The growth conditions in different latitudes vary markedly with season, day length, light
quality and temperature. Many plant species have adapted well to the distinct environments …

Highlights•Stress response in plants involves chromatin re-organization.•This includes
changes in nuclear structure, histone variants, chaperones, and modifications.•Chromatin …

Epigenetic factors determine responses to internal and external stimuli in eukaryotic
organisms. Whether and how environmental conditions feed back to the epigenetic …

Plants, as sessile organisms, need to sense and adapt to heterogeneous environments and
have developed sophisticated responses by changing their cellular physiology, gene …

Imprinted gene expression occurs during seed development in plants and is associated with
differential DNA methylation of parental alleles, particularly at proximal transposable …

Abstract PHYTOCHROME INTERACTING FACTOR3 (PIF3) is a key basic helix-loop-helix
transcription factor of Arabidopsis thaliana that negatively regulates light responses …

Heat stress affects epigenetic gene silencing in Arabidopsis. To test for a mechanistic
involvement of epigenetic regulation in heat-stress responses, we analyzed the heat …

Nitric oxide (NO) is a signaling molecule with multiple regulatory functions in plant
physiology and stress response. In addition to direct effects on transcriptional machinery, NO …

Plants interact with their environment by modifying gene expression patterns. One
mechanism for this interaction involves epigenetic modifications that affect a number of …

The plant circadian clock promotes daily rhythms in the activity of many processes. These
rhythms are synchronized to the diurnal day/night cycle by environmental cues such as light …
