Along with some related plants in the family Rhamnaceae , they nitrogen fixation fix nitrogen via root nodule s which contain Frankia bacteria. ref name clawson citation journal Appl Environ Microbiol. date 1998 September volume 64 issue 9 pages 3539 3543 pmc 106764 title Diversity of Frankia Strains in Root Nodules of Plants from the Families Elaeagnaceae and Rhamnaceae author Michael L.

Actinorhizal plants are a group of angiosperms characterized by their ability to form a symbiosis with the nitrogen fixing actinobacteria Frankia . This association leads to the formation of nitrogen fixing root nodules. Classification Actinorhizal plants are dicotyledon s distributed among four angiosperm Order biology orders Fagales , Cucurbitales , Fabales and Rosales , 8 Family biology families and 24 Genus genera Betulaceae Alder Alnus Casuarinaceae Gymnostoma , Casuarina , Allocasuarina , Ceuthostoma Coriariaceae Coriaria Datiscaceae Datisca , Elaeagnaceae Eleagnus , Hippophae , Shepherdia Myricaceae Myrica , Comptonia Rhamnaceae Colletia , Discaria , Kenthrothammus , Retanilla , Talguenea , Trevoa , Ceanothus Rosaceae Dryas plant Dryas , Purshia , Cowania plant Cowania , Cercocarpus , Chamaebatia . ref name Harvnb Wall 2000 Harvnb Wall 2000 ref Actinorhizal species are trees or shrubs, except for the genus Datisca . Many are common plants in temperate regions like alder , Myrica bayberry , Comptonia sweetfern , Dryas plant Avens , mountain misery and Coriaria . Some Elaeagnus species and Sea buckthorn s produce edible fruit. In tropical regions, Casuarina s are widely cultivated, becoming invasive species in some areas like Casuarina glauca in Florida . Distribution and ecology Actinorhizal plants are found on all continents except for Antarctica . Their ability to form nitrogen fixing nodules confers a selective advantage in poor soils. Most actinorhizal plants are therefore pioneer species that colonize young soils where available nitrogen is scarce like moraine s, volcanic flows or sand dunes. ref name Schwintzer 1990 Harvnb Schwintzer Tjepkema 1990 ref Being among the first species to colonize these disturbed environments, actinorhizal shrubs and trees play a critical role, enriching the soil and enabling the establishment of other species in an ecological succession . ref name Harvnb Wall 2000 ref name Schwintzer 1990 Actinorhizal plants like alders are ... more details
