Abstract
Shoot branching is an important agronomic trait and its regulation provides an excellent system in which to study the role of phytohormones in the control of plant development. Apically-derived auxin can inhibit the growth of lateral shoots, but it does not act directly in the axillary buds. This project aims to test the model that auxin acts in the stem and roots through regulating the production of a second messenger that relays the auxin signal into the buds. We propose that signalling via this second messenger is mediated by a newly defined group of genes, the MAX genes, that we have identified because their loss of function results in a bushy morphology and auxin resistant buds. We propose to test aspects of this model and hence to gain a better understanding of the mechanism of auxin action in the control of shoot branching.
