Special Issue Information

Dear Colleagues,

 

Grapevines are one of the longest domesticated plant species, and are among the most important fruit crops cultivated and consumed worldwide. Grapes have a rich genetic diversity and are traditionally conserved in genebanks, primarily as whole plants in the field. Field plantings are readily available for use in breeding programs and propagation; however, they are expensive and could be lost in the event of biological or environmental disasters. Considering that the gender of many cultivars is important for winemaking production, we can assume that different cultivars react differently in conditions of cultivation, maintenance, and also conservation itself. However, in some countries, certain cultivars present a part of national heritage, and need to be conserved because of the genetic variability of the gender in the terms of breeding activities. Complementary conservation strategies should be considered by genebanks to securely conserve collections of Vitis genetic resources for future requirements of breeding programs. In vitro technologies have demonstrated the potential for developing additional conservation strategies for grapevines.

Methods are based on slow growth storage and cryopreservation. In vitro storage under slow growth involves the application of media-reduced nutrients, lowering the photoperiod and incubation temperature (4–5°C), resulting in prolonged subcultures. The cultures remain in a condition where the cell metabolism is reduced, allowing medium-term conservation for a few months to years. Cryopreservation is freezing at ultralow temperatures using liquid nitrogen. Under cryopreserved conditions, the genetic integrity of the plant tissue is kept for an indefinite period of time, without any manipulations. It is also cost-effective to maintain collections for extended periods of time in liquid nitrogen, and it minimizes the risk of contamination compared with field or in vitro collections.

Reliable cryopreservation methods that result in high levels of regrowth after liquid nitrogen exposure are key to the development of successful base collections. Recent advances in grapevine cryopreservation using vitrification-based procedures appear to be promising in order to overcome species- and genotype-specific responses. This represents one of the major challenges for the widespread use of the cryopreservation procedure. The implementation of protocols requires prior validation of particular protocols to some groups of cultivars, and consequently the design of genebank for each repository.

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 papers will be 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 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 1800 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.
