In this experiment, we screen the major protective antigen gene-SOD gene of M. paratuberculosisin order to study the sensitive, specific diagnostic reagent and prophylaxis preparation, especially theDNA vaccine. The SOD gene was amplified from Mycobacterium paratuberculosis C-2 chromosomalDNA by using the PCR technique and cloned into pMD18-T Vector System. We gained a SOD gene of624bp.The recombinant clone was identified byα-complementarity, enzyme digestion and PCRidentification. The result indicated that the recombinant plasmid pMD18-T-SOD was successfullyconstructed. Moreover, through sequential determination and DNASTAR analysis between the clonedSOD gene of M. paratuberculosis C-2 and that of the M.paratuberculosis K-10 strain, the sequentialhomogeneity reached 99%, and the amino acid homogeneity reached 99.5%. The preceding analysisindicated that the SOD gene was very conservative in M. paratuberculosis.

为了研制副结核病敏感、特异的诊断试剂和新型、高效的预防制剂，尤其是DNA疫苗，本研究筛选了M.paratuberculosis主要保护性抗原SOD基因，以M.paratuberculosis C-2染色体DNA为模板，以SOD基因的特异性引物进行PCR扩增，获得了624bp的SOD基因，通过T-A克隆技术，将PCR产物克隆至pMD18-T Vector中，以质粒大小、酶切分析、PCR扩增及序列分析鉴定重组克隆，成功地构建出克隆质粒pMD18-T-SOD，序列测定及DNASTAR分析表明，所获得的M.paratuberculosis C-2 SOD基因与Gen Bank中M.paratuberculosis K-10 SOD基因的大小完全一致，两者核苷酸序列的同源性为99％，氨基酸序列的同源性为99.5％，表明该基因在副结核分枝杆菌中是高度保守的。

For the first time, this paper presented the concepts about two basic deformations of Pascal's triangle, that is, Shifted Deformation and Clone Deformation.

本文首次提出了杨辉三角的两种基本变体的概念，即错位变体和克隆变体。

Segments of Adh gene in azuki bean (variety KS 5), covering an interval between partial intron 3 and intron 9, were amplified and sequenced with two pairs of primers. The result has proven the viability of using conserved sequences in a completely sequenced gene of one species to clone same gene in another species. In the comparison between Adh genes of azuki bean and pea, high sequence similarity (about 80%) in exon and long length difference (up to 116 bp) in intron were found. Besides, the edge regions of Adh introns with GT/AG counterparts and more conserved sequences than central regions was observed in both species.
