Reactive Oxygen Species and Reactive Carbonyl Species in Plants

Dear Colleagues,

Photosynthetic activities always carry the risk of oxygen activation, producing reactive oxygen species (ROS), which is considered inevitable. ROS significantly impact biological activities in two ways: high ROS levels cause oxidative damage to cells, while the ROS molecules act as essential signals for the acclimation of plants to survive ever-changing (and sometimes harsh) environmental conditions. The intracellular ROS concentrations thus need to be tightly controlled; for example, the production of ROS in photosystem I is essentially suppressed in response to photosynthetic activity. On the other hand, ROS generates secondary reactive molecules, i.e., reactive carbonyl species (RCS), via the oxidation of membrane lipids. RCS molecules, like ROS, bring about cellular injury and carry oxidative signals, but RCS is more diverse than ROS and variable by organelles, tissues, and stress conditions. A novel concept that RCS molecular specificity plays a role in organelle-specific regulation has arisen. This Special Issue will comprise papers addressing the following topics, aimed at uncovering how photosynthetic organisms have overcome the challenge of O₂ in the face of ROS generation as the atmospheric environment became increasingly oxygen-rich:

1. ROS production in photosynthetic organisms and mechanisms for its suppression;
2. Molecular mechanisms for ROS signal detection and acquisition of oxidative injury resistance;
3. Diversity of RCS generation reactions and the mechanisms for suppressing them;
4. Molecular mechanisms for RCS sensing and the avoidance of RCS-induced injury.

Submitted papers will undergo rigorous evaluation by our review system, and outstanding contributions will be selected for publication.

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.
