[HTML][HTML] Telomere length deregulation and enhanced sensitivity to genotoxic stress in Arabidopsis mutants deficient in Ku70

K Riha, JM Watson, J Parkey, DE Shippen - The EMBO journal, 2002 - embopress.org
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

K Riha, TD McKnight, LR Griffing, DE Shippen - Science, 2001 - science.org
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 …

Mre11 deficiency in Arabidopsis is associated with chromosomal instability in somatic cells and Spo11-dependent genome fragmentation during meiosis

…, J Siroky, P Mokros, D Schweizer, K Riha - The Plant …, 2004 - academic.oup.com
The Mre11/Rad50/Nbs1 complex is involved in many aspects of chromosome metabolism.
Aberrant function of the complex is associated with defects in the DNA checkpoint, double-…

Disruption of the telomerase catalytic subunit gene from Arabidopsis inactivates telomerase and leads to a slow loss of telomeric DNA

MS Fitzgerald, K Riha, F Gao, S Ren… - Proceedings of the …, 1999 - National Acad Sciences
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

M Heacock, E Spangler, K Riha, J Puizina… - The EMBO …, 2004 - embopress.org
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 …

[HTML][HTML] siRNA–Mediated Methylation of Arabidopsis Telomeres

…, L Daxinger, B Vyskot, W Aufsatz, K Riha - PLoS …, 2010 - journals.plos.org
Chromosome termini form a specialized type of heterochromatin that is important for
chromosome stability. The recent discovery of telomeric RNA transcripts in yeast and vertebrates …

Developmental control of telomere lengths and telomerase activity in plants

K Riha, J Fajkus, J Siroky, B Vyskot - The Plant Cell, 1998 - academic.oup.com
Telomere lengths and telomerase activity were studied during the development of a model
dioecious plant, Melandrium album (syn Silene latifolia). Telomeric DNA consisted of …

[PDF][PDF] Nonsense-mediated mRNA decay modulates immune receptor levels to regulate plant antibacterial defense

…, C Jonak, JM Jiménez-Gómez, JE Parker, K Riha - Cell host & …, 2014 - cell.com
Nonsense-mediated mRNA decay (NMD) is a conserved eukaryotic RNA surveillance
mechanism that degrades aberrant mRNAs. NMD impairment in Arabidopsis is linked to …

[PDF][PDF] Ku suppresses formation of telomeric circles and alternative telomere lengthening in Arabidopsis

B Zellinger, S Akimcheva, J Puizina, M Schirato, K Riha - Molecular cell, 2007 - cell.com
Telomeres in mammals and plants are protected by the terminal t loop structure, the formation
of which parallels the first steps of intrachromatid homologous recombination (HR). Under …

Aberrant growth and lethality of Arabidopsis deficient in nonsense-mediated RNA decay factors is caused by autoimmune-like response

…, J Gloggnitzer, B Dekrout, C Jonak, K Riha - Nucleic acids …, 2012 - academic.oup.com
Nonsense-mediated RNA decay (NMD) is an evolutionarily conserved RNA quality control
mechanism that eliminates transcripts containing nonsense mutations. NMD has also been …
