This study shows that drought stress drives rapid evolution in Rhizobium bacteria, enhancing their benefits to legume hosts under drought conditions.

This study shows negative frequency-dependent selection maintains genetic variation in legume-rhizobium mutualisms by favoring high-quality strains when rare.

The paper examines how ecological and evolutionary processes interact to cause mutualism breakdown between legumes and rhizobia over 33 years of nitrogen fertilization.

The paper examines how elevated CO2 affects fungal and bacterial communities in soybean phyllosphere, finding shifts in fungal composition and network structure.

The paper analyzes plasmid transmission dynamics in Rhizobium leguminosarum, finding variation in plasmid types and their association with partner quality decline due to nitrogen fertilization.
