Molecular Approaches to the Study of the Mechanism of Action of Auxins

  • Chapter
Plant Hormones

Abstract

Phytohormones play a crucial role in normal plant growth, but despite their fundamental influence on almost all aspects of plant development, very little is known on their mode of action at the molecular level. Here we describe three different approaches to addressing this question: the analysis of proteins which bind auxin with high specificity and as such might act as auxin receptors; the study of the effect of expression of bacterial genes whose products modify the intracellular levels of auxins and cytokinins, and the generation of gene tagged plant mutants altered in their response to auxins. While diverse in their approach, these strategies have been devised to dissect the auxin signal transduction pathway at the molecular level. The results that we will describe, while sharing a common thread, indicate that the plant cell has evolved a remarkable array of molecular pathways in response to plant growth substances.
