Hybrid yellow catfish (Tachysurus vachelli x Tachysurus fulvidraco) is one of the most important freshwater fish in China, intensive culturing has caused increased susceptibility to bacteria, viruses, and parasites. However, little is known about its adaptation mechanisms to pathogen infection. To better understand its immune system and immune related gene under pathogen infection, the transcriptome was analyzed by comparing the data of hybrid yellow catfish spleen stimulated by PGN and PBS. There were 285 Differentially Expressed Genes (DEGs) between PGN treated experimental groups and PBS control groups at 24h, including 213 up regulated and 72 down regulated DEGs. The expression of qRT-PCR from five up regulated DEGs and five down regulated DEGs were consistent with RNA-Seq. In the analysis of GO enrichment, DEGs in the spleens of PGN treated hybrid yellow catfish were significantly enriched in GO items, including biological process, cellular component, and molecular function items. The identified DEGs and enriched GO terms and KEGG pathways were useful for understanding the physical and biochemical performances, and the transcriptome data greatly enriched the genetic information of hybrid yellow catfish.
