Special Issue Information
Dear Colleagues,
Being sessile organisms, during their evolution, plants have developed a sophisticated chemical defense system to cope with environmental biotic and abiotic stressors. Reactive oxygen species (ROS) production is a common feature of plant responses to environmental stresses, arising both from their role as stress signaling molecules and from their release as by-products of disrupted metabolic pathways. Antioxidant molecules, both enzymatic and non-enzymatic, are either produced constitutively or induced to counteract the negative effects of ROS. Plant antioxidants, produced as a defense mechanism, also have a great range of applications for their beneficial effects on human health. This Special Issue aims to provide a collection of research articles or reviews exploring the production of plant metabolites with antioxidant properties in response to environmental stresses, from classical (drought, salinity, cold/frost, heat, pathogens) to emerging stress factors (air pollutants, micro-/nanoplastics, climate extremes, invasive pests). Studies proposing agronomic and molecular strategies to alleviate oxidative stress for enhanced crop yield and nutraceutical value are also welcome.

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.
