CC-735 y1 mt-

$30.00

From Itzhak Ohad, Hebrew University of Jerusalem, July 1979

Phenotype: yellow in the dark

This is Sager’s original y1 strain, as used by Ohad and others in their extensive series of experiments on Chlamydomonas greening. As y1 strains go, it seems to be reasonably stable, but users are advised to subclone for a good yellow-in-the-dark phenotype before using, since we maintain the strain in continuous light without selection for the yellow character. This strain can grow on nitrate.

CC-3992 is an equivalent strain, obtained by Hoober from Ohad. CC-1168 is a more stable allele at the same locus, and CC-1179 and CC-1180 contain a stable but temperature-conditional allele.
