FIG. 3.

Hypha formation of C. albicans strains. Shown are sections of colonies grown for 3 days on Spider medium at 37°C. (A) Phenotypes of pmt single mutants. The indicated pmt6/pmt6 strains were complemented with a plasmid carrying PMT6 (pCT34) or PMT1 (pCT30); as controls a pmt1/pmt1 strain complemented by PMT6 (pCT35) and a wild-type strain (SC5314) were analyzed. (B) Phenotypes of pmt double mutants. The indicated pmt1/pmt1 pmt6/pmt6 double mutants were transformed with plasmid pCT30 (PMT1) or pCT35 (PMT6). (C) Suppression of the pmt6 phenotype by genes encoding signaling components. Strain CAP2-2391 (pmt6/pmt6) was transformed with plasmids carrying EFG1, CEK1, CPH1, or TPK2 genes (Table 1). As a control, an efg1/efg1 mutant strain transformed with pCT35 (PMT6) was analyzed.
