Heavy metals stress poses a severe threat to the growth and productivity of crops. The transfer of heavy metals from soil to crop plants is of major concern since it may result in bio-magnification across the food chain, resulting in a variety of negative consequences for consumers. In nature, plants are utilizing various mechanisms to combat the adverse effects of heavy metals. Plants respond to heavy metal toxicity by modulating their physiological, biochemical, and molecular status. In response to heavy metal stress, plant induces signals transduction pathways such as reactive oxygen species (ROS), reactive nitrogen species (RNS), hydrogen sulfide, and melatonin to trigger their defense mechanisms. In addition, the defense system of the plants against heavy metal stress could also be improved by the exogenous application of potential chemicals. Moreover, the association between plants and symbiotic microorganisms such as microbial plant biostimulants (MPBs) is a sustainable strategy to augment plant growth and productivity. Several different microorganisms can be used as MPBs to enhance plant growth and produce progressive and reproducible effects on horticultural crops. The present SI will focus on the consequences and mitigation strategies of heavy metal stress-associated damages on crop plants.

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. Agriculture is an international peer-reviewed open access monthly 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.
