“…In line with these findings, the indicator fungal species analysis of contamination identified four important mycorrhizal fungi, Rhizophagus, Funneliformis, Sphaerosporella , and Geopora. Rhizophagus , and Funneliformis , are well known AMF species associated with plant growth promotion (Wu et al, 2014 ; Padmavathi et al, 2015 ). Species of Geopora , been found to be the principal EMF colonists of willows planted for restoration in fly ash and have been hypothesized to survive well under harsh environmental conditions (Gehring et al, 2014 ).…”

The interaction between plants and microorganisms, which is the driving force behind the decontamination of petroleum hydrocarbon (PHC) contamination in phytoremediation technology, is poorly understood. Here, we aimed at characterizing the variations between plant compartments in the microbiome of two willow cultivars growing in contaminated soils. A field experiment was set-up at a former petrochemical plant in Canada and after two growing seasons, bulk soil, rhizosphere soil, roots, and stems samples of two willow cultivars (Salix purpurea cv. FishCreek, and Salix miyabeana cv. SX67) growing at three PHC contamination concentrations were taken. DNA was extracted and bacterial 16S rRNA gene and fungal internal transcribed spacer (ITS) regions were amplified and sequenced using an Ion Torrent Personal Genome Machine (PGM). Following multivariate statistical analyses, the level of PHC-contamination appeared as the primary factor influencing the willow microbiome with compartment-specific effects, with significant differences between the responses of bacterial, and fungal communities. Increasing PHC contamination levels resulted in shifts in the microbiome composition, favoring putative hydrocarbon degraders, and microorganisms previously reported as associated with plant health. These shifts were less drastic in the rhizosphere, root, and stem tissues as compared to bulk soil, probably because the willows provided a more controlled environment, and thus, protected microbial communities against increasing contamination levels. Insights from this study will help to devise optimal plant microbiomes for increasing the efficiency of phytoremediation technology.

“…Rhizophagus and Glomeraceae, both arbuscular mycorrhizae, were highest in grass, suggesting plant-specific interactions. Although previous studies have documented associations of Rhizophagus with both monocot and dicot crops suggesting low plant specificity [43][44][45]. We believe that in these savannah rangelands future investigations might confirm that these arbuscular mycorrhizae enable grass vigor which is a goal in rangelands Three phyla: Basidiomycota, Ascomycota, and Glomeromycota were significantly associated with pH based on Spearman's rank correlation (p<0.05).…”

Soil microbial communities depend on pH, texture, and available nutrients. Ashe juniper (Juniperus ashei) is encroaching on live oak (Quercus virginiana) savannas. Litter differences may alter soil microbial communities and therefore the ability of the soil ecosystem to cycle nutrients. The objective was to determine whether soil microbial communities differ under the canopies of Ashe juniper and live oak. At each of three transects we collected four surface soil samples under live oak canopy, overlapping canopies of live oak and Ashe juniper, under Ashe juniper canopy, and in grass away from the trees. We characterized soils by pH, texture, calcium carbonate equivalence, total nitrogen, and total carbon. Microbial communities were analyzed using massively parallel DNA sequencing and analyzed within QIIME using Kruskal-Wallis ANOVA, Mann-Whitney U, and Spearman's rank correlations. Prokaryotic communities differed along the transect, while fungal communities did not. Soil pH increased from live oak to grass. Trends in taxa were mostly associated with vegetation, pH, and CCE. Many prokaryotic genera associated with soil properties were important nutrient cyclers. Many fungal genera associated with pH and vegetation were mycorrhizal fungi, suggesting a plant-specific relationship.

“… Acinetobacter species isolated from soils have documented phosphate solubilization potential ( 66 ). Acinetobacter strains in association with plants have demonstrated growth-promoting ability, and shoot tissues have shown phosphate accumulation ( 67 , 68 ). A strain of Acinetobacter johnsonii isolated from surface-sterilized beet roots showed growth-promoting effects on seedlings, and plants had increased absorption of nitrogen, phosphorus, and potassium from the soil ( 69 ).…”
