Special Issue Information
Dear Colleagues,
As sessile organisms, plants are continuously exposed to environmental stresses such as high light, drought, and extreme temperatures. The production of reactive oxygen species (ROS) is enhanced by these environmental stimuli through the perturbation or activation of the primary metabolisms, such as photosynthesis, photorespiration, and respiration. Although ROS are reactive forms of molecular oxygen and potentially toxic to plant cells, they have another role as signaling molecules that modulate a wide range of biological processes, including defense systems, programmed cell death, and growth and development. To support these signaling roles, plants have several oxidases that catalyze the one-electron reduction of molecular oxygen, such as NADPH oxidases, as alternative intra- and extracellular sources of ROS. The balance of ROS actions as cytotoxic and signaling molecules is therefore critical for the plant stress acclimation process. This balance is fine-tuned through highly sophisticated mechanisms that control the production and scavenging of ROS under environmental stress.
In this Special Issue, we invite high-quality original papers and reviews that describe recent advances in the plant ROS field. Potential topics will include (but are not limited to) the following: (1) regulation of ROS production, (2) ROS scavenging/antioxidant systems, and (3) ROS sensing and signaling in plants. We look forward to 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 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. Antioxidants 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 2900 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.
