Phytoglycogen-branching enzyme has been found in du however, no phytoglycogen was isolated by Black et al.23 Preiss and Boyer396 reported that the du mutation lowered starch synthase II activity and also lowered branching enzyme Ha activity. Gao et al.397 used a molecular approach to clone the du gene in maize endosperms and, based on amino acid sequence similarity of the predicted protein product with the soluble starch synthase III of potato,398 concluded that du most likely encodes the 180 000 molecular weight, primer-dependent soluble starch synthase described previously.399,400,401... 

Three forms of branching enzyme from developing hexaploid wheat (Triticum aestivum) endosperm have been partially purified and characterized.260 Two forms are immunologically related to maize BEI and one form to maize BEII. The N-terminal sequences are consistent with these relationships. The wheat BEIb gene is located on chromosome 7B, while the wheat BEIad peptide genes are located on chromosomes 7 A and 7D. The BE classes in wheat are differentially expressed during endosperm development. BEII is constitutively expressed throughout the whole cycle, while BEIb and BEIad are only expressed in late endosperm development.
