Abstract

Understanding the molecular basis of nocturnal and diurnal behaviors is crucial to uncovering adaptive specialization. Here, we employed the black cutworm (Agrotis ipsilon, BCW) to examine the rhythmic gene repertoire in nocturnal species. Daily eclosion patterns confirmed BCW’s nocturnal behavior. We generated daily transcriptomes for BCW and compared them with those of the diurnal monarch butterfly (Danaus plexippus). Both species share a core set of genes with rhythmic expression, indicating a fundamental timekeeping mechanism in Lepidoptera. Notably, metabolism-related genes exhibited significant phase shifts between BCW and the monarch butterfly, suggesting that metabolic differences underpin their contrasting behaviors. Additionally, while phototransduction genes in monarch butterflies show marginal rhythmicity, in BCW these genes are governed by light sensitivity rather than circadian regulation. This study provides molecular insights into the diversification of behavioral traits between diurnal and nocturnal insects.

鳞翅目动物昼夜节律差异的分子基础

了解夜间和日间行为的分子基础对于揭示适应性专业化至关重要。在这里，我们使用黑蛾（Agrotis ipsilon， BCW）来研究夜间活动物种的节律基因库。每天的羽化模式证实了BCW的夜间行为。我们生成了BCW的日转录组，并将其与日活动帝王蝶（Danaus plexippus）的日转录组进行了比较。这两个物种共享一组具有节律性表达的核心基因，表明鳞翅目中存在一种基本的计时机制。值得注意的是，代谢相关基因在白斑蝶和黑脉金斑蝶之间表现出明显的相移，这表明代谢差异是它们不同行为的基础。此外，虽然帝王蝶的光导基因表现出边际节律性，但在BCW中，这些基因受光敏感性而不是昼夜节律调节的支配。这项研究为研究昼行性昆虫和夜行性昆虫行为特征的多样性提供了分子视角。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
