Many agronomically important crops are viewed as significant resources of renewable energy. Overall crop productivity could be increased if the efficiency of photoassimilate conversion into dry matter such as starch were improved in storage tissues. Starch production is controlled by the catalytic activity of ADPglucose pyrophosphorylase in the first step of starch biosynthesis. This research focuses on the genetic structure and molecular mechanisms by which it is controlled during plant development and how it is affected by environmental and hormonal conditions. The current goal is to isolate the genes for this enzyme present in both cereal endosperm and potato tuber tissues, and to elucidate its structure and the controlling sequences responsible for gene expression. The long term goal is the improvement of starch production in storage organs by manipulating this gene so that it encodes an enzyme refractive to inorganic phosphate inhibition.
