Seasonal adaptation in animals is a complex process that involves genetic, epigenetic, and environmental factors. The present review explores recent studies on epigenetic mechanisms implicated in seasonal adaptation in animals. The review is divided into three main sections, each focusing on a different epigenetic mechanism: DNA methylation, histone modifications, and non-coding RNA. Additionally, the review delves into the current understanding of how these epigenetic factors contribute to the regulation of circadian and seasonal cycles. Understanding these molecular mechanisms provides the first step in deciphering the complex interplay between genetics, epigenetics, and the environment in driving seasonal adaptation in animals. By exploring these mechanisms, a better understanding of how animals adapt to changing environmental conditions can be achieved.
动物的季节性适应是一个复杂的过程，涉及遗传、表观遗传和环境因素。本综述探讨了最近关于表观遗传机制在动物季节性适应中的作用的研究。本综述分为三个主要部分，分别关注不同的表观遗传机制：DNA 甲基化、组蛋白修饰和非编码 RNA。此外，本综述还深入探讨了目前对这些表观遗传因素如何调节昼夜节律和季节性周期的理解。了解这些分子机制是破译遗传、表观遗传和环境在驱动动物季节性适应中的复杂相互作用的第一步。通过探索这些机制，可以更好地了解动物如何适应不断变化的环境条件。
