| 1 | Bacillus amyloliquefaciens Strain W19 can Promote Growth and Yield and Suppress Fusarium Wilt in Banana Under Greenhouse and Field Conditions显示文摘Plant growth-promoting rhizobacteria(PGPR) are considered to be the most promising agents for cash crop production via increasing crop yields and decreasing disease occurrence. The Bacillus amyloliquefaciens strain W19 can produce secondary metabolites(iturin and bacillomycin D) effectively against Fusarium oxysporum f. sp. cubense(FOC). In this study, the ability of a bio-organic fertilizer(BIO) containing strain W19 to promote plant growth and suppress the Fusarium wilt of banana was evaluated in both pot and field experiments. The results showed that application of BIO significantly promoted the growth and fruit yield of banana while suppressing the banana Fusarium wilt disease. To further determine the beneficial mechanisms of the strain, the colonization of green fluorescent protein-tagged strain W19 on banana roots was observed using confocal laser scanning microscopy and scanning electron microscopy. The effect of banana root exudates on the formation of biofilm of strain W19 indicated that the banana root exudates may enhance colonization. In addition, the strain W19 was able to produce indole-3-acetic acid(IAA), a plant growth-promoting hormone.The results of these experiments revealed that the application of strain W19-enriched BIO improved the banana root colonization of strain W19 and growth of banana and suppressed the Fusarium wilt. The PGPR strain W19 can be a useful biocontrol agent for the production of banana under field conditions. | WANG Beibei SHEN Zongzhuan ZHANG Fengge Waseem RAZA YUAN Jun HUANG Rong RUAN Yunze LI Rong SHEN Qirong | 2016 | Pedosphere2016，26，5： | 22 |
| 2 | Methane and nitrous oxide concentration and emission flux of Yangtze Delta plain river net显示文摘Methane (CH4) and nitrous oxide (N2O) saturation concentration and gas-water interface emission flux in surface water of the Yangtze Delta plain river net were investigated in summer at representative sites including the upper reaches of the Huangpu River and the rivers in the Chongming Island. The results show that the CH4 concentration in river water ranged from 0.30±0.03 to 6.66±0.14 μmol.L-1, and N2O concentration ranged from 13.8±2.33 to 435±116 nmol.L-1. River surface water had a very high satura- tion level of CH4 (from 468±49.0% to 11560±235%) and that of N2O (from 175±29.5% to 4914±1304%). Dissolved oxygen (DO) was the primary factor controlling the CH4 concentration in water. N2O concentration had significant negative correlation with salinity and a significant positive correlation with nitrate (NO3-), nitrite (NO2-), chemical oxygen demand (CODcr) concentration and pH of river water. CH4 and N2O of river water were brought about mainly by methanogenesis and denitrification in river bottom sediment that diffused through sediment-water interface into the water body and then into atmosphere through the gas-water interface. The emission flux of CH4 and N2O at river gas-water interface reached 778±59.8 and 236±63.6 μmol.m-2.h-1, respectively in summer. The river net was a potential source of atmospheric CH4 and N2O because of eutrophication of the water body. | WANG DongQi CHEN ZhenLou SUN WeiWei HU BeiBei XU ShiYuan | 2009 | Science China Chemistry2009，52，5： | 19 |
| 3 | Photonic circuits written by femtosecond laser in glass:improved fabrication and recent progress in photonic devices显示文摘Integrated photonics is attracting considerable attention and has found many applications in both classical and quantum optics,fulfilling the requirements for the ever-growing complexity in modern optical experiments and big data communication.Femtosecond(fs)laser direct writing(FLDW)is an acknowledged technique for producing waveguides(WGs)in transparent glass that have been used to construct complex integrated photonic devices.FLDW possesses unique features,such as three-dimensional fabrication geometry,rapid prototyping,and single step fabrication,which are important for integrated communication devices and quantum photonic and astrophotonic technologies.To fully take advantage of FLDW,considerable efforts have been made to produce WGs over a large depth with low propagation loss,coupling loss,bend loss,and highly symmetrical mode field.We summarize the improved techniques as well as the mechanisms for writing high-performance WGs with controllable morphology of cross-section,highly symmetrical mode field,low loss,and high processing uniformity and efficiency,and discuss the recent progress of WGs in photonic integrated devices for communication,topological physics,quantum information processing,and astrophotonics.Prospective challenges and future research directions in this field are also pointed out. | Dezhi Tan Zhuo Wang Beibei Xu Jianrong Qiu | 2021 | Advanced Photonics2021，3，2： | 19 |
| 4 | Spectral tomographic imaging with aplanatic metalens显示文摘Tomography is an informative imaging modality that is usually implemented by mechanical scanning,owing to the limited depth-of-field(DOF)in conventional systems.However,recent imaging systems are working towards more compact and stable architectures;therefore,developing nonmotion tomography is highly desirable.Here,we propose a metalens-based spectral imaging system with an aplanatic GaN metalens(NA=0.78),in which large chromatic dispersion is used to access spectral focus tuning and optical zooming in the visible spectrum.After the function of wavelength-switched tomography was confirmed on cascaded samples,this aplanatic metalens is utilized to image microscopic frog egg cells and shows excellent tomographic images with distinct DOF features of the cell membrane and nucleus.Our approach makes good use of the large diffractive dispersion of the metalens and develops a new imaging technique that advances recent informative optical devices. | Chen Chen Wange Song Jia-Wern Chen Jung-Hsi Wang Yu Han Chen Beibei Xu Mu-Ku Chen Hanmeng Li Bin Fang Ji Chen Hsin Yu Kuo Shuming Wang Din Ping Tsai Shining Zhu Tao Li | 2019 | Light(Science & Applications)2019，8，1： | 12 |
| 5 | Synthesis of bifunctional Pt/MgAPO-5 catalysts and their catalytic performance in the hydrogenation of nitrobenzene to p-aminophenol显示文摘MgAPO-5 molecular sieves have been synthesized using diethylaminoethanol as the templating agent in a wide range of the MgO/Al2O3 ratio.The samples were characterized by XRD,SEM,solid state NMR,FT-IR and NH3-TPD.Using MgAPO-5 as acidic supports,bifunctional Pt/MgAPO-5 catalysts were prepared for hydrogenation of nitrobenzene to p-aminophenol (PAP).The results showed that the MgO/Al2O3 ratios influenced the Mg content and the acidity of MgAPO-5 samples,thereby greatly affecting the catalytic performance of Pt/MgAPO-5 catalysts.The selectivity to PAP over Pt/MgAPO-5 was dependent on the amount of strong acid sites of MgAPO-5.When the MgO/Al2O3 molar ratio was 0.5,the synthesized MgAPO-5 sample exhibited the largest amount of strong acid and a highest PAP yield of 41.1% was achieved over Pt/MgAPO-5 catalyst. | ShuFang Wang YaDan Jin BeiBei He YanJi Wang XinQiang Zhao | 2010 | Science China Chemistry2010，53，7： | 9 |
| 6 | Emerging low-nuclearity supported metal catalysts with atomic level precision for efficient heterogeneous catalysis显示文摘Supported atomically dispersed metal catalysts(ADMCs)have received enormous attention due to their high atom utilization efficiency,mass activity and excellent selectivity.Single-atom site catalysts(SACs)with monometal-center as the quintessential ADMCs have been extensively studied in the catalysis-related fields.Beyond SACs,novel atomically dispersed metal catalysts(NADMCs)with flexible active sites featuring two or more catalytically centers including dual-atom and triple-atom catalysts have drawn ever-increasing attention recently.Owing to the presence of multiple neighboring active sites,NADMCs could exhibit much higher activity and selectivity compared with SACs,especially in those complicated reactions with multi-step intermediates.This review comprehensively outlines the recent exciting advances on the NADMCs with emphasis on the deeper understanding of the synergistic interactions among multiple metal atoms and underlying structure-performance relationships.It starts with the systematical introduction of principal synthetic approaches for NADMCs highlighting the key issues of each fabrication method including the atomically precise control in the design of metal nuclearity,and then the state-of-the-art characterizations for identifying and monitoring the atomic structure of NADMCs are explored.Thereafter,the recent development of NADMCs in energy-related applications is systematically discussed.Finally,we provide some new insights into the remaining challenges and opportunities for the development of NADMCs. | Xiaobo Zheng Beibei Li Qishun Wang Dingsheng Wang Yadong Li | 2022 | Nano Research2022，15，9： | 9 |
| 7 | Graphitic carbon nitride/biochar composite synthesized by a facile ball-milling method for the adsorption and photocatalytic degradation of enrofloxacin显示文摘In order to enhance the removal performance of graphitic carbon nitride(g-C_(3)N_(4)) on organic pollutant, a simultaneous process of adsorption and photocatalysis was achieved via the compounding of biochar and g-C_(3)N_(4). In this study, g-C_(3)N_(4) was obtained by a condensation reaction of melamine at 550 °C. Then the g-C_(3)N_(4)/biochar composites were synthesized by ball milling biochar and g-C_(3)N_(4) together, which was considered as a simple, economical, and green strategy. The characterization of resulting g-C_(3)N_(4)/biochar suggested that biochar and g-C_(3)N_(4) achieved effective linkage. The adsorption and photocatalytic performance of the composites were evaluated with enrofloxacin(EFA) as a model pollutant. The result showed that all the g-C_(3)N_(4)/biochar composites displayed higher adsorption and photocatalytic performance to EFA than that of pure g-C_(3)N_(4). The 50% g-C_(3)N_(4)/biochar performed best and removed 45.2% and 81.1% of EFA(10 mg/L) under darkness and light with a dosage of 1 mg/mL, while g-C_(3)N_(4) were 19.0% and 27.3%, respectively. Besides, 50% g-C_(3)N_(4)/biochar showed the highest total organic carbon(TOC) removal efficiency(65.9%). Radical trapping experiments suggested that superoxide radical( ·O_(2)^(-)) and hole(h~+) were the main active species in the photocatalytic process. After 4 cycles, the composite still exhibited activity for catalytic removal of EFA. | Yao Xiao Honghong Lyu Chengliang Yang Beibei Zhao Lan Wang Jingchun Tang | 2021 | Journal of Environmental Sciences2021，33，5： | 8 |

| 9 | Chemical comparison of dried rehmannia root and prepared rehmannia root by UPLC-TOF MS and HPLC-ELSD with multivariate statistical analysis显示文摘To identify the chemical differences which lead to the different therapeutic effects of dried rehmannia root(DRR)and prepared rehmannia root(PRR),we compared the chemical composition of decoctions of randomly purchased DRR and PRR using ultra performance liquid chromatography(UPLC)coupled with time-of-fight mass spectrometry and high performance liquid chromatography(HPLC)coupled with evaporative light scattering detection(ELSD)with the aid of multivariate statistical analysis.Both approaches clearly revealed compositional and quantitative differences between DRR and PRR.UPLC-MS data indicated stachyose,rehmaiono-side A(or rehmaionoside B),acteoside(or forsythiaside,or isoacteoside),6-O-coumaroylajugol(or 6-O-E-feruloylajugol,or 6-O-Z-feruloylajugol)as important discriminators between DRR and PRR decoctions.HPLC-ELSD analysis showed that the content of fructose in the decoctions of PRR was about four times greater than that of DRR(P<10^(-5)),while sucrose content in the decoctions of PRR was only about one seventh of that in DRR(P<0.01).Our results suggest that some compounds,such as fructose,stachyose and rehmaionoside,may be responsible for the differing therapeutic effects of DRR and PRR.Furthermore,improvements in quality control for PRR,which is currently lacking in the Chinese Pharmacopoeia,are recommended. | Qiande Liang Jing Ma Zengchun Ma Yuguang Wang Hongling Tan Chengrong Xiao Ming Liu Beibei Lu Boli Zhang Yue Gao | 2013 | Acta Pharmaceutica Sinica B2013，3，1： | 8 |
| 10 | Dynamic-Change Laws of the Porosity and Permeability of Low-to Medium-Rank Coals under Heating and Pressurization Treatments in the Eastern Junggar Basin,China显示文摘Deep coalbed methane exists in high-temperature and high-pressure reservoirs. To elucidate the dynamic-change laws of the deep coal reservoir porosity and permeability characteristics in the process of coalbed methane production, based on three pieces of low-to medium-rank coal samples in the eastern Junggar Basin, Xinjiang, we analyse their mercury-injection pore structures. We measured the porosity and permeability of the coal samples at various temperatures and confining pressures by high-temperature and confining pressure testing. The results show that the porosity of a coal sample decreases exponentially with increasing effective stress. With increasing temperature, the initial porosity increases for two pieces of relatively low-rank coal samples. The increased rate of porosity decreases with increasing confining pressure. With increasing temperature, the initial porosity of a relatively high-rank coal sample decreases, and the rate of change of the porosity become faster. An exponential relationship exists between the porosity and permeability. With increasing coal rank, the initial porosity and permeability decrease. The change rate of the permeability decreases with increasing porosity. | Gang Wang Yong Qin Jian Shen Shuyuan Chen Beibei Han Xiaoting Zhou | 2018 | Journal of Earth Science2018，29，3： | 8 |
| 11 | Size control of monodisperse nonporous silica particles by seed particle growth显示文摘Monodisperse nonporous silica particles were prepared by sol-precipitation via seed particle growth method,and the particle size,which varied from 1.0 to 4.7 m,was strictly controlled in our experiment. The formation of secondary particles,which resulted in a multimodal distribution of particle size,was suppressed by changing tetraethoxysilane(TEOS) concentration and reaction temperature. Furthermore,the effect of adding small amounts of electrolyte to the hydrolysis mixture was examined. | Beibei Zhao Caihua Tian Yan Zhang Tao Tang Fengyun Wang | 2011 | Particuology2011，9，3： | 7 |
| 12 | Preparation of high-purity monodisperse silica microspheres by the sol-gel method coupled with polymerization-induced colloid aggregation显示文摘Ultra-pure mesoporous silica microspheres with good monodispersity were synthesized in two steps:nanometer-sized silica sol was produced by the sol-gel process,then micrometer-sized silica microspheres were synthesized by polymerization-induced colloid aggregation of the silica sol.The total metal content of the microspheres was extremely low,which eliminated the tailing of chromatographic peaks by chelating reagents.The pore structure of the silica microspheres could be controlled by altering the sol-gel conditions.The silica microsphere particle size could be adjusted by using different polymerizationinduced colloid aggregation conditions. | Beibei Zhao Yan Zhang Tao Tang Fengyun Wang Tong Li Qiyu Lu | 2015 | Particuology2015，13，5： | 7 |
| 13 | sLe^(x) expression in invasive micropapillary breast carcinoma is associated with poor prognosis and can be combined with MUC1/EMA as a supplementary diagnostic indicator显示文摘Objective: Mucin 1(MUC1/EMA) and sialyl Lewis X(sLe^(x)) indicate polarity reversal in invasive micropapillary carcinoma(IMPC). The purpose of this study was to evaluate the expression of MUC1/EMA and sLe^(x) and to assess their diagnostic and prognostic value in patients with IMPC.Methods: The expression of sLe^(x) and MUC1/EMA in 100 patients with IMPC and a control group of 89 patients with invasive ductal carcinoma not otherwise specified(IDC-NOS) were analyzed with IHC. Fresh tumor tissues were collected from patients with IMPC or IDC-NOS for primary culture and immunofluorescence analysis.Results: The rate of nodal metastasis was higher in patients with IMPC than those with IDC-NOS, and IMPC cells tended to express more sLe^(x) and MUC1/EMA in the cytomembranes(the stroma-facing surfaces of the micropapillary clusters) than IDC-NOS cells. In IMPC, high cytomembrane expression of sLe^(x), but not MUC1/EMA, indicated poor prognosis. In addition, among the 100 patients with IMPC, 10 patients had sLe^(x)+/EMA-expression patterns, and 8 patients had sLe^(x)-/EMA+ expression patterns. The primary IMPC cells were suspended, non-adherent tumor cell clusters, whereas the primary IDC cells were adherent tumor cells. Immunofluorescence analysis showed that MUC1/EMA and sLe^(x) were co-expressed on the cytomembranes in IMPC cell clusters and in the cytoplasm in IDC-NOS cells.Conclusions: sLe^(x) can be used as a prognostic indicator and can be combined with MUC1/EMA as a complementary diagnostic indicator to avoid missed IMPC diagnosis. | Yawen Song Hui Sun Kailiang Wu Jianke Lyu Jingyue Zhang Feng Gu Yongjie Ma Beibei Shen Chijuan Wang Xiaojiao Chen Jing Xu Weidong Li Fangfang Liu Li Fu | 2021 | Cancer Biology & Medicine2021，18，2： | 7 |
| 14 | Health risk assessment of dietary exposure to polycyclic aromatic hydrocarbons in Taiyuan, China显示文摘Sixteen polycyclic aromatic hydrocarbons(PAHs) were determined in 24 duplicate-diet samples from people in Taiyuan during summer and winter in 2009. Dietary intake of PAHs for 2862 participants was subsequently estimated by a survey in Taiyuan. Results from these 24 samples were compared with a raw food study in Taiyuan in 2008. Three main sources of dietary PAHs are vegetables, wheat flour and fruits, the sum of which contributes 75.95% of PAHs in dietary food. Compared to the estimated value in raw food, much more B[a]Peq(benzo[a]pyrene equivalents) were detected in food samples collected in the duplicate-diet study in Taiyuan(60.75 ng/day). The cooking process may introduce more B[a]Peq into food, and the relative contribution of 16 PAHs in the diet would be changed during the cooking procedure. | Jing Nie Jing Shi Xiaoli Duan Beibei Wang Nan Huang Xiuge Zhao | 2014 | Journal of Environmental Sciences2014，26，2： | 6 |
| 15 | FGF1^(△HBS) prevents diabetic cardiomyopathy by maintaining mitochondrial homeostasis and reducing oxidative stress via AMPK/Nur77 suppression显示文摘As a classically known mitogen,fibroblast growth factor 1(FGF1)has been found to exert other pleiotropic functions such as metabolic regulation and myocardial protection.Here,we show that serum levels of FGF1 were decreased and positively correlated with fraction shortening in diabetic cardiomyopathy(DCM)patients,indicating that FGF1 is a potential therapeutic target for DCM.We found that treatment with a FGF1 variant(FGF1^(△HBS))with reduced proliferative potency prevented diabetes-induced cardiac injury and remodeling and restored cardiac function.RNA-Seq results obtained from the cardiac tissues of db/db mice showed significant increase in the expression levels of anti-oxidative genes and decrease of Nur77 by FGF1AHBS treatment.Both in vivo and in vitro studies indicate that FGF1^(△HBS) exerted these beneficial effects by markedly reducing mitochondrial fragmentation,reactive oxygen species(ROS)generation and cytochrome c leakage and enhancing mitochondrial respiration rate and β-oxidation in a 5;AMP-activated protein kinase(AMPK)/Nur77-dependent manner,all of which were not observed in the AMPK null mice.The favorable metabolic activity and reduced proliferative properties of FGF1^(△HBS) testify to its promising potential for use in the treatment of DCM and other metabolic disorders. | Dezhong Wang Yuan Yin Shuyi Wang Tianyang Zhao Fanghua Gong Yushuo Zhao Beibei Wang Yuli Huang Zizhao Cheng Guanghui Zhu Zengshou Wang Yang Wang Jun Ren Guang Liang Xiaokun Li Zhifeng Huang | 2021 | Signal Transduction and Targeted Therapy2021，6，4： | 6 |
| 16 | Adjuvant treatment for triple-negative breast cancer: a retrospective study of immunotherapy with autologous cytokine-induced killer cells in 294 patients显示文摘Objective: To examine the efficacy and safety of a sequential combination of chemotherapy and autologous cytokine-induced killer(CIK) cell treatment in triple-negative breast cancer(TNBC) patients.Methods: A total of 294 post-surgery TNBC patients participated in the research from January 1, 2009 to January 1, 2015. After adjuvant chemotherapy, autologous CIK cells were introduced in 147 cases(CIK group), while adjuvant chemotherapy alone was used to treat the remaining 147 cases(control group). The major endpoints of the investigation were the disease-free survival(DFS) and overall survival(OS). Additionally, the side effects of the treatment were evaluated.Results: In the CIK group, the DFS and OS intervals of the patients were significantly longer than those of the control group(DFS:P = 0.047;OS: P = 0.007). The multivariate analysis demonstrated that the TNM(tumor-node-metastasis) stage and adjuvant CIK treatment were independent prognostic factors for both DFS [hazard ratio(HR)= 0.520, 95% confidence interval(CI):0.271-0.998, P = 0.049;HR = 1.449, 95% CI:1.118-1.877, P = 0.005, respectively] and OS(HR=0.414, 95% CI:0.190-0.903, P = 0.027;HR= 1.581, 95% CI:1.204-2.077, P = 0.001, respectively) in patients with TNBC. Additionally, longer DFS and OS intervals were associated with increased number of CIK treatment cycles(DFS: P = 0.020;OS: P = 0.040). The majority of the patients who benefitted from CIK cell therapy were relatively early-stage TNBC patients.Conclusion: Chemotherapy in combination with adjuvant CIK could be used to lower the relapse and metastasis rate, thus effectively extending the survival time of TNBC patients, especially those at early stages. | Yuhan Zhang Shuaibing Wang Beibei Yang Su Lu Yiyi Du Hong Liu | 2019 | Cancer Biology & Medicine2019，16，2： | 6 |

| 18 | WGDI:A user-friendly toolkit for evolutionary analyses of whole-genome duplications and ancestral karyotypes显示文摘Evidence of whole-genome duplications(WGDs)and subsequent karyotype changes has been detected in most major lineages of living organisms on Earth.To clarify the complex resulting multi-layered patterns of gene collinearity in genome analyses,there is a need for convenient and accurate toolkits.To meet this need,we developed WGDI(Whole-Genome Duplication Integrated analysis),a Python-based command-line tool that facilitates comprehensive analysis of recursive polyploidization events and cross-species genome alignments.WGDI supports three main workflows(polyploid inference,hierarchical inference of genomic homology,and ancestral chromosome karyotyping)that can improve the detection of WGD and characterization of WGD-related events based on high-quality chromosome-level genomes.Significantly,it can extract complete synteny blocks and facilitate reconstruction of detailed karyotype evolution.This toolkit is freely available at GitHub(http://gffzz188fe103f8f1460asxnfvv59bk9of6cqn.ffgz.tsg.suse.edu.cn/SunPengChuan/wgdi).As an example of its application,WGDI convincingly clarified karyotype evolution in Aquilegia coerulea and Vitis vinifera following WGDs and rejected the hypothesis that Aquilegia contributed as a parental lineage to the allopolyploid origin of core dicots. | Pengchuan Sun Beibei Jiao Yongzhi Yang Lanxing Shan Ting Li Xiaonan Li Zhenxiang Xi Xiyin Wang Jianquan Liu | 2022 | Molecular Plant2022，15，12： | 5 |
| 19 | Metabolic characteristics and nutrient utilization in high-feedefficiency pigs selected using different feed conversion ratio models显示文摘An understanding of the nutrient utilization characteristics of pigs with different feed efficiencies(FEs) will help us to develop new strategies to reduce the costs of pig production.In this study,we selected pigs with a range of FEs according to two feed conversion ratio models: the feed intake(FI) model,where pigs had the same average daily gains(ADGs) but different FIs,and the ADG model,where pigs had the same FIs but different ADGs.High-FE pigs had a higher abundance of short chain fatty acid(SCFA)-producing bacteria(Lachnospiraceae,Clostridiaceae1,and Coriobacteriaceae) in their caecum in the FI model,and low-FE pigs had a higher abundance of two families(BacteroidalesS247group and Peptococcaceae) and two genera(Anaerotruncus and CandidatusSoleaferrea) in both models.By contrast,high-FE pigs had more goblet cells and higher m RNA expression of insulin-like growth factor 1(IGF-1) in the FI model,and higher mRNA expression of occludin but lower expressions of adenosine monophosphate-activated protein kinase(AMPK)-α2 and peroxisome proliferator-activated receptor gamma coactivator 1 alpha(PGC1α) in the ADG model.These findings suggest that the presence of SCFA-producing bacteria in the caecum and increased muscular growth may contribute to the high FE of low-FI pigs,while improved intestinal functions and decreased mitochondrial activity in the skeletal muscle are related to the high FE of high-ADG pigs. | Beibei He Tiantian Li Wei Wang Hang Gao Yu Bai Shuai Zhang Jianjun Zang Defa Li Junjun Wang | 2019 | Science China(Life Sciences)2019，62，7： | 5 |
| 20 | Unraveling a genetic roadmap for improved taste in the domesticated apple显示文摘Although taste is an important aspect of fruit quality, an understanding of its genetic control remains elusive in apple and other fruit crops. In this study, we conducted genomic sequence analysis of 497 Malus accessions and revealed erosion of genetic diversity caused by apple breeding and possible independent domestication events of dessert and cider apples. Signatures of selection for fruit acidity and size, but not for fruit sugar content, were detected during the processes of both domestication and improvement. Furthermore, we found that single mutations in major genes affecting fruit taste, including Ma1, MdTDT, and MdSOT2, dramatically decrease malate, citrate, and sorbitol accumulation, respectively, and correspond to important domestication events. Interestingly, Ma1 was identified to have pleiotropic effects on both organic acid content and sugar:acid ratio, suggesting that it plays a vital role in determining fruit taste. Fruit taste is unlikely to have been negatively affected by linkage drag associated with selection for larger fruit that resulted from the pyramiding of multiple genes with minor effects on fruit size. Collectively, our study provides new insights into the genetic basis of fruit quality and its evolutionary roadmap during apple domestication, pinpointing several candidate genes for genetic manipulation of fruit taste in apple. | Liao Liao Weihan Zhang Bo Zhang Ting Fang Xiao-Fei Wang Yarning Cai Collins Ogutu Lei Gao Gang Chen Xiaoqing Nie Jinsheng Xu Quanyan Zhang Yiran Ren Jianqiang Yu Chukun Wang Cecilia H.Deng Baiquan Ma Beibei Zheng Chun-Xiang You Da-Gang Hu Richard Espley Kui Lin-Wang Jia-Long Yao Andrew C.Allan Awais Khan Schuyler S.Korban Zhangjun Fei Ray Ming Yu-Jin Hao Li Li Yuepeng Han | 2021 | Molecular Plant2021，14，9： | 5 |
