Special Issue Information
Dear Colleagues,
Apomixis is one of the most intriguing traits observed in angiosperms, since it allows the formation of seeds containing embryos that are genetically identical to the mother plant by avoiding two key sexual reproduction processes: meiosis and fertilization. In combination, sexuality and apomixis establish a sophisticated reproductive strategy, consisting of the generation of variability through recombination and hybridization, followed by cloning and propagation through seeds of best adapted individuals who adapted the best. A similar scheme can be transferred to plant breeding programs to fix heterotic combinations and rapidly produce new varieties at low costs. However, in order to fully and responsibly harnessing apomixis into plant breeding, detailed knowledge on its underlying molecular mechanisms, as well as its connection with sexuality and polyploidy, is required. The molecular control of different apomixis mechanisms (apospory, diplospory, and adventitious embryony) has been intensively examined over the last two decades, and, recently, the major implicated pathways began to emerge. This Special Issue of Plants will welcome primary research papers and reviews focused on the genetic, epigenetic, and biochemical aspects that control apomixis in plants, as well as its impact in population and ecology dynamics and its link with sexuality and polyploidy. It will also highlight articles that prospectively explore the use of apomixis in breeding programs.

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.
