Abstract
Non-leguminous crops, e.g. wheat, maize and rice, do not form nodules and are dependant for their nutrition on fixed nitrogen from the soil, or from chemical/nitrogenous fertilizers. The present invention provides non-leguminous plants and leguminous plants, including legumes that fail to nodulate with Rhizobia, with bacteria that enable them to fix nitrogen endophytically. Therefore, the plants contain nitrogen fixing bacteria the bacteria being located intacellularly in living plant cells.
