Toxic effects of acetochlor, methamidophos and their combination on nifH gene in soil

Journal of Environmental Sciences, 2007
Toxic effects of two agrochemicals on nifH gene in agricultural black soil were investigated using denaturing gradient gel electrophoresis (DGGE) and sequencing approaches in a microcosm experiment. Changes of soil nifH gene diversity and composition were examined following the application of acetochlor, methamidophos and their combination.

The Klebsiella pneumoniae nitrogenase Fe protein gene (nifH) functionally substitutes for the chlL gene in Chlamydomonas reinhardtii

Biochemical and Biophysical Research Communications, 2005
The entire coding region of chlL, an essential chloroplast gene required for chlorophyll biosynthesis in the dark in Chlamydomonas reinhardtii, was precisely replaced by either the Klebsiella pneumoniae nifH (encoding the structural component of nitrogenase Fe protein) or the Escherichia coli uidA reporter gene encoding beta-glucuronidase.

[Study of nucleotide sequences of nifH genes in methanotrophic bacteria].

Mikrobiologiia, 2002
Using a previously developed primer system, nifH gene fragments 450 nucleotides long were amplified, cloned, and sequenced for representatives of nitrogen-fixing methanotrophic bacteria of the genera Methylococcus, Methylocystis and Methylosinus. Fragments of nifH genes were also detected and sequenced in representatives of the genera Methylomonas and ...

Organization of nifH and nifD genes in Nostoc commune UTEX 584

2021
Nostoc commune UTEX 584 is a photosynthetic desiccation-tolerant cyanobacterium capable of fixing nitrogen. Biotinylated nifH and nifD gene probes from Azotobacter vinelandii (a gift from Dr. Dennis Dean) hybridized to nifH and nifD sequences isolated from Nostoc commune UTEX 584.

Characterization of nifH gene expression, modification and rearrangement in Nodularia spumigena strain AV1.

FEMS microbiology ecology, 2011
The annually reoccurring blooms that characterize the surface waters of the Baltic Sea are dominated by filamentous, heterocystous cyanobacteria such as Nodularia spumigena. In a previous study, we have demonstrated that N. spumigena strain AV1 differentiates heterocysts in the absence of detectable nitrogen fixation activity, an unusual physiological ...

Bestimmung der Picoplanktondiversität und der Nitrogenase (nifH)-Gene im Nordatlantik

2002
Ziel dieser Diplomarbeit war es, die Diversität von stickstofffixierendem Picoplankton in oligotrophen Bereichen des Atlantiks zu analysieren. Dazu wurde DNA von Planktonorganismen größer als 0,1 μm extrahiert, die Gensequenz (nifH) der Nitrogenaseuntereinheit Dinitrogenase- Reduktase amplifiziert, kloniert und sequenziert.
