Background

Coarse Cereals include maize, sorghum, oats, barley, foxtail millet, rye, buckwheat, Zizania latifolia, Chenopodium quinoa, Amaranthus hypochondriacus, and legumes. They are rich in dietary fiber, vitamins, minerals (especially trace elements), and some antioxidant phytochemicals such as flavonoids, anthraquinones, polyphenols, vitamins, alkaloids, saponins, polysaccharides and peptides. Certain metabolic components may help fight diseases such as cardiovascular disease, cancer, obesity, and diabetes, depending on the plant. With the rapid deterioration of the global ecological environment, scientists are focusing more attention on the potential coarse crops have in terms of nutrition, medical treatment, and environmental adaptation. Coarse crops may have strong environmental adaptability and abiotic stress resistance in specific areas such as the arid regions of Africa and central Asia, or the mountain ranges of Asia. Compared to main crops and model plants, research on the formation mechanism, development process, and regulation mechanism of environmental adaptability of special metabolic components of coarse grain crops is insufficient.

The main objective of this Research Topic is to systematically illustrate the breakthrough in contributions and the potential of sustainable utilization of coarse grain crops in human health, medical treatment, and diet under the challenges of global climate change. We invite scholars to provide systematic or pioneering insights on the genetic basis of special chemical compositions, nutritional structures, tissue developments, and biological or abiotic adaptability of these coarse grain crops through forward or reverse genetic experiments. We also welcome researchers to analyze the genetic diversity of coarse grain crops in different climatic regions of the world and their relationship with major crops. This can be from the perspective of developmental biology or phylogeny, which will help to understand the process of plant differentiation and evolution. Cutting-edge reviews and original studies on character improvement, as well as variety breeding of coarse grain crops can also inspire cultivation strategies and biotechnology in certain plants planted under stressful environmental conditions.

We welcome submissions of original research, comprehensive or mini-reviews, perspectives, and method papers covering the following topics (but not limited to):
• Systematic and innovative reports on chemical composition and detection methods, frontier dynamic review, and model prediction in quality or characteristic metabolism of cereals.
• The genetic basis, functional gene mining, and systematic molecular mechanism analysis of the formation process of important metabolites.
• Review and strategies of genetic improvement of coarse grain crops.
• Their evolutionary relationship, genetic diversity, and homology with the main crops.
• The interaction process with the environment, including the effects of growth, development, and metabolism of coarse grain crops under biotic/abiotic stress or different treatments, and the relationship between these processes and genetic mechanism.

Keywords: Coarse cereals, Nutritional structures, Chemical composition, Genetic mechanism, Plant developmentm, Diotic / abiotic stress, Evolutionary and genetic diversity

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 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.

  • 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.
