Climatic changes and global warming produce abiotic stressors that affect plant development productivity. Abiotic stressors, such as drought, salt, cold, heat, significantly impair agricultural crop yields. The endophyte is a type of endosymbiont, usually bacteria or fungus lives inside cells doesn't cause disease in the host plant. This review scrutinizes integral contribution endophytes to augmenting stress tolerance plants. core analysis investigates regulatory role mechanism pivotal physiological aspects plants under conditions. includes their involvement managing water uptake maintaining balance during drought salinity stress, regulating osmotic scavenging reactive oxygen species (ROS). Additionally, explores outlines diverse strategies for inoculating applying enhance Endophytes secondary active compounds defend from diseases extracellular enzymes help colonize hosts. Microbial may thrive poor soil conditions through phytohormone production hazardous chemical degradation. use many processes survive nutritional deficiency, heavy metal temperature. These findings suggest rhizobacteria cope with stress. Still, more research needed understand mechanisms side effects maximize sustainable climate-smart agriculture.

Abstract Background Spot blotch is a serious foliar disease of barley ( Hordeum vulgare L.) plants caused by Bipolaris sorokiniana, which hemibiotrophic ascomycete that has global impact on productivity. Some Trichoderma spp. promising candidate as biocontrol agent well plant growth stimulant. Also, the application nanomaterials in agriculture limits use harmful agrochemicals and helps improve yield different crops. The current study was carried out to evaluate effectiveness Trichoderma. cf . asperellum biosynthesized titanium dioxide nanoparticles (TiO 2 NPs) manage spot B. sorokiniana assess plant’s innate defense response.

Plant-growth-promoting rhizobacteria (PGPR) could potentially enhance photosynthesis and benefit plant growth by improving soil nutrient uptake affecting hormone balance. Several recent studies have unveiled a correlation between alterations in host resistance levels. Photosynthesis provides materials energy for immune defense affects defense-related signaling pathways. Photosynthetic organelles, which be strengthened PGPR inoculation, are key centers signal biosynthesis transmission. Although endophytic PGPRs metabolize photosynthates, they can increase soluble sugar levels alternate type distribution. Soluble sugars clearly support act as secondary messengers under stressed conditions. Overall, carbohydrate metabolism modifications induced may also play role resistance. We provide concise overview of current knowledge regarding PGPR-induced modulation both pathogen-infected pathogen-free highlight application cost-saving strategy amidst unpredictable pathogen pressures.

Abstract Key message Arbuscular mycorrhizal fungi generated systemic acquired resistance in cucumber to Zucchini yellow mosaic virus , indicating their prospective application the soil as a sustainable, environmentally friendly approach inhibit spread of pathogens. The wide plant pathogens affects whole world, causing several diseases and threatening national food security it disrupts quantity quality economically important crops. Recently, acceptable mitigating practices have been required for sustainable agriculture, restricting use chemical fertilizers agricultural areas. Herein, biological control (ZYMV) ( Cucumis sativus L.) plants using arbuscular (AM) was investigated. Compared plants, ZYMV-infected displayed high disease incidence (DI) severity (DS) with various symptoms, including severe mosaic, mottling green blisters leaves. However, AM fungal inoculation exhibited 50% inhibition these symptoms limited DS 26% compared non-colonized ones. detection ZYMV by Enzyme-Linked Immunosorbent Assay technique significant reduction AM-inoculated (5.23-fold) Besides, root colonization (F%) slightly reduced infection. infection decreased all growth parameters pigment fractions increased malondialdehyde (MDA) content, however, were significantly enhanced MDA content colonization. Also, protein, proline antioxidant enzymes (POX CAT) more enhancements due Remarkably, defence pathogenesis-related (PR) genes such PR-a, PR-b, PR-10 quickly expressed response treatment. Our findings demonstrated beneficial function triggering against they caused supported potential an environment-friendly method hindering pathogenic microorganisms sustainably.

This study aimed to investigate the biocontrol activity of rhizosphere isolates against late blight disease tomatoes caused by fungus Phytophthora infestans. A total 30 rhizospheric bacterial were evaluated for their antagonistic P. infestans in vitro and vivo. The results demonstrated that among tested, six (RS65, RP6, RS47, RS46, RP2, RS61) exhibited a highly significant inhibitory effect (p < 0.001) on mycelial growth vitro, with inhibition rate exceeding 67%. Among isolates, RS65 highest at 78.48%. For mechanisms, enzymatic activity, including proteolytic, lipolytic, chitinolytic as well production HCN, cellulase, pectinase. Isolate RS65, which showed rate, was further under greenhouse conditions. investigation revealed differences severity between control treatment. level 31.26%, whereas treatment achieved lowest 16.54%. Molecular identification indicated isolate (accession numbers PV208381) is Bacillus genus 99% proximity velezensis. finding suggests could provide effective protection infection tomato plants. These findings highlight potential agent integrated management blight.

Abstract Background Enhancing crops’ drought resilience is necessary to maintain productivity levels. Plants interact synergistically with microorganisms like Beauveria bassiana improve tolerance. Therefore, the current study investigates effects of biopriming B. on tolerance in Malva parviflora plants grown under regular irrigation (90% water holding capacity (WHC)), mild (60% WHC), and severe stress (30% WHC). Results The results showed that reduced growth physiological attributes M. . However, those bioprimed higher enhanced growth, physiological, biochemical parameters: enriched malondialdehyde H 2 O contents. Conversely, exposure markers significantly increased proline ascorbic acid content stress; it gibberellic ethylene. Bioprimed , conditions, improved antioxidant enzymatic activity plant’s nutritional status. Besides, ten Inter-Simple Sequence Repeat primers detected a 25% genetic variation between treatments. Genomic DNA template stability (GTS) decreased slightly was more noticeable response however, for drought-stressed plants, retained GTS. Conclusion Under ’s value. This could attenuate photosynthetic alterations, up-regulate secondary metabolites, activate system, genome integrity.
