| 1 | MdGSTF6,activated by MdMYB1,plays an essential role in anthocyanin accumulation in apple显示文摘Anthocyanins are biosynthesized on the cytosolic surface of the endoplasmic reticulum and then transported into the vacuole for storage.Glutathione S-transferases(GSTs)are considered to be responsible for the transport of anthocyanins into the vacuole.However,the regulatory mechanisms of GSTs in plants are still unclear.Here,we performed a genome-wide analysis and identified 69 GST genes in apple.The expression of MdGSTF6 was positively correlated with the anthocyanin content(r=0.949)during‘Yanfu 8’fruit development.The overexpression of MdGSTF6 in the Arabidopsis thaliana tt19 mutant resulted in seedlings of 35S::MdGSTF6-GFP/tt19 that could accumulate anthocyanin and rescue its phenotype,suggesting that MdGSTF6 was an anthocyanin transporter.The silencing of MdGSTF6 affected anthocyanin accumulation in apple fruit.Moreover,the knockdown of MdGSTF6 by RNA interference in cultured‘Gala’seedlings inhibited anthocyanin accumulation.The interaction experiments showed that MdMYB1 could bind directly to the MdGSTF6 promoter to transcriptionally activate its expression.Collectively,our results demonstrate that MdGSTF6 encodes an important GST transporter of anthocyanins in apple fruit and provide evidence for the associated regulatory mechanisms.Therefore,MdMYB1 can not only regulate anthocyanin synthesis,but also control the transport of anthocyanin in apples.This information may be useful for further clarifying the regulation of anthocyanin transport in apple. | Shenghui Jiang Min Chen Naibo He Xiaoliu Chen Nan Wang Qingguo Sun Tianliang Zhang Haifeng Xu Hongcheng Fang Yicheng Wang Zongying Zhang Shujing Wu Xuesen Chen | 2019 | Horticulture Research2019，6，1： | 16 |
| 2 | Malus sieversii: the origin, flavonoid synthesis mechanism, and breeding of red-skinned and red-fleshed apples显示文摘Flavonoids play essential roles in human health.Apple(Malus domestica Borkh.),one of the most widely produced and economically important fruit crops in temperate regions,is a significant source of flavonoids in the human diet and is among the top nutritionally rated and most widely consumed fruits worldwide.Epidemiological studies have shown that the consumption of apples,which are rich in a variety of free and easily absorbable flavonoids,is associated with a decreased risk of various diseases.However,apple production is challenged by serious inbreeding problems.The narrowing of the hereditary base has resulted in apples with poor nutritional quality and low flavonoid contents.Recently,there have been advances in our understanding of the roles that Malus sieversii(Ledeb.)M.Roem has played in the process of apple domestication and breeding.In this study,we review the origin of cultivated apples and red-fleshed apples,and discuss the genetic diversity and construction of the core collections of M.sieversii.We also discuss current research progress and breeding programs on red-skinned and red-fleshed apples and summarize the exploitation and utilization of M.sieversii in the breeding of high-flavonoid,and red-fleshed apples.This study highlights a valuable pattern of horticultural crop breeding using wild germplasm resources.The future challenges and directions of research on the molecular mechanisms of flavonoid accumulation and high-flavonoid apple breeding are discussed. | Nan Wang Shenghui Jiang Zongying Zhang Hongcheng Fang Haifeng Xu Yicheng Wang Xuesen Chen | 2018 | Horticulture Research2018，5，1： | 15 |
| 3 | Effect of the distributor plugging ways on fluidization quality and particle stratification in air dense medium fluidized bed显示文摘Gas-solid fluidized bed separation is a highly efficient and clean technique for coal separation,and can effectively remove ash and sulfur contained gangue minerals from coal.However,the fine coal plugging distributor often leads to uneven fluidization and affects the separation effect.In this paper,different plugging ways were designed to study their effects on the fluidization characteristics and particle mixing.It was found that when the plugging phenomenon occurs,the minimum fluidization velocity of the fluidized bed gradually decreases as the plugging area enlarges.The difference between the top and the bottom of the bed minimum fluidization velocity increases accordingly,and a“stagnation phenomenon”occurs in the bed.The standard deviation of pressure fluctuations at the top of the bed is smaller than that at the bottom of the bed,which is the opposite of normal conditions.As the area of the plugging increases,the dead zone on the side wall of the fluidized bed significantly increases.The size of the dead zone is rapid reducing at the initial stage.It was noticed that the stratification of the low-density products is particularly affected by plugging,whereas the stratification of high-density products is not obviously influenced by certain conditions. | Zhonglin Gao Xuesen Chai Enhui Zhou Ying Jia Chenlong Duan Ligang Tang | 2020 | International Journal of Mining Science and Technology2020，30，6： | 7 |
| 4 | Effects of Soil Texture on the Growth of Young Apple Trees and Soil Microbial Community Structure Under Replanted Conditions显示文摘A two-year field experiment was carried out in order to study the occurrence degree and mechanism of apple replant disease(ARD)in the apple orchards with different soil textures.So we can adopt appropriate controlmeasures according to the severity of ARD.Healthy two-year-old seedlings with consistent growth were selected,of which the root stock was T337 and the scion was Yanfu 3.There were significant differences in biomass between methyl bromide fumigation and replanted treatments,and the difference was the largest in clay loam,followed by sandy loam,and loam,which verified ARD in clay loam was most serious,followed by sandy loam and loam.Based on high-throughput sequencing of fungi in soil samples,fungal richness and diversity were the highest in clay loam,followed by sandy loam,and loam.The relative abundance of Fusarium in SX,SL,FX,FL,WX and WL was 7.33%,19.32%,2.70%,4.24%,10.71%and 23.87%,respectively.Based on Real-time quantitative analysis,there were significant differences in the number of Fusarium oxysporum and Fusarium solani between methyl bromide fumigation and replanted treatments,i.e.,clay loam>sandy loam>loam.Fusarium was the main pathogen causing ARD.This shows that ARD is the most serious under replanted clay loam condition.High-throughput sequencing technology was used to prove the difference in Fusarium was one of the important reasons for ARD under different soil textures.This technology provides a new idea for the prevention and control of ARD. | Yuefan Sheng Haiyan Wang MeiWang Hanhao Li Li Xiang Fengbing Pan Xuesen Chen Xiang Shen Chengmiao Yin Zhiquan Mao | 2020 | Horticultural Plant Journal2020，6，3： | 7 |
| 5 | MdMYB6 regulates anthocyanin formation in apple both through direct inhibition of the biosynthesis pathway and through substrate removal显示文摘Anthocyanin biosynthesis and sugar metabolism are important processes during plant growth,but the molecular interactions underlying these pathways are still unclear.In this work,we analyzed the anthocyanin and soluble sugar contents,as well as the transcript levels of transcription factors that are known to be related to the biosynthesis of anthocyanin in‘Hongcui 1’apple flesh during fruit development.Overexpression of MdMYB6 in red-fleshed calli was found to reduce anthocyanin content and result in downregulated expression of the MdANS and MdGSTF12 proteins.Yeast one-hybrid and electrophoretic mobility shift analyses showed that MdMYB6 could directly bind to the promoters of MdANS and MdGSTF12,indicating that MdMYB6 could inhibit anthocyanin biosynthesis by regulating MdANS and MdGSTF12.Overexpression of MdTMT1 in the Arabidopsis tmt1 mutant restored the glucose and fructose contents to the wild-type levels,while overexpression of MdTMT1 in red-fleshed calli increased the contents of glucose and fructose but reduced the contents of UDP-glucose,UDP-galactose,and anthocyanin.Using a GUS reporter system,yeast one-hybrid,chromatin immunoprecipitation-PCR and electrophoretic mobility shift analyses,we found that MdMYB6 could bind to the promoter of MdTMT1,resulting in increased promoter activity.Overexpression of MdMYB6 in calli overexpressing MdTMT1 increased the expression of MdTMT1,which led to reduced contents of UDP-glucose and UDP-galactose and decreased anthocyanin content compared to those of the calli that overexpressed MdTMT1.This finding suggested that MdMYB6 could also inhibit anthocyanin biosynthesis by regulating MdTMT1 to decrease the contents of UDP-glucose and UDP-galactose.Taken together,these results showed that MdMYB6 and MdTMT1 play key roles in both anthocyanin biosynthesis and sugar transport. | Haifeng Xu Qi Zou Guanxian Yang Shenghui Jiang Hongcheng Fang Yicheng Wang Jing Zhang Zongying Zhang Nan Wang Xuesen Chen | 2020 | Horticulture Research2020，7，1： | 6 |
| 6 | Exogenous Melatonin Improves Physiological Characteristics and Promotes Growth of Strawberry Seedlings Under Cadmium Stress显示文摘Melatonin,as a plant growth regulator,is involved in plant stress resistance.We studied the effects of different concentrations(0,10,50,100,150,and 200μmol·L−1)of melatonin on the growth and physiological characteristics of strawberry under cadmium(Cd)stress.The results represented that the growth of strawberry seedlings was inhibited under Cd stress,and the seedling biomass,chlorophyll content and the activities of antioxidant enzymes such as superoxide dismutase(SOD),peroxidase(POD),catalase(CAT),and ascorbate peroxidase(APX)decreased.These toxic effects were,however,effectively remediated by exogenous melatonin pretreatment.Melatonin treatment slowed the inhibitory effect of seedling growth and significantly increased seedling biomass,chlorophyll content,antioxidant enzyme activities,and soluble protein levels in leaves and roots compared with the control.Melatonin treatment also reduced the malondialdehyde(MDA)content and the oxidative stress reactions,increased the anthocyanin content,and slowed the senescence rate,thereby reducing the toxic effects of Cd on strawberries.This indicates that foliar application of melatonin can effectively remediate the adverse effects of Cd on strawberry seedlings;the greatest effect was obtained with melatonin concentration of 100μmol·L−1. | Shuqing Wu Yao Wang Junkang Zhang Xiaojun Gong Zhen Zhang Jingjing Sun Xuesen Chen Yanling Wang | 2021 | Horticultural Plant Journal2021，7，1： | 6 |
| 7 | Therapeutic strategies for a functional cure of chronic hepatitis B virus infection显示文摘Treatment of chronic hepatitis B virus(HBV)infection with the viral DNA polymerase inhibitors or pegylated alpha-interferon has led to a significant retardation in HBV-related disease progression and reduction in mortality related to chronic hepatitis B associated liver decompensation and hepatocellular carcinoma.However,chronic HBV infection remains not cured.The reasons for the failure to eradicate HBV infection by long-term antiviral therapy are not completely understood.However,clinical studies suggest that the intrinsic stability of the nuclear form of viral genome,the covalently closed circular(ccc)DNA,sustained low level viral replication under antiviral therapy and homeostatic proliferation of hepatocytes are the critical virological and pathophysiological factors that affect the persistence and therapeutic outcomes of HBV infection.More importantly,despite potent suppression of HBV replication in livers of the treated patients,the dysfunction of HBV-specific antiviral immunity persists.The inability of the immune system to recognize cells harboring HBV infection and to cure or eliminate cells actively producing virus is the biggest challenge to finding a cure.Unraveling the complex virus–host interactions that lead to persistent infection should facilitate the rational design of antivirals and immunotherapeutics to cure chronic HBV infection. | Jinhong Chang Fang Guo Xuesen Zhao Ju-Tao Guo | 2014 | Acta Pharmaceutica Sinica B2014，4，4： | 5 |
| 8 | New prevalence estimate of Torque Teno virus(TTV) infection in healthy population and patients with chronic viral hepatitis in Jiujiang, China显示文摘Dear Editor,Torque Teno virus(TTV)is a nonenveloped human DNA virus that was isolated from the serum of a patient with transfusion-transmitted hepatitis with unknown etiology in 1997(Nishizawa et al.,1997).TTV is the first human virus with a single-stranded circular DNA genome to be identified,and is recently classified as the Alphatorquevirus genus of the Anelloviridae family by the International Committee on Taxonomy of Viruses(ICTV)(King et al.,2011).TTV shows very high | Jin Peng Yueyue Fang Xuesen Zhao Yihong Peng | 2015 | Virologica Sinica2015，30，3： | 4 |
| 9 | Activation of disease resistance against Botryosphaeria dothidea by downregulating the expression of MdSYP121 in apple显示文摘In plants,the vesicle fusion process plays a vital role in pathogen defence.However,the importance of the vesicle fusion process in apple ring rot has not been studied.Here,we isolated and characterised the apple syntaxin gene MdSYP121.Silencing the MdSYP121 gene in transgenic apple calli increased tolerance to Botryosphaeria dothidea infection;this increased tolerance was correlated with salicylic acid(SA)synthesis-related and signalling-related gene transcription.In contrast,overexpressing MdSYP121 in apple calli resulted in the opposite phenotypes.In addition,the results of RNA sequencing(RNA-Seq)and quantitative real-time PCR(qRT-PCR)assays suggested that MdSYP121 plays an important role in responses to oxidation–reduction reactions.Silencing MdSYP121 in apple calli enhanced the expression levels of reactive oxygen species(ROS)-related genes and the activity of ROS-related enzymes.The enhanced defence response status in MdSYP121-RNAi lines suggests that syntaxins are involved in the defence response to B.dothidea.More importantly,we showed that MdSYP121 forms a soluble N-ethylmaleimide-sensitive factor attachment protein receptor(SNARE)complex with MdSNAP33,and the complex may participate in regulating resistance to B.dothidea.In conclusion,by regulating the interaction of SA pathway and oxidation–reduction process,MdSYP121 can influence the pathogen infection process in apple. | Xiaowen He Yanhong Huo Xiuxia Liu Qianqian Zhou Shouqian Feng Xiang Shen Baohua Li Shujing Wu Xuesen Chen | 2018 | Horticulture Research2018，5，1： | 3 |

| 11 | High reproducibility and sensitivity of bifacial copper nanowire array for detection of glucose显示文摘The ordered bifacial copper nanowire array(Cu BNWA) was synthesized by a template assisted electrochemical deposition method.The morphology and structure of the as-prepared samples were investigated by field emission scanning electron microscope(FESEM) and X-ray diffraction(XRD).The results show that the ordered Cu nanowire array with uniform geometrical dimensions covered both side of the Cu substrate.When used as the electrode for glucose detection,the minimum detectable concentration of glucose can be reached as low as 0.2 mM.Impressively,the sample still showed high sensitivity and stability for glucose detection after two months placement in ambient environment.These excellent performances of the Cu BNWA make it a promising non-enzyme glucose detection sensor for various applications. | Hanqing Zhang Yining Wang Xuesen Gao Zhuo Gao Yan Chen | 2017 | Progress in Natural Science:Materials International2017，27，3： | 2 |

| 13 | Corilagin inhibits SARS-CoV-2 replication by targeting viral RNA-dependent RNA polymerase显示文摘Severe acute respiratory syndrome coronavirus-2(SARS-CoV-2) has become one major threat to human population health.The RNA-dependent RNA polymerase(RdRp) presents an ideal target of antivirals,whereas nucleoside analogs inhibitor is hindered by the proofreading activity of coronavirus.Herein,we report that corilagin(RAI-S-37) as a non-nucleoside inhibitor of SARS-CoV-2 RdRp,binds directly to RdRp,effectively inhibits the polymerase activity in both cell-free and cell-based assays,fully resists the proofreading activity and potently inhibits SARS-CoV-2 infection with a low 50% effective concentration(EC50) value of 0.13 μmol/L.Computation modeling predicts that RAI-S-37 lands at the palm domain of RdRp and prevents conformational changes required for nucleotide incorporation by RdRp.In addition,combination of RAI-S-37 with remdesivir exhibits additive activity against antiSARS-CoV-2 RdRp.Together with the current data available on the safety and pharmacokinetics of corilagin as a medicinal herbal agent,these results demonstrate the potential of being developed into one of the much-needed SARS-CoV-2 therapeutics. | Quanjie Li Dongrong Yi Xiaobo Lei Jianyuan Zhao Yongxin Zhang Xiangling Cui Xia Xiao Tao Jiao Xiaojing Dong Xuesen Zhao Hui Zeng Chen Liang Lili Ren Fei Guo Xiaoyu Li Jianwei Wang Shan Cen | 2021 | Acta Pharmaceutica Sinica B2021，11，6： | 2 |
| 14 | Development of potent promoters that drive the efficient expression of genes in apple protoplasts显示文摘Protoplast transient expression is a powerful strategy for gene functional characterization,especially in biochemical mechanism studies.We herein developed a highly efficient transient expression system for apple protoplasts.The abilities of the Arabidopsis thaliana and Malus domestica ubiquitin-10(AtUBQ10 and MdUBQ10)promoters to drive the expression of multiple genes were compared with that of the CaMV 35S promoter,and the results revealed that the AtUBQ10 and MdUBQ10 promoters were more efficient in apple protoplasts.With this system,we demonstrated that active AtMKK7ac could activate MAPK6/3/4 signaling cascades,which further regulated MdWRKY33 phosphorylation and stability in apple.Furthermore,the ligand-induced interaction between the immune receptor AtFLS2 and the coreceptor AtBAK1 was reconstituted in apple protoplasts.We also found that the stability of the bacterial effector AvrRpt2 was regulated by feedback involving auxin and the immune regulator RIN4.The system established herein will serve as a useful tool for the molecular and biochemical analyses of apple genes. | Xianpu Wang Lili Xu Xiuxia Liu Li Xin Shujing Wu Xuesen Chen | 2021 | Horticulture Research2021，8，1： | 2 |
