Plants and Micro-Nanoplastic interactions: from single cells to the whole organism

About this Research Topic

Background

Plastic production, growing exponentially since the 1950s, has surpassed that of most of man-made materials, declaring plastics the main geological marker of the so-called “Anthropocene”. Taking into account all the plastics produced so far, only 9% have been recycled and another 12% incinerated. The rest has not been managed, having been dumped in landfills or the natural ecosystems, with a global distribution from terrestrial to freshwater, marine and atmospheric environments.

Once in the different environments, plastics undergo ageing, may leach toxic components and breakup in micro- and even in nano-plastics. Therefore, it is particularly urgent to study how micro- and nano-plastics interact with different plant species, both indirectly, by altering the physico-chemical properties of the growth medium, included plant-associated microbial communities, and directly, being also potentially taken up by plants and consequently altering their cellular physiology, growth, development, and productivity.

This special Issue of Frontiers in Plant Science welcomes the submission of original papers, short communications and reviews presenting research focused on the interaction between micro/nano-plastics and higher plants to enrich scientific literature, being many questions still outstanding on the subject. Current literature suggests influences of micro/nano- plastics on plants at different levels of organization, from the cellular and subcellular levels to the whole organism, but several aspects need clarification. Among them, the possible pathway for the uptake, the movement of plastics inside plants and the molecular mechanisms of their effects on cellular metabolism, structure and ultrastructure are of particular
interest. Manuscript dealing with the effects of these plastic materials on germination, growth, whole plant and cellular metabolism are needed to clarify the potential risks caused by micro/nano plastics, depending on their size, charge, polymer type, way of exposure, and by their interactions with other environmental pollutants, in short- and/or long-term treatments.

Research topic on the following topics, but not limited to:

- Advanced approaches for assessing toxicological profiles of nano and microplastics at cellular and whole plant level

- Genetic and epigenetic changes as plant response to nano and microplastics exposure

- Effects of nano and microplastics on cell physiology and cell’s redox status

- Cellular damages induced by nano and microplastics

- Uptake and translocation mechanisms of nano and microplastics in different cellular compartments and plant organs

- Interactions of nano and microplastics with cell wall and membranes

- Nano and microplastics as carriers for other pollutants hazardous for plant cells

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.
