Flavonoids are crucial signaling molecules in the symbiosis between legumes and their
nitrogen-fixing symbionts, the rhizobia. The primary function of flavonoids in the interaction is …

Plant developmental processes are controlled by internal signals that depend on the
adequate supply of mineral nutrients by soil to roots. Thus, the availability of nutrient …

Advances in the flavonoid field have been nothing short of spectacular over the last 20
years. While the medical field has noticed flavonoids for their potential antioxidant …

Flavonoids are a class of low molecular weight phenolic compounds that is widely
distributed in the plant kingdom. They exhibit a diverse spectrum of biological functions and …

Plants produce and release in the surrounding soil, the so-called rhizosphere, a vast variety
of secondary metabolites. Among them, flavonoids are the most studied, mainly for their role …

Rhizobium, Bradyrhizobium, and Azorhizobium species are able to elicit the formation of
unique structures, called nodules, on the roots or stems of the leguminous host. In these …

Inputs of biologically fixed nitrogen derived from the symbiotic relationship between legumes
and their root-nodule bacteria into terrestrial ecosystems amount to at least 70 million metric …

In Rhizobium leguminosarum biovar viciae, the nodABC and nodFEL operons are involved
in the production of lipo-oligosaccharide signals which mediate host specificity. The …

At least three different sets of symbiotic signals (here, they are compared to locks and keys)
are exchanged between legumes and rhizobia during nodule development. Flavonoids, the …

The view that symbiotic legumes benefit companion and subsequent plant species in
intercrop and rotation systems is well accepted. However, the major contributions made …
