Enhancing drought resistance in Dracocephalum moldavica L. through mycorrhizal fungal inoculation and melatonin foliar application

Scientific Reports, Год журнала: 2025, Номер 15(1)

This research focused on improving the drought tolerance of Dracocephalum moldavica, a plant vulnerable to water stress, by exploring combined effects melatonin spray and mycorrhizal fungus Glomus intraradices inoculation. The experiment was designed as factorial randomized study evaluate plant's morphological, physiological, phytochemical responses under different conditions (100%, 75%, 50% field capacity). findings revealed that combination inoculation significantly improved morphological traits Moldavian balm conditions. Under severe (50% capacity), chlorophyll b levels increased 26.3% 35.5%, respectively, when both treatments were applied. Stress indicators, including electrolyte leakage malondialdehyde content, substantially reduced with simultaneous application symbiosis, indicating decreased cellular damage. Moreover, treatment resulted in highest activities antioxidant enzymes catalase peroxidase, suggesting these bolster oxidative stress defense mechanisms. Additionally, alone led an increase secondary metabolites like phenolic flavonoid compounds, which further amplified treatments. also observed significant alterations essential oil composition plant. Drought α-pinene, 1,8-cineole, borneol, increases even more pronounced Conversely, geraniol geranial treatment. Overall, this demonstrates can effectively enhance moldavica its physiological characteristics biochemical composition.

The current study assessed the synergistic effects of PGPR and Si in alleviating drought stress rice. Bacteria were isolated from Phragmites australis inhabiting an urban riverbank. Among strains, Pseudomonas qingdaonensis NZ 1 showed promising results under vitro induced by PEG-6000 (-0.28 MPa). To further investigate effect silicon, a plant growth experiment was conducted comprising control (dH2O) plants treated with 1, (1 mM), 1+Si normal conditions. revealed that 1+Si-treated improved parameters, chlorophyll contents, relative water antioxidant potential, nutrient uptake Moreover, endogenous abscisic acid jasmonic levels substantially reduced, while salicylic level increased plants. expression ABA metabolic genes OsNCED3 OsCYP707A6 transcription factors OsbZIP23 OsDREB1B significantly altered. Furthermore, leaf Si, calcium, potassium, phosphorus contents drought-stressed plants, along upregulation OsLSi1. combined application offers sustainable agricultural strategy to effectively mitigate detrimental drought.

Plant Growth-Promoting Rhizobacteria Paenibacillus polymyxa HL14–3 Inoculation Enhances Drought Tolerance in Cucumber by Triggering Abscisic Acid-Mediated Stomatal Closure

Journal of Agricultural and Food Chemistry, Год журнала: 2024, Номер unknown

Опубликована: Дек. 28, 2024

Drought limits crop growth and yield. Inoculation with plant growth-promoting rhizobacteria (PGPR) emerges as a promising strategy to protect crops against drought. However, the number of drought-tolerant PGPR is limited, regulation mechanisms remain elusive. Here, we screened novel strain
