Abstract
Labeled Ti plasmid DNAs from diverse Agrobacterium strains were hybridized to Southern blots of pTi-B6-806 plasmid DNA digest fragments of known map order. The map location of DNA sequences common to all Ti plasmids was found to be extensive, consistent with the view that Ti plasmids have evolved from a common ancestral plasmid.
摘要
来自不同土壤杆菌菌株的标记Ti质粒DNA与已知图谱顺序的pTi-B6-806质粒DNA消化片段的Southern杂交印迹进行杂交。发现所有Ti质粒共有的DNA序列的图谱位置广泛，这与Ti质粒是从共同的祖先质粒进化而来的观点一致。
