Successfully drew the first two-dimensional map of harmful mutations in potato; construct the first pan-genome of maize breeding inbred lines; The discovery of the molecular switch of iron transport in maize grains provides theoretical support for solving the problem of iron and other trace elements and cultivating iron-rich crop varieties. Explain the mechanism of avian influenza virus adaptation to mammalian hosts......Major original discoveries in China's agricultural science and technology are constantly emerging
This is the news that the reporter learned from the 2024 work conference of the Chinese Academy of Agricultural Sciences held recently. At the meeting, Wu Kongming, a member of the Party Group of the Ministry of Agriculture and Rural Affairs and President of the Chinese Academy of Agricultural Sciences, introduced that he would vigorously promote the reform of the system and mechanism of "lifting the academy to grasp major events", and make new progress in scientific and technological innovation of the Academy of Agricultural Sciences in 2023: the whole academy published 4681 articles included in SCI EI, an average increase of 2% over the previous two years, of which 67 articles with an impact factor of more than 20 were published, and 3 articles were published in the journals "Cell" and "Science" with the first signing unit.
At the same time, the award of scientific and technological achievements has maintained a good momentum. 21 achievements, including "The evolution of polyploidy homologous genes of cruciferous vegetables and the domestication of important horticultural traits", were declared for national science and technology awards; 28 achievements, including "Guangming No. 2 White Feather Broiler New Provenance Creation and Genome Breeding Technology System Construction", won provincial and ministerial awards, including 18 first prizes.
A number of major new products, new technologies and new equipment have been created. There are 88 new crop varieties approved by the state, 82 new crop varieties approved at the provincial level, 1 new livestock variety (series), and 6 new pesticides, new feeds, new veterinary drugs and other certificates. The creation of ARC microbial agent can promote the number of nodules and nitrogenase activity of soybean by 3 10 times, and increase the yield of soybean by more than 17%. Created the first genetically engineered biological pesticide "BT engineering bacteria" in China, which was selected as a major new product in agriculture and rural areas; Successfully developed the world's first avian influenza trivalent DNA vaccine, broke the foreign monopoly of the self-developed cat triple vaccine, and developed more than 100 million copies of brucellosis "gene deletion vaccine + differential diagnostic reagent"; The self-cultivated new varieties of Huaxi cattle accounted for 17 percent of the market in the past three years8%, the total market share of China and Singapore, China Animal White Feather Broiler Duck reached 40%, and the market share of domestic white feather broiler breeds increased to 251%, which strongly supports the independent and controllable core provenance of major livestock and poultry.
