Abstract Organellar DNA, i.e. a mixture of plastid and mitochondrial DNAs, was purified from the rhodophyte Chondrus crispus and analysed with restriction endonucleases. Mitochondrial DNA fragments were identified by heterologous hybridization, cloned, mapped and partially sequenced. The mitochondrial genome of C. crispus consists of a 25.9 kb circular molecule on which twenty genes were localized. Compared with other plant mitochondrial genomes, C. crispus mitochondrial DNA appears as a relatively small molecule with a high coding capacity and a specific gene organization. The use of a modified genetic code and the absence of RNA editing, previously reported for the cox3 gene, is a general characteristic of the sequenced genes of this molecule. This is the first detailed description of a red algal mitochondrial genome.
