Dear Colleagues,

Soil contamination is becoming a problem in agriculture; it diminished the cultivable areas, and reduces crop yield and crop quality. The continuous growth of the human population increases the demand for food and energy crops, and therefore, the need for more cultivable areas. At the same time, urban, industrial, and agricultural practices release increasing amounts of contaminants into the environment. Polluted soils are considered useless for agriculture, not only because of the presence of contaminants that can alter food properties, but also because plants frequently cannot thrive or they grow very poorly on them. The utilization of contaminated soils for the production of energy crops could be a good solution to avoid the problems associated with the adsorption of contaminants in food crops, although how to achieve a high vegetal productivity in these contaminated environments remains a problem.

Because of the high cost of conventional remediation techniques, many contaminated areas are not included in remediation plans. Bioremediation is a promising technology that can be used in the rehabilitation of agricultural soils because it is a relatively cheap technique. The utilization of bacteria associated with plants, mainly in rhizoremediation strategies, presents many advantages, such as increasing the number and the activity of contaminant-degrading bacteria, and improving plant growth.

This Special Issue will focus on “Bacteria–plant interactions during bioremediation”. We welcome reviews, opinions, and novel research manuscripts covering all related topics, including, but not limited to, the following : (i) selection of the best combination plant–bacteria for decontamination processes; (ii) stability of the associations during bioremediation; (iii) identification of possible toxic contaminant-derived products and accumulation in soil; (iv) environmental impact of bioremediation activities; (v) economic viability of the bioremediation, including the utilization of the contaminant areas for the production of energetic crops; (vi) beneficial effects of bioremediation in plants; or (vii) characterization of root exudates and their influence in the expression of contaminant-degrading genes. This Issue will have special interest in works using energetic crops in bioremediation (poplar, sunflowers, and others).

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. Agronomy 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.
