About this Research Topic

Background

Plant-microbe interactions in the rhizosphere are pivotal for plant health, growth, and nutrient uptake, playing a key role in ecological and agricultural systems. Researchers have long recognized that beneficial microbes can enhance plant growth, improve resistance to pathogens, and contribute to soil health.

Concurrently, phytoremediation, (the use of plants to remove, transfer, or stabilize contaminants in soil and water), has emerged as a sustainable strategy for environmental cleanup. Understanding the precise mechanisms underpinning these processes requires sophisticated analytical tools.

Stable isotope techniques, particularly those involving isotopic labeling and tracing, have revolutionized our ability to study complex biological systems. By using isotopes to label specific atoms in metabolic pathways, scientists can monitor how carbon and nutrients flow through plants and their associated microbial communities. This research can lead to optimized strategies for enhancing crop productivity, soil health, and effective phytoremediation practices, addressing critical environmental and agricultural challenges.

Phytoremediation faces challenges due to the complex interactions between plants, soil, and microbial communities, which are not fully understood. Traditional methods fall short in elucidating how nutrients and contaminants are metabolized and transported in these systems. To enhance phytoremediation efficiency, a deeper understanding of these processes is needed.

Isotope Contribution and Recent Advances:

Stable isotopes, such as ^13C and ^15N, offer powerful tools for tracing the pathways of elements through ecological systems. Labeling contaminants or nutrients with isotopes allows researchers to track their movement and transformation using advanced techniques like isotope ratio mass spectrometry (IRMS) and compound-specific isotope analysis (CSIA).

To address this, the research will employ stable isotope tracing to map the uptake and distribution of heavy metals (e.g., ^65Zn, ^63Cu) and isotope-labeled organic pollutants within plants and microbes. Coupling these with metagenomics and transcriptomics will reveal how specific microbial communities contribute to contaminant breakdown and nutrient cycling.

This approach aims to identify key genes in phytoremediation, enabling the development of genetically engineered plants and tailored microbial consortia for enhanced efficiency. By integrating isotope tracing and molecular biology, this research could significantly advance our understanding of plant-microbe interactions, leading to more effective and sustainable phytoremediation strategies.

This Research Topic aims to advance phytoremediation using stable isotope tracing and molecular biology. We seek contributors to submit manuscripts addressing the following themes:

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.
