Salivary glands implanted in adult milieu without simultaneous implantation of larval ring glands showed further development and differentiation. The development of the glands was tested by thymidine-H3 and uridine-H3 incorporation in the chromosomes

In Drosophila hydei abnormal puffing activities could be induced by temperature shocks and treatments with 1.2% and 1.4% KCl solutions. After temperature shocks in vivo and in vitro, a number of puffs showed a similar change in activity.

The effect of injection of various concentrations (4 ng to 0.5 μg/larva) of α-amanitin on chromosomal RNA synthesis in larval salivary glands of D. hydei was investigated at subsequent time intervals (90 min to 20 hrs) after injection. — As revea

Relative values for the dry mass in puff-forming regions of Drosophila hydei salivary gland chromosomes were established with a Leitz double beam interference microscope. All measurements were made after RNA digestion. Optical path differences per un

Funf Stunden nach Injektion von 0.5 μg α-Amanitin in Larven des III. Stadiums vonDrosophila hydei zeigen viele Nukleolen der Speicheldrusenzellen eine Fragmentierung und die meisten eine erhohte Markierung mit3H-Uridin. In Tieren, die mit α-Amanit
