| 3 | Effective genome editing and identification of a regiospecific gallic acid 4-O-glycosyltransferase in pomegranate(Punica granatum L.)显示文摘Pomegranate(Punica granatum L.)trees are woody perennials that bear colorful and nutritious fruits rich in phenolic metabolites,e.g.,hydrolyzable tannins(HTs)and flavonoids.We here report genome editing and gene discovery in pomegranate hairy roots using Clustered Regularly Interspaced Short Palindromic Repeats(CRISPR)/CRISPR-associated protein 9(Cas9)(CRISPR/Cas9),coupled with transcriptome and biochemical analyses.Single guide RNAs(sgRNAs)were designed to target two UDP-dependent glycosyltransferases(UGTs),PgUGT84A23 and PgUGT84A24,which possess overlapping activities inβ-glucogallin(a galloylglucose ester;biosynthetic precursor of HTs)biosynthesis.A unique accumulation of gallic acid 3-O-and 4-O-glucosides(galloylglucose ethers)was observed in the PgUGT84A23 and PgUGT84A24 dual CRISPR/Cas9-edited lines(i.e.,ugt84a23 ugt84a24)but not the control(empty vector)or PgUGT84A23/PgUGT84A24 single edited lines(ugt84a23 or ugt84a24).Transcriptome and real-time qPCR analyses identified 11 UGTs with increased expression in the ugt84a23 ugt84a24 hairy roots compared to the controls.Of the 11 candidate UGTs,only PgUGT72BD1 used gallic acid as substrate and produced a regiospecific product gallic acid 4-O-glucoside.This work demonstrates that the CRISPR/Cas9 method can facilitate functional genomics studies in pomegranate and shows promise for capitalizing on the metabolic potential of pomegranate for germplasm improvement. | Lijing Chang Sheng Wu Li Tian | 2019 | Horticulture Research2019，6，1： | 8 |
| 4 | Regenerative Braking Strategy for Motor Hoist by Ultracapacitor显示文摘Rising concern in environmental issues on global scale has made energy saving in powered equipment a very important subject.In order to improve the energy efficiency and driving range of a motor hoist,a regenerative braking system is designed and discussed.The system takes a unique ultracapacitor-only approach to energy storage system.The bi-directional bride DC?DC converter which regulates current flow to and from the ultracapacitor operates in two modes:boost and buck,depending on the direction of the flow.In order to provide constant input and output current at the ultracapacitor,this system uses a double proportional-integral(PI) control strategy in regulating the duty cycle of PWM to the DC?DC converter.The permanent magnet synchronous motor(PWSM) drive system is also studied.The space vector pulse width modulation(SVPWM) technique,along with a two-closed-loop vector control model,is adopted after detailed analysis of PMSM characteristics.The overall model and control strategy for this regenerative braking system is ultimately built and simulated under the MATLAB and Simulink environment.A test platform is built to obtain experimental results.Analysis of the results reveals that more than half of the gravitational potential energy can be recovered by this system.Simulation and experimentation results testify the validity of the double PI control strategy for interface circuit of ultracapacitor and SVPWM strategy for PMSM. | BIAN Yongming ZHU Lijing LAN Hao LI Anhu XU Xinming | 2012 | Chinese Journal of Mechanical Engineering2012，25，2： | 7 |

| 7 | Porous NiCo_2O_4 nanowires supported on carbon cloth for flexible asymmetric supercapacitor with high energy density显示文摘Recently, binary metal oxides have been considerably researched for energy storage since it can provide higher electrical conductivity and electrochemical activity than single components. Besides, rational arrays structure design can effectively enhance the utilization of active material. In this article, we synthesis a porous NiCo_2O_4 nanowires arrays, which were intimate contact with flexible carbon cloth(CC)by a facile hydrothermal reaction and calcination treatment. The rational array structures of NiCo_2O_4 facilitate the diffusion of electrolyte and effectively increase the utilization of active material. The asobtained NiCo_2O_4@CC electrode exhibits a high capacitance of 1183 mF cm^(-2) and an outstanding capacitance retention of 90.4% after 3000 cycles. Furthermore, a flexible asymmetric supercapacitor(ASC)using NiCo_2O_4@CC as positive electrode and activated carbon cloth(ACC) as negative electrode was fabricated, which delivers a large capacitance of 750 mF cm^(-2)(12.5 F cm^(-3)), a high energy density of 0.24 mWh cm^(-2)(3.91 mWh cm^(-3)), as well as excellent cycle stability under different bending states.These remarkable results suggest that as-assembled NiCo_2O_4@CC//ACC ASC is a promising candidate in flexible energy storage applications. | Huifang Zhang Dengji Xiao Qian Li Yuanyuan Ma Shuxia Yuan Lijing Xie Chengmeng Chen Chunxiang Lu | 2018 | Journal of Energy Chemistry2018，27，1： | 6 |
| 8 | Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait. | Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling | 2022 | Molecular Plant2022，15，9： | 6 |

The 3DGF exhibited high specific surface area of 402.5 m2/g, controllable pores and mechanical flexibility, which was employed as the binder-free supercapacitor electrode and shows high specific gravimetric capacitance of 95 F/g at 0.5 A/g, with enhanced rate capability in 3 electrode KOH system. | Yidan Gao Yaoyao Zhang Yong Zhang Lijing Xie Xiaoming Li Fangyuan Su Xianxian Wei Zhiwei Xu Chengmeng Chen Rong Cai | 2016 | Journal of Energy Chemistry2016，25，1： | 5 |
| 10 | Insight into vitronectin structural evolution on material surface chemistries: The mediation for cell adhesion显示文摘Biomaterial surface chemistry engenders profound consequences on cell adhesion and the ultimate tissue response by adsorbing proteins from extracellular matrix,where vitronectin(Vn)is involved as one of the crucial mediator proteins.Deciphering the adsorption behaviors of Vn in molecular scale provides a useful account of how to design biomaterial surfaces.But the details of structural dynamics and consequential biological effect remain elusive.Herein,both experimental and computational approaches were applied to delineate the conformational and orientational evolution of Vn during adsorption onto self-assembled monolayers(SAMs)terminating with-COOH,-NH2,-CH3 and-OH.To unravel the interplay between cell binding and the charge and wettability of material surface,somatomedin-B(SMB)domain of Vn holding the RGD cell-binding motif was employed in molecular dynamics(MD)simulations,with orientation initialized by Monte Carlo(MC)method.Experimental evidences including protein adsorption,cell adhesion and integrin gene expressions were thoroughly investigated.The adsorption of Vn on different surface chemistries showed very complex profiles.Cell adhesion was enabled on all Vn-adsorbed surfaces but with distinct mechanisms mostly determined by conformational change induced reorientation.Higher amount of Vn was observed on negatively charged surface(COOH)and hydrophobic surface(CH3).However,advantageous orientations defined by RGD loop conditions were only obtained on the charged surfaces(COOH and NH2).Specifically,COOH surface straightened up the Vn molecules and accumulated them into a higher density,whereas CH3 surface squashed Vn and stacked them into higher density multilayer by tracking adsorption but with the RGD loops restrained.These findings may have a broad implication on the understanding of Vn functionality and would help develop new strategies for designing advanced biomaterials. | Tianjie Li Lijing Hao Jiangyu Li Chang Du Yingjun Wang | 2020 | Bioactive Materials2020，5，4： | 4 |
| 11 | Cellulose nanofiber separator for suppressing shuttle effect and Li dendrite formation in lithium-sulfur batteries显示文摘Lithium-sulfur battery(LSB) has high energy density but is limited by the polysulfides shuttle and dendrite growth during cycling. Herein, a free-standing cellulose nanofiber(CNF) separator is designed and fabricated in isopropanol/water suspension through vacuum filtration progress. CNFs with abundant polar oxygen-containing functional groups can chemically immobilize the polysulfides, and suppress the formation of the dendrites by controlling the surface morphology of the SEI on lithium metal in LSB. The isopropanol content in a suspension can fine-tune the pore structure of the membrane to achieve optimal electrochemical performance. The prepared separator displays integrated advantages of an ultrathin thickness(19 μm), lightweight(0.87 mg cm^(-2)), extremely high porosity(98.05%), and decent electrolyte affinity. As a result, the discharge capacity of the LSB with CNF separator at the first and 100 th cycle is 1.4 and 1.3 times that of PP separator, respectively. Our research provides an environmentalfriendly and facile strategy for the preparation of multifunctional separators for LSBs. | Jingxue Li Liqin Dai Zhefan Wang Hao Wang Lijing Xie Jingpeng Chen Chong Yan Hong Yuan Hongliang Wang Chengmeng Chen | 2022 | Journal of Energy Chemistry2022，31，4： | 4 |

| 13 | Unfolded protein response activation compensates endoplasmic reticulum-associated degradation deficiency in Arabidopsis显示文摘Abiotic stresses often disrupt protein folding and induce endoplasmic reticulum(ER) stress. There is a sophisticated ER quality control(ERQC) system to mitigate the effects of malfunctioning proteins and maintain ER homeostasis. The accumulation of misfolded proteins in the ER activates the unfolded protein response(UPR) to enhance ER protein folding and the degradation of misfolded proteins mediate by ERassociated degradation(ERAD). That ERQC reduces abiotic stress damage has been well studied in mammals and yeast. However, in plants, both ERAD and UPR have been studied separately and found to be critical for plant abiotic stress tolerance. In this study, we discovered thatUPR-associated transcription factors Atb ZIP17, AtbZIP28 and AtbZIP60 responded to tunicamycin(TM) and Na Cl induced ER stress and subsequently enhanced Arabidopsis thaliana abiotic stress tolerance. They regulated the expression level of ER chaperones and the HRD1-complex components. Moreover, overexpression of Atb ZIP17,Atb ZIP28 and Atb ZIP60 could restore stress tolerance via ERAD in the HRD1-complex mutant hrd3a-2, which suggested that UPR and ERAD have an interactive mechanism in Arabidopsis. | Qingliang Li Hai Wei Lijing Liu Xiaoyuan Yang Xiansheng Zhang Qi Xie | 2017 | Journal of Integrative Plant Biology2017，59，7： | 3 |
| 14 | Mechanistic insights into the adsorption and bioactivity of fibronectin on surfaces with varying chemistries by a combination of experimental strategies and molecular simulations显示文摘Fibronectin(Fn)is significant to the performance of biomaterials,and the chemistry of biomaterial surface play important roles in Fn adsorption and subsequent cell behavior.However,the“molecular scale”mechanism is still unclear.Herein,we combined experimental strategies with molecular simulations to solve this problem.We prepared self-assembled monolayers with varying chemistries,i.e.,SAMs-CH3,SAMs-NH2,SAMs-COOH and SAMs-OH,and characterized Fn adsorption and cell behaviors on them.Next,Monte Carlo method and all-atom molecular dynamics simulations were employed to reveal the orientation/conformation of Fn on surfaces.We found that SAMs-CH3 strongly adsorbed Fn via hydrophobic interactions,but show poor bioactivity as the low exposure of RGD/PHSRN motifs and the deformation of Fn.SAMs-NH2 and SAMs-COOH could adsorb Fn efficiently via vdW interactions,electrostatic interactions,hydrogen bonds and salt bridges.Fn exhibited excellent bioactivity for cell adhesion,proliferation and osteogenic differentiation as high exposure of bioactive motifs on SAMs-NH2,or as the activation of other inferior cell-binding motifs on SAMs-COOH.SAMs-OH showed poor Fn adsorption as the water film.However,the adsorbed Fn displayed non-negligible bioactivity due to high exposure of PHSRN motif and large degree of protein flexibility.We believe that the revealed mechanism presents great potential to rationally design Fn-activating biomaterials. | Lijing Hao Tianjie Li Lin Wang Xuetao Shi Yan Fan Chang Du Yingjun Wang | 2021 | Bioactive Materials2021，6，10： | 3 |
| 15 | Protein Function Prediction Based on Active Semi-supervised Learning显示文摘In our study,the active learning and semisupervised learning methods are comprehensively used for label delivery of proteins with known functions in Proteinprotein interaction(PPI) network so as to predict the functions of unknown proteins.Because the real PPI network is generally observed with overlapping protein nodes with multiple functions,the mislabeling of overlapping protein may result in accumulation of prediction errors.For this reason,prior to executing the label delivery process of semi-supervised learning,the adjacency matrix is used to detect overlapping proteins.As the topological structure description of interactive relation between proteins,PPI network is observed with party hub protein nodes that play an important role,in co-expression with its neighborhood.Therefore,to reduce the manual labeling cost,party hub proteins most beneficial for improvement of prediction accuracy are selected for class labeling and the labeled party hub proteins are added into the labeled sample set for semisupervised learning later.As the experimental results of real yeast PPI network show,the proposed algorithm can achieve high prediction accuracy with few labeled samples. | WANG Xuesong CHENG Yuhu LI Lijing | 2016 | Chinese Journal of Electronics2016，25，4： | 2 |
| 16 | Development of a Percentile Based Three-dimensional Model of the Buttocks in Computer System显示文摘There are diverse products related to human buttocks, which need to be designed, manufactured and evaluated with 3D buttock model. The 3D buttock model used in present research field is just simple approximate model similar to human buttocks. The 3D buttock percentile model is highly desired in the ergonomics design and evaluation for these products. So far, there is no research on the percentile sizing system of human 3D buttock model. So the purpose of this paper is to develop a new method for building three-dimensional buttock percentile model in computer system. After scanning the 3D shape of buttocks, the cloud data of 3D points is imported into the reverse engineering software(Geomagic) for the reconstructing of the buttock surface model. Five characteristic dimensions of the buttock are measured through mark-points after models being imported into engineering software CATIA. A series of space points are obtained by the intersecting of the cutting slices and 3D buttock surface model, and then are ordered based on the sequence number of the horizontal and vertical slices. The 1st, 5th, 50 th, 95 th, 99 th percentile values of the five dimensions and the spatial coordinate values of the space points are obtained, and used to reconstruct percentile buttock models. This research proposes a establishing method of percentile sizing system of buttock 3D model based on the percentile values of the ischial tuberosities diameter, the distances from margin to ischial tuberosity and the space coordinates value of coordinate points, for establishing the Nth percentile 3D buttock model and every special buttock types model. The proposed method also serves as a useful guidance for the other 3D percentile models establishment for other part in human body with characteristic points. | WANG Lijing HE Xueli LI Hongpeng | 2016 | Chinese Journal of Mechanical Engineering2016，29，3： | 2 |

| 18 | UBC32 Mediated Oxidative Tolerance in Arabidopsis显示文摘Extreme environments such as salt stress often increase the reactive oxygen species(ROS) levels(Abogadallah,2010; Miller et al.,2010),which cause protein denaturation and damage(Kelsen et al.,2008).In eukaryotic cells,the endoplasmic reticulum(ER) lumen is highly oxidative environment, which help newly synthesized proteins form intermolecular or intramolecular disulfide bonds between their cysteine residues. However,the ROS must be regulated according to the folding load to protect the cell from the consequences of oxidative folding.One way to control ROS level is to increase the expression level of ROS scavenger(Molteni et al.,2004); another way is to activate unfolded protein response(UPR), | Feng Cui Lijing Liu Qingliang Li Chengwei Yang Qi Xie | 2012 | Journal of Genetics and Genomics2012，39，8： | 2 |

| 20 | Characterization of Bioaerosol Bacterial Communities During Hazy and Foggy Weather in Qingdao, China显示文摘This study was conducted to evaluate the impact of hazy and foggy weather on the bacterial communities in bioaerosols, for which samples were collected from the Qingdao coastal region on sunny, foggy, and hazy days in January and March 2013. Bacterial community compositions were determined using polymerase chain reaction denaturing gradient gel electrophoresis(PCR-DGGE). The bacterial community diversity was found to be high on foggy and hazy days, and the dominant species differed during hazy weather. The Shannon-Wiener index revealed that the bacterial community diversity of coarse particles was higher than that of fine particles in the bioaerosols. The bacterial community diversity of fine particles significantly correlated with relative humidity(RH; r^2 = 0.986). The cluster analysis results indicated that the bacterial communities on sunny days differed from those on hazy and foggy days. Compared with sunny days, the bacterial communities in the fine particles during hazy weather exhibited greater changes than those in the coarse particles. Most of the sequenced bacteria were found to be closely affiliated with uncultured bacteria. During hazy weather, members of the classes Bacilli and Gammaproteobacteria(Pseudomonas and Acinetobacter) were dominant. The DGGE analysis revealed that Proteobacteria and Firmicutes were the predominant phyla, and their relative percentages to all the measured species changed significantly on hazy days, particularly in the fine particles. Haze and fog had a significant impact on the bacterial communities in bioaerosols, and the bacterial community diversity varied on different hazy days. | QI Jianhua LI Mengzhe ZHEN Yu WU Lijing | 2018 | Journal of Ocean University of China2018，17，3： | 2 |
