Actinorhizal plant information


Actinorhizal plants are a group of angiosperms characterized by their ability to form a symbiosis with the nitrogen fixing actinomycetota Frankia. This association leads to the formation of nitrogen-fixing root nodules.

Actinorhizal plants are distributed within three clades,[1] and are characterized by nitrogen fixation.[2] They are distributed globally, and are pioneer species in nitrogen-poor environments. Their symbiotic relationships with Frankia evolved independently over time,[3] and the symbiosis occurs in the root nodule infection site.[4]
