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.

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.

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.

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.

Postharvest decay, primarily occurring after ripening, leads to substantial losses. Ripening increases tomato susceptibility Botrytis cinerea, linked desensitization of jasmonate (JA) biosynthesis and defense signaling. During key JA genes such as allene oxide synthase (AOS) 12-oxophytodienoate reductase 3 (OPR3) were downregulated in response wounding or fungal challenges. The Slmyc2 mutants with impaired responses showed heightened pathogen sensitivity. Conversely, EIN3-Like sleil1 exhibited elevated SlMYC2 levels, which increased expression lipoxygenase D (LOXD), OPR3, AOS, cyclase (AOC) alongside including proteinase inhibitor PI-6, PI-27, polyphenol oxidase, pathogenesis-related proteins, thereby enhancing resistance. Treatment DNA methyltransferase 5-azacytidine content, suggesting epigenetic regulation JA-mediated defense. Collectively, intensified ethylene signaling during mediated by SlEIL1, suppressed JA-dependent against B. highlighting ethylene-JA antagonism a driver postharvest decay.
