Special Issue Information
Dear Colleagues,
Plant micropropagation is a powerful tool for cloning and the ex situ conservation of endangered species, as well as for the large-scale production of selected and economically relevant genotypes and varieties. The de novo organogenesis of roots is a crucial step in vegetative propagation systems. However, adventitious rooting is often a limiting factor of in vitro propagation, particularly for difficult-to-root species, and it remains one of the most challenging issues in the successful production of plants.
Adventitious root formation includes the reprograming of somatic cells, which change their fate towards the establishment of root founder cells (induction phase), followed by the development of adventitious root primordia (formation phase), and finally root emergence (expression phase). In vitro root regeneration is affected by external and endogenous factors, such as wounding, etiolation, genotype, maturation of the mother explant, plant growth regulators, and basal culture medium, among others. Additionally, de novo root organogenesis is regulated through molecular mechanisms like gene expression, transcription factors, hormone signaling, and epigenetic regulation. Plant acclimatization is also an important factor for in vitro plan production.
In this Special Issue, you are invited to share your research on advances in the adventitious root formation of in vitro cultures, plant acclimatization, and the understanding of the molecular mechanisms underlying root regeneration and root development.

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.
