In octopine-type A. tumefaciens R10, transfer of chromosomal arginine degradation genes (arc genes) was observed under conditions in which Ti plasmid transfer took place. However, transconjugants that had acquired the arc genes but not the Ti plasmid were recovered. During this process, several other chromosomal genes, such as genes encoding phage resistances or genes complementing a galactose utilization mutation or a glycine-serine auxotrophy, were transferred from strain R10 to the recipient.
在章鱼碱型根癌土壤杆菌R10中,在Ti质粒发生转移的条件下观察到染色体精氨酸降解基因(arc基因)的转移。然而,回收了获得arc基因但未获得Ti质粒的转接合子。在此过程中,其他几个染色体基因,如编码噬菌体抗性的基因或补充半乳糖利用突变或甘氨酸 - 丝氨酸营养缺陷型的基因,从菌株R10转移到了受体中。
