| 1 | First dark matter search results from the PandaX-Ⅰ experiment显示文摘We report on the first dark-matter(DM)search results from PandaX-I,a low threshold dual-phase xenon experiment operating at the China JinPing Underground Laboratory.In the 37-kg liquid xenon target with 17.4 live-days of exposure,no DM particle candidate event was found.This result sets a stringent limit for low-mass DM particles and disfavors the interpretation of previously-reported positive experimental results.The minimum upper limit,3.7×10-44cm2,for the spin-independent isoscalar DM-particle-nucleon scattering cross section is obtained at a DM-particle mass of 49 GeV/c2at 90%confidence level. | XIAO MengJiao XIAO Xiang ZHAO Li CAO XiGuang CHEN Xun CHEN YunHua CUI XiangYi FANG DeQing FU ChangBo GIBONI Karl L.

| 3 | Influence of genotypes and environmental factors on leaf triterpenoid content and growth of Cyclocarya paliurus显示文摘Cyclocarya paliurus, an economically valuable tree species, has traditionally been used as a nutraceutical food or medicine in China. However, limited information is available on its genotype selection and cultivation under a wide range of environmental conditions for growth and targeted health-promoting substances. We studied the effects of genotype and environment, and their interaction on leaf triterpenoid content and tree growth for 12 genotypes of C. paliurus grown at four sites. We quantified the correlation between leaf triterpenoid accumulation and tree growth. The contents of cyclocaric acid B, cyclocarioside I, and arjunolic acid ranged from 0.06 to 3.89, 0 to 3.71, and 0.65 to 8.86 mg g^-1, respectively. Three individual triterpenoids were primarily influenced by genotype (variation ranged from 53.7 to 68.0%), while environment accounted for most of the variation in total triterpenoid content and tree growth (71.3–89.5%). Most tested environmental parameters were significantly correlated to total triterpenoid content, but not to the contents of the individual triterpenoids measured. Growth in tree height and diameter at breast height were significantly negatively correlated with total triterpenoid content but were non-significantly correlated with individual triterpenoid contents. We conclude that genotypic selection, manipulation of environmental conditions, and implementation of appropriate silvicultural operations would be important strategies for increasing the accumulation of health-promoting phytochemicals. | Bo Deng Shengzuo Fang Xulan Shang Xiangxiang Fu Wanxia Yang | 2019 | Journal of Forestry Research2019，30，3： | 7 |
| 4 | Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2. | HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，3： | 6 |
| 5 | Evaluating Common Land Model Energy Fluxes Using FLUXNET Data显示文摘Given the crucial role of land surface processes in global and regional climates, there is a pressing need to test and verify the performance of land surface models via comparisons to observations. In this study, the eddy covariance measurements from 20 FLUXNET sites spanning more than 100 site-years were utilized to evaluate the performance of the Common Land Model(Co LM) over different vegetation types in various climate zones. A decomposition method was employed to separate both the observed and simulated energy fluxes, i.e., the sensible heat flux, latent heat flux, net radiation, and ground heat flux, at three timescales ranging from stepwise(30 min) to monthly. A comparison between the simulations and observations indicated that Co LM produced satisfactory simulations of all four energy fluxes, although the different indexes did not exhibit consistent results among the different fluxes. A strong agreement between the simulations and observations was found for the seasonal cycles at the 20 sites, whereas Co LM underestimated the latent heat flux at the sites with distinct dry and wet seasons, which might be associated with its weakness in simulating soil water during the dry season. Co LM cannot explicitly simulate the midday depression of leaf gas exchange, which may explain why Co LM also has a maximum diurnal bias at noon in the summer. Of the eight selected vegetation types analyzed, Co LM performs best for evergreen broadleaf forests and worst for croplands and wetlands. | Xiangxiang ZHANG Yongjiu DAI Hongzhi CUI Robert E.DICKINSON Siguang ZHU Nan WEI Binyan YAN Hua YUAN Wei SHANGGUAN Lili WANG Wenting FU | 2017 | Advances in Atmospheric Sciences2017，34，9： | 4 |

| 8 | Whole-genome Duplication Reshaped Adaptive Evolution in A Relict Plant Species,Cyclocarya paliurus显示文摘Cyclocarya paliurus is a relict plant species that survived the last glacial period and shows a population expansion recently.Its leaves have been traditionally used to treat obesity and diabetes with the well-known active ingredient cyclocaric acid B.Here,we presented three C.paliurus genomes from two diploids with different flower morphs and one haplotype-resolved tetraploid assembly.Comparative genomic analysis revealed two rounds of recent whole-genome duplication events and identified 691 genes with dosage effects that likely contribute to adaptive evolution through enhanced photosynthesis and increased accumulation of triterpenoids.Resequencing analysis of 45 C.paliurus individuals uncovered two bottlenecks,consistent with the known events of environmental changes,and many selectively swept genes involved in critical biological functions,including plant defense and secondary metabolite biosynthesis.We also proposed the biosynthesis pathway of cyclocaric acid B based on multi-omics data and identified key genes,in particular gibberellinrelated genes,associated with the heterodichogamy in C.paliurus species.Our study sheds light on evolutionary history of C.paliurus and provides genomic resources to study the medicinal herbs. | Yinquan Qu Xulan Shang Ziyan Zeng Yanhao Yu Guoliang Bian Wenling Wang Li Liu Li Tian Shengcheng Zhang Qian Wang Dejin Xie Xuequn Chen Zhenyang Liao Yibin Wang Jian Qin Wanxia Yang Caowen Sun Xiangxiang Fu Xingtan Zhang Shengzuo Fang | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 1 |

| 11 | An improved evaluation of the neutron background in the PandaX-Ⅱ experiment显示文摘In dark matter direct detection experiments,neutron is a serious source of background,which can mimic the dark matter-nucleus scattering signals.In this paper,we present an improved evaluation of the neutron background in the PandaX-II dark matter experiment by a novel approach.Instead of fully relying on the Monte Carlo simulation,the overall neutron background is determined from the neutron-induced high energy signals in the data.In addition,the probability of producing a dark-matter-like background per neutron is evaluated with a complete Monte Carlo generator,where the correlated emission of neutron(s)andγ(s)in the(α,n)reactions and spontaneous fissions is taken into consideration.With this method,the neutron backgrounds in the Run 9(26-ton-day)and Run 10(28-ton-day)data sets of PandaX-II are estimated to be(0.66±0.24)and(0.47±0.25)events,respectively. | QiuHong Wang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui YingJie Fan DeQing Fang ChangBo Fu LiSheng Geng Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo Ke Han ChangDa He Di Huang Yan Huang YanLin Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju YiHui Lai Kun Liang HuaXuan Liu JiangLai Liu WenBo Ma YuGang Ma YaJun Mao Yue Meng Parinya Namwongsa KaiXiang Ni JinHua Ning XuYang Ning XiangXiang Ren ChangSong Shang Lin Si AnDi Tan AnQing Wang HongWei Wang Meng Wang SiGuang Wang XiuLi Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu Jumin Yuan Dan Zhang HongGuang Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，3： | 0 |
| 12 | Constraining self-interacting dark matter with the full dataset of PandaX-II显示文摘Self-interacting dark matter(SIDM)is a leading candidate proposed to solve discrepancies between predictions of the prevailing cold dark matter theory and observations of galaxies.Many SIDM models predict the existence of a light force carrier that mediates strong dark matter self-interactions.If the mediator couples to the standard model particles,it could produce characteristic signals in dark matter direct detection experiments.We report searches for signals of SIDM models with a light mediator using the full dataset of the PandaX-II experiment,basing on a total exposure of 132 tonne-days.No significant excess over background is found,and our likelihood analysis leads to a strong upper limit on the dark matter-nucleon coupling strength.We further combine the PandaX-II constraints and those from observations of the light element abundances in the early universe,and show that direct detection and cosmological probes can provide complementary constraints on dark matter models with a light mediator. | Jijun Yang Abdusalam Abdukerim Wei Chen Xun Chen Yunhua Chen Chen Cheng Xiangyi Cui Yingjie Fan Deqing Fang Changbo Fu Mengting Fu Lisheng Geng Karl Giboni Linhui Gu Xuyuan Guo Ke Han Changda He Shengming He Di Huang Yan Huang Ran Huo Yanlin Huang Zhou Huang Xiangdong Ji Yonglin Ju Shuaijie Li Qing Lin Huaxuan Liu Jianglai Liu Xiaoying Lu Wenbo Ma Yugang Ma Yajun Mao Yue Meng Nasir Shaheed Kaixiang Ni Jinhua Ning Xuyang Ning Xiangxiang Ren Changsong Shang Guofang Shen Lin Si Andi Tan Anqing Wang Hongwei Wang Meng Wang QiuHong Wang Siguang Wang Wei Wang Xiuli Wang Zhou Wang Mengmeng Wu Shiyong Wu Weihao Wu Jingkai Xia Mengjiao Xiao Xiang Xiao Pengwei Xie Binbin Yan Yong Yang Chunxu Yu Hai-Bo Yu Jumin Yuan Ying Yuan Xinning Zeng Dan Zhang Tao Zhang Li Zhao Qibin Zheng Jifang Zhou Ning Zhou Xiaopeng Zhou | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，11： | 0 |
| 13 | Bovine HSD17B8 gene and its relationship with growth and meat quality traits显示文摘17 b-Hydroxysteroid dehydrogenase type 8(HSD17B8) is an important regulator of lipid and steroid metabolism. In the present study, we aimed to assess the effects of HSD17B8 on growth and meat quality traits in cattle. Transcription profile analysis showed that HSD17B8 was primarily expressed in the salpinx, liver, and testis.Meanwhile, we identified three SNPs(SNP1: intron1-A91G; SNP2: exon 1-A90G; and SNP3: intron 8-A86G)of the bovine HSD17B8 gene and investigated its haplotype frequencies and linkage disequilibrium. The detected SNPs were found associated with growth traits(body weight,body length, height at withers, heart girth, hip width, and average daily gain) in native cattle populations(Nanyangand Jiaxian) as well as the meat quality traits(Warner–Bratzler shear force, rib area, dressing percentage, carcass weight, and backfat thickness) in commercial breeds(Angus, Hereford, Limousin, Luxi, Simmental, and Jinnan).Our results provided evidence that polymorphisms in the HSD17B8 gene were associated with growth traits and meat quality traits. Moreover, our findings might be used for marker-assisted selection in beef cattle breeding program. | Yun Ma Ningbo Chen Fen Li Weiwei Fu Yapeng Han Yanlin Chang Xiangxiang Jiang Junya Li Yueyu Bai Xuxin Tan | 2015 | Science Bulletin2015，60，18： | 0 |

| 15 | Rapid Detection of β-lactam Antibiotic Residue in Milk Using Biolayer Interferometry显示文摘[Objective]This study aimed to establish a high-sensitivity method for rapid detection of β-lactam antibiotic residue in milk. [Method]Based on biolayer interferometry technology,ampicillin-BSA conjugate was fixed on the bottom of APS fiber optic biosensor probe through hydrophobic interaction and bound to40 nm colloidal gold-labeled β-lactam antibiotic receptor,to detect β-lactam antibiotics in milk. [Result]The sensitivity of colloidal gold-labeled BLI method was twice as high as that of immunochromatographic test strip in detection of β-lactam antibiotic residue in milk. Colloidal gold-labeled BLI method exhibited good specificity and had no cross-reaction with 1 000 ng/ml aflatoxin M1,gentamicin,kanamycin,streptomycin,tylosin,chloromycetin and melamine. [Conclusion] The colloidal gold-labeled BLI method is not suitable for quantitative detection in actual production due to its small quantitative range in detection of β-lactam antibiotics,but it is a simple and rapid qualitative detection method that can be used in rapid detection of β-lactam antibiotic residue in milk. | Xiaojun LIU Hui FU Feng XUE Tao MA Xiangxiang ZENG Hai ZHU | 2014 | Agricultural Biotechnology2014，3，1： | 0 |
