Abstract
Bombyx mori nucleopolyhedrovirus (BmNPV) is the most serious viral disease in silkworms. To investigate the mechanisms of the immune responses of B. mori to a BmNPV infection, a suitable reference gene (RG) is necessary for normalizing data when studying the expression of genes in BmNPV-infected silkworms or cells. Thus, quantitative real-time PCR polymerase chain reaction was used to compare the stability of expression of nine potential RGs, including the actin A3, translation initiation factor 3 (TIF-3), TIF-A4, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), 18S RNA, 28S RNA, TATA-binding protein (TBP), ribosomal protein L3 (Rpl3), and α-tubulin genes, in silkworms infected with BmNPV. The results were analyzed by BestKeeper, geNorm, and NormFinder software. Overall, α-tubulin exhibited the most stable gene expression in BmNPV-infected silkworms, and this was verified by western blotting of the α-tubulin protein. Moreover, we detected the expression of some genes involved in the immune signaling pathways of silkworms after BmNPV infection using α-tubulin as an internal RG.
