Nitric Oxide Signalling in Plants

Dear Colleagues, 

Nitric oxide (NO) is a gaseous small molecule and as a free radical, it plays important roles in various physiological and biological processes in plants. NO also acts as signal molecule and transducer with a range of functions, including seed germination, growth, root development, ripening and plant aging. The study of NO biology in plants during the last few decades has proved the beneficial role of NO in plant growth, but also the toxic byproducts of oxidative metabolism when exposed to abiotic/biotic stresses. Some NO-mediated transcriptomic and metabolomic investigations have revealed that changes in cellular NO levels via the modification of thiol groups are critical for plants to acclimate against diverse stress conditions, and can be an important product of N metabolism. Recently, some research in NO biology has evidenced that the production of NO is affected by N supply, and free radical NO or exogenous NO donor appears to regulate N assimilation.

This Special Issue focuses on extending current knowledge of nitric oxide signaling in plants, along with the ways NO can interact with other reactive signaling molecules, enzymes and metabolites and also how NO signaling/metabolism can affect plant growth and development under normal or stressed conditions.

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.
