摘要：

The expression of complex I and two homologues of bacterial and yeast NADH dehydrogenases, NDA and NDB, have been studied in potato leaf mitochondria. The mRNA level of NDA is completely light dependent and shows a diurnal rhythm with a sharp maximum just after dawn. NDA protein quantity and internal rotenone-insensitive NADH dehydrogenase activity are also light dependent. These findings suggest that NDA has a role in photorespiration and might be identical to the previously unidentified internal rotenone-insensitive NADH dehydrogenase.
