 Molecular Biology of Plant Viruses by Chuni L. Mandahar, Two decades ago, recombinant DNA technology or genetic engineering ushered in a new era in the study of plant viruses. The major breakthrough came in the eighties, primarily due to the development of new methods for RNA reverse transcription and cDNA cloning, along with restriction enzyme mapping and rapid nucleotide sequencing. An information explosion in various molecular aspects of plant viruses was caused by these studies. Current research efforts investigate the study of viral genomes, genetic maps, genes and gene expression, gene products, and genetic basis of virus functions and biological properties. This book analyzes, collates and reviews such published information. Additionally, it demonstrates the mechanisms of genetic variability; brings out the molecular basis of virus transport in plants mad of virus transmission by vectors and of disease symptomatology; and discusses molecular biology of viroids and transgenic plants. It also treats the recently discovered genetic phenomenon of gene silencing and the gene-for-gene interactions between the hosts and plant viruses.
 DNA Topoisomerases in Cancer Therapy by Toshiwo Andoh, This volume commemorates the 30th anniversary of the discoveryin 1971 of the first DNA topoisomerases, i.e topoisomerase I in "E.coli," then provisionally named omega' protein, by the pioneeringwork of Jim Wang at Harvard University, who has contributed an articleto this volume: Reflections on an accidental discovery' of theenzyme. Many kinds of topoisomerase have since been found from type Ithrough to type VI in a variety of organisms ranging from viruses tohigher eukaryote mammals. The wide distribution of enzymes in variousforms of life implies that the DNA topoisomerase is essential forlife.In the mid 80's type I and II enzymes were found to be theintracellular targets of a number of efficacious anticancer drugs suchas doxorubicin, mitoxantrone, etoposide and camptothecin as a resultof a continued efforts of many investigators, especially Leroy Liu andhis collaborators at Johns Hopkins University. Readers will find aseries of chapters written by researchers actively engaged in theexpanding field of topoisomerase and their inhibitors. The series ofchapters cover review articles on pharmacology and the molecularmechanism of topoisomerase I- and II-targeting anticancer drugs inmammals and in the yeast Saccharomyces cerevisiae, which has proved tobe a superb model organism for studies of anticancer drugs. Thisvolume compiles up-to-date information on the topoisomerase-targetingcompounds in clinical and preclinical development as a useful andimportant reference book for students and researchers in the field ofpharmacology, toxicology, oncology and molecular biology.
DNA virus - A DNA virus is a virus that has DNA as its genetic material and does not use an RNA intermediate during replication. Viruses that either have RNA as their genetic material or use an RNA intermediate during replication are called RNA viruses. RNA virus - An RNA virus is a virus that either uses RNA as its genetic material, or whose genetic material passes through an RNA intermediate during replication. For example, Hepatitis B virus is classified as an RNA virus, even though its genome is double-stranded DNA, because the genome is transcribed into RNA during replication. Cauliflower mosaic virus - Cauliflower mosaic virus (CaMV) is the type member of the caulimoviruses, one of the six genera in the Caulimoviridae family, pararetroviruses that infect plants (Pringle, 1999). Pararetroviruses replicate through reverse transcription just like retroviruses, but the viral particles contain DNA instead of RNA (Rothnie et al. Feline leukemia virus - Feline leukemia virus (FeLV) is a retrovirus that infects cats. As a retrovirus, the genetic information of FeLV is carried by RNA instead of DNA.
