Special Issue Information
Dear Colleagues,
Plants, being sessile organisms, need to adapt to and survive harsh environmental conditions. Abiotic stresses such as drought, salinity, and extreme temperature negatively impact the yield and quality of crops. Studies using model plants suggest that plants can coordinate different signal transduction pathways to sense and respond to stress, including the generation of oxygen radicals and their derivatives. More importantly, reactive oxygen species (ROS) are generated in various cellular compartments by different cellular metabolisms. At lower concentrations, ROS serve as signaling molecules and play a vital role in plant defense. In contrast, the excessive generation of ROS can result in oxidative stress in plants. Therefore, the regulation of ROS under abiotic stress is vital for plant defense. Plants are protected from stress-induced oxidative damage by their antioxidant defense systems, which detoxify ROS and balance ROS generation under stressful conditions. These modifications help to alter the rate and efficiency of plant metabolism and photosynthesis, thus helping plants to adapt to and survive stressful environments. In this Special Issue, we aim to publish articles that provide a deeper understanding of the ROS and/or antioxidant regulation mechanisms under abiotic stress in plants. Articles focusing on ROS-regulated cellular, molecular, and physiological mechanisms used by plants to recognize and respond to specific or diverse abiotic stresses are also welcomed. This Special Issue will accept original research papers, methods, reviews, and perspectives.

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. Plants 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.
