Monensin, a monovalent cation ionophore, was used to investigate some steps of the wall synthesis and morphogenesis in Candida albicans blastospores. In the presence of the drug, the pathogenic yeast developed enormous wall and septum thickenings that reacted intensely and specifically with wheat germ agglutinin and chitinase coupled to colloidal gold and fluorescein isothiocyanate. Therefore, the aberrant zones are interpreted as sites of chitin accumulation. The increased production of this homopolymer, also demonstrated by the chemical analysis of cell wall preparations, implies that monensin interferes in some way with the regulatory factors that normally control, in space and time, chitin synthetase activity.

Abstract

Monensin, a monovalent cation ionophore, was used to investigate some steps of the wall synthesis and morphogenesis in Candida albicans blastospores. In the presence of the drug, the pathogenic yeast developed enormous wall and septum thickenings that reacted intensely and specifically with wheat germ agglutinin and chitinase coupled to colloidal gold and fluorescein isothiocyanate. Therefore, the aberrant zones are interpreted as sites of chitin accumulation. The increased production of this homopolymer, also demonstrated by the chemical analysis of cell wall preparations, implies that monensin interferes in some way with the regulatory factors that normally control, in space and time, chitin synthetase activity.
