rho2+ overexpression does not cause
any effects in the absence of Pck2p. (A) Growth of wild-type (HM123),
pck1Δ (TP134–3B), and pck2Δ
(TP169–1C) cells transformed with pREP3X, pREP4X,
pREP3X-rho2, or pREP4X-rho2. Cells were
grown on EMM plates without thiamine. (B) Localization of F-actin in
(a) HM123, (b) TP169–1C, (c) HM123 transformed with
pREP3X-rho2, (d) TP169–1C transformed with
pREP3X-rho2. Bar, 5 μm.
