| 3 | A journey to understand wheat Fusarium head blight resistance in the Chinese wheat landrace Wangshuibai显示文摘Fusarium head blight(FHB) or scab caused by Fusarium graminearum is a major threat to wheat production in China as well as in the world. To combat this disease, multiple efforts have been carried out internationally. In this article, we review our long-time effort in identifying the resistance genes and dissecting the resistance mechanisms by both forward and reverse genetics approaches in the last two decades. We present recent progress in resistance QTL identification, candidate functional gene discovery, marker-assisted improvement of FHB resistant varieties, and findings in investigating association of signal molecules, such as Ca^(++),SA, JA, and ET, with FHB response, with the assistance from rapidly growing genomics platforms. The information will be helpful for designing novel and efficient approaches to curb FHB. | Haiyan Jia Jiyang Zhou Shulin Xue Guoqiang Li Haisheng Yan Congfu Ran Yiduo Zhang Jinxing Shi Li Jia Xin Wang Jing Luo Zhengqiang Ma | 2018 | The Crop Journal2018,6,1: | 24 |
| 4 | A hybrid invisibility cloak based on integration of transparent metasurfaces and zero-index materials显示文摘The invisibility cloak,a long-standing fantastic dream for humans,has become more tangible with the development of metamaterials.Recently,metasurface-based invisibility cloaks have been proposed and realized with significantly reduced thickness and complexity of the cloaking shell.However,the previous scheme is based on reflection-type metasurfaces and is thus limited to reflection geometry.In this work,by integrating the wavefront tailoring functionality of transparent metasurfaces and the wave tunneling functionality of zero-index materials,we have realized a unique type of hybrid invisibility cloak that functions in transmission geometry.The principle is general and applicable to arbitrary shapes.For experimental demonstration,we constructed a rhombic double-layer cloaking shell composed of a highly transparent metasurface and a double-zero medium consisting of dielectric photonic crystals with Dirac cone dispersions.The cloaking effect is verified by both full-wave simulations and microwave experimental results.The principle also reveals exciting possibilities for realizing skin-thick ultrathin cloaking shells in transmission geometry,which can eliminate the need for spatially varying extreme parameters.Our work paves a path for novel optical and electromagnetic devices based on the integration of metasurfaces and metamaterials. | Hongchen Chu Qi Li Bingbing Liu Jie Luo Shulin Sun Zhi Hong Hang Lei Zhou Yun Lai | 2018 | Light(Science & Applications)2018,7,1: | 13 |

| 6 | Controlling angular dispersions in optical metasurfaces显示文摘Although metasurfaces have shown great potential for manipulating light,most previously realized meta-devices suffer from uncontrolled angular dispersions,making them unfavorable for many applications.Here,we propose a general strategy to realize optical metasurfaces with desired angular dispersions based on carefully controlling both the near-field couplings between meta-atoms and the radiation pattern of a single meta-atom.Utilizing such a strategy,we experimentally demonstrate a series of optical meta-devices with predesigned angular dispersions,including two incident-angle-insensitive absorbers,one incident-angle-selective absorber,and one multifunctional meta-polarizer whose functionality changes from a perfect mirror to a half-waveplate as the excitation angle varies.Finally,we design a gradient meta-device using meta-atom arrays with purposely controlled angular dispersions and numerically demonstrate that it can exhibit distinct wavefront-control functionalities when illuminated at different incident angles.Our findings establish a new platform for achieving angle-multiplexed functional meta-devices,significantly expanding the wave-manipulation capabilities of optical metasurfaces. | Xiyue Zhang Qi Li Feifei Liu Meng Qiu Shulin Sun Qiong He Lei Zhou | 2020 | Light(Science & Applications)2020,9,1: | 11 |
| 7 | Efficient manipulations of circularly polarized terahertz waves with transmissive metasurfaces显示文摘The unrestricted control of circularly polarized(CP)terahertz(THz)waves is important in science and applications,but conventional THz devices suffer from issues of bulky size and low efficiency.Although Pancharatnam-Berry(PB)metasurfaces have shown strong capabilities to control CP waves,transmission-mode PB devices realized in the THz regime are less efficient,limiting their applications in practice.Here,based on Jones matrix analysis,we design a trilayer structure(thickness of ~λ/5)and experimentally demonstrate that the structure can serve as a highly efficient transmissive meta-atom(relative efficiency of ~90%)to build PB metadevices for manipulating CP THz waves.Two ultrathin THz metadevices are fabricated and experimentally characterized with a z-scan THz imaging system.The first device can realize a photonic spin Hall effect with an experimentally demonstrated relative efficiency of ~90%,whereas the second device can generate a high-quality background-free CP Bessel beam with measured longitudinal and transverse field patterns that exhibit the nondiffracting characteristics of a Bessel beam.All the experimental results are in excellent agreement with full-wave simulations.Our results pave the way to freely manipulate CP THz beams,laying a solid basis for future applications such as biomolecular control and THz signal transportation. | Min Jia Zhuo Wang Heting Li Xinke Wang Weijie Luo Shulin Sun Yan Zhang Qiong He Lei Zhou | 2019 | Light(Science & Applications)2019,8,1: | 9 |
| 8 | Identification,bioinformatic analysis and expression profiling of candidate mRNA-like non-coding RNAs in Sus scrofa显示文摘Messenger RNA-like non-coding RNAs(mlncRNAs) are a newly identified group of non-coding RNAs(ncRNAs) that may be in-volved in a number of critical cellular events.In this study,93 candidate porcine mlncRNAs were obtained by computational prediction and screening,among which 72 were mapped to the porcine genome.Further analysis of 8 representative candidates revealed that these mlncRNA candidates are not highly conserved among species.Remarkably,one of the candidates,sTF35495,was found to be precursor of a putative porcine microRNA.By RACE PCR,we determined that the full length of sTF35495 was 3 kb.The protein-coding potential of this RNA was tested in silico with no significant finding.Semi-quantitative RT-PCR analysis of the subgroup of 8 candidates revealed two distinct expression profiles and two molecules were further validated by real-time PCR.The predicted pre-microRNA sequence in this study provides a potentially interesting insight into the in vivo function of porcine mlncRNAs and our findings suggest that they play key biological roles in Sus scrofa. | Bang Xiao Xingju Zhang Yong Li Zhonglin Tang Shulin Yang Yulian Mu Wentao Cui Hong Ao Kui Li | 2009 | Journal of Genetics and Genomics2009,36,12: | 7 |
| 9 | Characterization of Air Pollution in Urban Areas of Yangtze River Delta,China显示文摘The hallmark of development in the Yangtze River Delta(YRD) of East China has been sprawling urbanization. However, air pollution is a significant problem in these urban areas. In this paper, we investigated and analyzed the air pollution index(API) in four cities(Shanghai, Nanjing, Hangzhou and Ningbo) in the YRD from 2001 to 2012. We attempted to empirically examine the relationship between meteorological factors and air quality in the urban areas of the YRD. According to the monitoring data, the API in Shanghai, Nanjing, Hangzhou slightly declined and that in Ningbo increased over the study period. We analyzed the inter-annual, seasonal, and monthly variations of API, from which we found that the air quality had different temporal changes in the four cities. It was indicated that air quality was poor in winter and spring and best in summer. Furthermore, different weather conditions affected air quality level. The wind direction was considered as an important and influential factor to air pollution, which has an impact on the accumulating or cleaning processes of pollutants. The air quality was influenced by the different wind directions that varied with seasons and cities. | CHEN Tan DENG Shulin GAO Yu QU Lean LI Manchun CHEN Dong | 2017 | Chinese Geographical Science2017,27,5: | 7 |
| 10 | Molecular Phylogeny Supports the Validity of Polypedates impresus Yang 2008显示文摘The taxonomy of the Asian tree frogs of the Polypedates leucomystax complex, a group of widespread and morphologically similar species, is very controversial. To ascertain the taxonomic status of these species, we investi- gated the historical relationships among representative samples based on ~ 2 kb of nucleotide sequences from the mitochondrial 12S rRNA, tRNAvaline, and 16S rRNA genes. Our phylogeny resolved five well supported lineages(A, B, C, D and E) in the P. leucomystax complex. Polypedates impresus from Yunnan, China, Polypedates cf. mutus and Polypedates cf. megacephalus from Guangxi and Yunnan, China, and Laos constructed Clade C, which is monophyletic. In order to recognize the unique position of this clade, we considered P. impresus in Clade C as a valid species. Following our phylogeny, Chinese Polypedates, corresponding to the other four clades, should include four species: P. mutus(Clade A); P. braueri(Clade B); P. impresus(Clade C) and P. megacephalus(Clade D). P. leucomystax(Clade E) is mainly distributed in the Malaysia, Indonesia and Philippines. | Shulin PAN Ningxin DANG Jishan WANG Yitao ZHENG Dingqi RAO Jiatang LI | 2013 | Asian Herpetological Research2013,4,2: | 6 |
| 11 | Label-free fiber nanograting sensor for real-time in situ early monitoring of cellular apoptosis显示文摘The achievement of functional nanomodules for subcellular label-free measurement has long been pursued in order to fully understand cellular functions.Here,a compact label-free nanosensor based on a fiber taper and zinc oxide nanogratings is designed and applied for the early monitoring of apoptosis in individual living cells.Because of its nanoscale dimensions,mechanical flexibility,and minimal cytotoxicity to cells,the sensing module can be loaded in cells for long term in situ tracking with high sensitivity.A gradual increase in the nuclear refractive index during the apoptosis process is observed,revealing the increase in molecular density and the decrease in cell volume.The strategy used in our study not only contributes to the understanding of internal environmental variations during cellular apoptosis but also provides a new platform for nonfluorescent fiber devices for investigation of cellular events and understanding fundamental cell biochemical engineering. | Danran Li Nina Wang Tianyang Zhang Guangxing Wu Yifeng Xiong Qianqian Du Yunfei Tian Weiwei Zhao Jiandong Ye Shulin Gu Yanqing Lu Dechen Jiang Fei Xu | 2022 | Advanced Photonics2022,4,1: | 5 |
| 12 | Engineering an enthesis-like graft for rotator cuff repair:An approach to fabricate highly biomimetic scaffold capable of zone-specifically releasing stem cell differentiation inducers显示文摘Rotator cuff(RC)attaches to humerus across a triphasic yet continuous tissue zones(bone-fibrocartilage-tendon),termed“enthesis”.Regrettably,rapid and functional enthesis regeneration is challenging after RC tear.The existing grafts bioengineered for RC repair are insufficient,as they were engineered by a scaffold that did not mimic normal enthesis in morphology,composition,and tensile property,meanwhile cannot simultaneously stimulate the formation of bone-fibrocartilage-tendon tissues.Herein,an optimized decellularization approach based on a vacuum aspiration device(VAD)was developed to fabricate a book-shaped decellularized enthesis matrix(O-BDEM).Then,three recombinant growth factors(CBP-GFs)capable of binding collagen were synthesized by fusing a collagen-binding peptide(CBP)into the N-terminal of BMP-2,TGF-β3,or GDF-7,and zone-specifically tethered to the collagen of O-BDEM to fabricate a novel scaffold(CBP-GFs/O-BDEM)satisfying the above-mentioned requirements.After ensuring the low immunogenicity of CBP-GFs/O-BDEM by a novel single-cell mass cytometry in a mouse model,we interleaved urine-derived stem cell-sheets into this CBP-GFs/O-BDEM to bioengineer an enthesis-like graft.Its high-performance on regenerating enthesis was determined in a canine model.These findings indicate this CBP-GFs/O-BDEM may be an excellent scaffold for constructing enthesis-like graft to patch large/massive RC tears,and provide breakthroughs in fabricating graded interfacial tissue. | Can Chen Qiang Shi Muzhi Li Yang Chen Tao Zhang Yan Xu Yunjie Liao Shulin Ding Zhanwen Wang Xing Li Chunfeng Zhao Lunquan Sun Jianzhong Hu Hongbin Lu | 2022 | Bioactive Materials2022,7,10: | 4 |

| 14 | A new type of ERGIC–ERES membrane contact mediated by TMED9 and SEC12 is required for autophagosome biogenesis显示文摘Under stress,the endomembrane system undergoes reorganization to support autophagosome biogenesis,which is a central step in autophagy.How the endomembrane system remodels has been poorly understood.Here we identify a new type of membrane contact formed between the ER-Golgi intermediate compartment(ERGIC)and the ER-exit site(ERES)in the ER-Golgi system,which is essential for promoting autophagosome biogenesis induced by different stress stimuli.The ERGIC-ERES contact is established by the interaction between TMED9 and SEC12 which generates a short distance opposition(as close as 2-5 nm)between the two compartments.The tight membrane contact allows the ERES-located SEC12 to transactivate COPII assembly on the ERGIC.In addition,a portion of SEC12 also relocates to the ERGIC.Through both mechanisms,the ERGIC-ERES contact promotes formation of the ERGIC-derived COPII vesicle,a membrane precursor of the autophagosome.The ERGIC-ERES contact is physically and functionally different from the TFG-mediated ERGIC-ERES adjunction involved in secretory protein transport,and therefore defines a unique endomembrane structure generated upon stress conditions for autophagic membrane formation. | Shulin Li Rui Yan Jialu Xu Shiqun Zhao Xinyu Ma Qiming Sun Min Zhang Ying Li Jun-Jie Gogo Liu Liangyi Chen Sai Li Ke Xu Liang Ge | 2022 | Cell Research2022,32,2: | 3 |

| 16 | Palm oil protectsα-linolenic acid from rumen biohydrogenation and muscle oxidation in cashmere goat kids显示文摘Background:In ruminants,dietary C18:3n-3 can be lost through biohydrogenation in the rumen;and C18:3n-3 that by-passes the rumen still can be lost through oxidation in muscle,theoretically reducing the deposition of C18:3n-3,the substrate for synthesis of poly-unsaturated fatty acids(n-3 LCPUFA)in muscle.In vitro studies have shown that rumen hydrogenation of C18:3n-3 is reduced by supplementation with palm oil(rich in cis-9 C18:1).In addition,in hepatocytes,studies with neonatal rats have shown that cis-9 C18:1 inhibits the oxidation of C18:3n-3.It therefore seems likely that palm oil could reduce both rumen biohydrogenation of C18:3n-3 and muscle oxidation of C18:3n-3.The present experiment tested whether the addition of palm oil to a linseed oil supplement for goat kids would prevent the losses of C18:3n-3 and thus improve the FA composition in two muscles,Longissimus dorsi and Biceps femoris.To investigate the processes involved,we studied the rumen bacterial communities and measured the mRNA expression of genes related to lipid metabolism in Longissimus dorsi.Sixty 4-month-old castrated male Albas white cashmere kids were randomly allocated among three dietary treatments.All three diets contained the same ingredients in the same proportions,but differed in their fat additives:palm oil(PMO),linseed oil(LSO)or mixed oil(MIX;2 parts linseed oil plus 1 part palm oil on a weight basis).Results:Compared with the LSO diet,the MIX diet decreased the relative abuandance of Pseudobutyrivibrio,a bacterial species that is positively related to the proportional loss rate of dietary C18:3n-3 and that has been reported to generate the ATP required for biohydrogenation(reflecting a decrease in the abundance of rumen bacteria that hydrogenate C18:3n-3 in MIX kids).In muscle,the MIX diet increased concentrations of C18:3n-3,C20:5n-3,C22:6n-3,and n-3 LCPUFA,and thus decreased the n-6/n-3 ratio;decreased the mRNA expression of CPT1β(a gene associated with fatty acid oxidation)and increased the mRNA expression of FADS1 and FADS2(genes associated with n-3 LCPUFA synthesis),compared with the LSO diet.Interestingly,compared to Longissimus dorsi,Biceps femoris had greater concentrations of PUFA,greater ratios of unsaturated fatty acids/saturated fatty acids(U/S),and poly-unsaturated fatty acids/saturated fatty acids(P/S),but a lesser concentration of saturated fatty acids(SFA).Conclusions:In cashmere goat kids,a combination of linseed and palm oils in the diet increases the muscle concentration of n-3 LCPUFA,apparently by decreasing the relative abundance of rumen bacteria that are positively related to the proportional loss rate of dietary C18:3n-3,by inhibiting mRNA expression of genes related to C18:3n-3 oxidation in muscle,and by up-regulating mRNA expression of genes related to n-3 LCPUFA synthesis in muscle,especially in Longissimus dorsi. | Xue Wang Graeme B.Martin Qi Wen Shulin Liu Yinhao Li Binlin Shi Xiaoyu Guo Yanli Zhao Yangdong Guo Sumei Yan | 2021 | Journal of Animal Science and Biotechnology2021,12,2: | 3 |
| 17 | Differentiation of fetal pancreatic stem cells into neuron-like and islet-like cells in vitro显示文摘Pancreatic stem cells were isolated and cultured from aborted human fetal pancreases of gestational age 14-20 weeks. They were seeded at a density of 1 × 104 in serum-free media for differentiation into neuron-like cells, expressing β-tubulin III and glial fibrillary acidic protein. These neuron-like cells displayed a synapse-like morphology and appeared to form a neuronal network. Pancreatic stem cells were also seeded at a density of 1 × 105 for differentiation into islet-like cells, expressing insulin and glucagon, with an islet-like morphology. These cells had glucose-stimulated secretion of human insulin and C-peptide. Results suggest that pancreatic stem cells can be differentiated into neuron-like and islet-like cells. | Xiufeng Hua Yanwei Wang Peiwen Lian Shouxin Zhang Jianyuan Li Haiyan Wang Shulin Chen Wei Gao | 2012 | Neural Regeneration Research2012,7,7: | 3 |
| 18 | Dry modification of electrode materials by roller vibration milling at room temperature显示文摘For the first time dry roller vibration milling at room temperature was used to prepare active carbon(AC)nano-particles and to modify MnO2 powder as electrode materials.In 30 min AC was milled to a mean particle size of 30–50 nm with increased crystallinity and higher specific surface area,predominantly mesoporous and with improved pore diameter distribution.Then,AC nano-particles were incorporated with MnO2 or bismuth-doped MnO2 nano-particles synthesized by sol–gel methods to prepare nano-composite electrode materials for studying their electrochemical performance.The AC nano-particles combined with 10 wt.%bismuth-doped MnO2 nano-particles were found to possess excellent electrochemical property with specific capacitance up to 308 F/g and without obvious attenuation with increasing current.Our method seems to open a new way to improve AC based electrode materials used for clean energy such as super capacitors. | Shengjuan Li Shulin Wang Bo Xu | 2008 | Particuology2008,6,5: | 2 |

| 20 | Atomic-scale structural and chemical evolution of Li3V2(PO4)3 cathode cycled at high voltage window显示文摘Here,by using atomically resolved scanning transmission electron microscopy and electron energy loss spectroscopy,we investigate the structural and chemical evolution of Li3V2(PO4)3 (LVP) upon the high-voltage window (3.0-4.8 V).We find that the valence of vanadium gradually increases towards the core corresponding to the formation of electrochemically inactive Li3-xV2(PO4)3 (L3-xVP) phases.These Li-deficient phases exhibit structure distortion with superstructure stripes,likely caused by the migration of the vanadium,which can slow down the lithium ion diffusion or even block the diffusion channels.Such kinetic limitations lead to the formation of Li-deficient phase along with capacity loss.Thus,the LVP continuously losses of electrochemical activity and Li-deficient phases gradually grow from the particle core towards the surface during cycling.After 500 cycles,the thickness of active LVP layer decreases to be - 5-20 nm.Moreover,the micromorphology and chemical composition of solid electrolyte interphase (SEI) have been investigated,indicating the thick SEI film also contributes to the capacity loss.The present work reveals the structural and chemical evolution in the cycled electrode materials at an atomic scale,which is essential to understand the voltage fading and capacity decaying of LVP cathode. | Shulin Chen Jian Zou Yuehui Li Ning Li Mei Wu Jinghuang Lin Jingmin Zhang Jian Cao Jicai Feng Xiaobin Niu Jianming Bai Junlei Qi Peng Gao Liping Wang Hong Li | 2019 | Nano Research2019,12,7: | 1 |
