Importance of Legumes

Legumes play a dual role as a food source and a contributor to crop rotation. Within the root nodules of legumes, nitrogen-fixing endosymbionts convert atmospheric nitrogen into various nitrogen-containing compounds that the plants can readily utilize. While many organisms cannot directly access atmospheric nitrogen, they obtain the nitrogen they need from nitrogenous compounds in the environment.

In contrast, specific bacteria and archaea can directly utilize atmospheric nitrogen. One example is Rhizobium, which converts atmospheric nitrogen into usable nitrogen-containing compounds and supplies them directly to the roots of legumes. As a result, incorporating legumes into crop rotations has become a common agricultural practice to enrich the soil with various nutrients, including nitrogenous compounds.

Certain legumes hold significance in various industries. For instance, the Acacia tree is valued for its gums, which find applications in different industrial sectors. Additionally, the Phaseolus plant produces phytohaemagglutinin (lectins) extracted for their agglutination effects on erythrocytes and leukocytes and their mitogenic properties.
