Abstract:According to the gene sequences, the lectins in the genome of Chinese shrimp Fenneropenaeus chinensis, could be assorted into seven kinds of genes. In order to explore the expression differences among the seven lectins after WSSV challenge, real-time quantitative PCR was used to detect the expression profiles of these lectins at different time after WSSV challenge in Chinese shrimp. The results showed that, of the seven lectins, LT1(DQ167572.1), LT2(EU834289.1), LT3(EU834292.1) and LT5(EU834290.1) displayed hepatopancreas-specific expression profiles, and were WSSV-induced genes, while the other genes were mainly expressed in gills, intestines and muscles, and were non-WSSV-induced genes. The expression profiles of seven detected genes at different time after WSSV challenge were different with each other. Additionally, the analysis of variance (ANOVA) indicated that no significant difference was found at the expression level of seven lectins in gills, intestines and muscles, except hepatopancreases. These results showed that the biology function of the seven lectins were different from each other in Chinese shrimp F. chinensis.
