Book Description
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.

Book Description
This volume reviews various facets of Agrobacterium biology, from modern aspects of taxonomy and bacterial ecology to pathogenesis, bacterial cell biology, plant and fungal transformation, natural transgenics, and biotechnology. Agrobacterium-mediated transformation is the most extensively utilized platform for generating transgenic plants, but modern biotechnology applications derive from more than 40 years of intensive basic scientific research. Many of the biological principles established by this research have served as models for other bacteria, including human and animal pathogens. Written by leading experts and highlighting recent advances, this volume serves both as an introduction to Agrobacterium biology for students as well as a more comprehensive text for research scientists.

Book Description
The broad host range pathogenic bacterium Agrobacterium tumefaciens has been widely studied as a model system to understand horizontal gene flow, secretion of effector proteins into host cells, and plant-pathogen interactions. Agrobacterium-mediated plant transformation also is the major method for generating transgenic plants for research and biotechnology purposes. Agrobacterium species have the natural ability to conduct interkingdom genetic transfer from bacteria to eukaryotes, including most plant species, yeast, fungi, and even animal cells. In nature, A. tumefaciens causes crown gall disease resulting from expression in plants of auxin and cytokinin biosynthesis genes encoded by the transferred (T-) DNA. Gene transfer from A. tumefaciens to host cells requires virulence (vir) genes that reside on the resident tumor-inducing (Ti) plasmid. In addition to T-DNA, several Virulence (Vir) effector proteins are also translocated to host cells through a bacterial type IV secretion system. These proteins aid in T-DNA trafficking through the host cell cytoplasm, nuclear targeting, and T-DNA integration. Genes within native T-DNAs can be replaced by any gene of interest, making Agrobacterium species important tools for plant research and genetic engineering. In this research topic, we provided updated information on several important areas of Agrobacterium biology and its use for biotechnology purposes.

Book Description
This anthology traces the fascinating progress from plant pathology to biotechnology through 38 scientific papers on Agrobacterium, published over the past century. Included are the seminal scientific papers on the biology and application of Agrobacterium with introductory commentaries mostly by those involved in the original work. The commentaries give background to the papers and explain the problems faced and the techniques used, providing insight into the way fundamental research progresses.Agrobacterium tumefaciens has played a major role in the astounding advances that have been made over the past several decades in the areas of plant genetics, plant molecular biology, and plant genetic engineering. The papers included in this book were integral to the current understanding of the interaction of Agrobacterium with its hosts, its development into a major player in the genetic engineering of plants, and the biological control of crown gall.Agrobacterium tumefaciens: From Plant Pathology to Biotechnology is divided into five sections. The first section begins with 1904 when Erwin F. Smith began detailed work on crown gall and considered it to be a plant pathological problem. It explores many of the biological discoveries made over the past century, including the pivotal moment when Armin C. Braun discovered that crown gall was a plant cancer. Other papers cover the beginnings of T-DNA research and the development of vectors to improve the process of transferring T-DNA from bacterium to plant cell. The second section delves further into vector systems and genetic coding for disease and insect resistance, exploring the evolution of genetic engineering in crops.The final three sections deal with themes developed from crown gall studies, including ?quorum sensing? or population density, the DNA sequencing of one strain of A. tumefaciens, and the first genetically engineered organism, strain K1026, released for commercial use.According to Editor, Eugene Nester, ?This book should serve as a testimony to the 100 years of research on this remarkable organism, as well as to an international group of investigators who helped reveal secrets of this natural genetic engineer.? Students, professors, plant pathologists, microbiologists, or anyone interested in research and/or the history of plant pathology and biotechnology, will find this collection of papers an intriguing read.From the Preface: ??the journey is not over. As the commentary by Paul Hooykaas indicates, it looks as though T-DNA will insert into any cell, be it plant, fungal or even mammalian. Is there a possibility of using Agro?bacterium in gene therapy? Will Agrobacterium prove to be as useful a tool in fungal genetics as it has been in plant genetics? Its potential is mind-boggling.?

Book Description
As the oldest and largest human intervention in nature, the science of agriculture is one of the most intensely studied practices. From manipulation of plant gene structure to the use of plants for bioenergy, biotechnology interventions in plant and agricultural science have been rapidly developing over the past ten years with immense forward leaps on an annual basis. This book begins by laying the foundations for plant biotechnology by outlining the biological aspects including gene structure and expression, and the basic procedures in plant biotechnology of genomics, metabolomics, transcriptomics and proteomics. It then focuses on a discussion of the impacts of biotechnology on plant breeding technologies and germplasm sustainability. The role of biotechnology in the improvement of agricultural traits, production of industrial products and pharmaceuticals as well as biomaterials and biomass provide a historical perspective and a look to the future. Sections addressing intellectual property rights and sociological and food safety issues round out the holistic discussion of this important topic. Includes specific emphasis on the inter-relationships between basic plant biotechnologies and applied agricultural applications, and the way they contribute to each other Provides an updated review of the major plant biotechnology procedures and techniques, their impact on novel agricultural development and crop plant improvement Takes a broad view of the topic with discussions of practices in many countries

Book Description
Whilst genetic transformation of plants is commonly viewed as a means of bringing about plant improvement, it has not so readily been recognised as a tool for analysing the function of plant genes. This book is unusual in that it focuses on the genetic transformation of a range of plants using a number of different methods. Many plants have been found to be quite difficult to transform, and so various techniques were developed. These techniques include: Agrobacterium suspension drops, electroporation, PEG, "whiskers", and various biolistic methods. A chapter on intellectual and property rights is included.
