Abstract Moringa oleifera Lam . is a common edible plant, famous for several nutritional and therapeutic benefits. This study investigates the salt -induced modulations in plant growth, physio-biochemical responses, antioxidant performance of M. grown under 0, 50, 100 mM NaCl concentrations. Results showed that effectively managed moderate salinity (50 NaCl) by maintaining succulence, weight ratios, biomass allocation patterns both shoot root with minimal reduction dry biomass. However, high (100 remarkably declined all growth parameters. The accumulated more Na + Cl − , while less K as compared to control. Consequently, osmotic potentials leaf decreased salinity, which was corroborated amount proline soluble sugars. Increased level H 2 O significantly unchanged membrane fluidity indicating its role perceiving managing stress at salinity. In addition, increased activities superoxide dismutase, catalase, glutathione flavonoid contents suggest an integrated participation enzymatic non-enzymatic components regulating ROS. On other hand, caused outburst ROS indicated MDA, electrolyte leakage. As response, moringa drastically enzymes molecules including ascorbic acid, glutathione, total phenols, flavonoids radical scavenging reducing power capacities. considerable energy used such management resulting significant NaCl. suggests resisted modulating attributes ion toxicity oxidative stress. Salt also enhanced medicinal increasing compounds their activities. It can be on degraded/ saline lands this purposes, besides providing benefits global climate change scenario.

Abstract Globally, substantial research into endophytic microbes is being conducted to increase agricultural and environmental sustainability. Endophytic such as bacteria, actinomycetes, fungi inhabit ubiquitously within the tissues of all plant species without causing any harm or disease. Endophytes form symbiotic relationships with diverse can regulate numerous host functions, including resistance abiotic biotic stresses, growth development, stimulating immune systems. Moreover, endophytes play a dominant role in nutrient cycling, biodegradation, bioremediation, are widely used many industries. have stronger predisposition for enhancing mineral metal solubility by cells through secretion organic acids low molecular weight metal-specific ligands (such siderophores) that alter soil pH boost binding activity. Finally, synthesize various bioactive compounds high competence promising candidates new drugs, antibiotics, medicines. Bioprospecting novel secondary metabolites has given momentum sustainable agriculture combating stresses. Biotechnological interventions aid played pivotal crop improvement mitigate stress conditions like drought, salinity, xenobiotic compounds, heavy metals. Identification putative genes from conferring tolerance diseases, apart those involved accumulation degradation contaminants, could open avenues development. Furthermore, detailed biochemical understanding endophyte entry colonization strategy would better help manipulating productivity under changing climatic conditions. Therefore, present review highlights current trends based on SCOPUS database, potential biotechnological microorganisms stresses influencing productivity, future opportunities improving tolerance, their contribution remediation hazardous contaminants.

The modern agricultural system has issues with the reduction of productivity due to a wide range abiotic and biotic stresses. It is also expected that in future entire world population may rapidly increase will surely demand more food. Farmers now utilize massive quantity synthetic fertilizers pesticides for disease management food production. These badly affect environment, texture soil, plant productivity, human health. However, safety sustainability depend on an ecofriendly inexpensive biological application. In contrast fertilizers, soil inoculation plant-growth-promoting rhizobacteria (PGPR) one excellent alternative options. this regard, we focused best PGPR genera, Pseudomonas, which exists rhizosphere as well inside plant's body plays role sustainable agriculture. Many Pseudomonas spp. control pathogens play effective through direct indirect mechanisms. fix amount atmospheric nitrogen, solubilize phosphorus potassium, produce phytohormones, lytic enzymes, volatile organic compounds, antibiotics, secondary metabolites during stress conditions. compounds stimulate growth by inducing systemic resistance inhibiting pathogens. Furthermore, pseudomonads protect plants different conditions like heavy metal pollution, osmosis, temperature, oxidative stress, etc. Now, several Pseudomonas-based commercial products have been promoted marketed, but there are few limitations hinder development technology extensive usage systems. variability among members draws attention huge research interest genus. There need explore potential native biocontrol agents use them biopesticide support

Опубликована: Март 24, 2023

Drought stress restricts the growth of okra (Abelmoschus esculentus L.) by disrupting its biochemical and physiological functions. The current study was conducted to evaluate role selenium (0, 1, 2, 3 mg Se L−1 as a foliar application) in improving tolerance drought (control (100% field capacity-FC), mild (70% FC), severe (35% FC)) imposed 30 days after sowing (DAS). (severe) markedly decreased chlorophyll (32.21%) carotenoid (39.6%) contents but increased anthocyanin (40%), proline (46.8%), peroxidase (POD 12.5%), ascorbate (APX 11.9%), catalase (CAT 14%) activities. Overall, application significantly alleviated stress-related disturbances okra. Mainly, (21%) well (15.14%), (18.16%), antioxidant activities both under control conditions. Selenium played beneficial reducing damage caused oxidative stress, enhancing antioxidants contents, improved plant stress. Therefore, crops including especially, must be supplemented with for obtaining optimum yield arid semiarid drought-affected areas.

Опубликована: Май 26, 2023

Sustainable agriculture is threatened by salinity stress because of the low yield quality and crop production. Rhizobacteria that promote plant growth modify physiological molecular pathways to support development reduce abiotic stresses. The recent study aimed assess tolerance capacity impacts Bacillus sp. PM31 on growth, physiological, responses maize stress. In comparison uninoculated plants, inoculation improved agro-morphological traits [shoot length (6%), root (22%), height (16%), fresh weight (39%), dry (29%), leaf area (11%)], chlorophyll [Chl a (17%), Chl b (37%), total chl (22%)], carotenoids (15%), proteins (40%), sugars (43%), relative water (11%), flavonoids phenols (23%), radical scavenging (13%), antioxidants. PM31-inoculated plants showed reduction in oxidative indicators [electrolyte leakage (12%), H2O2 (9%), MDA (32%)] as compared under increased level osmolytes [free amino acids (36%), glycine betaine proline (11%)]. enhancement was further validated profiling PM31. Moreover, these mechanisms were accompanied upregulation stress-related genes (APX SOD). Our found has crucial substantial role reducing through processes, which may be used an alternative approach boost production yield.
