Molecular Mechanisms Underlying Organ Symmetry in Plants

Dear Colleagues,

A paramount aspect of multicellular development is the establishment of ground (basic) symmetry types during organ formation, in concert with the polarity axes and tissue specification. The type of symmetry—bilateral, biradial, or radial—that an organ adopts during its development is strictly connected to its function. Ultimately, symmetry formation contributes to the fitness of organisms and their evolution by diversifying and adapting organ function to the environment. Therefore, unlocking the molecular mechanisms that underpin its regulation holds potential for understanding the underlying processes that allow multicellular organs to reach their perfectly optimized symmetric shape and organ function.

In this Special Issue, we aim to highlight and disseminate the state-of-the-art and latest findings about the fundamental molecular mechanisms underpinning symmetry establishment and transitions during plant organ development, as well as events of symmetry breaking and asymmetry that can be observed at every biological level, from cells to tissues, all the way to the organismal level. We also welcome mathematical modelling and evo-devo approaches to reach a comprehensive and multidisciplinary understanding in the study of symmetry in plant development and evolution.

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. Genes 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.
