Reactive oxygen species (ROS) designates O2-derived reactive molecules including the superoxide anion radical, hydrogen peroxide, singlet oxygen, and the hydroxyl radical. The critical significance of ROS in various aspects of plant life—ranging from the reprogramming during development to the defense response against stress and programmed cell death—is well accepted, and the terms ‘oxidative stress’ and ‘ROS signaling’ are now very often seen in articles in plant sciences. On the other hand, our understanding of the mechanisms of ROS action has been hampered by the nature of ROS in cells: they have high reactivity and their levels are kept very low by abundant antioxidants. The current study of ROS in plants and animals presents many challenges, for example: (i) In which cell compartments (or membranes) are distinct ROS produced and where do they react with their targets? (ii) Is an observed increase in ROS level the cause of cell damage or just a resulting symptom of it? (iii) In ROS-mediated signaling, how can ROS, rather universal species, induce a response specific to the original stimulus? (iv) What is the identity of ROS signal receptors and sensors? (v) By what biochemical mechanisms are ROS signals recognized and transmitted? (vi) How can ROS signal be allowed to travel among organelles and even cells, in a situation in which cells are filled with antioxidants? (vii) What biochemical factors determine cell’s fate, i.e., defense (survival) or death, upon ROS stimulus?
To improve our understanding, several breakthroughs in technology and in knowledge are required. In this Special Issue, we would like to invite research articles and reviews that tackle these challenges and explore new horizons of ROS study in plants.

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 papers will be 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. Plants 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 1200 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.

Title: Oxygen and ROS in Photosynthesis
Authors: Sergey Khorobrykh, Heta Mattila, Vesa Havurinne and Esa Tyystjärvi
Affiliation: Department of Biochemistry / Molecular Plant Biology, University of Turku, FI-20014 Turku, Finland
Abstract: Oxygen is a natural acceptor of electrons in the respiratory pathway of aerobic organisms and in many other biochemical reactions. Aerobic metabolism is always associated with the formation of reactive oxygen species (ROS). ROS may damage biomolecules but are also involved in regulatory functions of photosynthetic organisms. The review presents the main properties of ROS, the formation of ROS in the photosynthetic electron transport chain and in the stroma of chloroplasts, and ROS scavenging systems of thylakoid membrane and stroma. Effects of ROS on the photosynthetic apparatus and their roles in redox signaling are discussed.
Key words: reactive oxygen species; chloroplasts; photosynthetic electron transport chain; photodamage; redox signaling
