[HTML][HTML] Telomere length deregulation and enhanced sensitivity to genotoxic stress in Arabidopsis mutants deficient in Ku70
The Ku70/80 heterodimer is a critical component of the non‐homologous end‐joining (NHEJ)
pathway and of the telomere cap in yeast and mammals. We report the molecular …

Living with genome instability: plant responses to telomere dysfunction
Loss of telomere function in metazoans results in catastrophic damage to the genome, cell
cycle arrest, and apoptosis. Here we show that the mustard weed Arabidopsis thaliana can …

Disruption of the telomerase catalytic subunit gene from Arabidopsis inactivates telomerase and leads to a slow loss of telomeric DNA
Telomerase is an essential enzyme that maintains telomeres on eukaryotic chromosomes.
In mammals, telomerase is required for the lifelong proliferative capacity of normal …

Molecular analysis of telomere fusions in Arabidopsis: multiple pathways for chromosome end‐joining
End‐to‐end fusion of critically shortened telomeres in higher eucaryotes is presumed to be
mediated by nonhomologous end‐joining (NHEJ). Here we describe two PCR‐based …
