| 1 | A 2-kb Mycovirus Converts a Pathogenic Fungus into a Beneficial Endophyte for Brassica Protection and Yield Enhancement显示文摘Mycoviruses are viruses that infect fungi,and hypovirulence-associated mycoviruses have the potential to control fungal diseases.However,it is unclear how mycovirus-mediated hypovirulent strains live and survive in the field,and no mycovirus has been applied for field crop protection.In this study,we found that a previously identified small DNA mycovirus(SsHADV-1)can convert its host,Sclerotinia sclerotiorum,from a typical necrotrophic pathogen to a beneficial endophytic fungus.SsHADV-1 downregulates the expression of key pathogenicity factor genes in S.sclerotiorum during infection.When growing in rapeseed,the SsHADV-1-infected strain DT-8 significantly regulates the expression of rapeseed genes involved in defense,hormone signaling,and circadian rhythm pathways.As a result,plant growth is promoted and disease resistance is enhanced.Field experiments showed that spraying DT-8 at the early flowering stage can reduce the disease severity of rapeseed stem rot by 67.6%and improve yield by 14.9%.Moreover,we discovered that SsHADV-1 could also infect other S.sclerotiorum strains on DT-8-inoculated plants and that DT-8 could be recovered from dead plants.These findings suggest that the mycoviruses may have the ability to shape the origin of endophytism.Our discoveries suggest that mycoviruses may influence the origin of endophytism and may also offer a novel strategy for disease control in which mycovirus-infected strains are used to improve crop health and release mycoviruses into the field. | Hongxiang Zhang Jiatao Xie Yanping Fu Jiasen Cheng Zheng Qu Zhenzhen Zhao Shufen Cheng Tao Chen Bo Li Qianqian Wang Xinqiang Liu Binnian Tian David B.Collinge Daohong Jiang | 2020 | Molecular Plant2020,13,10: | 9 |
| 2 | Enhanced dewaterability of waste activated sludge by UV assisted ZVI-PDS oxidation显示文摘Ultraviolet(UV)assisted zero-valent iron(ZVI)-activated sodium persulfate(PDS)oxidation(UV-ZVI-PDS)was used to treat waste activated sludge(WAS)in this study.The dewaterability performance and mechanism of WAS dewatering were analyzed.The results showed that UV-ZVI-PDS can obtain better sludge dewatering performance in a wide pH range(2.0-8.0).When the molar ratio of ZVI/PDS was 0.6,UV was 254nm,PDS dosage was 200 mg/g TS(total solid),pH was 6.54,reaction time was 20 min,the CST(capillary suction time)and SRF(specific resistance to filtration)were decreased by 64.0%and 78.2%,respectively.The molar ratio of ZVI/PDS used in this paper is much lower than that of literatures,and the contents of total Fe and Fe^(2+) in sludge supernatant remained at a low level,as 3.7 mg/L and 0.0 mg/L.The analysis of extracellular polymeric substances(EPS),scanning electron microscope(SEM)and particle size distribution showed that the EPS could be effectively destroyed by UV-ZVI-PDS,the sludge flocs broken down into smaller particles,cracks and holes appeared,and then the bound water was released.At the same time,the highly hydrophilic tightly bound-EPS(TB-EPS)were converted into loosely bound EPS(LB-EPS)and soluble EPS(S-EPS).During sludge pretreated by UV-ZVI-PDS,positively charged ions,such as Fe^(2+),Fe^(3+) and H^(+),produced in the reaction system could reduce the electronegativity of sludge surface,promote sludge particles aggregation,and then enhanced the sludge dewaterability. | Yanping Zhang Tiantian Li Jiayu Tian Huichun Zhang Fen Li Jiahua Pei | 2022 | Journal of Environmental Sciences2022,34,3: | 7 |
| 3 | Effects of Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) medicated serum on chemotactic migration of alveolar macrophages and inters regions macrophages in rats显示文摘OBJECTIVE: To observe the effects of serum containing Mahuang(Herba Ephedra Sinica) or Wuweizi(Fructus Schisandrae Chinensis) on the migration of alveolar macrophages(AM) and interstitial macrophages(IM) from normal rats, and to analyze and compare the mechanisms leading to cell migration differences.METHODS: Rats were randomly divided into three groups: Mahuang(Herba Ephedra Sinica), Wuweizi(Fructus Schisandrae Chinensis), and blank serum. After treatment with the herbs, serum was extracted from the rats. AM and IM were isolated from normal rats and cultured. The effects of Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) medicated serum on normal rat AM and IM chemotactic migration were determined by transwell assays. The CC chemokine receptor(CCR) 2, CCR5, voltage-gated Kvl. 3 K^+channel(Kv1. 3), and voltage-gated Kvl. 5 K^+channel(Kv1. 5) protein levels were analyzed by western blotting.RESULTS: The migration quantities of AM and IM in the Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) medicated serum groups were significantly higher than those in the blank serum group(P < 0.01). Compared with the Wuweizi(Fructus Schisandrae Chinensis) medicated serum group, the migration quantity of cultured rat AM in the Mahuang(Herba Ephedra Sinica) medicated serum group was significantly increased(P <0.01). Meanwhile, compared with the Mahuang(Herba Ephedra Sinica) medicated serum group, the migration quantity of cultured rat IM in the Wuweizi(Fructus Schisandrae Chinensis) medicated serum group was significantly increased(P < 0.01).CCR2, CCR5, Kv1. 3, and Kv1. 5 proteins were expressed on the AM cell surface, and showed significantly higher expression in the Mahuang(Herba Ephedra Sinica) medicated serum group compared with the Wuweizi(Fructus Schisandrae Chinensis)medicated serum group. In contrast, CCR5, Kv1.3,and Kv1.5 proteins were expressed on the IM cell surface, and showed significantly higher expression in the Wuweizi(Fructus Schisandrae Chinensis)medicated serum group compared with the Mahuang(Herba Ephedra Sinica) medicated serum group.CONCLUSION: Mahuang(Herba Ephedra Sinica)and Wuweizi(Fructus Schisandrae Chinensis) can promote AM and IM migration ability, with Mahuang(Herba Ephedra Sinica) targeting AM more apparently and Wuweizi(Fructus Schisandrae Chinensis) targeting IM more apparently. The mechanism may be that, by stimulating cells, Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) promote expression of CCR2 and CCR5 receptors on the AM and IM cell surface,which pass signals to Kvl.3 and Kvl.5 ion channels,leading to changes in the cytoskeleton, and ultimately promoting chemotactic cell migration. | Yuan Yiping Zhai Huaqiang Zhang Tian Guo Zhaojuan Kong Liting Jia Xiaoyu Wang Ningning Dai Ying Liu Guoxiu Wang Yanping | 2017 | Journal of Traditional Chinese Medicine2017,37,5: | 3 |
| 4 | Structural basis of ALMT1-mediated aluminum resistance in Arabidopsis显示文摘The plant aluminum(Al)-activated malate transporter ALMT1 mediates the efflux of malate to chelate the Al in acidic soils and underlies the plant Al resistance.Here we present cryo-electron microscopy(cryo-EM)structures of Arabidopsis thaliana ALMT1(AtALMT1)in the apo,malate-bound,and Al-bound states at neutral and/or acidic pH at up to 3.0Åresolution.The AtALMT1 dimer assembles an anion channel and each subunit contains six transmembrane helices(TMs)and six cytosolicα-helices.Two pairs of Arg residues are located in the center of the channel pore and contribute to malate recognition.Al binds at the extracellular side of AtALMT1 and induces conformational changes of the TM1-2 loop and the TM5-6 loop,resulting in the opening of the extracellular gate.These structures,along with electrophysiological measurements,molecular dynamic simulations,and mutagenesis study in Arabidopsis,elucidate the structural basis for Al-activated malate transport by ALMT1. | Jiangqin Wang Xiafei Yu Zhong Jie Ding Xiaokang Zhang Yanping Luo Ximing Xu Yuan Xie Xiaoxiao Li Tian Yuan Shao Jian Zheng Wei Yang Jiangtao Guo | 2022 | Cell Research2022,32,1: | 3 |

| 7 | High-temperature superconductivity in sulfur hydride evidenced by alternating-current magnetic susceptibility显示文摘The search for high-temperature superconductivity is one of the research frontiers in physics. In the sulfur hydride system, an extremely high T_c(~200 K) has been recently developed at pressure. However, the Meissner effect measurement above megabar pressures is still a great challenge. Here, we report the superconductivity identification of sulfur hydride at pressure, employing an in situ alternating-current magnetic susceptibility technique. We determine the superconducting phase diagram, finding that superconductivity suddenly appears at 117 GPa and Tcreaches 183 K at 149 GPa before decreasing monotonically with increasing pressure. By means of theoretical calculations, we elucidate the variation of T_c in the low-pressure region in terms of the changing stoichiometry of sulfur hydride and the further decrease in Tcowing to a drop in the electron–phonon interaction parameter λ. This work provides a new insight into clarifying superconducting phenomena and anchoring the superconducting phase diagram in the hydrides. | Xiaoli Huang Xin Wang Defang Duan Bertil Sundqvist Xin Li Yanping Huang Hongyu Yu Fangfei Li Qiang Zhou Bingbing Liu Tian Cui | 2019 | National Science Review2019,6,4: | 2 |
| 8 | Effects of confined longitudinal and interface optical phonons on excitons in an asymmetric quantum well显示文摘The interaction between exciton and confined longitudinal optical (LO) phonons, interface optical (IO) phonons in an asymmetric Ga 1 x Al x As/GaAs/Ga 0.7 Al 0.3 As square quantum well is investigated. By applying the LLP-like transformation and variational approach, the numerical results are obtained as functions of the well width and asymmetric-degree of well. The exciton-optical phonons interaction-energy has a minimum value with the increase of the well width. It is demonstrated that the LO-phonon energy-contribution increases while the IO-phonon contribution decreases as the well width increases gradually The energy-contribution of LO-phonon in symmetric and asymmetric square quantum well does not have too much difference but the IO-phonon contribution varies apparently. The exciton binding-energy monotonically decreases with the increase of the well width and is proportional to the left-barrier height. | DENG YanPing TIAN Qiang | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,9: | 2 |
| 9 | Transcriptomic Response to Yersinia pestis:RIG-I Like Receptor Signaling Response Is Detrimental to the Host against Plague显示文摘Bacterial pathogens have evolved various mechanisms to modulate host immune responses for successful infection.In this study,RNAsequencing technology was used to analyze the responses of human monocytes THP1 to Yersinia pestis infection.Over 6000 genes were differentially expressed over the 12 h infection.Kinetic responses of pathogen recognition receptor signaling pathways,apoptosis,antigen processing,and presentation pathway and coagulation system were analyzed in detail.Among them,RIG-I-like receptor(RLR) signaling pathway,which was established for antiviral defense,was significantly affected.Mice lacking MAVS,the adaptor of the RLR signahng pathway,were less sensitive to infection and exhibited lower IFN-P production,higher Thl-type cytokines IFN-y and IL-12 production,and lower Th2-type cytokines EL-4 and IL-13 production in the serum compared with wild-type mice.Moreover,infection of pathogenic bacteria other than Y.pestis also altered the expression of the RLR pathway,suggesting that the response of RLR pathway to bacterial infection is a universal mechanism. | Zongmin Du Huiying Yang Yafang Tan Guang Tian Qingwen Zhang Yujun Cui Yanfeng Yan Xiaohong Wu Zuyun Chen Shiyang Cao Yujing Bi Yanping Han Xiaoyi Wang Yajun Song Ruifu Yan | 2014 | Journal of Genetics and Genomics2014,41,7: | 2 |
| 10 | Hyperactive PI3Kδ predisposes naive T cells to activation via aerobic glycolysis programs显示文摘Activated phosphoinositide 3-kinaseδsyndrome(APDS)is an autosomal-dominant combined immunodeficiency disorder resulting from pathogenic gain-of-function(GOF)mutations in the PIK3CD gene.Patients with APDS display abnormal T cell homeostasis.However,the mechanisms by which PIK3CD GOF contributes to this feature remain unknown.Here,with a cohort of children with PIK3CD GOF mutations from multiple regions of China and a corresponding CRISPR/Cas9 gene-edited mouse model,we reported that hyperactive PI3Kδdisrupted TNaive cell homeostasis in the periphery by intrinsically promoting the growth,proliferation,and activation of TNaive cells.Our results showed that PIK3CD GOF resulted in loss of the quiescence-associated gene expression profile in naive T cells and promoted naive T cells to overgrow,hyperproliferate and acquire an activated functional status.Naive PIK3CD GOF T cells exhibited an enhanced glycolytic capacity and reduced mitochondrial respiration in the resting or activated state.Blocking glycolysis abrogated the abnormal splenic T cell pool and reversed the overactivated phenotype induced by PIK3CD GOF in vivo and in vitro.These results suggest that enhanced aerobic glycolysis is required for PIK3CD GOF-induced overactivation of naive T cells and provide a potential therapeutic approach for targeting glycolysis to treat patients with APDS as well as other immune disorders. | Yanjun Jia Qiuyun Yang Yanping Wang Wenyan Li Xuemei Chen Tao Xu Zhirui Tian Minxuan Feng Liang Zhang Wenjing Tang Na Tian Lina Zhou Wenxia Song Xiaodong Zhao | 2021 | Cellular & Molecular Immunology2021,18,7: | 2 |
| 11 | BUCKLING AND POSTBUCKLING ANALYSIS OF ELASTO-PLASTIC FIBER METAL LAMINATES显示文摘The elasto-plastic buckling and postbuckling of fiber metal laminates(FML) are studied in this research. Considering the geometric nonlinearity of the structure and the elastoplastic deformation of the metal layers, the incremental Von Karman geometric relation of the FML with initial deflection is established. Moreover, an incremental elasto-plastic constitutive relation adopting the mixed hardening rule is introduced to depict the stress-strain relationship of the metal layers. Subsequently, the incremental nonlinear governing equations of the FML subjected to in-plane compressive loads are derived, and the whole problem is solved by the iterative method according to the finite difference method. In numerical examples, the effects of the initial deflection,the loading state, and the geometric parameters on the elasto-plastic buckling and postbuckling of FML are investigated, respectively. | Rengui Bi Yiming Fu Yanping Tian Chao Jiang | 2014 | Acta Mechanica Solida Sinica2014,27,1: | 2 |
| 12 | Single-phase Computational Fluid Dynamics Applicability for the Study of Three-dimensional Flow in 5×5 Rod Bundles with Spacer Grids显示文摘Spacer grids play an important role in pressurized water reactor(PWR) fuel assembly in that they have significant influence on the thermal-hydraulic characteristics of the reactor core.But so far,the numerical studies are performed without regarding dimple and spring of spacer grids,just considering mixing vane.Moreover,these studies use k-ε turbulence model without considering the suitability of the other turbulence models upon the different spacer grids flow.A study is carried out to understand the 3-D single-phase flow in AFA-2G 5×5 rod bundles with spacer grids based on numerical method.In order to investigate the suitability of different turbulence models,k-ε model and k-ω model,the influence of different parts of spacer grid on the fluid flow is also predicted.By using second-order upwind scheme,hybrid grids technique,and improved SIMPLEC algorithm,the Reynolds averaged mass conservation and momentum conservation equations are solved,and the pressure and velocity field of flow are obtained.The numerical simulation results are compared with experiment results and the agreement is satisfactory.The simulation results show the influences of the spring,dimple and mixing vane,and the different characteristics of the k-ε model and k-ω model.Comparing with the experiment results,the simulation results suggest that the k-ω model is suitable for the simulation of the rod bundle flow with spacer grids;the spring and dimple are the main causes of the pressure loss in the spacer grid channel.The friction coefficient of the channel with spring and dimple is 1.5 times the coefficient of the channel with the vane.These results are beneficial to enhance the simulation ability of spacer grids flow and optimization design ability of spaces grid. | TIAN Ruifeng MAO Xiaohui GAO Puzhen HUANG Yanping | 2012 | Chinese Journal of Mechanical Engineering2012,25,4: | 1 |

| 14 | How Do China's Importing Firms Respond to Non-taritf Measures?显示文摘After the formation of the World Trade Organization(WTO)in 1995,most countries gradually reduced their import tariffs to a fairly low level.However,the reduced tariffs could not he simply read as a reduction in trade barriers.Indeed,many suspect that countries tend to use more non-tariff measures(NTMs),substituting them for tariff barriers,to protect their domestic economies.This paper uses newly compiled and detailed Chinese NTM data,together with highly disaggregated firm import data and manufacturing firm operational data,to investigate the impact of China s import-related NTMs on firm imports.The main empirical results show that,as in the case of tariff barriers,China s trade policy NTMs mainly inhibit firms'intermediate imports.In contrast,China s public policy NTMs significantly improve the intensive and extensive margins of firm s intermediate imports and raise the prices and quality of imported inputs.The greater the extent to which a firm engages in processing trade,the larger is the promoting effect of public policy NTMs on the firm s import margins far intermediate inputs,and the greater is the restricting ejfect on the prices and the quality of the firm's imported inputs. | Xiaodan Hu Yunhua Tian Yanping Zhou Lu Feng | 2021 | China & World Economy2021,29,4: | 1 |

| 17 | Effects of different root zone heating systems on the microclimate and crop development in solar greenhouses显示文摘Heating greenhouse is indispensable for plant development particularly in winter when the air temperature is lower.In that sense,root zone heating is more energy-saving than traditional air heating.The current work was devoted to the study of the effect of two root zone heating systems based on carbon crystal electrothermal film and low temperature hot water pipe on the microclimate and tomato yield in solar greenhouse.And their performance was tested in the coldest period of winter in Yongqing County of Hebei Province.The results showed that the use of root zone heating system can improve the average substrate temperature by 6.8℃.This microclimate improvement had a positive impact on tomato production.The output per square meter has increased by 19%compared to the unheated.It was also noted that the presence of root zone heating leads to a decrease in the development of disease in heated areas.Based on these results,the root zone heating system can be an effective method of improving the environmental temperature of crop plant,which is of great significance for increasing crop yield. | Fen He Jing Tian Liu Wang Yong Hou Fei Qi Yanping Zhang Libao Zhu Zhonghua Li | 2022 | International Journal of Agricultural and Biological Engineering2022,15,6: | 1 |

| 20 | Photophysical and photosensitive properties of Elsinochrome A显示文摘In this paper, the photophysical and photosensitive properties of Elsinochrome A (EA), another member of perylenequinone photosensitizers derived via artificially biological synthesis, were stud- ied by taking hypocrellin A (HA) and hypocrellin B (HB) as the references. It was found that the quantum yield of singlet oxygen produced via the photosensi- tization of EA was 0.98 with HB (0.84) as a reference. Furthermore, the semiquinone anion could be pro- duced via photosensitization of EA in oxygen-free solution. Besides, taking advantage of nanosecond time-resolved spectral technique, the transient triplet absorption spectra and the lifetime of EA in cyclo- hexane were determined by the use of the ground- state depletion method. | LI Cong HE Yanping OU Lingcheng TIAN Maojun YAO Zhikun GUO Mengbi | 2006 | Chinese Science Bulletin2006,51,9: | 1 |
