Flavonoids have been recognised as one of the largest and most widespread groups of
plant secondary metabolites, with marked antioxidant properties. The general name …

Numerous reports have been published on the occurrence, isolation, and characterization of
phenolic compounds in plant‐soil systems. The low molecular weight phenolics are of great …

Plant diversity in experimental systems often enhances ecosystem productivity, but the
mechanisms causing this overyielding are only partly understood. Intercrop** faba beans …

NodD1 is a member of the NodD family of LysR-type transcriptional regulators that mediates
the expression of nodulation (nod) genes in the soil bacterium Sinorhizobium meliloti. Each …

Flavonoid compounds distribute widely in vascular plants and Bryophytes, and ca. 5,000
kinds have been reported as naturally occurring substances. Many biological activities of the …

In the formation of legume-rhizobia symbioses flavonoids released from roots and seeds are
best known as inducers of the bacterial nodulation genes that control the synthesis of …

Legumes are a highly important source of food, feed, and biofuel crops. With a few
exceptions, these plants can enter into a complex symbiotic relationship with specific soil …

Flavonoid signals from alfalfa (Medicago sativa L.) seed and root exudates induce
transcription of nodulation (nod) genes in Rhizobium meliloti. The flavone luteolin previously …

Rhizosphere, the interface between soil and plant roots, is a chemically complex
environment which supports the development and growth of diverse microbial communities …

Rhizobia have the ability to infect and establish a N2-fixing symbiosis with many leguminous
and a few nonleguminous plants. The result of this interaction is the formation of a novel …
