Abstract

Recent advances in the study of GA mutants are reviewed. Endogenous GAs in the vast majority of GA synthesis and response mutants have now been quantified by physicochemical means, and the implications of the results are discussed. In recent papers the effects of synthesis mutations on processes other than stem elongation have received increased attention, as has the advent of mutants with reportedly elevated GA levels. The ‘feedback theory’ has been formulated, explaining paradoxical observations on endogenous GA levels in certain response mutants. In a significant breakthrough, a GA biosynthesis gene has been cloned, paving the way for a combined approach to future GA research, involving GA mutants, physicochemical analyses, and molecular techniques.
