Bioinformatics was used to seek the homologous gene of EXT1 in Strongylocentrotus purpuratus which was just discovered and had the correlation to human hereditary multiple exostoses. The sequence, exons, coding protein, physical and chemical characters of EXT1 gene were analyzed. The structure and function of its coding protein were predicted, and the phylogenetic tree for the homologous gene was constructed, which provided certain basis for the future research of human EXT1 gene.

利用生物信息学方法寻找人类遗传多发性外生性骨疣EXT1基因在紫色球海胆中的同源基因，对该基因的序列、外显子信息、编码蛋白及其理化性质进行分析，并预测其编码蛋白的结构与功能，构建其同源基因的系统进化树，旨在为进一步研究人体EXT1基因提供一定的依据。

提出了一种新的基于自适应小波包变换的二叉树结构算法及它在宽带系统中的窄带干扰定位和弃除技术中的应用。

Separated cultures were isolated from 4 different koumiss examples, the complete 16SrRNA gene of these strains were sequenced, and phylogenetic trees were constructed. The isolateswere identified to the most related strain which had the highest affinity. The identified strains weresix L. lactis, five L. plantarum, five E. faecium, four E. faecalis, two L. casei, two L. helveticus, twoS. thermophilus, one L. delbrueckii subsp, bulgaricus, one Leu. mesenteroides, one Leu. garlicum.

本研究中从4份酸马奶中分离得到了29株乳酸菌，测定了这些乳酸菌的16S rRNA基因全长序列，并构建了乳酸菌属的系统发育树，根据亲缘关系对乳酸菌进行了鉴定，其中L.lactis(6株)，L.plantarum(5株)，E.faecium(5株)，E.faecalis(4株)，L.casei(2株)，L.helveticus(2株)，S.thermophilus(2株)，L.delbrueckii subsp.bulgaricus(1株)，Leu.mesenteroides(1株)，Leu.garlicum(1株)。

And the complete cDNA sequence of GSTR was 1002bp in length, containing a coding region of 678bp (encoding 225 amino acids). Results of the phylogenetic analysis revealed that the deduced amino acid sequence of the orange-spotted grouper was very similar to the GSTA of other fishes, such as common carp and zebrafish. The GSTR existed only in fish, but not in any other aquatic animals or land mammals (e.g. rat, mouse and human).

构建系统进化树发现，斜带石斑鱼与鲤鱼、斑马鱼GSTA氨基酸同源性较高，而GSTR为鱼类所特有并共同占据进化树上独立的分枝，与大鼠、小鼠、人等哺乳动物GST现有所有类型同源性均较低。
