Telomeric-like sequence (TTTAGGG)_n sites in representative species of Carduoideae (A,B), Mutisioideae (C) and Gymnarhenoideae (D) tribes assessed by FISH analysis. Telomeric sites and interstitial telomeric repeat (ITR) sites are shown as red fluorescent signals and the chromosomes are counterstained with 4, 6-diamidino-2-phenylindole (DAPI) (blue colour). (A) Galactites tomentosa (2n = 20) showing 10 ITR sites. (B) Carlina hispanica (2n = 18 + 2B) with six ITR sites. (C) Nassauvia sprengelioides (2n = 44) with four ITR sites). (D) Gymnarrhena micrantha (2n = 20) showing ten ITR sites. Faint ITR signals are marked with arrowheads. Scale bars: 10 µm.
