About this Research Topic

Background

From soil to elusive invaders, entomopathogenic fungi are globally distributed multifunctional lifestyle microorganisms able to transition between different natural environments. Thriving as saprophytes in the soil, establishing endophytic relationships with plants, and operating as discreet parasites within arthropods, entomopathogenic fungi illustrate their remarkable adaptability and ecological relevance. Recent advances in molecular biology and genomic techniques have provided unprecedented insights into the genetic basis of host specificity and evolution dynamics. This Research Topic aims to explore the intricate interactions between entomopathogenic fungi and their diverse range of hosts exploring the multifaceted relationships between them. Furthermore, we seek to contribute significant new insights about the biodiversity of pathogenic fungi and the importance of these fungi as natural regulators of populations of insects. Additionally, we intend to explore potential applications of this knowledge in fields ranging from integrated pest management to sustainable agriculture, considering the delicate balance between natural equilibrium and human intervention as a biocontrol strategy for economically and medically significant pests.

Concerns regarding pest management and the limitations of chemical insecticides for controlling pests of agronomical and medical significance have led to intensive research into alternative, sustainable approaches. Over the past two centuries, entomopathogenic fungi have emerged as a focal point in this scenario. Their genetic, physiological, and ecological flexibility enables them to transition between life cycles, alternating between pathogenic associations with arthropods and mutually beneficial associations with other hosts. Entomopathogenic fungi have developed intricate strategies to overcome insect immune defenses, while insect hosts employ a combination of behavioral avoidance, physical barriers, and innate immune defenses in a captivating co-evolutionary 'arms race'. In the case of plants, entomopathogenic fungi can establish rhizosphere colonization and beneficial root and plant endophytic associations. These interactions typically promote plant growth and enhance stress and pest resistance, creating a mutually beneficial environment that supports the long-term persistence of entomopathogenic fungi, thereby initiating subsequent infection cycles.

This Research Topic aims to build upon this foundation and invite contributions to delve into the multifaceted relationships between fungi and hosts. Topics of interest include mechanisms of host-pathogen interactions, coevolutionary dynamics, as well as the ecological implications for both hosts and fungi. Additionally, we encourage investigations into the potential applications of this knowledge in sustainable pest management approaches. Original research articles, reviews, and methodological papers are welcomed to provide fresh insights into this dynamic interplay.

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 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.

• 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?
