Plants are sessile organisms that face environmental threats throughout their life cycle, but increasing global warming poses an even more existential threat. Despite these unfavorable circumstances, plants try to adapt by developing a variety of strategies coordinated plant hormones, resulting in stress-specific phenotype. In this context, ethylene and jasmonates (JAs) present fascinating case synergism antagonism. Here, Ethylene Insensitive 3/Ethylene Insensitive-Like Protein1 (EIN3/EIL1) Jasmonate-Zim Domain (JAZs)-MYC2 the JAs signaling pathways, respectively, appear act as nodes connecting multiple networks regulate stress responses, including secondary metabolites. Secondary metabolites multifunctional organic compounds play crucial roles acclimation plants. exhibit high plasticity metabolism, which allows them generate near-infinite chemical diversity through structural modifications, likely have selective adaptive advantage, especially climate change challenges. contrast, domestication crop has resulted or loss phytochemicals, making significantly vulnerable stresses over time.

Drought stress affects plant growth and development through several mechanisms, including the induction of oxidative stress. To cope with drought, plants have drought tolerance mechanisms at physiological, biochemical, molecular levels. In this study, effects foliar application distilled water methyl jasmonate (MeJA) (5 50 µM) on responses Impatiens walleriana during two regimes (15 5% soil content, SWC) were investigated. The results showed that response depended concentration elicitor intensity. highest chlorophyll carotenoid contents observed SWC in pre-treated µM MeJA, while MeJA did not a significant effect a/b ratio drought-stressed plants.

Effects of Enterobacter cloacae extract, selenium nanoparticles and methyl jasmonate on shoot liquid cultures of Sarcocornia fruticosa under salinity stress

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: Jan. 11, 2025

Abstract Background The in vitro propagation of halophytes is innovative perspective for sustainable agriculture, conservation natural plants and essential raw materials industry due to increasing soil salinization decreasing freshwater availability. Sarcocornia fruticosa , a halophytic plant, may hold promise biosaline production systems achieve bioactive products. Understanding the salt tolerance mechanisms through elicitors can enhance secondary metabolites, such as phenolics flavonoids, under saline environment. This study aimed evaluate effects NaCl salinity (700 mM 1000 mM) on shoot cultures assess influence different elicitors- Enterobacter cloacae extract (BE), selenium nanoparticles (SeNPs) methyl jasmonate (MeJA) -on growth, physiological biochemical responses, isorhamnetin production. Methodology Shoot were grown controlled conditions with two concentrations NaCl, alone combination BE (0.5%), SeNPs (100 ppm), or MeJA (50 µM). Growth parameters, photosynthetic pigments, ion accumulation, osmolyte content, oxidative stress marker, enzyme activity, phenolic compound levels, analyzed determine impact elicitor treatments S. 14 days. Results Sarcorcocnia exhibited better up 700 than evidenced by higher dry weights, chlorophyll a/b ratios, enhanced antioxidant contents. Elicitation both improved growth mostly biomass, pigment contents, K + /Na reducing lipid peroxidation, however, reduced biomass mainly MDA Na accumulation. In contrast, application all stimulated compounds isorhamnetin, well contribute resistance stressful conditions. Conclusion demonstrated that PTC techniques appropriate optimize halophyte metabolite findings suggest significantly resilience stress, notable increase MEJA.

Multifunctional Role of Cytokinin in Horticultural Crops

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(3), P. 1037 - 1037

Published: Jan. 25, 2025

Cytokinins (CKs) are a class of phytohormones identified in the early 1960s and mainly responsible for stimulating cell division. Following discovery, research to help understand pluralistic roles CKs plant growth stress biology increased. With their fascinating ability, serve as an important element regulating defense–growth trade-off. Herein, we demonstrate how CK fine-tuning organogenesis different parts horticultural plants is discussed. CK’s role tailoring reproductive (flowering, sex differentiation, fruit set, attributes) has been presented. An extensive explanation CK-mediated response crops abiotic (temperature, drought, salinity) biotic stresses (fungal, bacterial, nematodes) provided. Finally, posit unexplored highlight gaps worth addressing.

Published: July 19, 2023

Exogenous application of methyl jasmonate (MeJA) improves rice drought tolerance, but its effects on yield and quality under stress during the reproductive phase remain unclear. A pot experiment was conducted to measure yield, grain quality, starch physicochemical properties three treatments: continuous flooding irrigation throughout whole growth season (CF), ten days −40 kPa at heading stage (DS), foliar spraying 100 μmol L−1 MeJA first ten-day (DM). An inbred japonica variety, Huaidao 5, experimental material, each treatment had 11 replicates for sampling. The results indicated that DS significantly reduced compared CF. With increases in superoxide dismutase (+22.2%), peroxidase activities (+10.5%), catalase (+5.0%), proline content (+5.7%), DM increased 1000-grain weight (+8.6%), filled percentage (+3.6%), (+11.1%) with DS. Regarding decreased chalkiness degree (−12.3%) protein (−3.9%) amylose (+17.2%) taste value (+7.3%) relative In addition, improved breakdown viscosity (+17.8%), gelatinization enthalpy (+17.2%), retrogradation (+28.0%), 1045/1022 cm−1 ratio (+3.0%), granule morphology conclusion, exogenous enhanced antioxidant capacity leaves, thus increase terminal stress.

Published: June 2, 2024

Salinity is a global concern and severe danger to contemporary agriculture, causing inhabitation impairing crop growth development. However, cobalt (Co), multifunctional non-essential micro-element, has an important role in improving pant development under salinity stress. In the current study, impact of Coon morphological, biochemical, nutritional, metabolic changes African marigold plants at two levels were assessed. Two concentrations Co (C1; 10mg/L C2; 20mg/L) applied as foliar application (S1; 300mM S2; 600mM) The obtained results indicated that substantially reduced plant by negatively affecting nutritional profile. Whereas C1 profoundly mitigated effects improved all studied parameters including vegetative, biochemical metabolites (amino acids, fatty organic sugars, carotenoids, flavonoids, terpenoids) reducing reactive oxygen species (ROS) methylglyoxal (MG)-induced oxidative stress, irrespective severity salinity. Interestingly, overall revealed ideal dose for stress since C2 showed some toxicity symptoms both drastically Furthermore, different scavenging pathways are discussed i.e. ROS-scavenging ascorbate-glutathione (AsA-GSH) cycle MG-detoxification glyoxalase. With limitation glutathione (GSH) pool size redox homeostasis, findings GSH played critical ROS- levels.
