Special Issue Information
Dear Colleagues,
Secondary metabolites in grapevine vegetative and generative organs involve the production of various specialized compounds with important ecological and physiological roles.
Carotenoids and polyphenols are essential protectors of photosynthetic apparatus through the absorption of high-energy photons, neutralization of reactive oxygen species and dissipation of excess energy. Flavonoids and proanthocyanidins are defense compounds that deter herbivores and inhibit the oviposition of eggs or the growth of pathogen microorganisms. Resveratrol and other stilbene compounds act as phytoalexins. Anthocyanins, monoterpenes, and sesquiterpenes have important evolutionary roles, as attractant compounds for pollinators and beneficial insects and birds.
The quantity and composition of secondary metabolites are influenced by variety, agroecological conditions and factors related to abiotic and biotic stress. These compounds are essential for the sensory experience (color, flavor, and fragrance) of the berries, juice, and wine, and differences between varieties and vintages of wines. Viticulturists and oenologists carefully manage the synthesis and extraction of those compounds to achieve the desired flavor and aroma profiles for their products.
Recent advances in genomics and biotechnology have a profound impact on understanding and manipulating the biosynthesis of secondary metabolites in grapevine.
The present Special Issue welcomes original research articles and reviews that delve into the biosynthesis, regulation, and diversity of secondary metabolites, the impact of different agroecological conditions and biotic interactions on the synthesis of those compounds, and strategies for optimizing grape and wine quality.

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. Agronomy 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.
