In the present paper, the Sox gene expression analysis of different tissues from the Trionyx sinensis was studied by using RTPCR, and Sox gene fragments of expression from the testicle, brain and spleen were cloned using RTPCR products. The results show that Sox gene has specific expression in the testicle, brain, spleen, cardiac muscle and kindney and hasn't expression in muscle, liver and ovary. The results of clone reveal that the Sox genes of expression in the testicle are TSSox1 and TSSox 4, and those are TSSox2 and TSSox4 in the brain, and that is TSSox4 in the spleen. This suggests that the Sox gene act important role not only on the sex determination, but also on the development of neural system, immunocyte system and the differentiattion of male germ cell.

本文采用RT—PCR技术，研究了中华鳖不同组织Sox基因的表达，并通过PCR直接克隆法，分析了来自睾丸、脑和脾组织中的Sox基因序列结果表明在中华鳖的成体组织中，Sox基因在脑、心肌、肾、脾和雄性的睾丸组织中均有不同程度的表达，而在肌肉、肝脏和雌性的卵巢中则无表达，显示该基因具有组织表达特异性克隆分析显示，在睾丸组织中表达的是TSSox1和TSSox4基因，而在脑组织中表达的是TSSox2和TSSox4基因，脾组织中表达的是TSSox4基因此结果表明Sox基因不仅在性别决定中起作用，还可能在神经系统、免疫系统多种组织中起重要作用

To investigate the mechanism of wood formation and lignin biosynthesis, it is important to understand the function and characteristic of OMT. In the present study, a set of primer was designed based on the conserved region of OMT genes from several woody and non-woody plants, to clone the counter part gene by PCR and RACE from Chamaecvparis formosensis Matsum., Chamaeeyparis obtusa var. Jormosana, Abies kawakarnii, Tsuga ehinensis var. Jormosana and Taiwania eryptonierioide Hayata. The cloned genes were sequenced and their amino acid sequences predicted.

Chicken IL-15(ChIL-15), Which was discovered in 2001, plays a main role in activating NK cells and CD8+ memory T cells, and may therefore have potential as a vaccine adjuvant.According to published ChIL-15 gene sequence, a pair of primers were designed and synthesized to clone ChIL-15 cDNA from ConA-activated chicken splenocytes by RT-PCR. Recombinant plasmid pUC19ChIL-15 carrying the ChIL-15 gene was constructed. The gene encoding mature ChIL-15 (mChIL-15) was amplified from pUC19ChIL-15 by PCR and cloned into pMD 18-T vector. After digested with Kpn I /Pst I , the mChIL-15 gene was subcloned into prokaryotic expression vector pPRoEX橦Ta and transformed into E.coli DH5a .The transformant was induced by IPTG, and the recombinant ChIL-15(rChIL-15) was expressed as a fusion protein with a histidine hexamer tag at the N-terminal end of the protein. Following expression, the protein was purified by ProBond?Nickel-Chelating Resin. The uninduced and induced protein lysates and the purified protein were separated by SDS-PAGE and transferred onto nitrocellulose membrane to identify rChIL-15 by Western blot. The rChIL-15 was used to immune the guinea pig to obtain rChIL-15 polyclonal antibody.
