1Changes in global potential vegetation distributions from 1911 to 2000 as simulated by the Comprehensive Sequential Classification System approach显示文摘Vegetation classification models play an important role in studying the response of the terrestrial ecosystem to global climate change. In this paper, we study changes in global Potential Natural Vegetation (PNV) distributions using the Comprehensive Sequential Classification System (CSCS) approach, a technique that combines geographic information systems. Results indicate that on a global scale there are good agreements among maps produced by the CSCS method and the globally well-accepted Holdridge Life Zone (HLZ) and BIOME4 PNV models. The potential vegetation simulated by the CSCS approach has 6 major latitudinal zones in the northern hemisphere and 2 in the southern hemisphere. In mountainous areas it has obvious altitudinal distribution characteristics due to topographic effects. The distribution extent for different PNV classes at various periods has different characteristics. It had a decreasing trend for the tundra and alpine steppe, desert, sub-tropical forest and tropical forest categories, and an increasing trend for the temperate forest and grassland vegetation categories. The simulation of global CSCS-based PNV classes helps to understand climate-vegetation relationships and reveals the dynamics of potential vegetation distributions induced by global changes. Compared with existing statistical and equilibrium models, the CSCS approach provides similar mapping results for global PNV and has the advantage of improved simulation of grassland classes.LIANG TianGang FENG QiSheng CAO JianJun XIE HongJie LIN HuiLong ZHAO Jun REN JiZhou 2012Chinese Science Bulletin2012,57,11:23

5Synthesis,structure and optical properties of novel thermally robust Dy^(3+)-doped Ca_(9)Sc(PO_(4))_(7) phosphors for NUV-excited white LEDs显示文摘The powder samples of Ca_(9)Sc(PO_(4))_(7):xDy^(^(3+))white emitting phosphors were prepared via a solid state reaction technique.The Ca_(9)Sc(PO_(4))_(7):Dy^(3+)samples were researched by using the GSAS Rietveld refinement and X-ray diffraction(XRD) methods,and SEM images and elemental maps were recorded.Under 350 nm excitatio n,the emission spectra of Ca_(9)Sc(PO_(4))_(7):xDy^(3+)samples have two obvious peaks and one weak peak at 484,572 and660 nm,corresponding to the characteristic electron transitions of(^(4)F_(9/2)→ ^(6)H_(15/2),blue),(^(4)F_(9/2)→ ^(6)H_(13/2),yellow) and(^(4)F_(9/2)→ 6 H11/2,red),respectively.The concentration quenching effect,decay lifetime and thermal quenching of the as-synthesized Ca_(9)Sc(PO_(4))_(7):Dy^(3+)samples were researched systematically.The Ca_(9)Sc(PO_(4))_(7):0.02 Dy^(3+)phosphor possesses a good thermal stability,of which the emission intensity at 423 K can maintain 79% of the initial value(273 K).In addition,through the study of the chro maticity coordinates of the Ca_(9)Sc(PO_(4))_(7):0.02 Dy^(3+)phosphor,it is found that it is located in the white region,and the Commission Internationalede L’Eclairage(CIE) chromaticity coordinates are(0.339,0.389),The above results show that Ca_(9)Sc(PO_(4))_(7):xDy^(3+)phosphors can be excellent candidate material for applications in NUV-excited white LEDs.Haiyan Wu Huimin Li Lihong Jiang Ran Pang Su Zhang Da Li Guanyu Liu Chengyu Li Jing Feng Hongjie Zhang 2021Journal of Rare Earths2021,39,3:4
6Microwave-assisted synthesis of nanoscale Eu(BTC)(H_2O)·DMF with tunable luminescence显示文摘Nanoscale europium(III) metal-organic frameworks, Eu(BTC)(H2O)?DMF, were synthesized by rapid microwave-assisted method. The components of the as-prepared products were confirmed by the elemental analysis, X-ray powder diffraction(XRD), thermal gravimetric analysis(TGA) and Fourier-transform infrared spectra(FTIR) analyses. Eu(BTC)(H2O)?DMF with various morphologies, including particle-like, rod-like, straw-sheaf-like nanostructures, could be simply prepared by controlling the concentrations of the starting reactants. The optical measurements on the obtained Eu(BTC)(H2O)?DMF indicated that all the nanomaterials show the characteristic emissions of the Eu3+ ions at 578, 590, 612, 650, and 699 nm, which were attributed to 5D0?7FJ(J=0–4) transitions of the Eu3+ ion, respectively. It was also noticed that the luminescent properties of the as-prepared products were heavily dependent on the morphologies and sizes of the nanomaterials. The assembled straw-sheaf-like architectures displayed the strongest emissions and the longest luminescence lifetime, which was mainly due to the fewest surface defects.Song Dang Shuyan Song Jing Feng Hongjie Zhang 2015Science China Chemistry2015,58,6:3

8Succinate dehydrogenase SDH1–1 positively regulates cotton resistance to Verticillium dahliae through a salicylic acid pathway显示文摘Background:Verticillium wilt,caused by the soil-borne fungus of Verticillium dahliae Kleb.,is one of the most devastating diseases of cotton.The complex mechanism underlying cotton resistance to Verticillium wilt remains uncharacterized.Identifying an endogenous resistance gene may be helpful to control this disease.Previous studies revealed that succinate dehydrogenase(SDH)is involved in reactive oxygen species(ROS)-induced stress signaling pathway that is likely to be triggered by salicylic acid(SA).Here,through the metabolomics and differential expression analyses in wilt-inoculated cotton(Gossypium hirsutum),we noticed that Gh SDH1–1 gene in cotton may play an important role in the resistance to V.dahlia.Then we reported Gh SDH1–1 gene and its functional analysis in relation to the resistance of cotton to V.dahliae.Results:The Gh SDH1–1 gene in cotton root was significantly up-regulated after V.dahlia inoculation,and its expression level peaked at 12 and 24 h post-infection.SA can also induce the up-regulation of Gh SDH1–1.Additionally,the functional analysis showed that Gh SDH1–1-silenced cotton was more susceptible to V.dahliae than the control because of the significant decrease in abundance of immune-related molecules and severe damage to the SA-signaling pathway.In Arabidopsis thaliana,high expression of Gh SDH1–1 conferred high resistance to V.dahliae.Arabidopsis that overexpressed Gh SDH1–1 had higher resistance to V.dahliae infection compared with the wild-type.Conclusions:Our findings provide new insights into the role of Gh SDH1–1;it positively regulates cotton resistance to Verticillium wilt.The regulatory mechanism of Gh SDH1–1 is closely related to SA-related signaling pathway.ZHANG Xiangyue FENG Zili ZHAO Lihong LIU Shichao WEI Feng SHI Yongqiang FENG Hongjie ZHU Heqin 2020Journal of Cotton Research2020,3,2:3

12A review of the pathogenicity mechanism of Verticillium dahliae in cotton显示文摘Verticillium wilt,caused by the notorious fungal pathogen Verticillium dahliae,is one of the main limiting factors for cotton production.Due to the stable dormant structure microsclerotia,long-term variability and co-evolution with host plant,its pathogenicity mechanism is very complicated,and the interaction mechanism between pathogen and host plant is also unclear.So identification and functional analysis of the genes involved in the pathogenicity or virulence of this fungus will benefit to uncover the molecular pathogenic mechanism of V.dahliae.In this review,many multifunction genes covering microsclerotia development,pathogen infection,effector proteins,transcription factors,horizontal gene transfer and trans-kingdom RNA silencing have been summarized to provide a theoretical basis to deep understand the molecular pathogenicity mechanism of V.dahliae and promote to effectively control Verticillium wilt.Furtherly,these pathogenicity-related genes may be considered as targets for effective control of Verticillium wilt in cotton.ZHANG Yalin ZHOU Jinglong ZHAO Lihong FENG Zili WEI Feng BAI Hongyan FENG Hongjie ZHU Heqin 2022Journal of Cotton Research2022,5,1:2
13Proteinaceous Fibers with Outstanding Mechanical Properties Manipulated by Supramolecular Interactions显示文摘Proteinaceous fibers based on spidroins have attracted widespread attention due to their lightweight and mechanically strong properties.Presently,mechanical modulation is mainly dependent on the ultrahigh molecular weight of recombinant proteins.This makes it difficult to construct and express the target proteins.It is thus significant to develop alternative strategies for the fabrication of robust biological fibers.Herein,we demonstrate one new type of engineered protein fibers using electrostatic complexation of the cationic elastins and anionic dihydroxyphenylalanine surfactants.Interestingly,the mechanical performance of the resulting fibers can be modulated by multiple supramolecular interactions in the system including electrostatic force,hydrogen bonding,metal coordination,cation-πand other aromatic interactions.Consequently,significant alternation of the fibers’breaking strength(from 32 to 160 MPa),Young’s modulus(from 0.8 to 17 GPa),and toughness(from 1.2 to 99 MJ·m-3)has been achieved.Moreover,the fibers exhibit high plasticity;for example,the formation of different helical structures,and strong fluorescence after the introduction of Tb chelation.Therefore,this study offers new strategies for the mechanical regulation of engineered protein fibers.Jing Sun Bo Li Fan Wang Jing Feng Chao Ma Kai Liu Hongjie Zhang 2021CCS Chemistry2021,3,6:2

19Efficacy evaluation and mechanism of Bacillus subtilis EBS03 against cotton Verticillium wilt显示文摘Background:In our previous study,a strain EBS03 with good biocontrol potential was screened out of 48 strains of cotton endophyte Bacillus subtilis by evaluating the controlling effect against cotton Verticillium wilt.However,its mechanism for controlling Verticillium wilt remains unclear.The objective of this study was to further clarify its con-trolling effect and mechanism against cotton Verticillium wilt.Results:The results of confrontation culture test and double buckle culture test showed that the inhibitory effects of EBS03 volatile and nonvolatile metabolite on mycelium growth of Verticillium dahliae were 70.03%and 59.00%,respectively;the inhibitory effects of sporulation and microsclerotia germination were 47.16%and 70.06%,respec-tively.In the greenhouse test,the EBS03 fermentation broth root irrigation had the highest controlling effect at 87.11%on cotton Verticillium wilt,and significantly promoted the growth of cotton seedlings.In the field experi-ment,the controlling effect of EBS03 fermentation broth to cotton Verticillium wilt was 42.54%at 60 days after cotton sowing,and the boll number per plant and boll weight in EBS03 fermentation broth seed soaking,root irrigation,and spraying treatments significantly increased by 19.48%and 7.42%,30.90%and 2.62%,15.99%and 9.20%,respec-tively.Furthermore,EBS03 improved the resistance of cotton leaves against the infection of V.dahliae,and induced the outbreak of reactive oxygen species and accumulation of callose.In addition,the results of real time fluorescent quantitative polymerase chain reaction(RT-qPCR)detection showed that EBS03 significantly induced upregulation expression level of defense-related genes PAL,POD,PPO,and PR10 in cotton leaves,enhanced cotton plant resistance to V.dahliae,and inhibited colonization level of this fungal pathogen in cotton.Conclusion:Bacillus subtilis EBS03 has a good biological defense capability,which can inhibit the growth and coloni-zation level of V.dahliae,and activate the resistance of cotton to Verticillium wilt,thus increase cotton yield.BAI Hongyan FENG Zili ZHAO Lihong FENG Hongjie WEI Feng ZHOU Jinglong GU Aixing ZHU Heqin PENG Jun ZHANG Yalin 2022Journal of Cotton Research2022,5,4:1
20Engineering CeO_(2)/CuO heterostructure anchored on upconversion nanoparticles with boosting ROS generation-primed apoptosisferroptosis for cancer dynamic therapy显示文摘Highly toxic reactive oxygen species(ROS)induced apoptosis and ferroptosis have been considered as significant cell death pathways for cancer therapy.However,insufficient amount of intracellular ROS extremely restricts the therapeutic effect.Toward this,we report a rationally designed nanocomposite(mUCC)with enhanced ROS generation ability,inducing the combination of apoptosis and ferroptosis through synergistic photodynamic therapy(PDT)and chemodynamic therapy(CDT).Under 808 nm near-infrared(NIR)light irradiation,photocatalytic reaction is triggered starting from the separation of electron-hole pairs on the surface of heterojunction(CeO_(2)/CuO),realizing improved ROS production.Simultaneously,mUCC served as Fenton-like agent exhibits considerable ability to generate highly toxic·OH under tumor microenvironment(TME).The boosted accumulation of ROS disrupts the redox balance within tumor cells and results in the integration of apoptosis and ferroptosis.In addition,mUCC shows satisfactory tumor targeting property benefiting from the cancer cell membrane functionalization under the guidance of magnetic resonance imaging(MRI)and NIR fluorescence imaging.The intelligent mUCC with good biocompatibility and excellent antitumor response achieves efficient tumor elimination under synergistic PDT and CDT.This work offers an elective approach for further development of ROS-based therapeutic nanoplatform in cancer therapy.Xuan Gao Jing Feng Kehong Lv Yifei Zhou Ruohao Zhang Shuyan Song Hongjie Zhang Daguang Wang 2023Nano Research2023,16,4:1
