Journal ArticleDOI
An ARGONAUTE4-containing nuclear processing center colocalized with Cajal bodies in Arabidopsis thaliana.
Carey Fei Li,Olga Pontes,Mahmoud El-Shami,Ian R. Henderson,Yana V. Bernatavichute,Simon W. L. Chan,Thierry Lagrange,Craig S. Pikaard,Steven E. Jacobsen +8 more
TL;DR: The results suggest a function for Cajal bodies as a center for the assembly of an AGO4/NRPD1b/siRNA complex, facilitating its function in RNA-directed gene silencing at target loci.
Journal ArticleDOI
Genome-wide association of histone H3 lysine nine methylation with CHG DNA methylation in Arabidopsis thaliana.
TL;DR: A high-resolution genome-wide map of H3K9m2 methylation is constructed by using chromatin immunoprecipitation coupled with whole genome Roche Nimblegen microarrays (ChIP-chip) and it is suggested that distinct mechanisms control H2K9M2 in different compartments of the genome.
Journal ArticleDOI
ATXR5 and ATXR6 are H3K27 monomethyltransferases required for chromatin structure and gene silencing.
Yannick Jacob,Suhua Feng,Chantal LeBlanc,Yana V. Bernatavichute,Hume Stroud,Shawn J. Cokus,Lianna M. Johnson,Matteo Pellegrini,Steven E. Jacobsen,Scott D. Michaels +9 more
TL;DR: ATXR5 and ATXR6 form a new class of H3K27 methyltransferases and that H 3K27me1 represents a previously uncharacterized pathway required for transcriptional repression in Arabidopsis.
Journal ArticleDOI
LHP1, the Arabidopsis homologue of HETEROCHROMATIN PROTEIN1, is required for epigenetic silencing of FLC
Joshua S. Mylne,Lynne Barrett,Federico Tessadori,Stéphane Mesnage,Lianna M. Johnson,Yana V. Bernatavichute,Steven E. Jacobsen,Paul Fransz,Caroline Dean +8 more
TL;DR: The localization of VRN1 was explored and found it to be associated generally with Arabidopsis chromosomes but not the heterochromatic chromocenters, suggesting thatVRN1 may contribute to chromatin silencing that is not meiotically stable.
Journal ArticleDOI
Two-Step Recruitment of RNA-Directed DNA Methylation to Tandem Repeats
TL;DR: It is shown that the FWA tandem repeats are necessary and sufficient for de novo DNA methylation and that repeated character rather than intrinsic sequence is likely important, suggesting that repeat acquisition may be a general mechanism for the evolution of gene silencing.
