| 1 | Identification of a Stable Quantitative Trait Locus for Percentage Grains with White Chalkiness in Rice (Oryza sativa)显示文摘High chalkiness is a major problem in many rice-producing areas of the world, especially in hybrid rice (Oryza sativa L.) in China. We previously showed a major quantitative trait locus for the percentage of grains with white chalkiness (QTLqPGWC-8) in the interval G1149-R727 on chromosome 8 using a chromosome segment substitution line (CSSL). Here, we selected the line-CSSL50 harboring the QTLqPGWC-8 allele from the CSSLs derived from a cross between Asominori (as a recurrent parent) and IR24 (as a donor parent), which had higher percentage chalkiness, markedly different from that of Asominori. There were also significant differences in starch granules, appearance of amylose content (AAC) and milling qualities between Asominori and CSSL50, but not in grain size or thousand grain weight (TGW). The BC4F2 and BC4F3 populations from a cross between CSSL50 and Asominori were used for fine mapping of qPGWC-8. We narrowed down the location of this QTL to a 142 kb region between Indel markers 8G-7 and 8G-9. QTLqPGWC-8 accounted for 50.9% of the difference in PGWC between the parents. The markers tightly linked to qPGWC-8 should facilitate cloning of the gene underlying this QTL and will be of value for marker-assisted selection in breeding rice varieties with better grain quality. | Tao Guo Xiaolu Liu Xiangyuan Wan Jianfeng Weng Shijia Liu Xi Liu Mingjiang Chen Jingjing Li Ning Su Fuqing Wu Zhijun Cheng Xiuping Guo Cailin Lei Jiulin Wang Ling jiang Jianmin Wan | 2011 | Journal of Integrative Plant Biology2011，53，8： | 25 |
| 2 | Absorption of Sulphur Dioxide with Sodium Citrate Buffer Solution in a Rotating Packed Bed显示文摘Absorption of SO2 from a SO2/air mixture with sodium citrate buffer solution was investigated using a rotating packed bed(RPB) in laboratory scale.The effects of operating parameters,such as the rotation speed of RPB,liquid-gas ratio,inlet gas flow rate,inlet concentration of SO2 in flue gas,sodium citrate buffer concentration and initial pH of absorption solution,on the SO2 concentration in the absorption solution or removal efficiency of SO2 were examined.Incremental rate of sulfate radical ions in the absorption solution was also examined.Experimental results indicate that the efficiency of this regenerative process will be improved by using RPB under appropriate operating conditions,and the generation of SO2-4 will be restrained in the process in RPB. | JIANG Xiuping LIU Youzhi GU Meiduo | 2011 | Chinese Journal of Chemical Engineering2011，19，4： | 24 |

| 5 | A cyclic nucleotide-gated channel mediates cytoplasmic calcium elevation and disease resistance in rice显示文摘The transient elevation of cytoplasmic calcium is essential for pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI).However,the calcium channels responsible for this process have remained unknown.Here,we show that rice CDSI(CELL DEATH and SUSCEPTIBLE to BLAST 1)encoding OsCNGC9;a cyclic nucleotide-gated channel protein,positively regulates the resistance to rice blast disease.We show that OsCNGC9 mediates PAMP-induced Ca2+influx and that this event is critical for PAMPs-triggered ROS burst and induction of PTI-related defense gene expression.We further show that a PTI related receptor-lih cytoplasmic kinase OsRLCK185 physically interacts with and phosphorylates OsCNGC9 to activate its channel activity.Our results suggest a signaling cascade linking pattern recognition to calcium channel activation,which is required for initiation of PTI and disease resistance in rice. | Jiachang Wang Xi Liu An Zhang Yulong Ren Fuqing Wu Gang Wang Yang Xu Cailin Lei Shanshan Zhu Tian Pan Yongfei Wang Huan Zhang Fan Wang Yan-Qiu Tan Yupeng Wang Xin Jin Sheng Luo Chunlei Zhou Xiao Zhang Jinling Liu Shuai Wang Lingzhi Meng Yihua Wang Xi Chen Qibing Lin Xin Zhang Xiuping Guo Zhijun Cheng Jiulin Wang Yunlu Tian Shijia Liu Ling Jiang Chuanyin Wu Ertao Wang Jian-Min Zhou Yong-Fei Wang Haiyang Wang Jianmin Wan | 2019 | Cell Research2019，29，10： | 13 |
| 6 | Transcriptional activation and phosphorylation of OsCNGC9 confer enhanced chilling tolerance in rice显示文摘Low temperature is a major environmental factor that limits plant growth and productivity.Although transient elevation of cytoplasmic calcium has long been recognized as a critical signal for plant cold tolerance,the calcium channels responsible for this process have remained largely elusive.Here we report that OsCNGC9,a cyclic nucleotide-gated channel,positively regulates chilling tolerance by mediating cytoplasmic calcium elevation in rice(Oryza sativa).We showed that the loss-of-function mutant of OsCNGC9 is defective in cold-induced calcium influx and more sensitive to prolonged cold treatment,whereas OsCNGC9 overexpression confers enhanced cold tolerance.Mechanistically,we demonstrated that in response to chilling stress,OsSAPK8,a homolog of Arabidopsis thaliana OST1,phosphorylates and activates OsCNGC9 to trigger Ca2+influx.Moreover,we found that the transcription of OsCNGC9 is activated by a rice dehydration-responsive element-binding transcription factor,OsDREB1A.Taken together,our results suggest that OsCNGC9 enhances chilling tolerance in rice through regulating cold-induced calcium influx and cytoplasmic calcium elevation. | Jiachang Wang Yulong Ren Xi Liu Sheng Luo Xiao Zhang Xin Liu Qibing Lin Shanshan Zhu Hua Wan Yang Yang Yu Zhang Bin Lei Chunlei Zhou Tian Pan Yongfei Wang Mingming Wu Ruonan jing Yang Xu Meng Han Fuqing Wu Cailin Lei Xiuping Guo Zhijun Cheng Xiaoming Zheng Yihua Wang Zhigang Zhao Ling Jiang Xin Zhang Yong-Fei Wang Haiyang Wang Jianmin Wan | 2021 | Molecular Plant2021，14，2： | 10 |
| 7 | GW5-Like, a homolog of GW5, negatively regulates grain width, weight and salt resistance in rice显示文摘Grain size is an important determinant of yield potential in crops. We previously demonstrated that natural mutations in the regulatory sequences of qSW5/GW5 confer grain width diversity in rice. However, the biological function of a GW5 homolog, named GW5-Like(GW5 L), remains unknown. In this study, we report on GW5 L knockout mutants in Kitaake, a japonica cultivar(cv.)considered to have a weak gw5 variant allele that confers shorter and wider grains. GW5 L is evenly expressed in various tissues, and its protein product is localized to the plasma membrane. Biochemical assays verified that GW5 L functions in a similar fashion to GW5. It positively regulates brassinosteroid(BR) signaling through repression of the phosphorylation activity of GSK2. Genetic data show that GW5 L overexpression in either Kitaake or a GW5 knockout line, Kasaorf3(indica cv. Kasalath background), causes more slender, longer grains relative to the wild-type. We also show that GW5 L could confer salt stress resistance through an association with calmodulin protein OsCa M1-1. These findings identify GW5 L as a negative regulator of both grain size and salt stress tolerance, and provide a potential target for breeders to improve grain yield and salt stress resistance in rice. | Peng Tian Jiafan Liu Changling Mou Cuilan Shi Huan Zhang Zhichao Zhao Qibing Lin Jie Wang Jiulin Wang Xin Zhang Xiuping Guo Zhijun Cheng Shanshan Zhu Yulong Ren Cailin Lei Haiyang Wang Jianmin Wan | 2019 | Journal of Integrative Plant Biology2019，61，11： | 9 |
| 8 | The wheat MYB-related transcription factor TaMYB72 promotes flowering in rice显示文摘Through large-scale transformation analyses, Ta MYB72 was identified as a flowering time regulator in wheat. Ta MYB72 is a MYB family transcription factor localized to the nucleus. Three Ta MYB72 homologs,Ta MYB72-A, Ta MYB72-B and Ta MYB72-D, cloned from hexaploid wheat were mapped to the short arm of the group 6 chromosomes. Under the long-day conditions,over-expression of the Ta MYB72 in rice shortened the flowering time by approximately 12 d. Expression analyses suggest that Ta MYB72 may function through upregulation of florigen genes Hd3 a and RFT1. | Lichao Zhang Guoxiang Liu Jizeng Jia Guangyao Zhao Chuan Xia Lina Zhang Fu Li Qiang Zhang Chunhao Dong Shuangcheng Gao Longzhi Han Xiuping Guo Xin Zhang Jinxia Wu Xu Liu Xiuying Kong | 2016 | Journal of Integrative Plant Biology2016，58，8： | 8 |

| 10 | Change of Soil Organic Carbon after Cropland Afforestation in ′Beijing-Tianjin Sandstorm Source Control′ Program Area in China显示文摘Land use change is one of the major factors that affect soil organic carbon(SOC) variation and global carbon balance. However, the effects of land use change on SOC are always variable. In this study, using a series of paired-field experiments, we estimated the effects of revegetation types and environmental conditions on SOC stock and vertical distribution after replacement of cropland with poplar(Populus tomentosa) and korshinsk peashrub(Caragana korshinskii) in three climate regions(Chifeng City, Fengning City and Datong City of the ′Beijing-Tianjin Sandstorm Source Control′(BTSSC) program area. The results show that SOC sequestration rate ranges from 0.15 Mg/(ha·yr) to 3.76 Mg/(ha·yr) in the soil layer of 0–100 cm in early stage after cropland afforestation in the BTSSC program area. The SOC accumulation rates are the highest in Fengning for both the two vegetation types. Compared to C. korshinskii, P. tomentosa has greater effects on SOC accumulation in the three climate regions, but significantly greater effect only appears in Datong. The SOC density increases by 20%–111% and 15%–59% for P. tomentosa and 9%–63% and 0–73% for C. korshinskii in the 0–20 cm and 20–100 cm soil layers, respectively. Our results indicate that cropland afforestation not only affects SOC stock in the topsoil, but also has some effects on subsoil carbon. However, the effect of cropland afforestation on SOC accumulation varied with climate regions and revegetation types. Considering the large area of revegetation and relatively high SOC accumulation rate, SOC sequestration in the BTSSC program should contribute significantly to decrease the CO2 concentration in the atmosphere. | ZENG Xinhua ZHANG Wanjun LIU Xiuping CAO Jiansheng SHEN Huitao ZHAO Xin ZHANG Nan-nan BAI Yuru Yi Mei | 2014 | Chinese Geographical Science2014，24，4： | 6 |
| 11 | Multimodal hyperspectral remote sensing:an overview and perspective显示文摘Since the advent of hyperspectral remote sensing in the 1980 s,it has made important achievements in aerospace and aviation field and been applied in many fields.Conventional hyperspectral imaging spectrometer extends the number of spectral bands to dozens or hundreds,and provides spatial distribution of the reflected solar radiation from the scene of observation at the same time.Nowadays,with the fast development of new technology in the fields of information and photoelectricity sensing,and the popularity of unmanned aerial vehicle,hyperspectral remote sensing imaging presents the new trends of multimodality and acquires integration information while keeping high or very-high spectral resolution,especially,high temporal even real time sensing and stereo sensing.Therefore,three important modes of hyperspectral imaging come into existence:(1)multitemporal hyperspectral imaging,which refers to the observation of same region at different dates;(2)hyperspectral video imaging,which captures full frame spectral images in real-time;(3)hyperspectral stereo imaging,which obtains the full dimension information(including 2D image,elevation,and spectra)of observed scene.Along this perspective,firstly,the current researches on hyperspectral remote sensing and image processing are briefly reviewed,and then,comprehensive descriptions of the aforementioned three main hyperspectral imaging modes are carried out from the following four aspects:fundamental principle of new mode of hyperspectral imaging,corresponding scientific data acquisition,data processing and application,and potential challenges in data representation,feature learning and interpretation.Through the analysis of development trend of hyperspectral imaging and current research situation,we hope to provide a direction for future research on multimodal hyperspectral remote sensing. | Yanfeng GU Tianzhu LIU Guoming GAO Guangbo REN Yi MA Jocelyn CHANUSSOT Xiuping JIA | 2021 | Science China(Information Sciences)2021，64，2： | 6 |
| 12 | Research and Evaluation on Key Technological Indicators for Airborne and Shipborne Gravimetry显示文摘Gravimetry technical guides are the scientific basis for air-sea gravimetry. However, the existing technical guides in China are behind the application requirements. This study analyzed the most important indicators of air-sea gravimetry, including the density of survey lines, gravimetry accuracy and space resolution, stability and reliability of the air-sea gravimeter, and proposed a gravimetry accuracy assessment system consisting of gravity RMS of error, systematic error and mean error, and an assessment system for the gravimeter stability consisting of the relative accuracy of the scale value, monthly zero-drift, RMS of the monthly nonlinear zero-drift variation and the threshold of the monthly nonlinear zero-drift variation. The mathematic models for the measurement point determination in shipborne gravimetry, E tv s correction for airborne gravimetry, platform tilt correction and evaluation air-sea gravimetry were also analyzed and modified. This work will provide technology support for the composition of the military-civil air-sea gravimetry technical guides. | Motao HUANG Kailiang DENG Taiqi WU Xiuping LU Guojun ZHAI Yongzhong OUYANG Xin CHEN Min LIU | 2019 | Journal of Geodesy and Geoinformation Science2019，2，3： | 6 |
| 13 | Development of DArT markers for a linkage map of flue-cured tobacco显示文摘Tobacco(Nicotiana tabacum) is one of the most economically important nonfood crops,and flue-cured tobacco accounts for approximately 80% of world tobacco production.An extremely narrow genetic diversity in the tobacco pool has led to a low efficiency of PCR-based molecular markers(such as AFLP and SSR).Diversity Arrays Technology(DArT) is a high-throughput hybridisation-based marker system that has been developed in many plants including wheat,which,like tobacco,has a complex genome.In this study,we developed a tobacco DArT chip that included 7680 representative sequence tags based on typical tobacco accessions.The 1076 DArT markers of flue-cured tobacco were identified and most(82.1%) of their polymorphism information contents(PICs) were greater than 0.4.An integrated linkage map that included 851 markers(238 DArT and 613 SSR),which is the highest density map of flue-cured tobacco to date,was constructed.This chip-based DArT system provides an alternative in high-throughput marker genotyping for tobacco. | LU XiuPing GUI YiJie XIAO BingGuang LI YongPing TONG ZhiJun LIU Yun BAI XueFei WU WeiRen XIA Ling HUTTNER Eric KILIAN Adrzej FAN LongJiang | 2013 | Chinese Science Bulletin2013，58，6： | 4 |
| 14 | Processing of 3D meshed surfaces using spherical wavelets显示文摘This paper presents an efficient technique for processing of 3D meshed surfaces via spherical wavelets.More specifically,an input 3D mesh is firstly transformed into a spherical vector signal by a fast low distortion spherical parameterization approach based on symmetry analysis of 3D meshes.This signal is then sampled on the sphere with the help of an adaptive sampling scheme.Finally,the sampled signal is transformed into the wavelet domain according to spherical wavelet transform where many 3D mesh processing operations can be implemented such as smoothing,enhancement,compression,and so on.Our main contribution lies in incorporating a fast low distortion spherical parameterization approach and an adaptive sampling scheme into the frame for processing 3D meshed surfaces by spherical wavelets,which can handle surfaces with complex shapes.A number of experimental examples demonstrate that our algorithm is robust and efficient. | Hu Jianping Liu Xiuping WangXiaochao and Xie Qi | 2012 | Computer Aided Drafting,Design and Manufacturing2012，22，1： | 4 |
| 15 | Preparation of one-dimensional nanostructured ZnO显示文摘Rod-like ZnO particles were synthesized via a sol-gel method by adding ethylene diamine(EDA) to the reaction system of Zn(Ac)2·2H2O and H2C2O4·2H2O.The crystal phase and morphology of the products were characterized by XRD(X-ray powder diffractometer) and TEM(transmission electron microscope).Rod-like ZnO belongs to the hexagonal Wurtzite system,with diameters and lengths of about 20-200 nm and 0.2-1.5 m,respectively.Experimental results showed that the morphology of nano-ZnO can be controlled by modulating the quantities of EDA added into the reaction system and that EDA plays an important role in the formation of rod-like ZnO particles.The growth mechanism of the rod-like nanoZnO was briefly discussed.The proposed facile,reproducible,effective and low-cost synthesis promises future large-scale preparation of nanostructured ZnO for application in nanotechnology. | Xiuping Jiang Youzhi Liu Yanyang Gao Xuejun Zhang Lihong Shi | 2010 | Particuology2010，8，4： | 4 |
| 16 | Potential mechanism of Huatan Qushi decoction on improving phlegm-dampness constitution using microRNA array and RT-qPCR targeting on hsa-miR-1237e3p显示文摘Background:Metabolic diseases pose considerable burden on the healthcare system worldwide,indicating the significance of prevention and treatment.In constitution theory of traditional Chinese medicine,phlegm-dampness constitution(PDC)is the common basis of metabolic diseases.In clinical practice,Huatan Qushi(HTQS)decoction targeting on PDC can effectively improve metabolic indicators.However,its underlying biochemical mechanism still remains unclear.Methods:Eight PDC participants received HTQS decoction for three months.Their blood was collected at baseline and 1 and 3 months after intervention started.Related biomedical indicators were detected.High-throughput sequencing and RT-qPCR were used for validation.Due to the missing data,repeated measures with missing values in mixed models were used.Results:After 3-month treatment,HDL-C level increased(P<.001)and FBG,FINS,and HbA1c all showed decreasing trend at different time points(all P<.05).After miRNA high-throughput sequencing,compared with the baseline,differential miRNAs at 1 and 3 months were screened,and target gene prediction and KEGG pathway enrichment analysis were performed.The results displayed that metabolic disease-related pathways mainly included pathways in cancer,PI3K-Akt signaling pathway,etc.Further,RT-qPCR showed that hsa-miR-1237e3p differed statistically(P=.008).Then we validated the target genes of hsa-miR-1237e3p in the“Pathways in Cancer”pathway including SDF1,AC,CRK,and HGF,also known as upstream target genes of PI3K/AKT pathway.The results showed that two indicators of CRK and HGF were in statistical significance(P=.045 and P=.036,respectively).Conclusion:PDC serves as a common basis for various metabolic diseases.Through adjusting PDC,HTQS decoction can improve biomedical indicators including blood glucose,HbA1c,insulin,and HDL-C.The target pathway is“Pathways in cancer”.Specifically,HTQS decoction acts on targets of CRK and HGF by regulating hsa-miR-1237e3p,and probably exerts effects on their downstream PI3K/AKT pathway. | Xiuping Zhang Ji Wang Baoxing Liu Haiqiang Yao Yu Chen Yuqing Yin Xuejing Yang Lingru Li | 2021 | Journal of Traditional Chinese Medical Sciences2021，8，1： | 3 |
| 17 | Carbon Storage Capacity of Different Plantation Types Under Sandstorm Source Control Program in Hebei Province, China显示文摘Afforestation and reforestation are effective and ecological ways of mitigating elevated atmospheric carbon dioxide(CO2) concentration and increasing carbon(C) storage in terrestrial ecosystems. In this study, we measured the above-ground(tree, herbaceous plants and litter) and below-ground(root and soil) C storage in an aspen plantation(Populus davidiana) monoculture(PD), a larch plantation(Larix pincipis-rupprechtii) monoculture(LP), a pine plantation(Pinus tabulaeformis) monoculture(PT), a larch and birch mixed plantation(L. pincipis-rupprechtii and Betula platyphlla mixed)(MLB), and an apricot plantation(Armeniaca sibirica) monoculture(AS) under the Desertification Combating Program in Hebei Province, the northern China. The objective was to assess the effect of afforestation species on ecosystem C pools of different plantation types. Results showed that C storage of LP stand(258.0 Mg/ha) and MLB(163.4 Mg/ha) were significantly higher than the C storage in PD(45.5 Mg/ha), PT(58.9 Mg/ha) and AS(49.4 Mg/ha), respectively. Soil C was the main carbon pool of the ecosystem C storage in the five plantation stands, ranging from 31.4 Mg/ha to 232.5 Mg/ha, which accounted for 69.0%–90.1% of the total ecosystem C storage. The C storage in tree layer was about 5.2%–23.2% of ecosystem C storage. The herbaceous plants and litter layers contained 1.0%–6.0% and 1.5%–3.3% of ecosystem C storage, respectively. Our results suggest that tree species should be incorporated to accurately develop regional C budget of afforestation program, and also imply that substantial differences in ecosystem C stocks among plantation types can facilitate decision making on C management. | SHEN Huitao ZHANG Wanjun YANG Xue LIU Xiuping CAO Jiansheng ZENG Xinhua ZHAO Xin CHEN Xuexun ZHANG Wenxi | 2014 | Chinese Geographical Science2014，24，4： | 3 |
| 18 | Shape matching and retrieval based on multiple feature descriptors显示文摘A lot of 3D shape descriptors for 3D shape retrieval have been presented so far.This paper proposes a new mechanism,which employs several existing global and local 3D shape descriptors as input.With the sparse theory,some descriptors which play the most important role in measuring similarity between query model and the model in the dataset are selected automatically and an affinity matrix is constructed.Spectral clustering method can be implemented to this affinity matrix.Spectral embedding of this affinity matrix can be applied to retrieval,which integrating almost all the advantages of selected descriptors.In order to verify the performance of our approach,we perform experimental comparisons on Princeton Shape Benchmark database.Test results show that our method is a pose-oblivious,efficient and robustness method for either complete or incomplete models. | WANG Weiming LIU Xiuping LIU Ligang | 2013 | Computer Aided Drafting,Design and Manufacturing2013，23，1： | 3 |

| 20 | A survey of HIV infection and related high-risk factors among men who have sex with men in Suzhou,Jiangsu,China显示文摘A cross-sectional study using the snowball sampling method was conducted in May 2008 to investigate human immunodeficiency virus (HIV) infection status and related high risk factors among men who have sex with men (MSM) in Suzhou city of Jiangsu province. The researchers carried out a face-to-face questionnaire interview among MSM, and collected their blood samples to test for HIV and other sexually transmitted diseases (STDs). Among the 280 respondents, 91.1% had homosexual acts in the past 6 months and 87.5% had multiple homosexual partners; 46.4% had heterosexual sex in the past 6 months and 33.1% had multiple heterosexual partners. The rate of continued condom use was 44.3% in homosexual sex in the past 6 months, while the rate in heterosexual sex was 33.9%. Laboratory test results showed that the prevalences of HIV and syphilis were 7.1% (20/280) and 15.0% (42/280), respectively, but no HCV-positive person was found. In the multivariate logistic regression model, subjects with a monthly income of more than RMB $ 1,000 (OR=4.83,95% CI=1.44-16.22), subjects who often went to bars for sexual partners (OR=2.25, 95%CI=1.21-4.20), and subjects who had more than one sexual partner in the past 6 months (OR=0.49, 95%CI=0.25-0.97) and had sex with fixed sexual partners in the past 6 months (OR=0.42, 95%CI=0.25-0.75) were significantly associated with the rate of continued condom use in homosexual sex in the past 6 months. Unprotected sex and multiple sexual partners were more common among MSM in Suzhou city; furthermore, the prevalences of HIV infection and syphilis were relatively high. HIV preventive measures should be designed to address these risk factors and control the spread of HIV among MSM. | Hongling Bai Xiping Huan Weiming Tang Xin Chen Hongjing Yan Xiaoyan Liu Haitao Yang Zhihang Peng Xiuping Zhao Rongbin Yu Hao Yu Feng Chen | 2011 | The Journal of Biomedical Research2011，25，1： | 2 |
