Jasmonic acid (JA)is a hormone produced in plants that is made as a defensive response to necrotrophic pathogens, or pathogens that kill the host plant and consume the dead matter. JA also stimulates an induction of anti-herbviroy responses. The anti-herbivory chemicals can only be produced in the presence of a wound, likely after an insect or animal starts eating. Jasmonic acid is transported through plant vasculature, but it can also act locally, meaning that where the wound is will also produce anti-herbivory chemicals. Perception of JA is through the COI1 receptor, which is located inside the cell. JA also stimulates the production of volatile signaling compounds, which can then prime other tissues and plants for attack by making them unpalatable, or poor-tasting. These volatiles are recognized by the insects or animals that eat them and turn them away from consuming the plant further.

Consider that the first sentence of a paragraph should be a strong statement topic sentence. Consider revising the topic sentence here to be more concise. It may be able to be made into two separate sentences.

In the begining when first introducung anti-herbivory responses you could give a few examples of anti-herbivory respones so the read has an idea where the rest of the paragraph is going to go.
