Ethylene's role in the shade avoidance response in tobacco plants is related to its role in fruit ripening,leaf abscission,and senescence.

Question

Quizplus · Accepted Answer

This statement is false. While ethylene does play a role in fruit ripening, leaf abscission, and senescence, its role in the shade avoidance response in plants is separate and distinct. In shade conditions, increased levels of auxin promote elongation of stems and leaves to reach for more light, while ethylene mediates the response by inhibiting this elongation and promoting thicker stems and earlier flowering.
