FIGURE 7.
A general microtubule defect in mtr17-1, mtr3-1, and mtr4-1 mutants. Mutants are hypersensitive to the MT destabilizing drug benomyl. In contrast, null mutants of RRP6, SKI2, SKI3, and SKI8 are insensitive to the drug. Cells were serially diluted 10-fold and dilutions plated onto control media or media containing 10 µg/ml benomyl.
