About this Research Topic
Upon environmental stress exposure and induction of the appropriate molecular response(s), genome and epigenome organization must be restored. In other words, chromatin shape/architecture has to be reestablished allowing accuracy in the regulation of transcription and also in genome 3D organization. Indeed, expression of protein coding genes must be reset-and mobilization of transposable elements (TE) must be fine-tuned to prevent dramatic changes in developmental programs and in genome structure, respectively. Moreover, most of the DNA repair pathways used to repair environmentally-induced DNA damage are DNA synthesis-dependent repair processes (i.e. excision repair pathways, homologous recombination). Thus, in addition to the need of accuracy during DNA synthesis to maintain genetic information integrity, the epigenomic landscape should also be efficiently and accurately restored. Altogether, more and more studies are providing accumulating evidence that pathways involved in the maintenance of genome and epigenome integrity have to be tightly coordinated.
In line with these observations, this Research Topic proposes to focus on genome and epigenome surveillance processes that are mobilized under environmental stresses. We welcome Original Research, Review and Perspective articles on, but not limited to, the following aspects in response to abiotic stress conditions:
- Epigenetic integrity during DNA damage, DNA repair and DNA replication
- DNA repair in the context of different chromatin landscapes
- Chromatin dynamics in responses to environmental stresses
- Epigenetic mechanisms of telomere homeostasis
- Epigenetic mechanisms regulating constitutive heterochromatin
- Transposon activation upon environmental stresses exposure
- DNA damage and repair upon environmental stresses exposure
This Research Topic aims to collect contributions to EpiPlant 2019, the Plant Epigenetics Meeting, held in Strasbourg, France, on 6th-8th February 2019. We also welcome external submissions to cover exciting new discoveries in the field.
