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

The “living fossil” Tachypleus tridentatus holds significant medical and economic value but is currently experiencing a severe decline in germplasm resources. The extended incubation period of T. tridentatus 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 T. tridentatus remain poorly understood. We collected T. tridentatus embryos at stages 18-20 that were naturally infected with Aspergillus candidus under aquaculture conditions, and conducted RNA sequencing to analyze transcriptomic response to the fungal infection.
