Cotton Genome Sequencing Completed Cotton Production Is Expected To Increase Significantly

< p > more than 70 scientists from 8 countries participated in the international cooperation project < a href= "http://www.91se91.com/news/index_c.asp" > cotton < /a > genome sequencing completed recently.

In December 20th, the academic article "polyploidy and fiber development of the cotton genome" was published in the British Journal of nature.

< p > it is reported that the team led by Wang Xiyin, Dean of the school of life sciences, Hebei United University, has been involved in the project since 2010, and is responsible for the research of comparative genomics.

< p > the article speculates that the completion of the project will promote the large-scale development of cotton related < a href= "http://www.91se91.com/news/index_cj.asp" > economic < /a >. The planting area of the world cotton field will exceed 32 million 900 thousand hectares, and the output of cotton will reach 24 million 900 thousand tons. The total amount of world cotton < a href= "http://www.91se91.com/news/index_s.asp" > trade < /a > will reach nearly 40 billion US dollars.

< p > Wang Xiyin said that there were three major discoveries in the study: first, the discovery of a polyploid ancestor of cotton; two, it was discovered that the ancestor species probably occurred in the extinction event that caused the extinction of dinosaurs 65 million years ago; and three, it was found that large scale gene replacement among different cotton groups in tetraploid cotton was found.

In addition, the project team also studied the function of genes related to cotton fiber development.

"The completion of genome sequencing is a landmark work for cotton biology research, which means that we can further study cotton quality optimization and yield improvement on a new platform."

< p > Wang Xiyin told reporters that the next task group will find out genes related to cotton fiber yield and quality, and achieve genetic improvement through hybridization and other technologies, cultivate new cotton varieties, and then go to field production to promote cotton economic development.

According to P, China is the largest cotton producing country and cotton producing country in the world, but in recent years, cotton production has been cut down by the virus.

All the genetic information obtained from genome sequencing helps to improve the yield and quality of cotton and other crops.
