Role of Plant Growth-Promoting Microbes in Agriculture—Volume II

Dear Colleagues,

By the end of the 1970s, the term plant growth-promoting rhizobacteria (PGPR) was coined to designate rhizosphere-isolated pseudomonads that, following seed inoculation, rapidly colonized plant roots and increased crop yield. The concept was adopted and developed by several researchers and, more recently, it was extended to any bacteria (PGPB) or any microorganism (PGPM) exhibiting plant growth-promoting (PGP) traits, such as nitrogen fixation, phosphate and potassium solubilization, the production of siderophores, indolic compounds, and 1-aminocyclopropane-1-carboxylate (ACC) deaminase or that lessen or prevent the deleterious effects of one phytopathogenic organism, and that is effective in benefiting plants. In addition to the formulation of conventional inoculants, studies with PGPM are evolving to the construction of synthetic communities, an approach that can be linked to metagenomic analysis, in order to identify the keystone taxa of soil microbiome and interfere in it to improve plant growth.

Previously, we successfully published a Special Issue on “Role of Plant Growth-Promoting Microbes in Agriculture” and received several papers from all over the world. We now therefore propose a “Volume II” of the same topic for a broader range of applications. This Special Issue welcomes all types of articles focusing on PGPM, including original research and reviews.

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.
