简介：为了学习简历，活跃代谢物由导出海绵的未耕作的共生者生产了，海绵Gelliodesgracilis的共生者的一个metagenomicDNA图书馆被构造。DNA的平均尺寸在图书馆插入是20kb。这个图书馆用纸圆盘assaying为抗菌素活动被屏蔽。二克隆对小球菌tetragenus显示了抗菌剂活动。这二克隆的代谢物通过HPLC被分析。结果证明他们的代谢物与主人E的那些相当不同。包含向量pHZ132的关口iDH5α和主人。这研究可以介绍一条新途径给探索简历海绵共生者的活跃代谢物。

简介：表示顺序标注的Porphyrayezoensis(EST)的genomic资源被利用识别简单顺序重复(SSR)，或微卫星。这个方法拿了为基因身份的建立或为高多型性的获得使用EST和微卫星的优点。当基因标记whenmicrosatellites被附在基因，微卫星能被使用。由生物信息学分析揭示了，1162从21954颗ESTscontained微卫星和聚合分析显示984这些EST掉进112contigs，当另外的178EST是单条时。290唯一的包含SSR基因的一个总数被识别。AACSSR是微卫星的最人口多的类型。在所有微卫星之中占优势的GC富有的microsatelliteswere。
