About this Research Topic

Background

The symbiotic relationship between arbuscular mycorrhizal fungi (AMF) and plants plays a vital role in enhancing nutrient uptake and overall plant health. Recent research has shed light on the intricate interactions within this symbiosis, particularly the involvement of mycorrhizal helper bacteria (MHB) as facilitators influencing the establishment and functioning of AMF associations. The synergistic interplay between MHB and AMF constitutes a dynamic and complex process that affects nutrient cycling and plant fitness. Understanding the molecular mechanisms controlling these interactions is essential for the fine-tuning of agricultural practices and the advancement of sustainable crop production. Additionally, MHB can be used in phytoremediation applications, thus reducing stress, and aiding beneficial outcomes.

This Research Topic aims to delve into the complex dynamics of MHB and their interactions within the AMF symbiosis. The primary goal is to address existing gaps in our understanding of these interactions and elucidate their implications for enhancing plant-microbe associations based on experimental data obtained and published in recent years. Recent advancements in molecular biology, genomics, and ecological studies have paved the way for a more comprehensive exploration of the roles played by MHB in facilitating and modulating AMF symbiosis. By revealing the underlying mechanisms governing these interactions, this Research Topic aims to offer useful information for optimizing agricultural practices for sustainable crop production.

Our research goal includes investigating key questions such as the identity of the bacterial species involved, the specificity of plant-microbe interactions, the molecular signaling pathways employed, and the ecological consequences of their interactions within the AMF symbiosis. By addressing these questions, we aim to provide valuable insights for fully harnessing the potential of MHB in promoting plant health and nutrient acquisition. Ultimately, this research endeavors to bridge the knowledge gaps in the field by providing the groundwork for more informed and effective strategies to augment plant-microbe interactions in agroecosystems.

The Research Topic explores the multifaceted interactions between MHB and AMF symbiosis, delving into their molecular complexities, ecological implications, and potential applications in agriculture and phytoremediation. We encourage researchers to submit articles pertaining to, but not limited to, the following topics:

- Implications of tripartite symbiosis for plant physiology and efficiency in mycorrhization

- Molecular mechanisms underlying the interaction between MHB, AMF, and plants

- Genome mining of MHB

- Application of MHB in phytoremediation

- MHB's contributions to biotic/abiotic stress alleviation in plants

- Application of MHB in agricultural practices

This Research Topic welcomes submissions of Original Research and Reviews.

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.

• Can I suggest a new Research Topic? 

  Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

• 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. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

• As a junior researcher, can I be involved in editing a Research Topic? 

  If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.
