$30.00

From Robert J. Spreitzer, University of Nebraska, August 2014

This wild-type strain was received by Laurens Mets from Ruth Sager in the 1970s, and was used as the mt+ parent for production of wild-type strain 2137 mt+ (CC-3269) (Spreitzer and Mets 1981). The 21gr mt+ strain (CC-1690) was originally selected for good growth in the dark from Smith’s 137 mt+ strain (Sager 1955). See also Smith and Regnery (1950). This strain has been maintained with acetate medium in darkness since 1980.
