Published: 01 July 2004
...-polymerase chain reaction is a gene expression profiling technique that allows comparison of the effects of different chemicals on an organism. We used the restriction reaction to assess the potential of using stress responses of invertebrates to discriminate between different contaminants. Larvae...

...Krista M. Larsen; Leland J. Jackson; Sean M. Rogers The diatom Didymosphenia geminata can produce thick benthic mats along river bottoms, possibly in association with soluble reactive phosphorus mat-forming genetic variants, or gene expression associated with environmental variation. We isolated...

... gene (16S rDNA) sequences. Most of the analyzed 16S rDNA sequences were unrelated to any cultured and known uncultured microorganisms. Only two compost-derived 16S rDNA sequences from a total of 16 were related to known sequences at similarities higher than 97%, viz. , a species-level criterion. One...
