MicroRNAs (miRNAs) are small RNAs that control gene expression through silencing of
target mRNAs. Mature miRNAs are processed from primary miRNA transcripts by the …

Regulatory small RNAs, which range in size from 20 to 24 nucleotides, are ubiquitous
components of endogenous plant transcriptomes, as well as common responses to …

Nucleosome remodelers of the DDM1/Lsh family are required for DNA methylation of
transposable elements, but the reason for this is unknown. How DDM1 interacts with other …

Introduction Darwin famously characterized the rapid rise and early diversification of
flowering plants (angiosperms) in the fossil record as an “abominable mystery.” Identifying …

Cytosine methylation is involved in various biological processes such as silencing of
transposable elements (TEs) and imprinting. Multiple pathways regulate DNA methylation in …

Ripening of tomato fruits is triggered by the plant hormone ethylene, but its effect is restricted
by an unknown developmental cue to mature fruits containing viable seeds. To determine …

RNA silencing is a central regulator of gene expression in most eukaryotes and acts both at
the transcriptional level through DNA methylation and at the post-transcriptional level …

Long noncoding RNAs (lncRNAs) have gained widespread attention in recent years as a
potentially new and crucial layer of biological regulation. lncRNAs of all kinds have been …

Plant genomes are the source of large numbers of small RNAs, generated via a variety of
genetically separable pathways. Several of these pathways converge in the production of …

Heterosis, also known as hybrid vigour, is widespread in plants and animals, but the
molecular bases for this phenomenon remain elusive. Recent studies in hybrids and …
