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.
摘要
9至10日龄致死性巨型幼虫（l(2)gl, 2-0.0）的唾液腺对蜕皮激素培养的反应，与野生型幼虫三龄中期腺体的反应方式相似。特别是，此前在该突变体中未观察到的、依赖蜕皮激素的化蛹特征性胀泡会立即被诱导。在l(2)gl中，蜕皮激素也会诱导储存的“胶水”颗粒分泌到唾液腺管腔中。
