Major breakthrough! The Yangtze River Fisheries Research Institute published the first high-quality chromosomal atlas of spoon sturgeon

Chutian Metropolis Daily, January 13 (reporter Zhang Jianlin) Recently, the reporter learned from the Yangtze River Fisheries Research Institute that the research paper "The American paddlefish genome provides novel insights into chromosomal evolution and bone" led by the Yangtze River Fisheries Research Institute of the Chinese Academy of Fishery Sciences and cooperated by the Shenzhen Huada Oceanographic Research Institute and other units mineralization in early vertebrates.” "The Spoon Sturgeon Genome Opens Up New Horizons for Chromosomal Evolution and Bone Mineralization in Early Vertebrates" was published online by the internationally renowned academic journal Molecular Evolutionary Biology.

The research results successfully analyzed the whole genome sequence of the representative species of spoon sturgeon for the first time, constructed the first high-quality chromosome map of spoon sturgeon, revealed the chromosomal evolution mechanism unique to complex polyploid sturgeon, and analyzed the key bone mineralization process of early vertebrates, opening up a new perspective for the evolutionary research of early vertebrates.

Spoon-sturgeon, also known as American spoon-kissed sturgeon, is the spoon-kissed sturgeon of the Mississippi River, and lives in the slow-moving waters of the Mississippi River. They are closely related to sturgeon, which is one of the only two species of two genera left in the world, and the other is the white sturgeon that lives in the Yangtze River of China, which is nearly extinct.

The Endangered Fish Conservation Discipline Group of the Yangtze River Institute has long been committed to the conservation and genetic research of rare and endangered species such as Chinese sturgeon and Yangtze River sturgeon, which is another important breakthrough in the field of sturgeon research after the team collaborated in 2019 to publish the world's first sturgeon - small body sturgeon genome research.

It is understood that Cheng Peilin, assistant researcher of the Yangtze River Institute, Dr. Huang Yu of the Shenzhen Huada Institute of Oceanography, and Dr. Lu Yunyun of Neijiang Normal University are the co-first authors of the paper. Professor Shi Qiong, a researcher at the Yangtze River Institute and president of the Shenzhen Huada Institute of Oceanography, is the co-corresponding author of the paper. The research work has been jointly funded by the National Natural Science Foundation of China, the National Key Basic Research and Development Program (973 Program), the Ministry of Agriculture's Agricultural Public Welfare Industry Scientific Research Project, the International Cooperation Project of the Chinese Academy of Fishery Sciences, and the Basic Scientific Research Business Fund of the Yangtze River Institute.
