Special Issue Information
Dear Colleagues,
Photorespiration, a plants-specific metabolism, is initiated by the oxygenase reaction of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), which competes with the carboxylase reaction for CO2 assimilation. Both photorespiration and CO2 assimilation are driven by chemical energy from photosynthetic electron transport. Photorespiration reduces the energy efficiency of photosynthesis and is often considered a wasteful pathway. However, under suppression of CO2 assimilation by environmental stress (so-called oxidative stress conditions), it functions as an alternative energy sink to avoid electron accumulation in the electron transport chain which can result in the generation of reactive oxygen species (ROS) and oxidative damages in photosynthetic machineries. In addition, photorespiration is one of the ROS-generating process in plant metabolic pathways, which suggests to be a signaling pathway for oxidative stress.
The understanding of photorespiration in plants has advanced significantly and multiple roles have been proposed. This Special Issue “Photorespiration and Reactive Oxygen Species (ROS)” aims to further update our knowledge about photorespiration, especially focusing on the relationship with oxidative stress. We welcome the latest research in physiology, biochemistry, and comprehensive omics analysis, as well as multifaceted reviews to date.

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.
