title: The in vitro induction of puffing in salivary glands of the mutantl (2)gl ofDrosophila melanogaster by ecdysone.
abstract: Salivary glands of 9-10 day oldlethal giant larvae (l(2)gl, 2-0.0) respond to culture with ecdysone in a similar manner to mid third instar glands from wild type larvae. In particular, the ecdysone dependent puffs characteristic of pupariation, not previously observed in this mutant, are immediately induced. The secretion of the stored 'glue' granules into the lumen of the salivary glands is also induced by ecdysone inl(2)gl.
