Hyphal morphogenesis of Candida albicans is important for its pathogenesis. Here, we showed that the filamentous growth of C. albicans requires vacuolar H+-ATPase function. Results showed that levels of Vma4 and Vma10 increased in cells undergoing hyphal growth compared to those undergoing yeast growth. Deleting VMA4 or VMA10 abolished vacuolar functions and hyphal morphogenesis. These deletion mutants were also characterized as avirulent in a mouse model of systemic infection. Furthermore, VMA4 and VMA10 deletion strains showed hypersensitivity to fluconazole, terbinafine, and amphotericin B. Based on these findings, Vma4 and Vma10 are not only involved in vacuole biogenesis and hyphal formation, but also are good targets for antifungal drug development in C. albicans.
