| 1 | Transcription factor WRKY22 regulates canker susceptibility in sweet orange (Citrus sinensis Osbeck) by enhancing cell enlargement and CsLOB1 expression显示文摘Pathological hypertrophy(cell enlargement)plays an important role in the development of citrus canker,but its regulators are largely unknown.Although WRKY22 is known to be involved in pathogen-triggered immunity and positively regulates resistance to bacterial pathogens in Arabidopsis,rice and pepper,the CRISPR/Cas9-mediated partial knockout of CsWRKY22 improves resistance to Xanthomonas citri subsp.citri(Xcc)in Wanjincheng orange(Citrus sinensis Osbeck).Here,we demonstrate that CsWRKY22 is a nucleus-localized transcriptional activator.CsWRKY22-overexpressing plants exhibited dwarf phenotypes that had wrinkled and thickened leaves and were more sensitive to Xcc,whereas CsWRKY22-silenced plants showed no visible phenotype changes and were more resistant to Xcc.Microscopic observations revealed that the overexpression of CsWRKY22 increased cell size in the spongy mesophyll.Transcriptome analysis showed that cell growth-related pathways,such as the auxin and brassinosteroid hormonal signaling and cell wall organization and biogenesis pathways,were significantly upregulated upon CsWRKY22 overexpression.Interestingly,CsWRKY22 activated the expression of CsLOB1,which is a key gene regulating susceptibility to citrus canker.We further confirmed that CsWRKY22 bound directly to the W-boxes just upstream of the transcription start site of CsLOB1 in vivo and in vitro.We conclude that CsWRKY22 enhances susceptibility to citrus canker by promoting host hypertrophy and CsLOB1 expression.Thus,our study provides new insights into the mechanism regulating pathological hypertrophy and the function of WRKY22 in citrus. | Qin Long Meixia Du Junhong Long Yu Xie Jingyun Zhang Lanzhen Xu Yongrui He Qiang Li Shanchun Chen Xiuping Zou | 2021 | Horticulture Research2021，8，1： | 5 |
| 2 | Hollow Gradient-Structured Iron-Anchored Carbon Nanospheres for Enhanced Electromagnetic Wave Absorption显示文摘In the present paper,a microwave absorber with nanoscale gradient structure was proposed for enhancing the electromagnetic absorption performance.The inorganic-organic competitive coating strategy was employed,which can effectively adjust the thermodynamic and kinetic reactions of iron ions during the solvothermal process.As a result,Fe nanoparticles can be gradually decreased from the inner side to the surface across the hollow carbon shell.The results reveal that it offers an outstanding reflection loss value in combination with broadband wave absorption and flexible adjustment ability,which is superior to other relative graded distribution structures and satisfied with the requirements of lightweight equipment.In addition,this work elucidates the intrinsic microwave regulation mechanism of the multiscale hybrid electromagnetic wave absorber.The excellent impedance matching and moderate dielectric parameters are exhibited to be the dominative factors for the promotion of microwave absorption performance of the optimized materials.This strategy to prepare gradient-distributed microwave absorbing materials initiates a new way for designing and fabricating wave absorber with excellent impedance matching property in practical applications. | Cao Wu Jing Wang Xiaohang Zhang Lixing Kang Xun Cao Yongyi Zhang Yutao Niu Yingying Yu Huili Fu Zongjie Shen Kunjie Wu Zhenzhong Yong Jingyun Zou Bin Wang Zhou Chen Zhengpeng Yang Qingwen Li | 2023 | Nano-Micro Letters2023，15，1： | 2 |
| 3 | Histones released by NETosis enhance the infectivity of SARS-CoV-2 by bridging the spike protein subunit 2 and sialic acid on host cells显示文摘Neutrophil extracellular traps(NETs)can capture and kill viruses,such as influenza viruses,human immunodeficiency virus(HIV),and respiratory syncytial virus(RSV),thus contributing to host defense.Contrary to our expectation,we show here that the histones released by NETosis enhance the infectivity of SARS-CoV-2,as found by using live SARS-CoV-2 and two pseudovirus systems as well as a mouse model.The histone H3 or H4 selectively binds to subunit 2 of the spike(S)protein,as shown by a biochemical binding assay,surface plasmon resonance and binding energy calculation as well as the construction of a mutant S protein by replacing four acidic amino acids.Sialic acid on the host cell surface is the key molecule to which histones bridge subunit 2 of the S protein.Moreover,histones enhance cell-cell fusion.Finally,treatment with an inhibitor of NETosis,histone H3 or H4,or sialic acid notably affected the levels of sgRNA copies and the number of apoptotic cells in a mouse model.These findings suggest that SARS-CoV-2 could hijack histones from neutrophil NETosis to promote its host cell attachment and entry process and may be important in exploring pathogenesis and possible strategies to develop new effective therapies for COVID-19. | Weiqi Hong Jingyun Yang Jun Zou Zhenfei Bi Cai He Hong Lei Xuemei He Xue Li Aqu Alu Wenyan Ren Zeng Wang Xiaohua Jiang Kunhong Zhong Guowen Jia Yun Yang Wenhai Yu Qing Huang Mengli Yang Yanan Zhou Yuan Zhao Dexuan Kuang Junbin Wang Haixuan Wang Siyuan Chen Min Luo Ziqi Zhang Tiangi Lu Li Chen Haiying Que Zhiyao He Qiu Sun Wei Wang Guobo Shen Guangwen Lu Zhiwei Zhao Li Yang Jinliang Yang Zhenling Wang Jiong Li Xiangrong Song Lunzhi Dai Chong Chen Jia Geng Maling Gou Lu Chen Haohao Dong Yong Peng Canhua Huang Zhiyong Qian Wei Cheng Changfa Fan Yuquan Wei Zhaoming Su Aiping Tong Shuaiyao Lu Xiaozhong Peng Xiawei Wei | 2022 | Cellular & Molecular Immunology2022，19，5： | 2 |
| 4 | Dissolution-precipitation growth of uniform and clean two dimensional transition metal dichalcogenides显示文摘Two dimensional transition metal dichalcogenides(TMDCs)have attracted much interest and shown promise in many applications.However,it is challenging to obtain uniform TMDCs with clean surfaces,because of the difficulties in controlling the way the reactants are supplied to the reaction in the current chemical vapor deposition growth process.Here,we report a new growth approach called’dissolution-precipitation’(DP)growth,where the metal sources are sealed inside glass substrates to control their feeding to the reaction.Noteworthy,the diffusion of metal source inside glass to its surface provides a uniform metal source on the glass surface,and restricts the TMDC growth to only a surface reaction while eliminating unwanted gas-phase reaction.This feature gives rise to highly uniform monolayer TMDCs with a clean surface on centimeter-scale substrates.The DP growth works well for a large variety of TMDCs and their alloys,providing a solid foundation for the controlled growth of clean TMDCs by the fine control of the metal source. | Zhengyang Cai Yongjue Lai Shilong Zhao Rongjie Zhang Junyang Tan Simin Feng Jingyun Zou Lei Tang Junhao Lin Bilu Liu Hui-Ming Cheng | 2021 | National Science Review2021，8，3： | 2 |

| 7 | Controlled growth of ultrathin ferromagneticβ-MnSe semiconductor显示文摘Two-dimensional(2D)magnetic crystals with intrinsic ferromagnetism are highly desirable for novel spin-electronic devices.However,the controllable synthesis of 2D magnets,especially the direct growth of 2D magnets on substrate surfaces,is still a challenge.Here,we demonstrate the synthesis of ultrathin zinc-blende phase manganese selenide(β-MnSe)nanosheets using the chemical vapor deposition(CVD)technique.The 2Dβ-MnSe crystals exhibit distinct ferromagnetic properties with a Curie temperature of 42.3 K.Density functional theory(DFT)calculations suggest that the ferromagnetic order inβ-MnSe originates from the exchange coupling between the unsaturated Se and Mn atoms.This study presents significant progress in the CVD growth of ultrathin 2D magnetic materials by thinning bulk magnets,and it will pave the way for the building of energy-efficient spintronic devices in the future. | Jingyun Zou Yumeng Yang Dianyi Hu Lixing Kang Chao Zhu Dan Tian Xiaodong Lv Govindan Kutty Yuxi Guo Manzhang Xu Fengyu Li Guo Hong Zheng Liu | 2022 | SmartMat2022，3，3： | 0 |
