视色素被称为视蛋白，是动物颜色视觉的主要分子基础。昆虫是最多样化的动物群体之一，它们的视觉系统反映了各种生活史。果蝇中昆虫视蛋白的研究导致了神经科学、发育和进化领域的重大进展。在过去的25年里，D. melanogaster的研究提高了我们对视蛋白基因型-表型关系的理解，而在其他昆虫中的比较工作则通过基因复制、共表达和同源转换扩展了我们对昆虫眼睛进化的理解。即便如此，直到最近，技术和采样限制了我们对进化用于塑造昆虫眼睛多样性的基本机制的理解。随着基因组编辑和体外表达测定的出现，昆虫视蛋白的研究有望揭示进化生物学、视觉神经科学和动物行为学的新前沿。这篇文章是主题问题的一部分“理解色觉：分子，生理，神经元和行为研究节肢动物”。
The visual pigments known as opsins are the primary molecular basis for colour vision in animals. Insects are among the most diverse of animal groups and their visual systems reflect a variety of life histories. The study of insect opsins in the fruit fly Drosophila melanogaster has led to major advances in the fields of neuroscience, development and evolution. In the last 25 years, research in D. melanogaster has improved our understanding of opsin genotype–phenotype relationships while comparative work in other insects has expanded our understanding of the evolution of insect eyes via gene duplication, coexpression and homologue switching. Even so, until recently, technology and sampling have limited our understanding of the fundamental mechanisms that evolution uses to shape the diversity of insect eyes. With the advent of genome editing and in vitro expression assays, the study of insect opsins is poised to reveal new frontiers in evolutionary biology, visual neuroscience, and animal behaviour. This article is part of the theme issue ‘Understanding colour vision: molecular, physiological, neuronal and behavioural studies in arthropods’.
