World's first giant panda genome sequence mapping completed

Chinese scientists announced on 11 November in Shenzhen: Panda-the world's first genome mapping is complete. Scientists say that it will protect and artificial breeding this is called the "China National treasure," endangered species provides a new way, as well as pushing for other scientific research on the giant panda.

In March of this year, sponsored by the Chinese scientist, Canada, United Kingdom, United States, Denmark and other countries, international scientists in genomics "giant pandas" project started, draw the genome sequence of the Giant Panda is the first part of the project, Shenzhen huada gene Research Institute undertook major work tasks.

Why is the Giant Panda "black eyes"? why bamboo Panda and black bear skins? is the next of kin? future what looks like a giant panda? Chinese scientists from genome level answer these tricky "issue", a selection of giant pandas "Crystal" genome sequencing, "Crystal" is the mascot of the Beijing 2008 Olympic Games, one of the prototypes has been living in the Chengdu giant panda breeding research base.

"Our research work great, if you write the giant genome sequence into a book, its thickness is equivalent to 384 m above the Shenzhen diwang building. "Shenzhen huada gene Research Institute said Dr Wang.

He said: "the study found that the Giant Panda has a total of 21 on chromosome, the size and the human genome, around 30 million base pairs that contain 2-3 000 genes. ”

The scientists used a new sequencing technologies drawing Panda genome sequence of the sequencing of the speed significantly increase, the cost is significantly reduced. Allegedly, this is the world's first to adopt this new technology complete the landmark large genome sequence of the genomics Institute of the autonomous development of the whole genome assembly software and independent structures of high-performance computers, playing a key role.

Jun Wang said, genome sequencing results support the "the Giant Panda is a subspecies of bears," point of view. Adoption and already had a whole genome sequencing of the species, the researchers also found that the giant panda genome and dog genome closest in structure, and also have greater similarity in mammals and larger differences in mice.

Scientists revealed that the in-depth research in progress.

Scientists said the giant pandas genome sequence of the drawing is complete, help from gene angle explains why Panda reproduction capability of questions, thereby enabling scientists have the opportunity to help breed more pandas.

Chengdu giant panda breeding research base, Director Hou-Jung said: "we believe that the study of the giant genome will be endangered species protection and artificial breeding provides a new way. ”

Shenzhen huada gene Research Institute Director, Academy of Yang Huan-ming, Shenzhen huada gene Research Institute will be completed during the year of the Giant Panda's genome, and fine figure and various cooperation units in genome level research on the giant pandas in the system.

He said that Chinese scientists of unremitting efforts, and through active participation in the international genetic research, study and China gene sequencing level will continue to improve the current genetic research international cooperation remain open, the door of the Chinese welcome more countries of the scientists involved.

Since 1999, officially joined the "international human genome project" Chinese scientists have participated in the "international human genome project," "international human haplotype plan" and other projects at the same time to complete a number of important plant and animal genome mapping, including rice, SilkWorm, chicken, pigs, etc., made important contributions. In October 2007, the first full Chinese genome completed successfully draw.

Panda genome sequence of drawing is a series of efforts by the latest results, the long-term goal of Chinese scientists is the selection of animals, plants and microorganisms represent species genome sequencing, Deputy for outside paint a complete, gorgeous "tree of life".

Participation in the study of Shenzhen University, Chinese Academy of Sciences, Beijing Genome Institute, Institute of Zoology, zhongkeyuandongwuyanjiusuo, Chengdu giant panda breeding research base, China Panda Research Center, Fudan University, the University of Hong Kong. It is reported, and Nankai joint implementation of the giant panda protein group function and structure of the research project is also about to start.

At present, the world's only remaining Panda around 1590 only, mainly in China's Sichuan province, the surrounding mountains, is known as the "living fossil". In addition, as of the end of 2007, China artificial Panda population up to 239 only.
