The domestication of grapes dates back five thousand years ago and has spread to nearly all continents. In recent years, grape acreage has increased dramatically in new regions, including the United States of America, Chile, Asia (China and India), and Turkey. A major limiting factor to the sustained production of premium grapes and wines is infections by viruses. The advent of powerful molecular and metagenomics technologies, such as molecular cloning and next generation sequencing, allowed the discovery of new viruses from grapes. To date, grapevine is susceptible to 64 viruses that belong to highly diverse taxonomic groups. The most damaging diseases include: (1) infectious degeneration; (2) leafroll disease complex; and (3) rugose wood complex. Recently, two new disease syndromes have been recognized: Syrah decline and red blotch. Losses due to fanleaf degeneration are estimated at $1 billion annually in France alone. Other diseases including leafroll, rugose wood, Syrah de 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.

Over 65 viruses are known to infect grapevines, more than any other agricultural crop. Growth, yield, and quality of virus-infected vines suffer, reducing the profitability to grape growers. Therefore, it is critical to identify grape cultivars resistant to these viruses which can be utilized to protect more susceptible varieties from infection. Wine grape cultivar Norton (Vitis aestivalis) and Chambourcin (V. vinifera hybrid), and rootstock St. George (V. rupestris) have been known to be disease tolerant. In the first study, Norton and Chambourcin were infected with Grapevine fleck virus (GFkV), Grapevine leafroll-associated virus 3 (GLRaV-3), Grapevine virus A (GVA), and Grapevine fanleaf virus (GFLV). Norton and V. rupestris 'St. George' were infected with Grapevine vein clearing virus (GVCV). Testing of virus-infected grapevines for each virus by the polymerase chain reaction (PCR) assays indicated that the three grape varieties are susceptible to the viruses tested, and, therefore, none should be utilized as virus-resistant cultivars. In the second study, a wild V. rupestris 'Scheele' vine was tested positive for GVCV, which is referred to as GVCV-VRU, marking the first instance this virus has been observed in the native wild V. rupestris population. The whole genome (7,755bp) of the new GVCV-VRU isolate was assembled. Sequence analysis revealed that GVCV-VRU and GVCV-CHA shared 92% nucleotide identity. The discovery of a new GVCV isolate in wild V. rupestris grapevine and its association with vein clearing disease may have important implications for origin and management of GVCV.

The Science of Grapevines: Anatomy and Physiology is an introduction to the physical structure of the grapevine, its various organs, their functions and their interactions with the environment. Beginning with a brief overview of the botanical classification (including an introduction to the concepts of species, cultivars, clones, and rootstocks), plant morphology and anatomy, and growth cycles of grapevines, The Science of Grapevines covers the basic concepts in growth and development, water relations, photosynthesis and respiration, mineral uptake and utilization, and carbon partitioning. These concepts are put to use to understand plant-environment interactions including canopy dynamics, yield formation, and fruit composition, and concludes with an introduction to stress physiology, including water stress (drought and flooding), nutrient deficiency and excess, extreme temperatures (heat and cold), and the impact and response to of other organisms. Based on the author’s years of teaching grapevine anatomy as well as his research experience with grapevines and practical experience growing grapes, this book provides an important guide to understanding the entire plant. Chapter 7 broken into two chapters, now "Environmental Constraints and Stress Physiology and Chapter 8 "Living with Other Organisms" to better reflect specific concepts Integration of new research results including: Latest research on implementing drip irrigation to maximize sugar accumulation within grapes Effect of drought stress on grapevine’s hydraulic system and options for optimum plant maintenance in drought conditions The recently discovered plant hormone – strigolactones – and their contribution of apical dominance that has suddenly outdated dogma on apical dominance control Chapter summaries added Key literature references missed in the first edition as well as references to research completed since the 1e publication will be added
