Maize is the third most common cereal crop worldwide, after rice and wheat, plays a vital role in preventing global hunger crises. Approximately 50% of yields are reduced by drought stress. Bacteria as biostimulants for biopriming can improve yield enhance sustainable food production. Further, seed stimulates plant defense mechanisms. In this study, we isolated bacteria from rhizosphere Artemisia plants Pohang beach, Daegu, South Korea. Twenty-three isolates were screened growth promoting potential. Among them, bacterial isolate SH-6 was selected based on maximum induced tolerance to polyethylene glycol-simulated drought. showed ABA concentration = 1.06 ± 0.04 ng/mL, phosphate solubilizing index 3.7, sucrose 0.51 0.13 mg/mL.

Environmental changes are inevitable with time, but their intensification and diversification, occurring in the last several decades due to combination of both natural human-made causes, really a matter great apprehension. As consequence, plants exposed variety abiotic stressors that contribute morpho-physiological, biochemical, molecular alterations, which affects plant growth development as well quality productivity crops. Thus, novel strategies still being developed meet challenges modern world related climate ecosystem degradation. Innovative methods have recently received special attention include eco-friendly, easily available, inexpensive, and, very often, plant-based methods. However, such approaches require better cognition understanding adaptations acclimation mechanisms response adverse conditions. In this succinct review, we highlighted defense against external stimuli (mainly exposure elevated levels metal elements) can be activated through permanent microevolutionary metal-tolerant species or exogenously applied priming agents may ensure thereby stress resistance.

Chemicals are used extensively in agriculture to increase crop production meet the nutritional needs of an expanding world population. However, their injudicious application adversely affects soil's physical, chemical and biological properties, subsequently posing a substantial threat human health global food security. Beneficial microorganisms improve plant productivity with minimal impact on environment; however, efficacy greatly relies technique. Biopriming is advantageous technique that involves treatment seeds beneficial agents. It exhibits immense potential improving physiological functioning seeds, thereby playing pivotal role uniform germination vigor. Biopriming-mediated molecular metabolic reprogramming imparts stress tolerance plants, improves health, enhances productivity. Furthermore, it also associated rehabilitating degraded land, soil fertility, nutrient cycling. Although biopriming has vast applications agricultural system, its commercialization utilization by farmers still infancy.
