Methylation of DNA and of histone 3 at Lys 9 (H3K9) are highly correlated with gene
silencing in eukaryotes from fungi to humans. Both of these epigenetic marks need to be …

RNA-directed DNA methylation (RdDM) is the major small RNA-mediated epigenetic
pathway in plants. RdDM requires a specialized transcriptional machinery that comprises …

Much of what we know about eukaryotic transcription stems from animals and yeast;
however, plants evolved separately for over a billion years, leaving ample time for …

Plant breeding has traditionally relied on combining the genetic diversity present within a
species to develop combinations of alleles that provide desired traits. Epigenetic diversity …

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 …

Background Polyploidy is a pervasive evolutionary feature of all flowering plants and some
animals, leading to genetic and epigenetic changes that affect gene expression and …

DNA methylation is a conserved epigenetic gene-regulation mechanism. DOMAINS
REARRANGED METHYLTRANSFERASE (DRM) is a key de novo methyltransferase in …

Transposable elements (TEs) are mobile units of DNA that comprise large portions of plant
genomes. Besides creating mutations via transposition and contributing to genome size, TEs …

Arabidopsis telomeric repeat binding factors (TRBs) can bind telomeric DNA sequences to
protect telomeres from degradation. TRBs can also recruit Polycomb Repressive Complex 2 …

Plants have short‐term stress memory that enables them to maintain the expression state of
a substantial subset of heat‐inducible genes during stress recovery after heat stress. Little is …
