Abstract: The yak is widely distributed in the plateau area with an altitude of 3000-5000 m, and is an important animal species for the development of the local animal husbandry economy. After a long-term adaptive evolution, the yak showed high-altitude adaptation characteristics in terms of physiological structure and genetic molecules. With the wide application of omics technology, the plateau adaptation mechanism of the yak has been further revealed. In this paper, the physiological structure and molecular mechanism of lung and heart in high altitude hypoxia adaptation, the periodic regulation of coat and the molecular mechanism of fat deposition and metabolism in cold adaptation, the molecular basis of disease resistance, the physiological basis and molecular mechanism of reproduction in the yak were reviewed and outlook based on relevant reports at home and abroad.

Key words: yak, high altitude adaptation, hypoxia, paramos, disease resistance, reproduction
