| 1 | Root microbiota shift in rice correlates with resident time in the field and developmental stage显示文摘Land plants in natural soil form intimate relationships with the diverse root bacterial microbiota. A growing body of evidence shows that these microbes are important for plant growth and health. Root microbiota composition has been widely studied in several model plants and crops; however, little is known about how root microbiota vary throughout the plant's life cycle under field conditions. We performed longitudinal dense sampling in field trials to track the time-series shift of the root microbiota from two representative rice cultivars in two separate locations in China. We found that the rice root microbiota varied dramatically during the vegetative stages and stabilized from the beginning of the reproductive stage, after which the root microbiota underwent relatively minor changes until rice ripening. Notably, both rice genotype and geographical location influenced the patterns of root microbiota shift that occurred during plant growth. The relative abundance of Deltaproteobacteria in roots significantly increased overtime throughout the entire life cycle of rice, while that of Betaproteobacteria, Firmicutes, and Gammaproteobacteria decreased. By a machine learning approach, we identified biomarker taxa and established a model to correlate root microbiota with rice resident time in the field(e.g., Nitrospira accumulated from 5 weeks/tillering in field-grown rice). Our work provides insights into the process of rice root microbiota establishment. | Jingying Zhang Na Zhang Yong-Xin Liu Xiaoning Zhang Bin Hu Yuan Qin Haoran Xu Hui Wang Xiaoxuan Guo Jingmei Qian Wei Wang Pengfan Zhang Tao Jin Chengcai Chu Yang Bai | 2018 | Science China(Life Sciences)2018，61，6： | 24 |

| 4 | Online single particle measurement of fireworks pollution during Chinese New Year in Nanning显示文摘Time-resolved single-particle measurements were conducted during Chinese New Year in Nanning, China. Firework displays resulted in a burst of SO_2, coarse mode, and accumulation mode(100–500 nm) particles. Through single particle mass spectrometry analysis, five different types of particles(fireworks-metal, ash, dust, organic carbon-sulfate(OC-sulfate), biomass burning) with different size distributions were identified as primary emissions from firework displays. The fireworks-related particles accounted for more than70% of the total analyzed particles during severe firework detonations. The formation of secondary particulate sulfate and nitrate during firework events was investigated on single particle level. An increase of sulfite peak(80SO_3^-) followed by an increase of sulfate peaks(97HSO_4^-+ 96SO_4^-) in the mass spectra during firework displays indicated the aqueous uptake and oxidation of SO_2 on particles. High concentration of gaseous SO_2, high relative humidity and high particle loading likely promoted SO_2 oxidation. Secondary nitrate formed through gas-phase oxidation of NO_2 to nitric acid, followed by the condensation into particles as ammonium nitrate. This study shows that under worm, humid conditions, both primary and secondary aerosols contribute to the particulate air pollution during firework displays. | Jingyan Li Tingting Xu Xiaohui Lu Hong Chen Sergey A.Nizkorodov Jianmin Chen Xin Yang Zhaoyu Mo Zhiming Chen Huilin Liu Jingying Mao Guiyun Liang | 2017 | Journal of Environmental Sciences2017，29，3： | 3 |
| 5 | TLR9 agonist enhances radiofrequency ablation-induced CTL responses, leading to the potent inhibition of primary tumor growth and lung metastasis显示文摘Radiofrequency ablation(RFA)is the most common approach to thermal ablation for cancer therapy.Unfortunately,its efficacy is limited by incomplete ablation,and further optimization of RFA is required.Here,we demonstrate that incubation at 65°C triggers more EG7 tumor cell death by necrosis than treatment at 45°C,and the 65°C-treated cells are more effective at inducing antigen-specific CD8^(+)cytotoxic T lymphocyte(CTL)responses after injection in mice than the 45°C-treated ones.Dendritic cells(DCs)that phagocytose 65°C-treated EG7 cells become mature with upregulated MHCII and CD80 expression and are capable of efficiently inducing effector CTLs in mouse tumor models.RFA(65°C)therapy of EG7 tumors induces large areas of tumor necrosis and stimulates CTL responses.This leads to complete regression of small(~100 mm^(3))tumors but fails to suppress the growth of larger(~350 mm^(3))tumors.The administration of the Toll-like receptor-9(TLR9)agonist unmethylated cytosine-phosphorothioate-guanine oligonucleotide(CpG)to DCs phagocytosing 65°C-treated EG7 cells enhances the expression of MHCII and CD40 on DCs as well as DC-induced stimulation of CTL responses.Importantly,the intratumoral administration of CpG following RFA also increases the frequencies of tumor-associated immunogenic CD11b−CD11c^(+)CD103^(+)DC2 and CD11b+F4/80+MHCII+M1 macrophages and increases CD4^(+)and CD8^(+)T-cell tumor infiltration,leading to enhanced CD4^(+)T cell-dependent CTL responses and potent inhibition of primary RFA-treated or distant untreated tumor growth as well as tumor lung metastasis in mice bearing larger tumors.Overall,our data indicate that CpG administration,which enhances RFA-induced CTL responses and ultimately potentiates the inhibition of primary tumor growth and lung metastasis,is a promising strategy for improving RFA treatment,which may assist in optimizing this important cancer therapy. | Aizhang Xu Lifeng Zhang Jingying Yuan Fatma Babikr Andrew Freywald Rajni Chibbar Michael Moser Wenjun Zhang Bing Zhang Zhaoying Fu Jim Xiang | 2019 | Cellular & Molecular Immunology2019，16，10： | 3 |
| 6 | Study on the endogenous phosphorus load of sediments in Miyun reservoir显示文摘Based on the research into the physical-chemical properties and distribution of sediments and the characteristics of pore water in sediments of Miyun reservoir, the release flux of the total phosphorus (TP) from sediments is estimated by simulating deposit environment of reservoir bottom in laboratory. They are 0.018 mg·cm-2·d-1 and 0.821 mg·cm-2·d-1 at 2℃ and 8℃ respectively. The gross TP released in a year is 11.34t. As a contrast, the pore water diffusion simulation method is used to measure gross TP released and gains 11.56t. The two results are relatively close and prove that experiment simulation has some reliability. On the basis of experiments, some conclusions can be drawn: (1) Endogenous phosphorus from sediments accounts for 27.9 percent of the TP entering the reservoir, and it cannot be ignored; and (2) increasing temperature is helpful to TP releasing from sediments. | XU Qing, LIU Xiaoduan, WANG Huifeng, LIU Liu & LIU Jingying National Research Center of Geoanalysis, Beijing 100037, China The Occupational Disease Research Institute of Beijing, Beijing 100020, China College of Maths, Jilin University, Jilin 130026, China | 2005 | Science China Earth Sciences2005，48，z2： | 3 |
| 7 | Analysis of the origin of peak aerosol optical depth in springtime over the Gulf of Tonkin显示文摘By aggregating MODIS(moderate-resolution imaging spectroradiometer) AOD(aerosol optical depth) and OMI(ozone monitoring instrument) UVAI(ultra violet aerosol index)datasets over 2010–2014, it was found that peak aerosol loading in seasonal variation occurred annually in spring over the Gulf of Tonkin(17–23°N, 105–110°E). The vertical structure of the aerosol extinction coefficient retrieved from the spaceborne lidar CALIOP(cloud-aerosol lidar with orthogonal polarization) showed that the springtime peak AOD could be attributed to an abrupt increase in aerosol loading between altitudes of 2 and 5 km.In contrast, aerosol loading in the low atmosphere(below 1 km) was only half of that in winter. Wind fields in the low and high atmosphere exhibited opposite transportation patterns in spring over the Gulf of Tonkin, implying different sources for each level. By comparing the emission inventory of anthropogenic sources with biomass burning, and analyzing the seasonal variation of the vertical structure of aerosols over the Northern Indo-China Peninsula(NIC), it was concluded that biomass burning emissions contributed to high aerosol loading in spring. The relatively high topography and the high surface temperature in spring made planetary boundary layer height greater than 3 km over NIC. In addition, small-scale cumulus convection frequently occurred, facilitating pollutant rising to over 3 km, which was a height favoring long-range transport. Thus, pollutants emitted from biomass burning over NIC in spring were raised to the high atmosphere, then experienced long-range transport, leading to the increase in aerosol loading at high altitudes over the Gulf of Tonkin during spring. | Xiaoli Shan Jun Xu Yixue Li Feng Han Xiaohui Du Jingying Mao Yunbo Chen Youjiang He Fan Meng Xuezhi Dai | 2016 | Journal of Environmental Sciences2016，28，2： | 2 |
| 8 | Formation and emission characteristics of VOCs from a coal-fired power plant显示文摘On-site measurements of volatile organic compounds(VOCs)in different streams of flue gas were carried out on a real coal-fired power plant using sampling bags and SUMMA canisters to collect gas samples,filters to collect particle samples.Gas chromatography-flame ionization detector/mass spectrometry and gas chromatography-mass spectrometry was the offline analysis method.We found that the total mass concentration of the tested 102 VOC species at the outlet of wet flue gas desulfuration device was(13456±47)μg·m^(-3),which contained aliphatic hydrocarbons(57.9%),aromatic hydrocarbons(26.8%),halogen-containing species(14.5%),and a small amount of oxygen-containing and nitrogencontaining species.The most abundant species were 1-hexene,n-hexane and 2-methylpentane.The top ten species in terms of mass fraction(with a total mass fraction of 75.3%)were mainly hydrocarbons with a carbon number of 6 or higher and halogenated hydrocarbons with a lower carbon number.The mass concentration of VOC species in the particle phase was significantly lower than that in the gas phase.The change of VOC mass concentrations along the air pollution control devices indicates that conventional pollutant control equipment had a limited effect on VOC reduction.Ozone formation potential calculations showed that aromatic hydrocarbons contributed the highest ozone formation(46.4%)due to their relatively high mass concentrations and MIR(maximum increment reactivity)values. | Jingying Xu Yue Lyu Jiankun Zhuo Yishu Xu Zijian Zhou Qiang Yao | 2021 | Chinese Journal of Chemical Engineering2021，34，7： | 2 |
| 9 | Plant genome editing using xCas9 with expanded PAM compatibility显示文摘CRISPR/Cas enables robust genome editing and has revolution-ized both functional genomics and crop breeding.The specificity of Cas-directed DNA cleavage is strictly determined by a chimeric single guide RNA(SgRNA)and a short protospacer adjacent motif(PAM)in the genome(Cong et al,2013;Zetsche et al,2015).The widely used Cas9 from Streptococcus pyogenes(SpCas9)generally recognizes the canonical NGG PAM(where N indicates any nucleicacid base)(Miao et al.,2013;Ma et al,2015),making many regionsuntargetable by Cas9.SpCas9 VQR and VRER variants,which recog-nize the non-canonical PAM sequences of NGA and NGCG,respectively,have been used to expand targetable sequences in plants(Hu et al.,2016).In addition,the applications of other Cas endonucleases such as SaCas9(Staphylococcus aureus Cas9)(Ran et al..2015). | Jingying Li Jinman Luo Meilian Xu Shaoya Li Jiahui Zhang Huiyuan Li Lei Yan Yunde Zhao Lanqin Xia | 2019 | Journal of Genetics and Genomics2019，46，5： | 2 |
| 10 | Metallic and ferromagnetic MoS2 nanobelts with vertically aligned edges显示文摘Edge effects are predicted to significantly impact the properties of low dimensional materials with layered structures. The synthesis of low dimensional materials with copious edges is desired for exploring the effects of edges on the band structure and properties of these materials. Here we developed an approach for synthesizing MoS2 nanobelts terminated with vertically aligned edges by sulfurizing hydrothermally synthesized MoO3 nanobelts in the gas phase through a kinetically driven process; we then investigated the electrical and magnetic properties of these metastable materials. These edge-terminated MoS2 nanobelts were found to be metallic and ferromagnetic, and thus dramatically different from the semiconducting and nonmagnetic two-dimensional (2D) and three-dimensional (3D) 2H-MoS2 materials. The transitions in electrical and magnetic properties elucidate the fact that edges can tune the properties of low dimensional materials. The unique structure and properties of this one-dimensional (1D) MoS2 material will enable its applications in electronics, spintronics, and catalysis. | Guanchen Xu Xinsheng Wang Yupeng Sun Xiao Chen Jingying Zheng Lifei Sun Liying Jiao Jinghong Li | 2015 | Nano Research2015，8，9： | 2 |
| 11 | Highly crystalline ReSe2 atomic layers synthesized by chemical vapor transport显示文摘Two-dimensional (2D) anisotropic rhenium diselenide (ReSe2) has attracted lots ofattention due to its promising applications in electronics and optoelectronics. However,controlled synthesis of high quality ultrathin ReSe2 remains as a challenge.Here we developed an approach for synthesizing high quality 2D ReSe2 flakes witha thickness down to monolayer by chemical vapor transport (CVT) through carefullytuning the growth kinetics. The atomic structures and anisotropy of theobtained ReSe2 flakes were intensively characterized with scanning transmissionelectron microscope and angle-resolved polarized Raman spectroscopy. Fieldeffecttransistors fabricated on the CVT-grown ReSe2 flakes showed n-typesemiconducting behavior with an on/off current ratio of 105 and a mobility up to5 cm2 V−1 s−1, which is comparable to mechanically exfoliated flakes and isobvious higher than the samples synthesized with other approaches. This study notonly make high quality 2D ReSe2 easily accessible for both fundamental and applicationexplorations but also sheds new lights on the chemical synthesis of otheranisotropic 2D materials. | Lei Xing Xingxu Yan Jingying Zheng Guanchen Xu Zhixing Lu Lina Liu Jinghui Wang Peng Wang Xiaoqing Pan Liying Jiao | 2019 | InfoMat2019，1，4： | 2 |

| 18 | Plasma-enhanced catalytic activation of CO_(2) in a modified gliding arc reactor显示文摘For the first time,this paper demonstrates a synergistic effect from the combination of a gliding arc discharge plasma with a photocatalyst TiO_(2) for CO_(2) dissociation.The effects of adding a tray downstream the discharge and the combination of the catalyst with plasma have been investigated.Two different combination modes of plasma catalysis,i.e.,in-plasma catalysis and post-plasma catalysis,have been evaluated with the emphasis on the analysis of potential mechanisms.The results show that modifying the gliding arc reactor by the addition of a tray can enhance the fraction of gas treated by plasma,thus improv-ing the reaction performance.An exceptional synergistic effect of combining the gliding arc discharge with TiO_(2) for CO_(2) activation forms in the in-plasma catalysis mode.The presence of TiO_(2) significantly enhances the CO_(2) conversion by 138% and the energy efficiency by 133%at a flow rate of 2 L/min.The plasma activation effect,which produces energetic electrons that can create the electron-hole pairs on the catalyst surface,is believed to be the major contributor to the generation of the plasma catalysis synergy.This mechanism has been further evidenced by the negligible influence of the post-plasma catalysis on the reaction performance. | Hao Zhang Li Li Ruiyang Xu Jingying Huang Ni Wang Xiaodong Li Xin Tu | 2020 | Waste Disposal and Sustainable Energy2020，2，2： | 1 |
