Special Issue Information

Dear Colleagues,

Reacting to environmental stimuli with the appropriate molecular and genetic responses is essential to all life forms and even more so in sessile and immobile organisms like plants. Higher eukaryotes, including plants, use both rapid early mechanisms such as the activation of channels and kinases, directly or indirectly through protein sensors, as well as the slower systemic adaptive responses that include changes in their transcriptomes and proteomes. To enable these processes and concomitantly tune their responses to the environment, complex cellular signaling mechanisms have evolved, many of which are somewhat different from their animal counterparts. Recent decades have seen a rapid expansion of our understanding of these processes, mainly thanks to the availability of many complete genomes and the subsequent development of “omics” technologies as well as steadily improving imaging technologies.

With this Special Issue entitled “New Horizons in Plant Signaling”, we aim to broaden our understanding of novel signaling molecules and signaling mechanisms. In addition, we also invite reports on novel technologies, including computational methods to study cellular signaling in planta. The molecules under consideration include but are not limited to peptidic hormones, steroids, nucleotides, Ca2+, nitric oxide (NO), and lipids.

We will consider different formats, including short reviews, opinion articles, hypotheses and reports of novel exciting findings—even if only preliminary evidence is presented. The submissions will typically entail findings from model organisms but will not be restricted to them.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.

Protein phosphatase 2A (PP2A) is a strongly conserved and major protein phosphatase in all eukaryotes. The canonical PP2A complex consists of a catalytic (C), scaffolding (A), and regulatory (B) subunit. Plants have three groups of evolutionary distinct B subunits: B55, B’ (B56), and B’’. Here, the Arabidopsis B’ group is reviewed and compared with other eukaryotes. Members of the B’α/B’β clade are especially important for chromatid cohesion, and dephosphorylation of transcription factors that mediate brassinosteroid (BR) signaling in the nucleus. Other B’ subunits interact with proteins at the cell membrane to dampen BR signaling or harness immune responses. The transition from vegetative to reproductive phase is influenced differentially by distinct B’ subunits; B’α and B’β being of little importance, whereas others (B’γ, B’ζ, B’η, B’θ, B’κ) promote transition to flowering. Interestingly, the latter B’ subunits have three motifs in a conserved manner, i.e., two docking sites for protein phosphatase 1 (PP1), and a POLO consensus phosphorylation site between these motifs. This supports the view that a conserved PP1-PP2A dephosphorelay is important in a variety of signaling contexts throughout eukaryotes. A profound understanding of these regulators may help in designing future crops and understand environmental issues. Full article
