One such novel idea is that of inserting into the chromosomes of plants discrete genes that are not a part of the plants’ natural constitution：specifically，the idea of inserting into nonleguminous plants the genes，if they can be identified and isolated，that fit the leguminous plants to be hosts for nitrogen-fixing bacteria. Hence，the intensified research on legumes.
