unusual facts about actinorhizal plant



Elaeagnus multiflora

As with other species in the genus Elaeagnus, E. multiflora plants are actinorhizal, growing in symbiosis with the actinobacterium Frankia in the soil.

Frankia

Frankia is a genus of nitrogen fixing, filamentous bacteria that live in symbiosis with actinorhizal plants, similar to the Rhizobia bacteria that are found in the root nodules of legumes in the Fabaceae family.

Rhizobia

Bacteria that do associate with plants include the actinobacteria Frankia, which form symbiotic root nodules in actinorhizal plants, and several cyanobacteria (Nostoc) associated with aquatic ferns, Cycas and Gunneras.
