The evolutionary trees of SARS - CoV and SARS - like CoV were made up by using the Brede virus as outgroup, and analyzed variation in single nucleotide sequence.

结果：发现两次SARS自然流行的病毒可分为两个明显不同的聚类；第二次流行时从人类中分离的SARS冠状病毒和从果子狸等动物中分离的SARS样冠状病毒可分为两个基因型，两型的主要鉴别依据是病毒的全基因组变异而非Spike基因序列。

We designed primers according to the sequence of Genbank from Bifidobacterium breve and have cloned the putative isomerasekey gene and several fragments from the genome DNA of Lactobacillus acidophilus .

根据Genbank中短小双歧杆菌中可能的共轭化酶的序列资料，设计引物，克隆了可能的基因及几个片段并测序，其基因功能有待进一步验证。

Results The ISR sequence of Bifidobacterium longum containing 568 bp,was the same as Bifidobacterium breve and they were different from Bifidobacterium adolescentis and Bifidobacterium infantis which were only 510 bp.

结果长双歧杆菌和短双歧杆菌16S~23S rDNA ISR序列一致，全长568个碱基对；青春双歧杆菌与婴儿双歧杆菌序列一致，全长510个碱基对。

To investigate variation of soil bacteria community in response to the change in the above-ground vegetation, soil samples were collected at three sites, i.e. bamboo groves, mixture of bamboo and broadleaf tree and broadleaf forest. To explore variation of the soil bacterial structure, 16S-rDNA-V3-fragment-base DGGE (denaturing gradient gel electrophoresis) and clone sequence BLAST technologies were applied.

为了解毛竹人侵天然林后地下土壤微生物多样性的变化，分别采集了毛竹纯林、竹阔混交林和原始天然阔叶林下的土壤样品，应用建立于165 rDNA V3区片段的变性梯度凝胶电泳和克隆测序比对来研究土壤细菌结构的变化。

Exploring novel genes and gene combinations are of primary importance in plant drought-tolerance and water-saving research. Based on the EST sequence of MYB gene obtained in the research on molecular basis of drought-tolerance and water-saving in broomcorn millet Panicum miliaceum L.

根据在糜子抗旱节水分子基础研究中获得的一个糜子 MYB 基因的EST序列，以其序列及水稻MYB18基因的序列为基础设计引物，扩增得到1 739 bp的全长基因组序列。

PmMYB is a typical R2, R3-MYB transcription factor with its 2 typical DNA-binding domains (amino acid sites of 13-63 and 66-114).The multiple alignment of R2, R3 amino acid repeat regions of MYB genes among broomcorn millet, rice, corn, loblolly pine, Arabidopsis, capsicum, upland cotton, barley and aubergine indicates that R2, R3 repeat regions are very conserved. The phylogenetic analysis based on amino acid sequence shows that MYB genes are highly divergent with similarity ranging from 32% to 84%.

对其与水稻、玉米、火炬松、拟南芥、辣椒、陆地棉、大麦及茄子等9种植物的 MYB 基因的R2、R3重复区的氨基酸序列多重比较，表明R2R3重复序列在植物中具有较高的保守性；基于氨基酸序列的编码区系统进化树分析表明，不同植物的MYB基因遗传分化很大，序列相似性为32%~84%，其中糜子 MYB 基因与水稻的 MYB18相似程度最高(84%)，与大麦和玉米的相似性分别为46%和41%。
