| 1 | High-resolution Remote Sensing Image Semi-global Matching Method Considering Geometric Constraints of Connection Points and Image Texture Information显示文摘Dense matching of remote sensing images is a key step in the generation of accurate digital surface models.The semi-global matching algorithm comprehensively considers the advantages and disadvantages of local matching and global matching in terms of matching effect and computational efficiency,so it is widely used in close-range,aerial and satellite image matching.Based on the analysis of the original semi-global matching algorithm,this paper proposes a semi-global high-resolution remote sensing image that takes into account the geometric constraints of the connection points and the image texture information based on a large amount of high-resolution remote sensing image data and the characteristics of clear image texture.123123The method includes 4 parts:①Precise orientation.Aiming at the system error in the image orientation model,the system error of the rational function model is compensated by the geometric constraint relationship of the connecting points between the images,and the sub-pixel positioning accuracy is obtained;②Epipolar image generation.After the original image is divided into blocks,the epipolar image is generated based on the projection trajectory method;③Image dense matching.In order to reduce the size of the cost space and calculation time,the image is pyramided and then semi-globally matched layer by layer.In the matching process,the disparity map expansion and erosion algorithm that takes into account the image texture information is introduced to restrict the disparity search range and better retain the edge characteristics of the ground objects;④Generate DSM.In order to test the matching effect,the weighted median filter algorithm is used to filter the disparity map,and the DSM is obtained based on the principle of forward intersection.Finally,the paper uses the matching results of WordView3 and Ziyuan No.3 stereo image to verify the effectiveness of this method. | Jingguo LV Xingbin YANG Danlu ZHANG Shan JIANG | 2021 | Journal of Geodesy and Geoinformation Science2021，4，4： | 4 |

| 4 | An Effective Platform for Exploring Rotavirus Receptors by Bacterial Surface Display System显示文摘Rotavirus(RV) is a major foodborne pathogen. For RV prevention and control, it is a key to uncover the interaction mechanism between virus and its receptors. However, it is hard to specially purify the viral receptors, including histo-blood group antigens(HBGAs). Previously, the protruding domain protein(P protein) of human norovirus(genotype Ⅱ.4) was displayed on the surface of Escherichia coli, and it specifically recognized and captured the viral ligands. In order to further verify the feasibility of the system, P protein was replaced by VP8* of RV(G9 P[8]) in this study. In the system, VP8*could be correctly released by thrombin treatment with antigenicity retaining, which was confirmed by Western blot and Enzyme-Linked Immunosorbent Assays. Type A HBGAs from porcine gastric mucin(PGM) were recognized and captured by this system. From saliva mixture, the captured viral receptor bound with displayed VP8* was confirmed positive with monoclonal antibody against type A HBGAs. It indicated that the target ligands could be easily separated from the complex matrix. These results demonstrate that the bacterial surface display system will be an effective platform to explore viral receptors/ligands from cell lines or food matrix. | Danlei Liu Haoran Geng Zilei Zhang Yifan Xing Danlu Yang Zhicheng Liu Dapeng Wang | 2020 | Virologica Sinica2020，35，1： | 1 |

| 7 | An endolysin gene from Candidatus Liberibacter asiaticus confers dual resistance to huanglongbing and citrus canker显示文摘The most damaging citrus diseases are Huanglongbing(HLB)and citrus canker,which are caused by Candidatus Liberibacter asiaticus(CaLas)and Xanthomonas citri pv.citri(Xcc),respectively.Endolysins from bacteriophages are a possible option for disease resistance in plant breeding.Here,we report improvement of citrus resistance to HLB and citrus canker using the LasLYS1 and LasLYS2 endolysins from CaLas.LasLYS2 demonstrated bactericidal efficacy against several Rhizobiaceae bacteria and Xcc,according to inhibition zone analyses.The two genes,driven by a strong promoter from Cauliflower mosaic virus,35S,were integrated into Carrizo citrange via Agrobacterium-mediated transformation.More than 2 years of greenhouse testing indicated that LasLYS2 provided substantial and long-lasting resistance to HLB,allowing transgenic plants to retain low CaLas titers and no obvious symptoms while also clearing CaLas from infected plants in the long term.LasLYS2 transgenic plants with improved HLB resistance also showed resistance to Xcc,indicating that LasLYS2 had dual resistance to HLB and citrus canker.A microbiome study of transgenic plants revealed that the endolysins repressed Xanthomonadaceae and Rhizobiaceae populations in roots while increasing Burkholderiaceae and Rhodanobacteraceae populations,which might boost the citrus defense response,according to transcriptome analysis.We also found that Lyz domain 2 is the key bactericidal motif of LasLYS1 and LasLYS2.Four endolysins with potential resistance to HLB and citrus canker were found based on the structures of LasLYS1 and LasLYS2.Overall,the work shed light on the mechanisms of resistance of CaLas-derived endolysins,providing insights for designing endolysins to develop broad-spectrum disease resistance in citrus. | Lanzhen Xu Kaiqing Mo Danlu Ran Juanjuan Ma Lehuan Zhang Yijia Sun Qin Long Guojin Jiang Xiaochun Zhao Xiuping Zou | 2023 | Horticulture Research2023，10，9： | 0 |
