Special Issue Information
Dear Colleagues,
Somatic embryogenesis is considered a fascinating example of the concept of cellular totipotency. During this regeneration process, one or a few somatic cells are subjected to favorable in vitro experimental conditions and undergo morphological and biochemical changes that prompt them to form bipolar structures, which are known as somatic embryos. Although gamete fusion does not take place, somatic embryos resemble zygotic embryos and have the ability to germinate and develop into somatic seedlings. In addition to the application of clonal propagation, embryogenic cultures represent excellent target materials for the insertion of isolated gene sequences into somatic cells and the subsequent production of genetically modified plants. This technology is expected to be replaced by the emerging field of plant genome editing, which will most likely utilize embryogenic cultures as a means of generating enhanced plants. In addition, the application of synthetic seed technology to somatic embryos is being considered with regard to storage and handling qualities. Somatic embryogenic lines can be subjected to well-developed cryopreservation techniques for the long-term conservation of plant diversity or conservation during the field testing of regenerated plants and the subsequent retrieval of superior lines from liquid nitrogen for their exploitation. Finally, the somatic embryogenesis process is an ideal system for studying the molecular mechanisms that regulate developmental plasticity in plants. All of these potential applications have made somatic embryogenesis a subject of great scientific interest.
We welcome the submission of manuscripts related to the overall topic of somatic embryogenesis and that address the following subtopics:
The factors that affect somatic embryogenesis, including stress stimuli, the endogenous content of auxins and cytokinins, the role of the explant type and its physiological state, and the role of exogenous plant growth regulators;
The anatomical and histological analysis of the somatic embryogenesis process;
- Androgenesis;
- Cryopreservation somatic embryos;
- Genetic transformation somatic embryos;
- Genome-editing somatic embryos;
- Synthetic seeds;
- Liquid culture: embryogenic suspensions and bioreactors;
- Gene expression during the somatic embryogenesis process;
- Epigenetic modifications: histone modification and DNA methylation.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
