Special Issue Information
Dear Colleagues,
Managing cultivar-specific interactions with environment remains a major challenge for crop production. Epigenetics generally refers to changes in gene expression not resulting from alterations in the primary DNA sequence, with many fundamental mechnisms identified and characterised in plants. This includes epigenetic marks of genomic DNA methylation and histone modification that affect chromatin conformation and are involved in processes such as RNA-directed DNA methylation (RdDM), programmed demethylation, parental imprinting and transposon activation/deactivation. Meanwhile, diverse developmental and response phenomena are affected by processes such as miRNA and lncRNA signalling and regulation, and RNAi interference.
Many crop plants have complex genomes of polyploid origin, a high load of transposons and DNA methylation, and have evolved to co-opt epigenetic processes into various aspects of development, mediating responses to environmental cues. Whilst epigenetics has become integral to understanding and managing numerous human conditions and diseases, progress has been slower in translating insights into practical outcomes for crop breeding and production.
Within this issue, we aim to highlight how translational research may contribute to the development of resilient and responsive crop cultivars, as well as epigenetic interventions that may become integral to crop production and protection. We therefore call for papers that represent the range of current and potential opportunities within this active research field.

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. Agronomy is an international peer-reviewed open access monthly 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 2600 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.
