| 1 | Engineering Broad-Spectrum Bacterial Blight Resistance by Simultaneously Disrupting Variable TALE-Binding Elements of Multiple Susceptibility Genes in Rice显示文摘Xanthomonas oryzae pv.oryzae(Xoo),the causal agent of bacterial blight of rice,employs the transcription activator-like effectors(TALEs)to induce the expression of the OsSWEET family of putative sugar transporter genes,which function in conferring disease susceptibility(S)in rice plants.To engineer broadspectrum bacterial blight resistance,we used CRISPR/Cas9-mediated gene editing to disrupt the TALEbinding elements(EBEs)of two S genes,OsSWEETH and OsSWEET14,in rice cv.Kitaake,which harbors the recessive resistance allele of Xa25/OsSWEET13.The engineered rice line MS14K exhibited broadspectrum resistance to most Xoo strains with a few exceptions,suggesting that the compatible strains may contain new TALEs.We identified two PthXo2-like TALEs,Tal5LN18 and Tal7PX061,as major virulence factors in the compatible Xoo strains LN18 and PX061,respectively,and found that Xoo encodes at least five types of PthXo2-like effectors.Given that PthXo2/PthXo2.1 target OsSlVEETf3 for transcriptional activation,the genomes of 3000 rice varieties were analyzed for EBE variationsin the OsSWEET13 promoter,and 10Xa25-like haplotypes were identified.We found that Tal5LN18 and Tal7PX〇6i bind slightly different EBE sequences in the OsSWEET13 promoter to activate its expression.CRISPR/Cas9 technology was then used to generate InDels in the EBE of the OsSWEET13 promoter in MS14K to creat a new germplasm with three edited OsSWEET EBEs and broad-spectrum resistance against all Xoo strains tested.Collectively,our findings illustrate how to disarm TALE-S co-evolved loci to generate broad-spectrum resistance through the loss of effector-triggered susceptibility in plants. | Zhengyin Xu Xiameng Xu Qiang Gong Ziyang Li Ying Li Sai Wang Yangyang Yang Wenxiu Ma Longyu Liu Bo Zhu Lifang Zou Gongyou Chen | 2019 | Molecular Plant2019,12,11: | 29 |

| 3 | A genome-wide analysis of SWEET gene family in cotton and their expressions under different stresses显示文摘Background: The SWEET(Sugars will eventually be exported transporters) gene family plays multiple roles in plant physiological activities and development process. It participates in reproductive development and in the process of sugar transport and absorption, plant senescence and stress responses and plant-pathogen interaction. However,thecomprehensive analysis of SWEET genes has not been reported in cotton.Results: In this study, we identified 22, 31, 55 and 60 SWEET genes from the sequenced genomes of Gossypium arboreum, G. raimondii, G. hirsutum and G. barbadense, respectively. Phylogenetic tree analysis showed that the SWEET genes could be divided into four groups, which were further classified into 14 sub-clades. Further analysis of chromosomal location, synteny analysis and gene duplication suggested that the orthologs showed a good collinearity and segmental duplication events played a crucial role in the expansion of the family in cotton. Specific MtN3_slv domains were highly conserved between Arobidopsis and cotton by exon-intron organization and motif analysis. In addition, the expression pattern in different tissues indicated that the duplicated genes in cotton might have acquired new functions as a result of sub-functionalization or neo-funtionalization. The expression pattern of SWEET genes showed that the different genes were induced by diverse stresses. The identification and functional analysis of SWEET genes in cotton may provide more candidate genes for genetic modification.Conclusion: SWEET genes were classified into four clades in cotton. The expression patterns suggested that the duplicated genes might have experienced a functional divergence. This work provides insights into the evolution of SWEET genes and more candidates for specific genetic modification, which will be useful in future research. | ZHAO Lanjie YAO Jinbo CHEN Wei LI Yan L Youjun GUO Yan WANG Junyi YUAN Li LIU Ziyang ZHANG Yongshan | 2018 | Journal of Cotton Research2018,1,2: | 6 |
| 4 | Mechanical Properties of C_f/Mg Composites Fabricated by Pressure Infiltration Method显示文摘The carbon fibers and the woven reinforced magnesium matrix composites were fabricated by pressure infiltration method.Effects of fiber species,fiber arrangement,hybrid particles and environment temperature on microstructures and properties of the composite were studied.Results showed that the mechanical properties at ambient temperature were affected by interfacial reaction.The magnesium matrix composites reinforced with graphite fibers showed higher strength and elastic modulus due to less interfacial reaction.During loading,the fibers were pulled out and the load was transferred through the interfaces,then the fiber bundles were fractured,finally the whole specimen failed.The introduction of hybrid SiC particles during fabrication can improve the mechanical properties of the magnesium matrix composites.Moreover,taking orthogonal carbon fiber woven as reinforcement can modify the anisotropy and reliability of materials. | Meihui Songt Gaohui Wu Wenshu Yang Wei Jia Ziyang Xiu Guoqin Chen | 2010 | Journal of Materials Science & Technology2010,26,10: | 6 |
| 5 | Trithiocyanuric acid derived g-C3N4 for anchoring the polysulfide in Li-S batteries application显示文摘Lithium-sulfur (Li-S) batteries have great potential as an electrochemical energy storage system because of the high theoretical energy density and acceptable cost of financial and environment.However,the shuttle effect leads to severe capacity fading and low coulombic efficiency.Here,graphitic carbon nitride(g-C3N4) is designed and prepared via a feasible and simple method from trithiocyanuric acid (TTCA) to anchor the polysulfides and suppress the shuttle effect.The obtained g-C3N4 exhibits strong chemical interaction with polysulfides due to its high N-doping of 56.87 at%,which is beneficial to improve the cycling stability of Li-S batteries.Moreover,the novel porous framework and high specific surface area of g-C3N4 also provide fast ion transport and broad reaction interface of sulfur cathode,facilitating high capacity output and superior rate performance of Li-S batteries.As a result,Li-S batteries assembled with g-C3N4 can achieve high discharge capacity of 1200 mAh/g at 0.2 C and over 800 mAh/g is remained after 100 cycles with a coulombic efficiency more than 99.5%.When the C-rate rises to 5 C,the reversible capacity of Li-S batteries can still maintain at 607mAh/g. | Ziyang Jia Hongzhang Zhang Ying Yu Yuqing Chen Jingwang Yan Xianfeng Li Huamin Zhang | 2020 | Journal of Energy Chemistry2020,29,4: | 4 |
| 6 | Hierarchically porous carbon derived from natural Porphyra for excellent electromagnetic wave absorption显示文摘A highly efficient absorber with features including lightweight, broad bandwidth, and tunable electromagnetic property still remains challenging for practical applications. Herein, the Porphyra-derived porous carbon(PPC) was fabricated via facile procedures of low-temperature pre-carbonization combined with KOH chemical activation. The composition, microstructure, and electromagnetic wave absorption properties of the samples were elucidated based on X-ray diffraction(XRD), Raman, X-ray photoelectron spectroscopy(XPS), scanning electron microscopy(SEM), transmission electron microscopy(TEM),Brunauer-Emmer-Teller(BET), and vector network analyzer(VNA). The porosity of PPC can be readily regulated by adjusting activation temperature. The PPC obtained at 750 ℃ was composed of a threedimensional hierarchically porous carbon network. The C and N elements of natural Porphyra were introduced into the carbon skeleton during the carbonization process. The large specific surface, dopants, and three-dimensional hierarchically porous carbon network can effectively improve the impedance matching and dielectric dissipation, leading to an excellent electromagnetic wave absorption performance. Especially, the optimal reflection loss(RL) value reached –57.75 d B at 9.68 GHz with a broad bandwidth(RL< –10 d B) value of 7.60 GHz at 3.5 mm. Overall, the results indicate that the PPC can provide a new way to achieve lightweight, effective, and sustainable absorbers. | Juhua Luo Ziyang Dai Mengna Feng Xiaowen Chen Caihong Sun Ying Xu | 2022 | Journal of Materials Science & Technology2022,,34: | 4 |
| 7 | Effect of a second metal(Co,Fe, Mo and W) on performance of Ni_2P/SiO_2 for hydrodeoxygenation of methyl laurate显示文摘Ni_2P/SiO_2 and bimetallic Ni MP/Si O2(M = Co, Fe, Mo, W; Ni/M atomic ratio=5) catalysts were prepared by the temperature-programmed reduction method. The catalysts and their precursors were characterized by means of UV–Vis DRS, H_2-TPR, XRD, TEM, CO chemisorption and NH_3-TPD. Their performance for the deoxygenation of methyl laurate was tested on a fixed-bed reactor. The results show that the main phase was Ni_2 P in all catalysts, and M(M = Co, Fe, Mo, W) entered the lattice of Ni_2 P forming solid solution. Different from Fe and Co, the introduction of Mo and W into Ni_2P/SiO_2 reduced the phosphide particle size and increased the acid amount. In the deoxygenation reaction, the turnover frequency of methyl laurate increased on the catalysts in the order of NiMoP/SiO_2, Ni_2P/SiO_2, Ni WP/Si O2, NiFeP/SiO_2 and NiCoP/SiO_2, which is influenced by the size of phosphide particles and the interaction between Ni and M(M = Fe, Co, Mo or W). The introduction of the second metal(especially Mo and W) into Ni_2P/SiO_2 promoted the hydrodeoxygenation pathway. This is mainly attributed to the interaction between Ni and the second metal. Finally, the Ni MoP/SiO_2 catalyst was tested at 340 oC, 3 MPa, methyl laurate WHSV of 14 h-1and H_2/methyl laurate molar ratio of 25 for 132 h, and its deactivation took place. We found that the catalyst deactivation mainly resulted from carbonaceous deposit rather than the sintering of metal phosphide crystallites. | Zhengyi Pan Rijie Wang Ziyang Nie Jixiang Chen | 2016 | Journal of Energy Chemistry2016,25,3: | 3 |

| 10 | Coherence-enhancing line drawing for color images显示文摘Line drawing plays an important role in many image-based non-photorealistic applications.However,most existing approaches use a grayscale edge detector for line extraction,so that only luminance diferences between nearby image pixels is taken into account,but the chrominance diferences is ignored.This leads to the undesirable consequence that visually signifcant edges in adjacent regions with diferent colors of similar luminance cannot be detected.To address this limitation,we present a novel enhanced line drawing method based on a flow-based diference-of-Gaussians(FDoG)flter.Because of an inherent property of the thresholded DoG edge model,captured lines may appear dislodged from the true edges in the image.To this end,we provide a gradient-guided warping technique so that smooth and coherent lines can be extracted in the correct location.The GPU implementation of the proposed algorithms allows real-time performance,and experimental examples with various color images demonstrate the method’s superior qualitative performance over previous approaches. | WANG ShanDong MA ZiYang LIU XueHui CHEN YanYun WU EnHua | 2013 | Science China(Information Sciences)2013,56,11: | 2 |
| 11 | An MPC-based manoeuvre stability controller for full drive-by-wire vehicles显示文摘Aiming at the actuator time delay caused by the drive-by-wire technology,a novel manoeuvre stability controller based on model predictive control is proposed for full drive-by-wire vehicles.Firstly,the future vehicle dynamics are predicted by a twodegree-of-freedom vehicle model with input delay.Secondly,in order to prevent the vehicle from destabilizing due to excessive side slip angles,the determined ideal yaw rate and side slip angle are tracked simultaneously by optimizing the front wheel angle and additional yaw moment.Moreover,in order to improve the trajectory tracking ability,a side slip angle constraint determined by phase plane stability boundaries is added to the cost function.The results of Matlab and veDYNA co-simulation show that the regulated yaw rate can track the reference value well and the side slip angle decreases.Meanwhile,the trajectory tracking ability is improved obviously by compensating the time delay. | Ping WANG Ziyang LIU Qifang LIU Hong CHEN | 2019 | Control Theory and Technology2019,17,4: | 2 |
| 12 | Rate compatible reconciliation for continuous-variable quantum key distribution using Raptor-like LDPC codes显示文摘In the practical continuous-variable quantum key distribution(CV-QKD)system,the postprocessing process,particularly the error correction part,significantly impacts the system performance.Multi-edge type low-density parity-check(MET-LDPC)codes are suitable for CV-QKD systems because of their Shannon-limit-approaching performance at a low signal-to-noise ratio(SNR).However,the process of designing a low-rate MET-LDPC code with good performance is extremely complicated.Thus,we introduce Raptor-like LDPC(RL-LDPC)codes into the CV-QKD system,exhibiting both the rate compatible property of the Raptor code and capacity-approaching performance of MET-LDPC codes.Moreover,this technique can significantly reduce the cost of constructing a new matrix.We design the RL-LDPC matrix with a code rate of 0.02 and easily and effectively adjust this rate from 0.016 to 0.034.Simulation results show that we can achieve more than 98%reconciliation efficiency in a range of code rate variation using only one RL-LDPC code that can support high-speed decoding with an SNR less than-16.45 d B.This code allows the system to maintain a high key extraction rate under various SNRs,paving the way for practical applications of CV-QKD systems with different transmission distances. | Chao Zhou Xiang Yu Wang ZhiGuo Zhang Song Yu ZiYang Chen Hong Guo | 2021 | Science China(Physics,Mechanics & Astronomy)2021,64,6: | 2 |
| 13 | Extremely large-amplitude oscillation of soft pipes conveying fluid under gravity显示文摘In this work,the nonlinear behaviors of soft cantilevered pipes containing internal fluid flow are studied based on a geometrically exact model,with particular focus on the mechanism of large-amplitude oscillations of the pipe under gravity.Four key parameters,including the flow velocity,the mass ratio,the gravity parameter,and the inclination angle between the pipe length and the gravity direction,are considered to affect the static and dynamic behaviors of the soft pipe.The stability analyses show that,provided that the inclination angle is not equal to π,the soft pipe is stable at a low flow velocity and becomes unstable via flutter once the flow velocity is beyond a critical value.As the inclination angle is equal to π,the pipe experiences,in turn,buckling instability,regaining stability,and flutter instability with the increase in the flow velocity.Interestingly,the stability of the pipe can be either enhanced or weakened by varying the gravity parameter,mainly dependent on the value of the inclination angle.In the nonlinear dynamic analysis,it is demonstrated that the post-flutter amplitude of the soft pipe can be extremely large in the form of limit-cycle oscillations.Besides,the oscillating shapes for various inclination angles are provided to display interesting dynamical behaviors of the inclined soft pipe conveying fluid. | Wei CHEN Ziyang HU Huliang DAI Lin WANG | 2020 | Applied Mathematics and Mechanics(English Edition)2020,41,9: | 2 |
| 14 | Electroporation-Mediated Immunization of a Candidate DNA Vaccine Expressing Dengue Virus Serotype 4 prM-E Antigen Confers Long-Term Protection in Mice显示文摘Dengue fever, caused by dengue viruses(DENVs), is a widespread mosquito-borne zoonotic disease; however, there is no available anti-dengue vaccine for worldwide use. In the current study, a DNA vaccine candidate(pV-D4 ME) expressing prM-E protein of DENV serotype 4(DENV-4) was constructed, and its immunogenicity and protection were evaluated in immunocompetent BALB/c mice. The pV-D4 ME candidate vaccine induced effective humoral and cellular immunity of mice against DENV-4 in vivo when administered both at 50 μg and 5 μg through electroporation. Two weeks after receiving three immunizations, both doses of pV-D4 ME DNA were shown to confer effective protection against lethal DENV-4 challenge. Notably, at 6 months after the three immunizations, 50 μg, but not 5 μg, of pV-D4 ME could provide stable protection(100% survival rate) against DENV-4 lethal challenge without any obvious clinical signs. These results suggest that immunization with 50 μg pV-D4 ME through electroporation could confer effective and long-term protection against DENV-4, offering a promising approach for development of a novel DNA vaccine against DENVs. | Ziyang Sheng Hui Chen Kaihao Feng Na Gao Ran Wang Peigang Wang Dongying Fan Jing An | 2019 | Virologica Sinica2019,34,1: | 2 |
| 15 | Electrochemical Proton Storage:From Fundamental Understanding to Materials to Devices显示文摘Simultaneously improving the energy density and power density of electrochemical energy storage systems is the ultimate goal of electrochemical energy storage technology.An effective strategy to achieve this goal is to take advantage of the high capacity and rapid kinetics of electrochemical proton storage to break through the power limit of batteries and the energy limit of capacitors.This article aims to review the research progress on the physicochemical properties,electrochemical performance,and reaction mechanisms of electrode materials for electrochemical proton storage.According to the different charge storage mechanisms,the surface redox,intercalation,and conversion materials are classified and introduced in detail,where the influence of crystal water and other nanostructures on the migration kinetics of protons is clarified.Several reported advanced full cell devices are summarized to promote the commercialization of electrochemical proton storage.Finally,this review provides a framework for research directions of charge storage mechanism,basic principles of material structure design,construction strategies of full cell device,and goals of practical application for electrochemical proton storage. | Tiezhu Xu Di Wang Zhiwei Li Ziyang Chen Jinhui Zhang Tingsong Hu Xiaogang Zhang Laifa Shen | 2022 | Nano-Micro Letters2022,14,8: | 1 |
| 16 | Quantum cascade superluminescent light emitters with high power and compact structure显示文摘Quantum cascade(QC)superluminescent light emitters(SLEs)have emerged as desirable broadband mid-infrared(MIR)light sources for growing number of applications in areas like medical imaging,gas sensing and national defense.However,it is challenging to obtain a practical high-power device due to the very low efficiency of spontaneous emission in the intersubband transitions in QC structures.Herein a design of^5μm SLEs is demonstrated with a two-phonon resonancebased QC active structure coupled with a compact combinatorial waveguide structure which comprises a short straight part adjacent to a tilted stripe and to a J-shaped waveguide.The as-fabricated SLEs achieve a high output power of 1.8 mW,exhibiting the potential to be integrated into array devices without taking up too much chip space.These results may facilitate the realization of SLE arrays to attain larger output power and pave the pathway towards the practical applications of broadband MIR light sources. | Jialin Sun Chuncai Hou Hongmei Chen Jinchuan Zhang Ning Zhuo Jiqiang Ning Changcheng Zheng Zhanguo Wang Fengqi Liu Ziyang Zhang | 2020 | Journal of Semiconductors2020,41,1: | 1 |
