_____ is produced in an area of herbivore damage, then it is transported through the phloem to an undamaged area, where it induces transcription of defensive genes.

Question

Quizplus · Accepted Answer

Jasmonic acid is involved in plant defense mechanisms. When a part of a plant is damaged by herbivores, jasmonic acid is produced at the site of injury. It then travels through the plant's phloem to other parts of the plant, where it triggers the transcription of genes responsible for producing compounds that help defend the plant against further damage.
