MOM1 mediates DNA-methylation-independent silencing of repetitive sequences in Arabidopsis.
The heterochromatic regions around centromeres of animal and plant chromosomes are composed of tandem repetitive sequences, interspersed with transposons and transposon derivatives. These sequences are largely transcriptionally silent and highly methylated, and are associated with specifically modified histones. Although embedded in heterochromatin, Arabidopsis 5S ribosomal RNA genes are among ...
متن کاملMechanism of siRNA production from repetitive DNA.
RNAi is a conserved genome defense mechanism in eukaryotes that protects against deleterious effects of transposons and viral invasion. Repetitive DNA loci are a major source for the production of eukaryotic small RNAs, but how these small RNAs are produced is not clear. Quelling in Neurospora is one of the first known RNAi-related phenomena and is triggered by the presence of multiple copies o...
متن کاملAn SGS3-like protein functions in RNA-directed DNA methylation and transcriptional gene silencing in Arabidopsis.
RNA-directed DNA methylation (RdDM) is an important epigenetic mechanism for silencing transgenes and endogenous repetitive sequences such as transposons. The RD29A promoter-driven LUCIFERASE transgene and its corresponding endogenous RD29A gene are hypermethylated and silenced in the Arabidopsis DNA demethylase mutant ros1. By screening for second-site suppressors of ros1, we identified the RD...
متن کاملRNA polymerase V-dependent small RNAs in Arabidopsis originate from small, intergenic loci including most SINE repeats
In plants, heterochromatin is maintained by a small RNA-based gene silencing mechanism known as RNA-directed DNA methylation (RdDM). RdDM requires the non-redundant functions of two plant-specific DNA-dependent RNA polymerases (RNAP), RNAP IV and RNAP V. RNAP IV plays a major role in siRNA biogenesis, while RNAP V may recruit DNA methylation machinery to target endogenous loci for silencing. Al...
متن کاملTissue homogeneity requires inhibition of unequal gene silencing during development
Multicellular organisms can generate and maintain homogenous populations of cells that make up individual tissues. However, cellular processes that can disrupt homogeneity and how organisms overcome such disruption are unknown. We found that ∼100-fold differences in expression from a repetitive DNA transgene can occur between intestinal cells in Caenorhabditis elegans These differences are caus...
