Special Issue Information

Dear Colleagues, 

Alternative splicing (AS) is widespread in humans and plants. Recent evidence suggests that the process of splicing is largely co-transcriptional, and introns are spliced when pre-mRNA is still attached to DNA by RNA polymerase II (RNAPII). Since DNA is packaged into chromatin, it provides a natural barrier to the advancing RNAPII and influences the splicing process. Exons are usually GC-rich (nucleosome-rich compared to GC-poor introns), and transcription through nucleosome-rich regions with compact chromatin tends to be slower. Nucleosome occupancy is also lower in alternatively spliced exons compared to those that are constitutively spliced. DNA methylation affects exon recognition and is influenced by the GC architecture of exons and flanking introns in humans. Recent evidence suggests that histone modifications also directly affect AS in humans. Such evidence in plants is lacking; however, similar mechanisms may be involved, as the majority of Arabidopsis genes exhibit similar gene body methylation to other organisms. Not surprisingly, novel findings in plants have shown that the process of splicing is indeed predominantly co-transcriptional in plants; however, the mechanistic details remain to be elucidated. Therefore, this Special Issue aims to address how differences in DNA methylation, chromatin architecture, histone modification and RNA modifications influence splicing.

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. 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.

Plants use complex gene regulatory mechanisms to overcome diverse environmental challenges. For instance, cold stress induces rapid and massive transcriptome changes via alternative splicing (AS) to confer cold tolerance in plants. In mammals, mounting evidence suggests chromatin structure can regulate co-transcriptional AS. Recent evidence also supports co-transcriptional regulation of AS in plants, but how dynamic changes in DNA methylation and the chromatin structure influence the AS process upon cold stress remains poorly understood. In this study, we used the DNA methylation inhibitor 5-Aza-2′-Deoxycytidine (5-aza-dC) to investigate the role of stochastic variations in DNA methylation and nucleosome occupancy in modulating cold-induced AS, in Arabidopsis thaliana (Arabidopsis). Our results demonstrate that 5-aza-dC derived stochastic hypomethylation modulates nucleosome occupancy and AS profiles of genes implicated in RNA metabolism, plant hormone signal transduction, and of cold-related genes in response to cold stress. We also demonstrate that cold-induced remodelling of DNA methylation regulates genes involved in amino acid metabolism. Collectively, we demonstrate that sudden changes in DNA methylation via drug treatment can influence nucleosome occupancy levels and modulate AS in a temperature-dependent manner to regulate plant metabolism and physiological stress adaptation.
