Team of Professor of Professor of the Professor of Yunnan Agricultural University discovered the characteristics of the origin of Lintang Pu'er tea

Recently, the reporter learned from the Yunnan Agricultural University that the team of Professor of the School of the School discovered the origin characteristics of Lintang Pu'er tea in Yunnan and published research papers.

In recent years, with the increase in people's demand for tea, the rapid development of the tea industry, the development of tea science, tea health function mechanism and new products at home and abroad have increased their efforts and achieved significant results. However, at present, the genetic resources of ancient tea trees and the characteristics of genes of genes have not been deeply excavated and utilized, leading to high genetic breeding costs and unstable quality of tea. It has become a problem that the development of the tea industry is urgent.

Lincang is the area with the most wild ancient tea trees in the world. The area of ​​ancient tea trees is 413,100 acres, accounting for 61%of the total area of ​​ancient tea trees in Yunnan, of which the wild tea tree area is 335,700 mu 5.984 million. 4850,400, scattered 17,000 plants. Yunnan Lincang has always been considered the origin and domestication of tea trees in the world, and contains rich ancient tea trees resources, but its genetic composition is little known.

Professor and Professor Dong Yang of Yunnan Agricultural University and Professor Dong Yang have proved that large -leaf breed tea is closer to wild tea in terms of genetic characteristics in terms of large -scale genomics. Professor Sheng Jun and Professor Dong Yang, with the support of the relevant departments of the Municipal Government of Lincang, led the team for 3 years to investigate all Pu'er tea in Lincang and the hills. More than 27,000 Pu'er tea samples of different altitude, different latitude and longitude, covering a total of 552 tea gardens, and establishing a large database of tea samples of ancient tea trees and ancient tea gardens. Precious materials.

According to a large number of tea samples collected, Professor Shengjun and Professor Dong Yang's team in the botanical journal "Frontiers in Plant Science" published a research paper entitled "Whole-Genome ResequenCing Revers The Origin of Tea in Lincang", revealing it The genetic characteristics of the origin and evolution of Lincang Pu'er tea. The study used short -reading long sequencing technology to carry out large -scale whole genome sequencing for 1350 different tea genomes. Studies have found that according to the population structure, Lintang Tea Tree is divided into three sub -groups, and it is inferred that the ancient tea gardens of Baiying Mountain in Izumo County, the former Gui and Nahan Tea Mountain, Fengqing Xiaowan Town Jinxiu Villa may be possible. The birthplace of tea trees. In addition, genetic diversity analysis has the height of the height of the tea tree group in Cangyuan area. Cangyuan tea species has become a potential resource for Pu'er tea selective domestication breeding.

Lei Yahui and Yang Ling of Yunnan Agricultural University Biological Bio -Data Key Laboratory were the first authors of the paper, Professor Sheng Jun and Professor Dong Yang as the corresponding author. This study was supported by the digital projects of biological resources. Through the discovery and analysis of this study, it is conducive to in -depth understanding of the evolution, genetic characteristics, and mutation direction of tea tree germplasm resources, and also provides basic data for digital analysis, digital design, and intelligent management of relevant information such as tea genomey. Lay the foundation for the promotion of the high -quality development of the Yunnan tea industry.
