摘要:

鸡作为世界上分布最为广泛的家养动物之一,对不同环境具有良好的适应能力并形成了稳定的遗传机制,是研究动物环境适应性的重要模型。测序技术的成熟与全球环境数据库的日渐完善使遗传与环境的关联分析成为可能。群体遗传学、景观基因组学、泛基因组学等多种研究方法不断丰富鸡环境适应性的研究,鉴定出一系列与环境适应性相关的候选因子,如与低氧适应性相关的关键因子EPAS1、HIF1A;与鸡寒冷适应性相关的关键因子av-UCP;与鸡高温适应性相关的关键因子HSP,为动物环境适应性遗传机制研究奠定了重要基础。尽管如此,目前鸡环境适应性的分子机制仍不完善。本文从高海拔适应性、冷适应性、热适应性、干旱适应性及综合气候适应性等5个方面,概述近年来鸡的环境适应性研究进展,引出鸡环境适应性研究面临的问题,并对未来的研究趋势进行展望,以期为鸡的种质资源保护与利用提供理论支持。

Abstract:

Chicken is one of the most widely distributed animals in the world.It has evolved a stable genetic mechanism that allows it to adapt well to various environments, leading chicken as to become an important model for studying the biological mechanism of environmental adaptability. The development of sequencing technology and global environmental databases has made it possible to analyze the association between genetics and the environment. Population genetics, landscape genomics, pan-genome, and other research methods constantly promote researches on the chicken environmental adaptability, identifying a series of candidate factors, such as EPAS1 and HIF1A related to hypoxia adaptability; av-UCP related to cold adaptability and HSP related to heat adaptability in chickens, which laid the foundation for further studies on the genetic mechanism of environmental adaptability. Nevertheless, the molecular mechanisms of chicken environmental adaptability are still elusive. In this review, we summarize the recent research progress that chicken adapted to high-altitude, cold, heat, drought, and comprehensive climate, and put forward the challenges faced and the future research spots in the field, aiming to provide theoretical support for the conservation and utilization of chicken genetic resources.

Key words: chicken, environmental adaptability, omics, environmental variables
