Relationship between DNA methylation and histone acetylation levels, cell redox and cell differentiation states in sugarbeet lines.

In order to evaluate the permanent chromatin remodeling in plant allowing their high developmental plasticity, three sugarbeet cell lines (Beta vulgaris L. altissima) originating from the same mother plant and exhibiting graduate states of differentiation were analyzed. Cell differentiation has been estimated by the cell redox state characterized by 36 biochemical parameters as reactive oxygen species steady-state levels, peroxidation product contents and enzymatic or non-enzymatic protective systems.

DNA methylating and demethylating treatments modify phenotype and cell wall differentiation state in sugarbeet cell lines.

In plants organogenesis, cell differentiation and dedifferentiation are fundamental processes allowing high developmental plasticity. Such plasticity involved epigenetic mechanisms but limited knowledge is available concerning quantitative aspects. Three sugarbeet (Beta vulgaris L.
