Characterization and Phylogenetic Significance of a Repetitive DNA Sequence from Whooping Cranes (Grus americana)

We surveyed a Whooping Crane (Grus americana) genomic library enriched for repetitive clones, and isolated a clone whose insert hybridized stringently to a repeated-DNA family in the genomes of Whooping Cranes, but not Sandhill Cranes (G. canadensis). This tandem sequence, repeated approximately 500...

Description
Summary:We surveyed a Whooping Crane (Grus americana) genomic library enriched for repetitive clones, and isolated a clone whose insert hybridized stringently to a repeated-DNA family in the genomes of Whooping Cranes, but not Sandhill Cranes (G. canadensis). This tandem sequence, repeated approximately 500 times in the Whooping Crane genome, displays taxon-specific properties suggesting that the Common Crane (G. grus) is the Whooping Crane's nearest living relative. Low-stringency hybridizations with this repeat produced conserved patterns in all cranes except crowned-cranes (Balearica), which indicates an early divergence of the crowned-cranes and the remaining cranes. Sequence and DNA-hybridization analyses imply that this repeat is a satellite sequence of similar complexity and organization to the primate alphoid DNA-sequence family, which also has chromosome and species specificity.
