Hypersensitivity to cell wall inhibitors of
different S. pombe strains. Wild-type (HM123),
rho2Δ (KN-1), Pnmt81-pck1 (MA20),
Pnmt81-pck2 (MA21), Pnmt81-pck1 rho2Δ
(TMC110), and Pnmt81-pck2 rho2Δ (TMC111) cells were
grown at 28°C in EMM with thiamine, spotted on EMM with thiamine
plates at 4 × 106 and 106 cells/ml, and
incubated 2–3 d at 28°C. Drug concentrations were as follows:
Calcofluor (CF) (0.5 mg/ml), Papulacandin B (Pap) (2 and 4 μg/ml);
and Echinocandin (Ech) (1, 2, and 4 μg/ml).
