The role of root exudates and allelochemicals in the rhizosphere
Plant roots serve a multitude of functions in the plant including anchorage, provision of nutrients and water, and production of exudates with growth regulatory properties. The root–soil interface,Expand

Weed and Crop Allelopathy
Allelopathy can be defined as an important mechanism of plant interference mediated by the addition of plant-produced secondary products to the soil rhizosphere. Allelochemicals are present in allExpand

Grass roots chemistry: meta-Tyrosine, an herbicidal nonprotein amino acid
Fine fescue grasses displace neighboring plants by depositing large quantities of an aqueous phytotoxic root exudate in the soil rhizosphere. Via activity-guided fractionation, we have isolated andExpand

Mechanisms for cellular transport and release of allelochemicals from plant roots into the rhizosphere.
Allelochemicals and other metabolites released by plant roots play important roles in rhizosphere signalling, plant defence and responses to abiotic stresses. Plants use a variety of sequestrationExpand
