Das circadiane Uhrnetzwerk ausgewählter Insekten
Zusammenfassung
Eine wichtige Voraussetzung zum Verständnis des täglichen “Timing” von Insekten ist die funktionelle Charakterisierung des neuronalen Uhrennetzwerks im Gehirn. Wir werden zu diesem Verständnis beitragen, indem wir das Uhrennetzwerk von verschiedenen Drosophila-Arten mit sequenzierten Genomen und mit unterschiedlichen Lebensräumen (z.B. Vorkommen an verschiedenen Breitengraden und auf verschiedenen Meereshöhen) aufklären. Zusätzlich werden wir beginnen die Innere Uhr von selektierten Hymenopterenarten und von verschiedenen Blattlaus-Morphen auf molekularer und neuronaler Ebene zu erforschen. Dabei handelt es sich um Arten, die in den Bereichen B und C untersucht werden.
