| 2 | A telomere-to-telomere gap-free reference genome of watermelon and its mutation library provide important resources for gene discovery and breeding显示文摘Watermelon,Citrullus lanatus,is the world's third largest fruit crop.Reference genomes with gaps and a narrow genetic base hinder functional genomics and genetic improvement of watermelon.Here,we report the assembly of a telomere-to-telomere gap-free genome of the elite watermelon inbred line G42 by incorporating high-coverage and accurate long-read sequencing data with multiple assembly strategies.All 11 chromosomes have been assembled into single-contig pseudomolecules without gaps,representing the highest completeness and assembly quality to date.The G42 reference genome is 369321829 bp in length and contains 24205 predicted protein-coding genes,with all 22 telomeres and 11 centromeres characterized.Furthermore,we established a pollen-EMS mutagenesis protocol and obtained over 200000M1 seeds from G42.In a sampling pool,48 monogenic phenotypic mutations,selected from 223M1and 78 M2 mutants with morphological changes,were confirmed.The average mutation density was 1 SNP/1.69Mband1 indel/4.55 Mb per M1 plant and 1SNP/1.08Mb and 1 indel/6.25 Mb per M2 plant.Taking advantage of the gap-free G42 genome,8039 mutations from 32 plants sampled from M1 and M2 families were identified with 100%accuracy,whereas only 25% of the randomly selected mutations identified using the 97103v2 reference genome could be confirmed.Using this library and the gap-free genome,two genes responsible for elongated fruit shape and male sterility(CiMs1)were identified,both caused by a single basechange from G to A.The validated gap-free genome and its EMS mutation library provide invaluable resources for functional genomics and genetic improvement of watermelon. | Yun Deng Shoucheng Liu Yilin Zhang Jingsheng Tan Xiaopeng Li Xiao Chu Binghua Xu Yao Tian Yudong Sun Bosheng Li YunbiXu Xing Wang Deng Hang He Xingping Zhang | 2022 | Molecular Plant2022,15,8: | 9 |
| 3 | Compound Danshen tablets downregulate amyloid protein precursor mRNA expression in a transgenic cell model of Alzheimer's disease Effects and a comparison with donepezil显示文摘After gene mutation, the pcDNA3.1/APP595/596 plasmid was transfected into HEK293 cells to establish a cell model of Alzheimer's disease. The cell model was treated with donepezil or compound Danshen tablets after culture for 72 hours. Reverse transcription-PCR showed that the mRNA expression of amyloid protein precursor decreased in all groups following culture for 24 hours, and that there was no significant difference in the amount of decrease between donepezil and compound Danshen tablets. Our results suggest that compound Danshen tablets can reduce expression of the mRNA for amyloid protein precursor in a transgenic cell model of Alzheimer's disease, with similar effects to donepezil. | Ren'an Qin Desheng Zhou Jiajun Wang Hua Hu Yang Yang Xiaoxuan Yao Xiaopeng Sun | 2012 | Neural Regeneration Research2012,7,9: | 8 |
| 4 | Enhanced Vitamin C Production Mediated by an ABA-Induced PTP-like Nucleotidase Improves Plant Drought Tolerance in Arabidopsis and Maize显示文摘Abscisic acid(ABA)is a key phytohormone that mediates environmental stress responses.Vitamin C,or L-ascorbic acid(AsA),is the most abundant antioxidant protecting against stress damage in plants.How the ABA and AsA signaling pathways interact in stress responses remains elusive.In this study,we characterized the role of a previously unidentified gene,PTPN(PTP-like Nucleotidase)in plant drought tolerance.In Arabidopsis,(AtPTPN was expressed in multiple tissues and upregulated by ABA and drought treatments.Loss-of-function mutants oiAtPTPN were hyposensitive to ABA but hypersensitive to drought stresses,whereas plants with enhanced expression AtPTPN showed opposite phenotypes to.Overexpression of maize PTPN(ZmPTPN)promoted,while knockdown oiZmPTPN inhibited plant drought tolerance,indicating conserved and positive roles of PTPN in plant drought tolerance.We found that both AtPTPN and ZmPTPN release Pi by hydrolyzing GDP/GMP/dGMP/IMP/dIMP,and that AtPTPN positively regulated AsA production via endogenous Pi content control.Consistently,overexpression of VTC2,the rate-limiting synthetic enzyme in AsA biosynthesis,promoted AsA production and plant drought tolerance,and these effects were largely dependent on AtPTPN activity.Furthermore,we demonstrated that the heat shock transcription factor HSFA6a directly binds the AtPTPN promoter and activates AtPTPN expression.Genetic analyses showed that AtPTPN is required for HSFA6a to regulate ABA and drought responses.Taken together,our data indicate that PTPN-mediated crosstalk between the ABA signaling and AsA biosynthesis pathways positively controls plant drought tolerance. | Hui Zhang Yanli Xiang Neng He Xiangguo Liu Hongbo Liu Liping Fang Fei Zhang Xiaopeng Sun Delin Zhang Xingwang Li William Terzaghi Jianbing Yan Mingqiu Dai | 2020 | Molecular Plant2020,13,5: | 7 |

| 7 | Mesoscale Dynamics and Its Application in Torrential Rainfall Systems in China显示文摘Progress over the past decade in understanding moisture-driven dynamics and torrential rain storms in China is reviewed in this paper. First, advances in incorporating moisture effects more realistically into theory are described, including the development of a new parameter, generalized moist potential vorticity(GMPV) and an improved moist ageostrophic Q vector(Qum). Advances in vorticity dynamics are also described, including the adoption of a 'parcel dynamic' approach to investigate the development of the vertical vorticity of an air parcel; a novel theory of slantwise vorticity development, proposed because vorticity develops easily near steep isentropic surfaces; and the development of the convective vorticity vector(CVV)as an effective new tool. The significant progress in both frontal dynamics and wave dynamics is also summarized, including the geostrophic adjustment of initial unbalanced flow and the dual role of boundary layer friction in frontogenesis, as well as the interaction between topography and fronts, which indicate that topographic perturbations alter both frontogenesis and frontal structure. For atmospheric vortices, mixed wave/vortex dynamics has been extended to explain the propagation of spiral rainbands and the development of dynamical instability in tropical cyclones. Finally, we review wave and basic flow interaction in torrential rainfall, for which it was necessary to extend existing theory from large-scale flows to mesoscale fields, enriching our knowledge of mesoscale atmospheric dynamics. | GAO Shouting TAN Zhemin ZHAO Sixiong LUO Zhexian LU Hancheng WANG Donghai CUI Chunguang CUI Xiaopeng SUN Jianhua | 2015 | Advances in Atmospheric Sciences2015,32,2: | 4 |
| 8 | Robust H_∞ Load Frequency Control of Multi-area Power System With Time Delay:A Sliding Mode Control Approach显示文摘This paper is devoted to investigate the robust H∞sliding mode load frequency control(SMLFC) of multi-area power system with time delay. By taking into account stochastic disturbances induced by the integration of renewable energies,a new sliding surface function is constructed to guarantee the fast response and robust performance, then the sliding mode control law is designed to guarantee the reach ability of the sliding surface in a finite-time interval. The sufficient robust frequency stabilization result for multi-area power system with time delay is presented in terms of linear matrix inequalities(LMIs). Finally,a two-area power system is provided to illustrate the usefulness and effectiveness of the obtained results. | Yonghui Sun Yingxuan Wang Zhinong Wei Guoqiang Sun Xiaopeng Wu | 2018 | IEEE/CAA Journal of Automatica Sinica2018,5,2: | 4 |
| 9 | TRIM35 mediates protection against influenza infection by activating TRAF3 and degrading viral PB2显示文摘Tripartite motif(TRIM)family proteins are important effectors of innate immunity against viral infections.Here we identified TRIM35 as a regulator of TRAF3 activation.Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon(IFN)in response to viral infection.777m35-deficient mice were more susceptible to influenza A virus(IAV)infection than were wild-type mice.TRIM35 promoted the RIG-Imediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1.IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3.TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2,thereby antagonizing its suppression of TRAF3 activation.Our in vitro and in vivo findings thus reveal novel roles of TRIM35,through catalyzing Lys63-or Lys48-linked polyubiquitination,in RIG-I antiviral immunity and mechanism of defense against IAV infection. | Nan Sun Li Jiang Miaomiao Ye Yihan Wang Guangwen Wang Xiaopeng Wan Yuhui Zhao Xia Wen Libin Liang Shujie Ma Liling Liu Zhigao Bu Hualan Chen Chengjun Li | 2020 | Protein & Cell2020,11,12: | 4 |
| 10 | An animal model of cerebral palsy induced by prenatal exposure to lipopolysaccharide and hypoxia显示文摘BACKGROUND:Neonatal cerebral palsy is mainly caused by prenatal factors.At present, an animal model of prenatal infection and early postnatal hypoxia does not exist.OBJECTIVE:To observe morphology and motor performance following prenatal infection and hypoxic insult-induced brain damage of neonatal rats to verify the feasibility to establish a model of cerebral palsy.DESIGN, TIME AND SETTING:A randomized, controlled, animal experiment was performed at the Laboratories of Xinjiang Center for Disease Control and Prevention from September 2007 to June 2008.MATERIALS:The hypoxic incubator was purchased from Shanghai Pediatric Medical Institute, China.Lipopolysaccharide (LPS, Escherichia coli, O55:B5) was purchased from Sigma-Aldrich (St.Louis, MO, USA).METHODS:A total of 27 Wistar rats, aged 7 days, were randomly assigned to sham-surgery group (n=15) with no carotid artery incision or hypoxia treatment, hypoxia/ischemia (H/I) group (n=12) undergoing ligature of the right common carotid artery followed by exposure to hypoxia at postnatal day 7 (P7), and LPS/H group (n=19), in which pregnant rats were exposed in utero to LPS followed by prenatal hypoxia at embryonic day 16.MAIN OUTCOME MEASURES:Behavior, compound muscle action potential, and pathological changes were observed in 28-day-old rats.RESULTS:The footprint repeat space showed that left limb footprint repeatability in the H/I and LPS/H groups was lower than in the sham-surgery group (P<0.05).The space between the footprints was larger and unstable.Hind limb quadricep compound muscle action potential in the H/I and LPS/H groups showed lower wave amplitude compared with the sham-surgery group (P<0.05).Hematoxylin and eosin staining showed irregular cells around the ventricle, as well as periventricular leukomalacia.CONCLUSION:An animal model of cerebral palsy was established, which simulated the human condition most likely associated with occurrence of this disease.This model could be used for experimental studies related to cerebral palsy. | Gang Chen Yanrong HU Wei Liu Jiang Li Linbao Wen Jianxin Li Lihui Zhao Xiaopeng Yang Yi Zhu Zhenzhu Sun Guangming Chi | 2010 | Neural Regeneration Research2010,5,14: | 4 |
| 11 | Insight into selective removal of copper from high-concentration nickel solutions with XPS and DFT:New technique to prepare 5N-nickel with chelating resin显示文摘An efficient and profitable separation process was proposed to prepare 5N(the purity of the metal solution reaches 99.999%) high-purity nickel from 3N nickel-solutions using Purolite S984. The adsorption performance of this superior resin, especially its selectivity for metal ions,was explored quantitatively. The maximum adsorption capacity for copper was 2.286 mmol/g calculated by the Langmuir model, which was twice as large as that for nickel. In the binary systems, the adsorption capacity for nickel was decreased by 45%, indicating direct competition for the active sites. The infinite separation factor for copper versus nickel exceeded 300, revealing the feasibility of preparing5N-level high-purity nickel solutions, which was further verified using the 800 BV(bed volume) effluent in the column dynamic process.According to the cost–benefit analysis, purification contributed to a profit of approximately 60,000 USD per cycle, and the investment return period was less than 1/3 years. Density functional theory analysis confirmed that four nitrogen atoms would be involved in the coordination complex and thus a structure involving two five-membered rings could be achieved. The X-ray photoelectron spectra confirmed the involvement of nitrogen atoms,implying a coordination ratio of approximately 1:1. | Xuewen Tao Fuqiang Liu Zhiping Bai Dongyang Wei Xiaopeng Zhang Junfei Wang Jie Gao Xiaowen Sun Baohua Li Chenghui Li Aimin Li | 2016 | Journal of Environmental Sciences2016,28,10: | 3 |

| 13 | Improving crop drought resistance with plant growth regulators and rhizobacteria: Mechanisms, applications, and perspectives显示文摘Drought is one of the main abiotic stresses that cause crop yield loss.Improving crop yield under drought stress is a major goal of crop breeding,as it is critical to food security.The mechanism of plant drought resistance has been well studied,and diverse drought resistance genes have been identified in recent years,but transferring this knowledge from the laboratory to field production remains a significant challenge.Recently,some new strategies have become research frontiers owing to their advantages of low cost,convenience,strong field operability,and/or environmental friendliness.Exogenous plant growth regulator(PGR)treatment and microbe-based plant biotechnology have been used to effectively improve crop drought tolerance and preserve yield under drought stress.However,our understanding of the mechanisms by which PGRs regulate plant drought resistance and of plant-microbiome interactions under drought is still incomplete.In this review,we summarize these two strategies reported in recent studies,focusing on the mechanisms by which these exogenous treatments regulate crop drought resistance.Finally,future challenges and directions in crop drought resistance breeding are discussed. | Hui Zhang Xiaopeng Sun Mingqiu Dai | 2022 | Plant Communications2022,3,1: | 3 |

| 15 | Landscape Pattern Analysis of International Livable Communities Based on Satellite Images of Wenjiang District, Chengdu City显示文摘This paper used Google Earth satellite maps of Wenjiang District, Chengdu City in 2008, 2012 and 2015 as basic data sources, and field investigation data in recent years, and employed Photoshop and Auto CAD to analyze landscape pattern of urban and suburban areas of Wenjiang District—the international livable communities. The results showed that urban forest patches accounted for the absolute dominance in the study area, the overall landscape fragmentation index in 2008 was 0.0054, landscape diversity index 1.3603, landscape dominance index 0.2937, and evenness index 0.8452. From 2008 to 2012, patch density index reduced by 7.04, landscape fragmentation index increased by 0.0014, diversity index reduced by 0.043, evenness index reduced by 0.0269, landscape dominance index increased by 0.0027. From 2012 to 2015, patch density index increased by 1.22, landscape fragmentation index kept stable, diversity index reduced by 0.024, evenness index reduced by 0.0149, landscape dominance index increased by 0.0196. Through analyzing quantitative indexes of urban landscape pattern, and exploring basic features of the international livable communities from the perspective of landscape eco-pattern, this paper put forward suggestions for city management and green space system protection of Wenjiang as the references for the future researches on maintenance and operation of landscape eco-pattern. | ZHONG Qiu SHAO Xiaopeng SHI Jinan SUN Ying JIANG Xinyan LI Hanyang LI Qing | 2015 | Journal of Landscape Research2015,7,4: | 3 |
| 16 | Transsphenoidal microsurgical treatment of infradiaphragmatic craniopharyngioma显示文摘Objective Typically,the transcranial approach has been used for the treatment of craniopharyngiomas with suprasellar extension,whereas the transsphenoidal approach has been used mostly for infradiaphragmatic craniopharyngioma.Total resection of craniopharyngioma can reduce the recurrence rate,especially in young children,but it may lead to severe complications.Therefore,any benefit of the degree of resection must be weighed against the risk of complications by the surgeons.The purpose of this study was to explore the therapeutic outcome after transsphenoidal microsurgical treatment of infradiaphragmatic craniopharyngioma and share our experiences.Methods Between January 2003 and June 2013,30 patients with infradiaphragmatic craniopharyngioma underwent transsphenoidal microsurgical resection in our hospital.The neurological,visual,and endocrine functions,and extent of resection were analyzed retrospectively.Recurrence or growth of residual tumor tissue during follow-up was assessed using magnetic resonance imaging(MRI).Results Total resection was achieved in 25 patients(83.3%),subtotal resection was achieved in 4 patients(13.3%),and partial resection was achieved in 1 patient(3.4%).There were no perioperative deaths.Cerebrospinal fluid(CSF) leakage occurred in 6 patients,and among them,2 required surgical repair of the sella.New-onset postoperative diabetes insipidus(DI) developed in 8 patients.Vision and visual fields were improved at different levels in 13 out of 16 patients who had sight impediments before treatment.Tumor recurrence and regrowth was observed in 2 patients;1 patient underwent transsphenoidal reoperation,the condition of the other patient who had undergone several craniotomies grew worse over the 6-month follow-up period.Conclusion Transsphenoidal surgery is an ideal choice in treating infradiaphragmatic craniopharyngioma.The transsphenoidal approach,which preserves pituitary function and avoids damage to the hypothalamic structures and optic nerve,is associated with fewer complications than the transcranial approach and a low mortality rate. | Ting Lei Baofeng Wang Juan Chen Yu Xu Kai Shu Wei Sun Shaozheng Liu Xiaopeng Li | 2016 | Oncology and Translational Medicine2016,2,5: | 2 |
| 17 | Fast inverse covariance matrix computation based on element-order recursive method for space-time adaptive processing显示文摘Because of large computational complexity in the inverse space-time covariance matrix computation,the conventional space-time adaptive processing(STAP) is unsuitable for practical implementation. According to the block Hermitian matrix property of covariance matrix, a new element-order recursive method is proposed in this paper to calculate the inverse space-time covariance matrix for STAP weight vector. In the proposed method, the inverse space-time covariance matrix of first element-order is initially calculated recursively based on block Hermitian matrix property, and then the inverse space-time covariance matrix of high element-order is correspondingly deduced recursively based on obtained inverse covariance matrix of previous element-order.Finally, STAP weight vector is calculated based on the final inverse covariance matrix. Afterwards, a modified reduced-dimension STAP method is derived by combining the proposed method with the m-Doppler Transformation(m DT-SAP) STAP approach. Based on the simulated and the actual airborne phased array radar data, the proposed method verified that the computational complexity is much smaller than conventional STAP methods. The proposed element-order recursive method for STAP is applicable for practical airborne phased radar system. | YANG XiaoPeng SUN YuZe LIU YongXu ZENG Tao LONG Teng | 2015 | Science China(Information Sciences)2015,58,2: | 2 |
| 18 | Laser-driven plasma collider for nuclear studies显示文摘A novel method of initiating nuclear fusion reactions in a full plasma environment was suggested, and a proof-of-concept experiment was carried out with the D t D ! n t3 He reaction. In this new approach, two plasma jets generated by high-intensity lasers collide headon-head. The center-of-mass energy of the nuclei increases accordingly, and therefore, reaction products can be significantly enhanced, especially in the sub-Coulomb barrier ranges. As a result of the fusion reaction, up to 7:6 105 neutrons had been observed. This new type of ‘‘plasma collider'' could provide an innovative tool to study nuclear reactions under astrophysical conditions. | Changbo Fu Jie Bao Liming Chen Jianjun He Long Hou Liang Li Yanfei Li Yutong Li Guoqian Liao Yongjoo Rhee Yang Sun Shiwei Xu Dawei Yuan Xiaopeng Zhang Gang Zhao Jiarui Zhao Baojun Zhu Jianqiang Zhu Jie Zhang | 2015 | Science Bulletin2015,60,13: | 2 |
