Special Issue Information
Dear Colleagues,
Antioxidants are the main defense of living organisms against cellular oxidative damage initiated by free radicals. Free radicals occur as a result of either normal metabolism or oxidative stress produced by environmental conditions, and accumulation of a high level of free radicals can generate cell damage and even DNA damage in the absence of antioxidants that are capable to quench them. Antioxidative mechanisms are highly specific; plants have a complex antioxidative system, including both enzymatic and nonenzymatic compounds, explicitly expressed during plants’ lifecycle since they are exposed to various environmental stress-inducing sources. Comprehension of antioxidants’ involvement in mechanisms of reactive oxygen species regulation is important in order to modulate the conditions ensuring normal plant growth. It is worth mentioning that, at the same time, plants are the main source of antioxidants used in human nutrition, and they are currently widely used in nutrition of precision. Therefore, studies on the role of antioxidant supplements, as well as the role of gene variability in oxidative stress in relation to nutrigenomics are welcome.
In this Special Issue, we shall present state-of-the-art knowledge around antioxidants and their role in regulation mechanisms of oxidative stress in plants and humans through classic and/or molecular genetic assessment, as well as their beneficial role in human nutrition.

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. Life 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.
