Flavonoids and Nod Factors: Importance in Legume-Microbe Interactions and Legume Improvement

The document from 2017 discusses the critical roles of flavonoids and Nod factors in the symbiotic relationship between legume plants and nitrogen-fixing rhizobia. Flavonoids are secondary plant metabolites that initiate this interaction by inducing rhizobial nodulation genes, which in turn produce Nod factors. These factors are essential for the formation of root nodules where nitrogen fixation occurs. The document emphasizes the potential of flavonoids and Nod factors to enhance legume growth and yield, which is beneficial for sustainable agriculture. It also explores the molecular mechanisms of these signaling factors, their role in plant defense responses, and the possibility of using biofertilizers containing Nod factors to improve legume production. Additionally, the document mentions the broader application potential of Nod factors in non-legume plants and the development of new biofertilizers that could improve the productivity of legume symbioses.
