Dissecting the jasmonate singalling pathway in Arabidopsis thaliana
… thesis aimed to further our understanding of jasmonate signalling by identifying specific promoter elements and associated transcription factors important for gene regulation by methyl jasmonate. A cDNA encoding a β-glucosidase, PYK10, was previously isolated using the differential display …

Elucidating the role of jasmonate metabolites in jasmonic acid signaling
… to many derivatives collectively termed as jasmonate (JA). Jasmonoyl-isoleucine (JA-Ile), among the JA is the bioactive form that signals through a nuclear residing co-receptor complex via direct binding to the receptor and subsequent activation of downstream gene expression. Although the JA …

Elucidation of Jasmonate-Responsive Promoter Elements in the Calmodulin-Like Gene CML39 in Arabidopsis
All organisms require rapid and flexible signaling mechanisms in order to effectively respond to biotic and abiotic stress. Calcium ions (Ca2+) have proven to be important components of signaling networks. Observations of stimulus-specific oscillations of cytosolic Ca2+ during signal transduction …

Enhancing human health promoting activity through the regulation of the methyl jasmonate mediated glucosinolate biosynthesis in Brassica oleracea
Brassica oleracea vegetables are recognized as functional foods that contain various phytochemicals such as glucosinolates (GS) and flavonoids that have health-promoting bioactivity. Recent data suggest that methyl jasmonic acid (MeJA) can increase concentrations of GS and polyphenolics in Brassica …

Manipulation of Anthocyanin Accumulation by Vaccinium Pahalae in Vitro
… by cultures treated with exogenous methyl jasmonate (MJ), a signaling compound. The addition of 0.5 muM MJ alone provoked a striking 2.8 fold increase in anthocyanin production over the control, however, no additive effect on anthocyanin production was observed in any treatments which …

Applications of titanium-mediated reductive coupling and cyclocarbonylation reactions toward natural product synthesis
… in particular PGF<sub>2α</sub> and methyl jasmonate. Based on this hetero Pauson-Khand strategy, we have established an efficient racemic route to both the prostaglandin and the methyl jasmonate core skeletons. Moderate to excellent selectivities with regard to the hetero Pauson-Khand …

A Role for Inositol Pyrophosphates in Arabidopsis Defense Against Herbivorous Insects
… as auxin regulation, phosphate (Pi) sensing, and jasmonate-(JA)-regulated plant defense. Transgenic plants that overexpress inositol tetrakisphosphate 1-kinase (ITPK1) and the kinase domain of the dual domain diphosphoinositol pentakisphosphate kinase 2 (VIP2KD) have been previously studied to …

Cyclopentenon-Phytoprostane als Induktoren von pflanzlichen Abwehrreaktionen
… von zyklischen Oxylipinen vom Typ der Jasmonate führen, wohingegen durch freie Radikal-katalysierte Oxidation von alpha-Linolensäure mehrerere Klassen zyklischer Oxylipine, den Phytoprostanen entstehen können. Eine dieser Phytoprostanklassen, Phytoprostane E1 (PPE1), kommen ubiquitär in …

The effects of jasmonates on the proliferation of human prostate cancer cell lines in culture
Jasmonic acid (JA), cis-Jasmone (CJ), and Methyl jasmonate (MJ), belong to a family of plant stress hormones known as the jasmonates. In plants, these compounds function as activators of cellular responses to diverse situations including cell death. Proliferation and cytotoxicity assays showed that …

Metabolite Production in Callus Culture of Burdock (Arctium lappa L.)
… we added different concentrations of methyl jasmonate and sucrose to the culture media and assessed their effects on callus growth and phenolic production. To identify and quantify the phenolic components in burdock callus, we analyzed the phenolic extraction from callus by the …

Development of Novel Anti-microbial Plant Essential-Oil Treatments to Reduce the Postharvest Incidence of Botrytis cinerea of Strawberries
… combination of ethanol (495.5 ppm), methyl jasmonate (4.5 ppm), citral (30 ppm), linalool (30 ppm), and vanillin (30 ppm) was the most effective formula to reduce rot and increase shelf-life overall and strawberries treated with 600 ppm of this blend maintained acceptable organoleptic …

Integrated Multiple-tactic Management of the Redbanded Stink Bug on Soybeans in Louisiana
… Results from this study showed that methyl jasmonate had a significant impact on the number of fire ants collected during a 5-minute time interval. Overall, results from this research provide important information on the integrated pest management (IPM) of P. guildinii and other stink bugs …

Gene expression associated with drought tolerance in Xerophyta viscosa Baker
… supply of abscisic acid, ethylene and methyl jasmonate. Localization studies of the XVDH encoded protein showed that XVDH is located in the plasma membrane-cell wall region.

Improving biomass of the marine microalga Nannochloropsis oculata by chemical elicitation
… autotrophically in the presence of methyl jasmonate (MJ) and salicylic acid (SA) to determine the effects on growth and lipid biosynthesis. Interestingly, 100 μM of MJ added on day 21 of cultivation elicited a 34.3% higher accumulation of lipids than nitrogen starved conditions (0 mg/L …

Dissection of Regulatory Networks Mediating Resistance and Susceptibility of Arabidopsis thaliana to the Downy Mildew Pathogen Hyaloperonospora parasitica
… acid (SA), or components of the ethylene and jasmonate response pathways. Furthermore, RPP7 is not strongly compromised by mutations in genes associated with defense signal transduction (PAD4, NDR1, NPR1, RAR1). Double mutant combinations of these signal transduction components were analyzed …

Diverse functions of the two segmentally duplicated 9-lipoxygenases ZmLOX4 and ZmLOX5 of maize
… Although the physiological functions of jasmonate-producing 13-LOXs in dicots have been reported and highlighted in host defenses to pathogens and insects, the functions of 9-LOXs and 9-LOX derived oxylipins remain obscure for both monocots and dicots. The objective of this study was to …

Combinatorial biochemistry of triterpene saponins in plants
… of triterpene saponin biosynthesis by methyl jasmonate treatment, a genome-wide cDNA-AFLP transcript profiling was carried out for the five plants. Taking into account the putative functional annotation and the expression pattern of the visualized transcript tags, a set of 259 candidate genes …

Elucidating essential roles of oomycee effector proteins in immune suppression and in targeting hormonal pathways in the host plant
… Hpa effector protein, HaRxL10, targets the Jasmonate-Zim Domain (JAZ) proteins that repressed responses to the phytohormone jasmonic acid (JA). This manipulation activates a regulatory cascade that reduces accumulation of a second phytohormone, salicylic acid (SA) and thereby attenuates …
