The phytohormones ethylene(ET)and jasmonate(JA)regulate plant development,growth,and defense responses;however,the molecular basis for their signaling crosstalk is unclear.Here,we show that JA-ZIM-domain(JAZ)proteins,which repress JA signaling,repress trichome initiation/branching and anthocyanin accumulation,and inhibit the transcriptional activity of the basic helix-loop-helix(bHLH)-MYBmembers(GLABRA3(GL3)-GL1 and TRANSPARENT TESTA 8(TT8)-MYB75)of WD-repeat/bHLH/MYB(WBM)complexes.The ET-stabilized transcription factors ETHYLENEINSENSITIVE3(EIN3)and EIN3-LIKE1(EIL1)were found to bind to several members of WBM complexes,including GL3,ENHANCER OF GLABRA3(EGL3),TT8,GL1,MYB75,and TRANSPARENT TESTA GLABRA1(TTG1).This binding repressed the transcriptional activity of the b HLH-MYB proteins and inhibited anthocyanin accumulation,trichome formation,and defenses against insect herbivores while promoting root hair formation.Conversely,the JA-activated b HLH members GL3,EGL3,and TT8 of WBM complexes were able to interact with and attenuate the transcriptional activity of EIN3/EIL1 at the HOOKLESS1 promoter,and their overexpression inhibited apical hook formation.Thus,this study demonstrates a molecular framework for signaling crosstalk between JA and ET in plant development,secondary metabolism,and defense responses.

To understand the anthocyanin characteristics of wine grape varieties,the anthocyanin composition and content of 31 wine grape varieties were analyzed to explore the use of anthocyanins as chemical fingerprints to distinguish varieties.Results showed that a total of 21 anthocyanins were detected in the skins,including cyanidin,delphinidin,petunidin,peonidin and malvidin 3-monoglucosides(or 3,5-diglucosides)along with the corresponding acetyl and p-coumaroyl derivatives.The highest and lowest total amount of anthocyanins were detected in‘Ruby Cabernet’and‘Muscat Rouge’,respectively.In the 21 Vitis vinifera grapes,there were 3~11 monoglucoside anthocyanins detected,however,there were 4 to 9 monoglucoside anthocyanins and 1~7 diglucoside anthocyanins detected in the 10 other species of grapes.Except for‘Zhesexiang’‘Seibel Noir’,‘44-6-7-1’and‘Beibinghong’,the contents of diglucoside anthocyanins in the other six varieties accounted for more than 52%of the total anthocyanins.Except for‘Zhesexiang’,‘Muscat Rouge’and‘Beibinghong’,the content of methylated anthocyanins accounted for more than 75%of total anthocyanins.There were significant differences in the anthocyanin types and contents in the skins among V.vinifera and other grapes.The results of the principal component analysis and the cluster classification of 31 grape varieties(lines)were nearly consistent,which suggested that anthocyanins can be used as chemical fingerprints to distinguish wine grape varieties.

Spine grape(Vitis davidii Foex.)is an important wild grape species native to China.Fifteen red spine grape clones and three red Vitis vinifera grape varieties were used to evaluate the differences in the anthocyanin profiles and color properties of wines made from V.davidii and V.vinifera grapes.Among spine wines,‘Junzi#2’wine had the highest total phenolic and total anthocyanin,‘Xiangzhenzhu’wine had the highest total flavonoids,and‘Junzi#1’wine had the highest total tannin.The anthocyanin compositions of all of the spine wines were dominated by Mv-3,5-diglucoside.The total individual anthocyanin contents in spine wines,except‘Gaoshan#5’,‘Junzi#5055’,‘Junzi#5061’,and‘Junzi#5044’,were signifi cantly higher than in V.vinifera wines.Most of the spine wines had a stronger red intensity and a brighter chroma with a bluer hue than V.vinifera wines.Correlation analysis revealed that the color properties were closely related to the anthocyanin composition.These results suggest that wines made from spine grapes may be useful for the wine industry for their color properties and high individual anthocyanin contents.

anthocyanin can arrest the cone photoreceptor degeneration and act as a novel treatment for retinitis pigmentosa

引用

International Journal of Ophthalmology(English edition) 2016年第1期9卷 153-158页

Retinitis pigmentosa（RP）is a group of heterogeneous inherited retinal diseases that is characterized by primary death rod photoreceptors and the secondary loss of cones.The degeneration of cones causes gradual constriction of visual fields,leaving the central islands that are eventually snuffed out.Studies indicate that the hyperoxia causes oxidative damage in the retina and contributes to the cone death of RP.Moreover,abundant reactive oxidative species（ROS）which are generated in cones may result in mitochondria membrane depolarization,which has been ascribed a central role in the apoptotic process and has been proposed to act as a forward feeding loop for the activation of downstream cascades.anthocyanin is a potent antioxidant which has been evidenced to be able to counteract oxidative damages,scavenge surplus ROS,and rectify abnormities in the apoptotic cascade.Taken together with its ability to attenuate inflammation which also contributes to the etiology of RP,it is reasonable to hypothesize that the anthocyanin could act as a novel therapeutic strategy to retard or prevent cone degeneration in RP retinas,particularly if the treatment is timed appropriately and delivered efficiently.Future pharmacological investigations will identify the anthocyanin as an effective candidate for PR therapy and refinements of that knowledge would ignite the hope of restoring the visual function in RP patients.

The Asiatic hybrid lily(Lilium spp.)is a horticultural crop with high commercial value and diverse anthocyanin pigmentation patterns.However,the regulatory mechanism underlying lily flower color has been largely unexplored.Here,we identified a WRKY transcription factor from lily tepals,LhWRKY44,whose expression was closely associated with anthocyanin accumulation.Functional verification indicated that LhWRKY44 positively regulated anthocyanin accumulation.LhWRKY44 physically interacted with LhMYBSPLATTER and directly bound to the LhMYBSPLATTER promoter,which enhanced the effect of the LhMYBSPLATTER-LhbHLH2 MBW complex activator on anthocyanin accumulation.Moreover,EMSA and dual-luciferase assays revealed that LhWRKY44 activated and bound to the promoters of gene LhF3H and the intracellular anthocyanin-related glutathione S-transferase gene LhGST.Interestingly,our further results showed that LhWRKY44 participated in light and drought-induced anthocyanin accumulation,and improved the drought tolerance in lily via activating stress-related genes.These results generated a multifaceted regulatory mechanism for the LhWRKY44-meditaed enhancement by the environmental signal pathway of anthocyanin accumulation and expanded our understanding of the WRKY-mediated transcriptional regulatory hierarchy modulating anthocyanin accumulation in Asiatic hybrid lilies.

Cerasus humilis is a kind of economic fruit tree peculiar to China,which is widely used in the food,landscape,and pharmaceutical industries.anthocyanins are a phenolic metabolite that plays an essential role in fruit coloration.However,the regulatory network of C.humilis in anthocyanin biosynthesis is still unclear.In this study,the R2R3-MYB transcription factor ChMYB1 was isolated from the full genome of the species.Yeast one-hybrid,dual-luciferase assays,and GUS staining showed that ChMYB1 significantly increased anthocyanin contents in C.humilis fruit by promoting the expression of ChCHS and ChUFGT by binding MBS(MYB-binding elements).ChMYB1 interacted with ChbHLH42and ChTTG1 to form the MBW complex and further enhanced the expression of ChUFGT.In addition,abscisic acid(ABA)treatment promoted the expression of ChMYB1 and anthocyanin accumulation in C.humilis fruit.Interestingly,ABA treatment enhanced the interaction between ChMYB1 and ChbHLH42.Furthermore,ChABI5 inhibited the interaction between ChMYB1 and ChbHLH42.Our data elucidated the primary molecular mechanism of anthocyanin biosynthesis in C.humilis fruit,deepening the understanding of the regulatory network affecting anthocyanin metabolism in edible fruit crops.

Yellow seed trait is a desirable characteristic with potential for increasing seed quality and commercial value in rapeseed,and anthocyanin and proanthocyanidins(PAs)are major seed-coat pigments.Few transcription factors involved in the regulation of anthocyanin and PAs biosynthesis have been characterized in rapeseed.In this study,we identified a transcription factor gene BnbHLH92a(BnaA06T0441000ZS)in rapeseed.Overexpressing BnbHLH92a both in Arabidopsis and in rapeseed reduced levels of anthocyanin and PAs.Correspondingly,the expression profiles of anthocyanin and PA biosynthesis genes(TT3,BAN,TT8,TT18,and TTG1)were shown by quantitative real-time PCR to be inhibited in BnbHLH92a-overexpressing Arabidopsis seeds,indicating that BnbHLH92a represses the anthocyanin and PA biosynthesis pathway in Arabidopsis.BnbHLH92a physically interacts with the BnTTG1 protein and represses the biosynthesis of anthocyanins and PAs in rapeseed.BnbHLH92a also binds directly to the BnTT18 promoter and represses its expression.These results suggest that BnbHLH92a is a novel upstream regulator of flavonoid biosynthesis in B.napus.

Aims anthocyanin accumulation is the main factor underlying why young plant leaves turn red,and plant growth follows the principle of maximizing the economic efficiency of energy.There is a need to verify the role of young plant leaves turning red and confirm whether anthocyanin accumulation overconsumes the energy of the plant.Methods We compared the different pigment contents,antioxidant capaci-ties,leaf mass per area,photosynthetic characteristics,dark res-piration rates,light compensation points(LCPs)and electron flow distribution of young and mature Schima superba leaves grown under full sunlight and 30%full sunlight conditions.We then exam-ined the correlations between anthocyanins and total antioxidant capacity,photosynthetic pigments,dark respiration rates,LCPs by using linear regression.Finally,we analyzed Pearson correlation coefficients and used principal component analysis to evaluate the interactions of these functional indicators.Important Findings The young leaves of S.superba accumulated anthocyanins in full sunlight but not in 30%full sunlight.anthocyanins substantially con-tributed to the total antioxidant capacity(accounting for 33.29%)in juvenile S.superba leaves.Young leaves containing more anthocyanin accumulated less reactive oxygen species after high light(HL)treat-ment.However,juvenile leaves accumulating anthocyanins showed 56.97%higher dark respiration rates,24.79%higher LCPs and 5.32%higher allocations of electron flow to photorespiration and lower organic substance accumulation than did those without anthocyanins.These results suggest that young S.superba leaves must consume more energy to accumulate anthocyanins to adapt to HL environments.Therefore,plants sacrifice growth rate to ensure survival,which is a trade-off for their ability to respond to external environments.
