Exploring Cold Tolerance and Stress in Plants

About this Research Topic

Background

Cold tolerance in plants is a vital focus within the field of plant abiotic stress research, as extremely low temperatures severely restrict the development of plants. As climate variability becomes more pronounced, understanding plant responses to cold stress is essential for agricultural resilience and ensuring food security. Cold stress can detrimentally affect plant growth and yield, leading to significant agricultural losses. The complexity of physiological and molecular plant responses to cold conditions necessitates continued exploration to uncover critical mechanisms that enable or enhance cold resilience, including the role of reactive oxygen species (ROS) and antioxidants. Moreover, cold stress interferes with the reproductive biology of plants, leading to pollen and ovule sterility, directly contributing to yield losses.

Recent research has highlighted adaptive plant responses to cold, such as identifying key genes responsible for cold tolerance, the production of cryoprotective substances, and alterations in cellular pathways. Innovations in understanding have brought to light receptor-like kinases (RLKs), which are believed to play a pivotal role in signaling the plant’s response to cold, alongside hormonal stress responses. Epigenetic regulation, including DNA and RNA methylation, has emerged as a significant area of interest. Despite these advancements, there are still notable gaps in comprehending the integrated pathways and interactions at play across varying plant species facing chilling and freezing temperatures. Changes in lipid compositions, which are not yet well understood, present another critical area for investigation. A more robust understanding is needed to inform innovative strategies that improve plant growth under cold stress, particularly in addressing the challenges faced during reproductive stages.

This Research Topic aims to deepen the understanding of plant cold tolerance mechanisms and translate this knowledge into practical applications. By concentrating on cutting-edge research, this topic seeks to tackle vital questions surrounding epigenetic modifications in cold acclimation, the influence of climate change on cold stress responses, and the identification of novel genetic resources for breeding cold-tolerant varieties. This focus hopes to inspire collaboration and pioneering approaches to bolster plant resilience against cold stress. Additionally, we encourage integrated omics analyses to provide a comprehensive understanding of the plant response mechanisms, with an emphasis on genes associated with cold tolerance.

To gather further insights into plant cold tolerance, we welcome articles addressing, but not limited to, the following themes:

• Molecular and physiological mechanisms of cold acclimation and cold tolerance

• Role of signal molecules and hormones in cold stress responses

• Genes associated with cold tolerance

• Integrated omics analyses of cold stress responses

• Climate change and cold stress in plants

• Genetic and genomic approaches in breeding for cold tolerance, including epigenetic regulation

• Innovative technologies and the use of exogenous substances and beneficial microorganisms for enhancing cold resilience

We encourage a variety of article types, including original research, reviews, and perspectives, that contribute to a deeper understanding of plant cold tolerance.

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.

• Can I suggest a new Research Topic? 

  Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.
