Abstract

Ideas about the role of sucrose synthase (SuSy) in determining sink strength and carbon partitioning in storage organs will be examined using a new mutant of pea with drastically reduced activity of this enzyme in the developing embryo. Specific attention will be paid to the possibility that the enzyme plays a direct role in cell wall synthesis. The availability of a mutant line in which SuSy activity is apparently impaired in the degradative but not the synthetic direction will allow mechanisms of regulation of the enzyme to be elucidated. The work will provide information of direct relevance to the rational manipulation of the yield and quality of the harvested parts of crops.
