Abiotic Challenges and Symbiotic Dynamics in Agricultural Ecosystems

About this Research Topic

Background

Abiotic stress factors such as drought, salinity, extreme temperatures, heavy metal toxicity, and nutrient deficiencies significantly impact plant growth and development. These environmental stresses disrupt the symbiotic relationships that plants form with microbes, particularly mutualistic ones like nitrogen-fixing rhizobia. Under normal conditions, these beneficial microbes enter the plant roots and form nodules, which provide critical nutrients that enhance plant growth and resilience. However, under abiotic stress, this crucial symbiotic process is compromised by alterations in microbial entry pathways, root morphology, soil structure, and the overall chemical environment of the rhizosphere. This can lead to less efficient nutrient acquisition, reduced crop productivity, and thus pose significant challenges to sustainable agriculture by affecting soil health and the equilibrium of the ecosystem.

This Research Topic aims to delve into the complex dynamics between abiotic stress and plant-microbe symbiotic relationships. Emphasizing the molecular and chemical shifts that occur during such stress, this research will investigate how these changes undermine the symbiotic efficiency, thus affecting nutrient transfer and plant health. By understanding the interactions at this intricate biological interface under various stress conditions, the goal is to forge advancements that could lead to the development of stress-resilient plant varieties and innovative agricultural practices that enhance crop productivity and sustainability in the face of escalating climate challenges.

To effectively map the scope of how environmental challenges influence the establishment and efficacy of mutualistic symbioses, we invite research that may include, but is not limited to, the following areas:

• Dynamics of microbial entry mechanisms under varying abiotic stresses and their influence on nodulation processes

• Adaptations in root architecture and rhizosphere modifications under stress-induced scenarios affecting microbial colonization

• Advances in microbial engineering to boost resilience to abiotic stress, focusing on enhanced microbial motility and symbiotic efficiency

• Detailed analysis of root exudates and chemical signaling changes due to stress and their impact on microbial attraction and colonization

• Examination of plant defense responses and their influence on the success or disruption of nodulation under stress conditions

• Application of omics technologies to uncover intricate details of plant-microbe interactions under stress

• Discussions on implementing research findings into practical agricultural strategies to improve crop resilience and sustainability in stress-prone environments

Submissions of various article types, including Original Research Articles, Review Articles, Methodological Papers, and Case Studies, are highly encouraged. This comprehensive exploration will not only enrich our understanding of abiotic stress impacts on symbiotic interactions but will also provide critical insights for enhancing agricultural practices and food security in a changing climate.

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.
