About 65 years ago, reactive oxygen species (ROS) were found to be produced in photosynthesis (Mehler 1951), which has been called the Mehler reaction. Thereafter, Asada et al. (1973) showed the primary product of ROS superoxide radical (O2-). Many researchers have given the evidence that the Mehler reaction is enhanced under low photosynthetic efficiency conditions (e.g., induction phase of photosynthesis, low CO2 or high light). Research reports on ROS include (1) the scavenging system of ROS, (2) molecular mechanisms of ROS damages, (3) physiological functions and molecular mechanisms of ROS signals, (4) molecular breeding of plants having higher tolerance to ROS, and (5) recently, regulation mechanisms of ROS production in the Mehler reaction were elucidated. Photosynthesis organisms can not escape from the presence of O2. This is also true at night, when photosynthesis does not proceed. Because the activation of O2 to ROS favors conditions where electron is rich. That is, the electron transport system in mitochondria functions with ROS produced. O2 has two faces: The causal for oxidative stress as ROS and the causal for signal transduction as ROS. That is, (6) a full understanding of O2 chemistry contributes to the elucidation of how photosynthesis organisms have survived in the presence of O2 from the appearance of cyanobacteria on Earth. The Special Issue collects regular papers, reviews, opinions, etc., on topics (1)–(6). These recent stories open the readers to ROS world in photosynthesis organisms.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
