Synthetic lethality of rho2Δ and
mok1–664 mutations. (A) Wild-type (HM123),
rho2Δ (KN-1), Pnmt81-pck2 (MA21),
mok1–664 (DH664), Pnmt81-pck2 rho2Δ
(TMC111), mok1–664 rho2Δ (TMC113), and
mok1–664 pck2Δ (SKP100) cells were grown in YES
medium at 28°C, spotted on YES solid-medium plates, and incubated for
3 d at different temperatures. (B) Phase-contrast micrographs of
the same strains grown in YES liquid medium for 20 h at 32°C.
