Journal ArticleDOI
DNA barcoding: how it complements taxonomy, molecular phylogenetics and population genetics
TL;DR: It is suggested that DNA barcoding can complement current research in these areas by providing background information that will be helpful in the selection of taxa for further analyses and provide a unique 'horizontal' genomics perspective with broad implications.
Journal ArticleDOI
A universal DNA mini-barcode for biodiversity analysis
Isabelle Meusnier,Gregory A. C. Singer,Jean-François Landry,Donal A. Hickey,Paul D. N. Hebert,Mehrdad Hajibabaei +5 more
TL;DR: A novel approach based on a much shorter barcode sequence is established and demonstrated its effectiveness in archival specimens, which will significantly broaden the application of DNA barcoding in biodiversity studies.
Journal ArticleDOI
Environmental barcoding: a next-generation sequencing approach for biomonitoring applications using river benthos.
TL;DR: The results indicate the potential of an environmental barcoding approach for biomonitoring programs and show the ability of 454 pyrosequencing of mini-barcodes to accurately identify all species with more than 1% abundance in the pooled mixture.
Journal ArticleDOI
Nucleotide Bias Causes a Genomewide Bias in the Amino Acid Composition of Proteins
TL;DR: The nucleotide contents of several completely sequenced genomes are analyzed, and it is shown that nucleotide bias can have a dramatic effect on the amino acid composition of the encoded proteins.
Journal ArticleDOI
Synonymous codon usage is subject to selection in thermophilic bacteria
TL;DR: Both phylogenetic history and lateral gene transfer are eliminated as possible explanations for the characteristic pattern of codon usage among the thermophiles and a clear link between a particular pattern ofcodon usage and an external selective force is demonstrated.
