Genome-wide analysis of DNA methylation in response to light and salt stress in a halophyte with single cell C4 pathway

This study revealed a stress-induced genome-wide DNA hypo-methylation in S. aralocaspica. SaPEPC1 and SaPEPC2 exhibited distinct methylation responses to darkness and salt stress, respectively. Through methylation alteration experiments, we established the associations between DNA methylation and relevant gene expression, which should improve our understanding of epigenetic regulation in halophyte stress adaptation.
