knockout mutant plants lacking Apx1 show high sensitivity to wounding and methyl jasmonate treatment. In the leaves of wild-type plants, H2O2 accumulates only in the vicinity of the wound, while in the leaves of the knockout mutant plants it accumulates extensively from damaged to undamaged regions. During methyl jasmonate treatment, the levels of H2O2 are much higher in the leaves of Apx1 knockout plants
0.02 mM methyl jasmonate increases the activity of the enzyme to 148%. 0.2 mM and 1.0 mM methyl jasmonate increases enzyme activity by 46% and 47%, while 0.05 mM induces a smaller elevation of activity by 21% in tomato fruits
spraying exogenous plant hormone methyl jasmonate upon radish sprout decreases the activity of myrosinase and the amount of 4-methylthio-3-butenylisothiocyanate but increases the total phenolic content which results in increased 2,2-diphenyl-1-picrylhydrazyl free radical scavenging capacity
Differential responses of anti-oxidants enzymes, lipoxygenase activity, ascorbate content and the production of saponins in tissue cultured root of mountain Panax ginseng C.A. Mayer and Panax quinquefolium L. in bioreactor subjected to methyl jasmonate stress.
Synergistic effects of sequential treatment with methyl jasmonate, salicylic acid and yeast extract on benzophenanthridine alkaloid accumulation and protein expression in Eschscholtzia californica suspension cultures
