Abstract Drought, a widespread abiotic stressor, exerts profound impact on agriculture, impeding germination and plant growth, reducing crop yields. In the present investigation, osmotolerant rhizobacteria Bacillus casamancensis strain MKS‐6 sp. MRD‐17 were assessed for their effects molecular processes involved in mustard under osmotic stress conditions. Enhancement was evidenced by improved percentages, plumule radicle lengths, seedling vigor upon rhizobacterial inoculation no Under stress, stimulated production of gibberellins reserve hydrolytic enzymes (lipases, isocitrate lyase, malate synthase), bolstering germination. Furthermore, these influenced hormones such as abscisic acid (ABA), well signalling pathways, thereby promoting stress. Reduced proline glycine betaine accumulation, down‐regulation transcription factors BjDREB1_2 BjDREB2 (linked to ABA‐independent signalling) rhizobacteria‐inoculated seedlings indicated that bacterial treatment mitigated water deficit during germination, independently pathways. Hence, advantageous attributes exhibited strains can be effectively harnessed alleviate drought‐induced crops, potentially through development targeted bio‐formulations.

Seed quality as a proxy of climate-ready orphan legumes: the need for a multidisciplinary and multi-actor vision

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Опубликована: Авг. 1, 2024

In developing countries, orphan legumes stand at the forefront in struggle against climate change. Their high nutrient value is crucial malnutrition and chronic diseases prevention. However, as ‘orphan’ definition suggests, their seed systems are still underestimated production scanty. Seed priming an effective, sustainable strategy to boost quality for which up-to-date guidelines required guarantee reliable reproducible results. How far we along this path? What do expect from priming? This brings other relevant questions. socio-economic relevance of Mediterranean Basin? potentiate a broader cultivation specific regions? The case study BENEFIT-Med (Boosting technologies towards resilient farming systems) project, developed by multidisciplinary research networks, envisions roadmap producing new knowledge innovative improve productivity through priming, with long-term objective promoting sustainability food security for/in climate-sensitive regions. review highlights existing drawbacks that must be overcome before could reach state ‘climate-ready crops’. Only integration biology, technology agronomy, barrier between bench local agricultural fields may overcome, generating high-impact technical innovations legumes. We intend provide powerful message encourage future line United Nations Agenda 2030 Sustainable Development.

This research study investigated the production and properties of zinc oxide (ZnO) nanoparticles derived from corn husks their priming effects on wheat plant proliferation antioxidant mechanisms compared to nutri-priming technique under regular irrigation drought-stressed conditions. Transmission scanning electron microscopy (TEM SEM), energy-dispersive X-ray spectroscopy (EDAX), diffraction confirmed nanoparticles’ hexagonal morphology typical dimensions 51 nm. The size stability these were assessed through distribution zeta potential analysis, indicating reasonable stability. Fourier-transform infrared (FTIR) detected newly formed functional groups. emphasized role reactive oxygen species (ROS) phenolic compounds in responses nanoparticle treatment, particularly detoxifying harmful radicals. also examined activity enzymes, including peroxidase (POX), catalase (CAT), glutathione reductase (GR), alleviating stress caused by oxidation while subjected various treatments, micronutrient seed with DR GREEN fertilizer. Some biochemical compounds, such as total phenolics (TPCs), flavonoids (TFCs), hydrolysable sugars, estimated well show effect different treatments plants. findings suggested that ZnO can enhance enzyme certain conditions posing phytotoxic risks, underscoring complexity plant–nanoparticle interactions for improving crop resilience targeted applications.

Progress of in situ conservation and use of crop wild relatives for food security in a changing climate: a case of the underutilised Vigna Savi

Frontiers in Sustainability, Год журнала: 2025, Номер 6

Crop wild relatives (CWRs) - plant taxa genetically closely related to domesticated plants are considered an alternative pathway solving global food insecurity in a changing climate. However, their potential contribution is undermined by fundamental knowledge gaps diversity, distributions, taxonomic affiliations, conservation strategies, and valuable traits. To address these gaps, we reviewed the literature on progress made between 2000 2021 support of situ use CWRs under climate five thematic areas focusing genus Vigna : (1) species distribution, status, gene pools, importance genus; (2) CWR- conservation-protected area debate; (3) cultivation domestication CWR populations; (4) adaptive response drought stress; (5) Striga stress. We report that 104 subgenera, Ceratotropis , Haydonia Lasiosporon Plectotropis distributed mostly Africa Asia. Nine while six threatened. pools remain poorly understood. Many provide various ecosystem services for human environmental health. Attention increasing towards CWRs, within outside protected areas, complemented ex approaches. Several exhibit good agronomic traits neo-domestication. have demonstrated tolerance stress race-specific resistance. conclude if effectively conserved used, can contribute sustainable climate-resilient systems, either as edible plants, new neo-domestication or novel sources genetic material pre-breeding programmes improve resilience, quantity quality domesticates This study could stimulate further research policy change effective security

Priming agents combat copper stress in wheat (Triticum aestivum L.) under hydroponic conditions: Insights in impacts on morpho–physio–biochemical traits and health risk assessment

Ecotoxicology and Environmental Safety, Год журнала: 2025, Номер 291, С. 117899 - 117899

Опубликована: Фев. 1, 2025

In recent years, the use of priming agents, such as silicon, melatonin, salicylic acid, glycine betaine, and ascorbic acid has gained significant attention for their role in mitigating abiotic stresses across various plant species. While previous research been conducted on individual impact metal stress resistance among crop species, combined effects context heavy stressed conditions remain underexplored. Wheat (Triticum aestivum L.) seedlings was grown under toxic concentration copper (Cu) i.e., 100 µM which were applied with hydroponic 21 days. The outcomes indicated that Cu nutrient solution notably reduced growth biomass, photosynthetic pigments, gas exchange attributes. However, also induced oxidative plants by increasing malondialdehyde (MDA), hydrogen peroxide (H2O2) increased compounds enzymatic non-enzymatic antioxidants, health risk index (HRI) gene expression sugar content. Furthermore, a increase proline metabolism, AsA-GSH cycle, pigmentation cellular components observed. Although, application different showed characteristics, compounds, decreased HRI. addition, agents enhanced fractionation metabolism cycle T. seedlings. These results open new insights sustainable agriculture practices hold immense promise addressing pressing challenges contamination agricultural soils.

The utilization of nanotechnology in agriculture has demonstrated significant potential, particularly enhancing crop resilience to environmental stress. This study investigated the effect silver nanoparticles (AgNPs) seed treatment on soybean performance under drought conditions. used a factorial CRD with four replicates. experimental factors included treatments (control, AgNP priming, and coating) stress levels represented by field water capacity (FWC) 80%, 60%, 40%. results that AgNPs significantly increased plant growth coatings based height but did not increase all yield variables. FWC 40-60% showed severe moderate effects soybean, which decreased leaf number green index. In conclusion, had limited production could be potential approach enhance tolerance.
