Plants Redox Biology

Dear Colleagues,

In recent years, the research of plant redox biology has expanded to all aspects of plant science. As an evolutionary consequence, plants have to maintain an optimal cellular and subcellular redox poise to continue normal metabolic activities, especially under certain stresses. For example, plants produce significant amounts of reactive oxygen species (ROS) as a result of photosynthetic electron transport and metabolism. In addition to the so-called deleterious effects of ROS, vital signaling roles of ROS in plant growth, development and stress responses have recently emerged. Notably, the main antioxidants, including glutathione, ascorbate, and others, are important plant redox components. Accumulating evidence points to the fact that redox signaling interfaces directly with the plant hormone network in the synergistic control of development and its modulation in response to environmental stresses. Furthermore, it is commonly accepted that ROS can cause post-translational modifications of proteins through oxidoreduction, indicating the influence of ROS beyond transcription and translation processes. Therefore, it is important to understand better the redox biology of plants with the aids of advanced genomics, transcriptomics, proteomics and metabolomics approaches towards stress resilience.

This Special Issue aims to collect research articles and review papers on biochemical and physiological aspects of thiol redox regulation, reactive oxygen/nitrogen species, and antioxidant metabolism in the context of plant growth, development, environmental acclimation, and stress responses; papers describing recent developments in the pervasive roles of redox signaling in plant development, integrating metabolism, and plant–environment interactions are especially welcome.

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 250 words) can be sent to the Editorial Office for assessment.

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.
