| 2 | A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding. | Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu | 2020 | Molecular Plant2020，13，9： | 14 |
| 3 | Broadband polarized photodetector based on p-BP/n-ReS2 heterojunction显示文摘Two-dimensional(2D) atomic crystals,such as graphene,black phosphorus(BP) and transition metal dichalcogenides(TMDCs) are attractive for use in optoelectronic devices,due to their unique crystal structures and optical absorption properties.In this study,we fabricated BP/ReS2 van der Waals(vdWs) heterojunction devices.The devices realized broadband photoresponse from visible to near infrared(NIR)(400–1800 nm) with stable and repeatable photoswitch characteristics,and the photoresponsivity reached 1.8 mA/W at 1550 nm.In addition,the polarization sensitive detection in the visible to NIR spectrum(532–1750 nm) was demonstrated,and the photodetector showed a highly polarization sensitive photocurrent with an anisotropy ratio as high as 6.44 at 1064 nm.Our study shows that van der Waals heterojunction is an effective way to realize the broadband polarization sensitive photodetection,which is of great significance to the realization and application of multi-functional devices based on 2D vdWs heterostructures. | Wenkai Zhu Xia Wei Faguang Yan Quanshan Lv Ce Hu Kaiyou Wang | 2019 | Journal of Semiconductors2019，40，9： | 6 |
| 4 | Cloning, expression and protective immunity evalua-tion of the full-length cDNA encoding succinate dehydrogenase iron-sulfur protein of Schistosoma japonicum显示文摘1071-bp fragment was obtained from the Schistosoma japonicum (Chinese strain) adult cDNA library after the 3′ and 5′ ends of the incomplete expression sequence tag (EST) of succinate dehydrogenase iron-sulfur protein of Schistosoma japonicum (SjSDISP) were amplified by the anchored PCR with 2 pairs of primers designed according to the EST of SjSDISP and the sequence of multiclone sites of the library vector. Sequence analysis indicated that the fragment was a full-length cDNA with a complete open reading frame (ORF), encoding 278 amino acid residues. The fragment was cloned into prokary- otic expression vector pQE30, and subsequently sequenced and expressed in Escherichia coli. SDS-PAGE and Western-blot analyses showed that the recombinant protein was about 32 kD and could be recognized by the polyclonal antisera from rabbits immunized with Schistosoma japonicum adult worm antigen. Compared with the FCA controls, mice vaccinated with rSjSDISP (test) or rSjGST (posi- tive control) all revealed high levels of specific antibody and significant reduction in worm burden, liver eggs per gram (LEPG), fecal eggs per gram (FEPG) and intrauterine eggs. These results suggest that SjSDISP may be a novel and partially protective vaccine candidate against schistosomiasis. In contrast to the worm burden reduction rate, the higher degree of egg reduction rate in the test group also sug- gested that SjSDISP vaccine may primarily play a role in anti-embryonation or anti-fecundity immunity. | YU JunLong, WANG ShiPing, LI WenKai, DAI Gan, XU ShaoRui, HE Zhuo, PENG XianChu, ZHOU SongHua & LIU XueQin Department of Parasitology, Xiangya School of Medicine, Central South University, Changsha 410078, China | 2007 | Science China(Life Sciences)2007，50，2： | 4 |

| 6 | Development of a SYBR-based real-time PCR to detect rabbit hemorrhagic disease virus(RHDV) and analyze its tissue distribution in experimentally infected rabbits显示文摘Dear Editor,Rabbit hemorrhagic disease(RHD)is a highly contagious disease of both wild and domesticated rabbits(Oryctolagus cuniculus).The causative agent of the disease is the rabbit hemorrhagic disease virus(RHDV),belongs to the genus Lagovirus within the family Caliciviridae(Granzow et al.,1996;Ohlinger et al.,1990).It is a small and non-enveloped virus with a 7.5 kb single stranded positive sense RNA genome(Meyers et al.,1991;Meyers et al.,2000).Based on an analysis of | Wenkai Liu Ruyi Dang Xinglong Wang | 2015 | Virologica Sinica2015，30，3： | 3 |
| 7 | Crystallization Behavior and Kinetics of Lithium Aluminosilicate Glasses with Various Li_(2)O Contents显示文摘The crystallization behavior of Li_(2)O-Al_(2)O_(3)-SiO_(2) glasses with various concentration of Li2O were investigated by DSC,XRD,and FE-SEM.The h/l-quartz s.s.is the main crystalline phase for all of the glass with the heat treatment of 720℃/3 h+800℃/1.5 h while the crystallinity and crystal size increase with the increase of Li2O contents.Due to the negative thermal expansion coefficient of h/l-quartz s.s.,the thermal expansion coefficient of glass-ceramics decreases with the increasing of Li2O contents.When the Li2O content is 9mol%,the near-zero CTE20-700℃=-0.09×10^(-6)℃^(-1) is obtained upon the heat treatment of 720℃/3 h+800℃/1.5 h.The crystallization activation energy of the glass with 9mol%Li2O is about 351 kJ/mol,and the crystallization mechanism is volume crystallization. | 韩建军 HONG Wei 姜宏 HE Jianxiong WANG Qianchen WANG Jing GAO Wenkai | 2021 | Journal of Wuhan University of Technology(Materials Science)2021，36，2： | 3 |
| 8 | Density functional theory for adsorption of HCHO on the FeO(100) surface显示文摘The density functional theory (DFT) and periodic slab model were used to get information concerning the adsorption of HCHO on the FeO(100) surface. A preferred η2-(C,O)-di-σ four-membered ring adsorption conformation on the Fe-top site was found to be the most favorable structure with the predicted adsorption energy of 210.7 kJ/mol. The analysis of density of states, Mulliken population, and vibrational frequencies before and after adsorption showed clear weakening of the carbonyl bond, and high sp3 character on the carbon atom. | Lingling Wang, Wenkai Chen Department of Chemistry, Fuzhou University, Fuzhou 350108, Fujian, China | 2010 | Journal of Natural Gas Chemistry2010，19，1： | 3 |
| 9 | Large Room-Temperature Magnetoresistance in van der Waals Ferromagnet/Semiconductor Junctions显示文摘A magnetic tunnel junction(MTJ)is the core component in memory technologies,such as the magnetic random-access memory,magnetic sensors and programmable logic devices.In particular,MTJs based on twodimensional van der Waals(vd W)heterostructures offer unprecedented opportunities for low power consumption and miniaturization of spintronic devices.However,their operation at room temperature remains a challenge.Here,we report a large tunnel magnetoresistance(TMR)of up to 85%at room temperature(T=300 K)in vdW MTJs based on a thin(<10 nm)semiconductor spacer WSe_(2)layer embedded between two Fe_(3)GaTe_(2e)lectrodes with intrinsic above-room-temperature ferromagnetism.The TMR in the MTJ increases with decreasing temperature up to 164%at T=10 K.The demonstration of TMR in ultra-thin MTJs at room temperature opens a realistic and promising route for next-generation spintronic applications beyond the current state of the art. | Wenkai Zhu Shihong Xie Hailong Lin Gaojie Zhang Hao Wu Tiangui Hu Ziao Wang Xiaomin Zhang Jiahan Xu Yujing Wang Yuanhui Zheng Faguang Yan Jing Zhang Lixia Zhao Amalia Patanè Jia Zhang Haixin Chang Kaiyou Wang | 2022 | Chinese Physics Letters2022，39，12： | 2 |
| 10 | The chromosome-level reference genome of Coptis chinensis provides insights into genomic evolution and berberine biosynthesis显示文摘Coptis chinensis Franch, a perennial herb, is mainly distributed in southeastern China. The rhizome of C. chinensis hasbeen used as a traditional medicine for more than 2000 years in China and many other Asian countries. Thepharmacological activities of C. chinensis have been validated by research. Here, we present a de novo high-qualitygenome of C. chinensis with a chromosome-level genome of ~958.20 Mb, a contig N50 of 1.58 Mb, and a scaffold N50of 4.53 Mb. We found that the relatively large genome size of C. chinensis was caused by the amplification of longterminal repeat (LTR) retrotransposons. In addition, a whole-genome duplication event in ancestral Ranunculales wasdiscovered. Comparative genomic analysis revealed that the tyrosine decarboxylase (TYDC) and (S)-norcoclaurinesynthase (NCS) genes were expanded and that the aspartate aminotransferase gene (ASP5) was positively selected inthe berberine metabolic pathway. Expression level and HPLC analyses showed that the berberine content was highestin the roots of C. chinensis in the third and fourth years. The chromosome-level reference genome of C. chinensisprovides important genomic data for molecular-assisted breeding and active ingredient biosynthesis. | Da-xia Chen Yuan Pan Yu Wang Yan-Ze Cui Ying-Jun Zhang Rang-yu Mo Xiao-li Wu Jun Tan Jian Zhang Lian-an Guo Xiao Zhao Wenkai Jiang Tian-lin Sun Xiao-Di Hu Long-yun Li | 2021 | Horticulture Research2021，8，1： | 2 |
| 11 | Estimating Seismic Intensity Maps of the 2021 Mw 7.3 Madoi,Qinghai and Mw 6.1 Yangbi,Yunnan,China Earthquakes显示文摘This study focuses on rapidly determining seismic intensity maps of earthquakes because it offers fundamental information for effective emergency rescue and subsequent scientific research,and remains challenging to accurately determine seismic intensity map in regions with sparse instrumental observations.Here we applied a novel method that consisted of array technology(backprojection),ground-motion prediction equations,and site corrections,to estimate the seismic intensity maps of the 2021 Mw 7.3 Madoi,Qinghai and the Mw 6.1 Yangbi,Yunnan,China earthquakes.We used seismic data recorded at European stations to back-project the source processes of the 2021 Mw7.3 Madoi,Qinghai and the Mw 6.1 Yangbi,Yunnan,China earthquakes.The back-projected energy radiations were then used as subevents or used to define the fault geometry.Summing the contributions of each subevent or estimating the shortest distances from each site to the rupture fault,we obtained the ground motion(PGA and PGV)for each site under rock site conditions.The estimated ground motions were corrected at each site for local site amplification according to the Vs30 database.Our estimated seismic intensity maps and field reports showed high similarity,which further validated the effectiveness of the novel approach,and pushed the limit of earthquake size down to~M 6.Such efforts would substantially help in the fast and accurate evaluation of earthquake damage,and precise rescue efforts. | Wenkai Chen Dun Wang Can Zhang Qiang Yao Hongjun Si | 2022 | Journal of Earth Science2022，33，4： | 2 |
| 12 | Efficacy of Danggui Buxue decoction(当归补血汤)on diabetic nephropathy-induced renal fibrosis in rats and possible mechanism显示文摘OBJECTIVE:To observe the efficacy of Danggui Buxue decoction(当归补血汤,DBD) on diabetic nephropathyinduced renal fibrosis in rats,and to study the possible mechanism.METHODS:Sixty male Goto Kakizaki(GK) rats were randomly assigned to the model group,gliquidone group,astragaloside Ⅳ group,and high-,medium-and lowdoses DBD groups.After 8 weeks,changes in body weight,blood glucose,serum creatinine,serum urea nitrogen,and total cholesterol were observed.Changes in transforming growth factor-β1(TGF-β1),Smad3,and Smad5 pathways and the expression of the fibrosisrelated proteins collagen Ⅳ(col Ⅳ),α-smooth muscle actin(α-SMA),and vimentin were assessed.The degree of renal fibrosis was observed by immunohistochemistry and Mason staining.The expression of interleukin 6(IL-6),interleukin 10(IL-10),tumor necrosis factor(TNF-α),and C-reactive protein(CRP) in the kidneys was assessed using enzyme linked immunosorbent assay.RESULTS:Our experiments showed that DBD effectively reduced blood glucose,blood urea nitrogen,and creatinine levels after 8 weeks of administration,improved renal function in diabetic rats,alleviated renal fibrosis,and reduced the renal tissue levels of IL-6,IL-10,TNF-α,and CRP.Furthermore,DBD decreased the expression of TGF-β1,Smad3,col IV,α-SMA,and vimentin in renal tissues and increased the expression of Smad5.CONCLUSIONS:DBD ameliorates diabetic renal interstitial fibrosis by modulating the TGF-β1/Smads pathway. | ZHAO Ye WANG Xian GU Ling LI Zihang ZHU Jingtian WANG Wenkai ZHANG Liang XUE Mei | 2023 | Journal of Traditional Chinese Medicine2023，43，3： | 2 |
| 13 | 13.4 fs,0.1 Hz OPCPA Front End for the 100 PW-Class Laser Facility显示文摘Here,we report the recent progress on the front end developed for the 100 PW-class laser facility.Using 3 stages of optical parametric chirped-pulse amplification(OPCPA)based on lithium triborate(LBO)crystals,we realized a 5.26 J/0.1 Hz amplified output with a bandwidth over 200 nm near the center wavelength of 925 nm.After the compressor,we obtained a pulse duration of 13.4 fs.As the compression efficiency reached 67%,this OPCPA front end could potentially support a peak power of 263 TW at a repetition rate of 0.1 Hz.To the best of our knowledge,among all the 100 TW-level OPCPA systems,it shows the widest spectral width,the shortest pulse duration,and it is also the first OPCPA system working at a repetition-rate mode. | Xinliang Wang Xingyan Liu Xiaoming Lu Junchi Chen Yingbin Long Wenkai Li Haidong Chen Xun Chen Peile Bai Yanyan Li Yujie Peng Yanqi Liu Fenxiang Wu Cheng Wang Zhaoyang Li Yi Xu Xiaoyan Liang Yuxin Leng Ruxin Li | 2022 | Ultrafast Science2022，，3： | 1 |
| 14 | Trace water triggers high-efficiency photocatalytic hydrogen peroxide production显示文摘Photocatalytic production of hydrogen peroxide(H_(2)O_(2))has attracted much attentions as a promising method for sustainable solar fuel.Here,we demonstrate that trace water can drastically boost highefficiency photocatalytic production of H_(2)O_(2) with a record-high concentration of 113 mmol L^(-1) using alkali-assisted C_(3)N_(4) as photocatalyst in water/alcohol mixture solvents.By electron paramagnetic resonance(EPR)measurement,the radical species generated during the photocatalytic process of H_(2)O_(2) are identified.We propose alcohol is used to provide and stabilize-OOH radicals through hydrogen bond,while trace water could trigger photocatalytic production of H_(2)O_(2) via providing and transferring indispensable free protons to completely consume OOH radicals,which breaks the reaction balance of-OOH radical generation from alcohol.Thus-OOH radicals could be supplied by alcohol continuously to serve as a reservoir for high-efficiency production of H_(2)O_(2).These results pave the way towards photocatalytic method on semiconductor catalysts as an outstanding approach for production of hydrogen peroxide. | Zaixiang Xu Yang Li Yongyong Cao Renfeng Du Zhikang Bao Shijie Zhang Fangjun Shao Wenkai Ji jun Yang Guilin Zhuang Shengwei Deng Zhongzhe Wei Zihao Yao Xing Zhong Jianguo Wang | 2022 | Journal of Energy Chemistry2022，31，1： | 1 |

| 16 | Motivation of Parent-Child Co-residence Behavior:Evidenee from the China Health and Retirement Longitudinal Study显示文摘This paper examines the motivations of parent-child co-residence behavior in China using data from the China Health and Retirement Longitudinal Study.We test three possible motives:social norms,self-interest and altruism.We find that social norms play an important role in household co-residence behavior,showing that the belief that'sons take care of parents'is strong,and children in different birth orders take different responsibilities.Taking the one-child policy as a natural experiment,we compared co-residence behavior between only-child and multi-child families.This allowed us to test whether children in multi-child families with wealthier parents more often coreside in order to compete for a bequest.We find that parents'wealth is more appealing to children in multi-child families.The results support the life cycle theory that coresidence decisions are motivated by self-interest.We also find some evidence of altruism when parents and children make co-residence decisions.These findings provide some insights for designing future elder-support policies in China. | Yijie Wang Wenkai Sun Xianghong Wang | 2019 | China & World Economy2019，27，2： | 1 |
| 17 | Land cover classification in a mixed forest-grassland ecosystem using LResU-net and UAV imagery显示文摘Using an unmanned aerial vehicle (UAV) paired with image semantic segmentation to classify land cover within natural vegetation can promote the development of forest and grassland field. Semantic segmentation normally excels in medical and building classification, but its usefulness in mixed forest-grassland ecosystems in semi-arid to semi-humid climates is unknown. This study proposes a new semantic segmentation network of LResU-net in which residual convolution unit (RCU) and loop convolution unit (LCU) are added to the U-net framework to classify images of different land covers generated by UAV high resolution. The selected model enhanced classification accuracy by increasing gradient mapping via RCU and modifying the size of convolution layers via LCU as well as reducing convolution kernels. To achieve this objective, a group of orthophotos were taken at an altitude of 260 m for testing in a natural forest-grassland ecosystem of Keyouqianqi, Inner Mongolia, China, and compared the results with those of three other network models (U-net, ResU-net and LU-net). The results show that both the highest kappa coefficient (0.86) and the highest overall accuracy (93.7%) resulted from LResU-net, and the value of most land covers provided by the producer’s and user’s accuracy generated in LResU-net exceeded 0.85. The pixel-area ratio approach was used to calculate the real areas of 10 different land covers where grasslands were 67.3%. The analysis of the effect of RCU and LCU on the model training performance indicates that the time of each epoch was shortened from U-net (358 s) to LResU-net (282 s). In addition, in order to classify areas that are not distinguishable, unclassified areas were defined and their impact on classification. LResU-net generated significantly more accurate results than the other three models and was regarded as the most appropriate approach to classify land cover in mixed forest-grassland ecosystems. | Chong Zhang Li Zhang Bessie Y.J.Zhang Jingqian Sun Shikui Dong Xueyan Wang Yaxin Li Jian Xu Wenkai Chu Yanwei Dong Pei Wang | 2022 | Journal of Forestry Research2022，33，3： | 1 |
| 18 | Review on status of groundwater database and application prospect in deep-time digital earth plan显示文摘Groundwater is an important water resource.The total amount of active groundwater in a hydrological cycle is about 3.5 times that of the total amount of surface water.The information in the deep groundwater records the material exchange and dynamics in the earth’s evolution,which is an important aspect of the Deep-Time Digital Earth(DDE)plan.In recent years,scientists have discussed the distribution of transboundary aquifers and the environmental significance of groundwater resources through groundwater databases established by international organizations,such as the Global Groundwater Information System and the chronicles consortium,and national institutes,such as national geological surveys.The application of the groundwater database in the DDE plan,however,has been limited by the management,interactivity,and monitoring method of the groundwater data.The ability to further integrate data that are private and scattered across research institutions and individuals,while establishing an open,unified,and shared groundwater data platform,is essential to enhance our understanding of groundwater,ranging from shallow to deep water,which is a goal of the DDE plan.In this study,we introduced the current situation of groundwater database operations in domestic and international research and provided frontier research with groundwater big data.Considering the related objectives of the DDE plan and the limitations of existing groundwater databases,we proposed an improvement plan and new prospects for applying groundwater databases in the research of the deep earth. | Wenkai Qiu Teng Ma Yanxin Wang Jianmei Cheng Chunli Su Junxia Li | 2022 | Geoscience Frontiers2022，13，4： | 1 |
| 19 | Discrepancy between Registered and Actual Unemployment Rates in China:An Investigation in Provincial Capital Cities显示文摘The unemployment rate is a key indicator of labor market and economic performance.Based on a unique survey,we estimate the unemployment rate at 13.44 percent in 30 provincial capital cities in China in 2007,which is well above the officially announced registered unemployment rate.The discrepancy results from inaccuracy in the calculation of registered unemployment.The discrepancy is not stably evolving across regions or over the years,making it difficult to recover the true unemployment rate using a simple multiplier approach.We further investigate the sources of the discrepancy by examining the determinants of unemployment registration.It is evident that participation in certain public activities,which would facilitate the spread of knowledge related to job-searching and unemployment registration,encouraged unemployment registration.Social attention to government antiunemployment programs also encouraged unemployment registration.These findings confirm the behavioral hypothesis that incomplete knowledge and limited attention can cause deviation from optimal choice.The policy implications of the findings of the study are discussed. | Xiaoxia Wang Wenkai Sun | 2014 | China & World Economy2014，22，4： | 1 |
