Open AccessDrought tolerance of the grapevine, Vitis champinii cv. Ramsey, is associated with higher photosynthesis and greater transcriptomic responsiveness of abscisic acid biosynthesis and signaling
Grapevine is an economically important crop for which yield and berry quality is strongly affected by climate change. Large variations in drought tolerance exist across Vitis species. Some of these species are us...

Open AccessA sense of place: transcriptomics identifies environmental signatures in Cabernet Sauvignon berry skins in the late stages of ripening
Grape berry ripening is influenced by climate, the main component of the “terroir” of a place. Light and temperature are major factors in the vineyard that affect berry development and fruit metabolite composi...

Open AccessTranscriptomic response is more sensitive to water deficit in shoots than roots of Vitis riparia (Michx.)
Drought is an important constraint on grapevine sustainability. Vitis riparia, widely used in rootstock and scion breeding, has been studied in isolated leaf drying response studies; however, it is essential to i...

Open AccessThe common transcriptional subnetworks of the grape berry skin in the late stages of ripening
Wine grapes are important economically in many countries around the world. Defining the optimum time for grape harvest is a major challenge to the grower and winemaker. Berry skins are an important source of f...

Open AccessTranscriptomic network analyses of leaf dehydration responses identify highly connected ABA and ethylene signaling hubs in three grapevine species differing in drought tolerance
Grapevine is a major food crop that is affected by global climate change. Consistent with field studies, dehydration assays of grapevine leaves can reveal valuable information of the plant’s response at physio...

Article
Open AccessAbscisic acid transcriptomic signaling varies with grapevine organ
Abscisic acid (ABA) regulates various developmental processes and stress responses over both short (i.e. hours or days) and longer (i.e. months or seasons) time frames. To elucidate the transcriptional regulat...

Open AccessTranscriptomic analysis of the late stages of grapevine (Vitis vinifera cv. Cabernet Sauvignon) berry ripening reveals significant induction of ethylene signaling and flavor pathways in the skin
Grapevine berry, a nonclimacteric fruit, has three developmental stages; the last one is when berry color and sugar increase. Flavors derived from terpenoid and fatty acid metabolism develop at the very end of...

Article
Open AccessMetabolite and transcript profiling of berry skin during fruit development elucidates differential regulation between Cabernet Sauvignon and Shiraz cultivars at branching points in the polyphenol pathway
Grapevine berries undergo complex biochemical changes during fruit maturation, many of which are dependent upon the variety and its environment. In order to elucidate the varietal dependent developmental regul...

Article
Open AccessProteomic analysis indicates massive changes in metabolism prior to the inhibition of growth and photosynthesis of grapevine (Vitis viniferaL.) in response to water deficit
Cabernet Sauvignon grapevines were exposed to a progressive, increasing water defict over 16 days. Shoot elongation and photosynthesis were measured for physiological responses to water deficit. The effect of ...

Open AccessEffects of abiotic stress on plants: a systems biology perspective
The natural environment for plants is composed of a complex set of abiotic stresses and biotic stresses. Plant responses to these stresses are equally complex. Systems biology approaches facilitate a multi-tar...

Article
Compatible GLRaV-3 viral infections affect berry ripening decreasing sugar accumulation and anthocyanin biosynthesis in Vitis vinifera
Virus infections in grapevine cause important economic losses and affect fruit quality worldwide. Although the phenotypic symptoms associated to viral infections have been described, the molecular plant respon...

Article
Open AccessIdentification of tissue-specific, abiotic stress-responsive gene expression patterns in wine grape (Vitis viniferaL.) based on curation and mining of large-scale EST data sets
Abiotic stresses, such as water deficit and soil salinity, result in changes in physiology, nutrient use, and vegetative growth in vines, and ultimately, yield and flavor in berries of wine grape, Vitis vinifera ...

Integrating Functional Genomics With Salinity and Water Deficit Stress Responses in Wine Grape - Vitis Vinifera
Wine grape (Vitis vinifera) is the world’s most important fruit crop both in terms of crop production and economic value. For most crops, water deficit stress has negative implications for production and quality....

Differential effects of salinity on leaf elongation kinetics of three grass species
This study focuses on the inhibitory effect of salinity on the leaf extension of three different grass species: Hordeum jubatum L., Hordeum vulgare L. and Zea mays L. Leaf elongation rates (LER) were measured on ...

Chapter
Sodium-Calcium Interactions Under Salinity Stress
There are a wide range of responses of plants to salinity which involve interactions of Na with Ca. Plant processes such as growth, photosynthesis, mineral nutrition, water and ion transport are affected by th...

Article
Abscisic acid concentrations are correlated with leaf area reductions in two salt-stressed rapid-cycling Brassica species
The greater sensitivity of B. carinata to salinity in comparison to B. napus has been linked to a greater reduction in net assimilation rate. Apparently this is not due to ion toxicity; the cause is unknown. In t...

Article
Supplemental calcium does not improve growth of salt-stressed Brassicas
Whole plant and callus cultures of different rapid-cycling Brassica species were treated with salinity (8 dS m-1) and/or supplemental Ca (up to 10 mM total concentration). None of these cultures responded to supp...

Article
Growth and ion accumulation of two rapid-cycling Brassica species differing in salt tolerance
The response of two rapid-cycling Brassica species differing in tolerance to seawater salinity was studied over a period of 24 days. In response to 8 dS m−1 salinity, the two Brassica species showed clear differe...

Supplemental calcium does not improve growth of salt-stressed brassicas
Whole plant and callus cultures of different rapid-cycling Brassica species were treated with salinity (8dS m−1) and/or supplemental Ca (up to 10 mM total concentration). None of these cultures responded to suppl...

Growth and mineral nutrition of six rapid-cycling Brassica species in response to seawater salinity
The growth of six rapid-cycling lines of Brassica species, B. napus, B. campestris, B. nigra, B. juncea, B. oleracea and B. carinata was inhibited by seawater salinity. Based on the change in dry matter reduction...
