About this Research Topic

Background

Microorganisms in nature engage in intricate interactions with a diverse array of co-existing organisms including other microorganisms across different taxa and higher eukaryotic organisms. These interactions encompass various dynamics such as competition, predation, cooperation, antagonism, parasitism, symbiosis, and pathogenesis. Despite the richness of these interactions, much of our understanding of microorganisms stems from studies conducted on pure-cultured populations, limiting our insight into their interactions with neighboring organisms of different taxa. Especially, research on intercellular communication of microorganisms has focused on the signaling systems within microbial species using pure-cultured population, neglecting the influence of other living organisms in the same niche. For getting deeper insights into microbial behaviors, particularly in the contexts of pathogenesis, symbiosis, and ecosystem dynamics, it is crucial to understand how microbial organisms communicate and interact with other organisms.

This Research Topic aims to advance our understanding of microbial communication mechanisms underlying interspecific interactions in natural conditions, particularly in the contexts of (but not limited to) pathogenesis, symbiosis, or ecosystem dynamics, by introducing most updated and innovative research activities. Expanding our understanding of microbial intercellular communications to and beyond interspecific levels is essential for elucidating the behaviors of microorganisms in nature more accurately for their diverse ecological functions. Through this Research Topic, we also seek to deeper insights into various outcomes of interspecific microbial interactions such as competition, antagonism, cooperation, and predation. These endeavors will contribute to a broader understanding of microbial biology in various ecosystems.

The scope of this Research Topic would include (but not be limited to) interspecific microbial interactions focusing on intercellular communications via signal molecules between microorganisms in different taxa or inter-kingdom interactions between microorganisms and eukaryotic hosts in pathogenic or symbiotic relations.

We invite Original Research, Review, and Perspective articles covering this Research Topic. The sub-areas in this Topic include but are not limited to:
- Cell biology studies demonstrating microbial behaviors in various types of relation to adjacent microorganisms or host cells.
- Multi-omics studies for a holistic view of cellular changes upon various interspecific interactions.
- Molecular genetics studies to identify genes crucial for interspecific communications and understanding their mechanisms.
- Biochemistry and molecular biology studies to elucidate the signaling mechanisms for interspecific communications.
- Beneficial or adverse effects of antibiotics or other chemicals on interspecific interactions of target microorganisms.

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.
