Plants, Год журнала: 2025, Номер 14(6), С. 863 - 863

Опубликована: Март 10, 2025

A greenhouse trial was conducted in Southern Italy to examine the effects of foliar applications two substances, methyl-jasmonate (MeJA) and a zeolite, on harvest post-harvest performance hydroponically grown baby leaf genotypes (leafy chicory ‘Cicoria costa rossa’; kale ‘Cavolo nero’). MeJA is phyto-hormone primarily studied for fruit applications, while zeolite typically used pest disease biological control. (Sigma-Aldrich Merck KGaA, Darmstadt, Germany), commercial (Big-Zeo, Agricola Internazionale s.r.l., Pisa, Italy) (BigZeo) were sprayed twice at second fourth true stages (BigZeo, 5 kg ha−1; MeJA, 250 µM). Bio-physiological (yield, dry matter DM, chlorophyll CHL, weight loss WL) qualitative (nitrate, carotenoids, phenols, flavonoids, anthocyanins, antioxidant activity) traits evaluated both raw fresh-cut (7 day-cold-stored) products. Treatments did not significantly affect yield (1.0 m−2), plant responses substances concerning other genotype-dependent. enhanced greenness (CHL), texture (DM), activity (by increasing carotenoids flavonoids) chicory. In contrast, improved greenness, texture, phenols), reduced nitrate kale. (2.2 g 100 g−1 f.w., average). After 7 days storage, MeJA-treated zeolite-treated exhibited textural nutritional quality.

Jasmonate Promotes Ester Aroma Biosynthesis during Nanguo Pears Storage

Horticulturae, Год журнала: 2024, Номер 10(4), С. 329 - 329

Опубликована: Март 28, 2024

Volatile organic compounds (VOCs) have been known to confer the flavor of fruits, characterizing quality fruits. Nanguo pear (Pyrus ussuriensis Maxim.) is widely popular among consumers due its excellent ‘fruity’ aroma derived from ester substances. Jasmonate (JAs) plays an indispensable role in formation many qualities fruit. Therefore, present study aimed explore effect jasmonate on VOCs fruit during storage. During storage, fruits were treated with various concentrations methyl (MeJA) and sodium diethyldithiocarbamate (DIECA, a JAs inhibitor), inhibitors biosynthesis. Subsequently, composition levels determined using GC-MS. The results showed that 100 uM MeJA treatment could promote accumulation while mM DIECA had opposite effect. Meantime, significantly promoted peel degreening, soluble solids content (SSC), softening, ethylene formation. RT-qPCR stimulated expression PuAAT1 repressed PuCXEs, leading increased compounds. Overall, these provide reference for further research aroma.

A 3R-MYB transcription factor is involved in Methyl Jasmonate-Induced disease resistance in Agaricus bisporus and has implications for disease resistance in Arabidopsis

Journal of Advanced Research, Год журнала: 2024, Номер unknown

Опубликована: Сен. 1, 2024

Methyl jasmonate (MeJA) and MYB transcription factors (TFs) play important roles in pathogen resistance several plants, but TFs conjunction with MeJA-induced defense against Pseudomonas tolaasii edible mushrooms remain unknown. To investigate the role of a novel 3R-MYB factor (AbMYB11) disease A. bisporus transgenic Arabidopsis to P. tolaasii. Mushrooms were treated MeJA alone or combination phenylpropanoid pathway inhibitors, effects treatments on disease-related physiological indicators determined assess inducing importance involved. Subcellular localization, gene expression analysis, dual-luciferase reporter assay, electrophoretic mobility shift experiments performed elucidate molecular mechanism AbMYB11 regulating resistance. application greatly improved mushroom infection, suppression significantly weakened this effect. treatment stimulated accumulation metabolites, which was accompanied by increased activities biosynthetic enzymes pathway-related genes (AbPAL1, Ab4CL1, AbC4H1) an AbPR-like gene, further confirming critical responses Importantly, AbMYB11, localized nucleus, rapidly induced under infection; it transcriptionally activated genes, overexpression phenylpropanoid-related total phenolics flavonoids, This study clarified pivotal as regulator modulating pathway, providing idea for breeding highly disease-resistant plants.

Melatonin and methyl jasmonate inhibited the chilling injury of postharvest pitaya fruit after cold storage by regulating the antioxidant system

New Zealand Journal of Crop and Horticultural Science, Год журнала: 2024, Номер unknown, С. 1 - 11

Chilling injury (CI) is the main physiological disease caused shelf decay of pitaya fruit after low-temperature storage. To find ways to control chilling fruit, we conducted effects postharvest treatment with 1.0 mmol L−1 melatonin (MT) and 0.1 methyl jasmonate (MeJA) on vs Zihonglong at 3 days life storage 2 ± 0.5°C. The results showed that both MeJA MT promote accumulation antioxidants reactive oxygen species (ROS) metabolism, inhibit respiration rate ethylene release rate, thereby reducing incidence cold storage, keeping quality prolonging fruit. In summary, or inhibited by regulating antioxidant system.

MeJA inhibits fungal growth and DON toxin production by interfering with the cAMP-PKA signaling pathway in the wheat scab fungus Fusarium graminearum

mBio, Год журнала: 2025, Номер unknown

ABSTRACT Deoxynivalenol (DON), a mycotoxin primarily produced by Fusarium species, is commonly found in cereal grains and poses risks to human animal health, as well global grain trade. This study demonstrates that methyl jasmonate (MeJA), natural plant hormone, inhibits the growth conidiation of graminearum . Importantly, MeJA significantly reduces DON production suppressing TRI gene expression toxisome formation. To explore molecular mechanism, we identified MeJA-tolerant mutants, including transcription factor MRT1 cAMP-PKA pathway-related genes ( FgGPA1 FgSNT1 ). treatment reduced PKA activity intracellular cAMP levels F. , suggesting it targets pathway. Notably, MeJA-resistant mutant R178H enhanced fungal growth, production, presence MeJA. Exogenous alleviated MeJA’s inhibitory effects on further supporting this pathway’s involvement. Interestingly, had no effect all three MAP kinase pathways (Mgv1, Gpmk1, FgHog1). Truncated phospho-mimicking mutations Mrt1 or FgSnt1 conferred resistance, they may act downstream In conclusion, presents promising approach control production. IMPORTANCE (DON) significant both health severely disrupts trade due its prevalence common contaminant wheat grains. With rising public concern over food safety, finding effective sustainable methods reduce contamination becomes increasingly urgent. our study, can effectively inhibit vegetative toxin underlying mutants revealed exerts antifungal activities inhibiting signaling pathway Our work provides solution grains, enhancing safety while decreasing reliance chemical fungicides their associated environmental impact.
