Unlinked Noncomplementation: Isolation of New Conditional-Lethal Mutations in Each of the Tubulin Genes of Saccharomyces cerevisiae .

Mutations in genes of Saccharomycescereuziiae that code for proteins that interact with P-tubulin were sought by screening for unlinked mutations that fail to complement mutations in the single P-tubulin-encoding gene (TUBZ). Among the first three noncomplementing mutations examined, two are linked ...
