Dear Colleagues,
Soil pollution is a serious global problem which makes the continuous monitoring of soil at all levels an absolute necessity. In recent years, the medical and veterinary use of antibiotics have contributed to their undesirable accumulation in the environment. Unlike more well-known pollutants (pesticides, detergents, fuels), pharmaceuticals are introduced into the environment constantly, although in low quantities. The presence of pharmaceuticals in soil, even in trace amounts, may point to the widespread problem of environmental pollution with pharmaceuticals. Most antibiotics, after being excreted by animals, are stable in the environment and may remain there for considerable periods. Therefore, it is necessary to know the reaction of plants to soil contamination with antibiotics. The reaction of photosynthetic apparatus to antibiotics is still not fully understood. Milestones in this field include, so far, the studies of the damages in photosystems I (PSI) and II (PSII), as well as the light-harvesting complex (LHCII), chlorophyll degradation to pheophytin by tetracycline, and the effective quantum yield of photochemical energy conversion in PSII.
Despite the rapidly accumulating information, there are still open questions and challenges in this fascinating field. For example, (1) are plants able to recover efficient photosynthesis after temporary uptake of antibiotics? (2) Is the regulation of gene expression an important element of plant adaptation to antibiotics or the recovery from antibiotic-induced damages? (3) How do antibiotic contaminants affect the activity of photosynthetic enzymes? How important are magnesium binding proteins in plant responses to antibiotic-caused soil pollution?

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.
