About this Research Topic

Background

Associations between living organisms can improve the fitness of one or more of the partners. Well-known examples include lichens and diverse interspecific plant facilitations. The participating organisms thrive well in their natural environments when associated, but seem to be hampered when they are isolated. Those interactions might be particularly valuable in harsh environments where resources are limited and physical conditions are severe.

Arid and semi-arid lands cover a great portion of the earth surface from the poles to the equatorial regions and include highly populated areas by humans. Temperature fluctuations, low availability of water and high solar radiation are some of the critical variables that hinder life in these areas, where resource islands, biological soil crusts (BSC) and barren soils prevail. Vegetation can be conspicuous in the first ones, but BSC usually contain non-vascular or small-sized vascular plants and even barren soils are colonized by plants in some periods of time. For growing in those sites, particularly in their vulnerably juvenile phase, the plants depend on other organisms and on physical barriers that create micro-environmental conditions that either accumulate resources or abate the severity of physical conditions. Plants adapted to arid and semi-arid lands possess inherent traits for their survival in those environments. Nevertheless, they also depend on microorganisms to succeed.

With a growing and urgent demand for sustainable agriculture in semi-arid and arid regions, and with the challenges agriculture faces with the increasing effects of climate change, a growing number of researchers are studying facets of the biological traits of the plant-microorganism interactions both in wild and domesticated plants. Current knowledge on the intimacy of the plant-bacteria interactions in desert soil is still scarce, as well as the roles that bacteria, archaea, microbial eukarya and viruses play in terrestrial ecosystems, but it is growing with the increased interest by the scientific community for their biology, including physiology, biochemistry, genetics, omics, biogeography, biogeology, molecular biology, ecology, and evolution among others.

This Research Topic aims to gather knowledge on the interaction between bacteria and archaea with plants growing in arid and semi-arid lands, both in wild and cultivated plants. Fundamental and applied research papers as well as review articles are welcome, including but not limited to:

- Diversity of plant-associated bacteria and archaea.
- Molecular interactions between plants and associated bacteria and archaea.
- Inoculation of crops and endangered plants.
- Geographical distribution of plant-associated microorganisms.
- Localization of microorganisms at the cellular level.
- Co-evolution of microorganisms and plants.
- Role of bacteria and archaea in land reclamation.
- Studies on rhizosphere and endosphere microbiome
- Studies of physiological, proteomic and metabolomic aspects of terrestrial bacteria and Archaea associated to plants and their communities

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.

• Who leads a Research Topic? 

  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.

• What is the role of a topic editor?

  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.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).
