Role of Bacteria in Leguminous Plants
Leguminous plants are known to have a symbiotic relationship with certain bacteria known as rhizobia. This relationship is important as it helps these plants to obtain the necessary nitrogen required for growth and development. The role of bacteria in leguminous plants can be explained as follows:
Conversion of Atmospheric Nitrogen into Soil Nitrates
The bacteria present in the root nodules of leguminous plants have the ability to convert atmospheric nitrogen gas into a form that is usable by the plant. This process is known as nitrogen fixation, and it is carried out by the enzyme nitrogenase present in the bacteria. The bacteria convert the nitrogen gas into ammonia, which is then further converted into ammonium ions. These ions are then used by the plant to synthesize amino acids and other nitrogen-containing compounds.
Importance of Nitrogen Fixation
Nitrogen fixation is an important process as it helps to increase the availability of nitrogen in the soil. Nitrogen is an essential nutrient required by plants for their growth and development. However, most plants are unable to obtain nitrogen directly from the atmosphere. They rely on soil nitrates or organic matter for their nitrogen requirements. Leguminous plants, with the help of rhizobia, are able to fix atmospheric nitrogen, which not only benefits them but also increases the nitrogen availability in the soil.
Conclusion
In conclusion, the role of bacteria in leguminous plants is crucial as they help the plant to obtain nitrogen, an essential nutrient required for growth and development. The bacteria convert atmospheric nitrogen gas into a form that is usable by the plant, thus increasing the nitrogen availability in the soil. This symbiotic relationship between the bacteria and the plant is important for the growth and development of leguminous plants.

Leguminous crops, such as peas, pulses and gram, have Rhizobium bacteria in their root nodules. ... Thus, these bacteria help in replenishing nutrients in the soil by providing nitrogen to the plants. The bacteria in turn get their food and shelter from the leguminous plants.
