abstract：:A rearrangement of the mitochondrial genome of a long lived mutant of Podospora anserina is presented. It consists in the insertion of 191 bp of the LrDNA gene (coding for the large ribosomal RNA) at the junction between exon1 and intron alpha of gene co1 (coding for subunit 1 of cytochrome oxidase). This insertion is...
