Group II introns are found in rRNA, tRNA, and mRNA of organelles (chloroplasts and mitochondria) in fungi, plants, and protists, and also in mRNA in bacteria. The first intron to be identified as distinct from group I was the ai5γ group IIB intron, which was isolated in 1986 from a pre-mRNA transcript of the oxi 3 mitochondrial gene of Saccharomyces cerevisiae.
