CC-2926 iso1 mt-

$30.00

From Ursula Goodenough, Washington University, July 1993

Phenotype: does not mate

The iso1 mutation is expressed only in minus gametes, but is not linked to the mating type locus. Cells in a culture of iso1 mutants differentiate either into minus or pseudo-plus cells, which can agglutinate with each another but do not fuse to form zygotes. This is an ARG7 insertional mutant obtained in CC-1861 arg7 mt- (now replaced in the collection by CC-3681), and is formally known as isolr:pARG7.8.
