Abstract

Abstract: As one of the important livestock, the goat not only provide abundant materials for human beings, such as milk, meat and wool, but also have good adaptability to live in extreme environment such as heat, cold and drought areas. However, the molecular mechanism of environmental adaptability has not been fully explained in goats. With the development of sequencing technology and the rise of landscape genomics, genetic environment association analysis has been carried out in many studies, and a series of candidate genes related to environmental adaptability have been reported, which provided an important basis for analyzing the genetic mechanism of environmental adaptability in goats. This review introduces the methods of genetic environment association analysis from the perspective of landscape genomics, including classification test, logistic regression, general linear model and mixed-effect model. In view of the current situation of environmental adaptability in goats, the research progress in recent years was summarized from 5 aspects:high altitude adaptability, heat adaptability, cold adaptability, drought adaptability and comprehensive climate adaptability. Finally, this paper pointed out the existing problems in the study of environmental adaptability in goats, and prospected the future research trends, in order to provide a theoretical basis for collecting, protecting and utilizing the goat genetic resources.

Key words: environmental adaptability, goat, genetic variation, genetic environment association analysis
