Rapamycin mimics the incompatibility reaction in the fungus Podospora anserina.
In filamentous fungi, a programmed cell death (PCD) reaction occurs when cells of unlike genotype fuse. This reaction is caused by genetic differences at specific loci termed het loci (for heterokaryon incompatibility). Although several het genes have been characterized, the mechanism of this cell death reaction and its relation to PCD in higher eukaryotes remains largely unknown. In Podospora ...
متن کاملThe Transcriptional Response to Nonself in the Fungus Podospora anserina
In fungi, heterokaryon incompatibility is a nonself recognition process occurring when filaments of different isolates of the same species fuse. Compatibility is controlled by so-called het loci and fusion of strains of unlike het genotype triggers a complex incompatibility reaction that leads to the death of the fusion cell. Herein, we analyze the transcriptional changes during the incompatibi...
متن کاملStress-dependent opposing roles for mitophagy in aging of the ascomycete Podospora anserina
Mitochondrial dysfunction is causatively linked to organismal aging and the development of degenerative diseases. Here we describe stress-dependent opposing roles of mitophagy, the selective autophagic degradation of mitochondria, in aging and life-span control. We report that the ablation of the mitochondrial superoxide dismutase which is involved in reactive oxygen species (ROS) balancing, do...
متن کاملThe Phenoloxidases * of the Ascomycete Podospora
N communication I11 (ESSEH 1966) of this series of papers, eleven loci belongI ing to six different linkage groups are described. These loci not only influence morphological characteristics, but also the formation of melanin pigments in Podospora. A preliminary biochemical analysis of these mutants has shown that at least two of these loci, the unlinked genes zonata and flexuosa, control the sy...
متن کاملSpore-killing meiotic drive factors in a natural population of the fungus Podospora anserina.
In fungi, meiotic drive is observed as spore killing. In the secondarily homothallic ascomycete Podospora anserina it is characterized by the abortion of two of the four spores in the ascus. We have identified seven different types of meiotic drive elements (Spore killers). Among 99 isolates from nature, six of these meiotic drive elements occurred in a local population. Spore killers comprise ...
