Pinning down loose ends: mapping telomeres and factors affecting their length
A degenerately repeated sequence, proximal to the telomere heptanucleotide repeat in maize, contains restriction enzyme sites that permit the separation of telomeres from the rest of the chromosomes. Probing with a telomere-specific oligonucleotide revealed genotype-dependent telomere lengths that v...

| description | A degenerately repeated sequence, proximal to the telomere heptanucleotide repeat in maize, contains restriction enzyme sites that permit the separation of telomeres from the rest of the chromosomes. Probing with a telomere-specific oligonucleotide revealed genotype-dependent telomere lengths that vary more than 25-fold in maize among the 22 inbreds that have been surveyed. These lengths were found to segregate reproducibly in a recombinant inbred family where 50% of the variation can be accounted for by three loci. The dynamic control over telomere length in maize appears to act rapidly to achieve new genotypically determined telomere lengths in the F1. Clones of telomere proximal sequences were used to map restriction fragment length loci at the distal ends of eight of 20 chromosome arms |
