Symbiotic Strategies for Plant Stress Tolerance: The Role of Beneficial Microbes and Omics in Sustainable Agriculture
摘要
Abiotic and biotic stresses pose significant challenges to agricultural productivity, often resulting in substantial yield losses. Reliance on chemical pesticides has not satisfactorily mitigated these challenges. Hence, there is a need to explore more sustainable management measure that leverages the beneficial microbe-plant symbiotic relationship, an association that is fundamental to achieving crop resilience, nutrient acquisition, and plant tolerance to stress and diseases. The beneficial microbes consisting of the plant growth-promoting rhizobacteria (PGPR), nitrogen-fixing bacteria, and mycorrhizal fungi enhance plant productivity and health through their modulation of phytohormone levels, nutrient solubilization, production of bioactive compounds, and ability to induce systemic resistance mechanism against pathogens, drought, or saline conditions. Hence, this review explores the functional roles of microbe-plant interaction that confers induced tolerance to plants. The current advances in biotechnology offer new insight into engineering the microbial consortia that is tailored for specific crop and stress conditions. It further explores the new frontiers of research in the microbe-plant symbiosis, highlighting its application in sustainable agriculture and the development of climate-resilient cropping systems. Understanding and harnessing the benefits of this interaction will result in the practice of sustainable agriculture and stress management while improving climate resilience and crop productivity without dependency on chemical use.
