[Sequence and structure analysis of mitochondrial tRNApro and tRNAthr genes in domestic goose breeds].
We report here the results of the sequence and structure analysis of mitochondrial tRNApro and tRNAthr genes in domestic goose breeds by sequencing the mitochondrial DNA from a total of 25 samples from 6 breeds of Chinese geese and 2 breeds of domestic Europe geese. Sequences and the cloverleaf structure of tRNApro (69 bp) and tRNAthr (68 bp) in domestic goose breeds were described and analysed They were compared amongst the three domestic goose breeds as well as between Anseriformes (Anser cygnoides) and Galliformes (Gallus gallus domesticus, Genbank accession number NC001323). Both goose tRNApro and tRNAthr genes have normal cloverleaf secondary structures. The amino acid arm and the anticodon loop of the cloverleaf structure of tRNApro and tRNAthr are very conservative among Anser albifrons, Anser anser and Anser cygnoides. The gene sequences in this study were deposited to GenBank under accession numbers AY427800-AY427805 and AY427812-AY427814.
