Genetic interactions between SHE4 and actin-related genes and
MYO5. (A) Summary of genetic interactions. Each mutant strain was
crossed with she4Δ (YKT275 or YKT276), and resultant diploid
cells were sporulated and dissected for tetrad analysis. The growth
characteristics of the resulting double or triple mutants were determined at
25°C. The mutant strains used were YMW211U (arp2-1), YMW221U
(arp2-2), YKT130 (vrp1Δ), YKT218
(sla1Δ), DDY322 (abp1Δ), DDY1520
(aip1Δ), YKT382 (bni1Δ), YKT388
(cla4Δ), DDY1226 (cof1-22), DDY1024
(pfy1-116), DDY949 (rvs167Δ), DDY318
(sac6Δ), YKT186 (sla2Δ), YKT91
(myo3Δ myo5-1), YKT93 (myo3Δ
myo5-218), and YKT111 (myo3Δ myo5-360). (B)
Genetic interactions of arp2-1, arp2-2, sla1Δ, and
vrp1Δ with she4Δ mutation. Diploid cells
obtained from an indicated cross were sporulated, dissected, and grown at
25°C for 3–4 d before being photographed. Colonies were then replica
plated to determine the segregation of the marked mutant alleles. Tetrad
genotype (TT, tetratype; PD, parental ditype; and NPD; nonparental ditype) is
indicated, and the identity of the double mutant spore(s) is shown in
parentheses.
