How do plants produce ethylene

WebApr 28, 2006 · When plants are subject to a variety of stresses they often exhibit symptoms of exposure to ethylene. Although this relationship usually results from induction of ACC synthase thus raising the concentration of the precursor of ethylene, it is now apparent that there are numerous other ways that stresses produce ethylene-like symptoms. WebNov 30, 2024 · Plants naturally produce ethylene at the proper time and amounts for root elongation, shoot extension, fruit ripening, and programmed leaf death. However, upon waterlogging and flooding, soils accumulate ethylene produced by microbes. This ethylene can accumulate to levels harmful to plants, leading to crop damage.
