Special Issue Information

Dear Colleagues,

The plant holobiont includes an array of microorganisms from all domains of life that interact in a wide variety of ways with the host plant and with one another. These interactions can have an important effect on plant health and productivity. Studies of these interactions have typically focused on the negative impacts of plant pathogens and how they lead to decreased productivity and plant vitality. More recently, the less clear beneficial impacts of environmental microorganisms on plant health have become the focus of significant research. It is clear that individual microorganisms or microbial communities, often actively recruited by the plant through a variety of chemical messages (volatiles, root exudates, and others), can strongly support plant resilience to biotic and abiotic threats such as pathogens, insects, drought, and salinity. Analytical tools suitable for studying these interactions are becoming increasingly sophisticated, leading to important insights into beneficial plant–microbe interactions, along with microbial products intended to support plant growth and resilience (biofertilizers) or resistance to biotic threats (biocontrol agents). In this collection, we aim to highlight the vast array of scientific activity in this area, with a special emphasis on the discovery and application of microorganisms to support plant growth and resilience to biotic and abiotic stresses. We encourage the submission of high-quality manuscripts spanning the continuum from basic discovery, such as microbial community analyses that can identify microbial taxa and illuminate mechanisms of microbial community assembly, to application, including the use of individual microbes or defined synthetic communities to support plant growth. Comprehensive literature review articles, or manuscripts describing novel methods to address these questions, are also welcomed.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Low phosphorus (P) availability in tropical soils is one of the main constraints to agricultural productivity and the sustainability of cropping systems. In this study, we evaluated the functional potential of four bacterial strains, including those present in two commercial inoculants: Nodubiophos (Ag87-CCT 8090 and Ag94-CCT 8108), and Biomaphos (B119 and B2084), focusing on their production of phosphatase and phytase enzymes, organic acids, and their agronomic efficacy in soybean cultivation. In vitro assays showed that all strains exhibited phytase and both acid and alkaline phosphatase activities, with B2084 and Ag94 standing out in phytase-mediated mineralization. In contrast, B119 and B2084 showed the highest phosphatase activity. Organic acid production varied among strains and was influenced by the phosphate source, indicating a highly responsive metabolic regulation. Strains Ag87 and Ag94 were particularly effective in producing lactic, malic, and gluconic acids, displaying distinct profiles modulated by the available P source. In field trials, combined inoculation with Ag87 and Ag94 led to increased soybean yield, achieving performance comparable to conventional fertilization at 50% and 100% of the recommended P rate, despite applying only 30% of the total P. The results highlight complementary metabolic strategies among the evaluated strains, with the ability to solubilize and mineralize phosphorus through different mechanisms. They support their potential use as bioinoculants to enhance nutrient use efficiency and reduce fertilizer dependency in soybean cultivation. Full article
