Figure 5. Localization of satellite repeats on metaphase chromosomes of S. latifolia.

Figure 5

FISH experiments were performed simultaneously with two probes labeled by different fluorochromes (red or green, as indicated) in order to investigate the co-localization of sequence variants of the STAR repeats (A–B), 15Ssp and X43.1 (C) and TRAYC-like repeats (D–F). (A) Co-localization of the CL16/STAR-C repeat consensus (16HL2) and its sequence variant (16HL3). (B) The probes for a different region of the CL16/STAR-C consensus (16HL1) and for the chromosome Y-enriched subfamily CL398/STAR-Y (398H2). (C) Consensus probes for CL87/15Ssp (87H1) and X43.1 (12H5) satellites. Co-localization of the CL68/TRAYC-like consensus (68H1) with X43.1 (12H5) (D), CL156 (156H1) (E) and with the CL68 subfamily (68H2) (F). The inset in (F) is an example of the Y chromosome hybridized to 68H2 and 398H2, showing the localization of their interstitial signals on different chromosome arms. The chromosomes were counterstained with DAPI (blue). Sex chromosomes are indicated with X and Y. The positions of probes within repeat monomers are shown on Fig. 4 and their sequences are provided in Table 2.
