Antibiotic resistance markers inserted adjacent to different cloned genes from Streptococcus mutans were used to determine the relative positions of these genes on the chromosome. The results showed that these genes, fru-1 and gbp, are closely linked to the gtfA-ftf-scrB cluster. However, gtfD was linked neither to this cluster nor to gtfB-gtfC.
将插入到变形链球菌不同克隆基因附近的抗生素抗性标记用于确定这些基因在染色体上的相对位置。结果表明,fru-1和gbp这些基因与gtfA-ftf-scrB基因簇紧密相连。然而,gtfD既不与该基因簇相连,也不与gtfB-gtfC相连。
