Antioxidative and Chelating Molecules of Plants under the Excess of Metals

Dear Colleagues,

Common plant metabolites with antioxidative and/or metal chelating ability (such as vitamins C and E, thiols, organic acids, proline, and many else) are crucial in mediating the adaptation of plants to changing environments, including the excess of metals. Their exogenous application or genetic manipulation often ameliorates the negative effect of metals and modulates the yield of plants. On the other hand, some of these metabolites support the uptake of metals in (hyper)accumulator species, providing a tool for increased phytoremediation. In addition to toxic metals, essential plant metallic nutrients or beneficial elements may stimulate the accumulation of antioxidative molecules in plants, leading to products with higher health benefits. These interactions may positively affect the quality of crops and medicinal plants. Both laboratory and field studies focused on the interaction between antioxidants and metals (and vice versa) and subsequent molecular mechanisms in plants are welcomed.

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 250 words) can be sent to the Editorial Office for assessment.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
