Extranuclear mutant of Schizophyllum commune. 1978

J Nesvera

A mutant of the hymenomycete Schizophyllum commune was isolated which, owing to an extranuclear mutation, did not utilize acetate as the sole carbon source for growth. The growth of the mutant on glucose minimal medium was completely inhibited by sodium azide but was resistant to the effect of 2,4-dinitrophenol or oligomycin. Its endogenous respiration was cyanide-sensitive and was stimulated by 2,4-dinitrophenol to a considerably smaller degree than that of the wild-type strain. The experimental results obtained with this mutant suggest a defect in aerobic phosphorylation.

UI	MeSH Term	Description	Entries
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D009840	Oligomycins	A closely related group of toxic substances elaborated by various strains of Streptomyces. They are 26-membered macrolides with lactone moieties and double bonds and inhibit various ATPases, causing uncoupling of phosphorylation from mitochondrial respiration. Used as tools in cytochemistry. Some specific oligomycins are RUTAMYCIN, peliomycin, and botrycidin (formerly venturicidin X).	Oligomycin
D010101	Oxygen Consumption	The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body.

D005111	Extrachromosomal Inheritance	Vertical transmission of hereditary characters by DNA from cytoplasmic organelles such as MITOCHONDRIA; CHLOROPLASTS; and PLASTIDS, or from PLASMIDS or viral episomal DNA.
