SWI/SNF chromatin remodeling and linker histones in plants.
In yeast and mammals, ATP-dependent chromatin remodeling complexes belonging to the SWI/SNF family play critical roles in the regulation of transcription, cell proliferation, differentiation and development. Homologs of conserved subunits of SWI/SNF-type complexes, including several putative ATPases and other core subunits, have been identified in plants. Here I summarize recent insights in structural organization and functional diversification of putative plant SWI/SNF-type chromatin remodeling complexes and discuss in a broader evolutionary perspective the similarities and differences between plant and yeast/animal SWI/SNF remodeling. I also summarize the current view of localization in nucleosome and dynamic behaviour in chromatin of linker (H1) histones and discuss significance of recent findings indicating that in both plants and mammals histone H1 is involved in determining patterns of DNA methylation at selected loci.
