Description:

Wild-type 2137 mt+ was recovered from a cross between 21gr mt+ and 137c mt-. Wild-type 21gr mt+ grew in clumps in minimal medium, was green in the dark, and was positively phototactic. Wild-type 137c mt- was yellow in the dark (y1) and negatively phototactic. Wild-type 2137 mt+ was chosen as having good-mating, non-clumping, green-in-the-dark, and negatively-phototactic phenotypes. The original 2137 mt+ strain has been cloned four times to retain its original phenotype. This is the strain used as wild type. It has been continuously maintained with acetate medium in darkness.
