| 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 |

| 3 | Original position statistic distribution analysis study of low alloy steel continuous casting billet显示文摘The homogeneity of low alloy steels continuous casting billet obtained under different technological conditions has been investigated by original position statistic distribution analysis technique. On the basis of systematic analysis of ten thousands primary optical signals at the corresponding original positions, the quantitative statistic distribution information of each element was obtained. The biggest degrees of segregation of low alloy steel continuous casting billet were calculated accurately according to the quantitative distribution maps of the contents. It was suggested that the weight ratio in a certain content range was used to judge the homogeneity of the materials, and the two models —— the total weight ratio of contents (the degree of statistic homogeneity, H) within the permissive content range (C0±R) and the median value confidence extension ratio (the degree of statistic segregation, S) at 95% of confidence limit of weight ratio —— were put forward. The two models reflect the composition and state distribution regularity of the metal materials in a large region. The difference between the sample with high columnar crystal and the sample with high equiaxed crystal has been studied by using the two models. | WANG Haizhou ZHAO Pei CHEN Jiwen LI Meiling YANG Zhijun WU Chao | 2005 | Science China(Technological Sciences)2005，48，1： | 13 |
| 4 | Outbreak of human astrovirus 1 lineage 1d in a childcare center in China显示文摘Dear Editor,Astrovirus is an enteric virus associated with sporadic diarrhea or large outbreaks of gastroenteritis(Mendez et al.,2013).Until 2008,human astroviruses(HAst Vs)were classified into eight serotypes—HAstV-1 to HAstV-8—based on the reactivity of their capsid protein with type-specific antibodies.Among these serotypes,HAstV-1is the most prevalent globally.However,some divergent new astroviruses(MLB1/MLB2,VA1/VA2/VA3,and HMO A/B/C)have been discovered recently in | Meiling Hou Xuexue Liang Liqian Tan Pengfei Liu Wei Zhao | 2016 | Virologica Sinica2016，31，3： | 9 |
| 5 | Correlating Fe source with Fe-N-C active site construction: Guidancefor rational design of high-performance ORR catalyst显示文摘Pyrolyzed Fe-N_X/C materials derived from Fe-doped ZIF-8 are recently emerged as promising alternatives to noble metal platinum-based catalysts towards oxygen reduction reaction(ORR) and elucidating the dependacne of Fe source on the active site structure and final ORR performance is highly desirbale for further development of these materials. Here, we designed and synthesized a series of Fe-N-C catalysts using ZIF-8 and various iron salts(Fe(acac)_3, FeCl_3, Fe(NO_3)_3) as precusors. We found that the iron precursors,mainly the molecular size, hydrolysis extent, do play a major role in determining the final morphology of Fe, namely forming the Fe-Nx coordination or Fe_3C nanoparticles, as well as the site density, therefore,significantly affecting the ORR activity. Among the three iron sources, Fe(acac)_3 is most advantageous to the preferential formation of single-atom Fe-Nx active sites and the derived catalyst demonstrated best ORR performance. | Liqin Gao Meiling Xiao Zhao Jin Changpeng Liu Jianbing Zhu Junjie Ge Wei Xing | 2018 | Journal of Energy Chemistry2018，27，6： | 4 |

| 7 | Oxygen-vacancy-rich TiO_(2)enables highly active and durable water electrolysis of urchin-like RuO_(2)catalyst显示文摘The material innovation is prerequisite to accelerating sluggish oxygen evolution reaction(OER)kinetics,thus promoting the realization of hydrogen energy community.Herein,we develop an oxygen-vacancy-rich TiO_(2)supported RuO_(2)catalyst(RuO_(2)@r-TiO_(2))towards improved OER activity and stability.The oxygen vacancy on TiO_(2)not only supplies electrons to produce lower valence Ru,but also provides sufficient anchoring site for the deposition of RuO_(2)nanocrystal.Beyond that,it can generate strong electronic interaction between TiO_(2)and supported RuO_(2),and thereby tailors the intermediates’adsorption energy on the RuO_(2)surface.As a result,the derived RuO_(2)@r-TiO_(2)catalyst exhibits superior OER activity and stability with the overpotential of 211 mV at a current density of 10 mA cm^(−2)and negligible activity degradation after 6 h operation,outperforming the non-oxygen-vacancy counterpart(223.3 mV,12.75%activity loss)and RuO_(2)catalyst(234.6 mV,42.86%activity loss). | GAO HongMei XIAO MeiLing LI GuoQiang GAO LiQin MENG QingLei LUO ZhaoYan LUO ErGui LIU ChangPeng JIN Zhao GE JunJie XING Wei | 2022 | Science China(Technological Sciences)2022，65，10： | 3 |
| 8 | The effects of altered BMP4 signaling in first branchialarch- derived murine embryonic orofacial tissues显示文摘The first branchial arch(BA1),which is derived from cranial neural crest(CNC)cells,gives rise to various orofacial tissues.Cre mice are widely used for the determination of CNC and exploration of gene functions in orofacial development.However,there is a lack of Cre mice specifically marked BA1’s cells.Pax2-Cre allele was previously generated and has been widely used in the field of inner ear development.Here,by compounding Pax2-Cre and R26R-mTmG mice,we found a specific expression pattern of Pax2^(+)cells that marked BA1’s mesenchymal cells and the BA1-derivatives.Compared to Pax2-Cre;R26R-mTmG allele,GFP^(+)cells were abundantly found both in BA1 and second branchial arch in Wnt1-Cre;R26R-mTmG mice.As BMP4 signaling is required for orofacial development,we over-activated Bmp4 by using Pax2-Cre;pMes-BMP4 strain.Interestingly,our results showed bilateral hyperplasia between the upper and lower teeth.We also compare the phenotypes of Wnt1-Cre;pMes-BMP4 and Pax2-Cre;pMes-BMP4 strains and found severe deformation of molar buds,palate,and maxilla-mandibular bony structures in Wnt1-Cre;pMes-BMP4 mice;however,the morphology of these orofacial organs were comparable between controls and Pax2-Cre;pMes-BMP4 mice except for bilateral hyperplastic tissues.We further explore the properties of the hyperplastic tissue and found it is not derived from Runx2^(+)cells but expresses Msx1,and probably caused by abnormal cell proliferation and altered expression pattern of p-Smad1/5/8.In sum,our findings suggest altering BMP4 signaling in BA1-specific cell lineage may lead to unique phenotypes in orofacial regions,further hinting that Pax2-Cre mice could be a new model for genetic manipulation of BA1-derived organogenesis in the orofacial region. | Jue Xu Meiling Chen Yanan Yan Qiaoxue Zhao Meiying Shao Zhen Huang | 2021 | International Journal of Oral Science2021，13，4： | 3 |
| 9 | 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 |
| 10 | Vacuum carburization of 12Cr2Ni4A low carbon alloy steel with lanthanum and cerium ion implantation显示文摘As bearing parts, 12 Cr2 Ni4 A is expected to have high hardness and excellent fatigue strength, so carburizing is employed to improve the inherit properties of 12 Cr2 Ni4 A. However, the traditional carburizing is limited by poor microstructure distribution and low rate of carburizing. The rare earth ion implantation is known to help improving the properties of tribology, corrosion resistance and oxidation resistance of metal. In this article, the RE implantation is employed to assist the carburizing. Lanthanum and cerium ion implantations are initially used to assist 12 Cr2 Ni4 A low pressure vacuum carburization.The microstructure, content of retained austenite, hardness, thickness of layer and carbon diffusion were analyzed by optical microscopy(OM), scanning electron microscopy(SEM), X-ray diffraction(XRD) and Rockwell/Vickers hardness tester, respectively. It was shown that lanthanum and cerium implantations can improve structure of the vacuum carburizing layer, and enhance the uniformity of carbon element distribution on the carburized surface. Meanwhile the RE implantation plays a positive role in promoting the surface hardness and carburized rate. The lanthanum element has more significant effect on surface hardness and content of retained austenite than cerium element. The surface hardness of lanthanum element implanted layer was 62.9 HRC with 9.6% content of retained austenite, while the carburizing rate of cerium implanted layer increased by 12.4%. | Meiling Dong Xiufang Cui Yuhui Zhang Guo Jin Caiwen Yue Xin Zhao Zhaobing Cai Binshi Xu | 2017 | Journal of Rare Earths2017，35，11： | 3 |
| 11 | In vitro expansion of human sperm through nuclear transfer显示文摘Dear Editor,Mammalian haploid embryonic stem cells(haESCs)represent an ideal tool for genetic analysis due to the presence of only one set of genetic materials.HaESCs fall into two readily distinguishable groups based on their genome origins:parthenogenetic haESCs(PG-haESCs)that are derived from oocyte-originated parthenogenetic embryos and androgenetic haESCs(AG-haESCs)that are produced through sperm nuclear transfer.Both PG-and AGhaESCs are feasible for delineating genome function at cellular level in vitro.Importantly,AG-haESCs can be used as a sperm replacement and applied to deciphering gene function at organismal level when combined with CRISPR-Cas9 technology.1 However,while PG-haESCs have been generated from both rodent and primates,2-5 AG-haESCs can only be obtained in rodent to date. | Xiaoyu Merlin Zhang Keliang Wu Yuxuan Zheng Han Zhao Junpeng Gao Zhenzhen Hou Meiling Zhang Jiaoyang Liao Jingye Zhang Yuan Gao Yuanyuan Li Lin Li Fuchou Tang Zi-Jiang Chen Jinsong Li | 2020 | Cell Research2020，30，4： | 3 |
| 12 | Chromosomal-level genome of macadamia(Macadamia integrifolia)显示文摘Macadamia from the family Proteaceae is a plant native to Australia and has long been favoured by people for its crispy and high nutritional and medicinal value.Here,the genome of GUIRE 1(GR1),a highly heterozygous superior cultivar of macadamia nut,was sequenced and assembled using nanopore sequencing,and a 807-Mb genome(contig N50,1.9 Mb;scaffold N50,54.70 Mb)and 14 chromosomes were obtained.A total of 453 Mb(about 55.95%)repetitive sequences and 37,657 protein-coding genes were obtained by gene annotation and homologous protein comparison.Proteaceae diverged from Nelumbonaceae nearly 115.37 million years ago and from Rubiaceae about 140 million years ago.A genome-wide duplication(WGD)event occurred in macadamia 41 million years ago based on the WGD analysis.The functional enrichment analysis of M.integrifolia-specific gene families revealed their roles in signal transduction,protein phosphorylation,protein binding,and defense response.Here,a highly heterozygous genome of M.integrifolia was unlocked to provide a database for breeding and molecular mechanism research. | Chengcai Xia Sirong Jiang Qiujin Tan Wenquan Wang Long Zhao Chenji Zhang Yuting Bao Qi Liu Jianjia Xiao Ke Deng Miaohua He Pengliang An Wenlin Wang Meiling Zou Zhiqiang Xia | 2022 | Tropical Plants2022，1，1： | 3 |

| 14 | Hydrogen etching induced hierarchical meso/micro-pore structure with increased active density to boost ORR performance of Fe-N-C catalyst显示文摘Rational regulation on pore structure and active site density plays critical roles in enhancing the performance of Fe-N-C catalysts. As the microporous structure of the carbon substrate is generally regarded as the active site hosts, its hostility to electron/mass transfer could lead to the incomplete fulfillment of the catalytic activity. Besides, the formation of inactive metallic Fe particles during the conventional catalyst synthesis could also decrease the active site density and complicate the identification of real active site. Herein, we developed a facial hydrogen etching methodology to yield single site Fe-N-C catalysts featured with micro/mesoporous hierarchical structure. The hydrogen concentration in pyrolysis process was designated to effectively regulate the pore structure and active site density of the resulted catalysts.The optimized sample achieves excellent ORR catalytic performance with an ultralow H2O2 yield(1%)and superb stability over 10,000 cycles. Our finding provides new thoughts for the rational design of hierarchically porous carbon-based materials and highly promising non-precious metal ORR catalysts. | Liqin Gao Meiling Xiao Zhao Jin Changpeng Liu Junjie Ge Wei Xing | 2019 | Journal of Energy Chemistry2019，28，8： | 2 |

| 17 | IncR26319/miR-2834/EndophilinA axis regulates oogenesis of the silkworm,Bombyx mori显示文摘Oocyte maturation is critical for insect reproduction.Vitellogenesis,the timely production and uptake of vitellogenin(Vg),is crucial for female fecundity.Vg is synthesized in fat body and absorbed by the oocytes through endocytosis during insect oogenesis.In the silkworm,Bombyx mori,we discovered that a nucleus-enriched long-noncoding RNA(lncRNA)lncR26319 regulates Endophilin A(EndoA)-a member of the endophilin family of endocytic proteins-through competitive binding to miR-2834.The lncR26319-miR-2834-EndoA axis was required for Vg endocytosis in the silkworm;loss of EndoA or overexpression ofmiR-2834significantlyreduced eggnumbers invirginmoths.Inaddition,accumulation of miR-2834 resulted in pupal and adult deformation and reduced fecundity in females.The expression of Vg,30-kDa(30K)protein,and egg-specific protein(Esp)decreased after knockdown of EndoA or overexpression of miR-2834,while knockdown of miR-2834 had an opposite effect on the expression of Vg,30K protein gene,and Esp.These results suggest that the lncR26319-miR-2834-EndoA axis contributes to the endocytic activity in theVguptake and leads to the normal progression of oogenesis in the silkworm.Thus,miR-2834 and EndoA are crucial for female reproduction and could be potential targets for new pest management strategies in lepidopterans. | Yi Wang Yu Fu Hao Chena Chenyue Zhao Qunxia Huang Meiling Chang Wujie Qiu Yawen Shen Dandan Li | 2023 | Insect Science2023，30，1： | 1 |
