CC-1146 imp9 (sag1) mt+

$30.00

From Ursula Goodenough, Washington University, May 1981

Phenotype: does not mate

This mutant was induced by Goodenough et al. in a mt+ strain. It does not mate, and fails to agglutinate with cells of either mating type. It was subsequently shown to be a mutation at the SAG1 locus. This locus is not linked to mating type, but its mutants are sex-limited, expressed only in mt+ cells.
