Transitory and storage starch metabolism: two sides of the same coin?

The industrially important polymer, starch, is manufactured through a complex process involving multiple isoforms of several different enzymes. These contribute to alter the structure of starch which, in turn, affects its downstream industrial use. This review compares recent advances in our knowledge of starch metabolism in leaves and storage organs. Starch granule initiation and formation, enzyme complexes involved in starch metabolism and control of flux in starch synthesis and degradation are examined
