Conidial Morphology of the Wild Type and the hdc1 Mutant T702.1.
(A) Ungerminated conidia of the wild type.
(B) Ungerminated conidia of mutant T702.1.
(C) Conidia of the wild type after germination on glass slides for 6 hr.
(D) Conidia of the mutant T702.1 after germination on glass slides for 6 hr.
Strains T702.2, T702.3, T702.4, and T702.5 (all hdc1/Tox2+) and five Tox2− hdc1 mutant strains (T717.1 through T717.5) showed a conidial morphology similar to that of T702.1 (data not shown). Bar in (A) and (B) = 12.5 μm; bar in (C) and (D) = 50 μm.
