❖ Recently, for the first time, scientists visualise the plants sensing compounds called green leaf volatiles (GLVs) released by other plants in danger.

❖ The Plants have two major defence mechanisms, involving a chain of molecular reactions.

❖ The reactions are triggered when a plant is damaged and GLVs are released as by-products.

❖ The Scientists are considering harnessing this process to fight agricultural pests without having to use pesticides.

❖ Volatiles are elements or compounds that change from solid or liquid state into vapour at relatively low temperatures
