About this Research Topic

Background

The field of plant microbiomes and microbial formulations is gaining significant attention as a sustainable alternative to traditional agrochemicals, which have been shown to negatively impact the environment and human health. Beneficial microorganisms offer a promising solution to enhance crop production through eco-friendly technologies. Despite the potential, there remains a substantial gap in the knowledge required to effectively utilize bacterial formulations to protect plants from pathogens and promote growth. Recent studies have focused on developing microbial formulations that leverage both direct mechanisms, such as nitrogen fixation and phytohormone production, and indirect mechanisms, like the inhibition of phytopathogens through secondary metabolites. However, translating these laboratory successes to field applications has proven challenging, often due to the lack of adaptation of microbial strains to specific environmental conditions. The burgeoning understanding of plant microbiomes, particularly those associated with the rhizosphere and internal plant tissues, has yet to be fully harnessed for agricultural applications. Unlike the gut microbiome, where fecal transplantation has shown success, the scale and complexity of crop production present unique challenges that necessitate a deeper understanding of plant-associated microorganisms.

This research topic aims to bridge the gap between laboratory research and field application by advancing our understanding of plant microbiomes and developing effective microbial formulations. The primary objectives include isolating and characterizing novel microorganisms, elucidating the microbial mechanisms that promote plant growth, and designing multispecies microbial formulations that are resilient to various environmental stresses. Specific questions to be addressed include: What are the key microbial species involved in plant growth promotion? How do these microorganisms interact with each other and with the plant host? Can we develop microbial formulations that are effective under diverse field conditions?

To gather further insights into the boundaries of this research, we welcome articles addressing, but not limited to, the following themes:

- Isolation and characterization of new microorganisms detected in plant microbiomes.
- Study of microbial mechanisms involved in plant growth, especially when microorganisms interact with other microorganisms and the plant.
- Design of mixed microbial formulations based on microbiomes reported to promote the growth of plants under laboratory, greenhouse, or field conditions.
- Effects of the application of beneficial microorganisms on the plant microbiome.
- Analysis of patents related to the capacity to promote the growth of plants and its relationship with plant microbiomes.

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?
