About this Research Topic

Background

Agricultural communities are being affected by climate change. Droughts, heat waves, cold snaps, and flooding are all regarded as severe threats to crop production as they hinder plant growth and development, resulting in yield losses. Plants respond to stress through a complex process that includes changes in physiological and biochemical processes, gene expression, and alterations in the amounts of metabolites and proteins at different developmental stages. This special issue will focus on recent advances in the use of various traditional and modern biotechnological strategies to understand stress adaptation and tolerance mechanisms including (but not limited to) genomics, transcriptomics, metabolomics, proteomics, miRNA, genome editing, transgenic plants, exogenous application of plant growth regulators, and so on.

Abiotic stress is a key constraint to agricultural production around the world. Water deficit, excess precipitation, high and low temperature, and salinity are the most prevalent abiotic stresses. Compaction, mineral availability, and pH-related stressors are among the others. This Research Topic aims to highlight the most recent breakthroughs in plant responses to abiotic stresses and adaptation/tolerance strategies. This special issue provides the advanced toolkit and technologies that are used to investigate and understand plant responses to abiotic stress. The purpose of this special issue is to give a platform for scientists and academics from across the world to promote, share, and discuss new concerns and advancements in the field of abiotic stress in plants.

Current updates and recent developments in the physiological, molecular, and genetic perspectives on combined and sequential stress responses and tolerance in field crops are expected in articles. Original research and review articles dealing with abiotic stress are welcomed. In this special issue, potential topics include, but are not limited to:

• Physiological, biochemical and molecular responses of plants under abiotic stress.
• Systems biology approaches to study abiotic stress in crop plants.
• Phenotyping for abiotic stress tolerance in crops.
• Physiological and molecular characterization of crop tolerance to abiotic stresses.
• Molecular breeding for developing and improving abiotic stress resilience in crops.
• Microbial mitigation of abiotic stress responses in crops
• Omics technologies for abiotic stress tolerance in plants.
• Performance of novel GMO crops under abiotic stress conditions.
• CRISPR-Cas Genome editing tools for the Improvement of abiotic stress tolerance in plants.
• Crop production in abiotic stress conditions.

Keywords: Crop plants, abiotic stress, stress adaptations, tolerance mechanisms, genomics

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.
