We have previously shown that cycloheximide resistance can be induced in a strain of Candida maltosa by modifying ribosomes (M. Takagi, S. Kawai, Y. Takata, N. Tanaka, M. Sunairi, M. Miyazaki, and K. Yano, J. Gen. Appl. Microbiol. 31:267-275, 1985). The present paper describes the cloning of the gene involved in this resistance (designated RIM-C for ribosome modification by cycloheximide) by us...
Promitochondria of anaerobically grown Saccharomyces cerevisiae were selectively labeled in vivo by incubating the cells with [(3)H]leucine and cycloheximide. When the labeled cells were washed free of cycloheximide and adapted to oxygen in the presence of unlabeled leucine, the respiring mitochondria formed during adaptation proved to be radioactive. In contrast, only insignificant label was f...
Cycloheximide inhibits polar indoleacetic acid transport in midrib tissues of leaves of citrus (Citrus sinensis [L.] Osbeck) and poplar (Populus deltoides Bartr.) as measured by the donor-receiver agar cylinder technique. It appears that the mechanism of auxin transport inhibition by cycloheximide consists in arresting protein synthesis and not in the disruption of energy flow. The interpretati...
Application of eucaryote inhibitors to the estimation of production and grazing mortality of bacterioplankton was evaluated. Exposure to a range of concentrations of thiram, cycloheximide, and neutral red (0.4 to 210, 36 to 1,777, 4 to 346 ,uM, respectively) was 98 to 100% effective at inhibiting growth of a chrysomonad in culture. Exposure to colchicine and griseofulvin (50 to 1,000 ,uM for bo...
The change in the amount of immunoreactive oxytocin in human term placental tissue due to cycloheximide, an inhibitory agent of protein biosynthesis, was observed by a tissue culture method. The immunoreactive oxytocin content per gram tissue was 1.81 ng/g and significantly decreased to 1.17-1.11 ng/g when the concentrations of cycloheximide were at 1-10 micrograms/ml in culture medium. The tot...
l-Leucine-U-(14)C was incorporated into mitochondrial protein in pea (Pisum sativum var. Alaska) cotyledons during the imbibing stages. Incorporation was almost completely inhibited by cycloheximide but not by chloramphenicol. Both antibiotics did not affect increases in mitochondrial activities and components of the cotyledons during imbibition. Therefore, mitochondrial development seems to be...
A single injection of 1.5 mg/kg of cycloheximide induces a complete disappearance of mitotic activity in rat intestinal crypts within 1.5-2 hr. No significant necrosis of crypt cells is observed even though this phenomenon is accompanied by a marked decrease in uptake of labeled precursors into protein and DNA. Mitoses reappear 6 hr after injection and recovery then follows a cyclic pattern ove...
Cycloheximide is frequently presumed to inhibit specifically the cytoplasmic protein synthesis of eukaryotes. Although previous investigators have shown that it had other effects on the cells of a variety of organisms, these results were frequently presumed to be secondary effects of the inhibition of protein synthesis. This paper shows that a wide range of deleterious effects are produced by c...
