Chromosomal Locations of Gene-Like Fragment 12 by FISH.

Mitotic metaphase (A) and meiotic pachytene (B) cells of rye with Bs after single-copy FISH with labeled extended gene-like fragment 12 (in green). FISH with the B-specific E3900 repeat (in blue) allowed the identification of Bs. Note multiple signals (arrow heads) of fragment 12 along the Bs in pachytene chromosome. A-localized FISH signals are indicated by arrows. The inset shows further enlarged B. DAPI, 4′,6-diamidino-2-phenylindole. Bar = 10 µm.
