These findings, supported by similar results in additional experiments with tobacco and alfalfa plants, demonstrate that methyl jasmonate is quite "powerful in turning on the proteinase inhibitor genes," Farmer says.
He and Ryan went on to show that sagebrush leaves -- which naturally contain methyl jasmonate at concentrations comparable to those used in the dowel experiments -- could elicit the same response.
They showed that methyl jasmonate can directly activate the potato DNA, which normally switches on a proteinase inhibitor gene found in potato leaves, Ryan says.

treated with different concentrations of silver nanoparticles (AgNPs) and Methyl Jasmonate (MeJA).
George Buta showed that methyl jasmonate may reduce chilling injury by regulating levels of abscisic acid and polyamine compounds produced from amino acids that stabilize plant cells.
Buta says that methyl jasmonate elicits compounds in living plants that make them more resistant to temperature changes and attack by insects, bacteria, and fungi.
Produced commercially, methyl jasmonate is relatively inexpensive, and only small amounts are needed to be effective.
Methyl jasmonate (Sigma-Aldrich, Inc) solution was prepared at a concentration of 100 [micro]M in ethanol.
Therefore, cell suspension cultures were elicited on day 21 with methyl jasmonate.
Elicited cell suspension cultures turned dark brown 2 days after the addition of methyl jasmonate while control cultures remained orange-yellow (Figure 5).
