Electron microscopic observation of the
arf1-18 ts mutant.
arf1-18 ts mutant cells were grown to an
early log phase at 23°C, further incubated at 23°C (A) or at 37°C
for 1 h (B, C, and D) and 2 h (E and F), and then subjected
to electron microscopy. In A, B, and E, large arrows mark Golgi
structures. In D and F, various kind of vesicles are indicated by
arrowheads, a double arrowhead, and small arrows. Bars: A, C, and E,
1.0 μm; B, D, and F, 500 nm.
