China's first complete genome sequence of endangered species of white-headed langur |
China News Service, Nanning, May 11 (Jiang Weimin, Zhang Lei) Information provided by the Guangxi Forestry Bureau on the 11th shows that China has obtained the entire genome sequence of an endangered species of white-headed langur for the first time, revealing that the white-headed langur can be used in high alkalis rich in mineral ions.
The white-headed langur is a unique biological species in China.
Recently, the Guangxi Terrestrial Wildlife Rescue Research and Epidemic Disease Monitoring Center as the first author unit, Guangxi Medical University, Guangxi Chongzuo White-headed Langur National Nature Reserve Management Center and many other units have participated in the third-generation gene Sequencing method Completed the whole genome sequencing work of the white-headed langur, a national first-level protected animal, sequenced the mRNA transcriptome of some tissues and organs, obtained the most complete whole-genome sequence of the white-headed langur for the first time, and performed corresponding gene functions and expressions analysis.
The results of the study showed that the white-headed leaf monkey contains 22 pairs of chromosomes, which is 1 pair less than the 23 pairs of chromosomes in humans.
The research result ``White-headed langur reference genome and transcriptome analysis reveals the expansion of its alkaline tolerance-related genes'' paper was published in the BMC Biology of the Science Citation Index (SCI) on April 8, 2021 Periodical.
According to reports, in the 1980s, the number of white-headed langurs fell to less than 300.
