Construction of the first local pig resource gene bank in China

Introduction: at present, the most complete genome DNA library of local pig resources in China has been established in Jiangxi Agricultural University recently The library collected blood and tissue samples from 70 local pig breeds (groups) and more than 4000 pig individuals, and extracted and preserved 12000 DNA samples With a history of more than ten thousand years, China is the country with the most abundant pig resources in the world, and many local pig species have unique excellent gene resources This systematic collection work of Jiangxi Agricultural University not only preserved complete genomic DNA for pig resources in China, but also laid a material foundation for protecting and utilizing gene resources, identifying, separating and cloning new genes, and applying for "gene patent" in China A43 the establishment of genomic DNA library of local pig resources in China has prepared conditions for China's animal husbandry to cope with the challenge of entering WTO, which has far-reaching significance According to the person in charge of the Key Laboratory of animal biotechnology of Jiangxi Agricultural University, the establishment of DNA library is the basis of the research project of "main gene location of important economic characters of agricultural animals" undertaken by the University, which is the preliminary work of the national key basic research and development plan "973" project A43 it is reported that Jiangxi Agricultural University is actively engaged in the research of candidate genes for important economic traits in DNA library, and has achieved preliminary results A43 (author:) shared on feed Weibo to:
