| Zusammenfassung: | "Agrobacterium is a comprehensive book on Agrobacterium research, including its history, application, and basic biology discoveries. Although the book largely focuses on providing a detailed review of virtually all molecular events of the genetic transformation process, it also provides coverage of ethical and legal issues relevant to the use of Agrobacterium as a "genetic transformation machine." The result is an all-inclusive text which readers - including scientists and students involved in plant genetic engineering - will find useful as a reference source for all major aspects of the Agrobacterium-mediated genetic transformation of plant and non-plant organisms."--BOOK JACKET. |
