The main aim of this book is to provide a comprehensive text in a worldwide perspective of remote sensing in forestry. It is intended for those concerned with the management of forest resources, forestry students and researchers commencing studies on the remote sensing of the forest environment. The book is divided in five parts, aiming to provide a stepwise approach to studying applied remote sensing and also to facilitate the reader in proceeding directly to topics of interest. The first section focuses on the scientific and technological background. Later emphasis is placed on aerial photography and aerial photographic interpretation, since in field forestry aerial photographs are a major source of forest data extracted from remotely sensed imagery. Satellite remote sensing is a main field of research and increasingly used in forest inventory and management as well as in policy decisions.

For over 10 years, TMV -based vectors have been used as plant expression tools to examine gene regulation and function, protein processing, pathogen elicitors, to manipulate biosynthetic pathways, and to produce high levels of enzymes, proteins, or peptides of interest in different locations in a plant cell. TMV vectors often exhibit genetic stability of foreign RNA sequences through multiple passages in plant hosts. Foreign coding sequences can be expressed in plants where the stability, intracellular fate and enzymatic or biological activities of the recombinant proteins can be rapidly evaluated and optimized. These properties make viral vectors attracti ve expression vehicles for testing and production of a wide variety of recombinant peptides and proteins, for structural analyses of post-translational modifications and for assessing gene function and metabolic control. Finally, the utility of both CP fusion and dual subgenomic vectors has extended beyond the laboratory and greenhouse to field-scale production and purification of recombinant products for commercial use (Grill, 1992; Grill, 1993; Turpen et at. , 1997).
