Since the human genome was sequenced, the term" epigenetics" is increasingly being
associated with the hope that we are more than just the sum of our genes. Might what we …

Noncoding RNAs have emerged as major components of the eukaryotic transcriptome.
Genome-wide analyses revealed the existence of thousands of long noncoding RNAs …

Highlights•Multiple mechanisms exist to repress the mutagenic potential of transposable
element (TE) activity.•Transcriptionally active TEs trigger normally latent pathways including …

Paramutation describes a process that results in heritable epigenetic changes of gene
regulation and trans-homologue interactions. Recent discoveries in model organisms have …

China has to feed 20% of the global population with only about 5% of the planet's water
resources and 7% of its arable land. With such limited natural conditions, however, China's …

Genome-wide approaches to the study of hybrid vigor have identified epigenetic changes in
the hybrid nucleus in Arabidopsis (Arabidopsis thaliana), maize (Zea mays), and rice (Oryza …

Abstract In Arabidopsis (Arabidopsis thaliana), DNA-dependent RNA polymerase IV (Pol IV)
is required for the formation of transposable element (TE)-derived small RNA transcripts …

Paramutation is a transfer of heritable silencing states between interacting endogenous
alleles or between endogenous alleles and homologous transgenes. Prior results …

Core promoters are crucial for gene regulation, providing blueprints for the assembly of
transcriptional machinery at transcription start sites (TSSs). Empirically, TSSs define the …

All eukaryotes use three DNA-dependent RNA polymerases (RNAPs) to create cellular
RNAs from DNA templates. Plants have additional RNAPs related to Pol II, but their …
