Journal ArticleDOI
Organization of telomeric and subtelomeric chromatin in the higher plant Nicotiana tabacum.
TL;DR: The results presented show apparent similarities in the organization of telomeric chromatin in higher plants and mammals.
Journal ArticleDOI
Telomeres in evolution and evolution of telomeres
TL;DR: It is described how telomere dysfunction, resulting in end-to-end chromosome fusions, can have a profound effect on chromosome evolution and perhaps even speciation.
Journal ArticleDOI
Subnuclear partitioning of rRNA genes between the nucleolus and nucleoplasm reflects alternative epiallelic states

TL;DR: Using fluorescence-activated sorting techniques, it is shown that active rRNA genes in Arabidopsis thaliana are present within sorted nucleoli, whereas silenced r RNA genes are excluded, and Bisulfite sequencing data reveal that rRN genes occupy distinct but changeable nuclear territories according to their epigenetic state.
Journal ArticleDOI
Telomere variability in the monocotyledonous plant order Asparagales.

TL;DR: In this paper, a group of monocotyledonous plants within the order Asparagales, forming a distinct clade in phylogenetic analyses, was reported previously to lack the typical Arabidopsis-type telomere (TTTAGGG) n.
Journal ArticleDOI
Identification of Nucleolus-Associated Chromatin Domains Reveals a Role for the Nucleolus in 3D Organization of the A. thaliana Genome.

TL;DR: Roles for NUC1 and the nucleolus in the spatial organization of chromosomes as well as telomere maintenance are revealed in wild-type plants and null mutants.
