| 3 | Evaluation of strategy for analyzing mouse liver plasma membrane proteome显示文摘Plasma membrane (PM) proteome is one of the major subproteomes present in the cell,and is very important in liver function. In the present work, C57 mouse liver PM was purified by density-gradient centrifugation. The purified PM was verified by electron microscope analysis and Western blotting. The results showed that the PM was enriched by more than 20-fold and the contamination of mitochondria was reduced by 2-fold compared with the homogenization fraction. Proteins were separated by 2DE and 1DE, trypsin-digested and submitted to ESI-Q-TOF and MALDI-TOF-TOF mass spectrometry or directly digested in solution and analyzed by LC-ESI ion trap mass spectrometry. In all, 547 non-redundant mouse liver PM proteins were identified, of which 34% contributed to plasma membrane or plasma membrane-related proteins. This study optimized and evaluated the HLPP plasma membrane proteome analysis method and made a systematic analysis on PM proteome. | CHEN Ping ZHANG LiJun LI XuanWen WANG XiE CAO Rui LIU Zhen XIONG JiXian PENG Xia WEI YingJuan YING XingFeng WANG XianChun LIANG SongPing | 2007 | Science China(Life Sciences)2007，50，6： | 1 |
| 4 | Environmental and canopy conditions regulate the forest floor evapotranspiration of larch plantations显示文摘Background:Integrated forest-water management focusing on forest-water coordination is an important way to alleviate water use conflicts among forests and other sectors in vast dryland regions.Forest floor evapotranspiration(FE),which is an important component of forest evapotranspiration,accounts for a large proportion of the water consumed in arid forests.Elucidating how environmental and canopy conditions impact FE has important significance for guiding integrated forest-water management in a changing environment.Methods:The microlysimeter(ML)-measured evapotranspiration(FE_(ML)),reference evapotranspiration(ET_(o)),volumetric soil moisture(VSM),and canopy leaf area index(LAI)were monitored in a Larix principis-rupprechtii plantation located in the semi-humid Liupan Mountains of Northwest China in 2019(June–September)and 2021(May–September).The response functions of the FE coefficient(the ratio of daily FEML to ET_(o))to the individual factors of VSM and LAI were determined using upper boundary lines of scatter diagrams of measured data.The framework of the daily FE(FE_(ML))model was established by multiplying the response functions to individual factors and then calibrated and validated using measured data to assess the FE response to environmental and canopy conditions.Results:(1)The FE coefficient increased first rapidly and then slowly with rising VSM but decreased slowly with rising LAI.(2)The simple daily FE(FE_(ML))model developed by coupling the impacts of ET_(o),LAI,and VSM in this study performed well for predicting FE.(3)The impacts of ET_(o),LAI,and VSM were quantified using the FE(FE_(ML))model,e.g.,at a given VSM,the impact of ETo on FE increased obviously with decreasing LAI;at a given ET_(o),the impact of LAI on FE increased with rising VSM.(4)In the two study years,when directly using the microlysimeter measurement,the real FE on the forest floor was overestimated when the VSM in microlysimeters was above 0.215 but underestimated below 0.215 due to the difference in VSM from the forest floor.Thus,the VSM on the forest floor should be input into the FE model for estimating the real FE on the forest floor.Conclusions:The daily FE of larch plantation is controlled by three main factors of environmental(ET_(o) and VSM)and canopy conditions(LAI).The variation in daily FE on the forest floor can be well estimated using the simple FE model coupling the effects of the three main factors and by inputting the VSM on the forest floor into the model to avoid the errors when directly using the microlysimeter measurement with different VSMs from the forest floor.The developed FE model and suggested prediction approach are helpful to estimate the FE response to changing conditions,and to guide forest management practices when saving water by thinning is required. | Zebin Liu Yanhui Wang Pengtao Yu Lihong Xu Songping Yu | 2022 | Forest Ecosystems2022，9，5： | 1 |

| 11 | 大型水库消落带中西来稗种子耐淹性沿高程梯度的种内分化显示文摘在水文节律稳定、每年蓄水时间很长且水位涨落落差很大的水库中,生长在水库库岸消落带不同高程区域中的植物每年要面对长时间的不同强度的水淹,这种每年发生持续的水淹胁迫可能会导致水库库岸消落带中生长的植物的种子耐淹能力发生种内分化。西来稗(Echinochloa crusgalli var.zelayensis)是在三峡水库消落带中自然生长的优势一年生植物,在三峡水库消落带植被及消落带生态环境保护中发挥着重要作用。本研究的目的在于探究三峡水库消落带中生长的西来稗种子的耐淹能力是否已发生种内分化,以及此分化的发生是否与较弱的种子扩散能力有关。在本研究中,采集来自三峡水库消落带不同高程区域中生长的西来稗种子,在三峡水库即将蓄水时将所有采集的种子放置于三峡水库消落带中4个不同高程位置接受不同深度不同时长的水库蓄水水淹,同时把所有采集的种子也放置于不会被水库蓄水淹没的非消落带河岸上作为对照处理;测定种子在水中的漂浮持续时间和蓄水期间水库水位上涨速度以量化在水库蓄水水位上涨时种子的扩散能力,水库蓄水结束水退后检测放置于水库消落带和非消落带河岸上的种子的种子完好率、种子萌发能力和成苗率。研究结果发现,在经历三峡水库蓄水水淹后,西来稗种子的完好率和最终成苗率随种子母株在消落带中所处的高程的增加而显著降低,表明在三峡水库成库运行七年后,在三峡水库消落带中生长的西来稗的种子耐淹能力已发生了种内分化。三峡水库蓄水水位上涨时西来稗种子在水中较短的漂浮持续时间和水库蓄水时较慢的水位上升速度限制了西来稗种子的水媒传播和扩散距离,从而有利于西来稗种子的耐淹能力发生种内分化。 | Songping Liu Feng Lin Xiaolei Su Qiaoli Ayi Hangang Niu Shaohua Shi Binna Wan Bo Zeng Xiaoping Zhang | 2021 | Journal of Plant Ecology2021，14，1： | 0 |
| 12 | Molecular diversification of antimicrobial peptides from the wolf spider Lycosa sinensis venom based on peptidomic,transcriptomic,and bioinformatic analyses显示文摘The venom of Lycosoidea spiders is a complex multicomponent mixture of neurotoxic pep-tides(main components)and antimicrobial peptides(AMPs)as minor components.In this study,we described the high-throughput identification and analysis of AMPs from Lycosa sinensis venom(named LS-AMPs)using a combination strategy that includes the following three differ-ent analysis approaches:(i)peptidomic analysis,namely reversed-phase high-performance liquid chromatography(RP-HPLC)separation plus top-down sequencing by matrix-assisted laser desorp-tion/ionization time-of-flight mass spectrometry(MS);(i)transcriptomic analysis,namely cDNA library construction plus DNA sequencing;(ii)i)bioinformatic analysis,namely analysis and predic-tion for molecular characters of LS-AMPs by the online biology databases.In total,52 sequences of AMPs were identified from L.sinensis venom,and all AMPs can be categorized into eight different families according to phylogenetic analysis and sequence identity.This is the largest number of AMPs identified from a spider species so far.In the present study,we demonstrated molecular char-acteristics,such as complex precursor,N-and/or C-terminally truncated analogs,and C-terminal amidation of LS-AMPs from L.sinensis venom.This is a preliminary investigation on the molecu-lar diversification of venom-derived AMPs from the wolf spider species(family Lycosidae),and a detailed investigation on the functional diversity of LS-AMPs will be preformed in the future. | Xing Tang Jing Yang Zhigui Duan Liping Jiang Zhonghua Liu Songping Liang | 2020 | Acta Biochimica et Biophysica Sinica2020，52，11： | 0 |
| 13 | Impacts of environmental and canopy conditions on the nighttime sap flow of larch plantations in the Liupan Mountains,China显示文摘Nighttime sap flow(Q_(n))is an important physiological activity under which trees manage drought stress.An in-depth understanding of the characteristics of Q_(n)and its response to environmental and canopy conditions are of significance for arid area forest and water management.This study measured daily sap flow(Q_(s))of a Larix principis-rupprechtii plantation in the Liupan Mountains,northwest China during the 2017-2019 growing seasons,and separated Q_(s)into daytime sap flow(Qd)and Q_(n).Meteorological conditions(reference evapotranspiration,ETref),canopy structure(leaf area index,LAI),and soil moisture(relative soil water content,RSWC)were considered as the main biophysical factors affecting Q_(n).The structural equation model and upper boundary line method determined the effects of compound and single factors on Q_(n)The daily mean Q_(n)values during the growing seasons in 2017,2018,and 2019 were 0.024,0.026,and 0.030 mm d-1,accounting for 6.2,11.2,and 10.1%of Q_(s),respectively.Q_(n)at different canopy development phases(leaf expanding,LG;leaf expanded,LD;and defoliation,DF)over three years was LD>LG>DF.Q_(n)increased with increasing ETref,whereas the ratio of Q_(n)to Q_(s)decreased.Q_(n)did not show regular variation in the three-year growing seasons under different soil moisture conditions.ETrefand LAI mainly controlled Q_(n)by affecting Qd,whereas RSWC had no significant effect on Q_(n).Q_(n)had a positive and linear relationship with LAI and a quadratic relationship with ETref.Both explained 40%of variation in Q_(n)Meteorological and canopy conditions are important factors affecting Q_(n)on the semi-humid study site.The application of the Q_(n)model coupled with the impact of ETrefand LAI furthers understanding of the impacts of climate and forest structure change on Q_(n). | Songping Yu Jianbin Guo Zebin Liu Yanhui Wang Lihong Xu Pengtao Yu Liang He | 2023 | Journal of Forestry Research2023，34，6： | 0 |
| 14 | Leaf Morphology Genes SRL1 and RENL1 Co-Regulate Cellulose Synthesis and Affect Rice Drought Tolerance显示文摘The morphological development of rice(Oryza sativa L.)leaves is closely related to plant architecture,physiological activities,and resistance.However,it is unclear whether there is a co-regulatory relationship between the morphological development of leaves and adaptation to drought environment.In this study,a drought-sensitive,roll-enhanced,and narrow-leaf mutant(renl1)was induced from a semi-rolled leaf mutant(srl1)by ethyl methane sulfonate(EMS),which was obtained from Nipponbare(NPB)through EMS.Map-based cloning and functional validation showed that RENL1 encodes a cellulose synthase,allelic to NRL1/OsCLSD4.The RENL1 mutation resulted in reduced vascular bundles,vesicular cells,cellulose,and hemicellulose contents in cell walls,diminishing the water-holding capacity of leaves.In addition,the root system of the renl1 mutant was poorly developed and its ability to scavenge reactive oxygen species(ROS)was decreased,leading to an increase in ROS after drought stress.Meanwhile,genetic results showed that RENL1 and SRL1 synergistically regulated cell wall components.Our results revealed a theoretical basis for further elucidating the molecular regulation mechanism of cellulose on rice drought tolerance,and provided a new genetic resource for enhancing the synergistic regulation network of plant type and stress resistance,thereby realizing simultaneous improvement of multiple traits in rice. | LIU Dan ZHAO Huibo WANG Zi’an XU Jing LIU Yiting WANG Jiajia CHEN Minmin LIU Xiong ZHANG Zhihai CEN Jiangsu ZHU Li HU Jiang REN Deyong GAO Zhenyu DONG Guojun ZHANG Qiang SHEN Lan LI Qing QIAN Qian HU Songping ZHANG Guangheng | 2024 | Rice science2024，31，1： | 0 |
| 15 | Thermocapillary flow-induced core release from double-emulsion droplets in microchannels显示文摘The use of double emulsions(DEs),which represent colloidal structures composed of droplets nested within droplets,can provide for unparallel droplet manipulation in droplet-based microfluidic technology due to their unique core–shell structures.The controlled release of cores in DEs is of particular interest.However,this process remains poorly explored.In this work,the thermocapillary flow induced by a temperature gradient is used as a driving force to control the core release and the impacts of different linear temperature gradients,core diameters,shell diameter,and core/shell diameter ratios on the thermocapillary flow and core release characteristics of DE droplets consisting of a water-in-n-hexadecane-in-water system within a cylindrical microchannel are investigated.Most of the core and shell diameter conditions considered result in a double-core release process,where the inner droplet volume is partially ejected before the remaining core is rewrapped by the outer droplet,and the remaining inner droplet volume is ejected later during a second core release event.However,relatively small core diameters of 50 and 75μm produce conditions where the full inner droplet volume is ejected during a singlecore release process.In addition,we provide empirical relationships for accurately determining the time at which core release initially occurs under given DE parameters as well as for precisely determining whether the applied conditions will lead to single-or double-core release processes.Therefore,the results of this study provide insights enabling the development of accurate inner droplet release technologies under thermocapillary migration. | Jingyi Qin Zhibin Wang Ying Chen Songping Mo Jian Liu | 2023 | Droplet2023，2，3： | 0 |
| 16 | Microacoustic Imaging Technique for Bulk Microstructure Characterization of Woven CFRC Materials显示文摘In short wavelength case ultrasound propagation through woven carbon fiber-rein-forced composite (CFRC) materials essentially depends on their microstructure.Fiber bundle and weaving ply can be considered as basic structural elements of woven CFRC laminates.These structural units provide effective reflectors when ultra-short impulse high frequency ultrasound impinges on woven laminates.The reflection coefficient R0 achieves level of 3%-15% at ply-ply interface,0.2-0.4 in resin pocket region.This magnitude of reflection coefficient offers reasonable acoustic contrast to see packing,lay-up and resin pockets in woven laminate body by acoustic imaging methods.Microacoustic imaging technique is based on time-resolved echoes from reflections in woven CFRC laminates.A focal system with low aperture angle is used to generate 20-40 probe ultrasonic pulse wave.Its spatial resolution is up to 60mm at 50MHz in woven CFRC laminate.The results presented in this paper demonstrates the possibility and potentiality of characterization of microstrueture of woven CFRC laminates.Packing,lay-up,weaving nature,fiber bundle,resin pocket as well as their topology are exhibited clearly in the acoustic images by using microaeoustic technique. | Liu Songping Guo Enming Liu Feifei Li Legang V.M.Levin Yu S Petronyuk | 2007 | 航空制造技术2007，50，z1： | 0 |
