Small RNAs of 20–30 nucleotides guide regulatory processes at the DNA or RNA level in a
wide range of eukaryotic organisms. Many, although not all, small RNAs are processed from …

Transposable elements make up a substantial proportion of most plant genomes. Because
they are potentially highly mutagenic, transposons are controlled by a set of mechanisms …

MicroRNAs (miRNAs) are a class of regulatory RNAs of∼ 21 nucleotides that
posttranscriptionally regulate gene expression by directing mRNA cleavage or translational …

Mutations in the Arabidopsis ROS1 locus cause transcriptional silencing of a transgene and
a homologous endogenous gene. In the ros1 mutants, the promoter of the silenced loci is …

The maize genome is relatively large (∼ 2.3 Gb) and has a complex organization of
interspersed genes and transposable elements, which necessitates frequent boundaries …

The SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE (SPL) family of transcription factors
is functionally diverse, controlling a number of fundamental aspects of plant growth and …

Plants and filamentous fungi share with mammals enzymes responsible for DNA
methylation. In these organisms, DNA methylation is associated with gene silencing and …

▪ Abstract In many eukaryotes, including plants, DNA methylation provides a heritable mark
that guides formation of transcriptionally silent heterochromatin. In plants, aberrant RNA …

To address the role of small regulatory RNAs in rice development, we generated a large
data set of small RNAs from mature leaves and developing roots, shoots, and …

Epigenetic modifications are widely accepted as playing a critical role in the regulation of
gene expression and thereby contributing to the determination of the phenotype of …
