Chinese scientists crack the drug-resistant genome of grass-greedy nightings

Science and Technology Daily (Reporter Zhao Hanbin) Grassland greedy nightinger poses a great threat to China's food security production, understanding its genetic background and drug resistance is of great significance to the formulation of effective prevention and control strategies. Reporter October 28 from Yunnan Agricultural University learned that the university Shengjun professor team at home and abroad research institutions, the first time cracked the grass greedy nightingad drug-resistant genome. The results were published online October 27 in the international authoritative journal Protein and Cell.
grasslands are native to the Americas and host more than 350 species of plants, including more than 80 cash crops such as corn, wheat, sugar cane, rice, peanuts and chili peppers. In January 2019, the grass-green nightinger was moved into China from Myanmar and spread rapidly to 26 provinces and cities, with a cumulative area of more than 16 million mu. With the continuous expansion of the occurrence area, China's annual crop area of up to hundreds of millions of mu.
" grass greedy nightingado host plants, a wide range of suitable for life, strong reproductive capacity, fast flight diffusion, sudden hazards, difficult to prevent and control, let people talk about color change. Sheng Jun, president of Yunnan Agricultural University, told science and technology daily that they had carried out genetic sequencing and analysis of grass-green nightingads and their drug resistance in cooperation with Huada Gene,
Animal Institute and relevant institutions in the United States, South Africa, Ethiopia and Kenya.
team integrated multi-group techniques to sequence the chromosomal-level genome of the grass-green nightingado chromosome, the highest-quality genome of the worm released to date. Analysis shows that the invasion of China's grassland greedy nightingar cell pigment P450, anti-helixase and other gene families appeared significantly expanded, of which the P450 family as many as 425 genes, is the near edge of the species of twill nightingadow as many as three times, and 283 for the grass greedy nightingar.
", through 23 pesticide treatment, to study its drug-resistant molecular structure, we found the drug-resistant gene of this mule. Sheng Jun said.
