title: Occurrence and transcription of genes for nad1, nad3, nad4L, and nad6, coding for NADH dehydrogenase subunits 1, 3, 4L, and 6, in liverwort mitochondria.
abstract: The genes encoding subunits 1, 3, 4L, and 6 of NADH dehydrogenase (nad1, nad3, nad4L, nad6) in the mitochondrial genome of a liverwort, Marchantia polymorpha, were characterized by comparing homologies of the amino-acid sequences of the subunits with those of other organisms. The nad3 and nad4L genes are split by single and double group II introns, respectively. The 5'-half portion of the nad6 gene was repeated at an identity of 89% to form a reading frame consisting of 100 amino-acid residues. The Northern hybridization analysis showed that all four genes are transcribed in the liverwort mitochondria.
