Fig. 3. Rhizoid cells of wild type and Pphb7 disruptant. (A) A wild-type
rhizoid composed of 4 cells, viewed with Nomarski optics. The single asterisk
indicates a rhizoid apical cell and the double asterisk indicates a rhizoid
subapical cell. (B-G) A rhizoid composed of 8 cells in wild type (B-D) and
Pphb7dis-3 (E-G). The apical cell (B,E), third cell (C,F), and fifth cell
(D,G) viewed with Nomarski optics (right), and imaged under UV excitation
(left). The arrowheads indicate septa between the cells. Scale bar: in A, 100
µm for A; in B, 50 µm for B-G.
