Genetics of Eukaryotic Microorganisms
First joint meeting of GfG „Gen AG Pilzgenetik“ and VAAM special group „Biology and Biotechnology of fungi“
From 19.-21. of September 2019 there was the first joint meeting of the German Society of Genetics group „Gen AG Pilzgenetik“ and the Association for General and Applied Microbiology special group „Biology and Biotechnology of fungi“ hold at the University of Göttingen. Besides eight international plenary speakers, 22 young scientist were chosen from the submitted abstracts to present their current research in oral presentations. Research topics ranged from genetics of fungi, to cell biology and biotechnology. From a total of 88 presented posters, six were chosen for poster awards donated by the GfG.
Reports about the first joint meeting:
„Biology and Biotechnology of fungi“ (Biospektrum 07.19)

Posteraward to Dr. Daniela Nordzieke - Fungal Genetics Conference, USA
The most important conference for fungal geneticist, the 30th Fungal Genetics Conference took place recently at Pacific Grove, USA. Our group presented current research projects dealing with autophagy in Sordaria macrospora as well as zea mays interaction with Colletotrichum graminicola. Both projects were presented orally in the concurrent sessions 'Multicellular development' and 'The fungal spore: development, dormancy and germination' by Stefanie Pöggeler and Daniela Nordzieke, respectively. The highlight of the conference was the awarding of the Postdoc posterprize in the category 'Mutual and pathogenic plant-interactions' to Daniela Nordzieke. Congratulations!
Research - Sordaria macrospora and Colletotrichum graminicola
Filamentous fungi are great model organisms to study fundamental processes in eukaryotes as well as plant pathogen interactions. Our group focuses on both aspects of fungal life, investigating autophagy and multicellular development in Sordaria macrospora and Colletotrichum graminicola interaction with its host zea mays.
Fruiting-body development in filamentous ascomycetes is a complex cellular differentiation process that requires special environmental conditions and is controlled by many developmentally regulated genes. We are interested in the genes regulating this development process. We use the homothallic (self-fertile) ascomycete Sordaria macrospora as a model organism. Since S. macrospora is able to complete the sexual cycle without a mating partner, recessive mutations affecting fruiting body development are directly visible. Numerous mutants which are blocked at various stages of fruiting-body development have been generated and molecular genetic procedures have been applied to isolate genes involved in fruiting-body. more...
Cellular communication processes within a fungal colony or in host-pathogen interactions are crucial to allow adequate development or host infection. We use the hemibiotrophic maize pathogen Colletotrichum graminicola to study both communication types with special emphasis on redox signaling. Reactive oxygen species-generating NADPH oxidases are crucial for communication-related processes like germling fusion, sexual development, chemotropic growth to host plant signals, and infection. Despite this central role, hardly any information is available about their target structures and pathways. We are seeking to fill this gap applying genetic, biochemical, bioanalytical, and microscopy techniques combined with recent advancements from the redox-signaling field. more...
