Methylome analysis reveals an important role for epigenetic changes in the regulation of the Arabidopsis response to phosphate starvation.

ABSTRACT: Phosphate (Pi) availability is a significant limiting factor for plant growth and productivity in both natural and agricultural systems. To cope with such limiting conditions, plants have evolved a myriad of developmental and biochemical strategies to enhance the efficiency of Pi acquisition and assimilation to avoid nutrient starvation. In the past decade, these responses have been studied in detail at the level of gene expression; however, the possible epigenetic components modulating plant Pi starvation responses have not been thoroughly investigated. Here, we report that an extensive remodeling of global DNA methylation occurs in Arabidopsis plants exposed to low Pi availability, and in many instances, this effect is related to changes in gene expression. Modifications in methylation p
