Xinhua News Agency, Washington, March 1 - Two teams of scientists from different countries announced on the 1st that they will draw a chicken genome sequence map and a genetic difference map. These two results will be available in areas such as bird flu prevention, improvement of poultry and human health, etc. Value. The genetic mapping of chickens was mapped by the Beijing Institute of Genomics, Chinese Academy of Sciences. In a press release, the National Institute of Human Genome Research of the United States stated that under the funding, a team led by Dr. Wilson of the University of Washington, USA, has worked successfully for the first time to map and assemble a chicken genome sequence sketch. This is the first sketch of the genome sequence of the bird species that has been completed to date. The scientists chose the ancestor of the chicken - the red chicken was the object of mapping. The sketch drawn contains about 1 billion base pairs. Scientists have stored chicken genome sequence sketch data in public databases for use by biomedical and agricultural researchers around the world. In addition, they also collaborated with the chicken genome sequence sketches and human genome sequence maps, which facilitated the use of specific browsing tools for comparative genomic analysis by other researchers. According to the National Human Genome Research Institute of the United States, under the leadership of the Beijing Institute of Genomics, Chinese Academy of Sciences, a group of scientists from China, the United Kingdom, Sweden, the Netherlands, Germany, and the United States also announced on the 1st that they have drawn a genetic map of chickens. . This map uses the genome sequence of the red primordial chicken as a frame of reference to sequence the genomes of three broiler chickens, laying hens, and black broiler chickens from the United Kingdom, Sweden, and China, and identifies about 2 million heritables based on this. Differences, the vast majority of which are single nucleotide polymorphism sites. This map of genetic differences in chickens will soon be deposited in public databases. In addition to playing an important role in human diet and economic development, chickens are also widely used in biomedical research. Chicken is one of the most important model organisms for studying embryos and development. From an evolutionary point of view, chickens are also an ideal medium for studying mammals such as lower vertebrates and humans. Comparing the human genome with the genomes of other organisms such as chickens helps us to understand more deeply the structure and function of human genes and to develop new methods for treating diseases. Scientists said that the successful mapping of chicken genome sequences and genetic differences maps paved the way for the use of chicken as a model to study vertebrate evolution, breed quality chicken breeds, improve food safety, and enhance human health. The new results have also been used in the area of ​​prevention of avian influenza, for example, from the perspective of genetic differences to study the susceptibility of different chicken species to the bird flu virus.
