Genetic functions of isolated maize mitochondria under model changes of redox conditions.

The template functions of maize mitochondrial genome have been studied under model conditions of redox potential created by the addition of potassium ferricyanide as an oxidising agent and sodium dithionite as a reducing agent. The addition of both potassium ferricyanide and sodium dithionite to the isolated mitochondria causes the changes in the activity of the mitochondria RNA and DNA synthesis. The data obtained indicate the possibility of redox regulation of genetic functions in isolated mitochondria.
