Special Issue Information
Dear Colleagues,
Many metal and metalloid elements are essential for plant growth or can influence development in various ways, having a direct influence in plants’ primary and secondary metabolism. Conditions of deficiency or toxicity of metal/metalloid elements can lead to impaired metabolic functions in plants due to the lack, or altered function, of key proteins, leading, ultimately, to extensive oxidative damage. Plants react to these conditions by regulating one of the most effective stress-countering mechanisms available to living organisms: the antioxidant response. Plants deploy complex arrays of enzymatic and non-enzymatic antioxidant defense systems to counteract the accumulation of reactive oxygen species that results from metal/metalloid stress and that induces oxidative damage in shoot and root systems. Understanding how these mechanisms shape the plant's response, from the physiological to the molecular level, can provide important information on strategies to mitigate pollution in threatened ecosystems, implement bioremediation strategies and develop greener agricultural practices.
This Special Issue is devoted to the latest research on plant antioxidant mechanisms, including those promoted by beneficial microorganisms (e.g., plant-growth-promoting bacteria, arbuscular mycorrhizal fungi), developed to counteract metal/metalloid stress, providing insight into the conditions of element deficiency or toxicity. Original research articles and reviews are welcome. Research areas may include, but are not limited to, plant–microbe interactions, plant biochemistry and physiology, cytology and histology, genetics and molecular biology.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
