(Submitter supplied) Hydrogen cyanamide (HC) is an agrochemical compound frequently used to break bud dormancy in grapevine grown under mild winter conditions all over the world. The present study was carried out to get a better understanding of the molecular mechanism associated with HC to release bud dormancy in grapevine using RNA-seq based transcriptomic and tandem mass tag (TMT) based proteomic analysis.

(Submitter supplied) We used Illumina RNA-Seq technology to carry out digital gene expression profiling of Dormant and non dormant buds of Shine Muscat Cultivar.127 pathways were annotated by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and metabolic, biosynthesis of secondry metabolite and. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis demonstrated that DEGs were involved in various metabolic processes, including phytohormone metabolism. 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.

(Submitter supplied) Bud dormancy is a crucial stage in perennial trees and allows survival over winter and optimal subsequent flowering and fruit production. Environmental conditions, and in particular temperature, have been shown to influence bud dormancy. Recent work highlighted some physiological and molecular events happening during bud dormancy in trees. However, we still lack a global understanding of transcriptional changes happening during bud dormancy. more...

(Submitter supplied) Perennial plants, like fruit trees grown in temperate regions, are characterized by bud dormancy, a rest state that protects the bud from cold during winter. At the same time, these plants have developed a requirement for winter chill for correct flowering. However, winters are becoming increasingly warm in temperate regions, resulting in dramatic effects on the flowering output and therefore crop yield. more...

(Submitter supplied) Heat stress is one of the primary abiotic stresses that limit crop production . Grape is a popular cultivated fruit with high economic value throughout the world, and whose growth and development is often influenced by high temperature. Alternative splicing (AS) is a widespread mechanism increasing transcriptome complexity and proteome diversity. We conducted high temperature treatments (35oC, 40oC and 45oC) on grapevines (Vitis vinifera), and assessed proteomic and transcriptomic （especially AS）changes in leaves. 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) Cold cataract is the reversible opacification of the lens when the temperature decreases. However, we observed that when temperature of the rats lens was maintained at a lower temperature for a prolonged time, the opacification of lens was only partly reversible. To review the potential molecular mechanism of the irreversible part of opacification under cold stimulation, we applied comparative transcriptomic and proteomic analysis to systematically investigate the molecular changes that occurred in the lens capsules of rats under low temperature treatments. more...
