Genetic Analysis of Gibberellin Signal Transduction.

In recent years exciting progress has been made in understanding how endogenous plant hormones control plant development. One of the fundamental questions in this area of research is the mechanism by which the presente of a plant hormone molecule (the signal) leads to a change in plant development (the transduction pathway). This Update will discuss progress in the genetic analysis of signal transduction for the class of plant hormones collectively known as GAs. More extensive reviews on various aspects of GA research can be found in Hooley (1994), Ross (1994), and Sponsel (1995).
