Finally, we have found that expression of human gamma-tubulin or overexpression of S. pombe gamma-tubulin causes no significant alteration of resistance to the antimicrotubule agents benomyl, thiabendazole and nocodazole.

The cold sensitivity of two alleles is strongly suppressed by the antimicrotubule agents benomyl and nocodazole and a third allele is essentially dependent on these compounds for growth.

In experiments in which microtubules were depolymerized with benomyl, mipAD159 nuclei exited mitosis significantly more quickly (as judged by chromosomal condensation) than nuclei in a control strain.

Growth defects of tub4 mutants lacking either or both carboxy-terminal domains are suppressed by the microtubule destabilizing drug benomyl. tub4 carboxy-terminal mutants arrest as large budded cells with short bipolar spindles positioned at the bud neck.

The disruption of any of these genes results in similar phenotypes: the gim null mutants are synthetically lethal with tub4-1 and super-sensitive towards the microtubule-depolymerizing drug benomyl.

In the presence of a low amount of benomyl, a microtubule-depolymerizing agent, however, a dynein mutant diploid strain exhibits a more pronounced chromosome loss phenotype than the control, indicating that cytoplasmic dynein plays a role in chromosome segregation.

In budding cells, most MTs are nucleated by three to six small and motile gamma-tubulin-containing MTOCs at the boundary of mother and daughter cell, which results in a polarized MT array.
Disruption of MTs with benomyl and subsequent washout led to an equal distribution of the MTOC and random formation of highly motile and randomly oriented MTs throughout the cytoplasm.
