After 7 years, the Grassland Institute of the Chinese Academy of Agricultural Sciences has constructed the world's first whole genome map of Leymus chinensis |
The end of 2014, by the China Agricultural Academy Grassland Research Institute (referred to as "Agricultural Research Institute chinensis whole genome sequencing project led by the Prairie") start
.
Seven years later, the state media of Inner Mongolia disclosed the news that the world's first whole genome map of Leymus chinensis has been completed
Academy of Sciences
It is micro-channel public number "Inner Mongolia Daily" news: June 30 in the morning, Inner Mongolia Autonomous Region Party Committee deputy secretary , chairmen of autonomous regions cloth Kobayashi came to China Agricultural Science Institute of Funchal Qin prairie pastoral area pilot demonstration bases, research prairie grass Technology Innovative work
.
According to the news, in the screening area of new Leymus chinensis varieties, Bu Xiaolin asked carefully about the preservation and improvement of forage germplasm resources, had an in-depth understanding of the breeding situation of new Leymus chinensis varieties, and had a cordial conversation with scientific researchers
.
The Grassland Research Institute has established a gene bank with the largest coverage of genetic diversity of Leymus chinensis germplasm in the world and the richest germplasm resources, and constructed the world's first complete genome map of Leymus chinensis
Bu Xiaolin affirmed the achievements of the Institute, and encouraged everyone to do a better job in protection and innovative utilization of grass germplasm resources, enlarge and strengthen the national forage germplasm resources bank, and effectively improve breeding innovation and improved breeding ability, and promote the realization The source of important forage grasses is autonomous and controllable
.
Leymus chinensis is a perennial rhizome-type herb belonging to the genus Leymus of the Gramineae family
.
Chinensis genome sequencing project started seven years ago by farmers ASTRI the lead prairie, joint agricultural ASTRI Shenzhen Institute of Agricultural genome units to work together
Academy of Sciences
According to a report from Xinhua News Agency on November 18, 2014, the Leymus chinensis whole genome sequencing project has been fully launched recently
.
The plan will fill the gaps in grassland plant genome research and strongly promote the healthy development of grassland ecosystems, biodiversity, grassland improvement, and grassland animal husbandry
The report pointed out that Leymus chinensis is mainly distributed in the temperate grasslands of Eurasia, and it accounts for about 50% of the total distribution area in China.
It plays an important role in maintaining the stability of the grassland ecosystem, biodiversity, and grassland productivity in northern China.
.
It is one of the main promoters of this sequencing project, when he was agriculture ASTRI prairie director JOJURNAL introduced, the source of the genome of L.
chinensis, phylogenetic relationships and status, the lack of strong evidence for the origin of species so far; grassland degradation associated with sheep Low seed setting rate, low germination rate, low reproduction rate and other “three lows” problems, ecological plasticity, and grazing degradation have long troubled its rational development and utilization.
The biological information extracted from the whole genome sequence can solve many of the above.
The problem provides strong evidence
.
At the same time, after the whole genome of Leymus chinensis is sequenced, the massive ecological function information contained in it will greatly promote the development of forage genome and grassland ecological genomics
Academy of Sciences
It is worth mentioning, was born in October 1963 in JOJURNAL retiring in September 2018 Agricultural Research Institute prairie post of director, currently serves as the director of the Institute was born in December 1971, with Ghent, Belgium Jin Ke from the University of Applied Biology Doctorate
.
According to farmers ASTRI grasslands official website, the institute was established in 1963, is located in Hohhot, capital of Inner Mongolia Autonomous Region Wulanchabu East Street, Saihan District 120, is a national research institute specializing in the study of grass, is the only The central government is stationed in the autonomous region of the department-level scientific research institution (the second category of public welfare)
.
The institute has won 4 national awards for grassland machinery and equipment in the pilot experiment research of the grassland forage-livestock balance dynamic monitoring system in northern China, the research and formulation of the national main cultivated forage seed quality classification standards, and the grassland machinery and equipment, accounting for 4/ of the national grassland industry awards.
