Plant Virus-Host Interaction contains cutting-edge research in plant molecular virology, including pathogenic viroids and transport by insect vectors, interference with transmission to control viruses, and synergism, with pivotal coverage of RNA silencing and the counter-defensive strategies used by viruses to overcome the silencing response in plants.

With a clear focus on plant virus evolution, including quantitative and population genetics, Plant Virus-Host Interaction provides insights on the major factors favoring disease emergence, such as genetic change in pathogen and host populations and changes in host ecology and environment. The book also examines socioeconomic implications of widespread plant viral agents. Contributions from leading experts around the globe provide varied perspectives, while comprehensive coverage ensures a complete look at this exciting field.

There has been recent rapid progress in the transformation of plants with foreign DNA, making use either of the natural routes of genetic invasion that viruses and bacteria have developed, or of chemical, mechanical and electrical tricks to make plant protoplast membranes permeable to nucleic acids. Genes integrated into plant virus genomes can be carried systemi­ cally from the initial site of infection into the rest of the plant. Genes placed between the borders of Agrobacterium tumefaciens T-DNA can be transferred into single cells or plant tissue, which then divides to produce wound calli, or as in the case of an Agrobacterium rhizogenes infection, grow out into new roots. Calli and roots can be grown into whole plants. If virus genomes are placed between the T-DNA borders, a very effective infectious route, termed "agroinfection", is established. Once inside a pro­ toplast, DNA finds its way into the nucleus where it can finally integrate into the resident chromosome and be expressed. Whether it can also find its way into chloroplasts is not yet clear, but at least translation products can be targeted into this organelle. Regeneration of whole organisms from single cells is a special feature of plants and offers a unique tool to study genes in a multicellular organism. In addition, as in animal cells, transcription and translation of trans­ forming genes can be studied in plant cells during "transient expression".

Stark. Lebendig. Inspirierend.Spanien, 16. Jahrhundert: Das Schicksal einer Frau ist vorgezeichnet: Ehe oder Kloster. Doch Teresa von Avila liebt ihre Unabhängigkeit und ist nicht bereit, andere über sich bestimmen zu lassen. Verzweifelt und mit unbändiger Lebenslust sucht sie trotz aller Rückschläge ihren Weg.Die spätere Schutzpatronin Spaniens begehrt mutig auf und startet ein lebensgefährliches Unterfangen, um ihren Traum zu verwirklichen. Aber nicht nur die Macht der Inquisition tritt ihr entgegen.Diese einmalige und zugleich so menschliche Mystikerin erschüttert mit ihrer Vision die damalige Welt. Ihr Wirken inspiriert und berührt einst wie heute.Teresa von Avila - Die faszinierende Geschichte ihres Lebens.

A recent volume of this series (Signals and Signal Transduction Pathways in Plants (K. Palme, ed.) Plant Molecular Biology 26, 1237-1679) described the relay races by which signals are transported in plants from the sites of stimuli to the gene expression machinery of the cell. Part of this machinery, the transcription apparatus, has been well studied in the last two decades, and many important mechanisms controlling gene expression at the transcriptional level have been elucidated. However, control of gene expression is by no means complete once the RNA has been produced. Important regulatory devices determine the maturation and usage of mRNA and the fate of its translation product. Post-transcriptional regulation is especially important for generating a fast response to environmental and intracellular signals. This book summarizes recent progress in the area of post-transcriptional regulation of gene expression in plants. 18 chapters of the book address problems of RNA processing and stability, regulation of translation, protein folding and degradation, as well as intracellular and cell-to-cell transport of proteins and nucleic acids. Several chapters are devoted to the processes taking place in plant organelles.
