| 1 | Strong ozone production at a rural site in the North China Plain: Mixed effects of urban plumes and biogenic emissions显示文摘Regional ozone(O_3) pollution has drawn increasing attention in China over the recent decade, but the contributions from urban pollution and biogenic emissions have not been clearly elucidated. To better understand the formation of the regional O_3 problem in the North China Plain(NCP), intensive field measurements of O_3 and related parameters were conducted at a rural site downwind of Ji'nan, the capital city of Shandong province, in the summer of 2013. Markedly severe O_3 pollution was recorded, with the O_3 mixing ratios exceeding the Chinese national ambient air quality standard on 28 days(a frequency of 78%) and with a maximum hourly value of 198 ppbv. Extensive regional transport of wellprocessed urban plumes to the site was identified. An observation-constrained chemical box model was deployed to evaluate in situ photochemical O_3 production on two episodes.The results show that the in situ formation accounted for approximately 46% of the observed O_3 accumulation, while the remainder(~54%) was contributed by regional transport of the O_3-laden urban plumes. The in situ ozone production was in a mixed controlled regime that reducing either NOx or VOCs would lead to a reduction of ozone formation. Biogenic VOCs played an important role in the local ozone formation. This study demonstrates the significant mixed effects of both anthropogenic pollution from urban zones and biogenic emission in rural areas on the regional O_3 pollution in the NCP region,and may have general applicability in facilitating the understanding of the formation of secondary pollution over China. | Ruihan Zong Xue Yang Liang Wen Caihong Xu Yanhong Zhu Tianshu Chen Lan Yao Liwei Wang Junmei Zhang Lingxiao Yang Xinfeng Wang Min Shao Tong Zhu Likun Xue Wenxing Wang | 2018 | Journal of Environmental Sciences2018，30，9： | 8 |
| 2 | Copper-Bismuth Bimetallic Microspheres for Selective Electrocatalytic Reduction of CO2 to Formate显示文摘Summary of main observation and conclusion Electrocatalytic carbon dioxide reduction holds great promise for reducing the atmospheric CO2 level and alleviating the energy crisis. High-performance electrocatalysts are often required in order to lower the high overpotential and expedite the sluggish reaction kinetics of CO2 electroreduction. Copper is a promising candidate metal. However, it usually suffers from the issues of poor stability and low product selectivity. In this work, bimetallic Cu-Bi is obtained by reducing the microspherical copper bismuthate (CuBi2O4) for selectively catalyzing the CO2 reduction to formate (HCOO-). The bimetallic Cu-Bi electrocatalyst exhibits high activity and selectivity with the Faradic efficiency over 90% in a wide potential window. A maximum Faradaic efficiency of ~95% is obtained at -0.93 V versus reversible hydrogen electrode. Furthermore, the catalyst shows high stability over 6 h with Faradaic efficiency of -95%. This study provides an important clue in designing new functional materials for CO2 electroreduction with high activity and selectivity. | Lin Jia Hui Yang Jun Deng Junmei Chen Yuan Zhou Pan Ding Leigang Li Na Han Yanguang Li | 2019 | Chinese Journal of Chemistry2019，37，5： | 8 |

| 4 | Cobalt atoms dispersed on hierarchical carbon nitride support as the cathode electrocatalyst for high-performance lithium-polysulfide batteries显示文摘Lithium-sulfur batteries are promising candidates for next-generation energy storage but are confronted with several challenges. One of the possible solutions is to design proper cathode electrocatalysts to accelerate the redox interconversion of solvated polysulfide intermediates. Herein, we report cobalt atoms dispersed on hierarchical carbon nitride support as an effective cathode electrocatalyst for lithium-polysulfide batteries. The electrocatalyst material is prepared from the simple reaction between melamine and cyanuric acid in the presence of Co^2+, followed by the Ar annealing. The product has a unique hierarchical structure consisting of many thin and porous C3 N4 nanosheets finely dispersed with Co atoms. The atomic dispersion of Co species is confirmed by X-ray absorption experiments.Electrochemical measurements reveal that it can promote the interconversion of polysulfides. As a result,batteries using this cathode electrocatalyst achieve large capacity($1400 mAh/g at 1.6 mA/cm^2), good rate performance($800 mAh/g at 12.8 mA/cm^2) and impressive cycling stability under different current densities and different sulfur loadings. | Jialing Wu Junmei Chen Yang Huang Kun Feng Jun Deng Wei Huang Yunling Wu Jun Zhong Yanguang Li | 2019 | Science Bulletin2019，64，24： | 7 |

| 6 | A global alfalfa diversity panel reveals genomic selection signatures in Chinese varieties and genomic associations with root development显示文摘Alfalfa(Medicago sativa L.) is an important forage crop worldwide. However, little is known about the effects of breeding status and different geographical populations on alfalfa improvement. Here, we sequenced 220 alfalfa core germplasms and determined that Chinese alfalfa cultivars form an independent group, as evidenced by comparisons of FSTvalues between different subgroups, suggesting that geographical origin plays an important role in group differentiation. By tracing the influence of geographical regions on the genetic diversity of alfalfa varieties in China, we identified 350 common candidate genetic regions and 548 genes under selection. We also defined 165 loci associated with 24 important traits from genome-wide association studies. Of those, 17 genomic regions closely associated with a given phenotype were under selection, with the underlying haplotypes showing significant differences between subgroups of distinct geographical origins. Based on results from expression analysis and association mapping,we propose that 6-phosphogluconolactonase(MsPGL) and a gene encoding a protein with NHL domains(MsNHL) are critical candidate genes for root growth. In conclusion, our results provide valuable information for alfalfa improvement via molecular breeding. | Lin Chen Fei He Ruicai Long Fan Zhang Mingna Li Zhen Wang Junmei Kang Qingchuan Yang | 2021 | Journal of Integrative Plant Biology2021，63，11： | 3 |
| 7 | Research on Hybrid Model of Garlic Short-term Price Forecasting based on Big Data显示文摘Garlic prices fluctuate dramatically in recent years and it is very difficult to predict garlic prices.The autoregressive integrated moving average(ARIMA)model is currently the most important method for predicting garlic prices.However,the ARIMA model can only predict the linear part of the garlic prices,and cannot predict its nonlinear part.Therefore,it is urgent to adopt a method to analyze the nonlinear characteristics of garlic prices.After comparing the advantages and disadvantages of several major prediction models which used to forecast nonlinear time series,using support vector machine(SVM)model to predict the nonlinear part of garlic prices and establish ARIMA-SVM hybrid forecast model to predict garlic prices.The monthly average price data of garlic in 2010-2017 was used to test the effect of ARIMA model,SVM model and ARIMA-SVM model.The experimental results show that:(1)Garlic price is affected by many factors but the most is the supply and demand relationship;(2)The SVM model has a good effect in dealing with the nonlinear relationship of garlic prices;(3)The ARIMA-SVM hybrid model is better than the single ARIMA model and SVM model on the accuracy of garlic price prediction,it can be used as an effective method to predict the short-term price of garlic. | Baojia Wang Pingzeng Liu Zhang Chao Wang Junmei Weijie Chen Ning Cao Gregory MPO’Hare Fujiang Wen | 2018 | Computers, Materials & Continua2018，，11： | 3 |
| 8 | Antrodia cinnamomea exerts an anti-hepatoma effect by targeting PI3K/AKT-mediated cell cycle progression in vitro and in vivo显示文摘Antrodia cinnamomea is extensively used as a traditional medicine to prevention and treatment of liver cancer.However,its comprehensive chemical fingerprint is uncertain,and the mechanisms,especially the potential therapeutic target for anti-hepatocellular carcinoma(HCC)are still unclear.Using UPLC-Q-TOF/MS,139 chemical components were identified in A.cinnamomea dropping pills(ACDPs).Based on these chemical components,network pharmacology demonstrated that the targets of active components were significantly enriched in the pathways in cancer,which were closely related with cell proliferation regulation.Next,HCC data was downloaded from Gene Expression Omnibus database(GEO).The Cancer Genome Atlas(TCGA)and Dis Ge NET were analyzed by bioinformatics,and 79 biomarkers were obtained.Furtherly,nine targets of ACDP active components were revealed,and they were significantly enriched in PI3 K/AKT and cell cycle signaling pathways.The affinity between these targets and their corresponding active ingredients was predicted by molecular docking.Finally,in vivo and in vitro experiments showed that ACDPs could reduce the activity of PI3 K/AKT signaling pathway and downregulate the expression of cell cycle-related proteins,contributing to the decreased growth of liver cancer.Altogether,PI3 K/AKT-cell cycle appears as the significant central node in anti-liver cancer of A.Cinnamomea. | Yan Zhang Pin Lv Junmei Ma Ning Chen Huishan Guo Yan Chen Xiaoruo Gan Rong Wang Xuqiang Liu Sufang Fan Bin Cong Wenyi Kang | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 2 |
| 9 | Noggin versus basic fibroblast growth factor on the differentiation of human embryonic stem cells显示文摘The difference between Noggin and basic fibroblast growth factor for the neural precursor differen-tiation from human embryonic stem cells has not been studied. In this study, 100 μg/L Noggin or 20 μg/L basic fibroblast growth factor in serum-free neural induction medium was used to differen-tiate human embryonic stem cells H14 into neural precursors using monolayer differentiation. Two weeks after induction, significantly higher numbers of neural rosettes formed in the Noggin-induced group than the basic fibroblast growth factor-induced group, as detected by phase contrast micro-scope. Immunofluorescence staining revealed expression levels of Nestin, β-III Tubulin and Sox-1 were higher in the induced cells and reverse-transcription PCR showed induced cells expressed Nestin, Sox-1 and Neurofilament mRNA. Protein and mRNA expression in the Noggin-induced group was increased compared with the basic fibroblast growth factor-induced group. Noggin has a greater effect than basic fibroblast growth factor on the induction of human embryonic stem cell differentiation into neural precursors by monolayer differentiation, as Noggin accelerates and in-creases the differentiation of neural precursors. | Yan Zhang Junmei Zhou Zhenfu Fang Manxi Jiang Xuejin Chen | 2013 | Neural Regeneration Research2013，8，23： | 2 |
| 10 | Large Scale One-Pot Synthesis of Monodispersed Na_(3)(VOPO_(4))_(2)F Cathode for Na-Ion Batteries显示文摘Na-ion batteries(NIBs)have received significant interest as potential candidates for large-scale energy storage owing to the widespread distribution of sodium and superior low-temperature performance.However,their commercial application is usually hindered by the high production cost and inadequate performance for electrode materials,particularly for cathodes.Na_(3)(VOPO_(4))_(2)F(NVOPF)has been recognized as one of the most promising cathodes for high-energy NIBs owing to the high working voltage and energy density.Here,we report a facile highly efficient room-temperature solution protocol for large-scale synthesis of NVOPF cathode for NIBs.By simply regulating pH,NVOPF can be obtained,which delivered a discharge capacity of 120.2 mAh g^(-1) at 0.1 C and 72%capacity retention over 8000 cycles at 25 C.Besides,the kilogram-level NVOPF products have been synthesized,and 26650 cylindrical cells were fabricated,which exhibit excellent cycling stabilities,remarkable lowtemperature performance with comparable safety features.We hope our findings could provide insights on the industrial application of NVOPF in NIBs. | Qiangqiang Zhang Xing Shen Quan Zhou Kaixuan Li Feixiang Ding Yaxiang Lu Junmei Zhao Liquan Chen Yong-Sheng Hu | 2022 | Energy Material Advances2022，，1： | 2 |
| 11 | Isolation of prostrate turfgrass mutants via screening of dwarf phenotype and characterization of a perennial ryegrass prostrate mutant显示文摘Prostrate turf varieties are desirable because of their increased low mowing tolerance,heat resistance,traffic resistance and ground coverage compared with upright varieties.Mutation breeding may provide a powerful tool to create prostrate varieties,but there are no simple,straightforward methods to screen for such mutants.Elucidation of the molecular basis of the major‘green revolution’traits,dwarfism and semi-dwarfism,guided us to design a simple strategy for isolating dwarf mutants of perennial ryegrass(Lolium perenne L.).We have shown that gamma-ray-mediated dominant dwarf mutants can be easily screened for at the three-leaf stage.About 10%of dwarf mutant lines also displayed a prostrate phenotype at mature stages(>10 tillers).One prostrate line,Lowboy I,has been characterized in detail.Lowboy I had significantly shorter canopy,leaf blade and internode lengths compared with wild type.Lowboy I also exhibited greater tolerance to low mowing stress than wild type.Exogenous gibberellic acid(GA)restored Lowboy I to a wild-type phenotype,indicating that the dwarf and prostrate phenotypes were both due to GA deficiency.We further showed that phenotypes of Lowboy I were dominant and stably inherited through sexual reproduction.Prostrate turfgrass mutants are difficult to screen for because the phenotype is not observed at young seedling stages,therefore our method represents a simple strategy for easily isolating prostrate mutants.Furthermore,Lowboy I may provide an outstanding germplasm for breeding novel prostrate perennial ryegrass cultivars. | Junmei Chen Chandra Thammina Wei Li Hao Yu Huseyin Yer Rania El-Tanbouly Manon Marron Lorenzo Katin-Grazzini Yongqin Chen John Inguagiato Richard J.McAvoy Karl Guillard Xian Zhang Yi Li | 2016 | Horticulture Research2016，3，1： | 1 |

| 17 | Genome Assembly of Alfalfa Cultivar Zhongmu-4 and Identification of SNPs Associated with Agronomic Traits显示文摘Alfalfa(Medicago sativa L.)is the most important legume forage crop worldwide with high nutritional value and yield.For a long time,the breeding of alfalfa was hampered by lacking reliable information on the autotetraploid genome and molecular markers linked to important agronomic traits.We herein reported the de novo assembly of the allele-aware chromosome-level genome of Zhongmu-4,a cultivar widely cultivated in China,and a comprehensive database of genomic variations based on resequencing of 220 germplasms.Approximate 2.74 Gb contigs(N50 of 2.06 Mb),accounting for 88.39%of the estimated genome,were assembled,and 2.56 Gb contigs were anchored to 32 pseudo-chromosomes.A total of 34,922 allelic genes were identified from the allele-aware genome.We observed the expansion of gene families,especially those related to the nitrogen metabolism,and the increase of repetitive elements including transposable elements,which probably resulted in the increase of Zhongmu-4 genome compared with Medicago truncatula.Population structure analysis revealed that the accessions from Asia and South America had relatively lower genetic diversity than those from Europe,suggesting that geography may influence alfalfa genetic divergence during local adaption.Genome-wide association studies identified 101 single nucleotide polymorphisms(SNPs)associated with 27 agronomic traits.Two candidate genes were predicted to be correlated with fall dormancy and salt response.We believe that the alleleaware chromosome-level genome sequence of Zhongmu-4 combined with the resequencing data of the diverse alfalfa germplasms will facilitate genetic research and genomics-assisted breeding in variety improvement of alfalfa. | Ruicai Long Fan Zhang Zhiwu Zhang Mingna Li Lin Chen Xue Wang Wenwen Liu Tiejun Zhang Long-Xi Yu Fei He Xueqian Jiang Xijiang Yang Changfu Yang Zhen Wang Junmei Kang Qingchuan Yang | 2022 | Genomics, Proteomics & Bioinformatics2022，20，1： | 1 |
