About this Research Topic

Background

Revealing the genetic mechanism of the growth, development and reproduction of cultured animals will provide a theoretical basis for the domestication of wild germplasm and the development of new breeds. The molecular basis of important economic traits will also provide a theoretical basis for cultivating new varieties of high-yield or stress-resistant breeding animals.

The research on germplasm resources mining of aquatic animals has made great progress in recent years, especially in the mining of functional genes and regulatory networks related to traits. More and more varieties and economic traits have received more extensive attention. At the same time, the mature commercialization of high-throughput sequencing technology provides strong support for the mining of functional genes and regulatory sites associated with traits. With the help of omics technology, it is efficient to reveal the coordination mechanism of key regulatory molecules in the process of aquatic animals' development, growth, sexual maturity, neuroendocrine and nutritional metabolism. It is helpful to reveal the signal pathways closely related to disease resistance and stress resistance. It is also conducive to the research on the epigenetic molecular basis of environmental regulation affecting the phenotype of traits.

In view of insufficient development and utilization of aquatic animal resources, the biological basis of environmental adaptation and the basic laws of reproductive development of aquatic animals deserve attention and exploration. At the same time, the research on genetic laws and molecular mechanisms in the growth, development, reproduction and other aspects of economic species should also be strengthened, focusing on screening and mining functional genes, regulatory sites and regulatory networks related to breeding traits.

The Research Topic is on studies using omics technology, particularly the multi-omics method, to explore genetic resources related to the economic traits of aquatic animals. It calls for original review and research papers related to the development and utilization of genetic resources of aquatic animals in any of the following research topics:

1、 Key gene regulatory networks and molecular mechanisms of sex, reproduction, growth, development, body color, neuroendocrine and stress-resistance related traits in aquatic animals
2、 The role and impact of epigenetics on traits responding to environmental changes in aquatic animals
3、 Evaluation of germplasm resources and analysis of genetic architecture targeting traits in aquatic animals
4、 Utilization of genomic resources and improvement of traits under artificial intervention

Keywords: gene regulatory networks; molecular mechanisms; epigenetics; genetic architecture; multiomics; aquatic animals

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

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 it falls 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.

• Who leads a Research Topic? 

  A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

  The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

• What is the role of a topic editor?

  As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

   

  You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters.
