✦ Synopsis

Twelve cDNAs corresponding to m R N A s inducible by ethylene were isolated by differential screening of a c D N A library from ethylene-treated Citrus sinensis fruits. Northern analysis of R N A extracted from flavedo of ethylene-treated fruits and from fruits at different maturation stages showed that some of the mRNAs corresponding to these cDNAs were regulated both by ethylene treatment and during fruit maturation. The effect of exogenous ethylene on leaves and of endogenous ethylene on flowers showed that gene induction was not restricted to the flavedo tissue. The possible role of ethylene during maturation of the non-climacteric Citrus fruit is discussed.
