| 4 | GRAIN INCOMPLETE FILLING 2 regulates grain filling and starch synthesis during rice caryopsis development显示文摘Rice grain filling determines grain weight,final yield and grain quality.Here,a rice defective grain filling mutant,gif2,was identified.Grains of gif2 showed a slower filling rate and a significant lower final grain weight and yield compared to wild-type.The starch content in gif2 was noticeably decreased and its physicochemical properties were also altered.Moreover,gif2 endosperm cells showed obvious defects in compound granule formation.Positional cloning identified GIF2 to encode an ADP-glucose pyrophosphorylase(AGP) large subunit,AGPL2;consequently,AGP enzyme activity in gif2 endosperms was remarkably decreased.GIF2 is mainly expressed in developing grains and the coded protein localizes in the cytosol.Yeast two hybrid assay showed that GIF2 interacted with AGP small subunits Os AGPS1,Os AGPS2a and Os AGPS2 b.Transcript levels for granule-bound starch synthase,starch synthase,starch branching enzyme and starch debranching enzyme were distinctly elevated in gif2 grains.In addition,the level of nucleotide diversity of the GIF2 locus was extremely low in both cultivated and wild rice.All of these results suggest that GIF2 plays important roles in the regulation of grain filling and starch biosynthesis during caryopsis development,and that it has been preserved during selection throughout domestication of modern rice. | Xiangjin Wei Guiai Jiao Haiyan Lin Zhonghua Sheng Gaoneng Shao Lihong Xie Shaoqing Tang Qingguo Xu Peisong Hu | 2017 | Journal of Integrative Plant Biology2017，59，2： | 20 |
| 5 | Geographical characteristics of China’s wetlands derived from remotely sensed data显示文摘In this paper, we report the first wetland mapping of the entire China using Landsat enhanced thematic mapper plus (ETM+) data. These data were obtained from the Global Land Cover Facility at the University of Maryland spanning from 1999 to 2002. A total of 597 scenes of Landsat images were georeferenced and mosaiced. Manual image interpretation of satellite images was aided with elevation data, soil data, land cover/land use data and Google Earth. The minimum mapping unit is 10 pixel × 10 pixel, equivalent to 9 ha. The aim of our first round of mapping was only targeted at the boundary delineation of any type of wetland except those wetlands that are under agricultural use (i.e., paddy fields), which has already been well mapped by others. Our interpretation results indicate that a total of 359478 km2 of wetlands are of non-agricultural use. Among our preliminarily mapped wetland, 339353 km2 are inland wetland, 2786 km2 are non-agricultural artificial wetland, and 17609 km2 are coastal wetland. Because low-tide is rarely captured in satellite images, an under-estimation of coastal wetland is inevitable. We conducted some statistics based on our mapped wetlands and compared them with those previously obtained from a number of sources including a land cover/land use map made with satellite images during the late 1990s and early 2000s, a marshland map developed in approximately the same period, survey data of coastal wetland in early 1980s, and area data for approximately 400 larger patches of marshland in China compiled in 1996. Because some inconsistencies exist in the guidelines of those different wetland surveys, difference in area is expected. Some further comparison indicates that the wetland distributions derived from the preliminary wetland map are reasonable and more objective than other sources. The mapping process also indicated that the method adopted by us was efficient and cost-effective. We also found that in order to ensure comparability of the wetland maps developed at different times, a set of standard guidelines on the wetland categories to be mapped, and the mapping methods to be used must be well conceived, developed and effectively employed. We carried out some initial geographical analysis on the distribution of wetlands. | NIU ZhenGuo GONG Peng CHENG Xiao GUO JianHong WANG Lin HUANG HuaBing SHEN ShaoQing WU YunZhao WANG XiaoFeng WANG XianWei YING Qing LIANG Lu ZHANG LiNa WANG Lei YAO Qian YANG ZhenZhong GUO ZiQi DAI YongJiu | 2009 | Science China Earth Sciences2009，52，6： | 15 |
| 6 | Aerosol effects on ozone concentrations in Beijing:A model sensitivity study显示文摘Most previous O 3 simulations were based only on gaseous phase photochemistry.However,some aerosol-related processes,namely,heterogeneous reactions occurring on the aerosol surface and photolysis rate alternated by aerosol radiative influence,may affect O 3 photochemistry under high aerosol loads.A three-dimensional air quality model,Models-3/Community Multi-scale Air Quality-Model of Aerosol Dynamics,Reaction,Ionization,and Dissolution,was employed to simulate the effects of the above-mentioned processes on O 3 formation under typical high O 3 episodes in Beijing during summer.Five heterogeneous reactions,i.e.,NO 2,NO 3,N 2 O 5,HO 2,and O 3,were individually investigated to elucidate their effects on O 3 formation.The results showed that the heterogeneous reactions significantly affected O 3 formation in the urban plume.NO 2 heterogeneous reaction increased O 3 to 90 ppb,while HO 2 heterogeneous reaction decreased O 3 to 33 ppb.In addition,O 3 heterogeneous loss decreased O 3 to 31 ppb.The effects of NO 2,NO 3,and N 2 O 5 heterogeneous reactions showed opposite O 3 concentration changes between the urban and extra-urban areas because of the response of the reactions to the two types of O 3 formation regimes.When the aerosol radiative influence was included,the photolysis rate decreased and O 3 decreased significantly to 73 ppb O 3.The two aerosol-related processes should be considered in the study of O 3 formation because high aerosol concentration is a ubiquitous phenomenon that affects the urban-and regional air quality in China. | Jun Xu Yuanhang Zhang Shaoqing Zheng Youjiang He | 2012 | Journal of Environmental Sciences2012，24，4： | 15 |

| 9 | GBSS-BINDING PROTEIN,encoding a CBM48 domain-containing protein,affects rice quality and yield^∞显示文摘The percentage of amylose in the endosperm of rice(Oryza sativa)largely determines grain cooking and eating qualities.Granule-bound starch synthase I(GBSSI)and GBSSII are responsible for amylose biosynthesis in the endosperm and leaf,respectively.Here,we identified OsGBP,a rice GBSS-binding protein that interacted with GBSSI and GBSSII in vitro and in vivo.The total starch and amylose contents in osgbp mutants were significantly lower than those of wild type in leaves and grains,resulting in reduced grain weight and quality.The carbohydrate-binding module 48(CBM48)domain present in the C-terminus of OsGBP is crucial for OsGBP binding to starch.In the osgbp mutant,the extent of GBSSI and GBSSII binding to starch in the leaf and endospermwas significantly lower than wild type.Our data suggest that OsGBP plays an important role in leaf and endosperm starch biosynthesis by mediating the binding of GBSS proteins to developing starch granules.This elucidation of the function of OsGBP enhances our understanding of the molecular basis of starch biosyn-thesis in rice and contributes information that can be potentially used for the genetic improvement of yield and grain quality. | Wei Wang Xiangjin Wei Guiai Jiao Wenqiang Chen Yawen Wu Zhonghua Sheng Shikai Hu Lihong Xie Jiayu Wang Shaoqing Tang Peisong Hu | 2020 | Journal of Integrative Plant Biology2020，62，7： | 12 |
| 10 | Realizing over 10% efficiency in polymer solar cell by device optimization显示文摘The low band gap polymer based on benzodithiophene(BDT)-thieno[3,4-b]thiophene(TT)backbone,PBDT-TS1,was synthesized following our previous work and the bulk heterojunction(BHJ)material comprising PBDT-TS1/PC71BM was optimized and characterized.By processing the active layer with different additives i.e.1,8-diiodooctane(DIO),1-chloronaphthalene(CN)and 1,8-octanedithiol(ODT)and optimizing the ratio of each additive in the host solvent,a high PCE of 9.98%was obtained under the condition of utilizing 3%DIO as processing additive in CB.The effect of varied additives on photovoltaic performance was illustrated with atomic force microscopy(AFM)and transmission electron microscope(TEM)measurements that explained changes in photovoltaic parameters.These results provide valuable information of solvent additive choice in device optimization of PBDTTT polymers,and the systematic device optimization could be applied in other efficient photovoltaic polymers.Apparently,this work presents a great advance in single junction PSCs,especially in PSCs with conventional architecture. | Shaoqing Zhang Long Ye Wenchao Zhao Bei Yang Qi Wang Jianhui Hou | 2015 | Science China Chemistry2015，58，2： | 12 |
| 11 | Targeted mutagenesis of POLYAMINE OXIDASE 5 that negatively regulates mesocotyl elongation enables the generation of direct-seeding rice with improved grain yield显示文摘Under conditions of labor or resource scarcity,direct seeding,rather than transplantation,is the preferred mode of rice(Oryza sativa)cultivation.This approach requires varieties that exhibit uniform seedling emergence.Mesocotyl elongation(ME),the main driver of rapid emergence of rice seedlings from soil,is enhanced by darkness and inhibited by light.Plant polyamine oxidases(PAOs)oxidize polyamines(PAs)and release H2O2,Here,we established that OsPAO5 expression in rice seedlings is increased in the presence of light and inhibited by darkness.To determine its role in ME,we created OsPAO5 mutants using CRISPR/Cas9.Compared with the wild type,pao5 mutants had longer mesocotyls,released less H2O2,and synthesized more ethylene.The mutant seedlings emerged at a higher and more uniform rate,indicating their potential for use in direct seeding.Nucleotide polymorphism analysis revealed that an SNP(PAO5-578G/A)located 578 bp upstream of the OsPAO5 start codon alters its expression,and was selected during rice mesocotyl domestication.The PAO5-578G genotype conferring a long mesocotyl mainly exists in wild rice,most Aus accessions,and some Geng(Japonica)accessions.Intriguingly,knocking out OsPAO5 can remarkably increase the grain weight,grain number,and yield potential.In summary,we developed a novel strategy to obtain elite rice with higher emergence vigor and yield potential,which can be conveniently and widely used to breed varieties of direct-seeding rice. | Yusong Lv Gaoneng Shao Guiai Jiao Zhonghua Sheng Lihong Xie Shikai Hu Shaoqing Tang Xiangjin Wei Peisong Hu | 2021 | Molecular Plant2021，14，2： | 12 |
| 12 | 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 |
| 13 | Editing of Rice Isoamylase Gene ISA1 Provides Insights into Its Function in Starch Formation显示文摘Isoamylase 1(ISA1) is an isoamylase-type debranching enzyme which plays a predominant role in amylopectin synthesis. In this study, the clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated endonuclease 9(CRISPR/Cas9) system was used to edit ISA1 gene in rice via Agrobacterium-mediated transformation. We identified 36 genetic edited lines from 55 T_0 transgenic events, and classified the mutation forms into 7 types. Of those, two homozygous mutants, cr-isa1-1(type 1, with an adenine insertion) and cr-isa1-2(type 3, with a cytosine deletion) were selected for further analysis. Seed sizes of both cr-isa1-1 and cr-isa1-2 were affected, and the two mutants also displayed a shrunken endosperm with significantly lower grain weight. Electron microscopy analysis showed that abnormal starch granules and amyloplasts were found in cr-isa1-1 and cr-isa1-2 endosperm cells. The contents of total starch, amylose and amylopectin in the endosperm of the cr-isa1 mutants were significantly reduced, whereas sugar content and starch gel consistency were observably increased compared to the wild-type. The gelatinization temperature and starch chain length distributions of the cr-isa1 mutants were also altered. Moreover, transcript levels of most starch synthesis-related genes were significantly lower in cr-isa1 mutants. In conclusion, the results indicated that gene edition of ISA1 affected starch synthesis and endosperm development, and brought potential implications for rice quality breeding. | CHAO Shufen CAI Yicong FENG Baobing JIAO Guiai SHENG Zhonghua LUO Ju TANG Shaoqing WANG Jianlong HU Peisong WEI Xiangjin | 2019 | Rice science2019，26，2： | 10 |
| 14 | Tectonic Constraints on the Transformation of Paleozoic Framework of Uplift and Depression in the Ordos Area显示文摘During the Paleozoic, the Ordos area in the western North China Plate was located at the intersecting position of microplates and controlled by their interaction. The structural framework in the Ordos area, which underwent transformations in the Ordovician, the Carboniferous and the Permian respectively, was dominated by the alternation of uplift and depression. The transformations of structural framework are utilized as the clues to investigate the microplates’ interacting type and its response in the Ordos area. According to the regional structural evolution, the Ordos area is simplified into an isopachous, isotropic and elastic shell model, and under proposed various boundary conditions, three series of numerical simulations corresponding to the three structural transformations are carried out to determine the detailed tectonic constraints. Numerical simulations reveal that the structure of the uplift and depression, which is similar to the actual pattern, develops only under one special boundary condition in each of the three series, indicating that the structural framework responds to the unique tectonic background. The simulation results show that in the Early Paleozoic, the L-shaped paleouplift formed nearby the southwestern corner of the Ordos area because the intensity of the compressions in the southern and western boundaries resulting from the ocean-continent collisions was similar. In the Late Paleozoic, it evolved into continent-continent (or arc-continent) interaction in the southern and northern boundaries; in the preliminary stage of the interaction, since the interface between the North China Plate and the plates on the south and north was narrow, the relative acting force was little and the regional western boundary immobile, and the structural framework in the basin was characterized by the N-S trending slender-waist-shaped uplift; as the interface between the plates expanded gradually, the extrusive force in the southern and northern boundaries of the North China Plate increased, resulting in the paleogeographic divisions showing E-W trending, and, the western boundary of the basin was extruded westward due to the intense compression inducing the local NE trending of paleogeographic division in the central area. The simulation results further reflect that the symmetry of the uplift-depression pattern is restricted by that of the boundary conditions, suggesting that the Paleozoic structural transformations of the Ordos area under boundary constraints accord with the universal physical symmetrical principle. | WANG Qingfei DENG Jun HUANG Dinghua YANG Liqiang GAO Bangfei XU Hao JIANG Shaoqing | 2006 | Acta Geologica Sinica(English Edition)2006，80，6： | 10 |

| 17 | Microstructure Evolution and Tensile Properties of Ti_3Al/Ni-based Superalloy Welded Joint显示文摘In the present work,the dissimilar joining of a Ti_3AI-based alloy to a Ni-based superalloy was attempted by gas tungsten arc(GTA) welding technology.Sound joints were successfully achieved by using a Cu—Ni alloy as filler material.According to X-ray energy dispersive spectroscopy and X-ray diffraction analysis results three transitional layers at the weld/Ti_3AI interface were verified as follows:Ti_2AINb phase dissolved with Cu and Ni;AI(Cu,Ni)_2Ti,(Cu,Ni)_2Ti and(Nb,Ti) solid solution;Cu-rich phase and a complex multi-element phase.The In718/weld interface is characterized by solid solutions of Ni,Cu,Cr,Fe and Nb.The average tensile strength of the as-welded joints at room temperature is 1 63 MPa,and after a post—weld heat treatment it is increased slightly to 177 MPa.The fracture occurred at the surfacial layer of the joined Ti_3AI base alloy,indicating that the Ti_2AINb layer dissolved with Cu and Ni is the weak link of the Ti_3AI/ln71 8 joint. | Bingqing Chen Huaping Xiong Bingbing Sun Siyi Tang Shaoqing Guo Xuejun Zhang | 2014 | Journal of Materials Science & Technology2014，30，7： | 7 |
| 18 | Geochemistry and genesis of authigenic pyrite from gas hydrate accumulation system in the Qilian Mountain permafrost, Qinghai, northwest China显示文摘A type of authigenic pyrites that fully fill or semi-fill the rock fractures of drillholes with gas hydrate anomalies are found in the Qilian Mountain permafrost; this type of pyrite is known as 'fracture-filling' pyrite. The occurrence of 'fracture-filling' pyrite has a certain similarity with that of the hydrate found in this region, and the pyrite is generally concentrated in the lower part of the hydrate layer or the hydrate anomaly layer. The morphology, trace elements, rare earth elements, and sulfur isotope analyses of samples from drillhole DK-6 indicate that the 'fracture-filling' pyrites are dominated by cubic ones mainly aligned in a step-like fashion along the surfaces of rock fractures and are associated with a circular structure, lower Co/Ni and Sr/Ba, lower ?REE, higher LREE, significant Eu negative anomalies, and ? 34 SCDT positive bias. In terms of the pyrites' unique crystal morphology and geochemical characteristics and their relationship with the hydrate layers or abnormal layers, they are closely related with the accumulation system of the gas hydrate in the Qilian Mountain permafrost. As climate change is an important factor in affecting the stability of the gas hydrate, formation of fracture-filling pyrites is most likely closely related to the secondary change of the metastable gas hydrate under the regional climate warming. The distribution intensity of these pyrites indicates that when the gas hydrate stability zone(GHSZ) is narrowing, the hydrate decomposition at the bottom of the GHSZ is stronger than that at the top of the GHSZ, whereas the hydrate decomposition within the GHSZ is relatively weak. Thus, the zone between the shallowest and the deepest distribution of the fracture-filling pyrite recorded the largest possible original GHSZ. | WANG PingKang ZHU YouHai LU ZhenQuan HUANG Xia PANG ShouJi ZHANG Shuai JIANG ShaoQing LI QingHai YANG KaiLi LI Bing | 2014 | Science China Earth Sciences2014，57，9： | 6 |
