Determination of the phylogenetic relationships among Pacific salmonids by using short interspersed elements (SINEs) as temporal landmarks of evolution

The salmonid Hpa I short interspersed element (SINE) family is isolated and sequenced from the salmonid genomes. Amplification by PCR of the orthologous loci in the 12 fish, for each genomic locus representing the subfamily, is determined by the order of branching of the pacific salmonoid species. The three evolutionary lines, the line of the chum salmon, pink salmon, and kokanee, a line of coho salmon and chinook salmon and a line of steelhead trout reveal the existence of a phylogeny. There is also a change in the phylogenetic assignment of the steelhead trout from Salmo to Oncorhynchus.
