Only one generation ago, entomology was a proudly isolated discipline. In Comstock Hall, the building of the Department of Entomology at Cornell University where I was first introduced to experimental science in the laboratory of Tom Eisner, those of us interested in the chemistry of life felt like interlopers. In the 35 years that have elapsed since then, all of biology has changed, and entomology with it. Arrogant molecular biologists and resentful classical biologists might think that what has happened is a hostile take-over of biology by molecular biology. But they are wrong. More and more we now understand that the events were happier and much more exciting, amounting to a new synthesis. Molecular Biology, which was initially focused on the simplest of organisms, bacteria and viruses, broke out of its confines after the initial fundamental questions were answered - the structure of DNA, the genetic code, the nature of regulatory genes - and, importantly, as its methods became more and more generally applicable. The recombinant DNA revo lution of the 1970s, the development of techniques for sequencing macromolecules, the polymerase chain reaction, new molecular methods of genetic analysis, all brought molecular biology face to face with the infinite complexity and the exuber ant diversity of life. Molecular biology itself stopped being an isolated diScipline, pre occupied with the universal laws of life, and became an approach to addressing fas cinating specific problems from every field of biology.

La biologie moléculaire a bouleversé les sciences du vivant L'explosion de la génomique, qui propose des séquences de génomes entiers ainsi que des approches globales de leur fonctionnement, en est un exemple récent. L'objectif de cet ouvrage présenté sous forme de fiches n'est pas de détailler des protocoles ou des recettes toutes faites, mais d'expliquer simplement les principes théoriques des techniques de biologie moléculaire. Cette édition mise à jour propose des illustrations nouvelles et présente notamment de nombreuses techniques de génomique récemment apparues dans les laboratoires. Cet ouvrage s'adresse à toute personne - spécialiste ou non - curieuse de connaître les bases des différentes techniques de manipulation des acides nucléiques.

the discovery of the "splicing" of the gene transcripts, the list would include the whole molecular genetics of the lambda bacteriophage, the notions of "promotor," "repressor," and "integration," the discovery of the reverse flow of genetic information, the very existence of oncogenes, the S'-terminal "cap" struc ture of eukaryotic mRNAs, ... Electronmicroscopy, ultracentrifugation and tissue culture were the landmarks on the way of the young science. During the past few years, however, a major (and not so silent) revolution took place: recombinant DNA technology with all its might entered in our laboratories, and restriction mapping of cloned genomes and sequencing gels have replaced plaque counting and sucrose gradients. The new techniques have made it possible to "dissect" the entire genome of a virus at the molecular level, and studies that would have been dreamt of just in the mid-seventies became the everyday experiments of our days. With new insight into the structure of viral genomes, and a deeper understanding of the mechanisms that regulate their expression, our view of viruses was bound to change: this volume bears witness to this impressive advance.

With the underpinning role of forage legumes in the nitrogen economy and animal productivity from temperate grasslands certain to expand in the future, particularly in regions where their potential has not yet been realized, it is essential that the wealth of information currently available is widely disseminated. This book serves the purpose with very detailed information on and illustrations of 35 selected forage legume species that will contribute to more efficient and viable grassland farming.

This book provides insights into general experimental strategies and quite detailed accounts of experiments in molecular neuroscience. It is useful to final year undergraduates and post-graduates interested in the impact that the new science of molecular biology is having on neuroscience.
