| 1 | Evaluation of a granulated formula for the nerve root type and vertebral artery type of cervical spondylosis:a multicenter,single-blind,randomized,controlled,phase Ⅲ clinical trial显示文摘OBJECTIVE:To evaluate the effectiveness and safety of cervical spondylosis formula granules in reducing the symptoms of patients with the nerve root type and the vertebral artery type of cervical spondylosis.METHODS:This was a multicenter, single-blind,randomized, controlled trial.From April 2002 to November 2003, 499 patients were randomly assigned to either the treatment or the control group.The treatment group was orally administered granules prepared with a formula for cervical spondylosis, while the control group was given Jingfukang granules.The treatment course was 1 month for both groups.RESULTS:In patients with the nerve root type of cervical spondylosis, the total effect rate in the treatment group(87.21%) was significantly higher than that in the control group(80.70%, P < 0.01).After the treatment period in both groups, the treatment group had a significantly greater rate of resolution of pain, numbness of the upper limbs, muscle strength of the upper limbs, and fatigue than the control group(all P < 0.05).In patients with the vertebral artery type of cervical spondylosis, the total effect rate in the treatment group(82.07%) was similar to that in the control group(71.21%, P >0.05).After the treatment period in both groups,the treatment group had a significantly greater rate of resolution of weakness of the waist and knees than the control group(P < 0.05).CONCLUSION:The cervical spondylosis formula granules significantly improve numbness, muscle strength, and fatigue, and reduce pain in patients with the nerve root type of cervical spondylosis,and improve the weakness of the waist and knees in patients with the vertebral artery type of cervical spondylosis. | Luo Xiaodong Wang Peng Li Zhe Liang De Huang Feng Liu Jinwen Chen Xinyu Hu Guoheng Fang Suting Zhang Huajian | 2017 | Journal of Traditional Chinese Medicine2017,37,2: | 28 |
| 2 | Changes in China’s lakes: climate and human impacts显示文摘Lakes have played a critical role in providing water and ecosystem services for people and other organisms in China for millennia.However,accelerating climate change and economic boom have resulted in unprecedented changes in these valuable lakes.Using Landsat images covering the entity of the country,we explored the changes in China’s lakes and the associated driving forces over the last 30 years(i.e.mid-1980 s to 2015).We discovered that China’s lakes have changed with divergent regional trends:in the sparsely populated Tibetan Plateau,lakes are abundant and the lake area has increased dramatically from 38596 to46831 km^2(i.e.increased by 8235 km^2,or 21.3%),whereas,in the densely populated northern and eastern regions,lakes are relatively scarce and the lake area has decreased from 36659 to 33657 km^2(i.e.decreased by 3002 km^2,or 8.2%).In particular,severe lake decreases occurred in the Mongolia-Xinjiang Plateau and the Eastern Plain(-2151 km^2).Statistical analyses indicated that climate was the most important factor controlling lake changes in the Tibetan Plateau,the Yun-Gui Plateau and the Northeast Plain.However,the strength of climatic control on lake changes was low in the Eastern Plain and the Mongolia-Xinjiang Plateau,where human activities,e.g.impoldering,irrigation and mining,have caused serious impacts on lakes.Further lake changes will exacerbate regional imbalances between lake resources and population distribution,and thus may increase the risk of water-resource crises in China. | Shengli Tao Jingyun Fang Suhui Ma Qiong Cai Xinyu Xiong Di Tian Xia Zhao Leqi Fang Heng Zhang Jiangling Zhu Shuqing Zhao | 2020 | National Science Review2020,7,1: | 14 |
| 3 | Convergence proof of the DSMC method and the Gas-Kinetic Unified Algorithm for the Boltzmann equation显示文摘This paper investigates the convergence proof of the Direct Simulation Monte Carlo(DSMC) method and the Gas-Kinetic Unified Algorithm in simulating the Boltzmann equation.It can be shown that the particle velocity distribution function obtained by the DSMC method converges to a modified form of the Boltzmann equation,which is the equation of the gas-kinetic unified algorithm to directly solve the molecular velocity distribution function.Their convergence is derived through mathematical treatment.The collision frequency is presented using various molecular models and the local equilibrium distribution function is obtained by Enskog expansion using the converged equation of the DSMC method.These two expressions agree with those used in the unified algorithm.Numerical validation of the converging consistency between these two approaches is illustrated by simulating the pressure driven Poiseuille flow in the slip transition flow regime and the two-dimensional and three-dimensional flows around a circular cylinder and spherical-cone reentry body covering the whole flow regimes from low speed micro-channel flow to high speed non-equilibrium aerothermodynamics. | LI Zhi Hui FANG Ming JIANG XinYu WU JunLin | 2013 | Science China(Physics,Mechanics & Astronomy)2013,56,2: | 10 |
| 4 | MiR-320a downregulation is associated with imatinib resistance in gastrointestinal stromal tumors显示文摘胃肠的 stromal 肿瘤(大意) 是胃肠的道的最普通的间充质的肿瘤之一。尽管 imatinib 改进结果,药抵抗为扩大耐心的幸存仍然是主要问题。药目标的基因变化是为 imatinib 抵抗的已知的机制。然而,它不能 imatinib 抵抗的现象解释所有,并且众多的另外的机制被建议了在各种各样的模型系统说明 imatinib 抵抗。在这研究,我们使用了屏蔽差别的基于反应的数组途径表示了的 SYBR 绿的量的聚合酶链在主要大意病人和 imatinib 抵抗的病人之间的 miRNAs。选择候选人 miRNAs 在 12 个大意病人的一个队被验证。我们发现 miR-320a 的那低表情与 imatinib 抵抗的短时间被相关,并且为 imatinib 抵抗建议了 miR-320a 的潜在的机制。 | Xiaodong Gao Kuntang Shen Cuizhong Wang Jiaqian Ling Hongshan Wang Yong Fang Yuan Shi Yingyong Hou Jin Qin Yihong Sun Xinyu Qin | 2014 | Acta Biochimica et Biophysica Sinica2014,46,1: | 9 |
| 5 | Immobilization of functional nano-objects in living engineered bacterial biofilms for catalytic applications显示文摘Nanoscale objects feature very large surface-area-to-volume ratios and are now understood as powerful tools for catalysis,but their nature as nanomaterials brings challenges including toxicity and nanomaterial pollution.Immobilization is considered a feasible strategy for addressing these limitations.Here,as a proof-of-concept for the immobilization of nanoscale catalysts in the extracellular matrix of bacterial biofilms,we genetically engineered amyloid monomers of the Escherichia coli curli nanofiber system that are secreted and can self-assemble and anchor nano-objects in a spatially precise manner.We demonstrated three scalable,tunable and reusable catalysis systems:biofilm-anchored gold nanoparticles to reduce nitro aromatic compounds such as the pollutant p-nitrophenol,biofilm-anchored hybrid Cd0.9Zn0.1S quantum dots and gold nanoparticles to degrade organic dyes and biofilm-anchored CdSeS@ZnS quantum dots in a semi-artificial photosynthesis system for hydrogen production.Our work demonstrates how the ability of biofilms to grow in scalable and complex spatial arrangements can be exploited for catalytic applications and clearly illustrates the design utility of segregating high-energy nano-objects from injury-prone cellular components by engineering anchoring points in an extracellular matrix. | Xinyu Wang Jiahua Pu Yi Liu Fang Ba Mengkui Cui Ke Li Yu Xie Yan Nie Qixi Mi Tao Li Lingli Liu Manzhou Zhu Chao Zhong | 2019 | National Science Review2019,6,5: | 9 |
| 6 | Expanded endoscopic therapy criteria should be cautiously used in intramucosal gastric cancer显示文摘Objective: Accurate estimation of lymph node metastasis(LNM) in intramucosal gastric cancer is essential to select less invasive treatment options and even avoid surgery. The aim of this study was to evaluate combined clinicopathological features to predict the presence of LNM.Methods: A retrospective review of data from 386 intramucosal gastric cancer patients who underwent gastrectomy with extended lymphadenectomy from 2003 to 2010 was conducted. The mutual relation between clinicopathological characteristics and LNM was analyzed.Results: LNM was detected in 40(10.4%) of the 386 patients. Histological type and vascular or lymphatic invasion presence showed a positive correlation with LNM occurrence by univariate analysis. Multivariate analysis revealed that histological type was the only factor associated with LNM. Combined clinicopathologic characteristics would be more predictable for LNM. We found no LNM when we used combined clinicopathological characteristics conforming to Japanese absolute indications for endoscopic therapy. The LNM rate was as high as 8.7% when Japanese expanded criteria were used. Univariate analysis in cancer conformity to expand endoscopic submucosal dissection(ESD) indication also revealed that the undifferential type was the only significant factor for LNM.Conclusions: It was possible to predict intramucosal gastric cancer cases without LNM using combined clinicopathological characteristic analysis. Extended indication for ESD should be cautiously used for intramucosal gastric cancer patients. | Hongshan Wang Heng Zhang Cong Wang Yong Fang Xuefei Wang Weidong Chen Fenglin Liu Kuntang Shen Xinyu Qin Zhenbin Shen Yihong Sun | 2016 | Chinese Journal of Cancer Research2016,28,3: | 8 |
| 7 | Growth and characterization of 0.8-μm gate length AlGaN/GaN HEMTs on sapphire substrates显示文摘AlGaN/GaN high electron mobility transistor (HEMT) structures were grown on 2 inch sapphire substrates by MOCVD, and 0.8-μm gate length devices were fabricated and measured. It is shown by resistance mapping that the HEMT structures have an average sheet resistance of approximately 380 ?/sq with a uniformity of more than 96%. The 1-mm gate width devices using the materials yielded a pulsed drain current of 784 mA/mm at Vgs=0.5 V and Vds=7 V with an extrinsic transconductance of 200 mS/mm. A 20-GHz unity current gain cutoff frequency (?T ) and a 28-GHz maximum oscillation frequency (?max) were obtained. The device with a 0.6-mm gate width yielded a total output power of 2.0 W/mm (power density of 3.33 W/mm) with 41% power added efficiency (PAE) at 4 GHz. | WANG Xiaoliang WANG Cuimei HU Guoxin WANG Junxi RAN Junxue FANG Cebao LI Jianping ZENG Yiping LI Jinmin LIU Xinyu LIU Jian QIAN He | 2005 | Science in China(Series F)2005,48,6: | 7 |
| 8 | Li/LiFePO_4 battery performance with a guanidinium-based ionic liquid as the electrolyte显示文摘A new guanidinium-based ionic liquid (IL) was investigated as a novel electrolyte for a lithium rechargeable battery. The viscosity, conductivity, lithium redox behavior, and charge-discharge characteristics of the lithium rechargeable batteries were investigated for the IL electrolyte with 0.3 mol kg 1 lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) salt. Li/ LiFePO 4 cells incorporating the IL electrolyte without additives showed good cycle properties at a charge-discharge current rate of 0.1 C, and exhibited good rate capabilities in the presence of a mass fraction of 10% vinylene carbonate or gamma-butyrolactone. | ZHANG XinYue FANG ShaoHua ZHANG ZhengXi YANG Li | 2011 | Chinese Science Bulletin2011,56,27: | 6 |
| 9 | Abrupt Climate Changes of Holocene显示文摘This paper is a review of studies of abrupt climate changes(ACCs) during the Holocene published during the past ten years.North Atlantic cold events are indicators of ACCs.As indicated by North Atlantic ice-rafted debris(IRD),there were nine confirmed cold events during the Holocene,occurring at 11.1 kyr,10.3 kyr,9.4 kyr,8.1 kyr,5.9 kyr,4.2 kyr,2.8 kyr,1.4 kyr,and 0.4 kyr respectively according to most representative results from Bond et al.(1997).However,the identification of chronology has been made with some uncertainties.Considerable climatic proxy data have shown that,during the cold events,substantial climate abnormalities have occurred widely across the globe,particularly in the areas surrounding the North Atlantic.These abnormalities were in the form of high-latitude cold in the both hemispheres,expansion of the Westerlies to low latitudes,drought in the monsoon regions,recession of summer monsoons,and intensification of the winter monsoons.Studies have indicated that the four ACCs occurring in the early Holocene may be related to freshwater pulses from ice melting in the northern part of the North Atlantic,and the other five ACCs that occurred during the middle and late Holocene may be related to the decreased solar activity. | WANG Shaowu GE Quansheng WANG Fang WEN Xinyu HUANG Jianbin | 2013 | Chinese Geographical Science2013,23,1: | 6 |
| 10 | Rapamycin promotes Schwann cell migration and nerve growth factor secretion显示文摘Rapamycin, similar to FK506, can promote neural regeneration in vitro. We assumed that the mechanisms of action of rapamycin and FK506 in promoting peripheral nerve regeneration were similar. This study compared the effects of different concentrations of rapamycin and FK506 on Sc hwann cells and investigated effects and mechanisms of rapamycin on improving peripheral nerve regeneration. Results demonstrated that the lowest rapamycin concentration(1.53 nmol/L) more significantly promoted Schwann cell migration than the highest FK506 concentration(100 μmol/L). Rapamycin promoted the secretion of nerve growth factors and upregulated growth-associated protein 43 expression in Schwann cells, but did not significantly affect Schwann cell proliferation. Therefore, rapamycin has potential application in peripheral nerve regeneration therapy. | Fang Liu Haiwei Zhang Kaiming Zhang Xinyu Wang Shipu Li Yixia Yin | 2014 | Neural Regeneration Research2014,9,6: | 6 |
| 11 | Preparation and Characterization of Waterborne Polyurethane/Cellulose Nanocrystal Composite Membrane from Recycling Waste Paper显示文摘Cellulose plays a key role in abundant organic natural materials meeting the increasing demand for green and biocompatible products.The highly crystalline nanoscale component of cellulose nanocrystals has recently attracted great attention due to the versatile performance as filler or matrix in producing functional materials.In this work,we prepared the waterborne polyurethane via a prepolymer process,and obtained cellulose and cellulose nanocrystals from waste paper via a facile acid hydrolysis process.After that,the cellulose nanocrystals were assembled into film and mixed with polyurethane to prepare flexible polyurethane/cellulose nanocrystals composite membrane with different soaking time.The correlation between the bulk structure and applied properties including thermal resistance and mechanical property was investigated by using Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),scanning electron microscopy(SEM),thermogravimetric analysis(TGA),differential scanning calorimetry(DSC)and folding test.The structure analysis indicates that cellulose nanocrystals prepared from used paper have a quality similar to that of commercial cellulose.Meanwhile,the cellulose nanocrystals have been mixed with polyurethane uniformly.Polyurethane can significantly benefit to the thermal resistance and mechanical property of the cellulose nanocrystals film.The polyurethane/cellulose nanocrystals composite membrane present good flexibility and may hold a significantly potential application as visual and flexible material. | Xing Zhou Xin Zhang Dong Wang Changqing Fang Wanqing Lei Zhigang Huang Yonghua Song Xinyu He Yingwei Huang | 2020 | Journal of Renewable Materials2020,8,6: | 5 |

| 13 | The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus. | Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang | 2016 | Science China(Life Sciences)2016,59,9: | 5 |

| 15 | Association of the HTR2C-759CT polymorphism and antipsychotic-induced weight gain:a meta-analysis显示文摘Background Antipsychotic-induced weight gain(AIWG)is a crucial factor for the medication cessation of patients with schizophrenia.Multiple studies have shown that the functional polymorphism-759 C/T(rs3813929)in the HTR2C promoter region could possibly be correlated with AIWG.Aim To evaluate the genetic association of the HTR2C-759C/T polymorphism and AIWG in patients with schizophrenia with antipsychotic drugs(APDs)administration.Methods Eligible studies were identified by searching the following databases:PubMed,Embase,Web of Science,China Nation Knowledge Infrastructure(CNKI),VIP,Wanfang Data,Chinese Biomedical Literature Database(CBM)and the Airiti Library.The quality of studies was evaluated based on the Newcastle-Ottawa Scale.The pooled OR and 95%Cl were calculated for the dominant(CT/TT/T vs CC/C)mode,and subgroup analyses were performed based on ethnicity,antipsychotic medication and gender;ail statistical analyses were performed using the statistical software STATA V.12.0.Result A total of 17 studies with 3170 patients with schizophrenia were included in our meta-analysis.The result of the meta-analysis has shown that the association between the-759 C/T polymorphism and AIWG is statistically significant(OR 0.34,95%Cl:0.20 to 0.57,z=4.11,p<0.001).The subgroup analyses revealed significant correlations between the-759 C/T polymorphism and AIWG in the Caucasian population(OR 0.33,95%CI:0.14 to 0.77,z=2.55,p=0.011),the Asian population(OR 0.31,95%Cl:0.18 to 0.52,z=4.46,p<0.001),the patients with APDs administration(CT/JTfJ vs CC/C:OR 0.63,95%Cl:0.40 to 1.00,z=1.97,p=0.049)and the patients with atypical antipsychotic drug administration(CT/TT/T vs CC/C:OR 0.21,95%Cl:0.09 to 0.47,z=3.83,p<0.001).The sensitivity analysis showed that the results were stable.Begg's test(after correction z=1.07,p=0.287)and Egger's test(t=-2.41,p=0.029)show that the included articles have no significant publication bias.Conclusion There is a significant genetic association between HTR2C-759C/T and AIWG,and patients with T allele are less likely to have AIWG. | Yan Chen Yewei Wang Xinyu Fang Yi Zhang Lisheng Song Chen Zhang | 2020 | General Psychiatry2020,33,3: | 4 |
| 16 | Freestanding reduced graphene oxide/sodium vanadate composite films for flexible aqueous zinc-ion batteries显示文摘With the booming development of portable and wearable electronic devices, flexible energy storage devices have attracted great attention. Among various energy storage devices, aqueous zinc ion batteries(ZIBs) are one of the promising candidates due to their low cost, good safety, high energy and power densities. However, the conventional cathodes of aqueous ZIBs were often prepared by mixing active materials with binders and conductive additives and then coating them onto current collectors. The resultant cathodes often suffer from unsatisfied flexibility. Herein, we fabricated freestanding reduced graphene oxide/NaV_3O_8·1.5H_2O(RGO/NVO) composite films with interlinked multilayered architecture by a vacuum filtrating process. Such composite films exhibit excellent mechanical property and high electronic conductivity. Owing to unique architecture, they display a high capacity of 410 mA h g^(-1) and excellent cycling performance up to 2000 cycles with a high capacity retention of 94%. Moreover, RGO/NVO composite films can directly serve as the cathodes of flexible aqueous ZIBs. As a proof of concept,flexible ZIBs were assembled based on the composite films. Impressively, they exhibit stable performance at different bending states, demonstrating great potential application in flexible energy storage devices. | Fang Wan Xinyu Wang Songshan Bi Zhiqiang Niu Jun Chen | 2019 | Science China Chemistry2019,62,5: | 4 |
| 17 | Postsynthetic functionalization of covalent organic frameworks显示文摘Covalent organic frameworks(COFs)have been at the forefront of porous-material research in recent years.With predictable structural compositions and controllable functionalities,the structures and properties of COFs could be controlled to achieve targeted materials.On the other hand,the predesigned structure of COFs allows fruitful postsynthetic modifications to introduce new properties and functions.In this review,the postsynthetic functionalizations of COFs are discussed and their impacts towards structural qualities and performances are comparatively elaborated on.The functionalization involves the formation of specific interactions(covalent or coordination/ionic bonds)and chemical reactions(oxidation/reduction reaction)with pendant groups,skeleton and reactive linkages of COFs.The chemical stability and performance of COFs including catalytic activity,storage,sorption and opto-electronic properties might be enhanced by specific postsynthetic functionalization.The generality of these strategies in terms of chemical reactions and the range of suitable COFs places them as a pivotal role for the development of COF-based smart materials. | Yusran Yusran Xinyu Guan Hui Li Qianrong Fang Shilun Qiu | 2020 | National Science Review2020,7,1: | 4 |
| 18 | Predictions of NOx/N2O emissions from an ultra-supercritical CFB boiler using a 2-D comprehensive CFD combustion model显示文摘NOx and N2O emissions from an ultra-supercritical circulating fluidized bed(CFB)boiler were predicted using a two dimensional(2-D)comprehensive computational fluid dynamics(CFD)combustion model.This model was developed from a three dimensional model for a supercritical CFB boiler previously constructed by our group.Based on an analysis of the NOx and N2O conversion processes in a CFB boiler,the primary formation and destruction reactions were introduced into the 2-D model and coupled.The resulting model was validated using data from the Baima 600 MW supercritical CFB boiler,and then applied to a 660 MW ultra-supercritical CFB boiler.The effects of excess air,the secondary air(SA)to(primary air(PA)plus SA)ratio and the SA injection height on NOx and N2O emissions were investigated.The results show that a higher excess air volume increases both NOx and N2O emissions,while increasing the SA/(PA+SA)ratio somewhat reduces both the NOx and N2O concentrations.On the basis of the results of this work,optimal locations for SA injection ports so as to lower NOx and N2O emissions are recommended. | Jieqiang Ji Leming Cheng Yangjun Wei Junfeng Wang Xinyu Gao Mengxiang Fang Qinhui Wang | 2020 | Particuology2020,18,2: | 4 |
| 19 | Reversible N6-methyladenosine of RNA:The regulatory mechanisms on gene expression and implications in physiology and pathology显示文摘N6-methyladenosine(m6A)is the most abundant inner RNA modification in eukaryotes.Due to the development of RNA sequencing technology,the distribution pattern of m6A in the transcriptome has been uncovered.Dynamically,the reversible N6-methylation is mediated by two types of proteins,which are classified as“writers”and“erasers”.Under the association of specific co-factors,writers show spatiotemporal N6-methyltransferase activity.Mechanically,m6A can be recognized by“reader”proteins or can directly modify RNA conformation,and it widely affects gene expression by mediating RNA stability,translation,splicing and export.m6A is involved in a series of physiology processes.Dysregulation of m6A is gradually defined as the pathogenesis of some diseases,e.g.,cancer and cardiovascular disease.Therefore,a good understanding of m6A is essential for molecular biology and pathology research.In this article we systemically present an overview of the functions and mechanisms of identified m6A regulators.The discovered biological and pathological processes affected by m6A are also summarized.We hope that readers with related research interests benefit from our review. | Xinyu Fang Mengyang Li Tao Yu Gaoli Liu Jianxun Wang | 2020 | Genes & Diseases2020,7,4: | 4 |
| 20 | The complete reference genome for grapevine (Vitis vinifera L.) genetics and breeding显示文摘Grapevine is one of the most economically important crops worldwide.However,the previous versions of the grapevine reference genome tipically consist of thousands of fragments with missing centromeres and telomeres,limiting the accessibility of the repetitive sequences,the centromeric and telomeric regions,and the study of inheritance of important agronomic traits in these regions.Here,we assembled a telomere-to-telomere(T2T)gap-free reference genome for the cultivar PN40024 using PacBio HiFi long reads.The T2T reference genome(PN_T2T)is 69 Mb longer with 9018 more genes identified than the 12X.v0 version.We annotated 67%repetitive sequences,19 centromeres and 36 telomeres,and incorporated gene annotations of previous versions into the PN_T2T assembly.We detected a total of 377 gene clusters,which showed associations with complex traits,such as aroma and disease resistance.Even though PN40024 derives from nine generations of selfing,we still found nine genomic hotspots of heterozygous sites associated with biological processes,such as the oxidation–reduction process and protein phosphorylation.The fully annotated complete reference genome therefore constitutes an important resource for grapevine genetic studies and breeding programs. | Xiaoya Shi Shuo Cao Xu Wang Siyang Huang Yue Wang Zhongjie Liu Wenwen Liu Xiangpeng Leng Yanling Peng Nan Wang Yiwen Wang Zhiyao Ma Xiaodong Xu Fan Zhang Hui Xue Haixia Zhong Yi Wang Kekun Zhang Amandine Velt Komlan Avia Daniela Holtgräwe Jérôme Grimplet JoséTomás Matus Doreen Ware Xinyu Wu Haibo Wang Chonghuai Liu Yuling Fang Camille Rustenholz Zongming Cheng Hua Xiao Yongfeng Zhou | 2023 | Horticulture Research2023,10,5: | 3 |
