Summary The gene encoding subunit 5 of the NADH dehydrogenase complex (ND 5) has been identified in Oenothera mitochondria from a cDNA clone. The coding region is interrupted by a type II intron of 850 nucleotides and a second intervening sequence of 357 nucleotides. Genomic sequence rearrangement within the first intron creates a nontranscribed partial copy of the gene. The intact ND 5 gene is transcribed in a complex pattern with mRNAs including the 5 S rRNA sequence. Excision of the two introns appears to proceed slowly in vivo since the steady state mitochondrial RNA contains significant proportions of unprocessed precursor molecules.
