When an herbivore chews on plant tissue, molecules called _______ are formed. These molecules bind to a _______ in the plasma membrane of a _______ cell and initiate the formation of jasmonates. Jasmonate in turn binds to an inhibitor, releasing a transcription factor, which enters the nucleus, turning on genes that code for _______ and other substances important for plant defense.

Question

Quizplus · Accepted Answer

Elicitors are molecules formed when an herbivore chews on plant tissue. They bind to a receptor in the plasma membrane of a companion cell, initiating the formation of jasmonates. Jasmonates then release a transcription factor that turns on genes coding for protease inhibitors and other defense substances.
