Plant cells accumulate small RNA molecules that regulate plant development, genome
stability, and environmental responses. These small RNAs fall into three major classes …

For decades, transposable elements have been known to produce a wide variety of changes
in plant gene expression and function. This has led to the idea that transposable element …

RNA-directed DNA methylation (RdDM) is a biological process in which non-coding RNA
molecules direct the addition of DNA methylation to specific DNA sequences. The RdDM …

Cytosine DNA methylation (mC) is a genome modification that can regulate the expression
of coding and non-coding genetic elements. However, little is known about the involvement …

In contrast to the majority of animal species, plants are sessile organisms and are, therefore,
constantly challenged by environmental perturbations. Over the past few decades, our …

Identification of alleles that improve crop production and lead to higher-yielding varieties are
needed for food security. Here we show that the quantitative trait locus WFP (WEALTHY …

Background The growing wealth of knowledge on whole-plant genome sequences is
highlighting the key role of transposable elements (TEs) in plant evolution, as a driver of …

DNA methylation is an important epigenetic mark involved in diverse biological processes.
In plants, DNA methylation can be established through the RNA-directed DNA methylation …

RNA-directed DNA methylation in Arabidopsis thaliana depends on the upstream synthesis
of 24-nucleotide small interfering RNAs (siRNAs) by RNA POLYMERASE IV (Pol IV), and …

The function of plant genomes depends on chromatin marks such as the methylation of DNA
and the post-translational modification of histones. Techniques for studying model plants …
