像所有生物一样，甲壳纲十足目的成员必须协调他们的生理和行为，以适应环境变化的重复模式。基因编码的生物钟至少在一定程度上负责这些生物体-环境模式的正确计时。虽然生物钟在广泛的时间尺度上循环已经被确定，但昼夜节律信号系统（用于协调生理/行为事件到太阳日）可能是最知名和最彻底的研究。虽然许多生理/行为的昼夜节律模式已被记录在十足目动物中，但很少有数据存在关于该分类群成员的昼夜节律基因/蛋白质的身份。在这里，一个公开访问的转录组，从包括神经系统（大脑和眼柄神经节）的组织中产生，用于识别岩龙虾，Jasus edwardsii，十足目下目Achelata的成员的昼夜信号系统的分子组成。完整的核心时钟（那些参与建立的分子反馈回路，允许~ 24小时的周期性计时），时钟相关（那些参与核心时钟输出的调制）和时钟输入途径（那些允许核心时钟同步到太阳日）基因/蛋白质的报告。这是第一次描述一个假定的昼夜节律信号系统从任何成员的下目Achelata，因此，扩展十足类类群的完整互补的假定的昼夜节律基因/蛋白质已被确定。
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.
