Disruption phenotypei
Reduced mitochondrial replication, transcriptional hypoxia response, sterility, arrest of germline cell proliferation, reduced frequency of apoptosis in the germline. Severe mitochondrial DNA depletion in somatic cells but does not result in major anomalies in worms development. Hypersensitive to ethidium bromide.2 Publications
