Special Issue Information

Dear Colleagues,

This Special Issue of Plants (MDPI) collects Selected Papers from the 2nd International Electronic Conference on Plant Science. The SI is focused on deepening plant research at all levels, from the molecular through to the whole plant and community scale, also including bioinformatics and modeling approaches. Contributions will also cover new topics, such as plant–plant communication, protection of plant biodiversity, and plants in urban environments.

Equality and inclusion principles will be respected, as well as access to the wider and more diverse scientific community. We encourage submissions from scientists at all career stages and from all backgrounds and aim for an equal gender balance.

We look forward to receiving your contributions to this Special Issue and would like to thank you in advance for your active support.

Sincerely,

Prof. Dr. Adriano Sofo
Prof. Dr. Dimitris L. Bouranis
Dr. Suresh Awale
Dr. Giorgio Perrella
Dr. Fabrizio Araniti
Dr. Giedrė Samuolienė
Guest Editors

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.

Keywords

  • plant physiology, signaling, and communication
  • plant ecology, biodiversity, and developmental biology
  • plant response to stresses and changing environment
  • phytochemistry and phytoremediation, plants in urban ecosystems
  • plant nutrition and plant–soil–microorganism interactions

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Plants are a promising platform for recombinant protein production. Here we propose a novel approach to increase the level of viral vector-mediated recombinant protein synthesis. This approach is based on the hypothesis that antiviral protection is weakened during the antibacterial cellular response. We suggested that introduced to the cell foreign nuclear localized proteins, including effectors such as bacterial nucleomodulins, can interfere with the import of cellular nuclear proteins and launch antibacterial defense reactions, creating favorable conditions for cytoplasmic virus reproduction. Here, we performed synthesis of an artificial nuclear protein—red fluorescent protein (mRFP) fused with a nuclear localization sequence (NLS)—in plant cells as a mimetic of a bacterial effector. Superproduction of mRFP:NLS induced Nicotiana benthamiana γ-thionin (NbγThio) mRNA accumulation. Both NLS-containing protein synthesis and increased NbγThio expression stimulated reproduction of the viral vector based on the genome of crucifer-infecting tobacco mosaic virus (crTMV) in N. benthamiana leaves. We isolated the NbγThio gene promoter (PrγThio) and showed that PrγThio activity sharply increased in response to massive synthesis of GFP fused with NLS. We conclude that NLS-induced PrγThio activation and increased accumulation of Nbγthio mRNA led to the stimulation of GFP expression from crTMV: GFP vector in the transient expression system.
