It was then introduced by gene pulser into acrystalliferous strain CryB and a recombinant strain CryB (pBMBZGC10) was obtained. Different fermentative solutions of recombinant strain were used for multi-spray on leaves of Brassica pekinesis, Ipomoea aquatica and Lycopersicon esculentum.

Objective: The genes were connected basing on obtain gene of MCP and DAF of liver and fetal marrow of Chinese adult and then design mammiferous vector of the hMCP-DAF fusion gene. Finally transfer hMCP-DAF fusion gene to the early embryo of jinhua''s pig.

目的 在获得中国成人肝脏、胎儿骨髓MCP、DAF基因克隆的基础上，进一步将两个基因串接，并构建hMCP-DAF融合基因的哺乳动物表达载体，筛选出具表达活性的hMCP-DAF并导入金华猪早期胚胎。

Among all, deleted in liver cell (DLC-1) gene was found to play an important role in hepatoma in 1998, and after that hypermethylation on the promoter of the DLC-1 gene was found in many other cancers, suggesting that epigenetic modification is another way to control the carcinogenesis. Another gene, Endothelin type B receptor, was found to cause megacolon syndrome by accident while searching the cause of white spot in mouse, and was also found hypermethylation on its promoter in some cancer cells.

在此中，DLC-1基因自从1998年后被发现在肝癌的演化上扮演重要的角色后，在许多其他的癌症上也发现此基因上位於promoter的CpG islands有过度甲基化的现象，推论DLC-1基因的过度甲基化是一种经由epigenetic modification调节细胞癌化的方式。

The result indicates that there are one dominant and one recessive complementary gene that are effective against the Indian race 2E16. However, the monosomic analysis results indicated there was one resistant gene to the Indian race 2E16 and the gene was located on chromosome 3B. The current study shows that it is different from the known genes.

采用常规杂交分析方法，对铭贤169与阿夫杂交的F_1、F_2、BC_1代及其亲本进行抗性鉴定和统计分析，结果表明，阿夫对2E16菌系的抗性至少由1对显性抗条锈基因控制；通过单体分析将阿夫抗2E16菌系的1对显性基因定位在3B染色体上，等位性分析表明该基因不同于目前的已知基因。

The Sry gene sequence of Muntiacus crinifrons was acquired and the conclution was that there are 83% homology between the human and Muntiacus crinifrons. It was testified that in all mammal Sry gene is consertive. On the other side the Sry gene was located to the Y2 chromosome of the Muntiacus crinifrons.

They all contain 13 protein coding gene,2 rRNA gene,22 tRNA gene and 1 D-Loop.The base composition for the four nucleotides is A-32.0%,C-27.6%,G-14.7%,T-25.8%,And it is A-32.5%,C-26.9%,G-14.1%,T-26.5%for Yellow-throated Marten.But there are some definite differences in base composition,the using of Initiation codon and Stop codon,and the mode of repeat sequences in control region.The codon usages of Manes have bias,and the ttiird locations of codon of protein-coding genes have the higher frequency in using A and C.There may be some relativity with the content of A and C in D-loop,namely,it has relation with the mode of repeat sequences.The complete mitochondrial genome of the Sable and Yellow-throated Marten were submitted to GenBank,and the accession number are FJ429093 and FJ719367 respectively.3、The complete mitochondrial genome of 6 other species of Mustelidae from GenBank and some sequences of D-loop from the 6 species were aligned.
