Micrographic imaging of cell wall chitin distribution by Calcofluor
White staining. Wild-type (a) and myo1 (b) strain cultures were
treated with 2 mM BDM, 6.25 µM NZ, or treated simultaneously with 2 mM
BDM and 6.25 µM NZ (BDM+NZ) for 24 h and later stained with Calcofluor
White to visualize chitin deposition. Untreated control cultures of wild-type
(a), myo1 (b), chs3 (c), and
myo1chs3 (d) strains are shown. Upper panels represent a
collage of u.v. fluorescence micrographs and the lower panels represent the
corresponding light micrographs for each group. Arrowheads indicate putative
aborted bud structures. All images were captured at the same exposure time and
magnification (1000×). Bar=5 µm.
