The centromeric regions of potato chromosomes contain megabase-sized tandem arrays of telomere-similar sequence.

Ahmet L Tek1, Jiming Jiang.   

Abstract

Telomere-similar sequences have been found in non-telomeric regions in various eukaryotic species. Centromeric regions often harbor such interstitial telomeric repeats (ITRs). We isolated a 2.8 kb ITR, pSbTC1, in a diploid potato species Solanum bulbocastanum. DNA sequences related to the pSbTC1 family are widely distributed in different Solanum species. The pSbTC1-related sequences are organized into tandem arrays and located mainly in the centromeric regions of potato chromosomes. Most notably, the pSbTC1-related sequences have undergone extensive amplification and a single array can span up to multiple megabases. These results suggest that the pSbTC1-related sequences are not simple relics of ancient events in karyotype evolution, such as chromosomal fusions. We also demonstrated that the pSbTC1-related sequences are heavily methylated and are associated with highly condensed centromeric heterochromatin.
