 Title    in Saccharomyces cerevisiae  
 Abstract    The ribosomal ribonuclease of yeast is induced after a withdrawal of glucose. Cycloheximide inhibits the synthesis of the enzyme under conditions of induction but antimycin shows no effect. Hence, the increase of the ribonuclease activity during growth of yeast is due to newly synthesized enzyme, and the induction does not depend on respiration.

 Title    Transport and Processing of Ribosomal R N A in Plant Cells after Treatment with Cycloheximide  
 Abstract    In freely suspended cells of parsley (P etroselin u m crispu m) protein synthesis is inhibited nearly totally by 5 /ug/m l cycloheximide within 10 min. This very low dose has a slight effect on the rRNA synthesis too. During an incubation period of 60 min with [32P] orthophosphate in the presence of the inhibitor (5 /ugjml) at least 65 — 70% mature rRNA are synthesized compared with the control. After 120 min the synthesis is progressively reduced to 60 — 65%, and after 240 min to 30-40% . Cycloheximide causes a delay of the processing of the precursor RNA species leading to an accumulation of these components. In addition to the 2.3 x 10® daltons RNA, normally detectable in pulse experiments, two further precursor molecules do emerge which under normal circumstances apparently are shortlived. Their molecular weights are 2.0 x 10® and 0.9 x 10® daltons. The pulse-chase technique and cell fractionation into nuclear and ribosomal parts enables us to demonstrate a rapid transfer of labelled 18S and 25S RNA during a 15 min chase treatment to the mature cytoplasmic ribosomes. Under these conditions no differential transport of the two com­ ponents takes place. The cells possess a pool of proteins. Therefore the formation of RNP-particles or ribosomes respectively and the transport from the nucleus to the cytoplasm are independent from protein synthesis for some time.

 Title    Effects of Pharmacological Agents on Ecdysteroid Synthesis in vitro in Ovaries and Abdominal Integument from Female Adult Crickets, Gryllus bimaculatus de Geer (Ensifera, Gryllidae)  
 Abstract    In fem ale adults of G ryllus bimaculatus, ovaries as well as the abdominal integument pro­ duce free and conjugated ecdysteroids in vitro (Hoffmann et al., 1992). The aim of the current study was to determine the influence of various potential ecdysteroid biosynthesis effectors (RH 5849, KK 42, diflubenzuron, ketoconazole, azadirachtin, acetylenic and allenic
