The specific relationship between a legume and its mutualistic Rhizobium strain probably depends on specific recognition between chemical signals and signal receptors of the Rhizobium strain and legume species.

What is the relationship between legume and rhizobium?

  • Due to the significance of legumes as key food crops, the rhizobia-legume symbiosis is a frequently studied example of mutualism.
  • By way of organic acids, plants give the bacteroids carbon and energy in exchange for reduced nitrogen.
  • Rhizobia, a type of nitrogen-fixing soil bacterium, and legumes are able to coexist together.
  • As a result of this symbiosis, nodules develop on the plant roots, where bacteria may transform air nitrogen into plant-useable ammonia.
  • Rhizobial bacteria from the soil infect plant roots and proliferate within root nodules where they fix atmospheric N2 for plant nourishment in return for carbohydrates.
  • Rhizobial bacteria and legumes have developed a mutualistic relationship known as rhizobial mutualism.
