Brief historical review

Our research group has been studying microorganism-plant interactions for several years, focusing mainly on the phylum Actinobacteria and their relationship with leguminous plants. The collection currently has more than 1300 bacterial isolates from rhizosphere and plant tissues (nodules, roots, leaves...) and about 700 isolates from other environments (compost, Atacama Desert, etc.). We are currently focused on the microbiome of different legume species.
