Four hundred and sixty five randomly selected clones from a cDNA library of Blattella germanica were partially sequenced and searched using BLAST as a means of analyzing the transcribed sequences of its genome. A total of 363 expressed sequence tags (ESTs) were generated from 465 clones after editing and trimming the vector and ambiguous sequences. About 42% (154/363) of these clones showed significant homology with other data base registered genes. These new B. germanica genes constituted a broad range of transcripts distributed among ribosomal proteins, energy metabolism, allergens, proteases, protease inhibitors, enzymes, translation, cell signaling pathways, and proteins of unknown function. Eighty clones were not well-matched by database searches, and these represent new B. germanica-specific ESTs. Some genes which drew our attention are discussed. The information obtained increases our understanding of the B. germanica genome.
从德国小蠊的一个cDNA文库中随机挑选出465个克隆进行部分测序,并使用BLAST进行搜索,以此作为分析其基因组转录序列的一种手段。在编辑和修剪载体及模糊序列后,从465个克隆中总共获得了363个表达序列标签(EST)。这些克隆中约42%(154/363)与其他数据库中登记的基因显示出显著的同源性。这些新的德国小蠊基因构成了广泛的转录本,分布在核糖体蛋白、能量代谢、过敏原、蛋白酶、蛋白酶抑制剂、酶、翻译、细胞信号通路以及功能未知的蛋白质中。有80个克隆在数据库搜索中匹配度不佳,这些代表了新的德国小蠊特异性EST。文中讨论了一些引起我们注意的基因。所获得的信息增进了我们对德国小蠊基因组的了解。
