Like all organisms, members of the crustacean order Decapoda must coordinate their physiology and behavior to accommodate recurring patterns of environmental change. Genetically encoded biological clocks are responsible, at least in part, for the proper timing of these organism-environment patternings. While biological clocks cycling on a wide range of timescales have been identified, the circadian signaling system, which serves to coordinate physiological/behavioral events to the solar day, is perhaps the best known and most thoroughly investigated. While many circadian patterns of physiology/behavior have been documented in decapods, few data exist concerning the identity of circadian genes/proteins in members of this taxon. In fact, large collections of circadian genes/proteins have been described from just a handful of decapod species. Here, a publicly accessible transcriptome, produced from tissues that included the nervous system (brain and eyestalk ganglia), was used to identify the molecular components of a circadian signaling system for rock lobster, Jasus edwardsii, a member of the decapod infraorder Achelata. Complete sets of core clock (those involved in the establishment of the molecular feedback loop that allows for ~ 24-h cyclical timing), clock-associated (those involved in modulation of core clock output), and clock input pathway (those that allow for synchronization of the core clock to the solar day) genes/proteins are reported. This is the first description of a putative circadian signaling system from any member of the infraorder Achelata, and as such, expands the decapod taxa for which complete complements of putative circadian genes/proteins have been identified.

鉴定推定的Jasus edwardsii（甲壳纲；十足目； Achelata）昼夜节律信号系统的分子成分。

像所有生物一样，甲壳纲纲十足目的成员必须协调其生理和行为，以适应环境变化的反复发生。遗传编码的生物钟至少部分负责这些生物环境模式的正确时机。虽然已经确定了在各种时间尺度上循环的生物钟，但用于协调生理/行为事件到太阳日的生物钟信号系统也许是最著名和研究最彻底的。尽管十足动物已经记录了许多生理/行为的昼夜节律模式，但是关于该分类群成员中昼夜节律基因/蛋白质身份的数据很少。实际上，仅从少数十足动物中就已经描述了许多生物钟基因/蛋白质。这里，Jasus edwardsii，十足的亚足纲Achelata的成员。完整的核心时钟（与建立大约24小时循环定时的分子反馈回路有关的部分），与时钟相关的（与调制核心时钟输出有关的部分）和时钟输入路径（允许报告了核心时钟与太阳日的同步）基因/蛋白质。这是来自陆续无足动物的任何成员的假定的昼夜节律信号系统的第一个描述，因此，扩展了十足动物分类群，为此已确定了完整的假定的昼夜节律基因/蛋白质。
