Chromatin remodeling in plant development.
Plant development results from specific patterns of gene expression that are tightly regulated in a spatio-temporal manner. Chromatin remodeling plays a central role in establishing these expression patterns and maintaining epigenetic transcriptional states through successive rounds of mitosis that take place within a cell lineage. Plant epigenetic switches occur not only at the embryo stage, b...
متن کاملChromatin Remodeling ATPases and Plant Development
ATP-dependent chromatin remodeling is an important facet of the regulation of gene expression in eukaryotes. Assembly of DNA into nucleosomes, the basic unit of chromatin, restricts the accessibility of cisregulatory elements in the core DNA for transcription factors that recognize and bind these sites. Chromatin remodeling ATPases use the energy derived from ATP hydrolysis to induce conformati...
متن کاملRemembrance of things past: chromatin remodeling in plant development.
Chromatin remodeling in plants has usually been discussed in relation to aspects of genome defense such as transgene silencing and the resetting of transposon activity. The role of remodeling in controlling development has been less emphasized, although well established in animal systems. This is because cell fate in plants is often held to be entirely specified on the basis of position, appare...
متن کاملChromatin-remodeling and memory factors. New regulators of plant development.
The establishment and heritable maintenance of specific epigenetic states that lead to differential gene expression are crucial for cell differentiation and development. Over the past few years, it has become apparent that epigenetic control of transcription is mediated through specific states of the chromatin structure. Therefore, changes in the chromatin structure associated with activation a...
