Chromatin modifiers that control plant development.

The different cell types of a multicellular organism express different sets of genes. Although this is one of the oldest paradigms of developmental genetics, how different patterns of gene expression are established and maintained during subsequent cell division is an active topic of research. Chromatin modifiers play an essential role in controlling gene expression and in establishing epigenetic marks that can be inherited. During the past few years, large number of putative chromatin-associated proteins have been uncovered as controllers of meristem organization and activity, phase transition, and gametophyte and embryo development.
