Using slot-blot and fluorescent in situ hybridization (FISH), we found no evidence for the presence of the Arabidopsis-type telomeric sequence (TTTAGGG)n at the chromosome termini in any of the Cestrum species we investigated. Probing for the human-type telomere (TTAGGG)n also revealed no signal.

This paper highlighted a salicylic acid-inducible Caulimoviral promoter fragment from Cestrum yellow leaf curling virus (CmYLCV). Interaction of Arabidopsis transcription factors TGA3 and WRKY53 on CmYLCV promoter resulted in the enhancement of the promoter activity via NPR1-dependent
Telomeres, nucleoprotein structures at the ends of linear eukaryotic chromosomes, are crucial for the maintenance of genome integrity. In most plants, telomeres consist of conserved tandem repeat units comprising the TTTAGGG motif. Recently, non-canonical telomeres were described in several plants
