title: Distribution of mitochondrial r1-type introns and the associated open reading frame in the yeast genus Kluyveromyces.
abstract: We have sequenced the intron in the large subunit ribosomal RNA gene from the mitochondrion of Kluyveromyces lactis. It is a typical group I intron but, unlike the corresponding intron (r1) in Saccharomyces cerevisiae, it does not contain an open reading frame. This intron is widespread in the genus Kluyveromyces although intron-less strains were also found in some species of this genus. Sequences homologous to the open reading frame of the S. cerevisiae ribosomal intron were detected in some strains of K. waltii, K. thermotolerans and K. africanus.
