RNA-seq data of healthy and fungal infected Tachypleus tridentatus embryos

The "living fossil" <i>Tachypleus tridentatus</i> holds significant medical and economic value but is currently experiencing a severe decline in germplasm resources. The extended incubation period of <i>T. tridentatus</i> eggs make them susceptible to invasion by pathogenic microorganisms, with fungal infections posing a major threat to embryonic development. However, the molecular immune mechanisms underlying embryonic immunity in <i>T. tridentatus</i> remain poorly understood. We collected <i>T. tridentatus</i> embryos at stages 18-20 that were naturally infected with <i>Aspergillus candidus</i> under aquaculture conditions, and conducted RNA sequencing to analyze transcriptomic response to the fungal infection.
