Use of degenerate oligonucleotides for amplification of the nifH gene from the marine cyanobacterium Trichodesmium thiebautii

Abstract

Trichodesmium spp. are marine filamentous, nonheterocystous, nitrogen-fixing cyanobacteria which are an important component of marine ecosystems. This organism has never been maintained in axenic culture, and there has remained some doubt as to the identity of the organism responsible for nitrogen fixation in Trichodesmium aggregates. By using degenerate oligonucleotide primers, it has been possible to amplify, clone, and sequence a segment of the nifH gene from a natural assemblage of Trichodesmium thiebautii. Examination of the DNA and presumed amino acid sequence shows that the gene is most closely related to that of Anabaena spp. and therefore is most likely a cyanobacterial nifH gene. The use of degenerate oligonucleotides, in concert with the polymerase chain reaction, can be a powerful tool for the cloning and sequencing of a variety of genes from microorganisms in the environment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
