Molecular characterization and phylogenetic analyses of the mitogenome of Wan-Xi white goose, a native goose breed in China.

ABSTRACT:

Background

The Wan-Xi white goose (WXG), an indigenous Chinese waterfowl (Anserini: Anserinae), is crucial for goose germplasm conservation. This study aimed to sequence and analyze the complete mitochondrial DNA (mtDNA) of WXG using the BGISEQ-500 platform. The mtDNA's structure and function were investigated to gain insights into its genetic diversity and population structure.

Results

The mtDNA was found to be 16,743 bp long and comprised 22 transfer RNA (tRNA) genes, 2 ribosomal RNA genes, a complement of 13 protein-coding genes (PCGs), as well as a single noncoding control region known as the D-loop. Notably, all tRNA genes, except for trnS1-tRNA which lacked the dihydrouridine stem, were predicted to adopt the typical cloverleaf structure. Given the genetic variability
