The solitary bee Rediviva longimanus

is endemic to the Greater Cape Floristic Region. With the elongated forelegs it collects floral oil from the spurs of its host plants of the genus Diascia. By courtesy of Michael Kuhlmann.

A Transgenic Hydra

expressing GFP in the head. The Hydra Transgenic Facility allows us to explore the function of different genes and proteins in vivo in a traditional developmental model. By courtesy of Thomas Bosch.

Floral oil producing Diascia floribunda

has long twin spurs that coevolved with the front legs of their oil-collecting bee pollinators. By courtesy of Michael Kuhlmann.

The common starfish Asterias rubens

climbing a seagrass leave in the Baltic Sea in search of recently settled blue mussels as prey. By courtesy of Thorsten Reusch.

Confocal laser scanning microscopy image

of the fungal pathogen Zymoseptoria tritici (in green) during the infection of a wheat leaf. The hyphae of Z. tritici is visible in green. The tip of the hyphae (in the back) is penetrating an open stoma on the leaf surface. By courtesy of Janine Haueisen, Stukenbrock group.

A sea anemone from the Mediterranean (Anemonia sulcata)

Symbiontic algae are responsible for the purple colour of the tips of the tentacles. By courtesy of Thorsten Reusch.

The fluorescent dye DAPI

is commonly used to stain the DNA in the nuclei of Caenorhabditis elegans body cells, thus visualizing the nematode’s anatomy. By courtesy of Hinrich Schulenburg

Mouse testicular cell spreads.

Mice have 19 Autosome pairs and two sex chromosomes. The DNA is stained using DAPI in blue. Synaptonemal Complex Protein syp3 is stained in green using syp3 primary and Alexa-Flour-488 secondary antobodies. By courtesy of Alina Jeschke, Odenthal-Hesse group.

CRC 1182 Origin and Function of Metaorganisms

Animals and plants alike are colonized by a huge diversity of microbial organisms, forming complex associations, in which the fitness, development, and behaviour of either partner, host or microbe, strongly depends on its interplay with the other.
