Fig. 7. Thin section electron microscopy of meu14 cells. (C) EM images of the meu14 cells (i and iv), and enlarged views (ii, iii, v and vi) to show the abnormal localization of the SPBs in the meu14 cells. (D) An EM image of the meu14 cells shows that the forespore membrane abnormally encloses the spindle (i). An example (ii) demonstrates that the absence (iii) or presence (iv) of SPB affects the proper formation of the forespore membrane in the meu14 cells. Pictures of wild-type cells are encircled by black lines. White arrowheads (spindle), white arrows (SPB) and black arrows (forespore membrane). White scale bar, 1 µm. Black scale bar, 0.5 µm.
