abstract：:Schizosaccharomyces pombe Cdc23 is an essential DNA replication protein, conserved in eukaryotes and functionally homologous with Saccharomyces cerevisiae Dna43 (Mcm10). We sought evidence for interactions between Cdc23 and the MCM2-7 complex, a component of both the pre-replicative complex and the replication fork. C...

abstract：:In the filamentous ascomycete fungus Podospora anserina, senescence is associated with dramatic changes of the juvenile mitochondrial genome. During senescence specific regions of the non-senescent genome are excised, ligated and amplified as a plasmid. In this paper, we report our studies on nuclear-mitochondrial ext...
