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.

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.

Germination and seedling development are essential stages in a plant’s life cycle, greatly influenced by temperature moisture conditions. The aim of this study was to determine maize (Zea mays L.) seeds’ germination under various abiotic stresses. Eight different levels, 5, 10, 15, 20, 25, 30, 35, 40 °C, were used.

This process is referred priming-induced or acquired response. In this review, we discuss how (i) storage retrieval from memory modulates plant physiological, cellular, processes in response stress(es), (ii) intensity, recurrence, duration priming stimuli influences outcomes response, (iii) varying responses at different developmental stages.

Abstract The utilization of microbial inoculants in the realm sustainable agricultural and ecosystem restoration has witnessed a surge recent decades. This rise is largely attributed to advancements our understanding plant–microbe interactions, urgency reduce dependence on agrochemicals growing societal demand for strategies management. However, despite rapid growth bio‐inoculants sector, certain limitations persist concerning their efficacy performance under field condition. Here, we propose that seed biopriming, an effective inoculant technique integrating both biological agents (the priming beneficial microbes seeds) physiological aspects (hydration seeds improved metabolically activity), significant potential mitigate these limitations. method increases protection against soil‐borne pathogens soil pollutants, such as salts heavy metals, while promoting germination rate uniformity, leading overall primary productivity health.

Volatile organic compounds (VOCs) produced by potential plant growth-promoting rhizobacteria (PGPR) play an important role in interactions. However, the mechanisms underlying this phenomenon are not well understood.
