Abstract:

To discover the genetic diversity of Sujiang pig at molecular level,the complete mitochondrial genome of Sujiang pig was sequenced by next generation sequencing. The Sujiang pig had high genetic diversity in 15436 bps 37 genes,which A+T estimated percentage of 40%,C+G estimated percentage of 60% of its mitochondrial genome and tRNA had 8 mismatches. The Jianghai type mitochondrial nucleotide polymorphism was higher than the average level of the all six pig types,which revealed its unique genetic diversity. Phylogenetic analysis based on the complete coding region of the mitochondrial genome using NJ method,Sujiang pig was a separate pig among the six types of domestic pigs in China,and support its unique pig pedigree.
