strains, both expressing Mlc1-YFP, were grown under hyphal-inducing conditions. In both mutants, no spot of Mlc1-YFP is present, but a crescent remains. (C-E) DIC images of mutant hyphal cells (C,D) compared to wild-type hyphal cells (E). In both mutants, the hyphae are broader and more kinked than the wild-type hyphae. Bar, 10 µm.
