(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) Drought has become an increasingly important constraint on grapevine sustainability due to global climate change. Vitis riparia, the only grapevine native to the upper Midwest region of the United States, is widely used in scion and rootstock breeding; however, it is not considered drought tolerant. In this study, RNA-Seq data were generated from grapevine root/shoot under WD and well-watered (control (C)) conditions to compare root signaling and shoot responses to water deficit.

(Submitter supplied) Background: 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 regulation of early responses of grapevine (Vitis vinifera) responding to ABA, different organs of grape (berries, shoot tips, leaves, roots and cell cultures) were treated with 10 μM (S)-(+)-ABA for 2 h. more...

(Submitter supplied) Background: Grapevine berry, a nonclimacteric fruit, goes through three developmental stages, the last one called the ripening stage, when the berry changes color and dramatically increases in sugar. Flavors derived from terpenoid and fatty acid metabolism develop at the very end of this ripening stage. Whole-genome microarray analysis was used to assess the transcriptomic response of pulp and skin of Cabernet Sauvignon berries in the latter stages of ripening between 22 and 37 °Brix. more...

(Submitter supplied) Drought stress is an adverse factor with deleterious effects on several aspects of rice growth. However, the mechanism underlying drought resistance in rice remains unclear. To understand the molecular mechanism of the drought response in rice, drought-sensitive CSSL (Chromosome Single-substitution Segment Line) PY6 was used to map QTLs of sensitive phenotypes and to reveal the impact of the QTLs on transcriptional profiling. 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 (Vitis vinifera L.) is importantly cultivated worldwide for table grape and wine production. Its cultivation requires irrigation supply, especially in arid and semiarid areas. Water deficiency can affect berry and wine quality mostly depending on the extent of plant perceived stress, which is a cultivar-specific trait. We tested the physiological and molecular responses to water deficiency of two table grape cultivars, Italia and Autumn royal, and we highlighted their different adaptation. more...

(Submitter supplied) Purpose: The plant hormone abscisic acid (ABA) coordinates responses leading to desiccation tolerance in all land plants. RNA-seq was employed to obtain differential expression data in response to ABA, dehydration and mannitol treatments in wild-type tissue. This was compared against the targeted gene knockout line PpanrKO. The ANR gene encodes a novel ABA regulator identified from ABA non-responsive (anr) mutant screens. more...

(Submitter supplied) Sporobolus stapfianus is a desiccation tolerant (DT) grass and a member of the Poaceae family alongside prominent crop and forage species. Despite the worldwide distribution of this family, most of its species are vulnerable to water loss within their vegetative tissues. As a DT species, S. stapfianus, could, therefore, serve as a model species for identifying the molecular changes that enabled such a rare occurrence of the DT phenotype in resurrection grasses and the implications of such a unique adaptation for agriculture. 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) ABI3 is a B3-domain transcription factor that acts as a master regulator of seed maturation. To identify genes that are regulated by this transcription factor in the model legume Medicago truncatula, Medicago hairy roots were generated using Agrobacterium rhizogenes transformed with the genomic sequence of the ABI3 gene of Medicago. Using the Medicago NimbleGen chip, a transciptomic analysis was performed to identify differentially expressed genes compared to the GUS expressed control.

(Submitter supplied) The molecular events that characterize postripening grapevine berries have rarely been investigated and are poorly defined. In particular, a detailed definition of changes occurring during the postharvest dehydration, a process undertaken to make some particularly special wine styles, would be of great interest for both winemakers and plant biologists. We report an exhaustive survey of transcriptomic and metabolomic responses in berries representing six grapevine genotypes subjected to postharvest dehydration under identical controlled conditions. more...
