Polyploids—organisms that have multiple sets of chromosomes—are common in certain
plant and animal taxa, and can be surprisingly stable. The evidence that has emerged from …

Epigenetics has become one of the hottest topics of research in plant functional genomics
since it appears promising in deciphering and imparting stress-adaptive potential in crops …

Living organisms have the clearly defined strategies of stress response. These strategies
are predefined by a genetic make-up of the organism and depend on a complex regulatory …

A large number of recent studies have demonstrated that many important aspects of plant
development are regulated by heritable changes in gene expression that do not involve …

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

Methylation of histone H3 lysine 9 (H3K9) is a hallmark of transcriptional silencing in many
organisms. In Arabidopsis thaliana, dimethylation of H3K9 (H3K9m2) is important in the …

The organization of DNA into chromatin regulates expression and maintenance (replication,
repair, recombination, segregation) of genetic information in a dynamic manner. The N …

Summary ARGONAUTE4 (AGO4) and RNA polymerase IV (Pol IV) are required for DNA
methylation guided by 24 nucleotide small interfering RNAs (siRNAs) in Arabidopsis …

The Arabidopsis KRYPTONITE gene encodes a member of the Su (var) 3-9 family of histone
methyltransferases. Mutations of kryptonite cause a reduction of methylated histone H3 …

Both DNA methylation and post‐translational histone modifications contribute to gene
silencing, but the mechanistic relationship between these epigenetic marks is unclear …
