Quizplus · Accepted Answer

Abscisic acid (ABA) is known as the stress hormone and is produced in plants when there is a water deficit. It triggers a suite of drought responses such as closing the stomata to prevent water loss and slowing down growth to conserve resources. Therefore, ABA is the most likely hormone produced by the plant discovered by the desert plant research team.
