(Submitter supplied) Winter season with reduced day length (photoperiod); led to the growth cessation, dormancy induction and cold acclimation in woody perennial plants. To develop an understanding of the photoperiod signal transduction in Vitis riparia; shoot tip transcriptome profiling was performed under differential photoperiod treatments (long (LD, 15h) and short day (SD, 13h)) for 7 or 21 days after shoots reached 10 nodes (LD7, SD7, LD21 or SD21).

(Submitter supplied) The transition of axillary grapevine buds from paradormancy to endodormancy is an important mechanism for winter survival. Maintenance of paradormancy and transition to endodormancy may be synchronized by factors including phytohormones, genes, transcription factors and other molecular regulators. In the present study we used age matched buds from vines subjected to 28 days of short day (SD; 13h) treatment or continued long day (LD; 15h) photoperiod for high throughput transcriptome profiling.

(Submitter supplied) Dormant grapevine buds from 4 genotypes were collected over a variable time series after being exposed to growth room temperatures. Buds were collected from the field during winter and assessed for the loss of cold hardiness (deacclimation) in tandem with analysis of gene expression changes. DEGs are examined for various enriched pathways. Wild grapevines deacclimate faster than cultivated grapevines and the entire gene regulation cascade was also faster in wild grapevines. 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) Some insects can redirect plant development to form unique organs called galls, which provide these insects with unique, enhanced food and protection from enemies and the elements. Many galls resemble flowers or fruits, suggesting that elements of reproductive development may be involved. We addressed this possibility using RNA sequencing (RNAseq) to quantify the transcriptional responses of wild grapevine (Vitis riparia Michx.) leaves to a galling parasite, phylloxera (Daktulosphaira vitifoliae (Fitch 1855)). 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) Bud endodormancy induction response of two genotypes (‘Seyval’ a hybrid white wine grape and V. riparia, PI588259 a native north american species) was compared under long and short photoperiod. Three separate replicates (5 plants/replicate) were treated in each of 2 separate years (2007 and 2008) to generate paradormant (LD) and same aged endodormancy-induced (SD) buds for transcriptomic, proteomic and metabolomic analysis. more...

(Submitter supplied) Plasmopara viticola (Berk. and Curt.) Berl. and de Toni is the agent of the destructive disease known as grapevine downy mildew, for the control of which intensive fungicide treatments are required. Natural sources of resistance are available in several wild Vitis species, which are being used in traditional breeding approaches. However, molecular switches, signals and effectors involved in resistance are poorly understood. more...

(Submitter supplied) A grape-bud-oriented genomic platform was produced for a large-scale comparative analysis of bud responses to two stimuli of grape-bud dormancy release, hydrogen cyanamide (HC) and heat shock (HS). The results suggested considerable similarity in bud response to the stimuli, both in the repertoire of responding genes and in the temporary nature of the transcriptome reprogramming. Nevertheless, the bud response to HC was slower, more condensed and stronger, as reflected by a higher number of regulated genes and a higher intensity of regulation compared to the response to HS.
