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).
摘要
已分离并鉴定出一种新的长寿的嗜热栖热放线菌突变体。如正反交所示，其长寿特性是母系遗传的。分子分析鉴定出一种与线粒体DNA（mtDNA）具有同源性的扩增DNA物种（命名为pAL2-1）。这种DNA物种的存在与mtDNA重排以及移动内含子（plDNA）的延迟扩增相关。
