Two color FISH mapping of CRWs (red) and GAAn (green) repeats on mitotic metaphase chromosome of CS containing 28 (24 telosomes from B-genome telosomes and 4 telosomes from t4AS and t4AL).

<p>The signals for CRWs were not detected on two pairs of t1BS and t6BS (arrowheads) (a). Instead GAAn repeats were presented in their centromeric region. Arrows indicate the t4AS (a). Arrows and arrowheads indicate the t1BS and t6BS, respectively (b).
