Genome sequencing and assembly of Vavilovia formosa symbionts

The evolution research of rhizobium-legume symbiosis on the example of isolates from the relict legume Vavilovia formosa. Some of these isolates are similar to the evolutionary early symbionts (Rhodopseudomonas, Bradyrhizobium) other to evolutionary advanced forms like Rhizobium leguminosarum. Isolated strains may represent “living evidence” of evolutionary pathway of the rhizobium-legume symbiosis. These include both the transition from free-living bacteria to plant symbionts and the fine-tuning of host specificity.
