| 1 | The HuangZaoSi Maize Genome Provides Insights into Genomic Variation and Improvement History of Maize显示文摘Maize is a globally important crop that was a classic model plant for genetic studies. Here, we report a 2.2 Gb draft genome sequence of an elite maize line, HuangZaoSi (HZS). Hybrids bred from HZS-improved lines (HILs) are planted in more than 60% of maize fields in China. Proteome clustering of six completed sequeneed maize genomes show that 638 proteins fall into 264 HZS-specific gene families with the majority of contributions from tandem duplication events. Resequencing and comparative analysis of 40 HZSrelated lines reveals the breeding history of HILs. More than 60% of identified selective sweeps were clustered in identity.by.descent conserved regions, and yield-related genes/QTLs were enriched in HZS characteristic selected regions. Furthermore, we dem on strated that HZS-specific family genes were not uniformly distributed in the genome but enriched in improvement/function.related genomic regions. This study provides an important and novel resource for maize genome research and expands our knowledge on the breadth of genomic variation and improvement history of maize. | Chunhui Li Wei Song Yingfeng Luo Shenghan Gao Ruyang Zhang Zi Shi Xiaqing Wang Ronghuan Wang Fengge Wang Jidong Wang Yanxin Zhao Aiguo Su Shuai Wang Xin Li Meijie Luo Shuaishuai Wang Yunxia Zhang Jianrong Ge Xinyu Tan Ye Yuan Xiaochun Bi Hang He Jianbing Yan Yuandong Wang Songnian Hu Jiuran Zhao | 2019 | Molecular Plant2019，12，3： | 15 |
| 2 | Detrital K-feldspar^(40)Ar/^(39)Ar Ages:Source Constraints of the Lower Miocene Sandstones in the Pearl River Mouth Basin,South China Sea显示文摘The South China Sea began to outspread in the Oligocene.A great quantity of terraneous detritus was deposited in the northern continental shelf of the sea,mostly in Pearl River Mouth Basin,which constituted the main paleo-Pearl River Delta.The delta developed for a long geological time and formed a superimposed area.Almost all the oil and gas fields of detrital rock reservoir distribute in this delta.Thirty-three oil sandstone core samples in the Zhujiang Formation,lower Miocene(23-16 Ma),were collected from nine wells.The illite samples with detrital K feldspar(Kfs) separated from these sandstone cores in four sub-structural belts were analysed by the high-precision 40Ar/39Ar laser stepwise heating technique.All 33 illite 40Ar/39Ar data consistently yielded gradually rising age spectra at the low-temperature steps until reaching age plateaus at mid-high temperature steps.The youngest ages corresponding to the beginning steps were interpreted as the hydrocarbon accumulation ages and the plateau ages in mid-high temperature steps as the contributions of the detrital feldspar representing the ages of the granitic parent rocks in the provenances.The ages of the detrital feldspar from the Zhujiang Formation in the four sub-structural belts were different:(1) the late Cretaceous ages in the Lufeng 13 fault structural belt;(2) the late Cretaceous and early Cretaceous-Jurassic ages in the Huizhou 21 buried hill-fault belt;(3) the Jurassic and Triassic ages in the Xijiang 24 buried hill-fault belt;and(4) the early Cretaceous-late Jurassic ages in the Panyu 4 oil area.These detrital feldspar 40Ar/39Ar ages become younger and younger from west to east,corresponding to the age distribution of the granites in the adjacent Guangdong Province,Southern China. | LIU Zaisheng SHI Hesheng ZHU Junzhang QIU Huaning ZHANG Zhilin YUN Jianbing | 2012 | Acta Geologica Sinica(English Edition)2012，86，2： | 9 |
| 3 | Planting density affected biomass and grain yield of maize for seed production in an arid region of Northwest China显示文摘Field experiments were conducted from 2012 to 2015 in an arid region of Northwest China to investigate the effects of planting density on plant growth, yield, and water use efficiency(WUE) of maize for seed production. Five planting densities of 6.75, 8.25, 9.75, 11.25 and 12.75 plants/m^2 were conducted in 2012, and a planting density of 14.25 plants/m^2 was added from 2013 to 2015. Through comparison with the Aqua Crop yield model, a modified model was developed to estimate the biomass accumulation and yield under different planting densities using adjustment coefficient for normalized biomass water productivity and harvest index. It was found that the modified yield model had a better performance and could generate results with higher determination coefficient and lower error. The results indicated that higher planting density increased the leaf area index and biomass accumulation, but decreased the biomass accumulation per plant. The total yield increased rapidly as planting density increased to 11.25 plants/m^2, but only a slight increase was observed when the density was greater than 11.25 plants/m^2. The WUE also reached the maximum when planting density was 11.25 plants/m^2, which was the recommended planting density of maize for seed production in Northwest China. | JIANG Xuelian TONG Ling KANG Shaozhong LI Fusheng LI Donghao QIN Yonghui SHI Rongchao LI Jianbing | 2018 | Journal of Arid Land2018，10，2： | 9 |
| 4 | Scientific challenges of research on natural hazards and disaster risk显示文摘As a discipline,the science of natural hazards and disaster risk aims to explain the spatial-temporal pattern,process and mechanism,emergency response and risk mitigation of natural hazards,which requires a multidisci-plinary and interdisciplinary approach.With the support of Natural Science Finance of China(NSFC)and Chinese Academy of Sciences(CAS),in-depth research and systematic analysis on natural hazards and disaster risk were conducted.In this paper,the state of the art in research on natural hazards is summarized from seven aspects:formation process,mechanism and dynamic of natural hazards,disaster risk assessment,forecast,monitoring and early warning,disaster mitigation,emergency treatment and rescue,risk management and post-disaster re-construction.The trends within the natural hazards and disaster risk as a discipline were identified,along with existing shortcomings and significant gaps that need to be addressed.This paper highlighted:1)the scientific challenges including the frontier scientific issues and technological gaps on natural hazards and disaster risk dis-cipline from 2025 to 2035 in China,and 2)the proposal to develop a systemic and holistic natural hazards and disaster risk discipline. | Peng Cui Jianbing Peng Peijun Shi Huiming Tang Chaojun Ouyang Qiang Zou Lianyou Liu Changdong Li Yu Lei | 2021 | Geography and Sustainability2021，2，3： | 3 |

| 6 | An AIEE polyelectrolyte as a light-up fluorescent probe for heparin sensing in full detection range显示文摘Polyelectrolyte PTPEPyH, containing tetraphenylethene (TPE) and pyridinium, was synthesized. Its optical properties were investigated with spectroscopies and the results showed that there were two emission-enhanced stages in the interaction between positive-charged PTPEPyH and negative-charged biomacromolecule heparin. The mechanism was very different due to the reduced non-radiative energy loss and the change of surroundings. The polyelectrolyte PTPEPyH, compared with ChS and HA, also showed high selectivity for heparin in the buffer solution and could be used as a potential bio-probe for heparin quantification in the clinical full range. | CHEN DongYang SHI JianBing WU YanMei TONG Bin ZHI JunGe DONG YuPing | 2013 | Science China Chemistry2013，56，9： | 2 |

| 8 | Organic Host-Guest Materials with Bright Red Room-Temperature Phosphorescence for Persistent Bioimaging显示文摘Organic room-temperature phosphorescence(RTP)materials have attracted immense attention in bioimaging due to their long emission lifetime and large Stokes shift.RTP materials with long emission wavelength can improve the penetration depth for bioimaging.However,the design of red persistent RTP materials is still challenging.In this study,a fused-ring structure has been proposed to effectively decrease the triplet energy level,thus extending the emission wavelength of phosphorescence.In addition,the fused-ring structure exhibits a high molar extinction coefficient(ɛ)and high luminescence efficiency due to the rigid structure.A new class of crystalline hosts(iminodibenzyl,IDB)are developed to stabilize the triplet excitons that are generated from the fused-ring molecules.The maximum RTP wavelength of doping materials can reach 635 nm with a lifetime of 9.35 ms.Water-disperse nanoparticles are successfully prepared for in vivo time-resolved bioimaging,which eliminates the background fluorescence interference from biological tissues.These reveal a delicate design strategy for the construction of long-wavelength emissive RTP materials for high-resolution bioimaging. | Yueyue Si Yeyun Zhao Wenbo Dai Shisheng Cui Peng Sun Jianbing Shi Bin Tong Zhengxu Cai Yuping Dong | 2023 | Chinese Journal of Chemistry2023，41，13： | 1 |

| 12 | Conformational sensitivity of tetraphenyl-1,3-butadiene derivatives with aggregation-induced emission characteristics显示文摘Organic dyes with conformational sensitivity can be used to probe weak interactions at the molecular level.Here,three molecules based on tetraphenyl-1,3-butadienes(TPBs)were synthesized and studied with respect to their synthesis,structural characterization and potential application.All TPBs showed aggregation-induced emission(AIE)characteristics and sensitive conformational properties,in which the emission wavelengths could be changed in different states.The TPBs single crystals revealed that the phenyl groups at the 4-position of the 1,3-butadienes contributed to their conformational sensitivity.Furthermore,the potential application for monitoring the interactions among polyelectrolyte complexes and metal ions was explored,and the results showed that TPBs could be used for sensitively probing some weak interactions by changing the emission wavelengths due to their conformation-sensitive properties.TPBs may become a new star in AIE research fields. | Yahui Zhang Huanyu Xu Weiquan Xu Chen Zhang Jianbing Shi Bin Tong Zhengxu Cai Yuping Dong | 2019 | Science China Chemistry2019，62，10： | 0 |
| 13 | Seismic description and fluid identification of thin reservoirs in Shengli Chengdao extra-shallow sea oilfield显示文摘The meandering channel deposit of the upper member of Neogene Guantao Formation in Shengli Chengdao extra-shallow sea oilfield is characterized by rapid change in sedimentary facies.In addition,affected by surface tides and sea water reverberation,the double sensor seismic data processed by conventional methods has low signal-to-noise ratio and low resolution,and thus cannot meet the needs of seismic description and oil-bearing fluid identification of thin reservoirs less than 10 meters thick in this area.The two-step high resolution frequency bandwidth expanding processing technology was used to improve the signal-to-noise ratio and resolution of the seismic data,as a result,the dominant frequency of the seismic data was enhanced from 30 Hz to 50 Hz,and the sand body thickness resolution was enhanced from 10 m to 6 m.On the basis of fine layer control by seismic data,three types of seismic facies models,floodplain,natural levee and point bar,were defined,and the intelligent horizon-facies controlled recognition technology was worked out,which had a prediction error of reservoir thickness of less than 1.5 m.Clearly,the description accuracy of meandering channel sand bodies has been improved.The probability semi-quantitative oiliness identification method of fluid by prestack multi-parameters has been worked out by integrating Poisson’s ratio,fluid factor,product of Lame parameter and density,and other prestack elastic parameters,and the method has a coincidence rate of fluid identification of more than 90%,providing solid technical support for the exploration and development of thin reservoirs in Shengli Chengdao extra-shallow sea oilfield,which is expected to provide reference for the exploration and development of similar oilfields in China. | SHU Ningkai SU Chaoguang SHI Xiaoguang LI Zhiping ZHANG Xuefang CHEN Xianhong ZHU Jianbing SONG Liang | 2021 | Petroleum Exploration and Development2021，48，4： | 0 |
| 14 | Donor strategy for promoting nonradiative decay to achieve an efficient photothermal therapy for treating cancer显示文摘Photothermal therapy(PTT)is emerging as an effective treatment for superficial carcinoma.A key challenge to the effectiveness of PTT is to develop photosensitizers with high photothermal conversion efficiency.Aiming to address this challenge,we develop a series of multi-arylpyrrole derivatives with different donors that contain different multi-rotor structures to explore highly efficient PTT photosensitizers.Among these multi-arylpyrrole derivatives,MAP4-FE nanoparticles with a small size of their donor groups and better-donating ability exhibit a high photothermal conversion efficiency(up to 72%)when they are encapsulated by an amphiphilic polymer.As a result,the MAP4-FE nanoparticles have shown satisfactory PTTeffects on in vivo tumor eradication under the guidance of photoacoustic signals.The findings of this study provide significant insights for the development of high-efficiency PTT photosensitizers for cancer treatment by making full use of the nonradiative decay of small size donors as rotors. | Fei Ren Zeshun Li Kai Li Xiaoyan Zheng Jianbing Shi Chen Zhang Heng Guo Bin Tong Lei Xi Zhengxu Cai Yuping Dong | 2021 | Science China Chemistry2021，64，9： | 0 |
| 15 | Effect of bilayer number on the photoluminescent property of TPE-based self-assembled film显示文摘Tetraphenylethylene (TPE) derivatives have been proved to be typical aggregation-induced emission (AIE) luminogens when they were aggregated in the free three-dimensional space. In order to reveal the effect of the dimensional degree on AIE property of TPEs, we utilized tetra(4-hydroxyphenyl)ethylene (TPE-4OH) and 1,4-benzenediamine diazonium salt (BD) to fabricate the ultrathin films (TPE-4OH/BD LBL SA film) through layer-by-layer self-assembled technique. The interaction between TPE-4OH and BD in the films was converted from electrostatic force and hydrogen-bond to covalent bonds through photodecomposition of diazonium groups under UV irradiation. Fluorescence emission spectroscopy, UV-Vis absorption spectroscopy and atomic force microscope were carried out to evaluate the relationship between bilayer number and photoluminescence of the TPE-based self-assembled films. The experimental results showed that the TPE-based film with three bilayers only displayed AIE character, whereas the fluorescence of the film became randomly changed if the bilayer number was above three. It is supposed that the fluorescence property of the TPE-4OH/BD LBL SA film with limited molecular length in z-axis and infinite aggregation space in x-and y-axis is dominated by two competitive effects, one is the partial restriction of intramolecular rotation through short inter-molecular interactions in cross-linked structure of TPE-4OH/BD, and the other is deactivation of its excited state through unrestricted intramolecular rotations or π-π interactions. | CHEN DiDi FENG Xiao GU ShangZhi TONG Bin SHI JianBing ZHI JunGe DONG YuPing | 2013 | Chinese Science Bulletin2013，58，22： | 0 |
| 16 | Selective detection of phosphaphenanthrene-containing luminophors with aggregation-induced emission enhancement to transition metal ions显示文摘Transition metal ions(Pb^(2+),Zn^(2+),Cd^(2+),Co^(2+),Mn^(2+),Cu^(2+),Ni^(2+),Hg^(2+),Ag^(+),Fe^(3+))in water are used to quench emission of 2-(6-oxido-6H-dibenz<1,2>oxaphosphorin-6-yl)-1,4-phenylene-bis(p-pentyloxylbenzoate)s(MD5)with aggregation-induced emission enhancement(AIEE)in water-acetonitrile(AN)mixture(80:20 by volume).Among all metal ions,Fe^(3+)exhibits the highest quenching efficiency on AIEE of MD5 even when the concentration of Fe^(3+)is lower than 1×10^(-6) mol/L.The quenching efficiency of Hg^(2+)is lower than that of Fe^(3+)at the same concentration,though MD5 is used to detect Hg^(2+)efficiently,too.To other metal ions,low quenching efficiency has few relations with a wider concentration range.The UV absorbance spectra show only red shift of absorbance wavelength in the presence of Hg^(2+)and Fe^(3+),which indicates a salt-induced Jaggregation.SEM photos reveal larger aggregation and morphological change of nanoparticles of MD5 in water containing Hg^(2+)and Fe^(3+),which reduce the surface area of MD5 emission for further aggregation.The selective quenching effect of transition metal ions to emission of MD5 has a potential application in chemical sensors of some metal ions. | Lijun QIAN Bin TONG Shu SUN Jianbing SHI Junge ZHI Yuping DONG | 2011 | Frontiers of Chemistry in China2011，6，1： | 0 |

| 18 | Wide-range color-tunable afterglow emission by the modulation of triplet exciton transition processes based on buckybowl structure显示文摘Buckybowl structures as non-uniform electrostatic potential distributions of poly-cyclic aromatic materials show a unique photoelectric performance.In this work,OTC was utilized for dynamic modulation of triplet exciton transition processes.Five host molecules with different functional units were selected,thus providing dif-ferent intermolecular interactions in the host/guest systems.Therefore,the delayed emissions were regulated from 536 to 624 nm via the tuning of the triplet exciton transition processes of OTC in different hosts.Experimental data and theoretical calculations revealed that the varied triplet transition behaviors resulted from the competition between the intersystem crossing(ISC)process of OTC-monomer and the reverse intersystem crossing(RISC)process of OTC-aggregates.This work proves the superior structure of buckybowl-based luminophore for controlling triplet exciton transition processes and supplies a new perspective for persistent afterglow luminophore design. | Yongfeng Zhang Chenchen Xiong Wenbo Wang Wenbo Dai Yue Ren Junming Xia Gengchen Li Jianbing Shi Bin Tong Xiaoyan Zheng Xiangfeng Shao Zhengxu Cai Yuping Dong | 2023 | Aggregate2023，4，4： | 0 |
