Book Description
Washington state is currently the second largest premium wine producer in the United States, with Vitis vinifera L. cv. Cabernet Sauvignon as one of the top produced varieties. Grape production in Washington not only depends on natural rainfall, but also on supplemental irrigation given the semi-arid climate. However, competition for agricultural water availability between grapes and other staple crops has become intense due to unstable climatic patterns and local policies, making efficient water management essential for sustainable viticulture and the development of the wine industry in Washington. Using Cabernet Sauvignon as a model variety, this project aimed to improve efficiency of water management by investigating the effects of novel irrigation strategies and watering regimes on grapevine physiology and grape production. Chapter one provides a comprehensive review of grapevine performance under water stress and discusses strategies to enhance water management in vineyards. Chapters two to four describe the implementation of a novel subsurface drip irrigation strategy named direct root-zone irrigation (DRZ) and summarize grapevine responses. Compared with traditional surface drip irrigation, DRZ increased leaf net CO2 assimilation rate and yield, reduced shallow root growth, and showed potential to save water and enhance crop water use efficiency without reducing grape quality. DRZ likely increased soil water availability but did not show significant effect on root growth in the deep soil profile. Finally, a greenhouse study described in chapter five investigated the responses of grapevine to four different watering regimes, which revealed that increasing watering rate after veraison did not improve grape yield and quality, but it helped improve carbon assimilation in leaves and relieved water stress in grapevines during later growing stages. Moreover, a negative correlation was found between peroxisome abundance in leaves and midday stem water potential, which provides a cellular readout to better understand grapevine growth under water deficit. Overall, this project provides new ways to improve water productivity and advances the understanding of physiological and molecular responses of grapevines to water stress.

Book Description
Grapes (Vitis spp.) are economically the most important fruit species in the world. Over the last decades many scientific advances have led to understand more deeply key physiological, biochemical, and molecular aspects of grape berry maturation. However, our knowledge on how grapevines respond to environmental stimuli and deal with biotic and abiotic stresses is still fragmented. Thus, this area of research is wide open for new scientific and technological advancements. Particularly, in the context of climate change, viticulture will have to adapt to higher temperatures, light intensity and atmospheric CO2 concentration, while water availability is expected to decrease in many viticultural regions, which poses new challenges to scientists and producers. With Grapevine in a Changing Environment, readers will benefit from a comprehensive and updated coverage on the intricate grapevine defense mechanisms against biotic and abiotic stress and on the new generation techniques that may be ultimately used to implement appropriate strategies aimed at the production and selection of more adapted genotypes. The book also provides valuable references in this research area and original data from several laboratories worldwide. Written by 63 international experts on grapevine ecophysiology, biochemistry and molecular biology, the book is a reference for a wide audience with different backgrounds, from plant physiologists, biochemists and graduate and post-graduate students, to viticulturists and enologists.

Book Description
This book describes the current state of international grape genomics, with a focus on the latest findings, tools and strategies employed in genome sequencing and analysis, and genetic mapping of important agronomic traits. It also discusses how these are having a direct impact on outcomes for grape breeders and the international grape research community. While V. vinifera is a model species, it is not always appreciated that its cultivation usually requires the use of other Vitis species as rootstocks. The book discusses genetic diversity within the Vitis genus, the available genetic resources for breeding, and the available genomic resources for other Vitis species. Grapes (Vitis vinifera spp. vinifera) have been a source of food and wine since their domestication from their wild progenitor (Vitis vinifera ssp. sylvestris) around 8,000 years ago, and they are now the world’s most valuable horticultural crop. In addition to being economically important, V. vinifera is also a model organism for the study of perennial fruit crops for two reasons: Firstly, its ability to be transformed and micropropagated via somatic embryogenesis, and secondly its relatively small genome size of 500 Mb. The economic importance of grapes made V. vinifera an obvious early candidate for genomic sequencing, and accordingly, two draft genomes were reported in 2007. Remarkably, these were the first genomes of any fruiting crop to be sequenced and only the fourth for flowering plants. Although riddled with gaps and potentially omitting large regions of repetitive sequences, the two genomes have provided valuable insights into grape genomes. Cited in over 2,000 articles, the genome has served as a reference in more than 3,000 genome-wide transcriptional analyses. Further, recent advances in DNA sequencing and bioinformatics are enabling the assembly of reference-grade genome references for more grape genotypes revealing the exceptional extent of structural variation in the species.
