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.

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. Additionally, considering necessity popularizing this technique, major challenges prospects linked systems have been discussed. © 2023 Society Chemical Industry.

Soil Health to Enhance Ecological Restoration and Conservation

Journal of Sustainable Agriculture and Environment, Год журнала: 2024, Номер 3(4)

Опубликована: Окт. 1, 2024

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.

Biopriming of Cucumis sativus L. Seeds with a Consortium of Nitrofixing Cyanobacteria Treated with Static Magnetic Field

Plants, Год журнала: 2025, Номер 14(4), С. 628 - 628

Опубликована: Фев. 19, 2025

The growing demand for sustainable agriculture necessitates innovative strategies to enhance crop productivity while minimizing environmental impact. This study explores the biopriming potential of Cucumis sativus L. seeds using extracts derived from a consortium nitrofixing cyanobacteria Nostoc commune, Calothrix sp., and Aphanothece minutissima subjected static magnetic field (SMF) treatments. cyanobacterial consortia were exposed SMF at varying inductions (40-50 mT 100-200 mT), followed by extract preparation application as agents. Results demonstrated significant improvements in key seedling growth parameters, including root stem length, vigor index I, fresh biomass. treated with 40-50 showed most pronounced growth-stimulating activity, suggesting enhanced bioactive compound production under this treatment that might be related auxin biosynthesis. Biopriming maintained balanced nutritional uptake plant health, indicated stable weight dry ratios. These findings highlight SMF-enhanced agents horticultural crops. Future research should elucidate underlying modes action optimize conditions broader applications.

Introduction The strategic utilization of plant growth-promoting (PGP) rhizospheric bacteria is a sustainable approach to mitigating the negative effects anthropogenic activities and excessive nickel (Ni) accumulation in plants. Given that specific symbiotic interactions depend on direct relationship between species, bacterial strain, heavy metals (HMs), this study aimed investigate Paraburkholderia phytofirmans PsJN seed priming Ni tolerance adult Micro-Tom tomato plants ( Solanum lycopersicum L .). Methods Sterilized seeds were bioprimed with P. for 24 hours then sown into soil. Non-primed, imbibed used as control. After 10 days, seedlings transferred Hoagland nutrient solution. Chronic (10 μM Ni) acute (50 stress conditions induced by supplementing solution salt. experiment lasted approximately 75 covering complete life cycle Various physiological biochemical parameters analyzed. Results Significant differences p < 0.05) observed non-primed terms fruit yield. Bioprimed tomatoes exhibited higher resilience stress, particularly under conditions. Non-primed treated 50 showed statistically lower concentrations chlorophyll total chlorophylls compared tomatoes. Moreover, proline content was generally more stable plants, indicating reduced oxidative stress.The activity antioxidant enzymes distinct patterns nonprimed Conclusion findings suggest biopriming enhances growth stress. This technique appears mitigate Ni-induced effects, at concentrations, making it promising strategy improving performance Ni-contaminated environments. Future studies should explore underlying molecular mechanisms field applications approach.
