| 1 | Phosphorus recovery from biogas fermentation liquid by Ca-Mg loaded biochar显示文摘Shortage in phosphorus(P) resources and P wastewater pollution is considered as a serious problem worldwide. The application of modified biochar for P recovery from wastewater and reuse of recovered P as agricultural fertilizer is a preferred process. This work aims to develop a calcium and magnesium loaded biochar(Ca–Mg/biochar) application for P recovery from biogas fermentation liquid. The physico-chemical characterization, adsorption efficiency, adsorption selectivity, and postsorption availability of Ca-Mg/biochar were investigated. The synthesized Ca–Mg/biochar was rich in organic functional groups and in Ca O and Mg O nanoparticles. With the increase in synthesis temperature, the yield decreased, C content increased, H content decreased, N content remained the same basically, and BET surface area increased. The P adsorption of Ca–Mg/biochar could be accelerated by nano-Ca O and nano-Mg O particles and reached equilibrium after 360 min.The process was endothermic, spontaneous, and showed an increase in the disorder of the solid–liquid interface. Moreover, it could be fitted by the Freundlich model. The maximum P adsorption amounts were 294.22, 315.33, and 326.63 mg/g. The P adsorption selectivity of Ca–Mg/biochar could not be significantly influenced by the typical p H level of biogas fermentation liquid. The nano-Ca O and nano-Mg O particles of Ca–Mg/biochar could reduce the negative interaction effects of coexisting ions. The P releasing amounts of postsorption Ca–Mg/biochar were in the order of Ca–Mg/B600 > Ca–Mg/B450 > Ca–Mg/B300. Results revealed that postsorption Ca–Mg/biochar can continually release P and is more suitable for an acid environment. | Ci Fang Tao Zhang Ping Li Rongfeng Jiang Shubiao Wu Haiyu Nie Yingcai Wang | 2015 | Journal of Environmental Sciences2015，27，3： | 21 |

| 3 | Functional traits of tree species with phylogenetic signal co-vary with environmental niches in two large forest dynamics plots显示文摘Aims While using phylogenetic and functional approaches to test the mechanisms of community assembly,functional traits often act as the proxy of niches.However,there is little detailed knowledge regarding the correlation between functional traits of tree species and their niches in local communities.We suggest that the co-varying correlation between functional traits and niches should be the premise for using phylogenetic and functional approaches to test mechanisms of community assembly.Using functional traits,phylogenetic and environmental data,this study aims to answer the questions:(i)within local communities,do functional traits of co-occurring species covary with their environmental niches at the species level?and(ii)what is the key ecological process underlying community assembly in Xishuangbanna and Ailaoshan forest dynamic plots(FDPs)?Methods We measured seven functional traits of 229 and 36 common species in Xishuangbanna and Ailaoshan FDPs in tropical and subtropical China,respectively.We also quantified the environmental niches for these species based on conditional probability.We then analyzed the correlations between functional traits and environmental niches using phylogenetic independent contrasts.After examining phylogenetic signals of functional traits using Pagel’sλ,we quantified the phylogenetic and functional dispersion along environmental gradients within local tree communities.Important Findings For target species,functional traits do co-vary with environmental niches at the species level in both of the FDPs,supporting that functional traits can be used as a proxy for local-scale environmental niches.Functional traits show significant phylogenetic signals in both of the FDPs.We found that the phylogenetic and functional dispersion were significantly clustered along topographical gradients in the Ailaoshan FDP but overdispersion in the Xishuangbanna FDP.These patterns of phylogenetic and functional dispersion suggest that environmental filtering plays a key role in structuring local tree assemblages in Ailaoshan FDP,while competition exclusion plays a key role in Xishuangbanna FDP. | Jie Yang Xiuqin Ci Mengmeng Lu Guocheng Zhang Min Cao Jie Li Luxiang Lin | 2014 | Journal of Plant Ecology2014，7，2： | 16 |
| 4 | COVID-19: Challenges to GIS with Big Data显示文摘The outbreak of the 2019 novel coronavirus disease(COVID-19)has caused more than 100,000 people infected and thousands of deaths.Currently,the number of infections and deaths is still increasing rapidly.COVID-19 seriously threatens human health,production,life,social functioning and international relations.In the fight against COVID-19,Geographic Information Systems(GIS)and big data technologies have played an important role in many aspects,including the rapid aggregation of multi-source big data,rapid visualization of epidemic information,spatial tracking of confirmed cases,prediction of regional transmission,spatial segmentation of the epidemic risk and prevention level,balancing and management of the supply and demand of material resources,and socialemotional guidance and panic elimination,which provided solid spatial information support for decision-making,measures formulation,and effectiveness assessment of COVID-19 prevention and control.GIS has developed and matured relatively quickly and has a complete technological route for data preparation,platform construction,model construction,and map production.However,for the struggle against the widespread epidemic,the main challenge is finding strategies to adjust traditional technical methods and improve speed and accuracy of information provision for social management.At the data level,in the era of big data,data no longer come mainly from the government but are gathered from more diverse enterprises.As a result,the use of GIS faces difficulties in data acquisition and the integration of heterogeneous data,which requires governments,businesses,and academic institutions to jointly promote the formulation of relevant policies.At the technical level,spatial analysis methods for big data are in the ascendancy.Currently and for a long time in the future,the development of GIS should be strengthened to form a data-driven system for rapid knowledge acquisition,which signifies ts that GIS should be used to reinforce the social operation parameterization of models and methods,especially when providing support for social management. | Chenghu Zhou Fenzhen Su Tao Pei An Zhang Yunyan Du Bin Luo Zhidong Cao Juanle Wang Wen Yuan Yunqiang Zhu Ci Song Jie Chen Jun Xu Fujia Li Ting Ma Lili Jiang Fengqin Yan Jiawei Yi Yunfeng Hu Yilan Liao Han Xiao | 2020 | Geography and Sustainability2020，1，1： | 13 |

| 6 | Cortical plasticity and nerve regeneration after peripheral nerve injury显示文摘With the development of neuroscience, substantial advances have been achieved in peripheral nerve regeneration over the past decades. However, peripheral nerve injury remains a critical public health problem because of the subsequent impairment or absence of sensorimotor function. Uncomfortable complications of peripheral nerve injury, such as chronic pain, can also cause problems for families and society. A number of studies have demonstrated that the proper functioning of the nervous system depends not only on a complete connection from the central nervous system to the surrounding targets at an anatomical level, but also on the continuous bilateral communication between the two. After peripheral nerve injury, the interruption of afferent and efferent signals can cause complex pathophysiological changes, including neurochemical alterations, modifications in the adaptability of excitatory and inhibitory neurons, and the reorganization of somatosensory and motor regions. This review discusses the close relationship between the cerebral cortex and peripheral nerves. We also focus on common therapies for peripheral nerve injury and summarize their potential mechanisms in relation to cortical plasticity. It has been suggested that cortical plasticity may be important for improving functional recovery after peripheral nerve damage. Further understanding of the potential common mechanisms between cortical reorganization and nerve injury will help to elucidate the pathophysiological processes of nerve injury, and may allow for the reduction of adverse consequences during peripheral nerve injury recovery. We also review the role that regulating reorganization mechanisms plays in functional recovery, and conclude with a suggestion to target cortical plasticity along with therapeutic interventions to promote peripheral nerve injury recovery. | Ci Li Song-Yang Liu Wei Pi Pei-Xun Zhang | 2021 | Neural Regeneration Research2021，16，8： | 12 |
| 7 | Genetic characterization and linkage disequilibrium mapping of resistance to gray leaf spot in maize(Zea mays L.)显示文摘Gray leaf spot(GLS),caused by Cercospora zeae-maydis,is an important foliar disease of maize(Zea mays L.)worldwide,resistance to which is controlled by multiple quantitative trait loci(QTL).To gain insights into the genetic architecture underlying the resistance to this disease,an association mapping population consisting of 161 inbred lines was evaluated for resistance to GLS in a plant pathology nursery at Shenyang in 2010 and 2011.Subsequently,a genome-wide association study,using 41,101 single-nucleotide polymorphisms(SNPs),identified 51 SNPs significantly(P<0.001)associated with GLS resistance,which could be converted into 31 QTL.In addition,three candidate genes related to plant defense were identified,including nucleotidebinding-site/leucine-rich repeat,receptor-like kinase genes similar to those involved in basal defense.Two genic SNPs,PZE-103142893 and PZE-109119001,associated with GLS resistance in chromosome bins 3.07 and 9.07,can be used for marker-assisted selection(MAS)of GLS resistance.These results provide an important resource for developing molecular markers closely linked with the target trait,enhancing breeding efficiency. | Liyu Shi Xiangling Lv Jianfeng Weng Hanyong Zhu Changlin Liu Zhuanfang Hao Yu Zhou Degui Zhang Mingshun Li Xiaoke Ci Xinhai Li Shihuang Zhang | 2014 | The Crop Journal2014，2，Z1： | 9 |
| 8 | Confining MOF-derived SnSe nanoplatelets in nitrogen-doped graphene cages via direct CVD for durable sodium ion storage显示文摘Tin-based compounds are deemed as suitable anode candidates affording promising sodium-ion storages for rechargeable batteries andhybrid capacitors.However,synergistically tailoring the electrical conductivity and structural stability of tin-based anodes to attain durablesodium-ion storages remains challenging to date for its practical applications.Herein,metal-organic framework(MOF)derived SnSe/C wrappedwithin nitrogen-doped graphene(NG@SnSe/C)is designed targeting durable sodium-ion storage.NG@SnSe/C possesses favorable electricalconductivity and structure stability due to the'inner'carbon framework from the MOF thermal treatment and'outer'graphitic cage from thedirect chemical vapor deposition synthesis.Consequently,NG@SnSe/C electrode can obtain a high reversible capacity of 650 mAh·g^-1 at 0.05 A·g^1,a favorable rate performance of 287.8 mAh·g^1 at 5 A·g^1 and a superior cycle stability with a negligible capacity decay of 0.016%percycle over 3,200 cycles at 0.4 A·g^1.Theoretical calculations reveal that the nitrogen-doping in graphene can stabilize the NG@SnSe/Cstructure and improve the electrical conductivity.The reversible Na-ion storage mechanism of SnSe is further investigated by in-situ X-raydiffraction/ex-s/tu transmission electron microscopy.Furthermore,assembled sodium-ion hybrid capacitor full-cells comprising our NG@SnSe/Canode and an active carbon cathode harvest a high energy/power density of 115.5 Wh·kg^-1/5,742 W·kg^-1,holding promise for next-generationen ergy storages. | Chen Lu Zhenzhu Li Zhou Xia Haina Ci Jingsheng Cai Yingze Song Lianghao Yu Wanjian Yin Shixue Dou Jingyu Sun Zhongfan Liu | 2019 | Nano Research2019，12，12： | 7 |
| 9 | Composite solid electrolyte of Na3PS4-PEO for all-solid-state SnS2/Na batteries with excellent interfacial compatibility between electrolyte and Na metal显示文摘High ionic conductivity and superior interfacial stability of solid electrolytes at the electrodes are crucial factors for high-performance all-solid-state sodium batteries. Herein, a composite solid electrolyte Na3PS4-polyethylene oxide is synthesized by the solution-phase reaction method with an improved ionic conductivity up to 9.4 × 10-5 S/cm at room temperature. Moreover, polyethylene oxide polymer layer is wrapped homogeneously on the surface of Na3PS4 particles, which could effectively avoid the direct contact between Na3PS4 electrolyte and sodium metal, thus alleviate their side reactions. We demonstrate that all-solid-state battery SnS2/Na with the composite solid electrolyte Na3PS4-polyethylene oxide delivers an enhanced electrochemical performance with 230 m Ah/g after 40 cycles. | Xiaoyan Xu Yuanyuan Li Jun Cheng Guangmei Hou Xiangkun Nie Qing Ai Linna Dai Jinkui Feng Lijie Ci | 2020 | Journal of Energy Chemistry2020，29，2： | 7 |
| 10 | Nitrogen-doped graphene nanosheets as high efficient catalysts for oxygen reduction reaction显示文摘It is of great significance in exploring alternative catalysts to platinum (Pt)-based materials for oxygen reduction reaction (ORR),because this reaction is invariably involved in various fuel cells and metal-air batteries.We herein reported the nitrogen doped graphene nanosheets (NGNSs) with pore volume of as high as 3.42 m 3 /g and investigated their potential application as ORR catalysts,it was demonstrated the NGNSs featured high activity,improved kinetics and excellent long-term stability for ORR.The NGNSs were successfully used as cathode catalysts of microbial fuel cells (MFCs) and performed even better than the commercial Pt/C (Pt 10%) catalysts at the maximum power output. | CI SuQin WU YongMin ZOU JianPing TANG LongHua LUO ShengLian LI JingHong WEN ZhenHai | 2012 | Chinese Science Bulletin2012，57，23： | 7 |
| 11 | Microstructure and tensile properties of DD32 single crystal Ni-base superalloy repaired by laser metal forming显示文摘In this work,the microstructure and tensile properties of DD32 single-crystal(SC)superalloy repaired by laser metal forming(LMF)using pulsed laser have been studied in detail.The microstructures of the deposited samples and the tensile-ruptured samples were characterized by optical microscopy(OM),transmission electron microscope(TEM)and scanning electron microscope(SEM).Due to high cooling rate,the primary dendrite spacing in the deposited area(17.2μm)was apparently smaller than that in the substrate area(307μm),and the carbides in the deposited samples were also smaller compared with that in the substrate area.The formation of(γ+γ’)eutectic in the initial layer of repaired SC was inhibited because of the high cooling rate.As the deposition proceeded,the cooling rate decreased,and the(γ+γ’)eutectic increased gradually.The(γ+γ’)eutectic at heat-affected zone(HAZ)in the molten pool dissolved partly because of the high temperature at HAZ,but there were still residual eutectics.Tensile test results showed that tensile behavior of repaired SC at different temperatures was closely related to the MC carbides,solidification porosity,γ’phase,and(γ+γ’)eutectic.At moderate temperature,the samples tested fractured preferentially at the substrate area due to the fragmentation of the coarse MC carbide in the substrate area.At elevated temperature,the(γ+γ’)eutectic and solidification porosity in the deposited area became the source of cracks,which deteriorated the high-temperature properties and made the samples rupture at the deposited area preferentially. | Shiwei Ci Jingjing Liang Jinguo Li Yizhou Zhou Xiaofeng Sun | 2020 | Journal of Materials Science & Technology2020，42，10： | 6 |
| 12 | Factors related to improved American Spinal Injury Association grade of acute traumatic spinal cord injury显示文摘BACKGROUND Acute traumatic spinal cord injury(ATSCI)usually results in disability,yet data on contemporary national trends of ATSCI incidence are limited.AIM To provide a systematic and basic theoretical basis for improving the treatment of acute spinal cord injury.METHODS Data from the Peking University Third Hospital Inpatient Sample databases were analyzed.A total of 304 patients with ATSCI were included from 2012 to 2017.The epidemiological data,treatment,complications and clinical outcomes of these patients were reviewed.RESULTS Of the 304 patients,257(84.5%)were male,and 75%of the patients were 55 years old or younger.135 patients had improved follow-up American Spinal Injury Association(ASIA)grades(44.4%).Only 14 patients with ASIA grade A improved.A statistically significant difference in prognosis between patients who underwent surgery within 72 h and those who underwent surgery after 72 h was observed(P<0.05).Surgery within 72 h resulted in better prognosis.The Steroid group and the Non-Steroid group showed a significant difference in outcome among patients with ASIA grades A and B(P<0.05).Patients with pneumonia had a poorer prognosis than patients without pneumonia(P<0.05).Surgery within 72 h resulted in better prognosis.CONCLUSION This study found that there was no significant difference in hospitalization time and prognosis between the Steroid group and the Non-Steroid group,but the patients with severe spinal cord injury(ASIA grades A and B)who underwent surgery combined with steroid therapy had a better prognosis than those who underwent surgery alone.The disastrous consequences of ATSCI and lack of consensus on the management strategy are obvious.Further improvements in treatment planns are needed in order to obtain more reliable functional outcomes. | Ci Tian Yang Lv Shu Li Dai-Dai Wang Yi Bai Fang Zhou Qing-Bian Ma | 2020 | World Journal of Clinical Cases2020，8，20： | 5 |
| 13 | Effects of structure and sur-face properties on carbon nanotubes' hydrogen storage characteristics显示文摘Hydrogen adsorption experiments were carried out in special stainless steel vessels at room temperature (298K) and under 10 MPa using self-synthesized multi-walled carbon nanotubes. In the experiments, carbon nanotubessynthesized by the seeded catalyst method were pretreatedby being soaked in chemical reagents or annealed at hightemperature before they were used to adsorb hydrogen, but their capacity for hydrogen storage was still poor. Carbonnanotubes synthesized by the floating catalyst method were found to be able to adsorb more hydrogen. They have ahydrogen storage capacity of over 4% after they wereannealed at high temperatures, which suggested that theycould be used as a promising material for hydrogen storage. | LI Xuesong ZHU Hongwei CI Lijie XU Cailu MAO Zongqiang WEI Bingqing LIANG Ji WU Dehai | 2001 | Chinese Science Bulletin2001，46，16： | 5 |
| 14 | Tuning F-doped degree of rGO:Restraining corrosion-promotion activity of EP/rGO nanocomposite coating显示文摘Given that graphene features high electrical conductivity,it is a kind of material with corrosion-promotion activity.This study aimed to inhibit the corrosion-promotion activity of graphene in coatings.Here,we report an exciting application of epoxy matrix(EP)/F-doped reduced graphene oxide(rGO)coatings for the long-term corrosion protection of steel.The synthesized F-doped rGO(FG)did not reduce the utilization of rGO by a wide margin and possessed distinctive electrically insulating nature.The electrical conductivity of rGO was approximately 1500 S/m,whereas those of FG-1,FG-2 and FG-3 were 1.17,5.217×10^−2 and 3.643×10^-11 S/m,respectively.FG and rGO were then dispersed into epoxy coatings.The chemical structures of rGO and FG were investigated by transmission electron microscopy(TEM),scanning probe microscopy(SPM),X-ray photoelectron spectroscopy(XPS),Fourier-transform infrared spectroscopy(FTIR),and X-ray diffraction(XRD).EP/FG coatings exhibited outstanding corrosion protection in comparison with blank EP and EP/rGO coatings mainly because the corrosion-promotion effect of rGO was eliminated.The anticorrosion ability of EP/FG coatingswasimproved with increased F-doped degree of FG.In addition,electrochemical impendance spectroscopy(EIS)results indicated that the Rc values of EP/FG-2 and EP/FG-3 were four orders of magnitude higher than those of EP/rGO in diluent NaCl solution(3.5 wt.%)after immersion for 90 days. | Lu Shen Yong Li Wenjie Zhao Kui Wang Xiaojing Ci Yangmin Wu Gang Liu Chao Liu Zhiwen Fang | 2020 | Journal of Materials Science & Technology2020，44，9： | 5 |
| 15 | Tribological and anti-corrosion performance of epoxy resin composite coatings reinforced with differently sized cubic boron nitride(CBN)particles显示文摘A series of high solid content(30 wt%)epoxy resin(EP)composite coatings reinforced with differently sized cubic boron nitride(CBN)particles were fabricated successfully on 304 L stainless steel.Polydopamine(PDA)was used to improve the dispersibility of CBN particles in EP.The structural and morphological features of the CBN particles and the composite coatings were characterized by Raman spectroscopy,scanning electron microscopy(SEM),and transmission electron microscopy(TEM).Moreover,a UMT-3 tribometer and surface profiler were used to investigate the tribological behaviors of the as-prepared composite coatings.Electrochemical impedance spectroscopy(EIS)and Tafel analysis were used to investigate the coatings'anti-corrosion performance.The results demonstrated that the CBN fillers could effectively enhance the tribological and anti-corrosion properties of the EP composite coatings.In addition,when the additive proportion of the microsized(5μm)and nanosized(550 nm)CBN particles was 1:1,the tribological property of the EP composite coatings was optimal for dry sliding,which was attributed to the load carrying capability of the microsized CBN particles and the toughening effect of the nanosized CBN particles.However,when the additive proportion of the microsized and nanosized CBN particles was 2:1,the tribology and corrosion resistance performance were optimal in seawater conditions.We ascribed this to the load-carrying capacity of the microparticles,which played a more important role under the seawater lubrication condition,and the more compact structure,which improved the electrolyte barrier ability for the composite coatings. | Zhiping HUANG Wenjie ZHAO Wenchao ZHAO Xiaojing CI Wentao LI | 2021 | Friction2021，9，1： | 5 |
| 16 | Cardiac arrhythmias and cardiac arrest related to mushroom poisoning: A case report显示文摘BACKGROUND Mushroom exposure is a global health issue.The manifestations of mushroom poisoning (MP) may vary.Some species have been reported as rhabdomyolytic,hallucinogenic,or gastrointestinal poisons.Critical or even fatal MPs are mostly attributable to Amanita phalloides,with the development of severe liver or renal failure.Myocardial injury and even cases mimicking ST-segment elevation myocardial infarction (STEMI) have been previously reported,while cardiac arrhythmia or cardiac arrest is not commonly seen.CASE SUMMARY We report a 68-year-old woman with MP who suffered from delirium,seizure,long QT syndrome on electrocardiogram (ECG),severe cardiac arrhythmias of multiple origins,and cardiac arrest.She was intubated and put on blood perfusion.Her kidney and liver functions were intact;creatine kinase-MB was mildly elevated,and then fell within normal range during her hospital stay.We sent the mushrooms she left for translation elongation factor subunit 1α,ribosomal RNA gene sequence,and internal transcribed spacer sequence analyses.There were four kinds of mushrooms identified,two of which were found to be toxic.CONCLUSION This is the first time that we found cardiac toxicity caused by Panaeolus subbalteatus and Conocybe lactea,which were believed to be toxic to the liver,kidney,and brain.We suggest that intensive monitoring and ECG follow-up are essential to diagnose prolonged QT interval and different forms of tachycardia in MP patients,even without the development of severe liver or renal failure.The mechanisms need to be further investigated and clarified based on animal experiments and molecular signal pathways. | Shu Li Qing-Bian Ma Ci Tian Hong-Xia Ge Yang Liang Zhi-Guo Guo Cheng-Duo Zhang Bei Yao Jia-Ning Geng Fran Riley | 2019 | World Journal of Clinical Cases2019，7，16： | 4 |

| 18 | Contrasting effects of space and environment on functional and phylogenetic dissimilarity in a tropical forest显示文摘Aims The evolutionary history and functional traits of species can illumi-nate ecological processes supporting coexistence in diverse forest communities.However,little has been done in decoupling the rela-tive importance of these mechanisms on the turnover of phylogenetic and functional characteristics across life stages and spatial scales.Therefore,this study aims to estimate the contribution of environment and dispersal on the turnover of phylogenetic and functional diversity across life stages and spatial scales,in order to build a coherent pic-ture of the processes responsible for species coexistence.Methods We conducted the study in Xishuangbanna Forest Dynamics Plot in Yunnan Province,southwest China.We used four different spatial point process models to estimate the relative importance of disper-sal limitation and environmental filtering.The functional traits and phylogenetic relationships of all individual trees were incorporated in the analyses to generate measures of dissimilarity in terms of pair-wise and nearest-neighbor phylogenetic and functional characteris-tics across life stages and spatial scales.Important Findings We found non-random patterns of phylogenetic and functional turnover across life stages and spatial scales.Environmental filtering structured pairwise phylogenetic and functional beta diversity across spatial scales,while dispersal limitation alone,and in combination with environment filtering,shaped nearest neighbor phylogenetic and functional beta diversity.The relative importance of dispersal limitation and environmental filtering appeared to change with life stage but not with spatial scale.Our findings suggest that phylogenetic and functional beta diversity help to reveal the ecological processes responsible for evolu-tionary and functional assembly and highlight the importance of using a range of different metrics to gain full insights into these processes. | Mengesha Asefa Calum Brown Min Cao Guocheng Zhang Xiuqin Ci Liqing Sha Jie Li Luxiang Lin Jie Yang | 2019 | Journal of Plant Ecology2019，12，2： | 3 |
| 19 | Characteristics of plant calcium fractions for 25 species in Tengger Desert显示文摘Little attention has been paid to plant calcium fractions in the desert.To address the characteristic of the calcium fractions of desert plants,we collected 25 plant species in Tengger Desert,observed the calcium crystals using an optical microscope and determined water soluble calcium,acetic acid soluble calcium,and hydrochloric acid soluble calcium.To do so,we used sequential fractionation procedures to probe the relationships among different functional groups,different growth forms,or different successional stages.The results showed that the psammophyte,the late successional plants,and the drought-resistant shrub and semi-shrub all held considerable calcium oxalate crystal compared to the grassland plants,the early successional plants,and the perennial herb.With the proceeding succession,the acetic acid soluble calcium decreased gradually,and the hydrochloric acid soluble calcium increased gradually.The perennial herb had more water soluble calcium,while shrub held greater hydrochloric acid soluble calcium.The grassland plants held more water soluble calcium,while psammophyte had greater hydrochloric acid soluble calcium.This implies that the plants that are relatively sensitive to drought hold more calcium ion,while the drought-resistance plants hold more calcium oxalate.Thus,the plant calcium components are in close relation to plant drought-resistance,and of important significance in plant physiology of the desert. | HuaCong Ci XingDong lie Rong Li Wei Wu PingPing Xue YuBao Gao HaLin Zhao | 2010 | Research in Cold and Arid Regions2010，2，2： | 3 |
| 20 | Evolutionary transition between invertebrates and vertebrates via methylation reprogramming in embryogenesis显示文摘Major evolutionary transitions are enigmas,and the most notable enigma is between invertebrates and vertebrates,with numerous spectacular innovations.To search for the molecular connections involved,we asked whether global epigenetic changes may offer a clue by surveying the inheritance and reprogramming of parental DNA methylation across metazoans.We focused on gametes and early embryos,where the methylomes are known to evolve divergently between fish and mammals.Here,we find that methylome reprogramming during embryogenesis occurs neither in pre-bilaterians such as cnidarians nor in protostomes such as insects,but clearly presents in deuterostomes such as echinoderms and invertebrate chordates,and then becomes more evident in vertebrates.Functional association analysis suggests that DNA methylation reprogramming is associated with development,reproduction and adaptive immunity for vertebrates,but not for invertebrates.Interestingly,the single HOX cluster of invertebrates maintains unmethylated status in all stages examined.In contrast,the multiple HOX clusters show dramatic dynamics of DNA methylation during vertebrate embryogenesis.Notably,the methylation dynamics of HOX clusters are associated with their spatiotemporal expression in mammals.Our study reveals that DNA methylation reprogramming has evolved dramatically during animal evolution,especially after the evolutionary transitions from invertebrates to vertebrates,and then to mammals. | Xiaocui Xu Guoqiang Li Congru Li Jing Zhang Qiang Wang David KSimmons Xuepeng Chen Naveen Wijesena Wei Zhu Zhanyang Wang Zhenhua Wang Bao Ju Weimin Ci Xuemei Lu Daqi Yu Qian-fei Wang Neelakanteswar Aluru Paola Oliveri Yong EZhang Mark QMartindale Jiang Liu | 2019 | National Science Review2019，6，5： | 2 |
