Viruses that infect plants are responsible for reduction in both yield and quality of crops around the world, and thus are of great economic importance. This has provided the impetus for the extensive research into the molecular and cellular biology of these pathogens and into their interaction with their plant hosts and their vectors. However, interest in plant viruses extends beyond their ability to damage crops. Many plant viruses - for example, tobacco mosaic virus - have been used as model systems to provide basic understanding of how viruses express genes and replicate. Others permitted the elucidation of the processes underlying RNA silencing, now recognized as a core epigenetic mechanism underpinning numerous areas of biology. This book attests to the huge diversity of research in plant molecular virology. Written by world authorities in the field, the book opens with two chapters on the translation and replication of viral RNA. Following chapters cover topics such as viral movement within and between plants, plant responses to viral infection, antiviral control measures, virus evolution, and newly emerging plant viruses. The book concludes with two chapters on biotechnological applications of plant viruses. Throughout, the focus is on the most recent, cutting-edge research, making this book essential reading for everyone working with plant viruses.For example, the amplification of LTR-retrotransposons has resulted in the doubling of the maize genome over 3 ... suggesting horizontal transfer of these elements, perhaps mediated by a vector (Cheng et al., 2009; Roulin et al., 2009). ... end-joining (also known as illegitimate recombination), the main method of repair of double-stranded DNA breakages in higher ... Plant endogenous viral sequences The discovery of endogenous viral sequences in a plant species was serendipitous.
