| 1 | A New Scheme and Microstructural Model for 3D Full 5-directional Braided Composites显示文摘Three-dimensional(3D) braided composites are a kind of advanced ones and are used in the aeronautical and astronautical fields more widely.The advantages,usages,shortages and disadvantages of 3D braided composites are analyzed,and the possible approach of improving the properties of the materials is presented,that is,a new type of 3D full 5-directional braided composites is developed.The methods of making this type of preform are proposed.It is pointed out that the four-step braiding which is the most possible to realize industrialized production almost has no effect on the composites'properties.By analyzing the simulation model,the advantages of the material compared with the 3D 4-directional and 5-directional materials are presented.Finally,a microstructural model is analyzed to lay the foundation for the future theoretical analysis of these composites. | Zhang Fan,Liu Zhenguo,Wu Zhe,Tao Guoquan School of Aeronautic Science and Engineering,Beijing University of Aeronautics and Astronautics,Beijing 100191,China | 2010 | Chinese Journal of Aeronautics2010，23，1： | 14 |
| 2 | Genetic diversity,population structure,and relationships of apricot(Prunus)based on restriction site-associated DNA sequencing显示文摘Single-nucleotide polymorphisms(SNPs)are the most abundant form of genomic polymorphisms and are widely used in population genetics research.Here,high-throughput sequencing was used to examine the genome-level diversity,population structure,and relationships of apricot,which are important for germplasm conservation and molecular breeding.Restriction site-associated DNA sequencing(RAD-seq)was adopted to sequence 168 Prunus spp.accessions distributed in five ecological groups,including 74 accessions of cultivated Prunus armeniaca L.and 94 accessions of wild apricots(P.armeniaca L.and Prunus sibirica L.),which generated 417,961 high-quality SNPs.We used cluster,genetic structure,and principal component analyses to examine the genetic diversities and genetic relationships of the 168 accessions.The Dzhungar-Ili ecological group accessions showed the highest genetic diversity in terms of private allele number,observed heterozygosity,and nucleotide diversity.We speculate that the Central Asian ecological group accessions were domesticated from the Dzhungar-Ili ecological group accessions.The population structure and gene flow of the North China and European ecological group accessions suggested a genetic background of P.sibirica.We argue that the two groups should be considered hybrid swarms connected to P.sibirica by continuous and extensive gene flow.P.armeniaca originated in Northwest China(Ili Valley),subsequently spread throughout Central Asia,and eventually spread to Europe.In addition,selective sweep signatures in P.armeniaca during domestication from wild to cultivated apricots,combined with differentially expressed genes,underlie distinct fruit traits,including sugars,aromas,organic acids,and carotenoids.This study provides substantive and valuable genomic resources that will significantly advance apricot improvement and effective utilization. | Wenwen Li Liqiang Liu Yanan Wang Qiuping Zhang Guoquan Fan Shikui Zhang Yatong Wang Kang Liao | 2020 | Horticulture Research2020，7，1： | 9 |
| 3 | New lysine-acetylated proteins screened by immunoaffinity and liquid chromatography-mass spectrometry显示文摘The lack of selective extraction specific for lysine-acetylated proteins has been a major problem in the field of acetylation biology,though acetylation plays a key role in many biological processes.In this paper,we report for the first time the proteomic screening of lysine-acetylated proteins from a mouse liver tissue,by a new approach of immunoaffinity purification of lysine-acetylated peptides combined with nano-HPLC/MS/MS analysis.We have found 20 lysine-acetylated proteins with 21 lysine-acetylated sites,among which 12 lysine-acetylated proteins and 16 lysine-acetylated sites have never been reported before.Notably,three acetyltransferases harboring in mitochondrion are newly discovered acetyltransferases responsible for the acetylation of nonhistone proteins.We have explored the significant patterns of residue preference by the hierarchical clustering analysis of amino acid residues surrounding acetylation sites,which could be helpful to the prediction of new sites of lysine acetylation.Our findings provide more candidates for studying the important roles played by acetylation in diverse cellular pathways and related human diseases. | ZHANG Bing ZHAO Chao LUO KaiXuan YAN GuoQuan YAO Jun WANG YingYin LU HaoJie FAN HuiZhi YANG PengYuan | 2010 | Science China Chemistry2010，53，1： | 1 |
| 4 | Complete genome sequence of a novel bacteriophage infecting Bradyrhizobium diazoefficiens USDA110显示文摘Dear Editor,The nitrogen-fixing symbiotic bacteria, rhizobia are the most important beneficial bacteria in soil, as they form nodules with host legume plants to fix nitrogen to maintain soil fertility and facilitate plant growth. Although these bacteria are critically important to agriculture, bacteriophages of rhizobia (rhizobiophages) are commonly present in soils, rhizosphere,and nodules, which have major influences on the composition and population of rhizobia in soils and affect nodulation and nitrogen fixation. Despite the importance of rhizobiophages,only 23 phage full genomes have been sequenced. | Junjie Liu Hao Yu Yong Huang Zhenhua Yu Guoquan Fan Jian Jin Xiaobing Liu Guanghua Wang | 2018 | Science China(Life Sciences)2018，61，1： | 1 |
| 5 | Advances in Research of Garlic Virus Diseases显示文摘Garlic virus infection is an important disease which affects garlic production,with the increasing years of planting,harm of virus is serious year by year,which seriously affect yield and quality of garlic.In order to know the garlic virus effectively,the paper reviewed the research situation of several important garlic virus in virus species,origin,distribution,host range,symptom,route of transmission,classification,genome and detection technique and the prevention technology of garlic viruses.At the same time,prospected several important research aspects of garlic virus in the future. | BAI Yanju 1,ZHANG Wei 1,LI Xuezhan 1,SHEN Yu 1,GAO Yanling 1,FAN Guoquan 1,GENG Hongwei 1,and MENG Xianxin 2 1 Virus-free Seeding Research Institute of Heilongjiang Agricultural Sciences,Harbin 150086,China 2 Crop Breeding Institute of Heilongjiang Academy of Agricultural Sciences,Harbin 150086,China | 2010 | Journal of Northeast Agricultural University(English Edition)2010，17，2： | 1 |
| 6 | Analysis on the Changes in Fruit Quality of ‘Beishan’ Apricots during Storage at Room Temperature显示文摘[Objectives]This study was conducted to understand the changes in fruit quality during storage of local high-quality apricot variety ‘Beishan’ in Xinjiang at room temperature, and to clarify the suitable storage time of the variety. [Methods] Under normal temperature storage conditions, the changes of fruit weight, firmness, soluble solids, titratable acid, soluble sugar, vitamin C and rot rate were observed every day. [Results] With the increase of storage days at room temperature, the fruit weight and firmness of ‘Beishan’ apricots gradually decreased;the contents of titratable acid and vitamin C decreased gradually;and the contents of soluble solids and soluble sugar increased slightly on the 2^(nd) day of storage, and then gradually decreased. The fruit quality began to decline sharply after the 6^(th) day of storage. The fruit began to rot on the 3^(rd) day of storage, and the rot rate was higher than 60% and increased significantly after the 6^(th) day. After the ‘Beishan’ apricots were stored at room temperature until the 6^(th) day, the fruit quality began to decline sharply, and the rot rate exceeded 60%. The suitable storage time at room temperature was about 6 d. [Conclusions] This study provides data support for the research and promotion of the ‘Beishan’ variety. | Guoquan FAN Yatong WANG Zhanghu TANG Shaopeng WANG Tasiheng·Jieensi Shikui ZHANG | 2022 | Agricultural Biotechnology2022，11，5： | 0 |
| 7 | Strengths,Problems,and Recommendations of Potato Staple Food Development in Zhejiang Province显示文摘China launched the potato staple food strategy in 2015.
