Project description:Since CNVs play a vital role in genomic studies, it is an imperative need to develop a comprehensive, more accurate and higher resolution porcine CNV map with practical significance in follow-up CNV functional analyses To detect CNV of pigs, we performed high density aCGH data of diverse pig breeds in the framework of the pig draft genome sequence (Sscrofa10.2) 9 Chinese indigenous pig, one Chinese wild boar and 2 commercial pigs were detected using one pig of Duroc as reference. These 12 animals include 1 wild pig, 2 pigs each from Yorkshire and Landrace as the representatives of modern commercial breeds and 9 unrelated individuals selected from 6 Chinese indigenous breeds (2- Tibetan pig, 2- Diannan small-ear pig, 2-Meishan pig, 1- Min pig, 1-Daweizi pig, and 1-Rongchang pig).

Project description:This study is the first to report a genome-wide comparative DNA methylation map of adult pig sperm in three commercial pig breeds using WGBS technology. Our results showed that DNA methylation was more conserved in the three commercial pig breeds. Moreover, our results indicated that breed-specific HMRs are related to phenotypic changes and economically complex traits for each breed. The conserved HMRs between pig sperm and testis close to or located in the promoter regions of important genes are mainly involved in DNA repair and spermatogenesis.

Project description:Genome-wide SNP genotyping array can genotyped SNP highthroughly. It can be used in many aspects, such as phylogeny relationships, genome-wide association studies, copy number identification. 9 Chinese indigenous pig, 4 commercial pigs and 1 wild pig were genotyped by PorcineSNP60 array (Illumina) for exploring the phylogeny relationships among them.
Project description:Pig breeds have different attitude to traits like growth rate, carcass composition and reproduction parameters as well as other traits. These traits considered as external traits or end phenotypes are the outcome of complex biological processes and interactions. The main goal of pig breeding programs and the basis for crossbreeding is finding a balance between these traits. In pig production, Large White and Duroc breeds are commonly used to optimise respectively fertility and growth ability and differ on several production traits, indeed the first breed as a high fertility characters whereas Duroc is used as terminal sire for her growth performance and good carcass quality traits. In this study, we have used a quantitative label-free LC-MS proteomics approach to characterise and compare the liver proteome of two heavy Italian pig breeds, Italian Duroc and Italian Large White to identify difference due to their different genetic background. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 703094.

Project description:We performed transcriptome analysis of the longissimus dorsi muscle of four pig breeds (L, LDPL, DPL, DLDPL). This study provides a reference for exploring transcriptome regulation mechanisms affecting muscle growth and development in different pig breeds.
