1A Domestication-Associated Gene GmPRR3b Regulates the Circadian Clock and Flowering Time in Soybean显示文摘Improved soybean cultivars have been adapted to grow at a wide range of latitudes,enabling expansion of cultivation worldwide.However,the genetic basis of this broad adaptation is still not clear.Here,we report the identification of GmPRR3b as a major flowering time regulatory gene that has been selected during domestication and genetic improvement for geographic expansion.Through a genome-wide association study of a diverse soybean landrace panel consisting of 279 accessions,we identified 16 candidate quantitative loci associated with flowering time and maturity time.The strongest signal resides in the known flowering gene E2,verifying the effectiveness of our approach.We detected strong signals associated with both flowering and maturity time in a genomic region containing GmPRR3b.Haplotype analysis revealed that GmPRR3bH6 is the major form of GmPRR3b that has been utilized during recent breeding of modern cultivars.mRNA profiling analysis showed that GmPRR3bH6 displays rhythmic and photoperiod-dependent expression and is preferentially induced under long-day conditions.Overexpression of GmPRR3bH6 increased main stem node number and yield,while knockout of GmPRR3bH6 using CRISPR/Cas9 technology delayed growth and the floral transition.GmPRR3bH6 appears to act as a transcriptional repressor of multiple predicted circadian clock genes,including GmCCAIa,which directly upregulates J/GmELF3a to modulate flowering time.The causal SNP(Chr12:5520945)likely endows GmPRR3bH6 a moderate but appropriate level of activity,leading to early flowering and vigorous growth traits preferentially selected during broad adaptation of landraces and improvement of cultivars.Cong Li Ying-hui Li Yanfei Li Hongfeng Lu Huilong Hong Yu Tian Hongyu Li Tao Zhao Xiaowei Zhou Jun Liu Xinan Zhou Scott A.Jackson Bin Liu Li-juan Qiu 2020Molecular Plant2020,13,5:11
2Why Was the Strengthening of Rainfall in Summer over the Yangtze River Valley in 2016 Less Pronounced than that in 1998 under Similar Preceding El Nino Events?Role of Midlatitude Circulation in August显示文摘It is widely recognized that rainfall over the Yangtze River valley(YRV) strengthens considerably during the decaying summer of El Ni ?no,as demonstrated by the catastrophic flooding suffered in the summer of 1998.Nevertheless,the rainfall over the YRV in the summer of 2016 was much weaker than that in 1998,despite the intensity of the 2016 El Nio having been as strong as that in 1998.A thorough comparison of the YRV summer rainfall anomaly between 2016 and 1998 suggests that the difference was caused by the sub-seasonal variation in the YRV rainfall anomaly between these two years,principally in August.The precipitation anomaly was negative in August 2016—different to the positive anomaly of 1998.Further analysis suggests that the weaker YRV rainfall in August 2016 could be attributable to the distinct circulation anomalies over the midlatitudes.The intensified 'Silk Road Pattern' and upper-tropospheric geopotential height over the Urals region,both at their strongest since 1980,resulted in an anticyclonic circulation anomaly over midlatitude East Asia with anomalous easterly flow over the middle-to-lower reaches of the YRV in the lower troposphere.This easterly flow reduced the climatological wind,weakened the water vapor transport,and induced the weaker YRV rainfall in August 2016,as compared to that in 1998.Given the unique sub-seasonal variation of the YRV rainfall in summer 2016,more attention should be paid to midlatitude circulation—besides the signal in the tropics—to further our understanding of the predictability and variation of YRV summer rainfall.chaofan li wei chen xiaowei hong riyu lu 2017Advances in Atmospheric Sciences2017,34,11:10
3Characteristics and composition of particulate matter from coal-fired power plants显示文摘Measurements of the characteristics of particulate matter(PM)were performed at the inlet and outlet of the electrostatic precipitators(ESP)of four boilers in two full-scale pulverized coal power plants.PM was collected with a 13-stages low-pressure-impactor(LPI)having aerodynamic cut-off diameter ranging from 10.0 to 0.03μm for a size-segregated collection.The properties of PM including its con-centration,mass size distribution,emission characteristics,percent penetration of PM through ESP and elemental composition were investigated.The experimental results indicate that,in all the cases the mass size distribution of PM10 had typical bimodal.PM1 contained up to 1.15wt% of the total particle(TP)generated in the boilers.PM2.5 contained about 2wt%―7wt% of the TP and PM10 contained about 4wt%―19wt% of the TP.When additive limestone used for desulphurization as sorbent besides PM generated from coal combustion,there was new PM generated from limestone.Penetration as a func-tion of particle diameter had a clear peak in particle size ranging from 0.2 to 0.6μm.Particles in the submicrometer size range were much more difficult to be collected with ESP than larger particles.Dis-tributions of individual elements within PM10 were different.LIU XiaoWei XU MingHou YAO Hong YU DunXi ZHANG ZhongHua LüDangZhen 2009Science China(Technological Sciences)2009,52,6:7
4Variation in Summer Surface Air Temperature over Northeast Asia and Its Associated Circulation Anomalies显示文摘This study investigates the interannual variation of summer surface air temperature over Northeast Asia(NEA) and its associated circulation anomalies.Two leading modes for the temperature variability over NEA are obtained by EOF analysis.The first EOF mode is characterized by a homogeneous temperature anomaly over NEA and therefore is called the NEA mode.This anomaly extends from southeast of Lake Baikal to Japan,with a central area in Northeast China.The second EOF mode is characterized by a seesaw pattern,showing a contrasting distribution between East Asia(specifically including the Changbai Mountains in Northeast China,Korea,and Japan) and north of this region.This mode is named the East Asia(EA) mode.Both modes contribute equivalently to the temperature variability in EA.The two leading modes are associated with different circulation anomalies.A warm NEA mode is associated with a positive geopotential height anomaly over NEA and thus a weakened upper-tropospheric westerly jet.On the other hand,a warm EA mode is related to a positive height anomaly over EA and a northward displaced jet.In addition,the NEA mode tends to be related to the Eurasian teleconnection pattern,while the EA mode is associated with the East Asia-Pacific/PacificJapan pattern.Wei CHEN Xiaowei HONG Riyu LU Aifen JIN Shizhu JIN Jae-Cheol NAM Jin-Ho SHIN Tae-Young GOO Baek-Jo KIM 2016Advances in Atmospheric Sciences2016,33,1:6
5Asymmetric Relationship between the Meridional Displacement of the Asian Westerly Jet and the Silk Road Pattern显示文摘In previous work, a significant relationship was identified between the meridional displacement of the Asian westerly jet(JMD) and the Silk Road Pattern(SRP) in summer. The present study reveals that this relationship is robust in northward JMD years but absent in southward JMD years. In other words, the amplitude of the SRP increases with northward displacement of the jet but shows little change with southward displacement. Further analysis indicates that, in northward JMD years, the Rossby wave source(RWS) anomalies, which are primarily contributed by the planetary vortex stretching, are significantly stronger around the entrance of the Asian jet, i.e., the Mediterranean Sea–Caspian Sea area, with the spatial distribution being consistent with that related to the SRP. By contrast, in southward JMD years, the RWS anomalies are much weaker.Therefore, this study suggests that the RWS plays a crucial role in inducing the asymmetry of the JMD–SRP relationship.The results imply that climate anomalies may be stronger in strongly northward-displaced JMD years due to the concurrence of the JMD and SRP, and thus more attention should be paid to these years.Xiaowei HONG Riyu LU Shuanglin LI 2018Advances in Atmospheric Sciences2018,35,4:6
6Effective identification of the three particle modes generated during pulverized coal combustion显示文摘Based on the mass fraction size distribution of aluminum (Al),an improved method for effectively identifying the modes of particulate matter from pulverized coal combustion is proposed in this study. It is found that the particle size distributions of coal-derived particulate matter actually have three modes, rather than just mere two.The ultrafine mode is mainly generated through the vaporization and condensation processes.The coarse mode is primarily formed by the coalescence of molten minerals, while the newly-found central mode is attributed to the heterogeneous condensation or adsorption of vaporized species on fine residual ash particles.The detailed investigation of the mass fraction size distribution of sulfur(S) further demonstrates the rationality and effectiveness of the mass fraction size distribution of the Al in identifying three particle modes.The results show that not only can the number of particle modes be identified in the mass fraction size distributions of the Al but also can their size boundaries be more accurately defined. This method provides new insights in elucidating particle formation mechanisms and their physico-chemical characteristics.YU DunXi XU MingHou YAO Hong LIU XiaoWei ZHOU Ke 2008Chinese Science Bulletin2008,53,10:5
7The study of migration of bone mesenchymal stem cells transplanted in intervertebral discs of rabbits and expression of exogenous gene显示文摘Objective: To explore the survival and migration of bone mesenchymal stem cells transplantated in intervertebral disc of rabbits and expression of the exogenic genes. Methods: Thirty-two rabbits were used, A randomized block design was used and discs in the same rabbit were one block,the lumbar discs from L2-3 to L5-6 were randomly divided into blank group, saline group, cell transplantation groupⅠ and cell transplantation groupⅡ. The fluorescence microscopy was used to determine the fluorescence of the maker protein GFP and DNA-PCR was used to analyze the copies of DNA of neomycin-resistant gene at 1, 3, 6, months after transplantation. Results: There was fluorescence in cell transplantation group Ⅰand Ⅱ and none in blank group, saline group at 1, 3, 6 months after transplantation. In cell transplantation groups,the fluorescent distribution was more scatter with time, but no significant difference between cell groups Ⅰand Ⅱ. The test of neomycin resistant gene expressed in cell transplantation group ⅠandⅡ and quantitative analysis showed that there was no significant difference between the cell groups Ⅰand Ⅱ(P > 0.05). Conclusion: The transplanted bone mesenchymal stem cells can survive, migrate and the transfer genes can express efficiently, it suggests that the BMSC therapy may be effective to prevent and treat intervertebral disc degeneration.Jintang Wang Hong Zhang Yingang Zhang Xiaowei Zhang Meng Li 2006Journal of Nanjing Medical University2006,20,5:4
8Size distributions of major elements in residual ash particles from coal combustion显示文摘Combustion experiments for three coals of different ranks were conducted in an electrically-heated drop tube furnace. The size distributions of major elements in the residual ash particles (>0.4μm) such as Al, Si, S, P, Na, Mg, K, Ca and Fe were investigated. The experimental results showed that the con-centrations of Al and Si in the residual ash particles decreased with decreasing particle size, while the concentrations of S and P increased with decreasing particle size. No consistent size distributions were obtained for Na, Mg, K, Ca and Fe. The established deposition model accounting for trace element dis-tributions was demonstrated to be applicable to some major elements as well. The modeling results indicated that the size distributions of the refractory elements, Al and Si, were mainly influenced by the deposition of vaporized elements on particle surfaces. A dominant fraction of S and P vaporized during coal combustion. Their size distributions were determined by surface condensation, reaction or adsorption. The partitioning mechanisms of Na, Mg, K, Ca and Fe were more complex.YU DunXi XU MingHou YAO Hong LIU XiaoWei 2009Chinese Science Bulletin2009,54,6:4
9A novel Co(phen)_2/C catalyst for the oxygen electrode in rechargeable lithium air batteries显示文摘A novel Co(phen)2/C catalyst was prepared by coating cobalt(II) phenanthroline (phen) chelate on BP2000 carbon black and then heat treating in an inert atmosphere. The obtained Co(phen)2/C product with 1.0 wt% cobalt loading exhibits similar morphology and porosity characteristics to those of the bare BP2000. X-ray diffraction measurements demonstrate a face-centered cubic (fcc) α-Co phase embedded in the carbon support after pyrolysis. Charge/discharge tests of the lithium-oxygen cells using the prepared Co(phen)2/C catalyst show high discharge capacities of 4870 mAh g-1 (0.05 mA cm-2 ), 3353 mAh g-1 (0.1 mA cm-2 ) and 3220 mAh g 1 (0.15 mA cm-2 ), respectively. The Co(phen) 2 /C cathode exhibits reasonable reversibility with capacity retention of 1401 mAh g-1 ( 0.1 mA cm-2 ) after 10 cycles. The superior electrochemical performance of the prepared Co(phen)2/C catalyst and low cost of the phenanthroline chelating agent indicate that Co(phen)2/C is a promising cheap catalyst for lithium-air batteries.WANG Hong LIAO XiaoZhen JIANG QiZhong YANG XiaoWei HE YuShi Ma ZiFeng 2012Chinese Science Bulletin2012,57,16:4
10Chlorination strategy on polymer donors toward efficient solar conversions显示文摘Bulk heterojunction(BHJ)polymer solar cells(PSCs)are promising candidates for next-generation solar cells.Benefitting from the persistent efforts in material design and synthesis,systematic device engineering and fundamental understanding of the device physics,the power conversion efficiency(PCE)of single PSC has been pushed to surpass 15%,and that of the tandem PSCs is over 17%.Recently,chlorination has drawn much interest and the chlorinated PSCs have been frequently reported in donor-acceptor(D-A)type conjugated polymers.This review summarizes the recent progress of the chlorinated strategy for highly efficient photovoltaic applications.We firstly discuss the chlorination on the acceptor units in D-A type donor polymers,emphasizing the 4 widely used acceptor units with their improved PCE.secondly,the chlorination on the donor units will be discussed,mainly focusing on the chlorination of benzo[1,2-b:4,b]dithiophene(BDT)unit and 2,2-bithiophene unit.Remarkably,the PCE of the chlorinated BDT-based device has been improved to over 14%.Overall,this review discusses the structure-property correlations of these chlorinated polymers in photovoltaic study,which could further provide guidance on the chlorinated strategy and the molecular design for high-performance photovoltaic devices.Pengjie Chao Nicolas Johner Xiaowei Zhong Hong Meng Feng He 2019Journal of Energy Chemistry2019,28,12:4

13Simulated Influence of the Atlantic Multidecadal Oscillation on Summer Eurasian Nonuniform Warming since the Mid-1990s显示文摘Based on ensemble experiments with three atmospheric general circulation models(AGCMs), this study investigates the role of the Atlantic Multidecadal Oscillation(AMO) in shaping the summer nonuniform warming over the Eurasian continent since the mid-1990 s. The results validate that the positive-phase AMO can indeed cause nonuniform warming,with predominant amplified warming over Europe–West Asia and Northeast Asia, but with much weaker warming over Central Asia. The underlying mechanism is then diagnosed from the perspective that the boundary forcing modulates the intrinsic atmospheric variability. The results highlight the role of the Silk Road Pattern(SRP), an intrinsic teleconnection pattern across the subtropical Eurasian continent propagating along the Asian jet. The SRP can not only be identified from the AGCM control experiments with the climatological sea surface temperature(SST), but can also be simulated by the AMO-related SST anomaly(SSTA) forcing. Furthermore, diagnostic linear baroclinic model experiments are conducted, and the results suggest that the SRP can be triggered by the AMO-related tropical diabatic heating. The AMO-triggered SRP-like responses feature anticyclonic circulations over Europe–West Asia and Northeast Asia, but cyclonic circulation over Central Asia. These responses cause increased warm advection towards Europe–West Asia and Northeast Asia, reduced precipitation and cloud cover, and then increased downward shortwave radiation. This increased warm advection and increased downward shortwave radiation together cause amplified warming in Europe–West Asia and Northeast Asia. The situation is opposite for Central Asia.Xueqian SUN Shuanglin LI Xiaowei HONG Riyu LU 2019Advances in Atmospheric Sciences2019,36,8:3
14Multi-interface collaboration of graphene cross-linked NiS-NiS_(2)-Ni_(3)S_(4) polymorph foam towards robust hydrogen evolution in alkaline electrolyte显示文摘Electrocatalytic hydrogen production in alkaline media is extensively adopted in industry. Unfortunately, further performance improvement is severely impeded by the retarded kinetics, which requires the fine regulation of water dissociation, hydrogen recombination, and hydroxyl desorption. Herein, we develop a multi-interface engineering strategy to make an elaborate balance for the alkaline hydrogen evolution reaction (HER) kinetics. The graphene cross-linked three-phase nickel sulfide (NiS-NiS_(2)-Ni_(3)S_(4)) polymorph foam (G-NNNF) was constructed through hydrothermal sulfidation of graphene wrapped nickel foam as a three-dimensional (3D) scaffold template. The G-NNNF exhibits superior catalytic activity toward HER in alkaline electrolyte, which only requires an overpotential of 68 mV to drive 10 mA·cm^(−2) and is better than most of the recently reported metal sulfides catalysts. Density functional theory (DFT) calculations verify the interfaces between nickel sulfides (NiS/NiS_(2)-Ni_(3)S_(4)) and cross-linked graphene can endow the electrocatalyst with preferable hydrogen adsorption as well as metallic nature. In addition, the electron transfer from Ni_(3)S_(4)/NiS_(2) to NiS results in the electron accumulation on NiS and the hole accumulation on Ni_(3)S_(4)/NiS_(2), respectively. The electron accumulation on NiS favors the optimization of the H* adsorption, whereas the hole accumulation on Ni_(3)S_(4) is beneficial for the adsorption of H_(2)O. The work about multi-interface collaboration pushes forward the frontier of excellent polymorph catalysts design.Haiqing Wang Wenjing Zhang Xiaowei Zhang Shuxian Hu Zhicheng Zhang Weijia Zhou Hong Liu 2021Nano Research2021,14,12:3
15Upper-and Lower-tropospheric Circulation Anomalies Associated with Interannual Variation of Pakistan Rainfall during Summer显示文摘This study investigated the large-scale circulation anomalies,in both the upper and lower troposphere,associated with the interannual variation of rainfall in Pakistan during summer,using the station observation data in this country and circulation data of the NCEP−NCAR reanalysis from 1981 to 2017.Results showed that the upper-and lower-tropospheric circulation anomalies associated with monthly rainfall variability exhibit similar features from June to August,so analyses were performed on June−August circulation and Pakistan rainfall data.The analyzed results indicated that summer rainfall in Pakistan is enhanced when there is an anticyclonic anomaly to the northwest of Pakistan in the upper troposphere and easterly anomalies along the southern foothills of the Himalayas in the lower troposphere,and vice versa.These upper-and lower-tropospheric circulation anomalies were found to be related,but show unique features.The upper-tropospheric anticyclonic anomaly is closely related to the Silk Road Pattern along the Asian westerly jet,while the lower-tropospheric easterly anomalies are related to the cyclonic anomaly to the south of Pakistan,i.e.,intensified South Asian monsoon trough.The results presented here suggest that the interannual variability of summer rainfall in Pakistan is a combined result of upper-and lower-tropospheric circulation anomalies,and of extratropical and tropical circulation anomalies.Riyu LU Saadia HINA Xiaowei HONG 2020Advances in Atmospheric Sciences2020,37,11:2
162021 Chinese consensus on the diagnosis and management of primary immune thrombocytopenia in pregnancy显示文摘Immune thrombocytopenia(ITP)is an acquired disease characterized by isolated thrombocytopenia,which is one of the most common causes of thrombocytopenia during pregnancy.Women with ITP who have severe thrombocytopenia are at an increased risk for life-threatening obstetric complications.Therefore,we established this consensus statement on the diagnosis and management of ITP during pregnancy(detailed information is available in the Supplementary File,http://gffzz16e312a87a7141a5hvqxppufcvckb69b5.ffgz.tsg.suse.edu.cn/A978).Zhang Xiaohui Chen Fangping Chen Xiequn Cheng Yunfeng Fang Meiyun Feng Jianming Fu Haixia Gao Hong Han Yue He Aili Hou Ming Hu Yu Huang Ruibin Huang Wenrong Jing Zhicheng Kong Peiyan Liang Aibin Liang Meiying Liu Daihong Liu Junling Liu Lin Liu Xiaowei Ma Liangming Mei Heng Ni Heyu Niu Ting Peng Jun Qiao Jianlin Ren Jinhai Song Yongping Tang Liang V Tong Tong Wang Shaoyuan Wang Xin Wang Zhao Wei Hui Wu Depei Wu Guangsheng Xu Caigang Xu Xue Xu Yajing Yang Linhua Yang Renchi Yang Tonghua Yin Chenghong Yu Li Zhang Guangsen Zhang Lei Zhang Liansheng Zhang Xi Zhao Weili Zhao Yongqiang Zhou Daobin Zhou Hu Zhou Zeping Zhu Tienan Wang Jianliu Huang Xiaojun 2022Chinese Medical Journal2022,,8:2

18Toxicity mechanisms and bioavailability of copper to fish based on an adverse outcome pathway analysis显示文摘Copper(Cu)exists in a variety of forms in different aquatic environments,and affects their bioavailability.In this study we provide a systematic review on toxicity of Cu which focuses on identifying evidence in the mechanisms of Cu toxicity,and apply an adverse outcome pathway(AOP)analysis to identify multiple potential mechanisms and their interactions of Cu toxicity to fish.This analysis process included the mechanisms of behavior toxicant,oxidative toxicant,ion regulation disruption toxicity,as well as endocrine disruption toxicity.It was found that at low levels of Cu exposure,swimming,avoid predators,locating prey and other sensory functions will be impaired,and the organism will suffer from metabolic alkalosis and respiratory acidosis following the inhibition of the carbonic anhydrase active.The main pathway of acute toxicity of Cu to fish is the inhibition of the Na^(+)/K^(+)-ATPase enzyme,and lead to reduced intracellular sodium absorption,as well as Cu-induced increased cell permeability,in turn resulting in increased sodium ion loss,leading to cardiovascular collapse and respiratory insufficiency.The endocrine disruption toxicity of Cu to fish caused growth inhibition and reproductive reduction.In addition,there are several key pathways of Cu toxicity that are affected by hardness(e.g.,Ca^(2+))and intracellular DOC concentrations,including inhibiting Cu-induction,improving branchial gas exchange,altering membrane transport functions,decreasing Na+loss,and increasing Na+uptake.The results of the AOP analysis will provide a robust framework for future directed research on the mechanisms of Cu toxicity.Wei Liao Ziwei Zhu Chenglian Feng Zhenfei Yan Yajun Hong Daqing Liu Xiaowei Jin 2023Journal of Environmental Sciences2023,,5:1
