| 1 | Temporal and regional variations of China's fertilizer consumption by crops during 1998-2008显示文摘The agricultural and land policies in China are always focused on protecting its food supply and security because of the country's large population and improved diets.The crop production guide 'Take Grain as the Key Link' prompted peasants to plant grain on most of the agricultural land,leading to the majority of fertilizer being used in grain crops for many years in China.This situation has changed dramatically in recent years.Based on data pertaining to provincial crops sown area and fertilizer use per unit area in 1998 and 2008,the temporal and spatial variations of China's fertilizer consumption by crops were analyzed at the provincial level,and the results are presented here.(1) Fertilizer consumption in China grew strongly in the last decade,while the growth was mainly attributable to the increase of fertilizer con-sumption by horticultural crops.The fertilizer consumption of grain crops dropped from 71.0% in 1998 to 57.8% in 2008.Thus,it is concluded that the emphasis of fertilizer consumption is shifting toward horticultural crops.(2) There were marked differences in the growth rates of fertilizer consumption from the regional point of view.The national average growth rate of fertilizer consumption was 31.9% during 1998-2008.The western and northeastern parts of the country came close to the national average,while the eastern part was lower,with an average of 13.0%,and central China was much higher(50.8%).The increase of fertilizer consumption in central and west China was higher than the other zones,which already ac-counted for 77.9% of the national total.Thus,it is concluded that the consumption emphasis of chemical fertilizer shifts toward the central and western regions.(3) The decline of fertilizer consumption by grain crops was largely due to the decrease in sown area compared with the increase by vegetable crops attributable to the enlarging sown area;the increase by orchard crops was affected by both expanding the sown area and fertilizer use per unit area. | XIN Liangjie LI Xiubin TAN Minghong | 2012 | Journal of Geographical Sciences2012，22，4： | 49 |
| 2 | Activation of gibberellin 2-oxidase 6 decreases active gibberellin levels and creates a dominant semi-dwarf phenotype in rice (Oryza sativa L.)显示文摘Gibberellin (GA) 2-oxidase plays a key role in the GA catabolic pathway through 2β-hydroxylation.In the present study,we isolated a CaMV 35S-enhancer activation tagged mutant,H032.This mutant exhibited a dominant dwarf and GA-deficient phenotype,with a final stature that was less than half of its wild-type counterpart.The endogenous bioactive GAs are markedly decreased in the H032 mutant,and application of bioactive GAs (GA3 or GA4) can reverse the dwarf phenotype.The integrated T-DNA was detected 12.8 kb upstream of the OsGA2ox6 in the H032 genome by TAIL-PCR.An increased level of OsGA2ox6 mRNA was detected at a high level in the H032 mutant,which might be due to the enhancer role of the CaMV 35S promoter.RNAi and ectopic expression analysis of OsGA2ox6 indicated that the dwarf trait and the decreased levels of bioactive GAs in the H032 mutant were a result of the up-regulation of the OsGA2ox6 gene.BLASTP analysis revealed that OsGA2ox6 belongs to the class III of GA 2-oxidases,which is a novel type of GA2ox that uses C20-GAs (GA12 and/or GA53) as the substrates.Interestingly,we found that a GA biosynthesis inhibitor,paclobutrazol,positively regulated the OsGA2ox6 gene.Unlike the over-expression of OsGA2ox1,which led to a high rate of seed abortion,the H032 mutant retained normal flowering and seed production.These results indicate that OsGA2ox6 mainly affects plant stature,and the dominant dwarf trait of the H032 mutant can be used as an efficient dwarf resource in rice breeding. | Jian Huang Ding Tang Yi Shen Baoxiang Qin Lilan Hong Aiqing You Ming Li Xin Wang Hengxiu Yu Minghong Gu Zhukuan Cheng | 2010 | Journal of Genetics and Genomics2010，37，1： | 36 |
| 3 | Urban land expansion and arable land loss of the major cities in China in the 1990s显示文摘Based on the land-use data in 1990 and 2000, determined by interpreting Landsat Thematic Mapper (TM) imagery, this paper defines the extent of urban construction land, and extracts patches of urban construction land of 145 cities with the largest areas in 1990 and arable land patches around these cities. With these data, this paper analyzes the characteristics of ur- ban construction land expansion and the consequent arable land loss in East, Middle and West China, and further identifies the social, economic and spatial factors of the urban land use changes, using GIS (Geographical Information System) and multivariate regression approaches. The results show that total urban land of the 145 cities expanded by 39.8%, with about 70% of the new urban land converted from arable land in the 1990s. The urban land expansion varied among the three regions, with a value of 43.0% in the East, 33.1% in the West (33.1%) and 17.8% in the Middle. Moreover, mean urban construction land per capita increased by10.7% in the East, but it decreased by 7.7% in the Middle, 1.4% in the West. Statistical analysis indicated that total wages of staff and workers could best explain the differences of urban land expansion. | TAN Minghong LI Xiubin LU Changhe | 2005 | Science China Earth Sciences2005，48，9： | 32 |
| 4 | One-dimensional numerical simulation of non-uniform sediment transport under unsteady flows显示文摘One-dimensional numerical models are popularly used in sediment transport research because they can be easily programmed and cost less time compared with two-and three-dimensional numerical models.In particular,they possess greater capacity to be applied in large river basins with many tributaries.This paper presents a one-dimensional numerical model capable of calculating total-load sediment transport.The cross-section-averaged sediment transport capacity and recovery coefficient are addressed in the suspended load model.This one-dimensional model,therefore,can be applied to fine suspended loads and to hyperconcentrated flows in the Yellow River.Moreover,a new discretization scheme for the equation of unsteady non-uniform suspended sediment transport is proposed.The model is calibrated using data measured from the Yantan Reservoir on the Hongshui River and the Sanmenxia Reservoir on the Yellow River.A comparison of the calculated water level and river bed deformation with field measurements shows that the improved numerical model is capable of predicting flow,sediment transport,bed changes,and bed-material sorting in various situations,with reasonable accuracy and reliability. | Hongwei FANG Minghong CHEN Qianhai CHEN | 2008 | International Journal of Sediment Research2008，23，4： | 24 |
| 5 | Genetic analysis and gene fine mapping for a rice novel mutant(rl_(9(t)))with rolling leaf character显示文摘Leaf shape is an important parameter for ideotype breeding in rice, and the rolling of leaf is also beneficial to efficient ripening of grains. This encourages the explorations of new genes that regulate leaf shape. In this study, genetic analysis and gene mapping were carried out for a novel rolling leaf mutant identified from japonica variety Zhonghua 11. The SSR marker analysis showed that the mutant was controlled by a single recessive gene (rl9(t)) lo- cated on chromosome 9. Fine mapping of the Rl9(t) locus was conducted with 30 new STS markers de- veloped around Rl9(t) anchored region based on the sequence diversity between Nipponbare and 93-11. The fine mapping necessitated the contruction of a PAC contig encompassing the Rl9(t) locus, which was delimited to a 42 kb region. This could therefore en- hance the cloning of the target gene in further stud- ies. | YAN Changjie YAN Song ZHANG Zhengqiu LIANG Guohua LU Jufei GU Minghong | 2006 | Chinese Science Bulletin2006，51，1： | 22 |
| 6 | Size distribution of chemical elements and their source apportionment in ambient coarse, fine, and ultrafine particles in Shanghai urban summer atmosphere显示文摘Ambient coarse particles (diameter 1.8-10 μm), fine particles (diameter 0.1-1.8 μm), and ultrafine particles (diameter < 0.1 μm) in the atmosphere of the city of Shanghai were sampled during the summer of 2008 (from Aug 27 to Sep 08). Microscopic characterization of the particles was investigated by scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM/EDX). Mass concentrations of Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Br, Rb, Sr, and Pb in the size-resolved particles were quantified by using synchrotron radiation X-ray fluorescence (SRXRF). Source apportionment of the chemical elements was analyzed by means of an enrichment factor method. Our results showed that the average mass concentrations of coarse particles, fine particles and ultrafine particles in the summer air were 9.38 ± 2.18, 8.82 ± 3.52, and 2.02 ± 0.41 μg/m3, respectively. The mass percentage of the fine particles accounted for 51.47% in the total mass of PM10, indicating that fine particles are the major component in the Shanghai ambient particles. SEM/EDX results showed that the coarse particles were dominated by minerals, fine particles by soot aggregates and fly ashes, and ultrafine particles by soot particles and unidentified particles. SRXRF results demonstrated that crustal elements were mainly distributed in the coarse particles, while heavy metals were in higher proportions in the fine particles. Source apportionment revealed that Si, K, Ca, Fe, Mn, Rb, and Sr were from crustal sources, and S, Cl, Cu, Zn, As, Se, Br, and Pb from anthropogenic sources. Levels of P, V, Cr, and Ni in particles might be contributed from multi-sources, and need further investigation. | Senlin Lu Rui Zhang Zhenkun Yao Fei Yi Jingjing Ren Minghong Wu Man Feng Qingyue Wang | 2012 | Journal of Environmental Sciences2012，24，5： | 22 |
| 7 | Wx^lv、the Ancestral Allele of Rice Waxy Gene显示文摘In rice grains,the Waxy (Wx) gene is responsible for the synthesis of amylose,the most important determinant for eating and cooking quality.The effects of several Wx alleles on amylose content and the taste of cooked rice have been elucidated.However,the relationship between artificial selection and the evolution of various Wx alleles as well as their distribution remain unclear.Here we report the identification of an ancestral allele,Wx^lv,which dramatically affects the mouthfeel of rice grains by modulating the size of amylose molecules.We demonstrated that WF originated directly from wild rice,and the three major Wx alleles in cultivated rice (Wx^b,Wx^a,and Wx^in) differentiated after the substitution of one base pair at the functional sites.These data indicate that the Wx^lv allele played an important role in artificial selection and domestication.The findings also shed light on the evolution of various Wx alleles,which have greatly contributed to improving the eating and cooking quality of rice. | Changquan Zhang Jihui Zhu Shengjie Chen Xiaolei Fan Qianfeng Li Yan Lu Min Wang Hengxiu Yu Chuandeng Yi Shuzhu Tang Minghong Gu Qiaoquan Liu | 2019 | Molecular Plant2019，12，8： | 22 |
| 8 | Introgression of qPE9-1 allele,conferring the panicle erectness,leads to the decrease of grain yield per plant in japonica rice(Oryza sativa L.)显示文摘圆锥花序建筑学是仔细与产量有关形成。qPE9-1 基因被证明了广泛地在产量很高的米饭栽培变种开发被过去常,授与在装饰用的梨树米饭的直立的圆锥花序特性。最近, qPE9-1 成功地被克隆;然而,谷物产量上的基因效果还每直立的圆锥花序等位基因 qPE9-1 的植物是争论的。在现在的学习,低垂的圆锥花序父母 Nongken 57,带 qpe9-1 等位基因,被用作周期性父母到连续地回交到从双 haploid (DH ) 的一根典型直立的圆锥花序线人口(Wuyunjing 8/Nongken 57 ) ,它以前被显示带 qPE9-1 等位基因。因此,一双 near-isogenic 线(无) 被开发。在无之间的农学的特点的比较证明当 qpe9-1 被 qPE9-1 代替时,圆锥花序建筑学从低垂树立被改变;而且,圆锥花序长度,植物高度, 1000 谷物重量和 tillers 显著地被减少,因而在 30% 每植物导致谷物产量的戏剧的减少。因此,我们断定 qPE9-1 是控制圆锥花序建筑学的一个主要因素,并且 qPE9-1 有多种的自然,与每植物的谷物产量上的否定效果。这结果强烈建议直立的圆锥花序等位基因 qPE9-1 应该在产量很高的繁殖实践和另外的有利基因被使用。另外,吃并且煮质量上的 qPE9-1 的效果也在现在的学习被讨论。 | Xiuhua Yi Zujian Zhang Shengyuan Zeng Chunyan Tian Juncheng Peng Min Li Yue Lu Qingcai Meng Minghong Gu Changjie Yan | 2011 | Journal of Genetics and Genomics2011，38，5： | 20 |
| 9 | China’s Potential of Grain Production Due to Changes in Agricultural Land Utilization in Recent Years显示文摘The changes in utilization of agricultural land have gradually grown into one of the major factors impacting grain output in China. This study explores the various components of agricultural production in China from the land utilization perspective, involving changes in grain production per unit area, multi-cropping index, and adjustment of agricultural structure. Compared with the record values, different research methodologies are used to analyze the po- tential of above three components. The results indicate that grain production potential of 65.68×109kg was unexploited in 2006, in which 45.8×109kg came from the restructuring in agriculture. So we can infer that the reduction of grain production in China could be primarily attributed to agricultural restructuring in recent years. So the productive poten- tial can be fully restored by increasing agricultural investment, or recovering agricultural structure in favorable condi- tions. So we can say that China’s current condition of food security is good. | XIN Liangjie LI Xiubin ZHU Huiyi TAN Minghong | 2009 | Chinese Geographical Science2009，19，2： | 19 |
| 10 | Polychlorinated biphenyls in the atmosphere of Taizhou,a major e-waste dismantling area in China显示文摘PM2.5,total suspended particles(TSP) and gas phase samples were collected at two sites of Taizhou,a major e-waste dismantling area in China.Concentrations,seasonal variations,congener profiles,gas-particle partitioning and size distribution of the atmospheric polychlorinated biphenyls(PCBs) were studied to assess the current state of atmospheric PCBs after the phase out of massive historical dismantling of PCBs containing e-wastes.The average 38PCBs concentration in the ambient air(TSP plus gas phase) near the e-waste dismantling area was(12,407 ± 9592) pg/m3 in winter,which was substantially lower than that found one decade ago.However,the atmospheric PCBs level near the e-waste dismantling area was 54 times of the reference urban site,indicating that the impact of the historical dismantling of PCBs containing e-wastes was still significant.Tri-Penta-CBs were dominant homologues,consisting with their dominant global production.Size distribution of particle-bound PCBs showed that higher chlorinated CBs tended to partition more to the fine particles,facilitating its long range air transportation. | Wenliang Han Jialiang Feng Zeping Gu Minghong Wu Guoying Sheng Jiamo Fu | 2010 | Journal of Environmental Sciences2010，22，4： | 18 |
| 11 | A rare Waxy allele coordinately improves rice eating and cooking quality and grain transparency显示文摘In rice(Oryza sativa), amylose content(AC) is the major factor that determines eating and cooking quality(ECQ). The diversity in AC is largely attributed to natural allelic variation at the Waxy(Wx)locus. Here we identified a rare Wx allele, Wx^(mw) ,which combines a favorable AC, improved ECQ and grain transparency. Based on a phylogenetic analysis of Wx genomic sequences from 370 rice accessions, we speculated that Wx^(mw) may have derived from recombination between two important natural Wx alleles, Wx^(in) and Wx^(b). We validated the effects of Wx^(mw) on rice grain quality using both transgenic lines and near-isogenic lines(NILs). When introgressed into the japonica Nipponbare(NIP) background, Wx^(mw) resulted in a moderate AC that was intermediate between that of NILs carrying the Wx^(b)allele and NILs with the Wx^(mp) allele. Notably, mature grains of NILs fixed for Wx^(mw) had an improved transparent endosperm relative to soft rice. Further, we introduced Wx^(mw) into a high-yielding japonica cultivar via molecular marker-assisted selection: the introgressed lines exhibited clear improvements in ECQ and endosperm transparency. Our results suggest that Wx^(mw) is a promising allele to improve grain quality, especially ECQ and grain transparency of high-yielding japonica cultivars, in rice breeding programs. | Changquan Zhang Yong Yang Shengjie Chen Xueju Liu Jihui Zhu Lihui Zhou Yan Lu Qianfeng Li Xiaolei Fan Shuzhu Tang Minghong Gu Qiaoquan Liu | 2021 | Journal of Integrative Plant Biology2021，63，5： | 18 |
| 12 | Genetic analysis and molecular mapping of a presenescing leaf gene psll in rice (Oryza sativa L.)显示文摘A rice psl1 (presenescing leaf) mutant was obtained from a japonica variety Zhonghua 11 via radiation of 60Co-γ in M2 generation. Every leaf of the mutant began to wither after it reached the big-gest length,while the leaves of the wild variety could keep green for 25―35 d. In this study,genetic analysis and gene mapping were carried out for the mutant identified. The SSR marker analysis showed that the mutant was controlled by a single recessive gene (psl1) located on chromosome 2. Fine mapping of the psl1 locus was conducted with 34 new STS markers developed around psl1 anchored region based on the sequence diversity between Nippon-bare and 93-11. The psl1 was further mapped be-tween two STS markers,STS2-19 and STS2-26,with genetic distances of 0.43 and 0.11 cM,respectively,while cosegregated with STS2-25. A BAC contig was found to span the psl1 locus,the region being delim-ited to 48 kb. This result was very useful for cloning of the psl1 gene. | WANG dun WU Shujun ZHOU Yong ZHOU Lihui XU Jiefen HU Jing FANG Yunxia GU Minghong LIANG Guohua | 2006 | Chinese Science Bulletin2006，51，24： | 16 |
| 13 | Diurnal variations of polycyclic aromatic hydrocarbons associated with PM_(2.5) in Shanghai, China显示文摘Forty-eight daily time interval PM2.5 samples were collected from December 2006 to January 2008 in an urban site in Shanghai, China. Concentrations and compositions of polycyclic aromatic hydrocarbons (PAHs) were analyzed with GC-MS to study the diurnal and seasonal variations and to identify the main emitting sources. The diurnal variation of the PAHs concentrations was greater in the late autumn and winter sampling days, and was greatly influenced by meteorological conditions such as wind speed and ambient temperature. The concentration of PAHs in the mornings (6:30-10:00) increased distinctly, and was high in the late autumn and winter sampling days, indicating the contribution from vehicle emissions during rush hours. The diurnal variation of the high molecular weight PAHs did not seem to be controlled by the shift of gas-particle partitioning due to temperature variation, instead, it could be indicative of the variation in the source. Statistical analyses showed that the concentrations of PAHs were negatively correlated with temperature and wind speed, and positively correlated with relative humidity. Diagnostic ratios of PAHs suggested mixed emission sources of petroleum and coal/biomass combustion for PAHs in the PM2.5 in Shanghai. | Zeping Gu Jialiang Feng Wenliang Han Li Li Minghong Wu Jiamo Fu Guoying Sheng | 2010 | Journal of Environmental Sciences2010，22，3： | 13 |

| 15 | Urban spatial development and land use in Beijing: Implications from London's experiences显示文摘Beijing is facing a huge challenge to manage the growth of its built-up area whilst also retaining both productive arable land and land for conservation purposes in order to simultaneously realize the three aims of economic development,protecting arable land and generating environmental improvements. Meanwhile,London,as a world city with more than 200 years of industrialization and urbanization,has accumulated rich theoretical and practical experiences for land use planning in a major urban area,such as the creation of Garden Cities,a designated Green Belt and New Towns. This paper firstly analyzes the main characteristics of the spatial distribution of the built-up area,arable land and conservation land in Beijing. Then,some of the key aspects of urban fringe planning in the London region are examined. Lastly,several implications from the experience of London are provided with respect to land-use planning for Beijing,concentrating on a re-appraisal of land-use functions around Beijing,measures to improve the green belt,the development of small towns to house rural-urban migrants and urban overspill,and effective implementation of land-use planning. | TAN Minghong GUY M.

| 16 | Development of gene-tagged molecular markers for starch synthesis-related genes in rice显示文摘Improving grain quality is an important goal in breeding new elite rice varieties,requiring effective tools for the identification of target genotypes.Molecular marker-aided selection(MAS),combined with conventional breeding approaches,enables us to pre-cisely identify the individual genotypes that are associated with different grain quality features,which can dramatically improve the breeding efficiency.However,to date,the number of molecular markers used in MAS for grain quality improvement is still somewhat limited.In this study,based on our previous study that rice grain quality is strongly associated with starch synthesis in the endosperm,we developed 51 gene-tagged molecular markers according to sequence variations in 18 starch synthesis-related genes from 16 typical rice cultivars.These markers can discriminate the different alleles among rice germplasms.These novel markers will provide effective tools in improving grain quality via the breeding new elite rice varieties. | TIAN ZhiXi YAN ChangJie QIAN Qian YAN Song XIE HuiLan WANG Fang XU JieFen LIU GuiFu WANG YongHong LIU QiaoQuan TANG ShuZhu LI JiaYang GU MingHong | 2010 | Chinese Science Bulletin2010，55，33： | 12 |
| 17 | Experiment on surface charge distribution of fine sediment显示文摘Surface charge distribution of particles is the fundamental problem for adsorption and desorption between sediment and contaminant. In this paper, we take quartz sand for example to measure its micro-morphology and surface charge distribution using the phase mode of the electrical force microscope. Then the statistical relation of micro-morphology and surface charge distribution is obtained. Results show that quartz sand possesses complex surface morphology, which has great impact on the charge distribution. Positive and negative charges mostly concentrate on the saddle, convex and concave parts of the surface, while distribute less in the groove, ridge and flat parts. This experiment provides a new method for understanding the process of flocculation in coastal and estuarine zone. | HUANG Lei FANG HongWei CHEN MingHong | 2012 | Science China(Technological Sciences)2012，55，4： | 12 |
| 18 | Initial virtual flight test for a dynamically similar aircraft model with control augmentation system显示文摘To satisfy the validation requirements of flight control law for advanced aircraft,a wind tunnel based virtual flight testing has been implemented in a low speed wind tunnel.A 3-degree-offreedom gimbal,ventrally installed in the model,was used in conjunction with an actively controlled dynamically similar model of aircraft,which was equipped with the inertial measurement unit,attitude and heading reference system,embedded computer and servo-actuators.The model,which could be rotated around its center of gravity freely by the aerodynamic moments,together with the flow field,operator and real time control system made up the closed-loop testing circuit.The model is statically unstable in longitudinal direction,and it can fly stably in wind tunnel with the function of control augmentation of the flight control laws.The experimental results indicate that the model responds well to the operator's instructions.The response of the model in the tests shows reasonable agreement with the simulation results.The difference of response of angle of attack is less than 0.5°.The effect of stability augmentation and attitude control law was validated in the test,meanwhile the feasibility of virtual flight test technique treated as preliminary evaluation tool for advanced flight vehicle configuration research was also verified. | Guo Linliang Zhu Minghong Nie Bowen Kong Peng Zhong Chengwen | 2017 | Chinese Journal of Aeronautics2017，30，2： | 12 |
| 19 | ELE restrains empty glumes from developing into lemmas显示文摘Although there is evident homology among reproductive organs when comparing Poaceae (grass) and eudicots, the identity of grass specific organs, such as lodicules, palea, lemma, and glumes has been the subject of a vast and largely inconclusive discussion. Here we provide some direct evidence to support the idea that the empty glumes of rice (Oryza sativa) are counterparts of lemmas. We show that the development of empty glumes is regulated by ELE (elongated empty glume), which belongs to a plant specific novel gene family. Mutations at the ELE locus cause elongated empty glumes, which mimic the lemmas and have the epidermal morphology of lemmas with four or five vascular bundles. As a nuclear-localized gene, ELE is specifically expressed at the empty glumes of immature spikelets, and its ectopic expression causes many floral development defects, including lemma-like palea, extra palea-like structures, elongated lodicules, extra stamens and stigmas. Our result suggests that empty glumes are lemmas of the sterile florets located at the lateral side of the rice spikelet, and ELE acts as a regulator restraining its growth to maintain its small size in wild-type plants. | Lilan Hong Qian Qian Keming Zhu Ding Tang Zejun Huang Ling Gao Ming Li Minghong Gu Zhukuan Cheng | 2010 | Journal of Genetics and Genomics2010，37，2： | 11 |
