Fig. 3. The telomere bouquet in Schizosaccharomyces pombe: the horsetail stage. Heterochromatic centromeres and telomeres are visualized with swi6-GFP (bright dots), which also lightly stains the entire nucleus. Here, the nucleus is elongated, as it is whipped about the cell in a swishing horsetail-like movement. To see this movement, please view our supplemental movies (http://jcs.biologists.org/supplemental/). Telomeres are clustered at one point in the nucleus, on the left, which is adjacent to the spindle pole body (SPB) attached to cytoplasmic microtubules (not visible here). Two centromeric dots can be seen in the interior of the nucleus. The third centromere is out of the plane of focus. Image courtesy of Ye Jin, UC Berkeley.
