Unraveling Sugar Signaling: Insights into Plant Stress Responses

Dear Colleagues,

Plants have evolved intricate sugar signaling networks to coordinate sugar status with stress responses. Certain sugars, such as glucose, fructose, trehalose, and sucrose, act not only as metabolites but also as plant signaling molecules. Unraveling sugar signaling pathways is of great interest to the scientific community to better understand the integration of environmental stress responses in crops.

While great progress has been made to unravel sugar signaling pathways, many questions remain. Glucose signaling in plants is similar to pathways in yeast and mammals and thus has long been accepted, while sucrose signaling, though suggested decades ago, is only slowly gaining acceptance.

We welcome original research articles, reviews, and perspectives that address the following topics:

• Sugar sensing and signal transduction pathways in response to stress;
• Sugar signaling at the crossroads of responses to biotic and abiotic stresses;
• Crosstalk of sugar signaling and other signaling pathways;
• The dual role of sugars as metabolites and signals.

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.
