Plants and animals have evolved ever since their appearance in a largely microbial world. Their own cells are less numerous than the microorganisms that they host and with whom they interact closely. The study of these interactions, termed microbial symbioses, has benefited from the development of new conceptual and technical tools. We are gaining an increasing understanding of the functioning, evolution and central importance of symbiosis in the biosphere. Since the origin of eukaryotic cells, microscopic organisms of our planet have integrated our very existence into their ways of life. The interaction between host and symbiont brings into question the notion of the individual and the traditional representation of the evolution of species, and the manipulation of symbioses facilitates fascinating new perspectives in biotechnology and health. Recent discoveries show that association is one of the main properties of organisms, making a more integrated view of biology necessary. Microbial Symbioses provides a deliberately "symbiocentric outlook, to exhibit how the exploration of microbial symbioses enriches our understanding of life, and the potential future for this discipline. - Offers a concise summary of the most recent discoveries in the field - Shows how symbiosis is acquiring a central role in the biology of the 21st century by transforming our understanding of living things - Presents scientific issues, but also societal and economic related issues (biodiversity, biotechnology) through examples from all branches of the tree of life

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.

Hardbound. This volume covers the dramatic advances which have been made in the lasttwo decades in the understanding of isoprenoid biosynthesis at thechemical, biochemical, and molecular genetic level. Tens of thousands ofisoprenoid metabolites - from pinenes to cholesterol, from ubiquinone tocarotene, from phytols to prenylated proteins, from dolichols togibberellins - have been isolated from essentially all forms of life, including prokaryotes, eukaryotes, and archaebacteria: from Escherichiacoli to mammals, from extremophiles and fungi to marine and terrestrialplants. All of these isoprenoids can be derived from a single, five-carbonacyclic precursor, isopentenyl diphosphate. Early chapters in this Volumedetail the key findings that have led to an understanding of the metabolicpathways leading to isopentenyl diphosphate, including both the classicalroute involving mevalonic acid as well as the recently discoveredpyruvate-triose phosphat

Molecular Biology of Plant Tumors provides an opportunity to learn in detail about the latest insights into the mechanism of transformation of plant cells by Agrobacterium tumefaciens. The study of the molecular mechanism responsible for the crown gall phenomenon (induced by Agrobacterium tumefaciens) illustrates the point that the fundamental study of the cause(s) and mechanism(s) of abnormal growth might be one of the most efficient ways to understand cellular differentiation and the molecular basis of gene expression. The book is organized into three parts that contain research on abnormal plant growth, crown gall tumors, and potential vectors for genetic engineering in agriculture. The genetic structure responsible for the neoplasmic transformation of plant cells in crown galls is a bacterial plasmid (called Ti for tumor-inducing). Research described in this volume demonstrates that these Ti plasmids were designed by evolution as natural gene vectors with which some bacteria can introduce active genes into plants. These transferred genes are maintained by integration in the plant genome and their expression is directly or indirectly responsible for the tumorous growth pattern.
