Occurrence and transcription of genes for nad1, nad3, nad4L, and nad6, coding for NADH dehydrogenase subunits 1, 3, 4L, and 6, in liverwort mitochondria.
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.
