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.

Globally, agriculture is under a lot of pressure due to rising population and corresponding increases in food demand. However, several variables, including improper mechanization, limited arable land, the presence biotic abiotic pressures, continually impact agricultural productivity. Drought notable destructive stress may be most serious challenge confronting sustainable agriculture, resulting significant crop output deficiency. Numerous morphological physiological changes occur plants as result drought stress. Hence, there need create mitigation techniques since these might permanently harm plant.

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.

Abstract Agriculture is undergoing a paradigm shift as it moves away from relying only on agrochemicals toward natural-based product to enhance plant growth and productivity while sustainably maintaining soil quality productivity. In this sense, microalgae bacteria offer unique potential due the growing use of novel eco-friendly products such biofertilizers, biostimulants, biopesticides. Microalgae improve crop health by fixing nitrogen, releasing trace elements, solubilizing potassium, phosphorus, producing exopolysaccharides, converting organic matter into utilizable nutrients. They also release bioactive substances including, carbohydrates, proteins, enzymes, vitamins, hormones, promote growth, control pests, mitigate stress responses. Even though has long been known that produce various signaling molecules (like phytohormones, polysaccharides, lipids, carotenoids, phycobilins, amino acids) which are effective in production, targeted applications these science still very early stages development. beneficial because they oxygen extracellular chemicals, bacteria, turn, provide with carbon dioxide, other nutrients exchange. This review discusses possible role increasing yield, protecting crops, fertility stability, points out interactions may have better enhancement production sustainable way than using either them alone.
