Microbiomes inhabiting rice roots and rhizosphere

First Insights into the Microbiome of a Mangrove Tree Reveal Significant Differences in Taxonomic and Functional Composition among Plant and Soil Compartments

“…In other model plants, both bacteria and fungi have been robustly detected in endospheres of plant organs, while the plants we examined were extreme in that we did not detect bacteria in endospheres of all their organs. Second, composition patterns of bacterial and fungal communities detected in the R. stylosa rhizosphere compartment differed from those of model plants reported in previous studies [10,[69][70][71][72]. Generally, Proteobacteria, Acidobacteria, Actinobacteria form the backbone of the bacterial rhizosphere microbiomes in the model plants.…”

“…Thus, the final goal of our work was to use R. stylosa as a model plant to investigate its microbiome and compare it to other model plants in other ecosystems [67], including: the general model plant Arabidopsis thaliana [68,69]; the model crop plants Oryza spp. (rice) [70,71] and Zea mays (maize) [72]; and the model forest tree genus Populus [10]. Overall, we found that the microbial communities of soil and plant compartments of R. stylosa had both unique and shared features with the other model plants.…”

“…In some specific soil types and locations, these two bacterial phyla also reportedly co-dominate the rhizosphere of Oryza spp. [70,71]. Third, Dikarya (Ascomycota and Basidiomycota) were the only fungi detected in the rhizosphere and endospheres (root, stem and leaf) of R. stylosa, while other, lower fungi, such as Zygomycota and Chytridiomycota, etc.…”

“…and Oryza spp., lower fungi of the Zygomycota even co-dominate the rhizosphere and/or root (in Populus spp.) microbiomes [10,71]. Locations, soil types, and environmental factors also strongly affect the taxonomic composition of bacterial and fungal communities at coarse and fine taxonomic resolutions in these model plants [69,70,[72][73][74].…”

From Isolation of Phosphate Solubilizing Microbes to Their Formulation and Use as Biofertilizers: Status and Needs

“…Sane and Mehta (2015) showed that phosphate solubilizing bacteria and fungi in co-inoculation increase the mobilization of rock phosphate and plant growth. Authors Zaidi et al (2017) and Ding et al (2019) reported that PSMs isolated from the rice rhizosphere released 22-826 µg P mL −1 in in vitro test. Among the PSMs, Actinobacteria (Actinomyces) are of special interest since these filamentous sporulating bacteria (see details in Box 2) are able to develop in extremely different soils and offering a unique opportunity for biotechnological application (Mengual et al, 2016).…”
