Advancing Neglected-Underutilized Crop Species (NUCs): Integrated Approaches, and Development of Tools for improving NUCS

About this Research Topic

Background

About 20 plant species provides the vast majority - up to 90% - of our food. At a global scale, the reliance on this limited number of “major” crops, coupled with decreasing genetic variation within each of them, is more and more being recognized as a risk to food security, environment, and our own health. This becomes clearer whenever a main production area for a particular major crop is affected. One way to mitigate this risk is to look at species that have been replaced by major crops but were once well fitted within each different agricultural system.

Many terms have been used to define them: “neglected”, “underutilized”, “orphan”, “minor”, and “future” crops; for simplicity, we will refer to them as NUCS (Neglected-Underutilized Crop Species). They vary across taxonomy and uses, stretching across legumes, cereals, fruits, vegetables, leafy green, algae, mushrooms, and tubers. What they have in common is that they have been left behind by mainstream research and policies, despite their traditional place in human nutrition (and society), and their potential for making agriculture more resilient and sustainable.

While there is increasing contribution towards characterizing the potential of a few NUCS, leading them out of marginalization and placing them within improvement programs, there is still a need for more studies taking an integrated, multi-omics approach to dissect traits linked to stress resistance, or nutritional value. For many others, research has yet - or has just started - to pick up, and they still required basic tools for bringing them into more advanced studies.

Submissions to this Research Topic should be related to NUCS. In line with scope of the journal, studies advancing our understanding of the plant biology of NUCS will be considered, but we encourage the submission of manuscripts focusing on:

1) Studies on resilience traits (e.g., stress tolerance), adaptation (e.g., photo-thermal effect), and nutritional value. Particularly of interest will be comparative studies in which NUCS are assessed alongside major, better-studied crops and varieties.

These should include an integrated approach (multi-omics), using a combination between different areas such as: genetics, physiology, phenomics, metabolomics, ionomics, and/or bioinformatics.

2) Generation of tools for the advancement of research on NUCS that still lack these. For example:
- the generation of mapping populations, or characterization of a panel of common accessions for phenotypic and genetic studies.
- development of molecular markers.
- transcriptome databases.

3) Studies on applications of high-throughput phenotyping approaches, particularly for the optimization and inclusion of these approaches on NUCS.

4) NUCS studies using translational research approaches, transferring knowledge and resources from one species to another.

Please note: Frontiers in Plant Science does not accept solely descriptive studies - studies which report responses to treatments and descriptive reports of ‘Omics studies will not be considered if they do not progress biological understanding of these responses.

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.
