Jasmonates

Definition

Jasmonates are plant hormones that regulate various aspects of growth, development, and defense responses. They play a crucial role in the plant's ability to respond to environmental stress and herbivory.

5 Must Know Facts For Your Next Test

1. Jasmonates are synthesized from fatty acids in the chloroplast membrane.
2. They are involved in the regulation of gene expression associated with plant defense mechanisms.
3. Jasmonates can inhibit root growth while promoting seed germination and fruit ripening.
4. Upon herbivore attack, jasmonates stimulate the production of secondary metabolites that deter predators.
5. They interact with other plant hormones like ethylene and salicylic acid to coordinate complex defense responses.
