Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress
Ecological Research, Volume 41, Issue 5, September 2026.This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Cloning and sequencing of the nifH gene of Desulfovibrio gigas
, 1989 The Desulfovibrio gigas nifH gene has been cloned and sequenced. It consists of an open-reading frame of 822 base pairs encoding a 274 amino acid polypeptide. A potential ntrA-dependent promotor sequence is present.

Amplification, cloning, and sequencing of a nifH segment from aquatic microorganisms and natural communities [PDF]
, 1991 By use of the polymerase chain reaction and degenerate oligonucleotide primers for highly conserved regions of nifH, a segment of nifH DNA was amplified from several aquatic microorganisms, including an N2-fixing bacterium closely associated with the ...

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.
