cline and red blotch can result in total crop loss several years post-infection. This situation is further exacerbated by mixed infections with multiple viruses and other biotic as well as adverse abiotic environmental conditions, such as drought and winter damage, causing even greater destruction. The book builds upon the last handbook (written over twenty years ago) on the part of diagnostics and extensively expands its scope by inclusion of molecular biology aspects of select viruses that are widespread and economically most important.  This includes most current information on the biology, transmission, genome replication, transcription, subcellular localization, as well as virus-host interactions.  It also touches on several novel areas of scientific inquiry. It also contains suggested directions for future research in the field of grapevine virology.  weiterlesen
