CO initiation but not CO completion is required for the reciprocal localization of HTP-1/2 and SYP-1 in diakinesis.

<p>(A) SYP-1 staining of representative diplotene nuclei. Scale bars are 2 µm. (B) HTP-1/2 (red) and SYP-1 (green) staining of wild-type diakinesis chromosomes. (C) The same staining of <i>[mus-81; xpf-1]</i>, <i>[slx-1; xpf-1]</i>, <i>[mus-81; him-6]</i> and <i>[slx-1; him-6]</i> double mutants nuclei. Filled arrowheads indicate DNA bridges. Open arrowheads indicate the chromosomes shown in the close ups. Scale bars are shown in red.
