Senescence-specific mitochondrial DNA molecules in P. anserina: evidence for transcription and normal processing of the RNA

Abstract

In Podospora anserina the phenomenon of senescence was previously shown to be correlated with the presence of senescence-specific circular DNAs (senDNAs), resulting from the amplification of distinct regions (α, β, γ and ε) of the mitochondrial chromosome. The β region gives rise to senDNAs with variable sizes, but sharing a 1-kb common sequence. Here, we… (More)
