Green Leaf Volatiles (GLVs)

For the first time, scientists were able to visualise plants sensing compounds released by other plants in danger.

GLV – A group of compounds that a plant releases into the air when it is injured which may be a warning to other plants that danger is near.
They consist of six carbon (C6) compounds including alcohols, aldehydes and esters which are released from almost every plant.
2 major defence mechanisms
- When a plant is damaged, GLVs are released as by-products. Plants can make themselves less palatable or even indigestible to the insect attackers.
- When an insect takes a bite of a plant leaf, calcium ions flood the leaves in the cells.
- Future prospects – To fight agricultural pests without using pesticides and going organic.

Other internal defence responses of plants - Jasmonic acid activates plants’ defences and effectively repels insect pests.
