Abstract

The R1 protein is responsible for the phosphorylation of glucosyl residues in the amylopectin fraction of starch, during starch synthesis. Mutant and transgenic plants lacking the R1 protein not only lack phosphate groups in the starch but also have much-reduced rates of starch degradation. This suggests that the phosphate groups and/or the R1 protein itself play an important role in starch degradation, but the nature of this role is not understood. In this project we aim to discover the role of R1 in starch degradation. Main approaches will be to create plants in which expression of the R1 gene can be changed rapidly by use of an inducer, and to isolate and characterise proteins with which R1 interacts in vivo.
