Abstract The mitochondrial nad6 gene of maize was identified and mapped 1 kb downstream from the atp6 gene. It encodes a 220 amino-acid polypeptide. Using Northern hybridization experiments and RT-PCR analysis, we showed that both nad6 and atp6 are co-transcribed in maize mitochondria. RNA editing of the mitochondrial nad6 transcript was studied by cDNA sequencing. Twelve edited sites were identified at the same positions as those already identified in the wheat mitochondria nad6 transcript. Alignments of nucleotide and amino-acid sequences of the mitochondrial nad6 genes of maize, wheat, and Brassica campestris, show that the wheat gene encodes a shorter polypeptide (229 amino acids) than was previously thought.
