Bats act as reservoirs for over 200 viruses, many of which cause severe, often life-threatening, diseases in humans, livestock and wildlife. Examples include rabies virus, SARS and MERS coronaviruses and Ebola virus. Surprisingly many of these viruses cause asymptomatic infections in bats. In fact it has been postulated that these viral infections may even confer a benefit (as yet unknown) to the bat host. Research into the molecular and cellular biology of the virus-host interaction and studies on the immune systems of the bat hosts are providing new insights into these fascinating viruses and are essential first steps for the development of novel strategies for the prevention of bat-borne zoonotic infections. In this multi-authored volume, international experts review the current hot-topics in this field. Chapters have extensive reference sections that should encourage readers to pursue each subject in greater detail. The book opens with an introductory chapter that is followed by six chapters (chapters 2-7) reviewing different important families of bat-borne viruses. The following two chapters (chapters 8-9) focus on the bat immune system. Chapters 9-12 cover in vitro isolation, in vivo models and metagenomics for viral discovery in bats. The book closes with a fascinating look at the special ability of bats to act as reservoirs for so many different types of viruses. This book is an invaluable reference source of timely information for students, virologists, immunologists, medical and veterinary professionals, and scientists working on bat-borne diseases. It is also highly recommended for all university libraries.

Cyanobacteria constitute a substantial part of an oceanic phytoplankton and continue supplying the atmosphere with oxygen at the amounts comparable to those produced by higher plants of forests and fields. Compared with studying photosynthesis in plants, the major advantage of cyanobacteria is their relative simplicity and ease of manipulation. This makes cyanobacteria the ideal model organisms, not only to study photosynthesis but also the biological response to environmental stress. This makes understanding the regulatory systems of cyanobacteria an important area of research. In this book Dr Los reviews the current research with experimental stressors and how these can be used to search for and to identify the regulatory molecules and circuits of cyanobacterial cells. Topics covered include: cyanobacterial genetic systems responsible for acclimation to changing environment, including the two-component regulatory system, eukaryotic-type serine-threonine protein kinases, sigma subunits of RNA polymerase, transcription factors, and some other regulators of gene expression in response to various factors. This book will be essential for anyone with an interest in cyanobacteria, stress responses, photosynthesis, nitrogen fixation and biotechnology.

Viral diseases of crop plants cause significant yield and economic losses and this poses a major threat to global food security. To make matters worse there are no effective antiviral chemicals available and, although naturally resistant host genotypes exist, they are so rare that conventional breeding techniques cannot be used reliably to create resistant plants. The most effective option to combat phytopathogenic viruses is through biotechnological intervention, such as the use of genetic engineering to develop transgenic plants or the topical use of RNA silencing technologies to prevent or modulate the severity of the viral infection. Since the first report on the virus resistance of transgenic tobacco plants in 1986, enormous progress has been made in this field. In addition great strides have been made in our ability to genetically manipulate plants and viruses leading to a plethora of novel applications. This has prompted the need for this timely book which distills the most important research to provide a timely overview. This authoritative book contains fifteen chapters whose breadth reflects the diversity of this research area. Topics covered range from: understanding the mechanisms of virus resistance in plants, and the management of whitefly-transmitted viruses, to the principles and methods involved in genetic engineering of virus resistant plants. Other chapters cover individual crops such as papaya, cassava, rice, tomato, and banana, for which virus resistance has been accomplished by employing different transgenic technologies. This volume is essential reading for everyone working in this field, both students and specialists, from academia, research institutes/organizations and industries.

Over the last fifteen years a large collection of protozoan parasite genomes have been sequenced, annotated and made available on public databases.

Viruses of microorganisms (VoMs) are the world's most abundant viruses. There are viruses for every known microbe and VoMs are usually described in terms of their hosts as algal viruses, archaeal viruses, bacteriophages, virophages, fungal viruses and protozoan viruses. A key feature of infection by VoMs is that they often kill the host. This allows VoMs to play a key role in modifying microbial communities and in nutrient cycling in various environments. When the host is itself a pathogen then VoMs may be exploited to create novel antimicrobial strategies. In fact phage therapy for a variety of antibiotic-resistant bacterial pathogens is currently at the clinical trial stage. When they don't kill the host, VoMs can still play important roles in the ecology and evolution of their hosts via various forms of virus-mediated horizontal gene transfer. Important in nature, these processes have also been used in the laboratory in genetic engineering techniques. In this multi-authored volume, international experts review the genomics, ecology, comparative biology and biotechnological applications of these fascinating viruses. Chapters have extensive reference sections that should encourage readers to pursue each subject in greater detail. This unique reference volume is a must-read for everyone working with VoMs, from the PhD student to the experienced scientist, in academia, the pharmaceutical or biotechnology industries and working in clinical environments.
