The biotic and abiotic stresses are major constraints for crop yield, food quality and global food security. A number of parameters such as physiological, biochemical, molecular of plants are affected under stress condition. Since the use of inorganic fertilizers and pesticides in agriculture practices cause degradation of soil fertility and environmental pollutions. Hence it is necessary to develop safer and sustainable means for agriculture production. The application of plant growth promoting microbes (PGPM) and mycorrhizal fungi enhance plant growth, under such conditions. It offers an economically fascinating and ecologically sound ways for protecting plants against stress condition. PGPM may promote plant growth by regulating plant hormones, improve nutrition acquisition, siderophore production and enhance the antioxidant system. While acquired systemic resistance (ASR) and induced systemic resistance (ISR) effectively deal with biotic stress. Arbuscular mycorrhiza (AM) enhance the supply of nutrients and water during stress condition and increase tolerance to stress. This plant-microbe interaction is vital for sustainable agriculture and industrial purpose, because it depends on biological processes and replaces conventional agriculture practices. Therefore, microbes may play a key role as an ecological engineer to solve environmental stress problems. So, it is a feasible and potential technology in future to feed global population at available resources with reduced impact on environmental quality. In this review, we have attempted to explore about abiotic and biotic stress tolerant beneficial microorganisms and their modes of action to enhance the sustainable agricultural production.

植物与微生物的相互作用是否赋予植物抗逆性?

生物和非生物胁迫是作物产量,食品质量和全球粮食安全的主要制约因素。植物的生理,生化,分子等许多参数在胁迫条件下都会受到影响。由于在农业实践中使用无机肥料和农药会导致土壤肥力下降和环境污染。因此,有必要发展更安全,可持续的农业生产手段。在这种条件下,促进植物生长的微生物(PGPM)和菌根真菌的应用可以促进植物的生长。它提供了一种经济上引人入胜且生态上合理的方法来保护植物免受胁迫。PGPM可以通过调节植物激素,改善营养获取,铁载体生产和增强抗氧化系统来促进植物生长。获得性全身抗性(ASR)和诱导性全身抗性(ISR)有效地应对了生物胁迫。丛枝菌根(AM)可以在压力条件下增加养分和水分的供应,并增加对压力的耐受性。这种植物与微生物的相互作用对于可持续农业和工业目的至关重要,因为它依赖于生物过程并取代了常规的农业实践。因此,微生物可以作为生态工程师来解决环境压力问题。因此,将来以可行的资源来养活全球人口是一种可行且潜在的技术,而对环境质量的影响将减少。在这篇评论中,
