News!Chinese scientists successfully deciphered naked oatl -based passwords

On the evening of July 18, Nature Genetics (Nature · Genetics) published a research paper "Based on the Reference Genome Revelation of the Six Bexy Oats of Oats" online, and wrote the research briefing "Cultivation of Oat Oats "Origin and Evolution" promoted the article.

A few days ago, the oatmeal research team led by Researcher Ren Changzhong, the chief scientist of the National Oatmeal buckwheat industry technology system and the president of the Baicheng Academy of Agricultural Sciences, Jilin Province first decipted the genome of naked oats, and studied the origin of six times the origin of oats. Advanced with the subunit, the "gene password chart" of oats is drawn.

It is understood that the research papers are mainly under the support of the national oat buckwheat industry technology system, the National Natural Science Foundation of China, the Talent Development Fund of the Organization Department of the Jilin Provincial Party Committee, and the Jilin Provincial Science and Technology Development Plan. The Academy of Sciences was completed by the core of oatmeal joint research team.

Oats are high -quality valley crops and important forage crops. They are not competing with traditional crops. Ren Changzhong believes that oats can play a unique role in dealing with food safety challenges. The study will accelerate the cultivation of oats and breeding of molecular design, which will produce an important role in improving the competitiveness of the oat industry and ensuring food security.

The result of this time is based on the local oats varieties of the naked oats origin center, and the 10.7GB of oatmeal genome 21 pairs of chromosomal molecular maps are drawn, annotating more than 120,000 protein encoding genes. Ren Changzhong, the author of the paper, believes that this work provides high -quality genome information and a brand new perspective for scientific researchers' analysis and domestication.

"As the origin and main planting center of naked oats in my country, we need to further tap the genetic resources represented by naked granular domestication by clarifying the genome information of naked oats." Professor Peng Yuanying, the main member of Sichuan Agricultural University, said, "With the genome map, the breeding and genetic research of my country's naked oats will enter the fast track."

According to reports, from the beginning of the new century, scientists have locked the goals of genomic sequences to crops. After a lapse of 20 years, the sequence of naked oatmeal influence was only resulting because the research of oat genome was extremely difficult.

Peng Yuanying said that the six -fold cultivation of naked oats was huge and complex, with a volume of about 40 times the rice genome, and about 87%of genomic DNAs were repeated sequences, which made it difficult to study its genome test assembly. The project team design selects the ultra -long sequencing technology that can perform a longer DNA fragment high -precision sequencing. Combined with different technical means, the chromosomal assembly, mounting and annotations are finally completed, and the high -quality reference genome of naked oats is obtained.

According to reports, according to the reference genome sequence and annotation information, the study predicted the key genetic sites related to the importance of naked seeds and disease resistance of oat skin, reflecting the important value of reference genome in important gene mining and oatmeal breeding.

The project team has a long -term expectation: the construction of oats reference genome as the first step in the age of the genome as an oat research will make the whole genome of oats a possible selection of breeding and precise breeding. "Now you can start considering how to use modern breeding strategies, such as genome editing, to further improve and develop specific oat varieties." Peng Yuanying said.

"The national oat buckwheat industry technical system team will further carry out research on the origin, domestication and excellent genetic resources of oatmeal origin, domestication, and excellent genetic resources." The wings of industrialization. "
