The ypt31-Δ/ ypt32-A141D, sec1-1 triple mutant accumulates Golgi structures. Electron microscopy of (A) ypt31-Δ/ypt32A141D (NSY348) mutant, (B) the ypt31-Δ/ypt32A141D, sec1-1 triple mutant transformed with YPT31 on a single copy vector (phenotypically sec1-1), and (C) the ypt31-Δ/ypt32-A141D, sec1-1 (NSY368) triple mutant. Arrows point to structures characteristic of each strain; arrowheads indicate ER that can be seen in continuity with the nuclear envelope in the triple mutant, but are also present in ypt31-Δ/ ypt32-A141D mutant cells. n, nucleus. Bar, 1 μm.
