About this Research Topic

Background

Modern agriculture requires scientific and technological innovations to tackle issues regarding the quantity and quality of plant products for the benefit of farmers, consumers, and the environment. New methods to improve plant resistance to pest and disease, crop quality, and yield are required to overcome the challenges of having enough and safe food, feeding, and producing sustainable biomass under the current context of climate change.

RNA silencing is a sequence-specific mechanism of regulation of gene expression based on the action of micro- and small RNA molecules (miRNA and siRNA) derived from double-stranded RNA (dsRNA) precursors. These small RNAs can trigger post-transcriptional gene silencing (PTGS) since they guide the sequence-specific cleavage of a target RNA. These strategies represent useful tools for functional genomics and crop biotechnology. Interfering RNAs can be used to improve plant growth and productivity by suppressing undesirable traits, thus switching resources to more beneficial traits as quality and yield. Using a ‘host-induced’ silencing approach (HIGS), interfering RNAs can be used to regulate gene expression in pests, disease-causing organisms, and parasitic plants. Additionally, spray induced gene silencing (SIGS) is a more recent strategy for bio-based crop protection. Recent studies demonstrate that spraying dsRNAs and sRNAs that target essential pathogen genes on plant surfaces may confer efficient crop protection. This strategy of disease control is potentially sustainable and more environmentally friendly than traditional chemical solutions.

This Research Topic aims to promote the discoveries of new mechanisms and players implicated in the regulation of gene expression mediated by RNA interference, as well as, the translational application of RNA-based silencing to modulate plant metabolism and adaptation to biotic and abiotic constraints. This Research Topic arises from the activities of the European COST Action CA15223 iPLANTA-Modifying plants to produce interfering RNA.

We welcome excellent Original Research and Review articles coming from both iPLANTA participants and non-iPLANTA participants dealing with various aspects of RNA interference in plants. Manuscripts should address, but not be restricted to, the following topics:

- New findings on the fundamental knowledge on target specificity, activity, and regulation of siRNA and miRNA – mediated silencing mechanisms in plants.
- Evaluation of the efficacy of RNA molecules for plant protection against diseases and pests either using HIGS or SIGS.
- Evaluation of the efficacy of RNA molecules to trigger metabolic changes in plants.
- Examination of the specificity of the selected miRNAs, siRNAs, and dsRNAs and their effects on both target and non-target/off-target organisms.
- Understanding the modes of transmission, uptake, systemic spread, and degradation of miRNAs, siRNAs, and dsRNAs in target and non-target organisms.
- Compare efficiency, risk, and benefits of RNAi against available technologies.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
