Fig. 5. Meiotic time-course experiment in the rec11 mutant. The cohesion-defect phenotype of linear elements and the temporal comparison of cytological events were analyzed in a time-course of strain ED4. (A) Arrowheads point to very small linear elements in a class A nucleus of the rec11 mutant. Arrow shows the spindle pole body; `n' is the nucleolus. (B) Class B morphology seen in the rec11 mutant (nucleus on left-hand side) and in the rec8rec11 double deletion strain ED2 (right-hand side). Arrowheads point at aberrant linear elements. (C) Class C morphology seen in the rec11 mutant (nucleus on the left-hand side) and in the rec8rec11 double deletion strain ED2 (right-hand side). Arrowhead shows a linear element. Bar, 1 µm. (D) Quantitation of the different classes. (E) Meiotic time-course as followed by DAPI staining.
