Special Issue Information

Dear Colleagues,

“Rhizosphere Bacteria and Fungi that Promote Plant Growth” aims to recognize the critical role of microorganisms associated with plant root systems and their physical, chemical and biological interactions in promoting plant growth and health.

The influence zone of plant roots on their associated microorganisms and soil constituents is commonly known as the Rhizosphere. In this soil zone, the plant root system typically obtains nutrients through microbial activity and provides substrate for root-associated microbes through plant photosynthesis. Microorganisms, such as bacteria and fungi, are an important part of the soil system and are key to the breakdown of organic matter and the basis of nutrient cycling.

Before applying soil microbial techniques, it is crucial to understand the fundamentals of rhizosphere microbial ecology, such as the diversity and function of rhizosphere microbes.This Special Issue will focus on various aspects of microbial interactions, plant growth promotion by bacteria and fungi (endophytic or free-living), symbionts (mutualistic relationships) including nitrogen-fixing bacteria (Rhizobium), plant growth-promoting rhizobacteria (PGPR), associative or casual (free-living microorganisms), plant-microbe genetics and genomics, roles of soil microorganisms and their interactions with the plant microbiome interactions, nutrient availability, and mechanisms associated with plant growth promotion.

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. Microorganisms 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 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.

The deposition of nitrogen in soil may be influenced by the presence of different nitrogen components, which may affect the accessibility of soil nitrogen and invasive plant–soil microbe interactions. This, in turn, may alter the success of invasive plants. This study aimed to clarify the influences of the invasive plant Bidens pilosa L. on the physicochemical properties, carbon and nitrogen contents, enzymatic activities, and bacterial communities in soil in comparison to the native plant Pterocypsela laciniata (Houtt.) Shih treated with simulated nitrogen deposition at 5 g nitrogen m−2 yr−1 in four forms (nitrate, ammonium, urea, and mixed nitrogen). Monocultural B. pilosa resulted in a notable increase in soil pH but a substantial decrease in the moisture, electrical conductivity, ammonium content, and the activities of polyphenol oxidase, β-xylosidase, FDA hydrolase, and sucrase in soil in comparison to the control. Co-cultivating B. pilosa and P. laciniata resulted in a notable increase in total soil organic carbon content in comparison to the control. Monocultural B. pilosa resulted in a notable decrease in soil bacterial alpha diversity in comparison to monocultural P. laciniata. Soil FDA hydrolase activity and soil bacterial alpha diversity, especially the indices of Shannon’s diversity, Simpson’s dominance, and Pielou’s evenness, exhibited a notable decline under co-cultivated B. pilosa and P. laciniata treated with nitrate in comparison to those treated with ammonium, urea, and mixed nitrogen.
