The elongating leaves of young rye seedlings do not show a gravitropic response when placed horizontally. However, after treatment with ethylene, either supplied exogenously via ethephon or by application of its precursor 1-aminocyclopropane-1-carboxylic acid (ACC), gravicompetence is seen. The inhibition of ethylene perception by 1-methylcyclopropene (MCP) prevents gravicompetence. Young rye leaves provide a useful model system in which to identify the components of the gravity sensing or response systems, the presence of which govern gravicompetence.

Key words: Key words: ACC, coleoptiles, ethephon, ethylene, gravicompetence, gravitropism, primary shoots, rye, Secale cereale.
