Our study has identified and analyzed the VvARF gene family that may be associated with the development of grape berry and other tissues. Auxin response factors (ARFs) are transcription factors that regulate the expression of auxin responsive genes through specific binding to auxin response elements (AuxREs). The ARF genes are represented by a large(More)
Increasing evidence suggests that heat acclimation and exogenous salicylic acid (SA) and abscisic acid (ABA) may lead to the enhancement of thermotolerance in plants. In this study, the roles that free SA, conjugated SA, ABA, and phosphatidylinositol-4,5-bisphosphate (PIP(2))-specific phospholipase C (PLC) play in thermotolerance development induced by heat(More)
Cell suspension cultures of Vitis vinifera were treated with chitosan and ultraviolet C (UV-C) irradiation, alone or in combination, to investigate the relationship between the production of stilbene and the transcript profiles of genes encoding the enzymes involved in stilbene synthesis. Treatment at the proper concentration or dosage enhanced both(More)
Vitis vinifera L. cv. Cabernet Sauvignon cell suspension cultures were treated with ultraviolet C (UV-C), methyl jasmonate (MeJA) and salicylic acid (SA), alone or in combination, to investigate the effects on stilbene biosynthesis. The application of elicitors at the proper dosage or concentration did not exert a negative effect on cell growth. All(More)
To explore the effects of harvest time on phenolic compounds during wine fermentation, grape berries (Vitis vinifera L. cv. Vidal) were harvested at 17.5, 22.8 and 37.2 masculine Brix and were used to make dry wine, semi-sweet wine and icewine with low alcohol levels, respectively. Phenolic acids and flavan-3-ols were assayed during the fermentation of(More)
This paper reports the capability of electronic nose based on gas chromatograph (GC-Flash) in age identification and brand classification of brandy. Three different kinds of brandies by the static headspace sampling for the injection of the volatile compounds were analyzed. The data were disposed by multivariate data processing based on principal component(More)
An efficient preparative separation method for Sphallerocarpus gracilis stems and leaves polyphenols (SGslP) was established in this study. An X-5 macroporous adsorption resin was selected for the purification of the SGslP, and the polyphenol content of the purified SGslP (PSGslP) was increased 5.11-fold from 8.29% to 42.38% after one treatment run. The(More)
Vitis vinifera L. cv. Cabernet Sauvignon cell suspension cultures were treated with oligochitosan (OCS) and sodium alginate (NaAlg) at various concentrations for different exposure times to investigate the effects on stilbene biosynthesis. In this study, adding optimal concentrations of OCS (100 mg l−1) and NaAlg (100 mg l−1) significantly enhanced both(More)
At high levels, copper in grape mash can inhibit yeast activity and cause stuck fermentations. Wine yeast has limited tolerance of copper and can reduce copper levels in wine during fermentation. This study aimed to understand copper tolerance of wine yeast and establish the mechanism by which yeast decreases copper in the must during fermentation. Three(More)
