This Module is open for advanced Bachelor and for Master Students and identical to our well known Roscoff Excursion

In the accompanying seminar, we teach basic knowledge of marine biology. The seminar takes place partly at the Marine Biology Station in Roscoff (Brittany). There we study the fauna of marine hard and soft bottoms, rocky mudflats and sand coral reefs. We collect and identify marine organisms and carry out classic sea urchin and sea squirts fertilisation experiments. We observe the early development of sea urchins and sea squirts live. In addition, physiological and molecular/biochemical experiments are carried out, e.g. protein isolation, electrophoresis, PCR and sequencing for species identification. We even take our own fluorescence microscope to France for immunofluorescednce experiments. The Roscoff module will be supervised by Dr Maik Drechsler, Maren Janz, Prof Dr Günter Purschke and Prof Dr Achim Paululat.

The module will take place at the Marine Biological Station in Roscoff, Brittany (FR). Date: 18.05 - 28.05.2025

Master-Modul "Developmental Genetics"

Audience: Master-Students only

LECTURE: The module will focus on the molecular and cellular mechanisms of Drosophila melanogaster development. We discuss morphogen gradients, axis formation, segmentation, and organ formation, among other topics. SEMINAR: Presentations on topics in developmental biology. EXPERIMENTS: We will perform experiments including the following: Expression of proteins in insect cells, analysis by western blot, analysis of subcellular markers in transgenic Drosophila lines by microscopy, localization of transposon insertions in the genome by PCR, in situ hybridization to detect gene-specific mRNAs in tissues, ectopic expression of subcellular markers with Gal4 driver lines, immunohistochemical detection of expression of reporter genes, introduction to fluorescence microscopy and photo documentation. Responsible: Prof. Dr. Achim Paululat, Dr. Maik Drechsler and Priv. Doz. Dr. Heiko Harten

Drosophila embryos, stained for proteins involved in axis formation, segmentation and neural development. Antibody staining.

Ectopic expression of the Eyeless transcription factor in the antenna or leg induces extra eyes. We will study such flies using an scanning transmission electron microscope.

Release of Fluorescein into the inhalant siphon of Ciona intestinalis. The dye passes the pharyngeal basket and exists the anmal via the exhalant siphon. The animals feed by filtering sea water. Movie made during one of our field trips.
