Abstract

By using a low-resolution macrorestriction map as the foundation (R. Majumder et al., J. Bacteriol. 176:1105-1112, 1996), an ordered cloned DNA map of the 3.2-Mb chromosome of the hypertoxinogenic strain 569B of Vibrio cholerae has been constructed. A cosmid library the size of about 4,000 clones containing more than 120 Mb of V. cholerae genomic DNA (40-genome equivalent) was generated. By combining landmark analysis and chromosome walking, the cosmid clones were assembled into 13 contigs covering about 90% of the V. cholerae genome. A total of 92 cosmid clones were assigned to the genome and to regions defined by NotI, SfiI, and CeuI macrorestriction maps. Twenty-seven cloned genes, 9 rrn operons, and 10 copies of a repetitive DNA sequence (IS1004) have been positioned on the ordered cloned DNA map.

摘要

以低分辨率的宏观限制酶切图谱为基础(R. 马宗德等人,《细菌学杂志》176:1105 - 1112,1996年),构建了霍乱弧菌高毒素产生菌株569B 3.2兆碱基染色体的有序克隆DNA图谱。构建了一个约4000个克隆的黏粒文库,其中包含超过120兆碱基的霍乱弧菌基因组DNA(相当于40个基因组)。通过结合地标分析和染色体步移,将黏粒克隆组装成13个重叠群,覆盖了约90%的霍乱弧菌基因组。总共92个黏粒克隆被定位到基因组以及由NotI、SfiI和CeuI宏观限制酶切图谱定义的区域。27个克隆基因、9个rrn操纵子和10个重复DNA序列(IS1004)的拷贝已定位在有序克隆DNA图谱上。
