Crops aimed at feeding an exponentially growing population are often exposed to a variety of harsh environmental factors. Although plants have evolved ways adjusting their metabolism and some also been engineered tolerate stressful environments, there is still shortage food supply. An alternative approach explore the possibility using rhizosphere microorganisms in mitigation abiotic stress hopefully improve production. Several studies shown that rhizobacteria mycorrhizae organisms can help tolerance by enhancing plant growth; stimulating production phytohormones, siderophores, solubilizing phosphates; lowering ethylene levels; upregulating expression dehydration response antioxidant genes. This article shows secretion secondary metabolites as additional mechanism employed against stress. The understanding these mechanisms will efficacy plant-growth-promoting microorganisms.

Mechanisms and Strategies of Plant Microbiome Interactions to Mitigate Abiotic Stresses

Agronomy, Journal Year: 2022, Volume and Issue: 12(9), P. 2069 - 2069

Published: Aug. 30, 2022

Abiotic stresses are the most significant factors reducing agricultural productivity. Plants face extreme environmental conditions that may affect their biological mechanisms, thereby influencing growth and development. Microorganisms possess substantial metabolites aid in helping plants mitigate abiotic stresses. Plants’ interaction with microbes constitutes a diversified ecosystem, as sometimes both partners share mutualistic relationship. Endophytes, plant-growth-promoting rhizobacteria (PGPRs), arbuscular mycorrhizal fungi (AMFs) examples of microorganisms play an essential role alleviating and, hence, improving plant growth. The plant–microbe leads to modulation complex mechanisms cellular system. Moreover, residing microbial flora also inhibits phytopathogens, therefore, it becomes part plants’ innate defense Keeping view growing concerns, is important identify microbiome transportation nutrients maintain sustainable production. Furthermore, enabling recruit beneficial species how deal potential pathogens. Therefore, this review aims summarize impacts various stressors on productivity mitigating negative effects literature shows microbes, including PGPRs, AMFs, endophytes, adopt for ameliorating It has been observed biochar either individually or combination, can maintaining under stress conditions. Although conventional inoculation mitigates enhances productivity, advancement genetic engineering would help transfer specific genes from mitigation.
