Special Issue Information

Dear Colleagues,

The greatest challenge for winegrowers currently is combining improved yield and fruit quality with the minimization of management cost and environmental impact. In recent decades, climate change has enhanced temperatures and reduced water availability, resulting in an earlier onset of phenological stages, severe yield losses, and altered grape quality. Grapevine performance and fruit quality can be assessed according to destructive and non-destructive methods for measuring several parameters such as yield, grape composition, and health status. Due to a rising number of geomatics, variable rate technologies, and robotics and artificial intelligence solutions, novel technologies based on rapid, cost-effective and non-destructive tools have become available to support winegrowers in the movement towards digital agriculture. Moreover, new cultural practices concerning canopy and floor management can help growers improve grapevine performance and vineyard efficiency. The aim of the current Special Issue is to disclose case studies describing a wide range of methods and tools developed worldwide to improve grapevine performance and fruit quality under a climate change scenario, with special emphasis on the application of digital technologies.

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. Horticulturae 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 2200 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.

The plant growth regulator ethylene influences rachis browning in grape (Vitis vinifera L.). Although the ethylene signaling pathway is well defined, there is limited knowledge on its mode of action during rachis browning. Here, we show that an ethylene response factor (VvERF111) positively regulates chlorophyll degradation in rachis by binding to a DRE motif in the promoter of VvCLH1. The expression of VvERF111 and VvCLH1 in rachis was induced by ethylene and inhibited by 1-methylcyclopropene (1-MCP). VvERF111 belongs to the ERF IX subfamily of the APETALA2/ethylene responsive factor (AP2/ERF) superfamily, shows transcriptional activity in yeast, and is localized in the nucleus and membrane. The transient overexpression of VvERF111 or chlorophyllase (VvCLH1) in grape leaves accelerated chlorophyll degradation. In VvERF111-overexpressing leaves, transcript levels of VvCLH1 were also increased. Our findings offer a deeper understanding of the transcriptional regulation of chlorophyll degradation during the rachis browning of grape. Full article
