Abstract
Understanding the factors that regulate lateral branching in plants is critical to modern precision farming processes. This proposal will exploit the experimental benefits of Arabidopsis to identify the genetic and hormonal factors controlling lateral root development. Adopting a quantitative genetic approach would allow the number, relative importance and chromosomal location of the quantitative trait loci (QTL) regulating lateral root number to be determined. The plant hormones auxin and cytokinin represent key regulators of lateral root development; determining the role of auxin as a positional signal and the relative importance of root versus shoot auxin sources represents a major objective. Co-localisation of QTLs regulating lateral root number and root tip IAA would provide strong genetic evidence to support a functional relationship.
