Agriculture has a long history of research targeted at understanding how to improve the effectiveness of root symbionts, viz., rhizobia and mycorrhiza. A promising approach has been employed to understand how natural selection regulates changes in mutualistic interactions. A descriptive knowledge of basic evolutionary processes can be employed to develop agricultural management practices that favor the most effective symbionts. Mutually beneficial interactions between plant and associated rhizospheric microorganisms are ubiquitous which is important for ecosystem functioning. Plant-mediated mineralization for nutrient acquisition in agroecosystem would reduce the potential for nutrient losses because of tight coupling between net mineralization of N and P and plant uptake in the rhizosphere. Microorganisms and their products in the rhizosphere react to the many metabolites that are released by plant roots in a variety of positive, negative, and neutral ways. Such interactions can influence plant growth and development, change nutrient dynamics, and alter plant’s susceptibility to biotic and abiotic stresses. This benefit can either persist or lost in well-fertilized agricultural soils where nutrients are readily available to plants and symbionts that reduce growth. |
