Pan and Nelson (1984) first reported that the sugary-1 phenotype is caused by the loss of the activity of a pullulanase-type starch debranching enzyme, suggesting that the debranching enzyme is also involved in starch biosynthesis.he present investigation has been carried out to examine the relationship between the activities of starch debranching enzymes and the alteration of amylopectin structure in various sugary-1 endosperms of rice by partitioning the endosperm into the starch region and the phytoglycogen region.
