Structure of a Gene for Subunit 9 of NADH Dehydrogenase (nad9) in Rice Mitochondria and RNA Editing of Its Transcript

We identified a gene for subunit 9 of NADH dehydrogenase (nad9) in rice mitochondrial DNA. Southern and Northern hybridizations demonstrated that rice nad9 is present in a unique region in mtDNA and is transcribed at a high level. The transcript of rice nad9 is edited at twelve positions.
