Abstract
The review contains four sections; 1) starch granule-bound UDP-glucose starch glucosyl transferase deficiency in waxy maize, 2) the proportionality of bound transferase activity with number of Wx alleles for the endosperm and a comparison of transferase from embryo and endosperm, 3) ADP-glucose pyrophosphorylase dificiency in shrunken-2 and brittle-2 mutants, 4) phosphorylase I, II, and III in maize endosperm. These investigations reported in this review emphasize our limited knowledge of how starch synthesis really proceeds in the endosperm of maize. At the same time, they illustrate how useful the mutant data may be in contributing to an ultimate solution.
