| 1 | Wheat 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 | 2019 | The Crop Journal2019，7，6： | 8 |
| 2 | Phosphorylation inhibition of protein-tyrosine phosphatase 1B tyrosine-152 induces bone regeneration coupled with angiogenesis for bone tissue engineering显示文摘A close relationship has been reported to exist between cadherin-mediated cell-cell adhesion and integrin-mediated cell mobility,and protein tyrosine phosphatase 1B(PTP1B)may be involved in maintaining this homeostasis.The stable residence of mesenchymal stem cells(MSCs)and endothelial cells(ECs)in their niches is closely related to the regulation of PTP1B.However,the exact role of the departure of MSCs and ECs from their niches during bone regeneration is largely unknown.Here,we show that the phosphorylation state of PTP1B tyrosine-152(Y152)plays a central role in initiating the departure of these cells from their niches and their subsequent recruitment to bone defects.Based on our previous design of a PTP1B Y152 region-mimicking peptide(152RM)that significantly inhibits the phosphorylation of PTP1B Y152,further investigations revealed that 152RM enhanced cell migration partly via integrinαvβ3 and promoted MSCs osteogenic differentiation partly by inhibiting ATF3.Moreover,152RM induced type H vessels formation by activating Notch signaling.Demineralized bone matrix(DBM)scaffolds were fabricated with mesoporous silica nanoparticles(MSNs),and 152RM was then loaded onto them by electrostatic adsorption.The DBM-MSN/152RM scaffolds were demonstrated to induce bone formation and type H vessels expansion in vivo.In conclusion,our data reveal that 152RM contributes to bone formation by coupling osteogenesis with angiogenesis,which may offer a potential therapeutic strategy for bone defects. | Yong Tang Keyu Luo Yin Chen Yueqi Chen Rui Zhou Can Chen Jiulin Tan Moyuan Deng Qijie Dai Xueke Yu Jian Liu Chengmin Zhang Wenjie Wu Jianzhong Xu Shiwu Dong Fei Luo | 2021 | Bioactive Materials2021，6，7： | 3 |

| 4 | Suspended solid abatement in a conical fluidized bed flocculator显示文摘With the random movement of silica gel beads in a conical fluidized bed, micro-vortices resulting from the fluidization promoted the collision and aggregation of suspended fine kaolin powders. The abatement efficiencies of the suspended fine solids under several hydrodynamic conditions were studied, and a suitable control strategy for operating the conical fluidized bed flocculators was identified. The suspended solids abatement efficiency was found to increase with increasing Camp Number and flocculation time (T), but decreased with the increase of velocity gradient (G) within the range studied in this research (165.1-189.6s-1). The abatement efficiencies were all more than 60% at the range of G = 165-180 s 1 and T = 15-33 s at an initial kaolin solid concentration of 150mg·L-1, polymer aluminum chloride dosage of 60 mg· L -1 and sedimentation time of 20 min. However, the formation of flocs was influenced by the liquid back- mixing. Excessive backmixing caused the breakup of ftocs and resulted in difficulty for the fine powders to aggregate and sediment to the reactor bottom. The results of the calculated fractal dimension and measured free sedimenta- tion velocity of flocs obtained at different runs showed similar flocs properties, and indicated an easy control strategy for sedimentation of the flocs. | Dandan ZHOU Shuangshi DONG Keyu LI Huizhong JIANG Dandan SHANG | 2013 | Frontiers of Environmental Science & Engineering2013，7，1： | 1 |
| 5 | Rapid subsurface damage detection of SiC using inductivity coupled plasma显示文摘This paper proposes a method for the rapid detection of subsurface damage(SSD)of Si C using atmospheric inductivity coupled plasma.As a plasma etching method operated at ambient pressure with no bias voltage,this method does not introduce any new SSD to the substrate.Plasma diagnosis and simulation are used to optimize the detection operation.Assisted by an Si C cover,a taper can be etched on the substrate with a high material removal rate.Confocal laser scanning microscopy and scanning electron microscope are used to analyze the etching results,and scanning transmission electron microscope(STEM)is adopted to confirm the accuracy of this method.The STEM result also indicates that etching does not introduce any SSD,and the thoroughly etched surface is a perfectly single crystal.A rapid SSD screening ability is also demonstrated,showing that this method is a promising approach for the rapid detection of SSD. | Yi Zhang Linfeng Zhang Keyu Chen Dianzi Liu Dong Lu Hui Deng | 2021 | International Journal of Extreme Manufacturing2021，3，3： | 1 |

| 8 | Functional 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 | 2022 | Journal of Genetics and Genomics2022，49，8： | 0 |
| 9 | Diagenesis of the Paleogene Sandstones in the DN2 Gas Field,Kuqa Foreland Basin and its Link to Tectonics显示文摘We investigated diagenesis of the sandstones from the DN2 Gas Field of the Kuqa Foreland Basin(KFB),in order to infer the timing of fluid migration and discuss the linkage between fluids and tectonics.The textures and chemical composition of authigenic minerals,fluid evidence from fluid inclusions and formation water measurements were all used to fulfill this aim.Eodiagenesis occurred with the participation of meteoric water and connate water.Mesodiagenesis is related to high salinity fluids,which were attributed as originating from the overlying Neogene Jidike Formation evaporite(principal minerals including halite,anhydrite,glauberite,carnallite and thenardite).The onset of high salinity fluid migration is inferred to occur during the late Miocene(12.4-9.2 Ma)through the use of homogenization temperatures measured in the present study and K-Ar dating of authigenetic illites from previous work.This period is consistent with the crucial phase(13-10 Ma)that witnessed the rapid uplift of the southern Tianshan Mts and the stage when calcite and anhydrite veins formed in the studied strata.We thus argue that diagenesis related to high salinity fluids occurred as a response to the Tianshan Mts'rapid uplift and related tectonic processes.The flow of high salinity fluids was probably driven by a density gradient and channeled and focused by fractures formed contemporaneously. | YU Guoding YUAN Jing LIU Keyu YANG Xianzhang DONG Daotao MA Pengjie HUANG Chiqiang | 2023 | Acta Geologica Sinica(English Edition)2023，97，5： | 0 |
| 10 | Growing curly graphene layer boosts hard carbon with superior sodium-ion storage显示文摘Benefiting from the distinctive ordering degree and local microstructure characteristics,hard carbon(HC)is considered as the most promising anode for sodium-ion batteries(SIBs).Unfortunately,the low initial Coulombic efficiency(ICE)and limited reversible capacity severely impede its extensive application.Here,a homogeneous curly graphene(CG)layer with a micropore structure on HC is designed and executed by a simple chemical vapor deposition method(without catalysts).CG not only improves the electronic/ionic conductivity of the hard carbon but also effectively shields its surface defects,enhancing its ICE.In particular,due to the spontaneous curling structural characteristics of CG sheets(CGs),the micropores(≤2 nm)formed provide additional active sites,increasing its capacity.When used as a sodium-ion battery anode,the HC-CG composite anode displayed an outstanding reversible capacity of 358 mAh·g^(-1),superior ICE of 88.6%,remarkable rate performance of 145.8 mAh·g^(-1)at 5 A·g^(-1),and long cycling life after 1000 cycles with 88.6%at 1 A·g^(-1).This work provides a simple defect/microstructure turning strategy for hard carbon anodes and deepens the understanding of Na+storage behavior in the plateau region,especially on the pore-filling mechanism by forming quasi-metallic clusters. | Minghao Song Qiang Song Tao Zhang Xiaomei Huo Zezhou Lin Zhaowen Hu Lei Dong Ting Jin Chao Shen Keyu Xie | 2023 | Nano Research2023，16，7： | 0 |
