| 1 | A journey to understand wheat Fusarium head blight resistance in the Chinese wheat landrace Wangshuibai显示文摘Fusarium head blight(FHB) or scab caused by Fusarium graminearum is a major threat to wheat production in China as well as in the world. To combat this disease, multiple efforts have been carried out internationally. In this article, we review our long-time effort in identifying the resistance genes and dissecting the resistance mechanisms by both forward and reverse genetics approaches in the last two decades. We present recent progress in resistance QTL identification, candidate functional gene discovery, marker-assisted improvement of FHB resistant varieties, and findings in investigating association of signal molecules, such as Ca^(++),SA, JA, and ET, with FHB response, with the assistance from rapidly growing genomics platforms. The information will be helpful for designing novel and efficient approaches to curb FHB. | Haiyan Jia Jiyang Zhou Shulin Xue Guoqiang Li Haisheng Yan Congfu Ran Yiduo Zhang Jinxing Shi Li Jia Xin Wang Jing Luo Zhengqiang Ma | 2018 | The Crop Journal2018，6，1： | 24 |
| 2 | 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 |
| 3 | Strengthening effect of Cu-rich phase precipitation in 18Cr9Ni3CuNbN austenitic heat-resisting steel显示文摘The Cu-containing austenitic heat-resistant steel 18Cr9Ni3CuNbN, which is being used as superheater and reheater tube material for modern ultra-super-critical (USC) power plants all over the world, has been investigated at 650 ℃ long time aging till 10 000 h. SEM, TEM and 3DAP (three dimensional atom probe) have been used to follow microstructural changes with mechanical property variations. Experimental results show that Cu-rich phase and MX precipitate in the grains as well as M 23 C 6 precipitates at grain boundaries are the main precipitation strengthening phases in this steel. Among them Cu-rich phase is the most important strengthening phase. Homogeneous distribution of very fine nano-size Cu-rich phase has been formed at very early stage of 650 ℃ aging (less than 1 h). Cu atoms gradually concentrate to Cu-rich particles and the other elements (such as Fe, Cr, Ni etc) diffuse away from Curich particles to γ-matrix with the increasing of aging time at 650 ? C. The growth rate of Cu-rich phase at 650 ℃ long time aging is very slow and the average diameters of Cu-rich phase have been determined by TEM method. Cu-rich phase keeps in about 30 nm till 650 ℃ aging for 10 000 h. It shows that nano-size Cu-rich phase precipitation strengthening can be kept for long time aging at 650 ℃ because of its excellent stability at high temperatures. According to structure stability study and mechanical properties determination results the Cu-rich phase precipitation sequence and its strengthening mechanism model have been suggested and discussed. | Chengyu CHI Hongyao YU Jianxin DONG Xishan XIE Zhengqiang CUI Xiaofang CHEN Fusheng LIN | 2011 | Acta Metallurgica Sinica(English Letters)2011，24，2： | 6 |
| 4 | A haplotype block associated with thousand-kernel weight on chromosome 5DS in common wheat(Triticum aestivum L.)显示文摘Spike number per unit area, number of grains per spike, and thousand-kernel weight(TKW) are important yield components for wheat(Triticum aestivum L.). TKW has the highest heritability among the three components. We validated 27 simple sequence repeat(SSR) loci associated with TKW in an F2:5breeding population grown in four environments. A cfd78265 bpmarker on chromosome 5DS showed the strongest association with TKW and had a significantly positive effect on TKW compared to allele cfd78259 bp, with mean increases of 5.17, 3.63, 4.11, and 5.16 g in the four environments. Markers cfd67 and cfd40 flanking cfd78 also showed significantly positive associations with TKW with increases of 5.11, 3.29, 4.31, and 4.50 g for cfd67205, and4.98, 3.49, 4.06, and 4.84 g for cfd40187 compared with cfd67203 and cfd40190in the four environments, respectively. A major quantitative trait locus for TKW spanning 2.94 c M on chromosome 5DS was detected by association mapping.Strong linkage disequilibrium(LD)(r2> 0.2) was detected Resear among the three linked markers, which formed three haplotype blocks in the F2:5breeding population. Mean TKW differences between Hap B-I and Hap B-II were 5.80, 4.41, 4.02,and 5.06 g in the four environments, respectively. Moreover,significant LD was detected only between cfd78 and cfd67 and between cfd67 and cfd40 in a germplasm collection. This study provides a base for cloning genes related to TKW on chromosome 5DS. | Yuquan Wang Chenyang Hao Jun Zheng Hongmei Ge Yang Zhou Zhengqiang Ma Xueyong Zhang | 2015 | Journal of Integrative Plant Biology2015，57，8： | 5 |
| 5 | INFLUENCES OF ANISOTROPY ON BAND GAPS OF 2D PHONONIC CRYSTAL显示文摘Band gaps of 2D phononic crystal with orthotropic cylindrical fillers embedded in the isotropic host are studied in this paper.Two kinds of periodic structures,namely,the square lattice and the triangle lattice,are considered.For anisotropic phononic crystal,band gaps not only depend on the periodic lattice but also the angle between the symmetry axis of orthotropic material and that of the periodic structure.Rotating these cylindrical fillers makes the angle changing continuously;as a result,pass bands and forbidden bands of the phononic crystal are changed.The plane wave expansion method is used to reduce the band gap problem to an eigenvalue problem.The numerical example is given for YBCO/Epoxy composites.The location and the width of band gaps are estimated for different rotating angles.The influence of anisotropy on band gaps is discussed based on numerical results. | Zhengqiang Zhan Peijun Wei 1(Department of Mathematics and Mechanics,School of Applied Science,University of Science and Technology Beijing,Beijing 100083,China) | 2010 | Acta Mechanica Solida Sinica2010，23，2： | 4 |
| 6 | Effects of loading condition on very-high-cycle fatigue behaviour and dominant variable analysis显示文摘The specimens of a high carbon chromium steel were quenched and tempered at 150°C,180°C and 300°C.Such specimens were tested via rotating bending and a push-pull type of axial loading to investigate the influences of loading condition on the behaviour of very-high-cycle fatigue(VHCF).Experimental results show the different influences of inclusion size on the fatigue life for the two loading conditions.Predominant factors and mechanism for the fine-granular-area(FGA)of crack origin were discussed.In addition,a reliability analysis based on a modified Tanaka-Mura model was carried out to evaluate the sensitivity of inclusion size,stress,and KFGA to the life of VHCF crack initiation. | LEI ZhengQiang XIE JiJia SUN ChengQi HONG YouShi | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，1： | 4 |
| 7 | Preparation of fluidized catalytic cracking slurry oil-in-water emulsion as anti-collapse agent for drilling fluids显示文摘Fluidized catalytic cracking slurry oil-in-water emulsion(FCCSE)was prepared by using interfacial complexes generation method that was simple and versatile.The critical factors influencing the sample preparation process were optimized,for instance,the optimum value of the mixed hydrophile-lipophile balance of compound emulsifier was 11.36,the content of compound emulsifier was 4 wt%,the emulsification temperature was 75C,the agitation speed was 200 rpm,and the emulsification time was 30e45 min.The performance as a drilling fluid additive was also investigated with respect to rheological properties,filtration loss and inhibition of FCCSE.Experimental results showed that FCCSE was favorable to inhibiting clay expansion and dispersion and reducing fluid loss.Furthermore,it had good compatibility with other additives and did not affect the rheological properties of drilling fluids.FCCSE exhibited better performance than the available emulsified asphalt.It has a promising application as anti-collapse agent in petroleum and natural gas drilling. | Zhengqiang Xiong Shixian Tao Xiaodong Li Fan Fu Yanning Li | 2016 | Petroleum2016，2，4： | 4 |
| 8 | Optimal Price-Based Power Control Algorithm with Quality of Service Constraints in Cognitive Radio Networks显示文摘In price-based cognitive radio networks,the Primary user(PU) can allow the Secondary users(SUs) to access by pricing if their interference power is under the Interference power constraint(IPC). The interaction between the PU and the SUs is modeled as a Stackelberg game with the consideration of the Quality of service(Qo S) of the SUs. The revenue maximization problem of PU is expressed as an equivalent convex optimization problem if the minimum Signal-to-interference and noise ratio(SINR) constraints for the SUs are greater than or equal to 0d B. An optimal pricing algorithm is proposed based on this equivalent convex optimization problem. Simulation results show that the proposed pricing algorithm outperforms the non-uniform pricing algorithm in terms of the revenue of the PU, the sum rate of SUs and the number of admitted SUs. | WANG Zhengqiang JIANG Lingge HE Chen | 2015 | Chinese Journal of Electronics2015，24，2： | 4 |
| 9 | Physicochemical Properties and Bioactivities of Rice Beans Fermented by Bacillus amyloliquefaciens显示文摘The purpose of this study was to investigate the physicochemical properties and bioactivities of rice beans(Vigna umbellata)fermented by Bacillus amyloliquefaciens.The fermentation conditions were optimized on the basis of the fibrinolytic activity.Under the optimal fermentation conditions,the fibrinolytic activity reached a maximum of 78.0 FU·g^(-1)(4890 IU·g^(-1),fibrin plate method,FU:fibrin degradation unit).The contents of peptides(which increased from 2.1 to 10.9 g per 100 g),total phenolics(from 116.7 to 388.5 mg gallic acid per 100 g),total flavonoids(from 235.5 to 354.3 mg rutin per 100 g),and anthocyanin(from 20.1 to 47.1 mg per 100 g),as well as the superoxide dismutase activity(from 55.3 to 263.6 U·g^(-1))in rice beans were significantly increased after fermentation.The 2,2-diphenyl-1-picrylhydrazyl(DPPH)and 2,2-azinobis(3-ethylbenzothiazoline-6-sulphonic acid)diammonium salt(ABTS)free radical scavenging activities and ferric reducing antioxidant power(FRAP)of fermented rice beans were 1.9–4.8 times higher than those of unfermented rice beans.Moreover,fermentation induced an increase in the dipeptidyl peptidase IV(DPP-IV)inhibition,a-glucosidase inhibition,and anticoagulant activities of rice beans.Rice beans fermented by Bacillus amyloliquefaciens may serve as a functional food with potential benefits for the prevention of thrombotic diseases. | Shan Wu Shuai Lu Jun Liu Shaoqing Yang Qiaojuan Yan Zhengqiang Jiang | 2021 | Engineering2021，7，2： | 3 |
| 10 | Dendrite-structured FeF_(2) consisting of closely linked nanoparticles as cathode for high-performance lithium-ion capacitors显示文摘Lithium-ion capacitors(LICs)are regarded as a good choice for next-generation energy storage devices,which are expected to exhibit high energy densities,high power densities,and ultra-long cycling stability.Nevertheless,only a few battery-type cathode materials with limited kinetic properties can be employed in LICs,and their electrochemical properties need to be optimized urgently.Here,we exploit a new dendrite-structured FeF_(2) consisting of closely linked primary nanoparticles using a facile solvothermal method combined with the subsequent annealing treatment.This particular architecture has favorable transport pathways for both lithium ions and electrons and exhibits an ultrafast chargedischarge capability with high reversible capacities.Furthermore,a well-designed LIC employing the prepared dendrite-structured FeF_(2) as the battery-type cathode and commercialized activated carbon(AC)as supercapacitor-type anode was constructed in an organic electrolyte containing Li ions.The LIC operates at an optimal voltage range of 1.1-3.8 V and shows a maximum high energy density of 152 W h kg^(-1) and a high power density of 4900 W kg^(-1) based on the total mass of cathode and anode.Long-term cycling stability(85%capacity retention after 2000 cycles)was achieved at 1 A g^(-1).This work suggests that the dendrite-structured FeF_(2) is a prime candidate for high-performance LICs and accelerates the development of hybrid ion capacitor devices. | Huanyu Liang Zhengqiang Hu Zhongchen Zhao Dong Chen Hao Zhang Huaizhi Wang Xia Wang Qiang Li Xiangxin Guo Hongsen Li | 2021 | Journal of Energy Chemistry2021，30，4： | 3 |
| 11 | Expression and responses to dehydration and salinity stresses of V-PPase gene members in wheat显示文摘Vacuolar H+-translocating pyrophosphatase(V-PPase) is a key enzyme related to plant growth as well as abiotic stress tolerance.In this work,wheat V-PPase genes TaVP1,TaVP2 and TaVP3 were identified.TaVP1 and TaVP2 are more similar to each other than to TaVP3.Their deduced polypeptide sequences preserve the topological structure and essential residues of V-PPases.Phylogenetic studies suggested that monocot plants,at least monocot grasses,have three VP paralogs.TaVP3 transcripts were only detected in developing seeds,and no TaVP2 transcripts were found in germinating seeds.TaVP2 was mainly expressed in shoot tissues and down-regulated in leaves under dehydration.Its expression was up-regulated in roots under high salinity.TaVP1 was relatively more ubiquitously and evenly expressed than TaVP2.Its expression level in roots was highest among the tissues examined,and was inducible by salinity stress.These results indicated that the V-PPase gene paralogs in wheat are differentially regulated spatially and in response to dehydration and salinity stresses. | Yuezhi Wang Haibin Xu Guangxiang Zhang Huilan Zhu Lixia Zhang Zhengzhi Zhang Caiqin Zhang Zhengqiang Ma | 2009 | Journal of Genetics and Genomics2009，36，12： | 3 |
| 12 | Vibration-dependent Crystal Form of Isotactic Polypropylene under Nonisothermal Crystallization显示文摘A study concerning the effect of vibration on the crystal structure and morphology for isotactic polypropylene(iPP) was conducted. The crystallite size, crystal structure and crystallinity of iPP under or without vibration treatment were investigated by means of differential scanning calorimetry(DSC) and wide-angle X-ray diffraction(WAXD). The results reveal that the crystallinity of the vibrated samples decreases at a high cooling rate, but it remains constant at a low cooling rate because of the chain relaxation of iPP. It has been found that vibration obviously increases the content of β-form of crystal phase and the amount of β-crystal mainly depends on the vibration amplitude. | SHANGGUANYong-gang TONGLi-fang PENGMao ZHENGQiang | 2004 | Chemical Research in Chinese Universities2004，20，5： | 2 |
| 13 | The mechanisms of melanogenesis inhibition by glabridin:molecular docking,PKA/MITF and MAPK/MITF pathways显示文摘Glabridin is the main ingredient of hydrophobic fraction in licorice extract and has been shown to have anti-melanogenesis activity in skins.However,the underlying mechanism(s)remain not completely understood.The aim of this study is thus to elucidate the possible mechanisms related to the melanogenesis suppression by glabridin in cultured B16 murine melanoma cells and in UVA radiation induced hyperpigmentation model of BALB/c mice as well.Molecular docking simulations revealed that between catalytic core residues and the compound.The treatment by glabridin significantly downregulated both transcriptional and/or protein expression of melanogenesis-related factors including melanocyte stimulating hormone receptor(MC1R),microphthalmia-associated transcription factor(MITF),tyrosinase(TYR),TYR-related protein-1(TRP-1)and TRP-2 in B16 cells.Both PKA/MITF and MAPK/MITF signaling pathways were found to be involved in the suppression of melanogenesis by glabridin in B16 cells.Also in vivo glabridin therapy significantly reduced hyperpigmentation,epidermal thickening,roughness and inflammation induced by frequent UVA exposure in mice skins,thus beneficial for skin healthcare.These data further look insights into the molecular mechanisms of melanogenesis suppression by glabridin,rationalizing the application of the natural compound for skin healthcare. | Chunxing Pan Xiaoying Liu Yating Zheng Zejun Zhang Yongliang Li Biao Che Guangrong Liu Lanyue Zhang Changzhi Dong Haji Akber Aisa Zhiyun Du Zhengqiang Yuan | 2023 | Food Science and Human Wellness2023，12，1： | 2 |

| 15 | Preparation of an environmentally friendly emulsion-type lubricant based on crude rice bran wax显示文摘In this study,crude rice bran wax oil-in-water emulsion(named CRBWE)was prepared by agent-in-water method.The critical factors influencing the sample preparation process were optimized.For instance,the optimum hydrophile-lipophile balance value of compound emulsifier was 12.33–13.40,the content of compound emulsifier was 10 wt%,the emulsification temperature was 70°C–80°C,the agitation speed was 200 rpm,and the emulsification time was 30–45 min.The performances as a lubricant of drilling fluid were also evaluated with respect to lubricity,rheology and filtration loss of CRBWE.The results showed that CRBWE had good lubricity and didn't affect the rheological properties of drilling fluid.For example,when it was added into bentonite dispersion at room temperature with the fraction of 1 wt%,the coefficient of friction of bentonite dispersion dramatically decreased to 0.077,and the coefficient of friction reduced rate was greater than 80%.Overall,these findings indicated that CRBWE would have promising applications as environmental friendly lubricant of drilling fluids to reduce torque and drag in petroleum and natural gas drilling. | Zhengqiang Xiong Fan Fu Xiaodong Li Yanning Li | 2019 | Petroleum2019，5，1： | 2 |

| 17 | Discrimination of brownheart of Korla pear using vibration frequency spectrum technique显示文摘The purpose of this work was to use a nondestructive method for detecting the brownheart of Korla pear to reduce the chance of infection among pears without brownheart.A mechanical impulse method based on vibration testing system was used to excite the fruits.The consistent acquisition signal indicated that the test is repeatable at the same positions of fruit equator(cheek).A remarkable frequency signal was excited at 9-12 N force by a rubber tipped hammer.The dominant frequency was identified at the maximum response magnitude to assess the internal defect,and the result was not influenced by the distances between the defect borders and the excitation points.The sharp increase of defect mass could significantly affect the dominant frequency.Relationship between the dominant response frequency(fd)and the defect mass percentage(ω)was characterized by an equation fd=410.649e-0.0833ω+261.947 with a good correlation coefficient(R2=0.925).A defect mass of 2.281%was determined as a discrimination threshold.Once the threshold exceeded 2.281%,the defective pear could be classified with a high accuracy rate of 96.7%.This finding would provide guidance for determining the optimal detecting time to the brownheart of Korla pears,according to the specific storage conditions when the vibration frequency spectrum method is deployed. | Xu Hubo Wu Jie Wang Zhaopeng Gao Yongmao Wang Zhipeng Zhao Zhengqiang | 2017 | International Journal of Agricultural and Biological Engineering2017，10，2： | 1 |

| 20 | A Peridynamic Model for Analyzing Fracture Behavior of Functionally Graded Materials Used as an Interlayer显示文摘Functionally graded materials(FGMs)can be used els an interlayer.The interlayer connects two homogeneous materials and slows mutations in material properties,owing to the variability of parameters and microstructure.In this numerical simulation,a bond-based peridynamic(PD)model was used to perform dynamic fracture analysis of a continuous beam and a sandwiched structure with an FGM interlayer.Some simulation results of two convergence studies,which include grid refinement(m-convergence)and the reducing radius of PD horizon(^-convergence),were discussed.Under a four-point bending load,the propagation behaviors of single pre-crack in the continuous beam with the FGM interlayer at different locations are simulated to compare with the experimental results.For the sandwiched structure,the problems of a single crack and double cracks were considered.The numerical results show that the crack can deflect toward areas where the energy release rate is low.Additionally,the crack on the weak side for symmetric cracks only has fracture behavior,and if the double cracks are asymmetrical,all these cracks have fracture behaviors and propagation of the initial crack in the stiff region has a higher sensitivity than in the compliant region. | Zhanqi Cheng Zhengqiang Fu Yu Zhang Hongxia Wu | 2020 | Acta Mechanica Solida Sinica2020，33，6： | 1 |
