How plants obtain nitrogen by supplying iron to symbiotic bacteria
Leguminous plants have a mechanism (rhizobial symbiosis) to efficiently acquire nitrogen, which is an essential macronutrient for growth, through the nitrogen-fixing bacteria rhizobia. Root nodules are organs on plant roots that facilitate the symbiotic relationship. Rhizobia coloniza these nodules and fix nitrogen by converting nitrogen from air into ammonia. Iron is needed for the enzymes … Read more
