Advances in PGPR (Plant Growth-Promoting Rhizobacteria)

Dear colleagues,

Soil microbiota or microbiomes play an important role in different types of agrosystems. Among the members of the plant microbiota, plant mycorrhiza and plant-growth-promoting rhizobacteria bacteria (PGPR) interact in rhizospheric environments, leading to additive and/or synergistic effects on plant growth and heath. Mycorrhiza plays an important role in the improvement of nutrient uptake and provides tolerance to host plants against various stressful situations such as heat, salinity, drought, metals, and extreme temperatures or biocontrol of potential pathogens, under both normal and stressful conditions due to abiotic or biotic factors. Abiotic stresses hamper plant growth and productivity. Climate change and agricultural malpractices such as excessive use of fertilizers and pesticides have aggravated the effects of abiotic stresses on crop productivity and degraded the ecosystem. There is an urgent need for environment-friendly management techniques such as the use of mycorrhizal fungi for enhancing crop productivity. The present Special Issue provides comprehensive up-to-date knowledge on plant mycorrhiza in stressful agriculture and their influence on host plants at various growth stages, their advantages and applications, and consequently the importance of the relationships of different plant nutrients with mycorrhizae.

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.
