Circadian Organization

Adult Japanese quail have an endogenous circadian clock located in their eyes that has been shown to regulate melatonin biosynthesis. We investigated if a circadian oscillator is present in cultures of dispersed embryonic quail retina. Melatonin release in retinal cell culture is modulated by the light cycle, indicating that there are functional photoreceptors in culture. However, when cultures were placed in constant darkness no rhythm of melatonin was observed, indicating that at this period of development the circadian oscillator does not influence melatonin release. To explore further the question of whether a circadian oscillator is present in embryonic cell culture, we examined expression of iodopsin, the red visual pigment. Iodopsin mRNA is expressed in a circadian rhythm with peak levels occurring late in the afternoon (ZT 9). Analysis indicates that the clock influence is at the level of gene transcription. These results suggest that a clock is not “hooked up” to melatonin release embryonically or that a different oscillator regulates photopigment expression versus melatonin release.

Vergleichende Untersuchungen

Abstract Comparative studies on the essential oil of the whole plant and callus-and suspension cultures of Pimpinella anisum L. were carried out. Both the whole organism and the cell cultures were shown for the first time to be similar in their constituents e.g. anethole, pseudoisoeugenol-(2-methyl-butyrate), epoxy-pseudoisoeugenol-(2-methyl-butyrate) and β-bisabolene. In difference to the plant, the callus-culture contained myristicine.
