蝴蝶翅膀的表型可塑性普遍存在，不同的翼型性状独立地进化出可塑性反应。蝴蝶的季节性可塑性是由激素蜕皮激素介导的。蜕皮激素信号已被证明影响其他昆虫的染色质景观。新的方法将使我们能够探索蜕皮激素介导的染色质重塑在蝴蝶季节性可塑性进化中的作用。蝴蝶对环境提示的表型可塑性是常见的，是蝴蝶翅膀模式多样性的主要驱动因素。内分泌信号蜕皮激素已被发现是蝴蝶可塑性的主要调节器。外部信号，如日长或温度，在内部转化为蜕皮激素滴度的变化，进而导致不同的表型，如季节性翅膀图案。在这里，我们回顾了由蜕皮激素介导的不同翅膀图案特征的可塑性，如翅膀颜色和眼点大小可以独立进化的证据。最近的研究表明，蜕皮激素通过染色质重塑机制调节果蝇基因表达。因此，我们认为蝴蝶对环境敏感的蜕皮激素滴度也可能通过染色质调节来促进不同的季节性表型。我们提出了一个结合了基因调控结构和生物体发育的蜕皮激素反应进化模型，并提出了一套可测试的机制假说，说明特定基因的可塑性反应谱如何进化。
HighlightsPhenotypic plasticity in butterfly wings is widespread, and different wing pattern traits evolve plastic responses independently.Seasonal plasticity in butterflies is mediated by the hormone ecdysone.Ecdysone signaling has been shown to affect the chromatin landscape in other insect species.New methods will enable us to explore the role of ecdysone-mediated chromatin remodeling in the evolution of seasonal plasticity in butterflies.Phenotypic plasticity in response to environmental cues is common in butterflies, and is a major driver of butterfly wing pattern diversity. The endocrine signal ecdysone has been revealed as a major modulator of plasticity in butterflies. External cues such as day length or temperature are translated internally into variation in ecdysone titers, which in turn lead to alternate phenotypes such as seasonal wing patterns. Here we review the evidence showing that ecdysone-mediated plasticity of different wing pattern features such as wing color and eyespot size can evolve independently. Recent studies show that ecdysone regulates gene expression in Drosophila melanogaster via a chromatin remodeling mechanism. We thus propose that environmentally responsive ecdysone titers in butterflies may also function via chromatin regulation to promote different seasonal phenotypes. We present a model of ecdysone response evolution that integrates both gene regulatory architecture and organismal development, and propose a set of testable mechanistic hypotheses for how plastic response profiles of specific genes can evolve.
