Mitochondrial Biogenesis in Neurospora Crassa
The isolation of a new class of mutants permitting facultative anaerobiosis in Neurospora crassa is described. Backcross analyses to the obligate aerobe prototroph (An(-)) indicate single nuclear gene inheritance (An(-)/An(+)). An(+) and An(-) are indistinguishable in morphology and growth rates under aerobic conditions. Anaerobic growth requires nutritional supplements that are dispensable for...
متن کاملIdentification of two products of mitochondrial protein synthesis associated with mitochondrial adenosine triphosphatase from Neurospora crassa.
Soluble mitochondrial ATPase (F1) isolated from Neurospora crassa is resolved by dodecylsulfate-gel electrophoresis into five polypeptide bands with apparent molecular weights of 59000, 55000, 36000, 15000 and 12000. At least nine further polypeptides remain associated with ATPase after disintegration of mitochondria with Triton X-100 as shown by the analysis of an immunoprecipitate obtained wi...
متن کاملSpin-labeled mitochondrial lipids in Neurospora crassa.
The current interest in membrane models and membranes has increased the search for new probing techniques. Recently, spin labeling has been explored as a technique for investigating micelles.1 2 Although micelles are a rather primitive type of membrane model, the system is simple and forms a logical starting point for more ambitious studies. The main result of the micelle work was the demonstra...
متن کاملSynchronous Mitochondrial Division in Neurospora Crassa Emerson
Samples of mycelium of Neurospora crassa of known age were harvested from agar plates and examined with the electron microscope. The relative volume of the mitochondria was determined for mycelium of different ages. The volume measurements indicated that the mitochondria were dividing synchronously in fronts 6, 13, and 22k• hr behind the growing hyphal tips. The sequence of mitochondrial divisi...
