FIG. 1.
Core switching system in C. glabrata. Cells switch spontaneously among Wh, LB, DB, and vDB phenotypes discriminated on agar containing 1 mM CuSO4. In each box, low-magnification pictures of the dominant phenotypes are presented with examples of switches (a and b in parentheses). The frequencies of variant colony phenotypes are noted on the arrows pointing to those variant phenotypes.
