| 4 | Cadmium accumulation and tolerance of two castor cultivars in relation to antioxidant systems显示文摘To investigate the effects of Cd on tolerance and antioxidant activities of castor, two different castor(Ricinus communis L.) cultivars(Zibo No. 5 and Zibo No. 8) were used for a hydroponic experiment(0, 1 and 2 mg/L Cd) and a pot experiment using Cd-contaminated soil(34 mg/kg) with the addition of ethylenedinitrilotetraacetic acid(EDTA). The results indicated that there were significant differences between the two cultivars with respect to Cd uptake in shoots(113–248 mg/kg for Zibo No. 5 and 130–288 mg/kg Zibo No. 8), biomass tolerance indexes(64.9%–74.6% for Zibo No. 5 and 80.1%–90.9% for Zibo No. 8) in the hydroponic experiment and survival rates(0% for Zibo No. 5 and 100% for Zibo No. 8)determined by the addition of EDTA in the pot experiment, suggesting that Zibo No. 8 has higher tolerance than Zibo No. 5. Moreover, the castor cultivars have low bioconcentration factors(4.80% for Zibo No. 5 and 5.43% for Zibo No. 8) and low translocation factors(<1%).Consequently, Zibo No. 8 can participate in Cd phytostabilization in highly Cd-polluted areas. The results indicated that glutathione(GSH) as a non-enzymatic antioxidant, and antioxidant enzymes including superoxide dismutase(SOD), catalase(CAT) and guaiacol peroxidase(GPX), were cultivar- and dose-dependent. The higher tolerance of Zibo No. 8compared with Zibo No. 5 can be attributed to the higher GSH levels in the root and higher GPX activity in the leaf. | Hanzhi Zhang Qingjun Guo Junxing Yang Tongbin Chen Guangxu Zhu Marc Peters Rongfei Wei Liyan Tian Chunyu Wang Deyun Tan Jie Ma Gangming Wang Yingxin Wan | 2014 | Journal of Environmental Sciences2014，26，10： | 15 |
| 5 | RAB31 marks and controls an ESCRT-independent exosome pathway显示文摘Exosomes are generated within the multivesicular endosomes(MVEs)as intraluminal vesicles(ILVs)and secreted during the fusion of MVEs with the cell membrane.The mechanisms of exosome biogenesis remain poorly explored.Here we identify that RAB31 marks and controls an ESCRT-independent exosome pathway.Active RAB31,phosphorylated by epidermal growth factor receptor(EGFR),engages flotillin proteins in lipid raft microdomains to drive EGFR entry into MVEs to form ILVs,which is independent of the ESCRT(endosomal sorting complex required for transport)machinery.Active RAB31 interacts with the SPFH domain and drives ILV formation via the Flotillin domain of flotillin proteins.Meanwhile,RAB31 recruits GTPase-activating protein TBC1D2B to inactivate RAB7,thereby preventing the fusion of MVEs with lysosomes and enabling the secretion of ILVs as exosomes.These findings establish that RAB31 has dual functions in the biogenesis of exosomes:driving ILVs formation and suppressing MVEs degradation,providing an exquisite framework to better understand exosome biogenesis. | Denghui Wei Weixiang Zhan Ying Gao Liyan Huang Run Gong Wen Wang Ruhua Zhang Yuanzhong Wu Song Gao Tiebang Kang | 2021 | Cell Research2021，31，2： | 12 |
| 6 | Fluorination vs. chlorination: a case study on high performance organic photovoltaic materials显示文摘Halogenation is a very efficient chemical modification method to tune the molecular energy levels, absorption spectra and molecular packing of organic semiconductors. Recently, in the field of organic solar cells(OSCs), both fluorine-and chlorinesubstituted photovoltaic materials, including donors and acceptors, demonstrated their great potentials in achieving high power conversion efficiencies(PCEs), raising a question that how to make a decision between fluorination and chlorination when designing materials. Herein, we systemically studied the impact of fluorination and chlorination on the properties of resulting donors(PBDB-T-2 F and PBDB-T-2 Cl) and acceptors(IT-4 F and IT-4 Cl). The results suggest that all the OSCs based on different donor and acceptor combinations can deliver good PCEs around 13%–14%. Chlorination is more effective than fluorination in downshifting the molecular energy levels and broadening the absorption spectra. The influence of chlorination and fluorination on the crystallinity of the resulting materials is dependent on their introduction positions. As chlorination has the advantage of easy synthesis, it is more attractive in designing low-cost photovoltaic materials and therefore may have more potential in largescale applications. | Yun Zhang Huifeng Yao Shaoqing Zhang Yunpeng Qin Jianqi Zhang Liyan Yang Wanning Li Zhixiang Wei Feng Gao Jianhui Hou | 2018 | Science China Chemistry2018，61，10： | 11 |
| 7 | Spatial and Temporal Changes of Arable Land Driven by Urbanization and Ecological Restoration in China显示文摘Since the industrial revolution, human activities have both expanded and intensified across the globe resulting in accelerated land use change. Land use change driven by China’s development has put pressure on the limited arable land resources, which has affected grain production. Competing land use interests are a potential threat to food security in China. Therefore, studying arable land use changes is critical for ensuring future food security and maintaining the sustainable development of arable land. Based on data from several major sources, we analyzed the spatio-temporal differences of arable land among different agricultural regions in China from 2000 to 2010 and identified the drivers of arable land expansion and loss. The results revealed that arable land decreased by 5.92 million ha or 3.31%. Arable land increased in the north and decreased in the south of China. Urbanization and ecological restoration programs were the main drivers of arable land loss, while the reclamation of other land cover types(e.g., forest, grassland, and wetland) was the primary source of the increased arable land. The majority of arable land expansion occurred in the Northwest, but the centroid for grain production moved to northeast, which indicated that new arable land was of poor quality and did not significantly contribute to the grain production capacity. When combined with the current ‘Red Line of Arable Land Policy’(RAL) and ‘Ecological Redline Policy’(EPR), this study can provide effective information for arable land policymaking and help guide the sustainable development of arable land. | WANG Liyan ANNA Herzberger ZHANG Liyun XIAO Yi WANG Yaqing XIAO Yang LIU Jianguo OUYANG Zhiyun | 2019 | Chinese Geographical Science2019，29，5： | 9 |

| 9 | Analysis of genetic architecture and favorable allele usage of agronomic traits in a large collection of Chinese rice accessions显示文摘Genotyping and phenotyping large natural populations provide opportunities for population genomic analysis and genome-wide association studies(GWAS). Several rice populations have been re-sequenced in the past decade;however, many major Chinese rice cultivars were not included in these studies. Here, we report large-scale genomic and phenotypic datasets for a collection mainly comprised of 1,275 rice accessions of widely planted cultivars and parental hybrid rice lines from China. The population was divided into three indica/Xian and three japonica/Geng phylogenetic subgroups that correlate strongly with their geographic or breeding origins. We acquired a total of 146 phenotypic datasets for 29 agronomic traits under multi-environments for different subpopulations. With GWAS, we identified a total of 143 significant association loci, including three newly identified candidate genes or alleles that control heading date or amylose content. Our genotypic analysis of agronomically important genes in the population revealed that many favorable alleles are underused in elite accessions, suggesting they may be used to provide improvements in future breeding efforts. Our study provides useful resources for rice genetics research and breeding. | Xiuxiu Li Zhuo Chen Guomin Zhang Hongwei Lu Peng Qin Ming Qi Ying Yu Bingke Jiao Xianfeng Zhao Qiang Gao Hao Wang Yunyu Wu Juntao Ma Liyan Zhang Yongli Wang Lingwei Deng Shanguo Yao Zhukuang Cheng Diqiu Yu Lihuang Zhu Yongbiao Xue Chengcai Chu Aihong Li Shigui Li Chengzhi Liang | 2020 | Science China(Life Sciences)2020，63，11： | 8 |

| 11 | An individualized immune signature of pretreatment biopsies predicts pathological complete response to neoadjuvant chemoradiotherapy and outcomes in patients with esophageal squamous cell carcinoma显示文摘No clinically available biomarkers can predict pathological complete response(pCR)for esophageal squamous cell carcinomas(ESCCs)with neoadjuvant chemoradiotherapy(nCRT).Considering that antitumor immunity status is an important determinant for nCRT,we performed an integrative analysis of immune-related gene profiles from pretreatment biopsies and constructed the first individualized immune signature for pCR and outcome prediction of ESCCs through a multicenter analysis.During the discovery phase,14 differentially expressed immune-related genes(DEIGs)with greater than a twofold change between pCRs and less than pCRs( | Chaoqi Zhang Guochao Zhang Nan Sun Zhen Zhang Liyan Xue Zhihui Zhang Haijun Yang Yuejun Luo Xiaoli Zheng Yonglei Zhang Yufen Yuan Ruixue Lei Zhaoyang Yang Bo Zheng Le Wang Yun Che Feng Wang Sihui Wang Shugeng Gao Qi Xue Yi Zhang Jie He | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 7 |
| 12 | Cloning,expression and binding specificity analysis of odorant binding protein 3 of the lucerne plant bug,Adelphocoris lineolatus(Goeze)显示文摘Credible evidence shows that odorant binding proteins(OBPs)are required for insect olfaction perception and play a key role in transporting hydrophobic odorants across the sensillum lymph to the olfactory receptors(ORs).In the present study,a novel OBP(AlinOBP3)gene from the lucerne plant bug,Adelphocoris lineolatus,was cloned and expressed.The expression pattern of AlinOBP3 was evaluated by qPCR,which indicated that AlinOBP3 was dominantly expressed in antennae.The binding properties of AlinOBP3 with 9 cotton volatiles and 5 sex pheromone analogs were measured by fluorescence competitive binding assays with the fluorescence probe 1-NPN.The results revealed that of 9 cotton volatiles,Myrcene,β-Ocimene and α-Phellandrene can bind with AlinOBP3.α-Phellandrene especially bound to AlinOBP3 with a high binding affinity,with a dissociation constant of 56.68 μmol/L.Of the 5 sex pheromone analogs,Hexyl butyrate had the strongest binding affinity with AlinOBP3,with a dissociation constant as 59.53 μmol/L.Butyl butyrate,trans-2-Hexenyl butyrate and Ethyl butyrate had medium binding affinities with AlinOBP3,with dissociation constants of 227.39,108.77 and 143.47 μmol/L,respectively.The results suggest that AlinOBP3 might be a pheromone binding protein(PBP)with a dual-function for the perception of sex pheromones and plant volatiles. | GU ShaoHua SUN Yang REN LiYan ZHANG XueYing ZHANG YongJun WU KongMing GUO YuYuan | 2010 | Chinese Science Bulletin2010，55，34： | 7 |
| 13 | Review of CHINARE chemical oceanographic research in the Southern Ocean during 1984–2016显示文摘Between 1984 and 2016, China executed 33 Antarctic cruises with the icebreaker R/V Xuelong, which have provided opportunities for Chinese scientists to investigate the status and changes of the Southern Ocean. Research in chemical oceanography constitutes one of the primary missions of the Chinese National Antarctic Research Expedition(CHINARE). This paper reviews nearly 30 years of Chinese Antarctic expeditions, focusing on the major progress achieved in chemical oceanographic research. Specifically, the sea-surface distributions and air–sea fluxes of CO_2 and N_2O are considered, and the transport, flux, and budget of organic matter are investigated based on isotopes in the Southern Ocean, especially in Prydz Bay. In addition, the nutrient distribution and deep-water particle export in Prydz Bay and the study of aerosol heavy metal characteristics are considered. Finally, the prospects for future Chinese Antarctic chemical oceanographic research are outlined. | CHEN Liqi CHEN Min ZHAN Liyan QI Di GAO Zhongyong WANG Jianjun XU Suqing CHEN Kui ZENG Jian ZHANG Run | 2017 | Advances in Polar Science2017，28，2： | 6 |

| 16 | COR27 and COR28 encode nighttime repressors integrating Arabidopsis circadian clock and cold response显示文摘It was noted that circadian components function in plant adaptation to diurnal temperature cycles and freezing tolerance.Our genome-wide transcriptome analysis revealed that evening-phased COR27 and COR28 mainly repress the transcription of clockassociated evening genes PRR5,ELF4 and cold-responsive genes.Chromatin immunoprecipitation indicated that CCA1 is recruited to the site containing EE elements of COR27 and COR28 promoters in a temperaturedependent way.Further genetic analysis shows COR28 is essential for the circadian function of PRR9 and PRR7.Together,our results support a role of COR27 and COR28 as nighttime repressors integrating circadian clock and plant cold stress responses. | peng wang xuan cui chunsheng zhao liyan shi guowei zhang fenglong sun xiaofeng cao li yuan qiguang xie xiaodong xu | 2017 | Journal of Integrative Plant Biology2017，59，2： | 6 |
| 17 | Tissue engineering using 3D printed nano-bioactive glass loaded with NELL1 gene for repairing alveolar bone defects显示文摘The purposes of this study were to construct a novel tissue engineered bone composed of 3Dprinted bioactive glass block/chitosan nanoparticles(BD/CSn)composites loaded with Nel-like Type I molecular-1 DNA(pDNA-NELL1)and/or bone marrow mesenchymal stem cells(BMSCs),and study their osteogenic activities by repairing bone defects in rhesus monkeys.CSn with NELL1 gene plasmid and rhesus monkey BMSCs were composited with a BD scaffold to prepare the tissue-engineered bone.Four adult female rhesus monkeys with 10-to 12-years old and 5-7 kg in weight were used in animal experiments.The first and second premolar teeth from four regions of each monkey were removed to form bone defects with size of 10×10×5 mm,which were then implanted with above-mentioned tissue engineered bone.At 12 weeks after the implantation,gross observations,X-ray and micro-CT observations revealed that the new bone was extremely close to normal bone in mass,density,hardness,and structure.The bony cortex was smooth and closely connected to the surrounding normal bone.Histological observations revealed moderate inflammation in the repair area,and the new bone tissues were similar to normal ones.In conclusion,tissue engineered bone of this study exhibited good osteoconductivity for promoting the formation of new alveolar bone tissue,and NELL1 gene played a promotional role in bone regeneration. | Jing Zhang Yang Chen Jing Xu Jingjing Wang Chengzhang Li Liyan Wang | 2018 | Regenerative Biomaterials2018，5，4： | 6 |
| 18 | Research and development of new neodymium laser glasses显示文摘This work presents a brief introduction on three kinds of newly developed Nd^(3+)-doped laser glasses in Shanghai Institute of Optics and Fine Mechanics(SIOM), China. Two Nd^(3+)-doped phosphate glasses with lower thermal expansion coefficient and thermal shock resistance 4 times higher than that of N31 glass are developed for laser processing.Nd:Silicate and Nd:Aluminate glasses with peak emission wavelength at 1061 and 1065 nm, effective emission bandwidth of 34 and 50 nm, respectively, are developed for Exawatt-class laser system application. Fluorophosphate glasses with low nonlinear refractive index(n_2=0.6–0.86) and long fluorescence lifetime(430–510 μs) are investigated for the purpose of decreasing B integral in high-power laser system. The properties of all these glasses are presented and compared with those of commercial neodymium laser glasses. | Dongbing He Shuai Kang Liyan Zhang Lin Chen Yajun Ding Qianwen Yin Lili Hu | 2017 | High Power Laser Science and Engineering2017，5，1： | 6 |
| 19 | Analysis of IGF2 mRNA expression and its methylation status between cattle yaks and their parents显示文摘Cattle yaks are an F1 hybrid between cattle and yaks and exhibit significant hybrid vigor. However, cattle yaks are sterile males. To study the epigenetic aspects of this reproductive isolation, IGF2 mRNA expression in cattle yaks and their parents and the patterns of the IGF2 differentially methylated regions (DMR) were examined in blood and testes. The results showed that IGF2 expression in cattle yaks' testes was lower than in their parents (P < 0.01). The IGF2 DMR was highly methylated (above 90%) in blood and testes of cattle yaks, yaks and cattle, with the highest level in cattle yaks (P > 0.05). Our study showed that IGF2 plays an important role in bovine spermato-genesis and might be involved in cattle-yak male sterility. The methylation level of the IGF2 DMR was irrelevant to the lower expression of IGF2 in cattle yaks; other factors perhaps play roles in its expression. | Zhenshan Liu Qifa Li Qingbo Zhang Xuguang Qu Liyan Dong Chamba Yang-zom Zhuang Xie Honglin Liu | 2009 | Progress in Natural Science:Materials International2009，19，9： | 5 |
| 20 | Secalonic acid D induces cell apoptosis in both sensitive and ABCG2-overexpressing multidrug resistant cancer cells through upregulating c-Jun expression显示文摘Secalonic acid D(SAD) could inhibit cell growth in not only sensitive cells but also multidrug resistant(MDR) cells. However, the molecular mechanisms need to be elucidated. Here, we identified that SAD possessed potent cytotoxicity in 3 pairs of MDR and their parental sensitive cells including S1-MI-80 and S1,H460/MX20 and H460, MCF-7/ADR and MCF-7 cells. Furthermore, SAD induced cell G2/M phase arrest via the downregulation of cyclin B1 and the increase of CDC2 phosphorylation. Importantly, JNK pathway upregulated the expression of c-Jun in protein level and increased c-Jun phosphorylation induced by SAD, which was linked to cell apoptosis via c-Jun/Src/STAT3 pathway. To investigate the mechanisms of upregulation of c-Jun protein by SAD, the mR NA expression level and degradation of c-Jun were examined. We found that SAD did not alter the mR NA level of c-Jun but inhibited its proteasome-dependent degradation. Taken together, these results implicate that SAD induces cancer cell death through c-Jun/Src/STAT3 signaling axis by inhibiting the proteasome-dependent degradation of c-Jun in both sensitive cells and ATP-binding cassette transporter sub-family G member 2(ABCG2)-mediated MDR cells. | Hong Zhang Liyan Huang Liyang Tao Jianye Zhang Fang Wang Xu Zhang Liwu Fu | 2019 | Acta Pharmaceutica Sinica B2019，9，3： | 5 |
