Coping with Pollution - the Effects of Environmental Contaminants on Plant Growth and PhysiologyEnvironmental contamination as a consequence of anthropogenic activities has become a global concern. Legislative changes and practices on a global scale surrounding soil, water, and atmospheric contamination require continued attention and development to mitigate damage. Cities, mining, industry, and certain agricultural practices, as well as improper waste disposal, are largely responsible for the undesirable release of hazardous compounds to the environment. These compounds, such as trace-elements, pharmaceuticals, and health care products, pesticides, as well as newly developed nanoparticles can negatively affect plant growth and physiology, including those of agricultural interest, causing adverse ecological and economic outcomes. Moreover, the response of plants to pollutants and contaminants requires investigation to assess the compound uptake, accumulation in the food chain, and the plant's capability to resist and ‘reclaim’ pollutants from contaminated environments. In this context, the identification of tolerance and sequestration mechanisms in plants to hazardous compounds can help the development of environmentally friendly technologies, i.e. phytoremediation, and support molecular approaches to increase plant tolerance to contaminants. In addition to contaminants, plants are challenged with changes in the environment arising from climate change, such as increasing temperatures, irregular rain patterns, and adverse light conditions. However, our understanding of the interactive effects between hazardous compounds and abiotic factors on plants remains limited.
This Research Topic aims to gather knowledge on plant responses to environmental contamination and the interaction with various scenarios of climate change, which is of critical importance for sustaining crop production. Studies can acknowledge the accumulation of contaminants in plants and the potential impacts in the food chain or at higher trophic levels. Papers focused on plant responses to emerging contaminants (pharmaceuticals and personal care products, persistent organic chemicals including pesticides, and harmful algal toxins) are of particular interest.
Original Research papers, Opinions, Perspectives, Hypotheses, Reviews, and Mini-Reviews related to the following topics in agricultural and non-agricultural plants are welcome for submission:
1) Plant physiological and morphophysiological responses to contaminants
2) Interaction of contaminants and abiotic factors in plant growth and physiology
3) Contaminant uptake and phytoremediation capacity of plants
Descriptive studies reporting responses of growth, yield, or quality to environmental contaminants will not be considered if they do not progress physiological understanding of these responses.
