Genetics of Eukaryotic Microorganisms
Posterprize 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!
13th Symposium of the VAAM Special Group Biology and Biotechnology of Fungi
We are happy to invite you to Göttingen to the biannual conference on Molecular Biology of Fungi “MBF2019”. The conference will start at noon on Thursday, September 19th and will end on Saturday 21st, 2019. The MBF2019 will be the 13th event in a successful series and addresses all members of the VAAM special group “Biology and Biotechnology of Fungi” as well as all researches working in the field of fungal biology. For the first time the meeting will be jointly organized by the GenAG “Fungal Genetics” of the German Society of Genetics (GfG).
The meeting brings together researchers working on diverse aspects of fungal biology and genetics. Main topics of the meetings will include plant pathology, cell biology, and multicellular development, pathogenesis of infectious diseases, as well as sensing and signaling.
Abstract submission open!
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...
