About this Research Topic

Background

The concept of the holobiont has been proposed for plants. The term ‘holobiont’ was first defined by Lynn Margulis in 1991, as a simple biological unit involving a host and a single inherited symbiont. Zilberg-Rosenberg and Rosenberg (2008) expanded this definition to the entire microbiota. These authors have further proposed the holobiont to be a selection unit, which underlies the hologenome based theory of evolution.

This Research Topic is one of two volumes on the Plant Holobiont:
Volume I: Microbiota as part of the holobiont; challenges for agriculture
Volume II: Impacts of the Rhizosphere on Plant Health

Plants live in close association with the microbes that inhabit the rhizosphere, and the presence of this complex plant-associated microbial community is important for plant health. In nature, plants are continuously exposed to a variety of environmental factors that influence both the above- and below-ground structures. In particular, the composition of the root microbiome may be altered by specific biotic and/or abiotic stressors and, subsequently, has consequences on the reconfiguration of the microbiome, which may aid the plant in reacting, and in some cases overcoming, the adverse constraints. Re-modulation of the rhizosphere microbiome composition is often accompanied by active root excretion of selective compounds that can be antagonistic/unfavorable and/or proliferative to microbes. It is of great interest to understand the signaling molecules produced by plants when faced by abiotic and biotic stressors, and to determine how these compounds can be responsible for the recruitment of “helper” microbes in the rhizosphere that aid the plant defense response.

At the same time, the interaction between the plant and its root microbiome can affect plant defense responses and subsequently influence crop productivity and quality. Some root symbiotic microbes may establish positive interactions with plants either by attracting other beneficial microbes or insects, directly or indirectly or by increasing plant tolerance to specific stresses.

This Research Topic aims to present investigations on plant-microbe interactions occurring in the rhizosphere when plants are subject to biotic or abiotic stress conditions. This will examine the molecular dialogue that occurs not only between the root microbiome and its host plant but also among the components/members of the related microbiota, with special interest on those associations that elicit plant beneficial effects.
This Research Topic will consider the submission of Reviews, Technology Report, Methods, Opinion, and Original Research Articles highlighting the following aspects:

· Recognition of basic signaling compounds, including nutrients, that are responsible for maintaining a healthy exo- and/or endophytic microbial community with the plant root system;
· Identification of “help signals” released in the rhizosphere by the stressed plants that aid in the recruitment or “activation” of beneficial microbes to the victim;
· Determine the effects of root colonization by microbes that can systemically influence plant defenses to above-ground stresses;
· Modulation of the plant rhizosphere microbiome in response to both biotic and abiotic factors.

Keywords: Rhizosphere microbiome, Biotic/abiotic stress, Beneficial microbes, Root exudates, Plant-microbe interaction

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.
