Abstract

The initial step of starch degradation is not known in most plant organs. Glucan water dikinase (GWD) - an enzyme that phosphorylates starch - is necessary for this step. By analysing GWD function in Arabidopsis leaves we aim to discover the enzyme(s) responsible for the initiation of starch degradation, and the way in which degradation is controlled. We will study the relationship between GWD, starch phosphate levels and rates of starch synthesis and degradation. Approaches include 1) analysing transgenic plants with altered GWD levels, 2) studying the impact of other mutations on degradation in plants lacking GWD, 3) purifying GWD-binding proteins. The results are relevant to manipulation of starch content in crops and production of novel starches. (Joint with BBS/B/11877).
