Abstract
Root the ‘hidden’ part of the plant is the first organ to emerge from a seed. The main functions of this root system have traditionally been thought to be anchorage and uptake of nutrients and water. However, root also secretes an enormous range of compounds into the surrounding soil, called the root exudates Plants mediate both positive and negative interactions in the rhizosphere via root exudates, the positive interactions include symbiotic associations with beneficial microbes, such as rhizobia, mycorrhiza and plant growth promoting rhizobacteria (PGPR) and negative interactions include associations with parasitic plants, pathogenic microbes and invertebrate herbivores. The role of root exudates in mineral acquisition and metal detoxification is also well established. This article attempts to provide the overall concept of Root exudates and its impact on rhizospheric environment.
