what if u were a luguminous plant describe your symbiotic relationships with examples
Answers
Answer:
Legumes form a unique symbiotic relationship with bacteria known as rhizobia, which they allow to infect their roots. This leads to root nodule formation where bacteria are accommodated to convert nitrogen from the air into ammonia that the plant can use for growth
Explanation:
Legumes form a unique symbiotic relationship with bacteria known as rhizobia, which they allow to infect their roots. This leads to root nodule formation where bacteria are accommodated to convert nitrogen from the air into ammonia that the plant can use for growth. This symbiotic nitrogen fixation allows legumes to thrive in habitats with limited nitrogen availability.
Researchers from Denmark and Germany have now found that an intact nitrogen-fixing symbiosis in Lotus japonicus is needed for the establishment of taxonomically diverse and distinctive bacterial communities. Integrating these highly specific binary interactions into an ecological community context is critical for understanding the evolution of symbiosis and efficient use of rhizobia inoculum in agricultural systems.
Legumes are known as pioneer plants colonising marginal soils, and as enhancers of the nutritional status in cultivated soils. This beneficial activity has been explained by their capacity to engage in symbiotic relationship with nitrogen-fixing rhizobia. The beneficial effect of this symbiosis is not limited to legume hosts, but extends to subsequent or concurrent plantings with non-legumes as exemplified by ancient agricultural practices with legume cropping sequences or intercropping systems. This symbiosis likely involves a beneficial activity of legumes on the nutritional status of the soil as well as the soil biome. However, the mechanisms underpinning these symbiotic interactions in a community context and their impact on the complex microbial assemblages associated with roots remain largely unknown.
