Les 7e Rencontres méridionales de Préhistoire récente, tenues à Bron, sur le campus de l'Université Lumière-Lyon 2, les 3 et 4 novembre 2006, ont réuni plus de 150 préhistoriens venus du Sud de la France et des régions alentour. Ces Rencontres biennales représentent le lien majeur de la communauté des chercheurs pour les périodes allant du Mésolithique à l'Âge du Bronze dans la moitié sud de la France. Les Actes présentés ici regroupent 24 contributions réparties en deux sections : l'actualité de la recherche, présentant les principaux résultats des fouilles et programmes récents, et le thème spécifique choisi pour cette session « Économie et société à la fin de la Préhistoire ». Cette thématique large est abordée au fil de 9 contributions très ciblées portant sur les économies de subsistance, de production et d'échange ainsi que sur l'analyse de structures immobilières qui en témoignent, où l'on voit que l'idéel et le matériel ne sont jamais très éloignés dans ces sociétés du passé.

This book presents a general picture of our current understanding of plant embryology from the formation of floral organs concerned with embryological processes to the genetic manipulation of embryos. Against the background of classical embryological studies, chapters in this book highlight, from a molecular-genetic perspective, investigations on the development of the male and female reproductive units, male sterility, incompatibility, fertilisation, embryo and endosperm development, storage protein synthesis and adventive embryogenesis in flowering plants. Dramatic new developments in molecular biology and genetic engineering techniques have opened up new frontiers in our commercial exploitation of flowering plants. Manipulation of embryological processes to improve the quantity and quality of plant food products is one of the cherished goals of plant biologists and the work described in this book provides the up-to-date fundamental information necessary to achieve this goal. Plant biotechnologists, and cell and molecular biologists will find this book to be an invaluable reference and source book on plant embryogenesis.
