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.
The most common type, systemic lupus erythematosus, affects many parts of the body. Other types of lupus are: 1  Discoid lupus erythematosusâcauses a skin rash that doesn't go away. 2  Subacute cutaneous lupus erythematosusâcauses skin sores on parts of the body exposed to sun.he most common type, systemic lupus erythematosus, affects many parts of the body.

There are many kinds of lupus. The most common type is systemic lupus erythematosus (SLE), which affects many internal organs in the body. SLE most often harms the heart, joints, skin, lungs, blood vessels, liver, kidneys, and nervous system.oting that many people with lupus had a disease that not only affected the skin but many other organs in the body as well, Osler added the word systemic to the term lupus erythematosus to distinguish this type of disease from discoid lupus erythematosus.
