16S rDNA Profiling to Reveal the Influence of Seed-Applied Biostimulants on the Rhizosphere of Young Maize Plants [PDF]
, 2018 In an open field trial on two agricultural soils in NW Italy, the impact of two seed-applied biostimulants on the rhizosphere bacterial community of young maize plants was evaluated.

Drought Stress Results in a Compartment-Specific Restructuring of the Rice Root-Associated Microbiomes. [PDF]
, 2017 Plant roots support complex microbial communities that can influence plant growth, nutrition, and health. While extensive characterizations of the composition and spatial compartmentalization of these communities have been performed in different plant ...

Isolation of planctomycetes from Aplysina sponges [PDF]
Aquatic Microbial Ecology, 2003 There is mounting molecular evidence that bacteria belonging to the phylum Plancto- mycetes are abundant in marine sponges including members of the genus Aplysina. In an attempt to culture planctomycete bacteria from Aplysina sponges, 116 bacterial strains were isolated on selec- tive oligotrophic media.

Highly diverse nirK genes comprise two major clades that harbour ammonium-producing denitrifiers [PDF]
, 2016 Background: Copper dependent nitrite reductase, NirK, catalyses the key step in denitrification, i.e. nitrite reduction to nitric oxide. Distinct structural NirK classes and phylogenetic clades of NirK-type denitrifiers have previously been observed ...

Planctomycetes and eukaryotes: A case of analogy not homology [PDF]
BioEssays, 2011 AbstractPlanctomycetes, Verrucomicrobia and Chlamydia are prokaryotic phyla, sometimes grouped together as the PVC superphylum of eubacteria. Some PVC species possess interesting attributes, in particular, internal membranes that superficially resemble eukaryotic endomembranes. Some biologists now claim that PVC bacteria are nucleus‐bearing prokaryotes

Abundant Trimethylornithine Lipids and Specific Gene Sequences Are Indicative of Planctomycete Importance at the Oxic/Anoxic Interface in Sphagnum-Dominated Northern Wetlands [PDF]
, 2015 Northern wetlands make up a substantial terrestrial carbon sink and are often dominated by decay-resistant Sphagnum mosses.Recent studies have shown that planctomycetes appear to be involved in degradation of Sphagnum-derived debris.

Isolation of Gemmata-like and Isosphaera-like planctomycete bacteria from soil and freshwater [PDF]
, 2002 New cultured strains of the planctomycete division (order Planctomycetales) of the domain Bacteria related to species in the genera Gemmata and Isosphaera were isolated from soil, freshwater, and a laboratory ampicillin solution. Phylogenetic analysis of

Niche-directed evolution modulates genome architecture in freshwater Planctomycetes [PDF]
The ISME Journal, 2019 Abstract Freshwater environments teem with microbes that do not have counterparts in culture collections or genetic data available in genomic repositories. Currently, our apprehension of evolutionary ecology of freshwater bacteria is hampered by the difficulty to establish organism models for the most representative clades.

Anoxic nitrification in marine sediments [PDF]
, 2004 Nitrate peaks are found in pore-water profiles in marine sediments at depths considerably below the conventional zone of oxic nitrification. These have been interpreted to represent nonsteady- state effects produced by the activity of nitrifying ...

Planctomycetes in Lakes: Poor or Strong Competitors for Phosphorus? [PDF]
Applied and Environmental Microbiology, 2014 ABSTRACT Experiments were conducted with water samples from two perialpine lakes with differing eutrophication status in order to examine the effects of inorganic-nutrient amendments (nitrogen as NO 3 − or NH 4 + and phosphorus as PO 4
