Transcriptomics studies are more likely to achieve predictive results when they rely on tissue- and cell-specific transcriptional data. Identification of cell types in novel model organisms by their transcriptional profiles is difficult without data on transcriptional differences among major tissues and anatomical features. Here we report the first dataset on tissue- and organ-specific transcriptomics in freshwater plankton crustacean Daphnia magna, reporting markers of eggs, hemocytes, gut, carapace, antennae and head (as well as the remaining carcass). Overall design: RNAseq of RNA tissue extracts from Daphnia eggs, hemocytes, guts, antennae, heads, carapace and carcass.
