Abstract
We generated RNA-seq data for the water flea Daphnia mitsukuri at five
developmental stages, including the embryo and representative
post-embryonic stages in the life cycle. Embryos showed a large number
of unique and highly expressed genes, mainly related to DNA replication,
differentiation, morphogenesis and the Hippo signaling pathway.
Post-embryonic stages showed an enrichment of transcripts for genes
involved in chemosensory perception, visual perception, cuticle
formation and antioxidative defense. These specific highly expressed
transcripts at post-embryonic stages are essential to help Daphnia to
respond to current or likely environmental stresses. Our data provide a
high-resolution view of transcriptome dynamics throughout development of
Daphnia, a model organism for ecology and evolution.
