Drought stress severely affects the physiology and metabolism of plants. Fortunately, using plant growth-promoting bacteria can provide an environmentally friendly solution. Hence, present experiment was conducted on sorghum for drought amelioration by utilizing Bacillus sp. Pseudacidovorax intermedius bacterization to seeds under greenhouse conditions. induced withholding water after 52 days emergence (flowering stage). However, inoculation could significantly improve tolerance capacity through production different antioxidant enzymes metabolites in plants recovery The results declared that reduced membrane leakage 37% minimizing malondialdehyde (49 & 47%) hydrogen peroxide (32 36%) content. In addition protecting leakage, bacterial positively modulates namely catalase, ascorbate peroxidase, glutathione superoxide dismutase, phenol content system. Metabolomic revealed consortia up regulate carboxylic acid, organic, amino acids biomolecules expression inside inoculated study concluded is assured technology mitigating effect compounds, leaf during Further, research needs comprehend underlying molecular mechanism bacterial-induced drought-tolerant It will also create a road map develop bestselling bioinoculant climate-smart agriculture.

Abstract Background To optimize irrigation water use and productivity, understanding the interactions between plants, techniques, fertilization practices is crucial. Therefore, experiment aims to assess effectiveness of two application methods potassium humate combined with chelated zinc under partial root-zone drip techniques on maize nutrient uptake, yield, efficiency across levels. Methods Open-field experiments were carried out in summer seasons 2021 2022 alternate fixed investigate their impacts at levels applied foliar soil applications or a sole combinations maize. Results Deficit significantly increased hydrogen peroxide decreased proline, antioxidant enzymes, carbohydrate, chlorophyll (a + b), uptake both techniques. The implementation drought conditions led varying enzymes nutritional status, depending type technique. Meanwhile, results showed that diminished negative effects stress by enhancing phosphorus (53.8%), (59.2%), proline (74.4%) catalase (75%); compared control. These enhancements may contribute improving defense system plants such conditions. On other hand, same previous treatments root zone modified mechanism improved contents peroxidase, superoxide dismutase, magnesium, zinc, iron 81.3%, 82.3%, 85.1%, 56.9%, 80.2%, respectively. Conclusions Adopting 75% requirements treating 3 g l −1 1.25 kg ha technique, resulted maximum length, leaf content, efficiency.

Biological amelioration of water stress in rapeseed (Brassica napus L.) by exopolysaccharides‐producing Pseudomonas protegens ML15

Physiologia Plantarum, Год журнала: 2024, Номер 176(6)

Rapeseed (Brassica napus L.) is a globally significant oilseed crop with high economic value. However, water deficit significantly limits its growth and productivity. Exopolysaccharides (EPS)-producing bacteria offer promising strategy to counteract drought stress, leveraging their retention capabilities plant growth-promoting (PGP) properties. This study was conducted characterize the PGP traits of selected EPS-producing strains evaluate efficacy in enhancing rapeseed resilience under conditions. Among five evaluated, Pseudomonas protegens ML15 for best performance. strain demonstrated range traits, such as solubilization phosphate, potassium, zinc, alongside production ammonia, siderophores, proline. It also exhibited antioxidant activity ability form biofilms, even water-stressed Inoculation increased germination percentages seedling length. Notably, whether plants were subjected drought-induced stress or maintained normal conditions, treatment P. inoculation consistently improved length overall biomass. Under drought-stressed inoculated reduced malondialdehyde levels vegetation indices, chlorophyll, protein, proline, phenolic content. They showed enhanced enzymes, catalase peroxidase, compared uninoculated plants. These findings underscore potential like mitigate plants, providing ecological benefits that support agricultural sustainability.

Drought stress (DS) is one of the most destructive abiotic stresses that negatively affects plant growth, and yield. The intensity DS continuously increasing due rapid water sources, less rainfall, an increase in global warming. world’s population at alarming rate which needs a substantial crop production to meet food needs. Therefore, this context, we must have scenarios climate change stresses. Globally, different measures are used mitigate adverse impacts DS, recently biochar (BC) has emerged as excellent soil amendment toxic effects improve production. application maintains membrane integrity, relations, nutrient homeostasis, photosynthetic performance, hormonal balance osmolytes accumulation, gene expression thereby improving performance under DS. Moreover, BC also improves organic matter, holding capacity, structure stability, activity beneficial microbes can In present review mechanisms through mitigates on plants discussed.

The increasing level of cadmium (Cd) contamination in soil due to the actions humans is a significant problem. This problem not only harms natural environment, but it also causes major harm human health via food chain. use chelating agent useful strategy improve heavy metal. research aimed mitigate Cd stress by application organic acids i.e., malic (MA) and tartaric acid (TA). We evaluated physiological biochemical features, growth traits Spinacia oleracea L. under stress. Soil was treated with 100 µM Cd, as well two dosages foliar sprays (100 150 µM) MA TA were applied. results this study revealed that exogenously applied significantly reduced root shoot length fresh dry weight, leaf number, area, photosynthetic pigments, gas exchange parameters, plant analysis development (SPAD), increase antioxidants S. oleracea. Malic 150µM) both at 2 may lower concentrations while enhancing nutrient uptake accumulation plants exposed environment. Tartaric overcome toxicity caused oleracea. When these chelates used they have effect on all morphological, parameters. These finding demonstrates MA, when together, ability reduce Cd-induced phytotoxicity reducing
