The chromosomal DNA of Agrobacterium tumefaciens contains the genes required for bacterial attachment to plant cell which is an essential atage in crown gall tumorigenesis by Ti-plasmid. In order to clone the genes, Agrobacterium tumefaciens strain A5512 was mutagenized by transposon Tn5 and two Agrobacterium tumefaciens mutants which are attachment-defective and nontumorigenic were isolated. From one of the two mutants, a chromosomal virulence region which was required for attachment to the plant cells was cloned.
