Heterochromatin is a key architectural feature of eukaryotic chromosomes, which endows
particular genomic domains with specific functional properties. The capacity of …

Diverse classes of RNA, ranging from small to long non-coding RNAs, have emerged as key
regulators of gene expression, genome stability and defence against foreign genetic …

INTRODUCTION Changes in histone posttranslational modifications are associated with
epigenetic states that define distinct patterns of gene expression. Whereas sequence …

In recent years it has become evident that RNA interference-related mechanisms can
mediate the deposition and transgenerational inheritance of specific chromatin modifications …

Heterochromatic DNA domains have important roles in the regulation of gene expression
and maintenance of genome stability by silencing repetitive DNA elements and transposons …

Histone post-translational modifications (PTMs) are associated with epigenetic states that
form the basis for cell-type-specific gene expression,. Once established, histone PTMs can …

Piwi-interacting RNAs (piRNAs) are RNA effectors with key roles in maintaining genome
integrity and promoting fertility in metazoans. In Caenorhabditis elegans loss of piRNAs …

Nuclear RNAi is an important regulator of transcription and epigenetic modification, but the
underlying mechanisms remain elusive. Using a genome-wide approach in the fission yeast …

RNA interference (RNAi) refers to the ability of exogenously introduced double-stranded
RNA to silence expression of homologous sequences. Silencing is initiated when the …

Main conclusion This review will provide evidence for the indispensable function of these
elements in regulating plant development and resistance to biotic and abiotic stresses, as …
