Heavy Metal-Induced Plant Stress: Toxicity, Tolerance Mechanisms and Homoeostasis

Dear Colleagues,

Heavy metals (HM) such as cadmium (Cd) and chromium (Cr) are toxic to humans, animals, and plants. Additionally, their non-biodegradable nature potentiates their accumulation in the environment and subsequent entrance into food chains, as they are taken by plants. Plants, due to their sessile nature, are strongly affected by the high levels of HM in the environment. Because HM contamination is growing worldwide, leading to major reductions in arable land, it is necessary to understand the tolerance or accumulation mechanisms of plants to HM, its effects on their primary metabolism, and different measures possible to be used to mitigate those negative effects, so that actions can be put into practice to maintain crop production in the future.

This Agronomy Special Issue will welcome contributions in the abovementioned fields of interest, including HM uptake and accumulation in plant tissues, HM homeostasis, and its effects in carbon, nitrogen, and oxidative metabolisms.

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. Agronomy 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 2600 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.
