Temperature‐Dependent Effects of Laboratory‐Heated Dissolved Organic Matter on Aquatic Microbiome Composition and Nitrogen Cycling Dynamics

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Wildfires generate partially combusted biomass that mobilizes to aquatic ecosystems as dissolved pyrogenic organic matter (dPyOM) in runoff, where it can impact surface water quality. However, the influence of dPyOM on aquatic microbiome composition, functional gene distribution, and biogeochemical processes remains poorly understood, with ...

An open reading frame upstream from thenifHgene ofKlebsiella pneumoniae

Nucleic Acids Research, 1983
An open reading frame upstream from nifHDK operon of Klebsiella pneumoniae had been described. The orientation of this open reading frame is opposite to that of nifHDK and sequence homology was found between the open reading frame promoter and the promoter of nifHDK operon.

Nitrogenase genes in PCR and RT-PCR reagents: implications for studies of diversity of functional genes

BioTechniques, 2003
Studies of the diversity of microorganisms in the environment have been facilitated by use of PCR and reverse transcription PCR (RT-PCR). Inhibition of the PCR by complex sample matrices and low abundance of some target microorganisms require the use of ...

Endophytic Expression of nif Genes of Azoarcus sp. Strain BH72 in Rice Roots

Molecular Plant-Microbe Interactions, 1999
Transcriptional fusions of gusA and gfp to the nifH gene as well as immunogold labeling with antibodies against the iron protein of nitrogenase revealed high nitrogenase gene expression levels of the endophyte Azoarcus sp.
