An inositolless mutant strain of neurospora and its use in bioassays

Beadle, G. W.

Abstract

A mutant of Neurospora crassa requiring inositol for growth is described. Its use in a bioassay method for inositol has been investigated. The suggested method appears to be satisfactory in reproducibility and precision. It is useful for concentrations between 5 and 30 γ of inositol per 20 ml. of medium. Inositol contents of a number of materials are reported, but it has not been established that these values represent both free and combined forms of inositol.

The work reported here was supported by grants from the Rockefeller Foundation, the Research Corporation, and the Nutrition Foundation, Inc. Mutant Strain 37401 was detected and determined as in.ositolless by Miss Janet M. Wallace. The cross between Strains 37102 and 37401 was made and analyzed by Miss Agnes J. Vincenti. The author is indebted to Dr. D. W. Woolley for a sample of lipositol and to members of the Genetics Laboratories at St.anford University for helpful suggestions.
