倍半萜类化合物如保幼激素（JH）在昆虫和甲壳类动物中的生理重要性已被认识到。然而，人们对这两个密切相关的节肢动物群体何时以及如何获得JH信号系统知之甚少。金合欢酸甲酯（MF）是昆虫JH的天然前体，已被鉴定为甲壳动物的先天JH。然而，甲壳类动物中MF下游的接收和分子信号传导比昆虫中的JH信号传导少得多，其中耐甲氧普仑（Met）蛋白已被表征为JH受体。最近的一项研究表明，水蚤Met对MF的反应方式与昆虫Met对JH的反应方式相同，这表明JH受体在昆虫和甲壳类动物之间是保守的。为了了解JH信号的起源和进化，需要进一步的研究，扩展到更多的祖先节肢动物。
Physiological importance of sesquiterpenoids such as the juvenile hormone (JH) has been recognized in both insects and crustaceans. Yet, little is known about when and how these two closely related arthropod groups acquired the JH signaling system. Methyl farnesoate (MF), a natural precursor of insect JH, has been identified as an innate JH of crustaceans. However, the reception and molecular signaling downstream of MF in crustaceans is much less explored than JH signaling is in insects, where the Methoprene-tolerant (Met) protein has been characterized as a JH receptor. A recent study has shown that Daphnia Met responds to MF in a way insect Met responds to JH, suggesting that JH reception is conserved between insects and crustaceans. To understand the origin and evolution of JH signaling, further studies, extended to more ancestral arthropods, are needed.
