1Feedback Regulation of FLC by FLOWERING LOCUS T (FT) and FD through a 5’ FLC Promoter Region in Arabidopsis显示文摘Dear Editor, Recently, it was reported that the florigenic FT protein bound to a 3’ region of the potent floral repressor FLC (FLOWERING LOCUS C) to activate the expression of long noncoding antisense RNAs known as COOLAIR and consequently repress FLC expression to control flowering time and seed dormancy in Arabidopsis (Chen and Penfield, 2018). Here, we show that FT represses FLC expression through a 5' promoter region, but not COOLAIR.Xiao Luo Tao Chen Xiaolin Zeng Dingwei He Yuehui He 2019Molecular Plant2019,12,3:10
2Differentiation potential of bone marrow mesenchymal stem cells in duck显示文摘The bone marrow mesenchymal stem cells(MSCs) are multipotent stem cells which can differentiate into mesenchymal cells in vitro.In this study,MSCs in duck were isolated from bone marrow by density gradient centrifuge separation,purified and expanded in the me-dium.The primary MSCs were expanded for 11 passages.The different-passage MSCs were induced to differentiate into osteoblasts and neuron-like cells.Karyotype analysis indicated that MSCs kept diploid condition and the hereditary feature was stable.The different-passage MSCs expressed CD44,ICAM-1 and SSEA-4,but not CD34,CD45 and SSEA-1 when detected by immunofluorescence staining.There was no significant difference among the positive rates of passages 2,6 and 8(P > 0.05),but a significant difference existed among those of passages 2,6,8 and 11(P < 0.05).After the osteogenic inducement was added,the induced different-passage MSCs expressed high-level alkaline phosphatase(ALP),and are positive for tetracycline staining,Alizarin Red staining and Von Kossa staining.After the neural inducement was added,about 70% cells exhibited typical neuron-like phenotype,the induced different-passage MSCs expressed Nestin,neuron-specific enolase(NSE) and glial fibrillary acidic protein(GFAP) when detected by immunofluorescence staining.There was no significant difference among the positive rates of passages 3,4 and 6(P>0.05),but a significant difference existed among those of passages 3,4,6 and 8(P<0.05).These results suggest that MSCs in duck were capable of differentiating into osteoblasts and neuron-like cells in vitro.Linfeng Li Xiujuan Bai Xuelian Gong Hongkun Liu Lina Chen Weijun Guan Yuehui Ma 2009Journal of Genetics and Genomics2009,36,3:8
3Uranium Provinces in China显示文摘Three uranium provinces are recognized in China, the Southeast China uranium province, the Northeast China-Inner Mongolia uranium province and the Northwest China (Xinjiang) uranium province. The latter two promise good potential for uranium resources and are major exploration target areas in recent years. There are two major types of uranium deposits: the Phanerozoic hydrothermal type (vein type) and the Meso-Cenozoic sandstone type in different proportions in the three uranium provinces. The most important reason or prerequisite for the formation of these uranium provinces is that Precambrian uranium-enriched old basement or its broken parts (median massifs) exists or once existed in these regions, and underwent strong tectonomagmatic activation during Phanerozoic time. Uranium was mobilized from the old basement and migrated upwards to the upper structural level together with the acidic magma originating from anatexis and the primary fluids, which were then mixed with meteoric water and resulted inCHEN Zhaobo ZHAO Fengmin XIANG Weidong CHEN Yuehui 2000Acta Geologica Sinica(English Edition)2000,74,3:7

6Rapid, automated, and reliable antimicrobial susceptibility test from positive blood culture by CAST‐R显示文摘Antimicrobial susceptibility tests(ASTs)are pivotal in combating multidrug resistant pathogens,yet they can be time‐consuming,labor‐intensive,and unstable.Using the AST of tigecycline for sepsis as the main model,here we establish an automated system of Clinical Antimicrobials Susceptibility Test Ramanometry(CAST‐R),based on D2O‐probed Raman microspectroscopy.Featuring a liquid robot for sample pretreatment and a machine learning‐based control scheme for data acquisition and quality control,the 3‐h,automated CAST‐R process accelerates AST by>10‐fold,processes 96 paralleled antibiotic‐exposure reactions,and produces high‐quality Raman spectra.The Expedited Minimal Inhibitory Concentration via Metabolic Activity is proposed as a quantitative and broadly applicable parameter for metabolism‐based AST,which shows 99%essential agreement and 93%categorical agreement with the broth microdilution method(BMD)when tested on 100 Acinetobacter baumannii isolates.Further tests on 26 clinically positive blood samples for eight antimicrobials,including tigecycline,meropenem,ceftazidime,ampicillin/sulbactam,oxacillin,clindamycin,vancomycin,and levofloxacin reveal 93%categorical agreement with BMD‐based results.The automation,speed,reliability,and general applicability of CAST‐R suggest its potential utility for guiding the clinical administration of antimicrobials.Pengfei Zhu Lihui Ren Ying Zhu Jing Dai Huijie Liu Yuli Mao Yuandong Li Yuehui He Xiaoshan Zheng Rongze Chen Xiaoting Fu Lili Zhang Lijun Sun Yuanqi Zhu Yuetong Ji Bo Ma Yingchun Xu Jian Xu Qiwen Yang 2022mLife2022,1,3:3
7Infrared-transmission spectra and hydrogen content of hydrogenated amorphous silicon显示文摘In this paper, two kinds of methods of calculating the hydrogen content of a-Si:H thin film by means of the wagging mode and the stretching modes of infrared-transmission spectra , are investigated. The reason for the difference in these two calculation results is analyzed. If the contents of SiH2 and (SiH2)n are indicated in terms of a structure factor F=(I840+I880)/I2000, it is shown that the calculation results obtained from the two different methods are almost equal when the refractive index n is approximately 3.4 or the fitting thickness is between 0.71 and 0.89 mm in the case of a small F. It is shown that the ways of fabrication of thin film can influence silicon-hydrogen bonding configuration of a-Si:H film, and different ways of fabrication can lead to different contents of SiH2 and (SiH2)n. The uniformity of the thin film with a big F is bad. In this case, there is great difference between the thickness measured by the SurfCom408A surface profile apparatus and the thickness obtained by fitting the fringes; and the hydrogen contents of a-Si:H films obtained by means of the wagging mode and the stretching modes are different, too. But the fabrication of the MWECR CVD assisted by CAT CVD can effectively restrain the formation of SiH2 and (SiH2)n.HU Yuehui CHEN Guanghua WU Yueying YIN Shengyi GAO Zhuo WANG Qing SONG Xuemei DENG Jinxiang 2004Science China(Physics,Mechanics & Astronomy)2004,47,3:3
8Molecular basis of CONSTANS oligomerization in FLOWERING LOCUS T activation显示文摘The transcription factor CONSTANS(CO)integrates day-length information to induce the expression of florigen FLOWERING LOCUS T(FT)in Arabidopsis.We recently reported that the C-terminal CCT domain of CO forms a complex with NUCLEAR FACTOR-YB/YC to recognize multiple cis-elements in the FT promoter,and the N-terminal tandem B-box domains form a homomultimeric assembly.However,the mechanism and biological function of CO multimerization remained unclear.Here,we report that CO takes on a head-to-tail oligomeric configuration via its B-boxes to mediate FT activation in long days.The crystal structure of B-boxesCOreveals a closely connected tandem B-box fold forming a continuous head-to-tail assembly through unique CDHH zinc fingers.Mutating the key residues involved in CO oligomerization resulted in a non-functional CO,as evidenced by the inability to rescue co mutants.By contrast,a transgene encoding a human p53-derived tetrameric peptide in place of the B-boxesCOrescued co mutant,emphasizing the essential role of BboxesCO-mediated oligomerization.Furthermore,we found that the four TGTG-bearing cis-elements in FT proximal promoter are required for FT activation in long days.Our results suggest that CO forms a multimer to bind to the four TGTG motifs in the FT promoter to mediate FT activation.Xiaolin Zeng Xinchen Lv Rui Liu Hang He Shiqi Liang Lixian Chen Fan Zhang Liu Chen Yuehui He Jiamu Du 2022Journal of Integrative Plant Biology2022,64,3:2
9How Many Packets Are Most Effective for Early Stage Traffic Identification: An Experimental Study显示文摘Accurately identifying network traffics at the early stage is very important for the application of traffic identification.Recent years,more and more research works have tried to build effective machine learning models to identify traffics with the few packets at the early stage.However,a basic and important problem is still unresolved,that is how many packets are most effective in early stage traffic identification.In this paper,we try to resolve this problem using experimental methods.We firstly extract the packet size of the first 2-10 packets of 3 traffic data sets.And then execute crossover identification experiments with different numbers of packets using 11 well-known machine learning classifiers.Finally,statistical tests are applied to find out which number is the best performed one.Our experimental results show that 5-7are the best packet numbers for early stage traffic identification.PENG Lizhi YANG Bo CHEN Yuehui WU Tong 2014China Communications2014,11,9:2
10Genetic and Epigenetic Understanding of the Seasonal Timing of Flowering显示文摘The developmental transition to flowering in many plants is timed by changing seasons,which enables plants to flower at a season that is favorable for seed production.Many plants grown at high latitudes perceive the seasonal cues of changing day length and/or winter cold(prolonged cold exposure),to regulate the expression of flowering-regulatory genes through the photoperiod pathway and/or vernalization pathway,and thus align flowering with a particular season.Recent studies in the model flowering plant Arabidopsis thaliana have revealed that diverse transcription factors engage various chromatin modifiers to regulate several key flowering-regulatory genes including FLOWERING LOCUS C(FLC)and FLOWERING LOCUS T(FT)in response to seasonal signals.Here,we summarize the current understanding of molecular and chromatin-regulatory or epigenetic mechanisms underlying the vernalization response and photoperiodic control of flowering in Arabidopsis.Moreover,the conservation and divergence of regulatory mechanisms for seasonal flowering in crops and other plants are briefly discussed.Yuehui He Tao Chen Xiaolin Zeng 2020Plant Communications2020,1,1:2
11Diffusion behavior of Nb element in high Nb containing TiAl Alloys by reactive hot pressing显示文摘Diffusion behavior of Nb in elemental powder metallurgy high Nb containing TiAl alloys was investigated. The results show that Nb element dissolves into the matrix by diffusion. Pore nests are formed in situ after Nb diffusion. With the increase in hot pressing temperature, the diffusion of Nb will be more sufficient, and the microstructure is more homo-geneous. Nb element diffuses completely at 1400°C. Meanwhile, compression deformation and agglomeration phenomena of pores are observed in some pore nests. Hot isostatic pressing (HIP) treatment can only efficiently decrease but not eliminate porosity completely.WANG Yanhang LIN Junpin HE Yuehui WANG Yanli CHEN Guoliang 2006Rare Metals2006,25,4:2

15Atomic-scale structural and chemical evolution of Li3V2(PO4)3 cathode cycled at high voltage window显示文摘Here,by using atomically resolved scanning transmission electron microscopy and electron energy loss spectroscopy,we investigate the structural and chemical evolution of Li3V2(PO4)3 (LVP) upon the high-voltage window (3.0-4.8 V).We find that the valence of vanadium gradually increases towards the core corresponding to the formation of electrochemically inactive Li3-xV2(PO4)3 (L3-xVP) phases.These Li-deficient phases exhibit structure distortion with superstructure stripes,likely caused by the migration of the vanadium,which can slow down the lithium ion diffusion or even block the diffusion channels.Such kinetic limitations lead to the formation of Li-deficient phase along with capacity loss.Thus,the LVP continuously losses of electrochemical activity and Li-deficient phases gradually grow from the particle core towards the surface during cycling.After 500 cycles,the thickness of active LVP layer decreases to be - 5-20 nm.Moreover,the micromorphology and chemical composition of solid electrolyte interphase (SEI) have been investigated,indicating the thick SEI film also contributes to the capacity loss.The present work reveals the structural and chemical evolution in the cycled electrode materials at an atomic scale,which is essential to understand the voltage fading and capacity decaying of LVP cathode.Shulin Chen Jian Zou Yuehui Li Ning Li Mei Wu Jinghuang Lin Jingmin Zhang Jian Cao Jicai Feng Xiaobin Niu Jianming Bai Junlei Qi Peng Gao Liping Wang Hong Li 2019Nano Research2019,12,7:1
