甲壳动物亚门包括了许多具有重要的生态与经济价值的物种。随着对甲壳类动物水产品消耗的逐年递增，对甲壳动物的发育，生长与繁殖机制等方面的研究在水产、养殖、物种保育和生态保护等领域都有着重要的作用。在这些甲壳动物的生物过程中，转录因子对基因表达的调控起着非常重要的作用。然而，由于大多数甲壳动物尤其是具有重要的生态与经济价值的十足目基因组序列的缺乏，对这些物种的转录调控进行全面系统地研究变得极为困难。因此为了填补甲壳动物转录调控研究的空白，本项目拟产生并收集大量甲壳动物的转录组数据，鉴定91个甲壳类物种的转录组中的所有转录因子。通过多重生物信息学分析，本项目将研究转录因子在甲壳动物中的进化关系，推测其功能与转录调控网络在甲壳动物中的保守性与可变性，从而，为甲壳动物的研究者们提供丰富的信息，有助于研究甲壳动物各种生物过程中的转录调控机制。

Subphylum Crustacea includes species of major ecological and economic importance. Along with the increased consumption of crustacean seafood, understanding the regulatory mechanisms of growth, reproduction and development in crustaceans is vital to fisheries, aquaculture, biodiversity conservation and environmental protection. In these biological processes, transcription factors play an important role in regulating gene expression. However, due to the lack of genome sequence for most crustacean species, especially decapods of ecological and economic values, it is very difficult to study the transcriptional regulations of these species in a system-wide scale. Therefore, to fill the knowledge gap of transcriptional regulation study in crustaceans, this proposed study will generate and curate crustacean transcriptome data, and characterize the repertoire of transcription factors in 91 crustacean species. The evolution, functions and regulatory networks of crustacean transcription factors will be analyzed using a series of bioinformatics studies. The expected results will provide useful information for crustacean researchers to understand transcriptional regulatory mechanisms in crustacean biology.
