Telomeres in plants and humans: not so different, not so similar

P Procházková Schrumpfová, M Fojtová, J Fajkus - Cells, 2019 - mdpi.com
Parallel research on multiple model organisms shows that while some principles of telomere
biology are conserved among all eukaryotic kingdoms, we also find some deviations that …

Single-molecule targeted accessibility and methylation sequencing of centromeres, telomeres and rDNAs in Arabidopsis

W Mo, Y Shu, B Liu, Y Long, T Li, X Cao, X Deng… - Nature Plants, 2023 - nature.com

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

Elucidation of the DNA end-replication problem in Saccharomyces cerevisiae

J Soudet, P Jolivet, MT Teixeira - Molecular cell, 2014 - cell.com
The model for telomere shortening at each replication cycle is currently incomplete, and the
exact contribution of the telomeric 3′ overhang to the shortening rate remains unclear …

Germline replications and somatic mutation accumulation are independent of vegetative life span in Arabidopsis

JM Watson, A Platzer, A Kazda… - Proceedings of the …, 2016 - National Acad Sciences
In plants, gametogenesis occurs late in development, and somatic mutations can therefore
be transmitted to the next generation. Longer periods of growth are believed to result in an …

[HTML][HTML] C. elegans telomeres contain G-strand and C-strand overhangs that are bound by distinct proteins

M Raices, RE Verdun, SA Compton, CI Haggblom… - Cell, 2008 - cell.com
