Overlapping epigenetic mechanisms have evolved in eukaryotic cells to silence the
expression and mobility of transposable elements (TEs). Owing to their ability to recruit the …

Gene silencing is a negative feedback mechanism that regulates gene expression to define
cell fate and also regulates metabolism and gene expression throughout the life of an …

Eukaryotes contain a diversified set of small RNA-guided pathways that control genes,
repeated sequences, and viruses at the transcriptional and posttranscriptional levels …

Epigenetic silencing is a natural phenomenon in which the expression of genes is regulated
through modifications of DNA, RNA, or histone proteins. It is a mechanism for defending host …

DNA methylation can play important roles in the regulation of transposable elements and
genes. A collection of mutant alleles for 11 maize (Zea mays) genes predicted to play roles …

Background Computational analysis of cDNA sequences from multiple organisms suggests
that a large portion of transcribed DNA does not code for a functional protein. In mammals …

High-throughput sequencing has revealed that the majority of RNAs have no capacity to
encode protein. Among these non-coding transcripts, recent work has focused on the roles …

Small RNAs from plants are known to be highly complex and abundant, with this complexity
proportional to genome size. Most endogenous siRNAs in Arabidopsis are dependent on …

Eukaryotic gene expression is regulated at least by two processes, RNA interference at the
post-transcriptional level and chromatin modification at the transcriptional level. Distinct …
