| 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 | Fluid Flow in Tundish Due to Different Type Arrangement of Weir and Dam显示文摘Tundish is an important metallurgical reactor in the continuous casting process. In order to control the fluid flow in tundish and thus take full advantage of the residence time available for the removal of inclusions from molten steel, the effect of weir and dam on the fluid flow has been studied in a water model based on the characteristic number Froude and Reynold number similarity criteria. The residence time distribution curves of the flow were measured by SG800, The optimum arrangement of dam and weir and the non- stationary flow in tundish were discussed. The results show that the combination of weir and dam is benefit for the flow pattern in tundish, weir can prevent the upper recirculating flow, dam can cut off the bottom flow and turn to upwards, it is advantageous to separate the nonmetallic inclusions. Furthermore, it is important to exceed the critical depth of bath during exchange ladles, not only for the inclusion floatation but also for avoiding tundish slag drainage earlier. | Yanping Bao, Wei Jiang,Baomei Xu, Haizhong Zhang Metallurgy School, University of Science and Technology Beijing, Beijing 100083, China E-mail: baoyp@metall .ustb .edu. cn | 2002 | Journal of University of Science and Technology Beijing2002，9，1： | 8 |

| 4 | The effects of air temperature and precipitation on the net primary productivity in China during the early 21st century显示文摘Research on how terrestrial ecosystems respond to climate change can reveal the complex interactions between vegetation and climate,net primary productivity (NPP),an important vegetation parameter and ecological indicator,fluctuates within any given ecological environment or regional carbon budget.In this study, spatial interpolation was used to generate a spatial dataset, with 1-km spatial resolution,with meteorological data from 736 observation stations across China.An improved CASA model was used to simulate NPP over the period of 2001-2013 by taking into account land-cover change in every year during the same period.We propose the grid- based spatial patterns and dynamics of annual NPP,annual average temperature,and annual total precipitation based on the model.We also used the model to demonstrate the spatial correlation between NPP,temperature,and pre- cipitation in the study area with special focus on the impact of climate change in the early 21st century.Results showed that the spatial pattern of NPP over all of China is characterized by higher values in the southeast and lower values in the northwest.The spatial pattern of temperature indicates substantial latitudinal differences across the country,and the spatial pattem of precipitation shows a ribbon of decline from the southeast coast to the northwest inland.Most areas show an upward trend in NPP. Temperatures appear to decrease across the country during the global warming hiatus (1998-2008),and are accom- panied by an increase in precipitation over most regions.The correlation between NPP and annual average temperature is weak.Alternatively,NPP and annual total precipitation are positively correlated in northern and central China at a coefficient above 0.64(p <0.01)yet negatively correlated in the eastem parts of the Qinghai- Tibet Plateau and Sichuan Basin.Results can provide useful information for improving parameters for calibra- tion of the terrestrial ecosystem process model. | Qianfeng WANG Jingyu ZENG Song LENG Bingxiong FAN Jia TANG Cong JIANGs Yi HUANG Qing ZHANG Yanping QU Wnlin WANG Wei SHUI | 2018 | Frontiers of Earth Science2018，12，4： | 6 |
| 5 | Phenotypic identification of peanut germplasm for resistance to southern stem rot显示文摘Southern stem rot,caused by Sclerotium rolfsii Sacc.,is a destructive soil fungal disease of peanut in China and other countries.To evaluate resistant germplasm,a total of 256 peanut accessions were investigated on their resistance to southern stem rot in 3 environments by artificial inoculation.Variance analysis indicated that disease index was significantly influenced by environment,genotype and genotypeenvironment interactions.Peanut accessions of var.vulgaris type exhibited higher resistance to southern stem rot.Disease index was significantly negatively correlated with linoleic acid content,while positively correlated with oleic acid content.Six resistant accessions were identified,including Hua 28,Shandongzai,ICG 6326,Quanhua 7,Quanhua 9 and Guihua 836,with their disease indexes under 40 and mortality were less than 30%in the three environments.The identified resistant accessions showed the great potential to be applied in resistant peanut breeding,and would be good genetic resources for enhancing the resistance to southern stem rot. | Pengmin Fan Wanduo Song Yanping Kang Liyun Wan Yong Lei Dongxin Huai Yuning Chen Xin Wang Huifang Jiang Liying Yan Boshou Liao | 2020 | Oil Crop Science2020，5，4： | 3 |
| 6 | Cloning of Porcine Lactoferrin Gene and Construction of Expression System in Recombinant Lactobacillus显示文摘Lactobacillus was selected as a bacterial carrier for expression of N-lobe of porcine lactoferrin(PLF N) . A pair of primers was designed with Oligo6.0 and used to amplify PLF N gene. It was in accordance with the characters of translational fusions from gene and expression vector plasmid. A 1 077 bp fragment of the gene from PLF was cloned from mammary gland tissue of the lactating sow on the third day by RT-PCR;the gene was connected with the vector plasmid pPG612.1 and transformed into the host strain JM109. The recombinant expression vector plasmid pPG612-PLF N was created and identified by using plasmid extraction,PCR,restriction enzyme digestion and sequence analysis. The recombinant plasmid was transformed into Lactobacillus casei ATCC393,Lactobacillus plantarum KLDS 1.0344,Lactobacillus paracasei KLDS 1.0652 and Lactobacillus pentosus KLDS1.0413 by electroporation,and produced the recombinant strains of pPG612-PLF N /L. casei,pPG612-PLF N /L. plantarum,pPG612-PLF N /L. paracasei and pPG612-PLF N /L. pentosus,respectively. The results indicated that PLF N gene had inserted into the expression vectors and achieved multiple Lactobacillus expression systems. It electes the base for the expression and production of recombinant porcine lactoferrin in Lactobacillus. | ZONG Xiaolin HA Zhuo ZHAO Lili LIU Diqiu QIAO Xinyuan JIANG Yanping GE Junwei LI Yijing TANG Lijie | 2011 | Journal of Northeast Agricultural University(English Edition)2011，18，4： | 3 |
| 7 | Effect of the Oxidation Time on Properties of Ceramic Coatings Produced on Ti-6Al-4V by Micro-Arc Oxidation显示文摘Ceramic coatings were prepared on Ti-6AI-4V alloy using ac micro-arc oxidation (MAO) in silicate-hypophosphate solution. Growth regularity and formation mechanism of ceramic coatings were discussed. It was found that during the first stage the growth rate of coatings toward the external surface was larger than that toward substrate and then the coating began to grow mainly towards Ti alloy. When the total coating thickness reaches a certain value, it would no longer increase. In addition, the variations of the composition and microstructure of ceramic coatings according to the depositing time were also investigated with X-ray diffraction (XRD) and scanning electron microscope (SEM).The amount of rutile TiO2 gradually increased, whereas the amounts of the anatase TiO2 and amorphous phases first increased and then decreased slightly. | Zhaohua JIANG, Xuetong SUN, Yanping LI, Fuping WANG and Yandong LU Department of Applied Chemistry, Harbin Institute of Technology, Harbin 150001, China | 2005 | Journal of Materials Science & Technology2005，21，2： | 3 |
| 8 | Transmissible hypovirulent element in isolate Ep-1PN of Sclerotinia sclerotiorum显示文摘The cause of virulence decline of hypovirulent isolate Ep-1PN of Sclerotinia sclerotiorum (Lib.) de Bary has been studied through transmitting test and analysing its offsprings derived from single ascospore. When the colony of a normal strain Ep-1PNA 183 intermingled with the colony of Ep-1PN, its margin became abnormal, just like Ep-1PN. Cultures isolated from top-tip of the colony of Ep-1PNA 183 showed the hypovirulence and its associated properties of Ep-1PN. Moreover, a series of cultures which have characteristics between Ep-1PN and normal strain could be isolated from stipes of Ep-1PN. More than 200 offsprings derived from single ascospore of Ep-1PN were normal strains. According to those results, there exists a transmissible cytoplasmic hypovirulent element in hypovirulent isolate Ep-1PN of S. sclerotiorum. | Daohong Jiang Guoqing Li Yanping Fu Xianhong Yi Daoben Wang | 1998 | Chinese Science Bulletin1998，43，9： | 3 |
| 9 | Synthesis of novel substituted N-aryl benzamides as hA3G stabilizers and their inhibitory activities against hepatitis C virus replication显示文摘A series of novel amino-substituted N-aryl benzamide analogs were synthesized and evaluated for their ability to inhibit hepatitis C virus(HCV)replication in acutely infected Huh7.5 cells.Most of the substituted N-aryl benzamide compounds showed convincing anti-HCV activities.Compounds 1f,1g and 4c exhibited potent anti-replicative activity at low micromolar levels(IC_(50)=1.0–2.0μM)with selective indices(SI)greater than 40.Mechanistic analysis indicated that the active compounds increased intracellular hA3G protein levels and inhibited HCV replication in a dose-dependent manner.The results demonstrate that this series of substituted Naryl benzamide compounds warrant further investigation as inhibitors of HCV replication. | Yanping Li Zonggen Peng Lanhu Hao Zhouyi Wu Yanping Zhu Laixing Hu Jiandong Jiang Zhuorong Li | 2013 | Acta Pharmaceutica Sinica B2013，3，5： | 2 |
| 10 | Genetic diversity of atoxigenic Aspergillus flavus isolates from peanut kernels in China显示文摘Aflatoxin contamination in peanuts is a major threat to public health, especially in tropical and subtropical regions of the world. Recently, the use of atoxigenic Aspergillus flavus strains as biological control agents prove to be effective in reducing aflatoxin contamination in crops. A total of 208 atoxigenic A. flavus isolates, collected from peanut kernels, were grouped into 7 deletion patterns by quadruplex PCR products of nor-1, ver-1, aflR and omtA genes. 49 SNPs, found in 1254 bp fragment of omtA gene, showed genetic variation of omtA among different A. flavus isolates. These isolates were assigned to either MAT1-1 type or MAT1-2 type with primers for each MAT locus. Thus, rich genetic diversity was found in the atoxigenic A. flavus isolates of peanut in China. The results indicated that quadruplex PCR would be an effective method for rapid screening of atoxigenic isolates with gene deletion in aflatoxin biosynthetic cluster. | Liying Yan Yanping Kang Yong Lei Liyun Wan Dongxin Huai Huifang Jiang Xiaoping Ren Boshou Liao | 2018 | Oil Crop Science2018，3，1： | 2 |
| 11 | Long-term variation of storm surge-associated waves in the Bohai Sea显示文摘When investigating the long-term variation of wave characteristics as associated with storm surges in the Bohai Sea,the Simulating Waves Nearshore(SWAN)model and Advanced CIRCulation(ADCIRC)model were coupled to simulate 32 storm surges between 1985 and 2014.This simulation was validated by reproducing three actual wave processes,showing that the simulated significant wave height(SWH)and mean wave period agreed well with the actual measurements.In addition,the long-term variations in SWH,pattems in SWH extremes along the Bohai Sea coast,the 100-year retum period SWH extreme distribution,and waves conditional probability distribution were calculated and analyzed.We find that the trend of SWH extremes in most of the coastal stations was negative,among which the largest trend was-0.03 m/a in the western part of Liaodong Bay.From the 100-year return period of the SWH distribution calculated in the Gumbel method,we find that the SWH extremes associated with storm surges decreased gradually from the center of the Bohai Sea to the coast.In addition,the joint probability of wave and surge for the entire Bohai Sea in 100-year return period was determined by the Gumbel logistic method.We therefore,assuming a minimum surge of one meter across the entire Bohai Sea,obtained the spatial SWH distribution.The conclusions of this study are significant for offshore and coastal engineering design. | WANG Yanping LIU Yongling MAO Xinyan CHI Yutao JIANG Wensheng | 2019 | Journal of Oceanology and Limnology2019，37，6： | 2 |
| 12 | Direct demonstration of carrier distribution and recombination within step-bunched UV-LEDs显示文摘AlGaN-based solid state UV emitters have many advantages over conventional UV sources. However, UV-LEDs still suffer from numerous challenges, including low quantum efficiency compared to their blue LED counterparts. One of the inherent reasons is a lack of carrier localization effect inside fully miscible AlGaN alloys. In the pursuit of phase separation and carrier localization inside the active region of AlGaN UV-LED, utilization of highly misoriented substrates proves to be useful, yet the carrier distribution and recombination mechanism in such structures has seldom been reported. In this paper, a UV-LED with step-bunched surface morphology was designed and fabricated, and the internal mechanism of high internal quantum efficiency was studied in detail. The correlation between microscale current distribution and surface morphology was provided, directly demonstrating that current prefers to flow through the step edges of the epitaxial layers. Experimental results were further supported by numerical simulation. It was found that efficient radiative recombination centers were formed in the inclined quantum well regions. A schematic three-dimensional energy band structure of the multiple quantum wells(MQWs) across the step was proposed and helps in further understanding the luminescence behavior of LEDs grown on misoriented substrates. Finally, a general principle to achieve carrier localization was proposed, which is valid for most ternary Ⅲ-Ⅴ semiconductors exhibiting phase separation. | HOUQIANG XU JIEAN JIANG LI CHEN JASON HOO LONG YAN SHIPING GUO CAI SHEN YANPING WEI HUA SHAO ZI-HUI ZHANG WEI GUO JICHUN YE | 2021 | Photonics Research2021，9，5： | 2 |
| 13 | Br/Cl,I/Cl and chlorine isotopic compositions of pore water in shallow sediments:implications for the fluid sources in the Dongsha area,northern South China Sea显示文摘The Dongsha area is one of the most promising target areas for gas hydrate exploration in the South China Sea(SCS).The study of pore water geochemistry has played a key role in Chinese gas hydrate exploration.Br/Cl,I/Cl and δ37Cl in pore water were applied here in tracing gas hydrate occurrence,chemical evolution of pore fluids and water/rock interactions in low temperature sediment environments.The samples were collected from Sites HD255 PC and HD309 PC in the Dongsha area in 2004.At Site HD255 PC,we found the elevated Br/Cl,I/Cl and decreased SO_4/Cl at the depth of 4–5 m,suggestive of a laterally migrated fluid probably generated from the gas hydrate occurrence.The range of δ37Cl is –0.54‰ to +0.96‰,and positive δ^(37)Cl at 4–5 m interval should be related with different diffusion rates between ^(35)Cl and ^(37)Cl.At Site HD309 PC,a laterally migrated fluid was also found at the depth of 3–4 m,with the Br/Cl two times to that of the seawater and decreased I/Cl,indicating the fluid has no relationship with the gas hydrate.In this site,the chlorine isotopic composition varies from –0.7‰ to+1.9‰.Extra high Br/Cl might relate with the deep generated fluid.At higher temperature and pressure,the Br/Cl of the fluid is elevated during the hydrous silicate formation,while positive δ37Cl is also associated with the same mechanism. | LI Yanping JIANG Shaoyong YANG Tao | 2017 | Acta Oceanologica Sinica2017，36，4： | 2 |

| 15 | Microglia activation mediated by toll-like receptor-4 impairs brain white matter tracts in rats显示文摘Microglia activation and white matter injury coexist after repeated episodes of mild brain trauma and ischemic stroke. Axon degeneration and demyelination can activate microglia; however, it is unclear whether early microglia activation can impair the function of white matter tracts and lead to injury. Rat corpus callosum(CC) slices were treated with lipopolysaccharide(LPS) or LPS + Rhodobacter sphaeroides(RS)-LPS that is a toll-like receptor 4(TLR-4) antagonist. Functional changes reflected by the change of axon compound action potentials(CAPs) and the accumulation of β-amyloid precursor protein(β-APP) in CC nerve fibers. Microglia activation was monitored by ionized calcium binding adaptor-1 immunofluorescent stain, based on well-established morphological criteria and paralleled proportional area measurement. Input-output(I/O) curves of CAPs in response to increased stimuli were significantly downshifted in a dose-dependent manner in LPS(0.2, 0.5 and 1.0μg/mL)-treated slices, implying that axons neurophysiological function was undermined. LPS caused significant β-APP accumulation in CC tissues,reflecting the deterioration of fast axon transport. LPS-induced I/O curve downshift and P-APP accumulation were significantly reversed by the pre-treatment or co-incubation with RS-LPS. RS-LPS alone did not change the I/O curve.The degree of malfunction was correlated with microglia activation, as was shown by the measurements of proportional areas. Function of CC nerve fibers was evidently impaired by microglia activation and reversed by a TLP-4 antagonist, suggesting that the TLP-4 pathway lead to microglia activation. | Xinglong Yang Jingdong Zhang Lian Duan Huangui Xiong Yanping Jiang Houcheng Liang | 2018 | The Journal of Biomedical Research2018，32，2： | 2 |
| 16 | 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 |

| 19 | Human cytomegalovirus miR-US5-1 inhibits viral replication by targeting Geminin mRNA显示文摘Viruses commonly create favorable cellular conditions for their survival through multiple mechanisms. Micro RNAs(mi RNAs), which function as post-transcriptional regulators, are utilized by human cytomegalovirus(HCMV) in its infection and pathogenesis. In the present study, the DNA replication inhibitor Geminin(GMNN) was identified to be a direct target of hcmv-mi R-US5-1. Overexpression of hcmv-mi R-US5-1 could block the accumulation of GMNN during HCMV infection, and the decrease of GMNN expression caused by hcmv-mi R-US5-1 or GMNN specific si RNA reduced HCMV DNA copies in U373 cells. Meanwhile, ectopic expression of hcmv-mi R-US5-1 and consequent lower expression of GMNN influenced host cell cycle and proliferation. These results imply that hcmv-mi R-US5-1 may affect viral replication and host cellular environment by regulating expression kinetics of GMNN during HCMV infection. | Shujuan Jiang Yujing Huang Ying Qi Rong He Zhongyang Liu Yanping Ma Xin Guo Yaozhong Shao Zhengrong Sun Qiang Ruan | 2017 | Virologica Sinica2017，32，5： | 1 |
