Plant-Microbe-Metal Interactions: A Biochemical and Molecular Analysis for Phytoremediation

Plants in nature face abiotic and biotic stress, attacked by phytopathogens and phyto-pests, which leads to loss in the productivity and health of the plants. Interaction among plant with rhizospheric microbes and soil metal contents involves various biochemical pathways which are exploited for phytoremediation. The plant-microbe interactions, plant-metal interaction, microbe-metal interactions and their involvement with each other, their role in phytoremediation and the molecular level at which all these activities are regulated, and how the plant immune system respond to it are of high significance. Plant immune system orchestrates interactions with beneficial microbes, pathogens, and insects, and this interaction is influenced by the presence of metals and provides a rational basis for developing sustainable strategies for phytoremediation. In this chapter all the aspect of plant-microbe-metals interactions in plants has been reviewed.
