Special Issue Information
Dear Colleagues,
Plant secondary metabolites consisting of terpenes (essential oil components, pyrethrins, limonoides, phytoecdysones, cardenolides, and saponins), phenolic compounds (phenol propanoids, coumarins, flavonoids, anthocyanins, and tannins), and nitrogen-containing compounds (alkaloids, cyanogenic glycosides, glucosinolates, and non-protein amino acids) have widely diverse chemical structures with different chemical properties and correspondingly exhibit diverse biological activities. Secondary metabolites can function in plant defense as deterrents against herbivorous and pathogenic organisms; in allelopathy, by reducing the germination and growth of competing plants; in attracting pollinators and animals, thereby aiding the production and dispersion of seeds; and in encountering biotic and abiotic stresses in the plant’s environment. In addition, isolated secondary metabolites can play important roles in medicine and nutrition.
This Special Issue will focus on studies that explore the following: the isolation and characterization of plant secondary metabolites; the effects of biotic and abiotic factors on the synthesis of metabolites; novel methods for detecting metabolites and analyzing metabolic pathways; the role of secondary metabolites in plant–environment interactions and their biodiversity; and novel uses in nutritional, medicinal, and cosmetic applications.
Climate change creates stressful conditions for plants and threatens crop survival and productivity. Therefore, studies on the role of secondary metabolites in the mitigation of stress and diseases are especially welcome. In addition, studies exploring the analysis of genetic resource diversity and the selection of plants with great potential to advantageously interact with the changing environment (such plants may also be beneficial in dietary and medicinal applications) are also very welcome.
We look forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.
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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metabolites 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 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.
