The ntf2–2ts MAD2Δ double mutant
is hypersensitive to microtubule-destabilizing drugs. (A)
ntf2–2ts is a unique benomyl-sensitive allele of
NTF2. NTF2, ntf2–2ts, ntf2–1ts, ntf2–2ts
MAD2Δ, and ntf2–1ts MAD2Δ cells were grown
at 25°C overnight, and 100,000, 10,000, 1000, 100, and 10 cells were
spotted onto YEPD (left) and 10 μg/ml benomyl plates (right). Plates
were incubated at 25°C for 4 days. (B) The ntf2–2ts
MAD2Δ double mutant is hypersensitive to nocodazole.
NTF2, MAD2Δ, ntf2–2ts,
and ntf2–2ts MAD2Δ were grown at 25°C overnight,
were diluted to 0.2 × 106 cells/ml into YEPD
containing 15 μg/ml nocodazole, and growth was monitored by
OD600.
