Telomere protein and telomere protein homolog in Euplotes crassus [PDF]
, 1993 Telomeres, the nucleoprotein complexes at the end of the chromosomes, consist of repeated DNA sequence and the associated proteins. While the telomeric DNA has been well characterized in many species, the studies of the telomere-associated proteins lag ...

Journal of Integrative Plant Biology, EarlyView.A high‐quality reference genome for the elite peanut cultivar Zhonghua No. 5 revealed differing evolutionary paths between the two peanut subgenomes. SubA has higher overall gene expression and more open chromatin, whereas SubB has stronger structural organization, higher DNA methylation, and greater adaptive diversity associated with peanut evolution ...

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis
Journal of Integrative Plant Biology, EarlyView.The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

The Role of Telomere in Cell; Telomere Dysfunction and Tumorigenesis
مجله دانشکده پزشکی اصفهان, 2013 Telomeres consist of repetitive DNA sequences and a variety of non-nucleosomal proteins which are essential to survive chromosome. Telomeres protect the ends of chromosomes, but can also inhibit the expression of nearby genes, called telomere position ...

Subtelomeric repetitive elements determine TERRA regulation by Rap1/Rif and Rap1/Sir complexes in yeast [PDF]
Telomeric repeat-containing RNA (TERRA) has been implicated in the control of heterochromatin and telomerase. We demonstrate that yeast TERRA is regulated by telomere-binding proteins in a chromosome-end-specific manner that is dependent on subtelomeric ...

Orchid genome evolution and trait innovation
Journal of Integrative Plant Biology, EarlyView.Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

Restriction of Ku translocation protects telomere ends
Nature CommunicationsSafeguarding chromosome ends against fusions via nonhomologous end joining (NHEJ) is essential for genome integrity. Paradoxically, the conserved NHEJ core factor Ku binds telomere ends.

Telomere Structure in \u3ci\u3eEuplotes crassus\u3c/i\u3e: Characterization of DNA-Protein Interactions and Isolation of a Telomere-Binding Protein [PDF]
, 1990 The nucleoprotein structure of telomeres from Euplotes crassus was studied by using nuclease and chemical footprinting. The macronuclear telomeres were found to exist as DNA-protein complexes that are resistant to micrococcal nuclease digestion.
