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. Furthermore, argue coating can facilitate transgenerational associations microbes, refine plant microbiomes, maintain legacies microflora. review article aims improve biopriming approach potent valuable tool achieving agriculture successful restoration.

Abiotic stress is one of the major constraints which restrain plant growth and productivity by disrupting physiological processes stifling defense mechanisms. Hence, present work aimed to evaluate sustainability bio-priming salt tolerant endophytes for improving tolerance. Paecilomyces lilacinus KUCC-244 Trichoderma hamatum Th-16 were obtained cultured on PDA medium containing different concentrations NaCl.

Biopriming of Maize Seeds with a Novel Bacterial Strain SH-6 to Enhance Drought Tolerance in South Korea

Plants, Journal Year: 2022, Volume and Issue: 11(13), P. 1674 - 1674

Published: June 24, 2022

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.

Seed biopriming as a promising approach for stress tolerance and enhancement of crop productivity: a review

Journal of the Science of Food and Agriculture, Journal Year: 2023, Volume and Issue: 104(3), P. 1244 - 1257

Published: Oct. 12, 2023

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. This review aims critically analyze recent studies based biopriming-mediated mitigation alteration physiological, processes plants.

ABSTRACT Ecological restoration has gained increased attention to combat the global biodiversity and habitat loss driven by human activities climate change. To address these impacts, efforts apply interventions aimed at recovering native ecosystems on degraded lands. However, they tend centre vegetation‐based interventions, with limited aboveground belowground linkages. Soil health, including its physicochemical, biological functional attributes, is fundamental ecosystem resilience sustainability, provision of services, well‐being. This synthesis explores how a deeper understanding soil‐vegetation interactions can support conservation efforts. We discuss be applied from early later stages restoration, future directions novel approaches that target processes promote soil health successful plant community establishment. propose integrating practices explicitly consider linkages among vegetation, properties biota lead more effective outcomes establishment resilient, self‐sustaining ecosystems.
