- •
rDNAs (5S and 45S), telomeric repeats and C0t DNAs in Chrysanthemum boreale chromosome are localized.
- •
FISH karyotype of C. boreale is clarified.
- •
45S rDNA loci show colocalization with Arabidopsis -type telomeric repeats.
- •
Repetitive DNAs (C0t DNA) of C. boreale localize predominantly in pericentromeric and telomeric regions.
- •
Relative proportions of repetitive sequences in C. boreale genome is discussed.
