Q. Ethylene gas is a plant hormone that regulates plant growth, development and response to environmental stress. It is produced from leaves, roots, stems, flowers and fruits, and it plays a major role in fruit ripening, flowering and abscission (the natural shedding of leaves, flowers and fruits). Like all hormones, ethylene functions via an intracellular signal transduction pathway, which is illustrated in Figure 1 above.
