jasmonate

Examples of jasmonate in the following topics:

• Plant Responses to Wind and Touch

  • Application of jasmonic acid is sufficient to trigger tendril coiling without a mechanical stimulus.
  • Ethylene and jasmonate are likely involved in thigmomorphogenesis.

• Plant Defenses Against Herbivores

  • As tissue is damaged, jasmonates may promote the synthesis of compounds that are toxic to predators.
  • Jasmonates also elicit the synthesis of volatile compounds that attract parasitoids: insects that spend their developing stages in or on another insect, eventually killing their host.

• Abscisic Acid, Ethylene, and Nontraditional Hormones

  • Jasmonates play a major role in defense responses to herbivory.
  • For example, chewing of tomato plants by caterpillars leads to an increase in jasmonic acid levels, which in turn triggers the release of volatile compounds that attract predators of the pest.
