Agrogenomics Research Center
Animal Genome Research Unit
We are developing genomic resources of livestock animals and providing information to contribute in the development of high-quality, safe and secure livestock products. We have decoded more than 10,000 expressed genes (full length cDNAs) and cooperated in the International Swine Genome Sequencing Consortium. We also developed the methods for discrimination of breeds or individuals by using DNA polymorphism, and identified the genes responsible for the number of vertebrae and meat color in pigs. Now, we are increasing the accumulation of the genomic information in livestock animals such as pigs. We are also developing methods for detecting the association between gene polymorphisms and phenotype. With the effective utilization of genomic information, we are aiming to identify the genes responsible for meat quality, growth rate, disease resistance, reproductive performance, and other traits. We can use genomic information to develop gene markers that support rapid breed improvement for meat quality, productivity, and disease resistance. Management of production with the gene markers enables us to supply the variety of products corresponding to various needs of consumers.
- From the genome project to determination of gene polymorphism. Mammalian cells contain chromosomal (genome) DNA in which approximately 25,000 genes are located. Gene markers are developed by decoding the genome sequence and elucidating the polymorphisms affecting individual differences.
- Pork loins with various levels of intramuscular fat content. Gene markers will allow the effective production of pork traits to meet a variety of consumers' needs such as low fat and healthy pork, or fat-marbled and rich-tasting pork.
