Fig. 4. Synthetic lethality between vps1
and alleles of sla1 with actin defects. (A) The viabilities of various mutants after their SLA1-containing plasmid pTHY918 was lost on a 5-FOA plate: strainsYMC467 (sla1
), YMC468 (sla1
mgm1
), YMC469 (sla1
dnm1
) and YMC470 (sla1
vps1
) grown on SC-Ura plate (left) at 24°C were replica-plated onto a 5-FOA plate (right) and incubated at 24°C for 2 days. (B) The schematic structures of Sla1p and its deletion constructs to be used in the following experiments. (C) The test of the strain YMC470 (sla1
vps1
) to lose the SLA1-containing plasmid pTHY918 in the presence of various sla1 deletion constructs: pRS314 (vector, lane 1), pYGS203 (sla1
3rdSH3, lane 2), pTHY1114 (sla1
all SH3, lane 3), pTHY1115 (sla1
SR, lane 4) and pTHY1089 (Sla1FL, lane 5).
