title: Mitochondrial DNA rearrangements are correlated with a delayed amplification of the mobile intron (plDNA) in a long-lived mutant of Podospora anserina.
abstract: A new long-lived mutant of Podospora anserina has been isolated and characterized. Its longevity is maternally inherited as revealed by reciprocal crosses. A molecular analysis resulted in the identification of an amplified DNA species (designated pAL2-1) with homology to mitochondrial DNA (mtDNA). The presence of this DNA species is correlated with mtDNA rearrangements and a delayed amplification of the mobile intron (plDNA).
