Epigenetic Regulation of Plant Stress Responses

Dear Colleagues,

Plants are sessile organisms subjected to constantly changing environments that can generate unfavorable or stressful situations for plant growth, development, and productivity. In recent years, enormous progress has been made in understanding epigenetic regulation in response to diverse environmental stimuli, including in response to biotic and abiotic stresses. Epigenetic regulation comprises the covalent modification of DNA and histone proteins that affect the accessibility of chromatin to the transcriptional machinery. The three main types of epigenetic marks or signatures include DNA methylation, histone modification, and non-coding RNA (ncRNA)-mediated RNA interference, including small RNAs and long non-coding RNAs. Furthermore, epigenetic mechanisms can generate stress memory, which can be transferred to the next generation of plants exposed to stress. In this way, knowledge of these stress memories could enhance our understanding of the processes implicated in the adaptation of plants to stress. This Special Issue of Plants aims to collect the latest data in the field of epigenetic regulation in response to various types of stress.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
