Isolation of rhizobia from Ontario soils that are effective at fixing nitrogen with common bean (Phaseolus vulgaris)

The paper isolates and characterizes rhizobia from Ontario soils that form symbiotic relationships with common bean, identifying diverse species and high-performing strains for potential use in inoculants.

Updated taxonomy of the family Rhizobiaceae with proposals for 10 novel genera and 35 novel combinations

This paper revisits the taxonomy of the Rhizobiaceae family, proposing 10 new genera and 35 novel combinations to resolve taxonomic inconsistencies.

Elevated rates of molecular evolution genome-wide in mutualist legumes and rhizobia

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.
