Expression of a mutant fimbrin (Sac6p) with an
altered actin-binding domain suppresses the invasion and cell
elongation defects of an act1–120/act1–120 diploid.
Strains BCY209 (ACT1/ACT1), BCY210
(act1–120/act1–120), BCY372
(sac6/sac6), BCY412 (act1–120/act1–120
〈SAC6+〉), BCY411 (act1–120/act1–120
〈sac6–10〉), BCY432
(act1–111/act1–111 〈sac6–10〉), and
BCY433 (act1–124/act1–124
〈sac6–10〉), where genotypes in angle brackets refer
to relevant genotypes of plasmids AAB117 (SAC6 URA3 CEN)
and AAB289 (sac6–10 URA3 CEN) (Brower et
al., 1995), were streaked to SLAD agar and incubated at 30°C
for 4 d. The resultant colonies were photographed before and after
washing the agar surface. Long cells were quantified as described in
MATERIALS AND METHODS and are reported with SE. Bar, 500 μm.
