Ethylene the only gaseous plant hormone (C2H4) This is a simple gas that is produced naturally in small quantities by many plant tissues and is able to diffuse readily, via intercellular spaces, throughout the entire plant body. Ethylene is involved primarily in plant responses to environmental stresses such as flooding and drought, and in response to infection, wounding and mechanical pressure. It also influences a wide range of developmental processes, including shoot elongation, flowering, seed germination, fruit ripening and leaf abscission and senescence.
