range demonstrates that local adaptation has not evolved in this mutualism despite large-scale geographic variation in the identity of the interacting species.
