Fig. 2. Rye heterochromatin as an indicator of telomere distribution. Single
z-sections of early meiotic prophase nuclei are shown. Telomeres (green) were
detected by FISH. Chromatin (red) was stained with DAPI. Heterochromatin is
visible as intensely staining DAPI regions (indicated with *). (A)
Dispersed telomeres prior to the bouquet. Five of the eight FISH signals in
this section are associated with heterochromatin. (B) Clustered telomeres
during the bouquet. A single heterochromatic region is evident. Bar, 10
µm.
