Noncoding RNA has long been proposed to control gene expression via sequence-specific
interactions with regulatory regions. Here, we review the role of noncoding RNA in …

MiroRNAs (miRNAs) are double-stranded, noncoding RNA molecules (with an average size
of 22bp) that serve as post-transcriptional regulators of gene expression in higher …

The enrichment of mobile genetic elements in heterochromatin may be due, in part, to
targeted integration. The chromoviruses are Ty3/gypsy retrotransposons with …

DNA methylation and histone methylation are two key epigenetic modifications that help
govern heterochromatin dynamics. The roles for these chromatin-modifying activities in …

Tandem DNA repeats are often organized into heterochromatin that is crucial for genome
organization and stability. Recent studies revealed that individual repeats within tandem …

Histone H3 lysine-9 methylation (H3K9me) is a hallmark of the condensed and
transcriptionally silent heterochromatin. It remains unclear how H3K9me controls …

In Caenorhabditis elegans, vulval cell-fate specification involves the activities of multiple
signal transduction and regulatory pathways that include a receptor tyrosine …

Abstract The LOSS OF APOMEIOSIS (LOA) locus is one of two dominant loci known to
control apomixis in the eudicot Hieracium praealtum. LOA stimulates the differentiation of …

Background Transposable element (TE)-related genes comprise a significant portion of the
gene catalog of grasses, although their functions are insufficiently characterized. The recent …

Genomic imprinting attracted particular attention in the 1980's following the discovery that
the parental origin of genetic information is essential for normal development of eutherians …
