CC-2911 y-y

From Catherine Nicholson-Guthrie, Indiana University School of Medicine, June 1993, her #14
Phenotype: chlorophyll deficient, yellow under all growth conditions
The y-y strain, which is a UV-induced derivative of a y1 strain, fails to convert protochlorophyllide to chlorophyll either in the dark or in the light. These strains frequently acquire second-site suppressors and become green. CC-2911 is the best y-y in our collection currently. The American Type Culture Collection has these strains in frozen storage.
