The control of cell shape is altered in phg2, myoVII, and talin mutant cells. Wild-type and mutant cells were incubated for 1 h in either HL5 medium or PB, and then fixed and processed for scanning electron microscopy. The cell shape of phg2, myoVII, and talin mutant cells in PB was altered compared with wild-type or phg1 cells. Bar, 5 μm.
