a valuable composition of mentha piperita l. essential oil is menthol that is widely used fordifferent industries. the plants were treated with different concentrations of methyl jasmonate (meja) and after 24 h were evaluated for total soluble proteins, chlorophylls (a, b, and total), malondialdehyde, carbohydrates and antioxidant enzymes (superoxide dismutase and guaiacol peroxidase). variance...

We electrophysiologically investigated the effect of some fragrant compounds in oolong tea on the response of ionotropic gamma-aminobutyric acid (GABA) receptors (GABAA receptors) which were expressed in Xenopus oocytes. Of the tested fragrances in oolong tea, cis-jasmone, jasmine lactone, linalool oxide and methyl jasmonate significantly potentiated the response. Among these, cis-jasmone and m...

The present study was investigated the effects of two elicitors methyl jasmonate (0, 125, 250 and 500 µM) and chitosan (0, 50, 150 and 250 mg L-1) on shoot and callus growth of Iranian Hypericum perforatumL. in vitro cultures in separate experiments. The experiment was done in the base of completely randomized design with five replications and five explants in each replication. Methyl jasmonate...

Gel electrophoretic analysis of the proteinase inhibitor proteins induced in tomato leaves by airborne methyl jasmonate (EE Farmer, CA Ryan [1990] Proc Natl Acad Sci USA 87: 7713-7716) revealed the new appearance of inhibitors I and II and two other, higher molecular mass proteins (63.5 and 87 kilodaltons). Northern analysis of methyl jasmonate-induced inhibitors I and II mRNAs in tomato (Lycop...

an efficient transformation system for the medicinal plant portulaca oleracea was established using agropine-type agrobacterium rhizogenes atcc15834. hairy roots were obtained directly from cotyledon leaves explants seven days after inoculation with the bacteria. the highest transformation efficiency was obtained from cotyledon leaves explants, and amounted to 53.3% within two weeks. roots grew...

The effect of methyl jasmonate on morpho-physiological and biochemical parameters mineral contents in Satureja khuzistanica Jamzad under salinity stress

Methyl jasmonate has a strong effect on secondary metabolizm in plants, by stimulating the biosynthesis a number of phenolic compounds and alkaloids. Common buckwheat (Fagopyrum esculentum Moench) is an important source of biologically active compounds. This research focuses on the detection and quantification of 2-phenylethylamine and its possible metabolites in the cotyledons, hypocotyl and r...
