Plant Microbe Interactions

Plant roots communicate with microbes during a classy manner through chemical communication within the rhizosphere, thereby leading to biofilm formation of beneficial microbes and, within the case of plant growth-promoting rhizomicrobes/-bacteria, leading to priming of defense, or induced resistance within the plant host. The knowledge of plant–plant and plant–microbe interactions are greatly extended over recent years; however, the chemical communication leading to priming is much from being well understood. Furthermore, linkage between below- and above-ground plant physiological processes adds to the complexity. Plant—microbe encounters can be friendly or hostile. Densely colonized soil contains beneficial mycorrhizal fungi and rhizobia, which accompany roots and supply plants with mineral nutrients and glued nitrogen, respectively, in exchange for carbon. By contrast, plants are constantly exposed to a selection of fungal, bacterial and viral pathogens, and have evolved unique defense mechanisms to fight these infections. Plant community dynamics are driven by the microbial mediation of soil resource partitioning and sharing by the inhibition of other host symbionts or sharing the broadly specific symbiotic fungi. The plant phenotype and ecology are often suffering from the impact of the symbiotic microbes on the environment and competition for soil resources. Plants have recently been recognized as a met organism that possesses a definite micro biome and shut symbiotic relationships with associated microorganisms. Plant ecology is suffering from complex interactions with plant-associated microbes. The roles of both plant-associated microbes and therefore the host in ecosystem function are recognized, but the detailed mechanisms are unclear. Since plants are immobile, they need coevolved with microbes and purchased variety of mechanisms that modulate the result of their interactions.
