Background

Aluminum (Al) toxicity in acidic soils significantly restricts plant growth and agricultural productivity, especially in regions characterized by highly weathered, infertile, and acidic soils, including tropical and subtropical areas such as Latin America, Sub-Saharan Africa, Southeast Asia, and parts of Australia. Crops frequently cultivated in these regions, notably rice, maize, soybean, wheat, lentil, barley and banana, exhibit varying levels of susceptibility to Al stress. With climate changes and intensifying agricultural practices projected to increase soil acidification, Al toxicity is expected to become more widespread, presenting escalating threats to global food security. At the physiological level, plant roots are particularly impacted as Al ions interfere with cellular structures and functions, reducing root elongation and impairing essential physiological processes. Although plants have evolved several strategies to respond, such as releasing organic acids into the rhizosphere and sequestering Al ions in vacuoles, our comprehension of these mechanisms, particularly their genetic and molecular regulations, remains incomplete. Recent research has identified several crucial genes and pathways involved—including STOP1 (Sensitive To Proton Rhizotoxicity 1) and the ALMT (Aluminum-Activated Malate Transporter) gene family—but critical gaps remain regarding how these pathways are transcriptionally controlled and can be enhanced in crop varieties.

This Research Topic aims to enhance understanding of the mechanisms underpinning Al tolerance and develop innovative approaches for improving plant resilience, focusing specifically where Al stress is prevalent and persistent. The primary objectives include characterizing the roles and transcriptional regulation of specific genes (such as STOP1 and ALMT gene families), exploring novel mechanisms involving polyamines, miRNAs, and DNA Damage Response (DDR) pathways, and investigating physiological and molecular aspects of Al tolerance specifically within economically relevant crops to promote enhanced tolerance. Furthermore, the research will evaluate strategies for confronting Al stress through both genetic improvement and sustainable agricultural practices, including amendments with substances such as gypsum and boron, or beneficial microorganisms.

To gather further insights into Al tolerance mechanisms and their application for improved crop resilience—particularly relevant to regions and crop systems experiencing significant and increasing Al toxicity—we welcome articles addressing, but not limited to, the following themes:

• Identification and characterization of key genes, molecular pathways, and transcriptional regulation mechanisms involved in Al tolerance

• Novel approaches to Al tolerance involving polyamines, miRNAs, or DNA Damage Response (DDR) pathways

• Insights into physiological and molecular responses of economically important crops (e.g., rice, maize, soybean, wheat, lentil, barley, banana) to Al stress

• Strategies to enhance Al-tolerance through amendments such as gypsum, boron, and other soil improvement measures

• Beneficial microbial interactions, including fungi and other microorganisms, to mitigate Al toxicity in acidic soils

• CRISPR/Cas-based gene editing methods to improve Al tolerance traits in plants

• Screening, breeding, and phenotyping approaches for selecting germplasm with enhanced Al tolerance

Topic editors

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.
