Although telomere sequences are considered to be highly conserved, there are switch-points in plant telomere evolution that are congruent with species' phylogenies. When Asparagales diverged, the Arabidopsis-type telomeric minisatellite repeat (TTTAGGG)(n) was first replaced by a human-type (TTAGGG)(n) repeat, and both were lost in Allium cepa (Alliaceae). We aimed to discover (1) when this loss occurred during divergence of Alliaceae and, (2) if (TTAGGG)(n) repeats were replaced by other known… CONTINUE READING
