Genetics of Eukaryotic Microorganisms
Molecular Biology of Fungi 2022 - Call for Registration and Abstract submission
The bi-annual conference of the special group 'Fungal Biology and Biotechnology' of the VAAM and the Genetics Society (GfG) will be held this year again, for the first time after the outbreak of the COVID-19 pandemic. Fungal researchers from Germany, Europe and beyond will meet from 7th-9th of September in Kaiserslautern. Main Topics are:
- Plant Pathology
- Cell Biology
- Multicellular Development
- Pathogenesis of Infectious Disease
- Sensing and Signalling
The program of MBF 2022 is now available here.
Minisymposium of the VAAM special group 'Biology und Biotechnology of Fungi'
Associated to the annual conference of the VAAM, Daniela Nordzieke (University of Göttingen) and Arne Weiberg (LMU) invited the members of the VAAM special group 'Biology and Biotechnology of Fungi' for a joined conference on 'Communication in Fungi'. In a total of seven excellent presentations, diverse signaling molecules ranging from RNA, secondary metabolites, volatiles and carbohydrate storages were discussed. The Minisymposium started with the presentation of the invited speaker, Prof. Dr. Susanne Zeilinger-Migisch (University of Innsbruck), who presented recent data about the control agent Trichoerdema atroviride, a fungus able to communicate with plant hosts and plant pathogenic fungi. Also the presentation of Nora Kühne, a PhD student from the University of Göttingen, raised the attention of the audience. Her talk about an unusual maturation mechanism of fungal effectors was selected as the best presentation out of the selected abstract.

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 germling fusion, sexual development, chemotropic growth to host plant signals, and plant infection. Seeking for the identification of signals, receptors and downstream pathways, we apply genetic, biochemical, bioanalytical, and microscopy techniques. Based on these findings, we also evaluate communication factors for their probable use in biotechnological applications. more...
