Abstract

Light signals play a crucial role in determining the architecture of individual plants and canopies. In dense stands of plants, reflected FR light signals lead to reductons in R:FR ratio, which are perceived by the phytochromes. Reductions in R:FR ratio trigger shade avoidance reactions, resulting in excessive elongation of internodes and petioles with a concomitant reduction in allocation of resources to harvestable components such as seeds, roots or tubers. We propose to develop a novel strategy for the elimination of shade avoidance elongation growth responses. This will involve using promoter sequences that are responsive R:FR ratio to drive expression of `dwarfing' genes in stems. As a first step, we propose to identify genes that are differentially expressed in stem tissues in response to R:FR ratio signals, isolate the likely promoter sequences of such genes and assess their ability to drive proximity-dependent transgene expression.
