| 1 | Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world. | Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong | 2022 | Science China(Life Sciences)2022，65，9： | 9 |
| 2 | Factors affecting genomic selection revealed by empirical evidence in maize显示文摘Genomic selection(GS) as a promising molecular breeding strategy has been widely implemented and evaluated for plant breeding, because it has remarkable superiority in enhancing genetic gain, reducing breeding time and expenditure, and accelerating the breeding process. In this study the factors affecting prediction accuracy(rMG) in GS were evaluated systematically, using six agronomic traits(plant height, ear height, ear length, ear diameter,grain yield per plant and hundred-kernel weight) evaluated in one natural and two biparental populations. The factors examined included marker density, population size, heritability,statistical model, population relationships and the ratio of population size between the training and testing sets, the last being revealed by resampling individuals in different proportions from a population. Prediction accuracy continuously increased as marker density and population size increased and was positively correlated with heritability; rMGshowed a slight gain when the training set increased to three times as large as the testing set. Low predictive performance between unrelated populations could be attributed to different allele frequencies, and predictive ability and prediction accuracy could be improved by including more related lines in the training population. Among the seven statistical models examined, including ridge regression best linear unbiased prediction(RR-BLUP), genomic BLUP(GBLUP), Bayes A, Bayes B, Bayes C, Bayesian least absolute shrinkage and selection operator(Bayesian LASSO), and reproducing kernel Hilbert space(RKHS), the RKHS and additive-dominance model(Add + Dom model) showed credible ability for capturing non-additive effects, particularly for complex traits with low heritability. Empirical evidence generated in this study for GS-relevant factors will help plant breeders to develop GS-assisted breeding strategies for more efficient development of varieties. | Xiaogang Liu Hongwu Wang Hui Wang Zifeng Guo Xiaojie Xu Jiacheng Liu Shanhong Wang Wen-Xue Li Cheng Zou Boddupalli M.Prasanna Michael S.Olsen Changling Huang Yunbi Xu | 2018 | The Crop Journal2018，6，4： | 8 |

| 4 | Development of high-resolution multiple-SNP arrays for genetic analyses and molecular breeding through genotyping by target sequencing and liquid chip显示文摘Genotyping platforms,as critical supports for genomics,genetics,and molecular breeding,have been well implemented at national institutions/universities in developed countries and multinational seed companies that possess high-throughput,automatic,large-scale,and shared facilities.In this study,we integrated an improved genotyping by target sequencing(GBTS)system with capture-in-solution(liquid chip)technology to develop a multiple single-nucleotide polymorphism(mSNP)approach in which mSNPs can be captured from a single amplicon.From one 40K maize mSNP panel,we developed three types of markers(40K mSNPs,251K SNPs,and 690K haplotypes),and generated multiple panels with various marker densities(1K–40K mSNPs)by sequencing at different depths.Comparative genetic diversity analysis was performed with genic versus intergenic markers and di-allelic SNPs versus non-typical SNPs.Compared with the one-amplicon-one-SNP system,mSNPs and within-mSNP haplotypes are more powerful for genetic diversity detection,linkage disequilibrium decay analysis,and genome-wide association studies.The technologies,protocols,and application scenarios developed for maize in this study will serve as a model for the development of mSNP arrays and highly efficient GBTS systems in animals,plants,and microorganisms. | Zifeng Guo Quannv Yang Feifei Huang Hongjian Zheng Zhiqin Sang Yanfen Xu Cong Zhang Kunsheng Wu Jiajun Tao Boddupalli MPrasanna Michael SOlsen Yunbo Wang Jianan Zhang Yunbi Xu | 2021 | Plant Communications2021，2，6： | 5 |
| 5 | Analysis on Collapse Strength of Casing Wear显示文摘Carrying capacity of the casing will reduce after the casing is worn, which seriously affects the subsequent well drilling, well completion, oil extraction and well repair. A lot of researches on calculation of casing wear collapse strength have been done, but few of them focus on collapsing failure mechanism, and influencing factors and law of collapse strength. So, significant difference between estimated value and actual value of collapse strength comes into being. By theoretical analysis, numerical simulation and actual test, the collapsing failure mechanism of casing wear as well as the influencing factors and laws of collapse strength are investigated, and the investigation results show that collapse of crescent casing wear belongs to 'three hinged' instability. The severely-worn position on the casing is yielded into the plastic zone first then deformed greatly, which causes the plastic instability of the whole structure. The casing wear collapse strength presents changes of exponent, power function and linear trend with the residual casing wall thickness, wear radius and axial load, respectively. When the flexibility is less than 10°/30 m, the borehole bending has less impact on casing collapse strength. Thus, the computation model for the casing wear collapsing strength is established by introducing wear radius coefficient and casing equivalent yield strength, at the same time, the model is tested. The test results show that the relative error for the computation model is less than 5%. The research results provide a basis for design of the casing string strength and evaluation of down-hole safety. | LIANG Erguo LI Zifeng HAN Yong LI Guoqin GUO Peipei | 2013 | Chinese Journal of Mechanical Engineering2013，26，3： | 3 |
| 6 | Hydrogen-induced Modification in the Deformation and Fracture of a Precipitation-hardened Fe-Ni Based Austenitic Alloy显示文摘Hydrogen-induced modification in the deformation and fracture of a precipitation-hardened Fe e Ni based austenitic alloy has been investigated in the present study by means of thermal hydrogen charging experiment, tensile tests, scanning electron microscopy(SEM) and transmission electron microscopy(TEM). It is found that the g0 particles are subjected to the multiple shearing by dislocations during plastic deformation,which promotes the occurrence of the dislocation planar slip. Moreover, the alloy will be enhanced by hydrogen resulting in the formation of strain localization at macroscale. So, the mechanisms of deformation and fracture in the alloy have been proposed in terms of serious hydrogen-induced planar slip at microscale which can lead to macroscopic strain localization. | Mingjiu Zhao Zifeng Guo Shenghu Chen Hao Liang Lijian Rong | 2014 | Journal of Materials Science & Technology2014，30，11： | 1 |

| 9 | Ultra-antifreeze,ultra-stretchable,transparent,and conductive hydrogel for multi-functional flexible electronics as strain sensor and triboelectric nanogenerator显示文摘Conductive hydrogels have become one of the most promising candidates for flexible electronics due to their excellent mechanical flexibility,durability of deformation,and good electrical conductivity.However,in real applications,severe environments occur frequently,such as extremely cold weather.General hydrogels always lack anti-freeze and anti-dehydration abilities.Consequently,the functions of electronic devices based on traditional hydrogels will quickly fail in extreme environments.Therefore,the development of environmentally robust hydrogels that can withstand extremely low temperatures,overcome dehydration,and ensure the stable operation of electronic devices has become increasingly important.Here,we report a kind of graphene oxide(GO)incorporated polyvinyl alcohol-polyacrylamide(PVA-PAAm)double network hydrogel(GPPDhydrogel)which shows excellent anti-freeze ability.The GPPD-hydrogel exhibits not only good flexibility and ultra-high stretchability up to 2,000%,but ensures a high sensitivity when used as the strain sensor at−50°C.More importantly,when serving as the electrode of a sandwich-structural triboelectric nanogenerator(TENG),the GPPD-hydrogel endows the TENG high and stable output performances even under−80°C.Besides,the GPPD-hydrogel is demonstrated long-lasting moisture retention over 100 days.The GPPD-hydrogel provides a reliable and promising candidate for the new generation of wearable electronics. | Xinhuan Dai Yong Long Bing Jiang Wenbin Guo Wei Sha Jiangwen Wang Zifeng Cong Jiwei Chen Bingjun Wang Weiguo Hu | 2022 | Nano Research2022，15，6： | 1 |

| 13 | Laser-induced porous graphene on Polyimide/PDMS composites andits kirigami-inspired strain sensor显示文摘The laser-induced porous graphene(LIG)prepared in a straightforward fabrication method is presented,and its applications in stretchable strain sensors to detect the applied strain are also explored.The LIGformed on the polyimide/polydimethylsiloxane(PI/PDMS)composite exhibits a naturally high stretchabil-ity(over 30%),bypassing the transfer printing process compared to the one prepared by laser scribing onPI films.The PI/PDMS composite with LIG shows tunable mechanical and electronic performances withdifferent PI particle concentrations in PDMS.The good cyclic stability and almost linear response of theprepared LIG’s resistance with respect to tensile strain provide its access to wearable electronics.To im-prove the PDMS/PI composite stretchability,we designed and optimized a kirigami-inspired strain sensorwith LIG on the top surface,dramatically increasing the maximum strain value that in linear response toapplied strain from 3%to 79%. | Hao Wang Zifeng Zhao Panpan Liu Xiaogang Guo | 2021 | Theoretical & Applied Mechanics Letters2021，11，2： | 0 |
| 14 | Engineering Sodium Metal Anode with Sodiophilic Bismuthide Penetration for Dendrite-Free and High-Rate Sodium-Ion Battery显示文摘Sodium(Na)metal batteries with a high volumetric energy density that can be operated at high rates are highly desirable.However,an uneven Na-ion migration in bulk Na anodes leads to localized deposition/dissolution of sodium during high-rate plating/stripping behaviors,followed by severe dendrite growth and loose stacking.Herein,we engineer the Na hybrid anode with sodiophilic Na_(3)Bi-penetration to develop the abundant phase-boundary ionic transport channels.Compared to intrinsic Na,the reduced adsorption energy and ion-diffusion barrier on Na_(3)Bi ensure even Na^(+)nucleation and rapid Na^(+)migration within the hybrid electrode,leading to uniform deposition and dissolution at high current densities.Furthermore,the bismuthide enables compact Na deposition within the sodiophilic framework during cycling,thus favoring a high volumetric capacity.Consequently,the obtained anode was endowed with a high current density(up to 5 mA∙cm^(−2)),high areal capacity(up to 5 mA∙h∙cm^(−2)),and long-term cycling stability(up to 2800 h at 2 mA∙cm^(−2)). | Wanyu Zhao Min Guo Zhijun Zuo Xiaoli Zhao Huanglin Dou Yijie Zhang Shiying Li Zichen Wu Yayun Shi Zifeng Ma Xiaowei Yang | 2022 | Engineering2022，8，4： | 0 |
| 15 | Luminescent d-f transition Yb(Ⅱ)-containing azacryptates with high photoluminescence quantum yields显示文摘Emission tunable d-f transition lanthanide complexes have wide applications in many fields such as lighting and photoredox catalysis.Compared with Ce(Ⅲ)and Eu(Ⅱ)complexes,which have achieved near-unity photoluminescence quantum yields(PLQYs),Yb(Ⅱ)complexes still suffer from low reported PLQYs not exceeding 10%.In this work,two luminescent Yb(Ⅱ)-containing azacryptates YbI_(2)-N8M6(N8M6=4,7,13,16,21,24-hexamethyl-1,4,7,10,13,16,21,24-octaazabicyclo[8.8.8]hexacosane)and YbI2-N8E6(N8E6=4,7,13,16,21,24-hexaethyl-1,4,7,10,13,16,21,24-octaazabicyclo[8.8.8]hexacosane)were synthesized and characterized.YbI2-N8M6 in solid powder exhibits blue emission with a maximum emission wavelength(λm)of 464 nm and a PLQY of 76%,while YbI_(2)-N8E6 in solid powder exhibits green emission with a λ_(m) of 537 nm and a PLQY up to93%.Moreover,YbI_(2)-N8M6 exhibits mechanochromic property,showing an emission color change from deep-blue to cyan under mechanical grinding.These results will inspire the studies about luminescent Yb(Ⅱ)complexes and their further applications. | Wenchao Yan Zifeng Zhao Gang Yu Hao Qi Ruoyao Guo Nanlong Zheng Zuqiang Bian Zhiwei Liu | 2023 | Science China Chemistry2023，66，6： | 0 |
| 16 | Urban traffic modeling and pattern detection using online map vendors and self-organizing maps显示文摘Typical traffic modeling approaches,such as network-based methods and simulation models,have been shown inadequate for urban-scale studies due to the fidelity issue of models.As a go-around,data-driven models have received increasing attention recently.However,most data-driven methods have been restricted by their data source and cannot be scaled up to manage urban-and regional-scale studies.Regarding this issue,this research proposes a pipeline that collects traffic data from online map vendors to bypass data limitations for large-scale studies.The study consists of two experiments:1)recognizing the dominant traffic patterns of cities and 2)site-specific predictions of typical traffic or the most probable locations of patterns of interests.The experiments were conducted on 32 Swiss cities using traffic data that were collected for a two-month period.The results show that dominant patterns can be extracted from the temporal traffic data,and similar patterns exist not only in various parts of a city but also in different cities.Moreover,the results reveal that a country-level lockdown decreased traffic congestions in regional highways but increased those connections near the city centers and the country borders. | Zifeng Guo Biao Li Ludger Hovestadt | 2021 | Frontiers of Architectural Research2021，10，4： | 0 |
| 17 | Targeting cancer cell plasticity by HDAC inhibition to reverse EBV-induced dedifferentiation in nasopharyngeal carcinoma显示文摘Application of differentiation therapy targeting cellular plasticity for the treatment of solid malignancies has been lagging.Nasopharyngeal carci noma(NPC)is a distinctive cancer with poor differe ntiatio n and high prevalenee of Epstein-Barr virus(EBV)infection.Here,we show that the expressi on of EBV latent protein LMP1 in duces dediffere ntiated and stem-like status with high plasticity through the transcriptional inhibition of CEBPA.Mechanistically,LMP1 upregulates STAT5A and recruits HDAC 1/2 to the CEBPA locus to reduce its histone acetylation.HDAC inhibition restored CEBPA expression,reversing cellular dedifferentiation and stem-like status in mouse xeno graft models.These fin dings provide a novel mecha nistic epigenetic-based in sight into virus-induced cellular plasticity and propose a promising concept of differentiation therapy in solid tumor by using HDAC inhibitors to target cellular plasticity. | Jiajun Xie Zifeng Wang Wenjun Fan Youping Liu Fang Liu Xiangbo Wan Meiling Liu Xuan Wang Deshun Zeng Van Wang Bin He Min Yan Zijian Zhang Mengjuan Zhang Zhijie Hou Chunli Wang Zhijie Kang Wenfeng Fang Li Zhang Eric W-F Lam Xiang Guo Jinsong Yan Yixin Zeng Mingyuan Chen Quentin Liu | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 0 |
| 18 | The wheat sucrose synthase gene TaSus1 is a determinant of grain number per spike显示文摘Some haplotypes of the sucrose synthase gene TaSus1 are associated with thousand-grain weight(TGW)in wheat(Triticum aestivum L.).However,no mutations have been identified within the gene to test this association.The effects of TaSus1 on grain number per spike(GNS)also are largely unknown.Our previous genome-wide association study identified TaSus-A1 as a candidate gene controlling fertile spikelet number per spike(FSN).In the present study,we generated two independent mutants for the three TaSus1 homoeologs by CRISPR/Cas9-mediated genome editing.The triple mutants displayed lower FSN,GNS,grain number per spikelet(GNST),and TGW than wild-type plants.In 306 hexaploid wheat accessions,two single-nucleotide polymorphisms in TaSus-A1 contributed differently to GNS.Introgression of the two alleles into a wheat genetic background confirmed their effects.The alleles differed in geographical distribution among the accessions. | Liping Shen Lili Zhang Changbin Yin Xiaowan Xu Yangyang Liu Kuocheng Shen He Wu Zhiwen Sun Ke Wang Zhonghu He Xueyong Zhang Chenyang Hao Jian Hou Aoyue Bi Xuebo Zhao Daxing Xu Botao Ye Xuchang Yu Ziying Wang Danni Liu Yuanfeng Hao Fei Lu Zifeng Guo | 2024 | The Crop Journal2024，12，1： | 0 |
| 19 | Using Recurrent Neural Network Structure and Multi-Head Attention with Convolution for Fraudulent Phone Text Recognition显示文摘Fraud cases have been a risk in society and people’s property security has been greatly threatened.In recent studies,many promising algorithms have been developed for social media offensive text recognition as well as sentiment analysis.These algorithms are also suitable for fraudulent phone text recognition.Compared to these tasks,the semantics of fraudulent words are more complex and more difficult to distinguish.Recurrent Neural Networks(RNN),the variants ofRNN,ConvolutionalNeuralNetworks(CNN),and hybrid neural networks to extract text features are used by most text classification research.However,a single network or a simple network combination cannot obtain rich characteristic knowledge of fraudulent phone texts relatively.Therefore,a new model is proposed in this paper.In the fraudulent phone text,the knowledge that can be learned by the model includes the sequence structure of sentences,the correlation between words,the correlation of contextual semantics,the feature of keywords in sentences,etc.The new model combines a bidirectional Long-Short Term Memory Neural Network(BiLSTM)or a bidirectional Gate Recurrent United(BiGRU)and a Multi-Head attention mechanism module with convolution.A normalization layer is added after the output of the final hidden layer.BiLSTM or BiGRU is used to build the encoding and decoding layer.Multi-head attention mechanism module with convolution(MHAC)enhances the ability of the model to learn global interaction information and multi-granularity local interaction information in fraudulent sentences.A fraudulent phone text dataset is produced by us in this paper.The THUCNews data sets and fraudulent phone text data sets are used in experiments.Experiment results show that compared with the baseline model,the proposed model(LMHACL)has the best experiment results in terms of Accuracy,Precision,Recall,and F1 score on the two data sets.And the performance indexes on fraudulent phone text data sets are all above 0.94. | Junjie Zhou Hongkui Xu Zifeng Zhang Jiangkun Lu Wentao Guo Zhenye Li | 2023 | Computer Systems Science & Engineering2023，46，8： | 0 |
| 20 | Improvement in hydrogen storage performance of Mg by mechanical grinding with molten salt etching Ti_(3)C_(2)Cl_(x)显示文摘Mg-based materials are currently a hot research topic as hydrogen storage materials due to their considerable theoretical hydrogen storage capacity.However,the kinetic performance of hydrogen absorption and desorption of Mg is too slow and requires high temperature,which seriously hinders the application of this material.MXene is a new type of two-dimensional material with significant role in improving thermodynamics and kinetics.In this experiment,a two-dimensional layered MXene containing Cl functional group was prepared by molten salt etching using the Ti-containing MAX phase as the raw material.Then different ratios of Ti_(3)C_(2)Cl_(x) were uniformly dispersed onto the surface of Mg by high energy ball milling.The samples were characterized by hydrogen absorption and desorption kinetics,SEM,XRD,XPS,and DSC to investigate the effect of Ti_(3)C_(2)Cl_(x) on the hydrogen absorption and desorption performance of Mg.The onset hydrogen absorption temperature can be reduced to room temperature and the hydrogen release temperature is reduced by 200℃ by doping Ti_(3)C_(2)Cl_(x).And there is also 5.4wt%hydrogen storage in the isothermal hydrogen absorption test at 400℃.The results of DSC demonstrate that the Ea of Mg+15wt%Ti_(3)C_(2)Cl_(x) was reduced by 12.6%compared to pristine Mg.TheΔH is almost invariable.The results of XPS show that the presence of multivalent Ti promotes electron transfer and thus improves the conversion between Mg^(2+)/Mg and H^(−)/H.This study provides a guideline for further improving the hydrogen absorption and desorption performance of Mg-based hydrogen storage materials. | Shuaicheng Hu Lijun Lv Guo Yang Wei Liu Hong Miao Honghui Cheng Xingbo Han Zifeng Lin | 2023 | Progress in Natural Science:Materials International2023，33，2： | 0 |
