The Signalling Function of Plant GTP-Binding Proteins

Dear Colleagues, 

GTP-binding proteins are central in various processes determining plant shape and function, including environmental adaptation. These versatile signalling molecules can interact with the plethora of upstream regulators and downstream effectors. In this way, they are capable of integrating various hormonal, developmental and abiotic/biotic stress signalling pathways. At the cellular level, they control the size, shape and polarity of cells organising primarily the cytoskeleton, vesicular transport, and gene expression. Despite the accumulating experimental data signifying the role of GTPases and their interacting proteins in plant development and adaptation, our knowledge about the associated signalling pathways is still scarce. The number of GTPase-mediated signalling pathways that have been fully mapped from a specific receptor to a specific final target is rather low.

With this Special Issue, we would like to encourage the publication of further details about the signalling function of plant G-proteins. Manuscripts characterising the G-proteins themselves, as well as their regulators, effectors and further upstream and downstream events linking these molecules to developmental, hormonal, and environmental responses, are 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. 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.
