Insects can adapt quickly and effectively to rapid environmental change and maintain long-term adaptations, but the genetic mechanisms underlying this response are not fully understood. In this review, we summarize studies on the potential impact of chromosomal inversion polymorphisms on insect evolution at different spatial and temporal scales, ranging from long-term evolutionary stability to rapid emergence in response to emerging biotic and abiotic factors. The study of inversions has recently been advanced by comparative, population, and 3D genomics methods. The impact of inversions on insect genome evolution can be profound, including increased gene order rearrangements on sex chromosomes, accumulation of transposable elements, and facilitation of genome divergence. Understanding these processes provides critical insights into the evolutionary mechanisms shaping insect diversity.
昆虫能够快速有效地适应快速的环境变化，并保持长期的适应能力，但这种反应的遗传机制还不完全清楚。在这篇综述中，我们总结了染色体倒位多态性对不同时空尺度昆虫进化的潜在影响的研究，从长期进化稳定性到对新兴生物和非生物因素的快速出现的反应。近年来，比较、群体和 3D 基因组学方法推动了对倒位的研究。倒位对昆虫基因组进化的影响可能是深远的，包括增加性染色体上的基因顺序重排、转座元件的积累以及促进基因组分化。了解这些过程为塑造昆虫多样性的进化机制提供了关键的见解。
