Special Issue Information
Dear Colleagues,
Nitric oxide (NO) and reactive oxygen species (ROS) are now recognized as fundamental signaling molecules in plant biology, governing a wide spectrum of physiological and metabolic processes. Once considered merely toxic intermediates, these reactive species—together with reactive sulfur species (RSS)—form a complex redox network that finely tunes plant growth, development, and responses to environmental challenges. Their tightly regulated interplay determines redox homeostasis, modulates cellular signaling cascades, and influences transcriptional and post-translational control in both physiological and stress conditions.
Emerging evidence highlights that NO and ROS act synergistically or antagonistically to modulate hormonal signaling, ion balance, and antioxidant defense, thereby shaping plant adaptation to salinity, drought, heat, and pathogen attack. Moreover, post-translational modifications such as S-nitrosylation, sulfenylation, and tyrosine nitration have been identified as critical mechanisms linking reactive species metabolism to gene expression and protein function. Advances in omics technologies, molecular genetics, and imaging have accelerated our understanding of these dynamic redox interactions, opening new perspectives for improving crop resilience and productivity through redox-based strategies.
This Special Issue, “Nitric Oxide and Reactive Species in Plant Physiology and Pathology,” welcomes original research and comprehensive reviews that elucidate the biochemical, molecular, and physiological roles of NO, ROS, and RSS. Studies exploring their crosstalk with phytohormones, signaling pathways, and plant defense systems are particularly encouraged.

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. Biomolecules 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 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.
