Mobilization of Chromosomes and Nonconjugative Plasmids by Cointegrative Mechanisms,e plasmids transfer themselves. Furthermore, in many cases they can also transfer (mobilize) chromosomal DNA or nonconjugative plasmids. Thus, mobilization, as we define it, is the process by which a conjugative plasmid accomplishes the transfer of DNA that is not self-transmissible.

Conjugative Pili and Pilus-Specific Phages,d in Germany (104, 135). In 1964, Crawford and Gesteland (61) observed the R17 phage (163) attached to the sex hair of the F. cell, a filamentous appendage that was named, more decorously, the F pilus by Brinton and shown to be genetically determined by the fertility factor F of ..

,-Mediated Transfer and Stable Incorporation of Foreign Genes in Plants,transfer to plants is the classic example of such a phenomenon. The genes required for this transfer are located on a 200-kbp Ti plasmid. As illustrated in Figure 9.1, a specific sector (the T-DNA) of the Ti plasmid is the element transferred. The 25-kbp T-DNA is bordered by 23-bp directly repeated
