TL;DR: It is found that genes that were retained as duplicates after the teleost-specific whole-genome duplication 320 million years ago were not more likely to be retained after the Ss4R, and that the duplicate retention was not influenced to a great extent by the nature of the predicted protein interactions of the gene products.

TL;DR: Higher- and lower-molecular-weight fractions of libraries are shown to contain distinct gene sets, and higher rates of gene discovery are associated with higher- molecular weight libraries.

TL;DR: The usefulness of the 16K microarray over a wide range of teleosts is demonstrated, even for transcriptome targets from species distantly related to salmonids, and BAC hybridizations are demonstrated as a rapid and accurate means to identify gene content.

TL;DR: The salmonid transcriptome reveals a complex history of gene duplication that is consistent with an ancestral salmonid genome duplication hypothesis, and genome resources, including a new 32 K microarray, provide valuable new tools to study salmonids.

TL;DR: Comparisons of duplicated genes show that while purifying selection is the predominant force acting on both duplicates, consistent with retention of functionality in both copies, some relaxation of pressure on gene duplicates can be identified.
