List of Mitochondrial Group II introns by Organism
Clicking on the intron name in the "Species" column brings up full information for individual introns, including intron sequence, GenBank annotation, flanking sequence, ORF sequence and intron RNA structure.
This is not meant to be a complete list of known mitochondrial introns and only ORF-containing introns are shown.
Researchers are referred to GOBASE for further information on organellar introns.
