Diagnosis and Management of Prenatal Hereditary Pyropoikilocytosis

Prenatal Diagnosis, EarlyView.
ABSTRACT Hereditary pyropoikilocytosis (HPP) is a severe hemolytic anemia caused by variants in SPTA1, SPTB, and EPB41. These weaken horizontal interactions in the erythrocyte cytoskeleton, causing membrane fragmentation and splenic sequestration. It will readily cause fetal anemia and often hydrops fetalis. Prenatal diagnosis requires first ruling out

Evidence for polyploidy in the globally important diazotroph Trichodesmium [PDF]

, 2016
Polyploidy is a well-described trait in some prokaryotic organisms; however, it is unusual in marine microbes from oligotrophic environments, which typically display a tendency towards genome streamlining.

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Diverse and Novel nifH and nifH -Like Gene Sequences in the Deep-Sea Methane Seep Sediments of the Okhotsk Sea [PDF]

Applied and Environmental Microbiology, 2009
ABSTRACT Diverse nifH and nifH -like gene sequences were obtained from the deep-sea surface sediments of the methane hydrate-bearing Okhotsk Sea. Some sequences formed novel families of the NifH or NifH-like proteins, of currently unresolved bacterial or archaeal origin.

Nitrogen Fertilization Has a Stronger Effect on Soil Nitrogen-Fixing Bacterial Communities than Elevated Atmospheric CO2 [PDF]

, 2014
Biological nitrogen fixation is the primary supply of N to most ecosystems, yet there is considerable uncertainty about how N-fixing bacteria will respond to global change factors such as increasing atmospheric CO2 and N deposition.

Enhanced CO2 Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient‐efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low‐nitrogen ...

The shifts of diazotrophic communities in spring and summer associated with coral Galaxea astreata, Pavona decussata and Porites lutea

Frontiers in Microbiology, 2016
The coral holobiont often resides in oligotrophic waters; both coral cells and their symbiotic dinoflagellates possess ammonium assimilation enzymes and potentially benefit from the nitrogen fixation of coral-associated diazotrophs. However, the seasonal

Influence of ammonium and moisture on survival and nifH transcription in the diazotrophic Pseudomonas mendocina S10

Notulae Scientia Biologicae, 2020
Nitrogen is important for crop productivity and usually added in form of urea into the soil which negatively affects the environment. It is important to utilize nitrogen fixing bacteria for improving the nitrogen content of soil in India.

Activity and interactions of methane seep microorganisms assessed by parallel transcription and FISH-NanoSIMS analyses [PDF]

, 2015
To characterize the activity and interactions of methanotrophic archaea (ANME) and Deltaproteobacteria at a methane-seeping mud volcano, we used two complimentary measures of microbial activity: a community-level analysis of the transcription of four ...

The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.
