Abstract:

【Objective】The objective of this study is to clone the target of rapamycin gene (TOR) of Apolygus lucorum (AlTOR), analyze the expression profile of AlTOR as well as its expression patterns after injection of 20-hydroxyecdysone (20E) and its inhibitor U73122, obtain the recombinant protein and antibody against AlTOR protein, and to lay the foundation for the further study of AlTOR protein function.【Method】The full-length of AlTOR was cloned by RACE method. Using qRT-PCR technique, the expression pattern of AlTOR was determined at different developmental stages and different tissues in A. lucorum, as well as its expression patterns after injection of 20E and U73122. To construct its prokaryotic expression pCzn1-AlTOR, T vector containing the target gene was digested with the restriction enzyme EcoR I and Xho I and subcloned. The recombinant plasmid containing target gene was specifically expressed after induction by IPTG. The target recombinant protein has over expressed and has been purified by using Ni-NTA agarose. The polyclonal antibody was obtained by rabbit immunity, cell fusion and ascites preparation, and Western blot was used to detect the specificity of antibody.【Result】The open reading frame of AlTOR encodes 435 amino acids. AlTOR protein has the typical domains including the SIN1 domain, highly conserved CRIM domain and PH domain. qRT-PCR results showed that AlTOR was expressed in 1-day-old to 16-day-old of A. lucorum, in which the expression level was the highest at 1-day-old. AlTOR was expressed in all tissues of A. lucorum female adults, and the fat body had the highest expression level. 20E could induce the expression of AlTOR at different day-old nymphs, and could also induce the up-regulated expression of AlTOR in the head, wing, ovary and fat body of the female adults, which was increased by 200.00%, 118.89%, 20.53% and 60.82%, respectively, while U73122 significantly suppressed AlTOR expression in the midgut and ovary. The vector containing AlTOR was digested and linked to the vector pCzn1. The recombinant plasmid pCzn1-AlTOR expressed the target recombinant protein of 36 kD after induction by IPTG. The 36 kD target protein from the strain containing AlTOR was obtained by the Ni-NTA agarose and used as the antigen, and one cell line polyclonal antibody could specifically bind to the AlTOR recombinant protein and the total protein of the 3rd instar nymph of A. lucorum, indicating that the prepared AlTOR polyclonal antibody has good specificity.【Conclusion】The expression of AlTOR shows the developmental stage- and tissue-specificity. After the induction of 20E and its inhibitor, AlTOR shows the opposite responses. The obtained polyclonal antibody against AlTOR recombinant protein is highly specific.
