In the larval fat body of Drosophila gibberosa, polytene chromosome structure and activity exhibit cytological differences from chromosomes of midgut and salivary glands. These differences include long-persisting puffs, transient puffs and long-persisting band modulations. Some early ecdysteroid-induced puffs are present in all three organs but few late puffs are present in the fat body. Comparative studies reveal, therefore, that late larval-early pupal puffing is enhanced in salivary glands relative to gut. fat body and Malpighian tubules. After the fat body breaks up in the prepupa, the rate of programmed cell death and the corresponding slow decline of chromosomal activity also differ from cell to cell and from other organs.
