Abstract:
Subcloning of a clone of the 120-bp family of rye, pSc119, has produced two extremely useful probes. pSc119.1 assays rye-specific dispersed repetitive sequence families. It is present on all seven rye chromosomes and hybridizes to the entire length of each chromosome, with the exception of some telomeres and the nucleolar organiser region. pSc119.2, in contrast, hybridizes predominantly to the telomeric regions of rye chromosomes, with some interstitial sites. Unlike pSc119.1, it assays similar repetitive sequence families in both wheat and rye chromosomes.
