    Reporters learned from Southwest University, the school silkworm genomic biology national key laboratory in france, Japan, the United States and other multi-national research institutions, the world's first fine genetic map of twill nightingach, and published on the 25th in the international authoritative journal
    . The results of this study reveal that the high-quality genome fine map of twill nighting oats, as well as the population variation map and gene expression map, can provide scientific basis for its prevention and treatment.
    According to the first author of the paper, Associate Professor Cheng Tingcai of the National Key Laboratory of Silkworm Genomic Biology of Southwest University, the twilled nightingach, also known as the oriental nightingadow, is a multi-eating and overeating agricultural pest that harms more than 300 species of plants in nearly 100 subjects, mainly in tropical and subtropical regions of Asia and Oceania. In recent years, the frequency of outbreaks in the Yangtze River basin and coastal areas of China has increased significantly, causing serious losses to agriculture, especially vegetable production.
    2012, the National Key Laboratory of Silkworm Genomic Biology of Southwest University launched the International Cooperation Project for the Sequencing of the TwillEd Nightingach Genome. Scientists from seven countries, including China, Japan, India, France, the United States, Thailand and Belgium, worked together to sequence and assemble the miter genome.
    Researchers first constructed a self-delivery line of more than 20 generations of twilled nightings, using single-person genome samples and whole-genome bird gun methods to sequence and assemble the twill nighting xenon genome, and obtained a fine map of the entire genome of twill nightingloids, including 31 chromosomes and more than 400 million bases.
    it is understood that the twilled nighting ostentat is the first pest in the scaly nightinger to obtain a fine map of the genome. Scaly fins are the second largest in the insect's outline, and most of the insects that fall for this purpose are pests. Cheng Tingcai said that the study not only explains the limited effect of chemical drugs in the prevention and control of twill nightings, but also provides theoretical guidance for the biological control techniques of twill nightings, and will also promote the biological research of other pests in the nightinger and provide assistance for pest control.
