1Wheat powdery mildew resistance gene Pm64 derived from wild emmer (Triticum turgidum var.dicoccoides) is tightly linked in repulsion with stripe rust resistance gene Yr5显示文摘Stripe rust and powdery mildew are both devastating diseases for durum and common wheat.Pyramiding of genes conferring resistance to one or more diseases in a single cultivar is an important breeding approach to provide broader spectra of resistances in wheat improvement. A new powdery mildew resistance gene originating from wild emmer(Triticum turgidum var.dicoccoides) backcrossed into common wheat(T. aestivum) line WE35 was identified. It conferred an intermediate level of resistance to Blumeria graminis f. sp. tritici isolate E09 at the seedling stage and a high level of resistance at the adult plant stage. Genetic analysis showed that the powdery mildew resistance in WE35 was controlled by a dominant gene designated Pm64. Bulked segregant analysis(BSA) and molecular mapping indicated that Pm64 was located in chromosome bin 2 BL4-0.50–0.89. Polymorphic markers were developed from the corresponding genomic regions of Chinese Spring wheat and wild emmer accession Zavitan to delimit Pm64 to a 0.55 cM genetic interval between markers WGGBH1364 and WGGBH612, corresponding to a 15 Mb genomic region on Chinese Spring and Zavitan 2 BL, respectively. The genetic linkage map of Pm64 is critical for fine mapping and cloning. Pm64 was completely linked in repulsion with stripe rust resistance gene Yr5. Analysis of a larger segregating population might identify a recombinant line with both genes as a valuable resource in breeding for resistance to powdery mildew and stripe rust.Deyun Zhang Keyu Zhu Lingli Dong Yong Liang Genqiao Li Tilin Fang Guanghao Guo Qiuhong Wu Jingzhong Xie Yongxing Chen Ping Lu Miaomiao Li Huaizhi Zhang Zhenzhong Wang Yan Zhang Qixin Sun Zhiyong Liu 2019The Crop Journal2019,7,6:8

5A multiphase sodium vanadium phosphate cathode material for high-rate sodium-ion batteries显示文摘The unsatisfactory rate capability and poor cycling stability at high rate of sodium-ion batteries(SIBs) have impeded their practical applications. Herein, a Na_(3)V_(2)(PO_(4))_(3)/Na_(3)V_(3)(PO_(4))_(4) multiphase cathode materials for high-rate and long cycling SIBs was successfully synthesized by regulation the stoichiometric ratio of raw materials. The combined experiment and simulation results show that the multiphase materials consisted of NASICON structural phase Na3V2(PO4)3 and layered structure phase Na_(3)V_(3)(PO_(4))_(4), possess abundant phase boundaries. Electrochemical experiments demonstrate that the multiphase materials maintain a remarkable reversible capacity of 69.0 mA h g^(-1) even at an ultrahigh current density of 100 C with a high capacity retention of 81.25 % even after 10,000 cycles. Na_(3)V_(2)(PO_(4))_(3)/Na_(3)V_(3)(PO_(4))_(4) electrode exhibits a higher working voltage, superior rate capability and better cycling stability than Na_(3)V_(2)(PO_(4))_(3) electrode, which indicates that the introduction of second phase can be an effective strategy for the development of novel cathode materials for SIBs.Chuan Wang Hai Long Lijiao Zhou Chao Shen Wei Tang Xiaodong Wang Bingbing Tian Le Shao Zhanyuan Tian Haijun Su Keyu Xie 2021Journal of Materials Science & Technology2021,,7:1

8Chemically stable polypyrrole-modified liquid metal nanoparticles with the promising photothermal conversion capability显示文摘The gallium-based eutectic alloy has gained particular attention in various fields due to its natural features of metallic fluids at room temperature.However,these alloy nanoparticles are extremely susceptible to be oxidized accompanied by de-alloying during the preparation,storage,and application.Here,with the assistance of the macromolecular stabilizer and dopant,sodium dodecylbenzene sulfonate(SDBS),we demonstrate a stable polypyrrole(PPy)layer acts as a protected“armor”on the surface of liquid metal(i.e.,gallium-tin,EGaSn).SDBS enables the EGa Sn to keep well dispersion and protects dispersed EGaSn from being durative oxidized before PPy coating.Furthermore,PPy greatly inhibits the oxidation of EGaSn owing to the strong interface interaction between the lone pair electrons around the N atoms of Py rings and the Ga3+orbit of EGaSn.Consequently,the fabricated EGaSn nanoparticles possess the features of smaller particle size,superior uniform distribution,and stronger antioxidant capacity.The prepared EGaSn@PPy composite exhibits superior stability even after storing in an aqueous solution for up to 100 days.As a proof-of-concept application,the EGaSn@PPy composite displays remarkable photothermal performance with an enhanced photothermal conversion efficiency.This work provides a novel surface engineering strategy to ameliorate liquid metal for photothermal therapy applications.Yaqin Qi Ting Jin Kai Yuan Jingyuan You Chao Shen Keyu Xie 2022Journal of Materials Science & Technology2022,,32:1
9A multifunctional electrolyte with highly-coordinated solvation structure-in-nonsolvent for rechargeable lithium batteries显示文摘Rechargeable lithium-based battery is hailed as next-generation high-energy-density battery systems.However, growth of lithium dendrites, shuttle effect of lithium polysulfides intermediates and unstable interphase of high-voltage intercalation-type cathodes largely prevent their practical deployment.Herein, to fully conquer the three challenges via one strategy, a novel electrolyte with highlycoordinated solvation structure-in-nonsolvent is designed. On account of the particular electrolyte structure, the shuttle effect is completely suppressed by quasi-solid conversion of S species in Li-S batteries,with a stable cycle performance even at lean electrolyte(5μL mg^(-1)). Simultaneously, in-situ-formed highly-fluorinated interphases can not only lower Li+diffusion barrier to ensure uniform nucleation of Li but also improve stability of NCM cathodes, which enable excellent capacity retention of Lik LiNi(0.5)Co(0.2)Mn(0.3)O2 batteries under conditions toward practical applications(high loading of 2.7 m Ah cm^(-2) and lean electrolyte of 5 m L Ah^(-1)). Besides, the electrolyte is also nonflammable. This electrolyte structure offers useful guidelines for the design of novel organic electrolytes for practical lithium-based batteries.Hui Zhao Jjinlei Gu Yuliang Gao Qian Hou Zengying Ren Yaqin Qi Kun Zhang Chao Shen Jun Zhang Keyu Xie 2020Journal of Energy Chemistry2020,29,12:1

13Uniform-dispersed ZnS quantum dots loading on graphene as a promising anode for potassium-ion batteries显示文摘The potassium-ion batteries(PIBs)have become the promising energy storage devices due to their relatively moderate cost and plenteous potassium resources.Whereas,the main drawback of PIBs is unsatisfacto ry electrochemical perfo rmance induced by the larger ionic radius of potassium ion.Herein,we report a well-designed,uniform-dispersed,and morphology-controllable zinc sulfide(ZnS)quantum dots loading on graphene as an anode in the PIBs.The directed uniform dispersion of the in-situ growing ZnS quantum dots(~2.8 nm in size)on graphene can mitigate the volume effect during the insertionextraction process and shorten the migration path of potassium ions.As a result,the battery exhibits superior cycling stability(350.4 mAh/g over 200 cycles at 0.1 A/g)and rate performance(98.8 mAh/g at2.0 A/g).We believe the design of active material with quantum dot-minimized size provides a novel route into PIBs and contributes to eliminating the major electrode failure issues of the system.Yaqin Qi Yong Yang Qian Hou Kun Zhang Hui Zhao Haijun Su Lijiao Zhou Xingrui Liu Chao Shen Keyu Xie 2021Chinese Chemical Letters2021,32,3:1
14Superior lithium storage performance in MoO_(3) by synergistic effects:Oxygen vacancies and nanostructures显示文摘Molybdenum trioxide(MoO_(3))has recently attracted wide attention as a typical conversion-type anode of Li-ion batteries(LIBs).Nevertheless,the inferior intrinsic conductivity and rapid capacity fading during charge/discharge process seriously limit large-scale commercial application of MoO_(3).Herein,the density function theory(DFT)calculations show that electron-proton co-doping preferentially bonds symmetric oxygen to form unstable HxMoO_(3).When the-OH-group in HxMoO_(3) is released into the solution in the form of H_(2)O,it is going to form MoO_(3-x)with lower binding energy.By the means of both electron-proton co-doping and high-energy nanosizing,oxygen vacancies and nanoflower structure are introduced into MoO_(3) to accelerate the ion and electronic diffusion/transport kinetics.Benefitting from the promotion of ion diffusion kinetics related to nanostructures,as well as both the augmentation of active sites and the improvement of electrical conductivity induced by oxygen vacancies,the MoO_(3-x)/nanoflower structures show excellent lithium-ion storage performance.The prepared specimen has a high lithium-ion storage capacity of 1261 mA h g^(-1)at 0.1 A g^(-1)and cyclic stability(450 cycle),remarkably higher than those of previously reported MoO_(3)-based anode materials.Xueyang Hou Miao Ruan Lijiao Zhou Jianchun Wu Bicheng Meng Wenlong Huang Kenan Zhong Kai Yang Zhao Fang Keyu Xie 2023Journal of Energy Chemistry2023,,3:0
15A telomere-to-telomere reference genome provides genetic insight into the pentacyclic triterpenoid biosynthesis in Chaenomeles speciosa显示文摘Chaenomeles speciosa(2n=34),a medicinal and edible plant in the Rosaceae,is commonly used in traditional Chinese medicine.To date,the lack of genomic sequence and genetic studies has impeded efforts to improve its medicinal value.Herein,we report the use of an integrative approach involving PacBio HiFi(third-generation)sequencing and Hi-C scaffolding to assemble a high-quality telomere-to-telomere genome of C.speciosa.The genome comprised 650.4 Mb with a contig N50 of 35.5 Mb.Of these,632.3 Mb were anchored to 17 pseudo-chromosomes,in which 12,4,and 1 pseudo-chromosomes were represented by a single contig,two contigs,and four contigs,respectively.Eleven pseudo-chromosomes had telomere repeats at both ends,and four had telomere repeats at a single end.Repetitive sequences accounted for 49.5%of the genome,while a total of 45515 protein-coding genes have been annotated.The genome size of C.speciosa was relatively similar to that of Malus domestica.Expanded or contracted gene families were identified and investigated for their association with different plant metabolisms or biological processes.In particular,functional annotation characterized gene families that were associated with the biosynthetic pathway of oleanolic and ursolic acids,two abundant pentacyclic triterpenoids in the fruits of C.speciosa.Taken together,this telomere-to-telomere and chromosome-level genome of C.speciosa not only provides a valuable resource to enhance understanding of the biosynthesis of medicinal compounds in tissues,but also promotes understanding of the evolution of the Rosaceae.Shaofang He Duanyang Weng Yipeng Zhang Qiusheng Kong Keyue Wang Naliang Jing Fengfeng Li Yuebin Ge Hui Xiong Lei Wu De-Yu Xie Shengqiu Feng Xiaqing Yu Xuekui Wang Shaohua Shu Zhinan Mei 2023Horticulture Research2023,10,10:0
16Regulating electrodeposition behavior through enhanced mass transfer for stable lithium metal anodes显示文摘Electrode process kinetics is a key part that determines the morphology of metal electrodeposition.However,the liquid-phase mass transfer process and its effect on lithium(Li)metal electrodeposition are still poorly understood.Herein,the effect of mass transfer on the electrodeposition behavior of Li metal is explored.Experiments and COMSOL Multiphysics simulations reveal that the enhanced mass transfer,which is induced by ultrasonic wave,can homogenize the ion flow on the surface of electrode to obtain uniform Li nucleation.Meanwhile,the rapid mass transfer of Li^(+)provides sufficient cations around the germinated Li to avoid preferential growth of Li in a specific direction.Based on the simultaneous regulation of nucleation and growth behavior,a smooth and compact Li deposits can be achieved,which exhibit a small polarization voltage during repeated Li plating/striping and a considerably enhanced cyclability.This work enriches the fundamental understanding of Li electrodeposition without dendrite structure and affords fresh guidance to develop dendrite-free metal anodes for metal-based batteries.Yuliang Gao Fahong Qiao Jingyuan You Chao Shen Hui Zhao Jinlei Gu Zengying Ren Keyu Xie Bingqing Wei 2021Journal of Energy Chemistry2021,30,4:0
17Radiation effects on lithium metal batteries显示文摘The radiation tolerance of energy storage batteries is a crucial index for universe exploration or nuclear rescue work,but there is no thorough investigation of Li metal batteries.Here,we systematically explore the energy storage behavior of Li metal batteries under gamma rays.Degradation of the performance of Li metal batteries under gamma radiation is linked to the active materials of the cathode,electrolyte,binder,and electrode interface.Specifically,gamma radiation triggers cation mixing in the cathode active material,which results in poor polarization and capacity.Yuliang Gao Fahong Qiao Weiping Hou Li Ma Nan Li Chao Shen Ting Jin Keyu Xie 2023The Innovation2023,4,4:0
18The Efficacy of a Live Attenuated TW I-Type Infectious Bronchitis Virus Vaccine Candidate显示文摘Infectious bronchitis(IB) is a highly contagious avian disease caused by infection with infectious bronchitis virus(IBV),which seriously affects the development of the global poultry industry. The distribution of TW I-type IBV in China has increased in recent years, becoming a widespread genotype. We previously isolated a TW I-type IBV strain termed CK/CH/GD/GZ14 in 2014, but its pathogenicity and possibility for vaccine development were not explored. Therefore, this research aimed to develop a live-attenuated virus vaccine based on the CK/CH/GD/GZ14 strain. The wild type IBV CK/CH/GD/GZ14 strain was serially passaged in SPF embryos for 145 generations. The morbidity and mortality rate of wildtype strain in 14 day-old chickens is 100% and 80% respectively, while the morbidity rate in the attenuated strain was 20%in the 95 th and 105 th generations and there was no death. Histopathological observations showed that the pathogenicity of the 95th and 105th generations in chickens was significantly weakened. Further challenge experiments confirmed that the attenuated CK/CH/GD/GZ14 strain in the 95th and 105 th generations could resist CK/CH/GD/GZ14(5th generation)infection and the protection rate was 80%. Tracheal cilia stagnation, virus shedding, and viral load experiments confirmed that the 95 th and 105th generations provide good immune protection in chickens, and the immunogenicity of the 105th generation is better than that of the 95th generation. These data suggest that the attenuated CK/CH/GD/GZ14 strain in the105th generation may be applied as a vaccine candidate against TW I-type IBV.Xinheng Zhang Tong Chen Sheng Chen Yu Nie Zi Xie Keyu Feng Huanmin Zhang Qingmei Xie 2021Virologica Sinica2021,36,6:0
19Functional characterization of powdery mildew resistance gene MIIW172,a new Pm60 allele and its allelic variation in wild emmer wheat显示文摘Wild emmer wheat(Triticum dicoccoides,WEW)is an immediate progenitor of both the cultivated tetraploid and hexaploid wheats and it harbors rich genetic diversity against powdery mildew caused by Blumeria graminis f.sp.tritici(Bgt).A powdery mildew resistance gene Ml I^(W172)originated from WEW accession I^(W172)(G-797-M)is fine mapped in a 0.048 centimorgan(c M)genetic interval on 7 AL,corresponding to a genomic region spanning 233 kb,1 Mb and 800 kb in Chinese Spring,WEW Zavitan,and T.urartu G1812,respectively.Ml I^(W172)encodes a typical NLR protein NLRI^(W172)and physically locates in an NBS-LRR gene cluster.NLRI^(W172)is subsequently identified as a new allele of Pm60,and its function is validated by EMS mutagenesis and transgenic complementation.Haplotype analysis of the Pm60 alleles reveals diversifications in sequence variation in the locus and presence and absence variations(PAV)in WEW populations.Four common single nucleotide variations(SNV)are detected between the Pm60 alleles from WEW and T.urartu,indicative of speciation divergence between the two different wheat progenitors.The newly identified Pm60 alleles and haplotypes in WEW are anticipated to be valuable for breeding powdery mildew resistance wheat cultivars via marker-assisted selection.Qiuhong Wu Yongxing Chen Beibei Li Jing Li Panpan Zhang Jingzhong Xie Huaizhi Zhang Guanghao Guo Ping Lu Miaomiao Li Keyu Zhu Wenling Li Tzion Fahima Eviatar Nevo Hongjie Li Lingli Dong Zhiyong Liu 2022Journal of Genetics and Genomics2022,49,8:0
20Understanding the Coffee ring Effect on Self-discharge Behavior of Printed micro-Supercapacitors显示文摘Printed micro-supercapacitor exhibits its flexibility in geometry design and integration,showing unprecedented potential in powering the internet of things and portable devices.However,the printing process brings undesired processing defects(e.g.,coffee ring effect),resulting in severe self-discharge of the printed micro-supercapacitors.The impact of such problems on device performance is poorly understood,limiting further development of microsupercapacitors.Herein,by analyzing the self-discharge behavior of fully printed micro-supercapacitors,the severe self-discharge problem is accelerated by the ohmic leakage caused by the coffee ring effect on an ultrathin polymer electrolyte.Based on this understanding,the coffee ring effect was successfully eradicated by introducing graphene oxide in the polymer electrolyte,achieving a decline of 99%in the self-discharge rate.Moreover,the micro-supercapacitors with uniformly printed polymer electrolyte present 7.64 F cm^(-3)volumetric capacitance(14.37 mF cm^(-2)areal capacitance),exhibiting about 50%increase compared to the one without graphene oxide addition.This work provides a new insight to understand the relationship between processing defects and device performance,which will help improve the performance and promote the application of printed micro-supercapacitors.Jingzhi Hu Zhaohua Xu Kai Yuan Chao Shen Keyu Xie Bingqing Wei 2022Energy & Environmental Materials2022,5,1:0
