Special Issue Information
Dear Colleagues,
Embryogenesis plays a crucial role in the life cycle of plants. The fusion of the haploid female (egg cell) and male (sperm) gametes gives rise to a diploid zygote (the first cell of the sporophytic generation). The zygote possesses the ability to initiate embryogenesis, a developmental program that leads to the establishment of an embryo with the basic features of the adult body plan. Some of the embryological characters, such as types of embryogenesis, shape and structure of embryo, suspensor and haustoria, are important for establishing phylogenetic relationships between taxa. Studies on embryogenesis have relevance to the developmental and molecular biology.
Therefore, embryogenesis is an important process in creating a new generation. It comprises three elements: establishment of organization as an embryo, accumulation of food reserves in the embryo, and acquisition of desiccation tolerance and seed dormancy. These elements are accurately regulated by many factors, including phytohormones, proteins, transcription factors, and other substances associated with embryogenesis. Furthermore, successful embryogenesis is essential for plant fertility and reproductive efficiency.
Despite intense investigation, there are still open questions and challenges on this fascinating field. The methods to study plant embryogenesis have undergone a rapid evolution over the past decade. Many of the processes that underline embryogenesis are beginning to be understood, but there are still many questions that need to be answered. For example, our knowledge is still largely unknown about the regulatory mechanisms of various embryonic events at all levels. Understanding the genetic programs operating in the embryo is important not only for plant evolution but also for plant breeding and biotechnology.
Therefore, this Special Issue is open to original research papers, reviews, and other forms of scientific communication that increase our fundamental understanding of plant embryogenesis and its regulation, including genome, epigenome, transcriptome, proteome, and metabolome. All studies at the structural, genetic, biochemical, and molecular levels in many different types of plants (both in model and non-model plants) are most welcome.

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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
