The genus Cestrum in the Solanaceae family is unusual in lacking Arabidopsis-type telomeres (TTTAGGG)n, although short interstitial telomeric sequences (ITSs) occur scattered throughout the genome in both orientations. To isolate candidate telomeric sequences in Cestrum we assumed that some of the ITSs were residues of the original telomeres and that they may still be located in the vicinity of present-day telomeres. Three sequence types associated with ITSs were cloned and characterized; these… CONTINUE READING
