ABSTRACT
Objective Assembly whole mitochondrial genome sequence of Rongshui miniature pig ( RMP ) breed and analysis the structure of mitochondrion based on the next-generation sequecing method.Comparison of phylogenetic relationship and genetic diversity among different pig breeds.Methods We collected peripheral venous blood sample from RMP and constructed two paired-end sequencing libraries.A whole-genome shotgun sequencing strategy and Illumina Genome Analyser sequencing technology were used in our study.Results The mitochondrial genome of RMP consists of 13 protein coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and the length of pig is 16888 bp.The GC content of this pig mitochondrial genome is about 44 %.Based on phlogenetic analysis, population genetic analysis, our findings confirmed that the ancestral cluster in East Asia mainly occurred among Diannan 7#pig, Hainan wild boar, Lanyu and RMP.Conclusion RMP, a typical miniature pig breed in China, is an earlier ancestor than Lanyu pig breed.
ABSTRACT
Objective To establish the data including anatomy and histology of main organs in Rongshui miniature pig (RMP).Methods F1 Rongshui miniature pigs with male and female (2 in each group) in 6 month old were used in this experiment.We measured body weights, dissected these pigs after anaesthesia, recorded total blood volume, total plasma volume, number of spine and dental formula, took main organs for photographs, and made histological sections observed and took photographs by microscope.Results We gained the photographs of main organs and histological sections, organ weights,organic coefficients and other basic data.Conclusion Basic anatomy and histology data of main organs in RMP were collected.
