FIG. 6.

Filamentation of C. albicans wild-type and mutant strains. Colonies were grown on M199 (pH 8) plates for 3 days at 37°C. The wild-type C. albicans reference strain DAY185 (A) was compared to C. albicans strains with mutations rim101/rim101Δ (D) and dfg16Δ/dfg16Δ (B) and to a dfg16Δ/dfg16Δ strain that had been complemented through integration of HIS1-DFG16 plasmid pKJB026 at the HIS1 locus (C). Both mutant C. albicans strains were transformed with plasmids pRIM101-405 (E, H) and pRIM101 (F, I) integrated into the RIM101 locus and empty vector controls (D, G). All strains in this comparison were prototrophic. All images are shown at the same magnification.
