Application

Ethephon (2-Chloroethylphosphonic acid), a widely used plant growth regulator that induces scenescence and fruiting may be used to study its properties as a plant growth regulator, phosphorylating agent and as a butyrylcholinesterase inhibitor. Ethephon may be used as a reference compound in procedures designed to detect ethephon in biological materials.

Ethephon [(2-chloroethyl)phosphonic acid] has two seemingly unrelated types of biological activity. It is a major agrochemical absorbed by crops, slowly releasing ethylene as a plant growth regulator. Ethephon also inhibits the activity of plasma butyrylcholinesterase (BuChE) in humans, dogs, rats...

Rice (Oryza sativa) plants carrying the Pi-i resistance gene to blast fungus Magnaporthe oryzae restrict invaded fungus in infected tissue via hypersensitive reaction or response (HR), which is accompanied by rapid ethylene production and formation of small HR lesions. Ethylene...
