[The influence of inhibitors of protein synthesis on the secretion of the carbohydratous trapping slime of Drosophyllum lusitanicum].

The secretion of the carbohydratous trapping slime of Drosophyllum is known to be mediated by the Golgi apparatus. In order to determine whether this secretion depends on the synthesis of new membrane material or runs for a long time by the cycling of membrane molecules, the influence of several inhibitors of protein synthesis was studied. Cycloheximide decreases the secretion of polysaccharides drastically, whereas puromycin and the amino acid analogues fluorophenylalanine and ethionine have little or no influence. An attempt is made to find explanations for these results, which, although contradictory, have parallels in the literature.
