Boric Acid Disturbs Cell Wall Synthesis in Saccharomyces cerevisiae

Figure 2

Analysis of chitin and glucan distribution in BA-treated cells: fluorescence of calcofluor white (top) and aniline blue (bottom) stained cells. At BA concentrations of 0.4%, chitin-rich—and to a lesser extent, glucan-rich—material accumulates at the bud neck. The thickening of septa is evident particularly between cells in a chain.
