A family of related sequences associated with (TTTAGGG)n repeats are located in the interstitial regions of wheat chromosomes.

A family of related sequences associated with (TTTAGGG)n repeats has been cloned from the wheat cultivar Chinese Spring. These sequences reveal a high level of polymorphism between wheat varieties when used as restriction fragment length polymorphism (RFLP) probes. Although this family of sequences contains motifs homologous to the repeats in the telomeres of wheat, they are located at interstitial sites on wheat chromosomes.
