(Submitter supplied) Experimental research on the effects of abiotic stress over grapevine has mainly focused on water shortage. The adaptation of plants to stress is a complex response triggered by cascades of molecular networks involved in stress perception, signal transduction, and the expression of specific stress-related genes and metabolites. Approaches such as array-based transcript profiling allow assessing the expression of thousands of genes in control and stress tissues. more...

(Submitter supplied) Background: 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 physiological, transcript, and protein levels. There are well-known differences in grapevine rootstocks responses to dehydration. We used time-series transcriptomic approaches combined with network analyses to elucidate and identify important physiological processes and network hubs that respond to dehydration in three different grapevine species differing in their drought tolerance. more...

(Submitter supplied) At the onset of ripening (veraison), Vitis vinifera L. cv Muscat Hamburg fruiting cuttings were exposed to four different environmental regimes in two growth chambers set up: 20/15ºC (day/night) and 30/25ºC (day/night) and with two different photosynthetic photon flux density (PPFD) conditions (200 and 400 μmol•m−2•s−1 PPFD) at grape bunch level during a 14 h photoperiod. Fruiting cuttings were selected to have similar grape bunch size avoiding changes in berry quality. more...

(Submitter supplied) Salt tolerance in grapevine is associated with the exclusion of chloride ions (Cl–) from the shoot. The rate-limiting step for this process has been identified as the passage of Cl– between the root symplast and the xylem apoplast through membrane integral proteins. To identify candidate genes for these proteins we used a custom microarray to compare the root transcriptomes of three grapevine varieties (Vitis spp.) that differ in their capacity to exclude Cl– from shoots. more...

(Submitter supplied) Grapevine (Vitis vinifera L.) is an economically important crop with a wide geographical distribution, reflecting its ability to grow successfully in a range of climates. However, many vineyards are located in regions with seasonal drought, and these are often predicted to be global climate change hotspots. Climate change affects the entire physiology of grapevine, with strong effects on yield, wine quality and typicity, making it difficult to produce berries of optimal enological quality and consistent stability over the forthcoming decades. more...

(Submitter supplied) Grapevine rootstock 1616C shoots were sterilized and cultured on Murashige & Skoog (MS) medium containing 2% sucrose (w/v). Plantlets were grown in a growth chamber with a 16-h light/8-h dark cycle for 10 weeks at 25 °C. Plantlets with 4–5 leaves were chosen for use in stress treatments. Experiments were conducted with treatment groups: The control (C, without any chemical treatment), TM (treated with 5 μg mL-1 tunicamycin (TM)) and salt (treated with 400 mM NaCl). more...

(Submitter supplied) BiP overexpression confers resistance to drought, through an as yet unknown mechanism that is related to ER functioning, has been described that the delay in leaf senescence by BiP overexpression might relate to the absence of the response to drought. We used microarrays to detail the global programme of gene expression underlying in soybean leaves overexpressing BiP and with different water potentials to elucidate the mechanisms by which BiP protects plant cells against cell death induced by dehydration.

(Submitter supplied) Oxidative stress can arise when in vitro propagated plants developed under low light conditions are exposed to high light during transfer to ex vitro conditions. In such a situation, among the many potential stresses to which the transferred plant can be exposed, oxidative stress is commonly experienced, most likely brought about by absorption of light energy in excess of that required for very low levels of photosynthetic metabolism. more...

(Submitter supplied) Pierce’s disease, caused by the bacterium Xylella fastidiosa, is one of the most devastating diseases of cultivated grapes. To test the long-standing hypothesis that Pierce’s disease results from pathogen-induced drought stress, we used the Affymetrix Vitis GeneChip to compare the transcriptional response of Vitis vinifera to Xylella infection, water deficit, or a combination of the two stresses. The results reveal a massive redirection of gene transcription involving 822 genes with a minimum 2-fold change (p<0.05), including the upregulation of transcripts for phenylpropanoid and flavonoid biosynthesis, pathogenesis related (PR) proteins, absisic acid (ABA)/jasmonic acid (JA)-responsive transcripts, and down-regulation of transcripts related to photosynthesis, growth and nutrition. more...

(Submitter supplied) By sequencing 36 cDNA libraries with Illumina technology, we identified genes differentially expressed in soybean plants in response to water deficit and genes that were either up- or down-regulated in different periods of the day. Of 54,175 predicted soybean genes (Glyma v1.1), 35.52% exhibited expression oscillations in a 24 h period. This number increased to 39.23% when plants were submitted to water deficit. more...

(Submitter supplied) Heat shock proteins (Hsps) are molecular chaperones primarily involved in maintenance of protein homeostasis. Their function has been best characterized in heat stress (HS) response during which Hsps are transcriptionally controlled by heat stress transcription factors (Hsfs). The role of Hsfs and Hsps in HS-response in tomato was initially examined by transcriptome analysis using the Massive Analysis of cDNA Ends (MACE) method. more...

(Submitter supplied) The first genome-wide transcriptomic atlas of grapevine (Vitis vinifera) is based on 54 diverse samples expressing ~93% of predicted grapevine genes. Pollen and senescent leaves have unique transcriptomes but microarray analysis grouped all other samples into vegetative/green or mature/woody categories based on maturity rather than organ identity. This fundamental transcriptome reprograming during maturation was highlighted by three distinct statistical approaches supported by gene coexpression analysis. more...

(Submitter supplied) Grapevine rupestris stem pitting-associated virus (GRSPaV) is a widespread virus affecting Vitis spp. Although it has established a compatible viral interaction in Vitis vinifera L. without the development of phenotypic alterations, it can occur as distinct variants that show different symptoms in diverse Vitis species. We investigated the changes induced by GRSPaV in V. vinifera cv Bosco, an Italian white grape variety, by combining agronomic, physiological, and molecular approaches, in order to provide comprehensive information about the global effects of GRSPaV. more...
