Phenotype: requires arginine; wall deficient

This strain is suitable as a recipient for transformation with the ARG7 gene, but isn’t as frequently requested as CC-1618 and some other strains.

Phenotype: requires arginine; wall deficient

This strain is transformable with the ARG7 gene. It did not appear to form diploids with a cw15 arg2 stock (CC-425 mt+) in crosses in 1983, suggesting that it may actually contain the arg7-8 (arg2) allele rather than the original arg7 as suggested by Howell’s designation. The arginine requirement has been stable.

From Stephen Howell, UC San Diego, June 1983

Designated by Howell as act-s, apparently indicating sensitivity to cycloheximide (Actidione). This is presumably the wild type allele, in contrast to the act1 or act2 mutations.

From Stephen Howell, UC San Diego, June 1983

Designated by Howell as mms-s, apparently indicating sensitivity to methionine sulfoximine. This is presumably the wild type allele, in contrast to the msr1 mutation.

Phenotype: temperature sensitive, cannot grow at 33 degrees

This is a mutant with a temperature-conditional cell cycle block, isolated in the 137c background. The block is very early in the cell cycle.

Phenotype: temperature sensitive, cannot grow at 33 degrees

This is a mutant with a temperature-conditional cell cycle block, isolated in the 137c background. The block is relatively late in the cell cycle.

Phenotype: temperature sensitive, cannot grow at 33 degrees

This is a mutant with a temperature-conditional cell cycle block, isolated in the 137c background. This mutant can complete more than one cell cycle at the restrictive temperature, but eventually blocks relatively late in the cycle.

Phenotype: temperature sensitive, cannot grow at 33 degrees

This is a mutant with a temperature-conditional cell cycle block, isolated in the 137c background. This mutant is blocked midway through the cell cycle.
