BACKGROUND Decapods are an order of crustaceans which includes shrimps, crabs, lobsters and crayfish. They occur worldwide and are of great scientific interest as well as being of ecological and economic importance in fisheries and aquaculture. However, our knowledge of their biology mainly comes from the group which is most closely related to crustaceans - insects. Here we produce a de novo transcriptome database, crustacean annotated transcriptome (CAT) database, spanning multiple tissues and the life stages of seven crustaceans. DESCRIPTION A total of 71 transcriptome assemblies from six decapod species and a stomatopod species, including the coral shrimp Stenopus hispidus, the cherry shrimp Neocaridina davidi, the redclaw crayfish Cherax quadricarinatus, the spiny lobster Panulirus ornatus, the red king crab Paralithodes camtschaticus, the coconut crab Birgus latro, and the zebra mantis shrimp Lysiosquillina maculata, were generated. Differential gene expression analyses within species were generated as a reference and included in a graphical user interface database at http://cat.sls.cuhk.edu.hk/. Users can carry out gene name searches and also access gene sequences based on a sequence query using the BLAST search function. CONCLUSIONS The data generated and deposited in this database offers a valuable resource for the further study of these crustaceans, as well as being of use in aquaculture development.

甲壳动物注释的转录组（CAT）数据库。

背景技术十足动物是甲壳类动物的一类，包括虾，蟹，龙虾和小龙虾。它们在世界范围内发生，具有极大的科学价值，在渔业和水产养殖中具有生态和经济意义。但是，我们对它们的生物学的了解主要来自与甲壳类最密切相关的物种-昆虫。在这里，我们产生了一个从头转录组数据库，一个甲壳纲注释的转录组（CAT）数据库，该数据库跨越了多个组织以及七个甲壳纲的生命阶段。描述来自六个十足动物和一个足脚动物的总共71个转录组装配体，包括珊瑚虾Stenopus hispidus，樱桃虾Neocaridina davidi，红爪小龙虾Cherax quadricarinatus，多刺龙虾Panulirus ornatus，红色帝王蟹Paralithodes camtschaticus，产生了椰子蟹Birgus latro和斑马螳螂虾Lysiosquillina maculata。物种内部的差异基因表达分析已作为参考，并包含在http://cat.sls.cuhk.edu.hk/的图形用户界面数据库中。用户可以进行基因名称搜索，也可以使用BLAST搜索功能根据序列查询访问基因序列。结论在该数据库中产生和储存的数据为进一步研究这些甲壳类动物以及在水产养殖发展中的使用提供了宝贵的资源。用户可以进行基因名称搜索，也可以使用BLAST搜索功能根据序列查询访问基因序列。结论在该数据库中产生和储存的数据为进一步研究这些甲壳类动物以及在水产养殖发展中的使用提供了宝贵的资源。用户可以执行基因名称搜索，还可以使用BLAST搜索功能根据序列查询访问基因序列。结论在该数据库中产生和储存的数据为进一步研究这些甲壳类动物以及在水产养殖发展中的使用提供了宝贵的资源。
