| 1 | A Chromosome-Scale Genome Assembly of Paper Mulberry(Bmussonetia papyrifera)Provides New Insights into Its Forage and Papermaking Usage显示文摘Paper mulberry(Broussonetia papyrifera)is a well-known woody tree historically used for Cai Lun papermaking,one of the four great inventions of ancient China.More recently,Paper mulberry has also been used as forage to address the shortage of feedstuff because of its digestible crude fiber and high protein contents.In this study,we obtained a chromosome-scale genome assembly for Paper mulberry using integrated approaches,including Illumina and PacBio sequencing platform as well as Hi-C,optical,and genetic maps.The assembled Paper mulberry genome consists of 386.83 Mb,which is close to the estimated size,and 99.25%(383.93 Mb)of the assembly was assigned to 13 pseudochromosomes.Comparative genomic analysis revealed the expansion and contraction in the flavonoid and lignin biosynthetic gene families,respectively,accounting for the enhanced flavonoid and decreased lignin biosynthesis in Paper mulberry.Moreover,the increased ratio of syringyl-lignin to guaiacyl-lignin in Paper mulberry underscores its suitability for use in medicine,forage,papermaking,and barkcloth making.We also identified the rootassociated microbiota of Paper mulberry and found that Pseudomonas and Rhizobia were enriched in its roots and may provide the source of nitrogen for its stems and leaves via symbiotic nitrogen fixation.Collectively,these results suggest that Paper mulberry might have undergone adaptive evolution and recruited nitrogen-fixing microbes to promote growth by enhancing flavonoid production and altering lignin monomer composition.Our study provides significant insights into genetic basis of the usefulness of Paper mulberry in papermaking and barkcloth making,and as forage.These insights will facilitate further domestication and selection as well as industrial utilization of Paper mulberry worldwide. | Xianjun Peng Hui Liu Peilin Chen Feng Tang Yanmin Hu Fenfen Wang Zhi Pi Meiling Zhao Naizhi Chen Hui Chen Xiaokang Zhang Xueqing Yan Min Liu Xiaojun Fu Guofeng Zhao Pu Yao Lili Wang He Dai Xuming Li Wei Xiong Wencai Xu Hongkun Zheng Haiyan Yu Shihua Shen | 2019 | Molecular Plant2019，12，5： | 18 |
| 2 | Short-working-distance optical imaging system and method for surface detection of underwater structures显示文摘In the surface imaging of underwater structures, long working distance will reduce image quality due to the turbidity of water. To acquire high definition and large field of view(FOV) images for surface detection, a short-working-distance underwater imaging system is proposed based on camera array. A multi-view calibration and rectification method is developed. A look-up table(LUT) method and a multi-resolution spline(MRS) method are applied to stitch array images real-time and seamlessly.Experiments both in the air and in the water are conducted. Strength and weakness of the LUT and MRS methods are discussed.Based on the results, the effectiveness in surface detection of underwater structures is verified. | LIU Cong WANG ChengFei XU YingJun LI Xu LUO ChunHao DAI MeiLing SHAO XinXing HE XiaoYuan | 2018 | Science China(Technological Sciences)2018，61，5： | 4 |
| 3 | Genetic Analysis and Mapping of the Purple Gene in Purple Heading Chinese Cabbage显示文摘To analyze genetic linkage and map purple gene(Br Pur) controlling purple inner leaves trait of Chinese cabbage, a F2 population was constructed by selfing a F1 plant from homozygous purple heading line ‘14S839' and homozygous orange heading line ‘14S162'. The phenotype investigation of head color showed that the segregation ratio of purple to non-purple individuals was consistent with the expected ratio of 3:1,which indicated that purple inner leaves trait is controlled by a single dominant gene. A total of 297 SSRs in whole genome of Chinese cabbage were tested by modified Bulked Segregant Analysis(BSA) method. Two linked markers flanking Br Pur, A710 and A714, were obtained and Br Pur was mapped on linkage group A07 based on the sequence of these two markers. Subsequently, two new markers flanking Br Pur, CL-12 and B214-87, were developed based on two known anthocyanins-related genes, Br4CL3 and Bra004214. Genetic mapping of all markers in the F2 mapping population showed CL-12 and B214-87 linked to Br Pur with the genetic distance of 3.1 c M and 3.5 c M, respectively. | WU Junqing ZHAO Jing QIN Meiling REN Yanjing ZHANG Huamin DAI Zihui HAO Lingyu ZHANG Lugang | 2016 | Horticultural Plant Journal2016，2，6： | 3 |
| 4 | Blockchain-Based Reliable Fog-Cloud Service Solution for IIoT显示文摘Industrial Internet of things(IIoT)deploys a large number of smart devices to obtain industrial data,which will be transmitted to cloud for analysis to improve industrial productivity.The management of large-scale devices is complicated,and it’s also a challenge to choose a high-quality cloud service for data analysis as the number of service with similar functions increases.To address these issues,we propose a reliable fog-cloud service solution with blockchain-based fog-cloud architecture.In fog layer,we build a management blockchain between fog servers and design a management method for industrial devices;In cloud layer,we construct a service blockchain between cloud service providers to form an open'service market'.Quality of service and reputation based matching algorithm and reputation-based consensus algorithm are designed.The simulation results show correctness and efficiency of algorithms,and validate effectiveness of our proposed solution. | DAI Meiling XU Siya SHAO Sujie GUO Shaoyong QIU Xuesong XIONG Ao | 2021 | Chinese Journal of Electronics2021，30，2： | 3 |
| 5 | High-pressure investigations on the isostructural phase transition and metallization in realgar with diamond anvil cells显示文摘The high-pressure structural,vibrational and electrical properties for realgar were investigated by in-situ Raman scattering and electrical conductivity experiments combined with first-principle calculations up to~30.8 GPa.It was verified that realgar underwent an isostructural phase transition at~6.3 GPa and a metallization at a higher pressure of~23.5 GPa.The isostructural phase transition was well evidenced by the obvious variations of Raman peaks,electrical conductivity,crystal parameters and the As–S bond length.The phase transition of metallization was in closely associated with the closure of bandgap rather than caused by the structural phase transition.And furthermore,the metallic realgar exhibited a relatively low compressibility with the unit cell volume V_(0)=718.1.4Å^(3)and bulk modulus B_(0)=36.1 GPa. | Linfei Yang Lidong Dai Heping Li Haiying Hu Meiling Hong Xinyu Zhang Pengfei Liu | 2021 | Geoscience Frontiers2021，12，2： | 1 |
| 6 | Nitrogen-doped TiO_(2)/Graphene Composites Synthesized via the Vapour-thermal Method显示文摘TiO_(2)/graphene composite was synthesized in the vapor environment of isopropanol.In order to improve the properties of composite,N-doped of TiO_(2)/graphene with different N/Ti molar ratio was prepared in the vapor environment of deionized water and used urea as the source of nitrogen.The N-doped occupies in the interstitial sites of TiO_(2) lattice,substitutes for O element in TiO_(2) and for C element in graphene,and simultaneously changes the chemical states of Ti and O elements in TiO_(2).N-doped changes the morphology of TiO_(2) from nano-sheets to nanoparticles,accompanying with the decrease in specific surface area of the composites,first increases the particle size of TiO_(2) and then decreases,and alters the vibration modes of Ti-OTi.The composite with RN/Ti=2 exhibits the enhanced photocatalytic degradation performance to methylene blue,and the degradation rate increases from 7.7×10^(−2) min^(−1) for the undoped composite to 9.6×10^(−2) min^(−1). | 唐海龙 王敏 JU Tangtong DAI Yue WANG Meiling MA Yongqing ZHENG Ganhong | 2022 | Journal of Wuhan University of Technology(Materials Science)2022，37，6： | 0 |
| 7 | Burning magnesium in carbon dioxide for highly effective phosphate removal显示文摘Magnesium oxide was found to have high-phosphate-affinity as an effective component to enhance the phosphate removal ability of common adsorbent materials.However,the currently prepared MgO-based hybrid adsorbents by conventional methods still suffer from the limited low loading of MgO and inferior removal performances,much far away from practical application.In this study,an ingenious carbon coated MgO nanocomposite is designed by directly burning magnesium in CO_(2),a well-known textbook reaction.X-ray diffraction analysis,scanning electron microscope and aberration-corrected high-resolution transmission electron microscope demonstrate the sample is well prepared.Consequently,the high content of nanosized MgO combined with defect-rich carbon layer brings unprecedented phosphate removal capacity of 1135.0 mg/g,removal rate of 99% and benign compatibility with coexisting anions and solution pH.Furthermore,the removal mechanism is also investigated in detail by characterizing the sample before and after adsorption. | Ying Yao Lei Yu Meiling Wang Alvin Dai Yan Zhang Qiubo Guo Yulin Lin JianguoWen Feng Wu Xiulei Ji Jun Lu | 2021 | Carbon Energy2021，3，2： | 0 |

| 9 | Sialoglycoproteins Isolated from the Eggs of Gadus morhua Inhibit Bone Resorption in Ovariectomized Rats by Suppressing the MAPK and NF-κB Pathways显示文摘The present study investigated the anti-osteoporosis function and the mechanism of sialoglycoproteins isolated from the eggs of Gadus morhua(Gm-SGP)on ovariectomized(OVX)rats.After 3 months of Gm-SGP treatment,OVX-induced bone loss was suppressed and uncoupling bone turnover was balanced,as indicated by systemic biomarkers of bone metabolism;no uterine estrogenicity was observed.Moreover,rats administered with Gm-SGP exhibited increased bone mineral density and biomechanical strength and significant restoration of the trabecular microarchitecture compared with rats in the control group.Gm-SGP significantly decreased bone resorption-related indicators in serum.Investigation of the associated mechanisms revealed that Gm-SGP significantly increases the OPG/RANKL ratio at the mRNA and protein levels.Further research suggested that Gm-SGP inhibits the mRNA and protein expressions of important transcription factors of the MAPK and NF-κB signaling pathways.It also attenuates the activation of related transduction signaling pathways by inhibiting phosphorylation of JNK,ERK,p38,and NF-κB,and ultimately suppresses the induction of c-Fos and NFATc1.Overall,these results demonstrate that Gm-SGP inhibits bone resorption by suppressing osteoclastogenesis-related MAPK and NF-κB pathways,thereby improving osteoporosis. | MAO Lei WANG Yiming WANG Meiling DAI Yufeng WANG Jingfeng XUE Changhu | 2019 | Journal of Ocean University of China2019，18，5： | 0 |
