Special Issue Information
Dear Colleagues,
The dynamic and flexible processes of plant growth and development, even with the greatest compliance, generate reactive oxygen species (ROS), primarily in chloroplasts, mitochondria, and peroxisomes. ROS can be significant inhibitors of photosynthetic processes through the inhibition of CO2 fixation, and can lead to the formation of cytotoxic lipid aldehydes, alkenes, malondialdehyde (MDA), as well as the deactivation of Calvin cycle enzymes. Although their harmful effects have been confirmed, ROS can also act as signaling molecules and secondary messengers, so coordinating the process of ROS production and their elimination in the cellular environment enables adequate signaling reactions, including enzyme activation and gene expression. The increased concentrations of ROS can lead to significant damage to nucleic acids and carbohydrates, protein oxidation, and lipid peroxidation, resulting in oxidative stress. The highly sophisticated antioxidant mechanism allows plant cells to overcome impaired redox homeostasis and stress-induced damage. The current Special Issue attempts to summarize the most recent knowledge of stress mitigation through antioxidant activation, as well as the opportunities for specific classes of antioxidants to contribute to plant redox homeostasis. Since coordinated changes occur at several levels of plant organization, studies regarding the differences in the location and biochemical properties of antioxidants resulting in an adaptable and flexible antioxidant system are highly appreciated, together with integrative approaches in improving plant growth and development.

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. Cells is an international peer-reviewed open access semimonthly 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.
