Epigenetic gene regulation by plant Jumonji group of histone demethylase

Histone methylation plays an important role in epigenetic regulation of gene expression. Reversible methylation/demethylation of several histone lysine residues is mediated by distinct histone methyltransferases and histone demethylases. Jumonji proteins have been characterized to be involved in histone demethylation. Plant Jumonji homologues are found to have important functions in epigenetic processes, gene expression and plant development and to play an essential role in interplay between histone modifications and DNA methylation.
