Aging in oak barrels is widely used in enology which could bring flavor changes and aromatic complexity to wines.In the present study,the aroma compounds were analyzed from the‘Merlot’dry red wines,which were fermented in two types of fermenters(stainless steel tank and rotated oak barrel)and aged in six types of oak barrels(three geographic origins×two toasting degrees)for different time(0,3,6 and 9 months,respectively).Results showed that 30 volatiles were associated with barrels and increased during oak aging.The fermenters could influence the intensities of the toast,leathery,smoky,fruity,floral and caramel aromas.The concentration of whisky lactone,eugenol,cis-isoeugenol,and the intensities of the toast and spicy aromas were highest in the wines aged in American oak and were lowest in the wines aged in French oak barrels.The concentrations of guaiacol,syringol,trans-isoeugenol,furfural alcohol,vanilla,cis-whisky lactone enabled the medium toasting barrels to be distinguished from the light toasting ones.The compounds originating from the barrels could be used to distinguish the types of different barrels,but the other general grape-derived and fermentation-derived volatiles could not.The fermenters,oak species and toasting degrees of the barrels all had significant effects on the aroma profiles of the aged‘Merlot’dry red wines,but the influence of the geographic origin was not obvious.

Constructing inbred lines for self-incompatible species and species with long generation times is challenging,making the use of F1 outcross/segregating populations the main strategy for genetic studies of such species.However,there is a lack of dedicated algorithms/tools for rapid quantitative trait locus(QTL)mapping using the F1 populations.To this end,we have designed and developed an algorithm/tool called OcBSA specifically for QTL mapping of F1 populations.OcBSA transforms the four-haplotype inheritance problem from the two heterozygous diploid parents of the F1 population into the two-haplotype inheritance problem common in current genetic studies by removing the two haplotypes from the heterozygous parent that do not contribute to phenotype segregation in the F1 population.Testing of OcBSA on 1800 simulated F1 populations demonstrated its advantages over other currently available tools in terms of sensitivity and accuracy.In addition,the broad applicability of OcBSA was validated by QTL mapping using seven reported F1 populations of apple,pear,peach,citrus,grape,tea,and rice.We also used OcBSA to map the QTL for flower color in a newly constructed F1 population of potato generated in this study.The OcBSA mapping result was verified by the insertion or deletion markers to be consistent with a previously reported locus harboring the ANTHOCYANIN 2 gene,which regulates potato flower color.Taken together,these results highlight the power and broad utility of OcBSA for QTL mapping using F1 populations and thus a great potential for functional gene mining in outcrossing species.For ease of use,we have developed both Windows and Linux versions of OcBSA,which are freely available at:https://***/Bioinformaticslab/OcBSA.

The widely appreciated muscat flavor of grapes and wine is mainly attributable to the monoterpenes that accumulate in ripe grape berries.To identify quantitative trait loci(QTL)for grape berry monoterpene content,an F1 mapping population was constructed by a cross between two grapevine genotypes,one with neutral aroma berries(cv.‘Beifeng’)and the other with a pronounced muscat aroma(elite Vitis vinifera line‘3–34’).A high-density genetic linkage map spanning 1563.7 cM was constructed using 3332 SNP markers that were assigned to 19 linkage groups.Monoterpenes were extracted from the berry of the F1 progeny,then identified and quantified by gas chromatography–mass spectrometry.Twelve stable QTLs associated with the amounts of 11 monoterpenes in berries were thus identified.In parallel,the levels of RNA in berries from 34 diverse cultivars were estimated by RNA sequencing and compared to the monoterpene content of the berries.The expression of five genes mapping to stable QTLs correlated well with the monoterpene content of berries.These genes,including the basic leucine zipper VvbZIP61 gene on chromosome 12,are therefore considered as potentially being involved in monoterpene metabolism.Overexpression of VvbZIP61 in Vitis amurensis callus through Agrobacterium-mediated transformation significantly increased the accumulation of several monoterpenes in the callus,including nerol,linalool,geranial,geraniol,β-myrcene,and D-limonene.It is hypothesized that VvbZIP61 expression acts to increase muscat flavor in grapes.These results advance our understanding of the genetic control of monoterpene biosynthesis in grapes and provide important information for the marker-assisted selection of aroma compounds in grape breeding.

Climate change and extreme weather pose significant challenges to the traditional viticulture regions.Emerging high-altitude grape-producing regions with diverse orientations have shown great potential in coping with this challenge.Stable,high-quality wine grape production may be achieved by synchronizing the meso-and microclimate.To clarify the role of high altitude and row orientation in meso-and microclimate and the response of berries to it,we evaluated seven years(2012-2018)of climate data,two years of basic grape(Cabernet Sauvignon,Vitis vinifera L.)quality,and one-year microclimate from veraison to harvest.By comparing two locations(Sidon 2047 m,Sinon 2208 m)in Yunnan Province,China,we found that the average temperature has been stable at approximately 15℃ for seven years,with no extreme weather or,noticeable global warming.The light intensity(LI)in the north-south(NS)was more balanced than the east-west(EW)direction,and the east-west to the south(EW-S)canopy side was almost higher than the other sides.High LI was associated with high photosynthetically active radiation(PAR),ultraviolet(UV),and infrared(IR)light and vice versa.The north-south to the east(NS-E)and east-west to the north(EWN)sides were characterized by lower LI and higher UV and IR light,and higher total anthocyanin content.Most anthocyanin synthesis-related genes,for example,VvF3'H and VvF3'5'H,were highly expressed in NS-E from veraison to maturity.Perhaps UV and IR light induced their expression.This study provides new insights on the role of differently orientated rows in controlling grape quality due to varied light quality.The findings are globally significant,particularly in the context of climate change,and offer fresh insights into berry physiological responses and decision-making for the management of existing vineyards.

Climate and water availability greatly affect each season’s grape yield and quality.Using models to accurately predict environment impacts on fruit productivity and quality is a huge challenge.We calibrated and validated the functional-structural model,grapevineXL,with a data set including grapevine seasonal midday stem water potential(�xylem),berry dry weight(DW),fresh weight(FW),and sugar concentration per volume([Sugar])for a wine grape cultivar(Vitis vinifera *** Franc)in field conditions over 13 years in Bordeaux,France.Our results showed that the model could make a fair prediction of seasonal�xylem and good-to-excellent predictions of berry DW,FW,[Sugar]and leaf gas exchange responses to predawn and midday leaf water potentials under diverse environmental conditions with 14 key parameters.By running virtual experiments to mimic climate change,an advanced veraison(i.***.the onset of ripening)of 14 and 28 days led to significant decreases of berry FW by 2.70%and 3.22%,clear increases of berry[Sugar]by 2.90%and 4.29%,and shortened ripening duration in 8 out of 13 simulated years,respectively.Moreover,the impact of the advanced veraison varied with seasonal patterns of climate and soil water availability.Overall,the results showed that the grapevineXL model can predict plant water use and berry growth in field conditions and could serve as a valuable tool for designing sustainable vineyard management strategies to cope with climate change.

Proanthocyanidins(PAs)and anthocyanins are involved in the response of plants to various environmental stresses.However,the mechanism behind defense-induced PA biosynthetic regulation is still not completely elucidated,also in grapevine.This study performed a transcriptome sequencing analysis of grape berries infected with Colletotrichum gloeosporioides to highlight the induction of the VabHLH137 factor from the basic helix-loop-helix(bHLH)XII subfamily by the fungus,which appeared to be significantly co-expressedwith PA-related genes.The functional analysis of VabHLH137 overexpression and knockdownin transgenic grape calli showed that it positively regulated PA and anthocyanin biosynthesis.Moreover,VabHLH137 overexpression in the grape calli significantly increased resistance to C.gloeosporioides.A yeast one-hybrid and electrophoretic mobility shift assay revealed that VabHLH137 directly bound to the VaLAR2 promoter,enhancing its activity and interacting with VaMYBPAR,a transcriptional activator of PA biosynthesis.Furthermore,transient experiments showed that although the VabHLH137+VaMYBPAR complex activated VaLAR2 expression,it failed to further enhance VaLAR2 expression compared to VaMYBPAR alone.The findings indicated that VabHLH137 enhanced PA biosynthesis by activating of VaLAR2 expression,providing new insight into the transcriptional regulation of defense-induced PA biosynthesis in grapevine.

grape is a widely cultivated crop with high economic value.Most cultivars derived from mild or cooler climates may not withstand increasing heat stress.Therefore,dissecting the mechanisms of heat tolerance in grapes is of particular significance.Here,we performed comparative transcriptome analysis of Vitis davidii‘Tangwei’(heat tolerant)and Vitis vinifera‘Jingxiu’(heat sensitive)grapevines after exposure to 25°C,40°C,or 45°C for 2 h.More differentially expressed genes(DEGs)were detected in‘Tangwei’than in‘Jingxiu’in response to heat stress,and the number of DEGs increased with increasing treatment temperatures.We identified a class B Heat Shock Factor,HSFB1,which was significantly upregulated in‘Tangwei’,but not in‘Jingxiu’,at high temperature.VdHSFB1 from‘Tangwei’and VvHSFB1 from‘Jingxiu’differ in only one amino acid,and both showed similar transcriptional repression activities.Overexpression and RNA interference of HSFB1 in grape indicated that HSFB1 positively regulates the heat tolerance.Moreover,the heat tolerance of HSFB1-overexpressing plants was positively correlated to HSFB1 expression level.The activity of the VdHSFB1 promoter is higher than that of VvHSFB1 under both normal and high temperatures.Promoter analysis showed that more TATA-box and AT∼TATA-box cis-elements are present in the VdHSFB1 promoter than the VvHSFB1 promoter.The promoter sequence variations between VdHSFB1 and VvHSFB1 likely determine the HSFB1 expression levels that inf luence heat tolerance of the two grape germplasms with contrasting thermotolerance.Collectively,we validated the role of HSFB1 in heat tolerance,and the knowledge gained will advance our ability to breed heat-tolerant grape cultivars.

Heat stress is one of the most serious threats in viticulture. Heat shock transcription factors(HSFs) have been proven to be the most important transcriptional factor family in the plant response to heat. In this study, a total of 19 putative HSF genes(VHSFs) were identified from the 12 × Vitis vinifera Pinot Noir PN4002 genome, and their chromosomal location, phylogenetic tree, exon-intron structure and conserved motifs were also analyzed. In addition, these HSFs transcriptional profiles in Vitis vinifera 'Jingxiu'(weak heat tolerance) and Vitis davidii 'Tangwei'(strong heat tolerance) under heat stress(47℃) and heat acclimation(38℃) were presented. Only VHSF01, VHSF05, VHSF15 and VHSF18 among 19 VHSFs showed different transcriptional models in these two genotypes under the same treatment, suggesting that these four VHSFs may be important factors which result in a thermotolerance difference between 'Jingxiu' and 'Tangwei'. This study provides novel insights into the response of 19 VHSFs to heat stress in the grape and suggests that potential key VHSFs in grape thermotolerance have great implications for molecular breeding in grapes.

The quality of planting materials is the foundation for productivity,longevity,and berry quality of perennial grapevines with a long lifespan.Manipulating the nursery light spectrum may speed up the production of healthy and high-quality planting vines but the underlying mechanisms remain elusive.Herein,the effects of different monochromatic lights(green,blue,and red)on grapevine growth,leaf photosynthesis,whole-plant carbon allocation,and transcriptome reprograming were investigated with white light as control.Results showed that blue and red lights were favorable for plantlet growth in comparison with white light.Blue light repressed excessive growth,significantly increased the maximum net photosynthetic rate(Pn)of leaves by 39.58%and leaf specific weight by 38.29%.Red light increased the dry weight of the stem by 53.60%,the starch content of the leaf by 53.63%,and the sucrose content of the stem by 230%.Green light reduced all photosynthetic indexes of the grape plantlet.Photosynthetic photon flux density(PPFD)/Ci–Pn curves indicated that blue light affected photosynthetic rate depending on the light intensity and CO2 concentration.RNA-seq analysis of different organs(leaf,stem,and root)revealed a systematic transcriptome remodeling and VvCOP1(CONSTITUTIVELY PHOTOMORPHOGENIC 1),VvHY5(ELONGATED HYPOCOTYL5),VvHYH(HY5 HOMOLOG),VvELIP(early light-induced protein)and VvPIF3(PHYTOCHROME INTERACTING FACTOR 3)may play important roles in this shoot-to-root signaling.Furthermore,the correlation network between differential expression genes and physiological traits indicated that VvpsbS(photosystem II subunit S),Vvpsb28(photosystem II subunit 28),VvHYH,VvSUS4(sucrose synthase 4),and VvALDA(fructose-bisphosphate aldolase)were pertinent candidate genes in responses to different light qualities.Our results provide a foundation for optimizing the light recipe of grape plantlets and strengthen the understanding of light signaling and carbon metabolism under different monochromatic lights.

Anthocyanins are essential for the quality of perennial horticultural crops,such as grapes.In grapes,ELONGATED HYPOCOTYL 5(HY5)and MYBA1 are two critical transcription factors that regulate anthocyanin biosynthesis.Our previous work has shown that Vitis vinifera B-box protein 44(VvBBX44)inhibits anthocyanin synthesis and represses VvHY5 expression in grape calli.However,the regulatory mechanism underlying this regulation was unclear.In this study,we found that loss of VvBBX44 function resulted in increased anthocyanin accumulation in grapevine callus.VvBBX44 directly represses VvMYBA1,which activates VvBBX44.VvMYBA1,but not VvBBX44,directly modulates the expression of grape UDP flavonoid 3-O-glucosyltransferase(VvUFGT).We demonstrated that VvBBX44 represses the transcriptional activation of VvUFGT and VvBBX44 induced by VvMYBA1.However,VvBBX44 and VvMYBA1 did not physically interact in yeast.The application of exogenous anthocyanin stimulated VvBBX44 expression in grapevine suspension cells and tobacco leaves.These findings suggest that VvBBX44 and VvMYBA1 form a transcriptional feedback loop to prevent overaccumulation of anthocyanin and reduce metabolic costs.Our work sheds light on the complex regulatory network that controls anthocyanin biosynthesis in grapevine.
