Agrobacterium: From Biology to Biotechnology

Agrobacterium is a plant pathogen which causes the crown-gall disease, a neoplastic growth that results from the transfer of a well-defined DNA segment (transferred DNA, or T-DNA) from the bacterial Ti (tumor-inducing) plasmid to the host cell, its integration into the host genome, and the expression of oncogenes contained on the T-DNA. The molecular machinery, needed for T-DNA generation and transport into the host cell and encoded by a series of chromosomal (chv) and Ti-plasmid virulence (vir) genes, has been the subject of numerous studies over the past several decades. Today, Agrobacterium is the tool of choice for plant genetic engineering with an ever expanding host range that includes many commercially important crops, flowers, and tree species. Furthermore, its recent application for the genetic transformation of non-plant species, from yeast to cultivated mushrooms and even to human cells, promises this bacterium a unique place in the future of biotechnological applications.

The book is a comprehensive volume describing Agrobacterium's biology, interactions with host species, and uses for genetic engineering.

The only complete overview of all aspects of agrobacterium in the plant sciences Deals with various aspects of the biology of the diseases caused by agrobacterium Covers the basics of the bacteria itself, the mapping of its genome, through to its use in plant transformation and biotechnology Delves into the questions of ethics and law in the biotechnological applications of Agrobacterium

Klappentext

Agrobacterium is the only cellular organism on Earth that is naturally capable of transferring genetic material between the kingdoms of life, from prokaryotes to eukaryotes. Studies have uncovered a wealth of information on the process of Agrobacterium-mediated genetic transformation and on the bacterial and host cell factors involved in the infection. Agrobacterium has been shown to genetically transform, under laboratory conditions a large number of plant species and numerous non-plant organisms, indicating the truly basic nature of the transformation process. It is therefore not surprising that Agrobacterium and the genetic transformation itself have also become the focus of numerous ethical and legal debates.

'Agrobacterium' is a comprehensive book on Agrobacterium research, including its history, application, basic biology discoveries, and effects on human society. 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 readersincluding scientists and students involved in plant genetic engineeringwill find useful as a reference source for all major aspects of the Agrobacterium-mediated genetic transformation of plant and non-plant organisms.
