Název v původním jazyce

The release of a pheromonotropic neuropeptide, PBAN, in the turnip moth Agrotis segetum, exhibits a circadian rhythm

Popis výsledku v původním jazyce

In the female turnip moth, Agrotis segetum, a Pheromone biosynthesis activating neuropeptide (PBAN) stimulates sex pheromone biosynthesis which exhibits a daily rhythm. Here we show data supporting a circadian rhythm in PBAN release from the corpora cardiaca, which we propose regulates the endogenous rhythm in sex pheromone biosynthesis. This conclusion is drawn as the observed daily rhythm in PBAN-like immunoreactivity (PBAN-ir) in the hemolymph is persistent in constant darkness and is phase- shiftedby an advanced light: dark cycle. PBAN-ir was found in the brain, the optic lobe, the suboesophageal ganglion and in the retrocerebral complex. In each hemisphere ca 10 immunopositive neurons were observed in the pars intercerebralis and a pair of stained somata in the dorso-lateral protocerebrum. A cluster of cells containing PBAN-ir material was found in the tritocerebrum and three clusters of such cells were found in the SOG. Their processes reach the corpora cardiaca.
