| 1 | RLINl,encoding a putative coproporphyrinogen Ⅲ oxidase,is involved in lesion initiation in rice显示文摘Lesion mimic is necrotic lesions on plant leaf or stem in the absence of pathogenic infection,and its exact biological mechanism is varied.By a large-scale screening of our T-DNA mutant population,we identified a mutant rice lesion initiation 1(rlin1),which was controlled by a single nuclear recessive gene.Map-based cloning revealed that RLIN1 encoded a putative coproporphyrinogen Ⅲ oxidase in tetrapyrrole biosynthesis pathway.Sequencing results showed that a G to T substitution occurred in the second exon of RLIN1 and led to a missense mutation from Asp to Tyr.Ectopic expression of RLIN1 could rescue rlin1 lesion mimic phenotype.Histochemical analysis demonstrated that lesion formation in rlin1 was light-dependent accompanied by reactive oxygen species accumulated.These results suggest that tetrapyrrole participates in lesion formation in rice. | Changhui Sun Linchuan Liu Jiuyou Tang Aihong Lin Fantao Zhang Jun Fang Genfa Zhang Chengcai Chu | 2011 | Journal of Genetics and Genomics2011，38，1： | 31 |

| 4 | Investigation of heavy metal partitioning influenced by flue gas moisture and chlorine content during waste incineration显示文摘The impact of moisture on the partitioning of the heavy metals including Pb,Zn,Cu and Cd in municipal solid waste (MSW) was studied in a laboratory tubular furnace.A thermodynamic investigation using CHEMKIN software was performed to compare the experimental results.Simulated waste,representative of typical MSW with and without chlorine compounds,was burned at the background temperature of 700 and 950°C,respectively.In the absence of chlorine,the moisture content has no evident effect on the volatility of Pb,Zn and Cu at either 700 or 950°C,however,as flue gas moisture increasing the Cd distribution in the bottom ash increased at 700°C and reduced at 950°C,respectively.In the presence of chlorine,the flue gas moisture reduced the volatility of Pb,Zn and Cu due to the transformation of the more volatile metal chlorides into less volatile metal oxides,and the reduction became significant as chlorine content increase.For Cd,the chlorine promotes its volatility through the formation of more volatile CdCl 2.As a result,the increased moisture content increases the Pb,Zn,Cu and Cd concentrations in the bottom ash,which limits the utilization of the bottom ash as a construction material.Therefore,in order to accumulate heavy metals into the fly ash,MSW should be dried before incineration. | Qinghai Li,Aihong Meng,Jinyan Jia,Yanguo Zhang Department of Thermal Engineering,Key Laboratory for Thermal Science and Power Engineering of the Ministry of Education of China,Tsinghua University,Beijing 100084,China. | 2010 | Journal of Environmental Sciences2010，22，5： | 24 |
| 5 | Effect of specimen size on energy dissipation characteristics of red sandstone under high strain rate显示文摘In this experiment, red sandstone specimens, having slenderness ratios of 0.5, 0.7, 0.9 and 1.1 respectively, were subjected to blow tests using a Split Hopkinson Pressure Bar(SHPB) system at a pressure of 0.4 atmospheres. In this paper, we have analyzed the effect of slenderness ratio on the mechanical properties and energy dissipation characteristics of red sandstone under high strain rates. The processes of compaction, elastic deformation and stress softening deformation of specimens contract with an increase in slenderness ratio, whilst the nonlinear deformation process extends correspondingly. In addition, degrees of damage of specimens reduced gradually and the type of destruction showed a transformation trend from stretching failure towards shear failure when the slenderness ratio increased. A model of dynamic damage evolution in red sandstone was established and the parameters of the constitutive model at different ratios of length to diameter were determined. By comparison with the experimental curve, the accuracy of the model, which could reflect the stress–strain dynamic characteristics of red sandstone, was verified. From the view of energy dissipation, an increase in slenderness ratio of a specimen decreased the proportion of energy dissipation and caused a gradual fall in the capability of energy dissipation during the specimen failure process. To some extent, the study indicated the effects of slenderness ratios on the mechanical properties and energy dissipation characteristics of red sandstone under the high strain rate, which provides valuable references to related engineering designs and academic researches. | Li Ming Mao Xianbiao Lu Aihong Tao Jing Zhang Guanghui Zhang Lianying Li Chong | 2014 | International Journal of Mining Science and Technology2014，24，2： | 24 |
| 6 | Analysis on water potential of Populus euphratica oliv and its meaning in the lower reaches of Tarim River,Xinjiang显示文摘Combined with materials measured on leaves water potential of Populus euphratica oliv in the process of ecological water delivery in the lower reaches of Tarim River, the influence of ground-water depths and soil salinity on leaves water potential of P. euphratica was analyzed. We found that there was evident negative correlation between the leaves water potential of P. euphratica and ground-water depths. The deeper the ground-water depths were, the lower the leaves water potential of P. euphratica was, the more serious drought stress P. euphratica suffered from. Besides, there was evident negative correlation between the soil salinity and the leaves water potential of P. euphratica. The bigger the soil salinity was, the lower the leaves water potential of P euphratica was, the more serious drought stress was indicated from which P. euphratica suffered. For sections rather distant for Daxihaizi Reservoir as well as for those places of wells rather distant from the river course, ground-water depths and the soil salinity were high; the leaves water potential of P. euphratica was low. The leaves water potential of P. euphratica can reflect the degree at which P. euphratica suffers from drought and salt stress, and has an important reference meaning in analyzing proper ground-water depths for the survival and growth of P. euphratic in the lower reaches of Tarim River. | FU Aihong CHEN Yaning LI Weihong | 2006 | Chinese Science Bulletin2006，51，A01： | 17 |

| 9 | Behavior and dynamics of gecko’s locomotion:The effects of moving directions on a vertical surface显示文摘The study of the movement behavior of geckos on a vertical surface, including the measurement and recording of the reaction forces as they move in different directions, plays an important role in understanding the mechanics of the animals' locomotion. This study provides inspiration for the design of a control system for a bionics robot. The three-dimensional reaction forces of vertical surface-climbing geckos (Gekko gecko) were measured using a three-dimensional force-sensors-array. The behavior of gecko as it moved on a vertical surface was recorded with a high speed camera at 215 fps and the function of each foot of a gecko are discussed in this paper. The results showed that the gecko increased its velocity of movement mainly by increasing the stride frequency in the upward, downward and leftward direction and that the speed had no significant relationship to the attachment and detachment times. The feet above the center-of-mass play a key role in supporting the body, driving locomotion and balancing overturning etc. The movement behavior and foot function of geckos change correspondingly for different conditions, which results in safe and effective free vertical locomotion. This research will be helpful in designing gecko-like robots including the selection of gait planning and its control. | WANG ZhouYi WANG JinTong JI AiHong ZHANG YueYun DAI ZhenDong | 2011 | Chinese Science Bulletin2011，56，6： | 12 |

| 11 | Water use strategies of the desert riparian forest plant community in the lower reaches of Heihe River Basin, China显示文摘The object of this paper is the different plant communities in the Ejina desert riparian forest.Groundwater depth,soil moisture,plant water potential,relative leaf moisture content and water use efficiency was monitored,and the response of soil moisture and plant ecology to the groundwater depth and the water use efficiency of the different plant communities was analyzed.The results showed that:(1)Along with the groundwater depth increasing,predawn and midday water potential of the plants,with the exception of Reaumuria soongorica,did not decrease significantly,indicating that when the groundwater depth is less than3 m,the plant communities in the range of 4 km from the river way did not suffer or slightly suffer from water stress;(2)The distribution of higher soil moisture content within 0–3 m soil layer is suitable with the plants’root system,as indicated in the communities of coexisting overripe Populus euphratica or Taramrix chinensis,both of which can release excessive water into soil for shallow rooted shrubs or herbaceous plants when there is water shortage;(3)R.soongorica can absorb deep soil moisture through deep roots for their own survival;(4)The community consisting of Sophora alopecuroides,Karelinia caspica,T.chinensis,and overripe P.euphratica has the best species combination for restoring the damaged eco-environment in the lower reaches of Heihe River;(5)The order of plants’relative leaf water contents is K.caspica>S.alopecuroides>young P.euphratica>overripe P.euphratica>mature P.euphratica=T.chinensis coexisting with other species>single R.soongorica>single T.chinensis and the order of WUE is single T.chinensis>single R.soongorica>T.chinensis living in symbiosis with other species>S.alopecuroides=young P.euphratica>mature P.euphratica>overripe P.euphratica>K.caspica.Therefore,with ample soil moisture,the plant community helps rapid growth of T.chinensis,young P.euphratica and R.soongorica plants of less moisture content.Despite this they do not have much water storage capability,but have strong drought resistance,and higher moisture contents of S.alopecuroides and K.caspica,thus leaving them with poor drought resistance.Overall,the desert riparian forest plant community in the lower reaches of Heihe River helps the species of higher WUE live on it. | FU AiHong CHEN YaNing LI WeiHong | 2014 | Science China Earth Sciences2014，57，6： | 10 |
| 12 | Characterization and evaluation of rice blast resistance of Chinese indica hybrid rice parental lines显示文摘The development of resistant varieties and hybrid combinations has been the most effective and economical strategy to control blast disease caused by Magnaporthe oryzae.However, the distribution of major R genes and blast resistance characterization in hybrid rice parents has not been well investigated, resulting in their limited use in hybrid rice blast-resistance breeding. In the present study, 88 elite indica hybrid rice parental lines were evaluated with 30 isolates of M. oryzae collected from the main planting area of indica hybrid rice in China and were characterized for the presence of 11 major resistance genes using molecular markers. The pathogenicity assays showed that four types of hybrid rice parent line showed some resistance to M. oryzae. However, the proportions of highly resistant lines and the mean resistance frequency(RF) varied among the four types, with resistance in decreasing order shown by three-line restorer lines, three-line maintainer lines, two-line sterile lines, and two-line restorer lines. All 88 hybrid rice parental lines carried more than one R gene, but none carried the R genes Pi1 and Pi2. Although Pid3 and Pi9 were present only in three-line restorer lines and Pigm only in three-line maintainer lines, the remaining six R genes(Pib, Pid2, Pi5, Pia, Pi54, and Pita) were present in the four types of hybrid rice parent with significantly different distribution frequencies. The correlation between R genes and resistance reactions was investigated. The results are expected to provide useful information for rational utilization of major R genes in hybrid rice breeding programs. | Yunyu Wu Ling Yu Ning Xiao Zhengyuan Dai Yuhong Li Cunhong Pan Xiaoxiang Zhang Guangqing Liu Aihong Li | 2017 | The Crop Journal2017，5，6： | 10 |
| 13 | Molecular Cloning and Expression Analysis of the ζ-Carotene Desaturase Gene in Chinese kale(Brassica oleracea var.alboglabra Bailey)显示文摘ζ-Carotene desaturase(ZDS)is an important enzyme in carotenoid biosynthesis.Here,the Brassica oleracea var.alboglabra ZDS(Boa ZDS)gene was cloned from Chinese kale via reverse transcription-polymerase chain reaction(RT-PCR)and deposited in Gen Bank(accession number KY662297).The Boa ZDS gene contains an open reading frame of 1 686 bp that encodes a 561-amino acid protein.Sequence analysis indicates that the ZDS protein is apparently conserved during plant evolution and is most closely related to B.oleracea var.capitata and B.rapa.The promoter sequence of the Boa ZDS gene was predicted to harbor several cis-acting elements that are related to light and phytohormone responses.Semiquantitative RT-PCR analysis showed that Boa ZDS expression varied among different developmental stages and organs.Relative ZDS expression remained stable during germination and seedling stages and rapidly increased at the mature leaf stage.The leaves showed the highest ZDS expression levels compared to the other organs.ZDS expression decreased in all flower tissues during blooming.The fused protein of Boa ZDS was obtained by prokaryotic expression.Heterologous expression of Boa ZDS in Escherichia coli confirmed that Boa ZDS encodes a functionalζ-carotene desaturase that increases β-carotene accumulation in E.coli cells harboring a β-carotene-producing plasmid.The findings of the present study provide a molecular basis for the elucidation of ZDS gene function in Chinese kale. | SUN Bo ZHANG Fen XUE Shengling CHANG Jiaqi ZHENG Aihong JIANG Min MIAO Huiying WANG Qiaomei TANG Haoru | 2018 | Horticultural Plant Journal2018，4，3： | 10 |
| 14 | H_2O_2-induced Leaf Cell Death and the Crosstalk of Reactive Nitric/Oxygen Species显示文摘In plants, the chloroplast is the main reactive oxygen species (ROS) producing site under high light stress. Catalase (CAT), which decomposes hydrogen peroxide (H2O2), is one of the controlling enzymes that maintains leaf redox homeostasis. The catalase mutants with reduced leaf catalase activity from different plant species exhibit an H2O2-induced leaf cell death phenotype. This phenotype was differently affected by light intensity or photoperiod, which may be caused by plant species, leaf redox status or growth conditions. In the rice CAT mutant nitric oxide excess 1 (noe1), higher H2O2 levels induced the generation of nitric oxide (NO) and higher S-nitrosothiol (SNO) levels, suggesting that NO acts as an important endogenous mediator in H2O2-induced leaf cell death. As a free radical, NO could also react with other intracellular and extracellular targets and form a series of related molecules, collectively called reactive nitrogen species (RNS). Recent studies have revealed that both RNS and ROS are important partners in plant leaf cell death. Here, we summarize the recent progress on H2O2-induced leaf cell death and the crosstalk of RNS and ROS signals in the plant hypersensitive response (HR), leaf senescence, and other forms of leaf cell death triggered by diverse environmental conditions. | Yiqin Wang Aihong Lin Gary J.

| 15 | 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 |
| 16 | Morphology and contact mechanics influence adhesive characteristics of Dung Beetle's bristle and Gecko's setae显示文摘Geckos(Gekko gecko)use their hairy setae to adhere on various solid surfaces and dung beetles(Copris ochus Motschulsky)use their hairy bristles to anti-adhere in sticky environments.We study why two hairy systems express a conflict in functions by using SEM,histological approaches and functional experiments.Adhesion models and various parameters were collected and analyzed.Based on the morphological data and functional experimental results carried out by natural and denatured gecko setae and beetle bristles,we first demonstrated that the stiffness along the hair is 1000 to 30000 times that perpendicular to the hair.This stiffness difference is the key factor leading to the two hairy systems' functional differences.Slope of gecko setae reduces contact stiffness,increases contact points and real contact area that results in amazing adhesive abilities.On the other hand,stiff bristles in a beetle have higher contact stiffness,which reduces the real contact area and decreases the adhesion between two contact surfaces.Deformation of gecko setae destroys the hierarchical structure,increases the contact stiffness and results in a decrease of adhesion forces.Similarly,deformation of beetle bristles destroys the erect structure of the hair,interconnects the separated bristles and thus decreases the anti-adhesive functions.These observations inspire us in designing anti-adhesive and adhesive biomimetic | Dai Zhendong Sun Jiurong Yue David Guo Ce Cheng Hong Yu Min Ji Aihong | 2007 | Progress in Natural Science:Materials International2007，17，9： | 8 |

| 18 | Strategy for Use of Rice Blast Resistance Genes in Rice Molecular Breeding显示文摘Rice blast is one of the most destructive diseases affecting rice production worldwide.The development and rational use of resistant varieties has been the most effective and economical measure to control blast.In this review,we summarized the cloning and utilization of rice blast resistance genes,such as Pi1,Pi2,Pi9,Pi54,Pigm and Piz-t.We concluded that three main problems in the current breeding of rice blast resistance are:availability of few R(resistance)genes that confer resistance to both seedling and panicle blast,the resistance effect of pyramided lines is not the result of a simple accumulation of resistance spectrum,and only a few R genes have been successfully used for molecular breeding.Therefore,novel utilization strategies for rice blast R genes in molecular breeding were proposed,such as accurately understanding the utilization of R genes in main modern rice varieties,creating a core resistant germplasm with excellent comprehensive traits,screening and utilizing broadspectrum and durable resistance gene combinations.Lastly,the trends and possible development direction of blast resistance improvement were also discussed,including new genes regulating resistance identified via GWAS(genome-wide association study)and improving rice blast resistance using genetic editing. | XIAO Ning WU Yunyu LI Aihong | 2020 | Rice science2020，27，4： | 7 |
| 19 | Surface mass balance and its climate significance from the coast to Dome A, East Antarctica显示文摘Based on stake measurements conducted along the Chinese Antarctic traverse since Jan.1999,we investigated the characteristics of surface mass balance(SMB)and related climate consequences from Zhongshan Station to Dome A,East Antarctica.Spatial analysis suggests that post-depositional processes have a great impact on surface morphology;thus,the representativeness of a single measurement should be discussed in conjunction with local climate features.The comparison among snow accumulation,ice sheet thickness,surface elevation,and ice velocity indicates that the bedrock topography has an indirect connection with the SMB patterns through controlling the surface topography and local climate.The observation reveals that the Lambert Glacier Basin has been experiencing increasing mass input(4.5%),whereas the inland area has experienced a 6%loss,since 2005.An overall estimation of the SMB along the route is 71.3±44.3 kg m?2 a?1,but the annual and regional variation is considerable.Tendency analysis shows that there are four sections with different SMB patterns as a result of three moisture sources and surface climatic discrepancy in the Antarctic inland.This study is the first to identify four SMB patterns from the coast to the Dome area and should provide a valuable contribution to modeling and remote sensing on a continental scale. | DING MingHu XIAO CunDe LI ChuanJin QIN DaHe JIN Bo SHI GuiTao XIE AiHong CUI XiangBin | 2015 | Science China Earth Sciences2015，58，10： | 7 |
| 20 | Sources, evolution and impacts of EC and OC in snow on sea ice: a measurement study in Barrow, Alaska显示文摘Based on the field measurements in Barrow, Alaska within the period of April-May 2015, we investigate the sources and variations of elemental carbon(EC) and organic carbon(OC) in the surface layer of snowpack on sea ice, and estimate their effects on the sea ice albedo. Results show that the snow OC in Barrow are from natural sources(e.g. terrestrial higher plants and micro-organisms) mainly, as well as biomass burning(e.g. forest fires and straw combustion) as an important part. Both EC and OC can accumulate at the snow surface with snow melt. The variations in EC and OC and liquid water content in the snow layer are well consistent during the snow-melting period. A higher rate of snow melt implied a more efficient enrichment of EC and OC. In the last phase of snow melt, the concentration increased to a maximum of 16.2 ng/g for EC and 128 ng/g for OC, which is ~10 times larger than those before snow melt onset. Except for the dominant influence of melt amplification mechanism, the variation in concentrations of EC and OC could be disturbed by the air temperature fluctuation and snowfall. Our study indicates that the lightabsorbing impurities contributed 1.6%-5.1% to the reduction in sea ice albedo with melt during the measurement period. The significant period oflight-absorbing impurities influencing on sea ice albedo begins with the rapid melting of overlying snow and ends before the melt ponds formed widely, which lasted for about 10 days in Barrow, 2015. | Tingfeng Dou Cunde Xiao Zhiheng Du J.
