Special Issue Information

Dear Colleagues,

Many studies support the role of beneficial microbiomes for improving agri-food production and human health. Only during the last decade, we have begun to gain insights into the composition and functional of microbiomes as a consequence of major advances in High Throughput DNA sequencing (HTS) technologies. Microbiomes occupy a central position in the “One Health” framework. They can colonize almost all biological niches including plants and humans providing benefits to the planet as a whole and everything that lives on and in it. Plant-associated bacteria can be found in fact on leaves, roots or in the internal tissues as well as human-associated bacteria can reside on or within human. The application of beneficial microbes into agriculture can contribute to providing healthy food in a sustainable manner by reducing the amount of fertilizer, pesticides and herbicides. Given the food link, microbes from vegetable-diet can also have a direct and indirect effects on human health.

In this special Issue, we kindly invite the research community to submit original research papers and reviews that provide newest insights into the structure and dynamics of the core microbiomes across the food system (from soil to plants, and from foods to human) and to better investigate how we can use or manipulate microbiomes for achieving enhanced crop production and/or improving human health.

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 papers will be 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 2000 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.

Duckweeds are small, fast growing, and starch- and protein-rich aquatic plants expected to be a next generation energy crop and an excellent biomaterial for phytoremediation. Despite such an importance, very little is known about duckweed–microbe interactions that would be a key biological factor for efficient industrial utilization of duckweeds. Here we first report the duckweed growth promoting ability of bacterial strains belonging to the phylum Acidobacteria, the members of which are known to inhabit soils and terrestrial plants, but their ecological roles and plant–microbe interactions remain largely unclear. Two novel Acidobacteria strains, F-183 and TBR-22, were successfully isolated from wild duckweeds and phylogenetically affiliated with subdivision 3 and 6 of the phylum, respectively, based on 16S rRNA gene sequence analysis. In the co-culture experiments with aseptic host plants, the F-183 and TBR-22 strains visibly enhanced growth (frond number) of six duckweed species (subfamily Lemnoideae) up to 1.8–5.1 times and 1.6–3.9 times, respectively, compared with uninoculated controls. Intriguingly, both strains also increased the chlorophyll content of the duckweed (Lemna aequinoctialis) up to 2.4–2.5 times. Under SEM observation, the F-183 and TBR-22 strains were epiphytic and attached to the surface of duckweed. Taken together, our findings suggest that indigenous plant associated Acidobacteria contribute to a healthy growth of their host aquatic plants. Full article
