| 1 | Phytophthora sojae Effector PsAvh240 Inhibits Host Aspartic Protease Secretion to Promote Infection显示文摘Plants secrete defense molecules into the extracellular space (the apoplast) to combat attacking microbes. However, the mechanisms by which successful pathogens subvert plant apoplastic immunity remain poorly understood. In this study, we show that PsAvh240, a membrane-localized effector of the soybean pathogen Phytophthora sojae, promotes P. sojae infection in soybean hairy roots. We found that PsAvh240 interacts with the soybean-resistant aspartic protease GmAP1 in planta and suppresses the secretion of GmAP1 into the apoplast. By solving its crystal structure we revealed that PsAvh240 contain six a helices and two WY motifs. The first two a helices of PsAvh240 are responsible for its plasma membrane-localization and are required for PsAvh240's interaction with GmAP1. The second WY motifs of two PsAvh240 molecules form a handshake arrangement resulting in a handshake-like dimer. This dimerization is required for the effector's repression of GmAP1 secretion. Taken together, these data reveal that PsAvh240 localizes at the plasma membrane to interfere with GmAP1 secretion, which represents an effective mechanism by which effector proteins suppress plant apoplastic immunity. | Baodian Guo Haonan Wang Bo Yang Wenjing Jiang Maofeng Jing Haiyang Li Yeqiang Xia Yuanpeng Xu Qinli Hu Fangfang Wang Feng Yu Yan Wang Wenwu Ye Suomeng Dong Weiman Xing Yuanchao Wang | 2019 | Molecular Plant2019,12,4: | 12 |
| 2 | A new distinct geminivirus causes soybean stay-green disease显示文摘Dear Editor,Plant viruses make up almost half of the plant disease-causing pathogens,affecting crop yields and the global economy(Savary et al.,2019).Soybean(Glycine max)is one of the most valuable legume crops in the world,supplying 25%of the global edible oil and two-thirds of the global concentrated protein for livestock feeding.Recently,the outbreak of soybean stay-green syndrome with delayed leaf senescence(stay-green),flat pods,and increased number of abnormal seeds has swept the soybean production in the Huang-Huai-Hai region of China,resulting in huge yield losses(Xu et al.,2019).This disease has become an epidemic and prominent problem in soybean production and is still expanding its geography,including North America,posing a serious threat to soybean production(Harbach et al.,2016;Zhang et al.,2016;Li et al.,2019).However,the cause of soybean stay-green syndrome remains obscure. | Ruixiang Cheng Ruoxin Mei Rong Yan Hongyu Chen Dan Miao Lina Cai Jiayi Fan Gairu Li Ran Xu Weiguo Lu Yu Gao Wenwu Ye Shuo Su Tianfu Han Junyi Gai Yuanchao Wang Xiaorong Tao Yi Xu | 2022 | Molecular Plant2022,15,6: | 6 |
| 3 | In-situ surface decoration of RuO_(2) nanoparticles by laser ablation for improved oxygen evolution reaction activity in both acid and alkali solutions显示文摘Improving the OER activity of noble metal-based materials is of profound importance to minimize the usage of noble metals and lower the cost.Here,we report considerable improvement on the catalytic activity of RuO_(2) particles for OER in both alkali and acid environments.The RuO_(2) nanoparticles were treated with a method of pulse laser ablation.Numerous Ru and RuO_(2) clusters were generated at the surface of RuO_(2) nanoparticles after the laser ablation,forming a lychee-shaped morphology.The larger pulse energy RuO_(2) nanoparticles are treated with,the better the OER activity can be.DFT calculations shows that the surface tension induced by the lychee-shaped morphology benefits the OER performance.Our best sample gives an overpotential of 172 mV(at 10 mA cm^(-2))and a Tafel slope of 53.5 mV dec^(-1) in KOH,while an overpotential of 219 mV and a Tafel slope of 44.9 mV dec^(-1) in H_(2)SO_(4),which are of topclass results.This work may inspire a new way to develop high-performance electrocatalysts for OER. | Zongpeng Wang Beibei Xiao Zhiping Lin Shijie Shen Aijiao Xu Zexin Du Yuchao Chen Wenwu Zhong | 2021 | Journal of Energy Chemistry2021,30,3: | 4 |
| 4 | Distributed fixed step-size algorithm for dynamic economic dispatch with power flow limits显示文摘In this study,a discrete-time distributed algorithm is proposed for solving the dynamic economic dispatch problem with active power flow limits and transmission line loss.To avoid the communication burden and implement the algorithm in a favorably distributed manner,the splitting method is used to bypass the centralized updating of the algorithm’s parameters,which is unavoidable when implementing conventional Lagrangian methods.The use of a fixed step-size and distributed update enhances the applicability of the algorithm.The performance and effectiveness of the proposed distributed algorithm are verified via numerical studies on the IEEE 14-bus system. | Kun WANG Zao FU Qian XU Duxin CHEN Lei WANG Wenwu YU | 2021 | Science China(Information Sciences)2021,64,1: | 2 |
| 5 | Deformation nanomechanics and dislocation quantification at the atomic scale in nanocrystalline magnesium显示文摘Classical molecular dynamics(MD)simulation method is employed to study the uniaxial tensile deformation of nanocrystalline magnesium(Mg)of varying grain size levels.The mean grain size of the sample is varied from 6.4 nm to 45 nm,with each sample containing about 43 million atoms in the modeling system.The deformation nanomechanics reveals two distinct deformation mechanisms.For larger grain-sized samples,dislocation dominated deformation is observed while,in smaller grain-sized samples,grain boundary-based mechanisms such as grain boundary sliding,grain boundary rotation are observed.The transition of normal and inverse Hall-Petch relation occurs at around lOnm.Dislocation density quantification shows that the dislocation density in the sample drastically reduces with decreasing grain size.Elastic modulus of nanocrystalline Mg with mean grain size above 20 nm remains comparable to that of the coarse-grained polycrystalline bulk,followed by a rapid reduction below that grain size.The present work reveals the nanomechanics of nanocrystalline Mg,facilitating the design and development of Mg-based nanostructured alloys with superior mechanical properties. | Md.Shahrier Hasan Rachell Lee Wenwu Xu | 2020 | Journal of Magnesium and Alloys2020,8,4: | 2 |
| 6 | First Discovery of Hadean Xenocrystal Zircons from Granitic Gneisses in the Northern Dabie Orogen显示文摘Objective Geological records of Earth history in the Hadean(>4.0 Ga)are critical for understanding the earliest evolution of the planet’s continental crust.Unfortunately,investigation of such proto-continental crust,including its formation mechanism and evolution,has been extremely limited due to the scarcity of Hadean terranes,because most ancient crustal records have been destroyed during subsequent geological processes. | QIU Xiaofei DENG Xin JIANG Tuo XU Qiong YANG Wenwu | 2021 | Acta Geologica Sinica(English Edition)2021,95,5: | 2 |

| 8 | An imputed whole-genome sequence-based GWAS approach pinpoints causal mutations for complex traits in a specific swine population显示文摘Sequencing-based genome-wide association studies(GWAS) have facilitated the identification of causal associations between genetic variants and traits in diverse species. However, it is cost-prohibitive for the majority of research groups to sequence a large number of samples. Here, we carried out genotype imputation to increase the density of single nucleotide polymorphisms in a large-scale Swine F;population using a reference panel including 117 individuals, followed by a series of GWAS analyses. The imputation accuracies reached 0.89 and 0.86 for allelic concordance and correlation, respectively. A quantitative trait nucleotide(QTN) affecting the chest vertebrate was detected directly, while the investigation of another QTN affecting the residual glucose failed due to the presence of similar haplotypes carrying wild-type and mutant allelesin the reference panel used in this study. A high imputation accuracy was confirmed by Sanger sequencing technology for the most significant loci. Two candidate genes,CPNE5 and MYH3, affecting meat-related traits were proposed. Collectively, we illustrated four scenarios in imputation-based GWAS that may be encountered by researchers, and our results will provide an extensive reference for future genotype imputation-based GWAS analyses in the future. | Guorong Yan Xianxian Liu Shijun Xiao Wenshui Xin Wenwu Xu Yiping Li Tao Huang Jiangtao Qin Lei Xie Junwu Ma Zhiyan Zhang Lusheng Huang | 2022 | Science China(Life Sciences)2022,65,4: | 2 |
| 9 | Pollen-like self-supported FeIr alloy for improved hydrogen evolution reaction in acid electrolyte显示文摘Ir is recognized as efficient catalyst for hydrogen evolution reaction(HER).The high price,however,has hindered its application in the production of hydrogen.In this work,we prepared the self-supported FeIr alloy nanoparticles,taking advantage of solid-state synthesis method.The as-prepared FeIr alloy possesses a novel morphology of pollen,which is consist of smaller FeIr nanoparticles.DFT calculations reveal that the change of the free Gibbs for Ir is negative after the adsorption of active H,while it is positive for the case of Fe.Thus,the alloying of Fe and Ir not only effectively reduces the cost,but also can achieve more adequate adsorption of active H species.Benefitting from this,the as-prepared FeIr alloy nanoparticle exhibits superior HER performance with an overpotential of 19 m V at a current density of 10 m V/cm^(2)and a Tafel slope of 32 m V/dec,when tested in 0.5 M H_(2)SO_(4),better than pure Ir and Pt/C.This work paves the way to the exploration of efficient alloy electrocatalysts for HER. | Shengyu Ma Jun Deng Yaping Xu Weiying Tao Xiaoqi Wang Zhiping Lin Qinghua Zhang Lin Gu Wenwu Zhong | 2022 | Journal of Energy Chemistry2022,31,3: | 1 |
| 10 | Structural variation and parallel evolution of apomixis in citrus during domestication and diversification显示文摘Apomixis,or asexual seed formation,is prevalent in Citrinae via a mechanism termed nucellar or adventitious embryony.Here,multiple embryos of a maternal genotype form directly from nucellar cells in the ovule and can outcompete the developing zygotic embryo as they utilize the sexually derived endosperm for growth.Whilst nucellar embryony enables the propagation of clonal plants of maternal genetic constitution,it is also a barrier to effective breeding through hybridization.To address the genetics and evolution of apomixis in Citrinae,a chromosome-level genome of the Hongkong kumquat(Fortunella hindsii)was assembled following a genome-wide variation map including structural variants(SVs)based on 234 Citrinae accessions.This map revealed that hybrid citrus cultivars shelter genome-wide deleterious mutations and SVs into heterozygous states free from recessive selection,which may explain the capability of nucellar embryony in most cultivars during Citrinae diversification.Analyses revealed that parallel evolution may explain the repeated origin of apomixis in different genera of Citrinae.Within Fortunella,we found that apomixis of some varieties originated via introgression.In apomictic Fortunella,the locus associated with apomixis contains the FhRWP gene,encoding an RWP-RK domain-containing protein previously shown to be required for nucellar embryogenesis in Citrus.We found the heterozygous SV in the FhRWP and CitRWP promoters from apomictic Citrus and Fortunella,due to either two or three miniature inverted transposon element(MITE)insertions.A transcription factor,FhARID,encoding an AT-rich interaction domain-containing protein binds to the MITEs in the promoter of apomictic varieties,which facilitates induction of nucellar embryogenesis.This study provides evolutionary genomic and molecular insights into apomixis in Citrinae and has potential ramifications for citrus breeding. | Nan Wang Xietian Song Junli Ye Siqi Zhang Zhen Cao Chenqiao Zhu Jianbing Hu Yin Zhou Yue Huang Shuo Cao Zhongjie Liu Xiaomeng Wu Lijun Chai Wenwu Guo Qiang Xu Brandon S.Gaut Anna M.G.Koltunow Yongfeng Zhou Xiuxin Deng | 2022 | National Science Review2022,9,10: | 1 |
| 11 | Ultralow-temperature assisted synthesis of single platinum atoms anchored on carbon nanotubes for efficiently electrocatalytic acidic hydrogen evolution显示文摘Although platinum(Pt) is highly active for hydrogen evolution reaction(HER)[1], it is crucial to explore the effective approach for minimizing the Pt loading amount in the practical application. Herein, one ultralow-temperature solution reduction approach is developed to anchor atomically dispersed Pt atoms on carbon nanotubes(Pt-CNTs), which decelerates the diffusion rate of Pt Cl2-6 ion reached onto the carbon nanotubes and lowers the free energy of Pt atoms in the solution to reduce the probability of the Pt aggregation. The obtained Pt-CNTs exhibits a low overpotential of 41 mV@10 mA cm^(-2) for HER in acidic media. The calculation results revealed that the improvement of the electrocatalytic activity is contributed by the interaction between CNTs and Pt atoms, which descreases the the Pt d band cneter referred to the Fermi level and lowers the Gibbs free energy of H*adsorption. This work may provide one easy and convenient strategy for the large-scale use of Pt catalysts in practical applications. | Wenwu Zhong Wenguang Tu Zongpeng Wang Zhiping Lin Aijiao Xu Xiufang Ye Dongchu Chen Beibei Xiao | 2020 | Journal of Energy Chemistry2020,29,12: | 1 |
| 12 | Whole-genome sequence-based association study for immune cells in an eight-breed pig heterogeneous population显示文摘Pigs are an important domestic animal for meat production and animal models for biomedical research such as research on infectious diseases(Meurens et al.,2012).Immune cells,including T cells,B cells,monocytes,and macrophages,are among the major indicators of immune status in health and disease.Revealing the genetic basis of immune cell phenotypes would be helpful for improving the immunity of pigs genetically and reducing the disease occurrence,antibiotic usage. | Qing Zhang Jing Li Yifeng Zhang Huanfa Gong Zhimin Zhou Wenwu Xu Zhongzi Wu Yingchun Sun Tao Jiang Ziqi Ling Shijun Xiao Lusheng Huang Bin Yang | 2022 | Journal of Genetics and Genomics2022,49,11: | 1 |

| 14 | DeceFL:a principled fully decentralized federated learning framework显示文摘Traditional machine learning relies on a centralized data pipeline for model training in various applications;however,data are inherently fragmented.Such a decentralized nature of databases presents the serious challenge for collaboration:sending all decentralized datasets to a central server raises serious privacy concerns.Although there has been a joint effort in tackling such a critical issue by proposing privacy-preserving machine learning frameworks,such as federated learning,most state-of-the-art frameworks are built still in a centralized way,in which a central client is needed for collecting and distributing model information(instead of data itself)from every other client,leading to high communication burden and high vulnerability when there exists a failure at or an attack on the central client.Here we propose a principled decentralized federated learning algorithm(DeceFL),which does not require a central client and relies only on local information transmission between clients and their neighbors,representing a fully decentralized learning framework.It has been further proven that every client reaches the global minimum with zero performance gap and achieves the same convergence rate O(1=T)(where T is the number of iterations in gradient descent)as centralized federated learning when the loss function is smooth and strongly convex.Finally,the proposed algorithm has been applied to a number of applications to illustrate its effectiveness for both convex and nonconvex loss functions,time-invariant and time-varying topologies,as well as IID and Non-IID of datasets,demonstrating its applicability to a wide range of real-world medical and industrial applications. | Ye Yuan Jun Liu Dou Jin Zuogong Yue Tao Yang Ruijuan Chen Maolin Wang Chuan Sun Lei Xu Feng Hua Yuqi Guo Xiuchuan Tang Xin He Xinlei Yi Dong Li Guanghui Wen Wenwu Yu Hai-Tao Zhang Tianyou Chai Shaochun Sui Han Ding | 2023 | National Science Open2023,2,1: | 1 |
| 15 | 3D Printing of Nacre-Inspired Structures with Exceptional Mechanical and Flame-Retardant Properties显示文摘Flame-retardant and thermal management structures have attracted great attention duc to the requirement of high-temperature exposure in industrial,aerospace,and thermal power fields,but the development of protoctive fire-retardant structures with complex shapes to fit arbitrary surfaces is still challenging.Herein,we reported a rotation-blade casting-assisted 3D printing process to fabricate nacre-inspired structures with exceptional mechanical and flame-retardant properties,and the relatedi fundamental mechanisms are studied.3-(Trimethoxysilyl)propyl methacrylate(TMSPMA)modified boron nitride nanoplatelets(BNs)were aligned by rotation-blade casting during the 3D printing process to build the'hrick and mortar'architecture.The 3D printed structures are more lightweight,while having higher fracture toughness than the natural nacre,which is attributed to the crack deflection,aligned BN(a-BNs)bridging,and pull-outs reinforced structures by the covalent bonding between TMSPMA grafted a-BNs and polymer matrix.Thermal conductivity is enhanced by 25.5 times compared with pure polymer and 5.8 times of anisotropy due to the interconnection of a-BNs.3D printed heat-exchange structures with vertically aligned BNs in complex shapes were demonstrated for efficient thermal control of high-power light-emitting diocles.3D printed helmet and armor with a-BNs show exceptional mechanical and fire-retardant properties,demonstrating integrated mechanical and thermal protection. | Yang Yang Ziyu Wang Qingqing He Xiangjia Li Gengxi Lu Laiming Jjiang Yushun Zeng Brandon Bethers Jie Jin Shuang Lin Siqi Xiao Yizhen Zhu Xianke Wu Wenwu Xu Qiming Wang Yong Chen | 2022 | Research2022,,2: | 1 |
| 16 | Fusarium-produced vitamin B6 promotes the evasion of soybean resistance by Phytophthora sojae显示文摘Plants can be infected by multiple pathogens concurrently in natural systems. However,pathogen–pathogen interactions have rarely been studied. In addition to the oomycete Phytophthora sojae, fungi such as Fusarium spp. also cause soybean root rot. In a 3-year field investigation, we discovered that P. sojae and Fusarium spp. frequently coexisted in diseased soybean roots. Out of 336 P. sojae–soybean–Fusarium combinations,more than 80% aggravated disease. Different Fusarium species all enhanced P. sojae infection when co-inoculated on soybean. Treatment with Fusarium secreted non-proteinaceous metabolites had an effect equal to the direct pathogen coinoculation. By screening a Fusarium graminearum mutant library, we identified Fusarium promoting factor of Phytophthora sojae infection 1(Fpp1),encoding a zinc alcohol dehydrogenase. Fpp1 is functionally conserved in Fusarium and contributes to metabolite-mediated infection promotion, in which vitamin B6(VB6) produced by Fusarium is key. Transcriptional and functional analyses revealed that Fpp1 regulates two VB6 metabolism genes, and VB6 suppresses expression of soybean disease resistance-related genes. These results reveal that co-infection with Fusarium promotes loss of P. sojae resistance in soybean, information that will inform the sustainable use of diseaseresistant crop varieties and provide new strategies to control soybean root rot. | Shuchen Wang Xiaoyi Zhang Zhichao Zhang Yun Chen Qing Tian Dandan Zeng Miao Xu Yan Wang Suomeng Dong Zhonghua Ma Yuanchao Wang Xiaobo Zheng Wenwu Ye | 2023 | Journal of Integrative Plant Biology2023,65,9: | 1 |

| 20 | Geographically varying relationships between population flows from Wuhan and COVID-19 cases in Chinese cities显示文摘The COVID-19 epidemic widely spread across China from Wuhan,Hubei Province,because of huge migration before 2020 Chinese New Year.Previous studies demonstrated that population outflows from Wuhan determined COVID-19 cases in other cities but neglected spatial hetero-geneities of their relationships.Here,we use Geographically Weighted Regression(GWR)model to investigate the spatially varying influences of outflows from Wuhan.Overall,the GWR model increases explanatory ability of outflows from Wuhan by 20%,with the adjusted R2 increasing from~0.6 of Ordinary Least Squares(OLS)models to~0.8 of GWR models.The coefficient between logarithmic of outflows from Wuhan and COVID-19 cases in other cities is generally less than 1.The sub-linear scaling relationship indicates the increasing returns of outflows was restrained,proving the epidemic was efficiently controlled outside Hubei at the beginning without obvious local transmissions.Coefficients in GWR models vary in cities.Not only cities around Wuhan but also cities having close connections with Wuhan experienced higher coefficients,showing a higher vulnerability of these cities.The secondary or multi-level trans-mission networks deserve to be further explored to fully uncover influences of migrations on the COVID-19 pandemic. | Gang Xu Wenwu Wang Dandan Lu Binbin Lu Kun Qin Limin Jiao | 2022 | Geo-Spatial Information Science2022,25,2: | 1 |
