Nitrogenase nifH Sequence Database

Current nifH Sequence Database

The full ARB database can be downloaded here nifH_database_2012.arb.

A fasta version contining only aligned nifH sequences is also available nifH_database_2012.fasta.

Evaluation of nifH PCR Primers

Using an earlier version of the nifH database (nifH_database_2010_07_14.arb) we performed a systematic evaluation of PCR primers that target the nifH gene to determine their utility for the study of diazotroph diversity and ecology (Gaby & Buckley, 2012).

Evaluation of nifH Diversity

Using an earlier version of the nifH database (nifH_database_2_4_09.arb) we perfored a systematic evaluation of nifH sequence diversity as a function of sequence phylogeny and environmental origin (Gaby & Buckley, 2011)
