Abstract

The project is concerned with the chemical and biophysical characterisation of starch isolated from an isogenic set of pea starch mutants. The collection of pea starch mutants allows the action of individual genes to be investigated. The aim is to characterise the architecture of the starch granules and the chemical composition and structure of the starch polysaccharides. Studies on these isogenic lines will allow comparison between groups of mutants in which enzymes involved in the supply of substrate during biosynthesis have been suppressed and also groups which represent reduced activity of enzymes involved in polymer biosynthesis. Studies of alleles at particular loci will allow the effect of the severity of the mutation to be studied. The aim is to identify mutations which alter granule architecture and hence starch functionality, to relate where possible such changes in architecture to changes in chemical composition or structure of the starch polysaccharides, with a view to understanding control of granule structure and functionality at the genetic level. Such data will form a rational basis for manipulation of starch structure and function through the production of double and triple mutants
