Special Issue Information
Dear Colleagues,
Polyploidy or whole-genome duplication is a prominent evolutionary feature of all flowering plants and some animals. Many important crops including wheat, cotton, and oilseed rape are allopolyploids, which usually arise via the fusion of unreduced gametes between species or by interspecific hybridization followed by chromosome doubling. Genome redundancy and intergenomic interactions created by polyploidy offer evolutionary flexibility and phenotypic diversity for plant species, accompanied by rapid and dynamic changes in genomic structure and gene expression. Growing evidence suggests that epigenetic modifications including DNA methylation and histone modifications are also involved in the reprogramming of transcriptome networks, which allows polyploids to establish new cytotypes and promote adaptation in local environments. As many conclusions about epigenetic regulation in polyploidy are obtained from results using relatively few polyploid species, questions remain to be answered regarding the role of epigenetic regulation in polyploidy. This Special Issue of Plants will highlight the distribution and diversity of epigenetic modifications in polyploid plants, and their role in gene expression during polyploid evolution and domestication.

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.
