| 1 | Lushan M_S7.0 earthquake:A blind reserve-fault event显示文摘In the epicenter of the Lushan MS7.0 earthquake there are several imbricate active reverse faults lying from northwest to southeast,namely the Gengda-Longdong,Yanjing-Wulong,Shuangshi-Dachuan and Dayi faults.Emergency field investigations have indicated that no apparent earthquake surface rupture zones were located along these active faults or their adjacent areas.Only brittle compressive ruptures in the cement-covered pavements can be seen in Shuangshi,Taiping,Longxing and Longmen Townships,and these ruptures show that a local crustal shortening occurred in the region during the earthquake.Combining spatial distribution of the relocated aftershocks and focal mechanism solutions,it is inferred that the Lushan earthquake is classified as a typical blind reverse-fault earthquake,and it is advised that the relevant departments should pay great attention to other historically un-ruptured segments along the Longmenshan thrust belt and throughout its adjacent areas. | XU XiWei WEN XueZe HAN ZhuJun CHEN GuiHua LI ChuanYou ZHENG WenJun ZHNAG ShiMin REN ZhiQun XU Chong TAN XiBin WEI ZhanYu WANG MingMing REN JunJie HE ZhongTai LIANG MingJian | 2013 | Chinese Science Bulletin2013，58，28： | 35 |
| 2 | Rupture segmentation and slip partitioning of the mid-eastern part of the Kunlun Fault,north Tibetan Plateau显示文摘The Kunlun Fault,an active fault on the border between the Bayan Har and Kunlun-Qaidam blocks,is one of the major left lateral strike-slip faults in the Tibetan Plateau.Previous research has not reached a consensus on agreeable slip rates along much of its length and the slip rate gradient along the eastern part,both of which play critical roles in a range of models for the eastward extrusion and thickened crust of the Tibetan Plateau.New slip rates have been determined at sites along the eastern part of the Kunlun Fault by dating deposits and measuring atop displaced fluvial terrace risers.Field investigations and interpretation of satellite images reveal geometrical features of the fault and the late Quaternary offset,new earthquake ruptures and surface-rupturing segmentation,from which long-term slip rates and earthquake recurrence intervals on the fault are estimated.The tectonic geomorphology method has determined that the long-term horizontal slip rates on the Tuosuohu,Maqin and Maqu segments from west to east are 11.2±1,9.3±2,and 4.9±1.3 mm/a while their vertical slip rates are 1.2±0.2,0.7±0.1,and 0.3 mm/a in the late Quaternary.Results indicate that the slip rates regularly decrease along the eastern ~300 km of the fault from >10 to <5 mm/a.This is consistent with the decrease in the gradient such that at the slip rate break point is at the triple point intersection with the transverse fault,which in turn is transformed to the Awancang Fault.The vector decomposition for this tectonic transformation shows that the western and eastern branches of the Awancang Fault fit the slip-partitioning mode.The slip rate of the southwestern wall is 4.6 mm/a relative to the northeastern wall and the slip direction is 112.1°.The mid-eastern part of the Kunlun Fault can be divided into three independent segments by the A'nyêmaqên double restraining bend and the Xigongzhou intersection zone,which compose the surface rupture segmentation indicators for themselves as well as the ending point of the 1937 M7.5 Tuosuohu earthquake.The average recurrence interval of the characteristic earthquakes are estimated to be 500-1000 a,respectively.The latest earthquake ruptures occurred in AD 1937 on the western Tuosuohu segment,as compared to ~514-534 a BP on the Maqin segment,and ~1055 to 1524 a BP on the Maqu segment.This may indicate a unidirectional migration for surface rupturing earthquakes along the mid-eastern Kunlun Fault related to stress triggered between these segments.Meanwhile,the long-term slip rate is obtained through the single event offset and the recurrence interval,which turn out to be the same results as those determined by the offset tectonic geomorphology method,i.e.,the decreasing gradient corresponds to the geometrical bending and the fault's intersection with the transverse fault.Therefore,the falling slip rate gradient of the mid-eastern Kunlun Fault is mainly caused by eastward extension of the fault and its intersection with the transverse fault. | LI ChenXia XU XiWei WEN XueZe ZHENG RongZhang CHEN GuiHua YANG Hu AN YanFen GAO Xiang | 2011 | Science China Earth Sciences2011，54，11： | 33 |

| 4 | Deep seismic reflection profile across the juncture zone between the Tarim Basin and the West Kunlun Mountains显示文摘Fine structures of the crust and upper mantle of the basin-and-range juncture on the northwestern margin of the Qinghai-Tibetan Plateau are first delineated by the deep seismic reflection profile across the juncture zone between the Tarim Basin and the West Kunlun Mountains. Evidence is found for the northward subduction of the northwest marginal lithosphere of the Qinghai-Tibetan Plateau and its collision with Tarim lithosphere beneath the West Kunlun Mountains. The lithosphere image of the face-to-face subduction and collision determines the coupling relationship between the Tarim Basin and the West Kunlun Mountains at the lithosphere scale and reflects the process of continent- continent collision. | GAO Rui HUANG Dongding LU Deyuan QIAN Guihua LI Yingkang KUANG Chaoyang Li Qiusheng LI Pengwu Feng Rujin Guan Ye | 2000 | Chinese Science Bulletin2000，45，24： | 30 |
| 5 | Effect of scraping therapy on Interleukin-1 in serum of rats with lumbar disc herniation显示文摘OBJECTIVE:To explore the effect of scraping therapy on the Interleukin-1 (IL-1) levels of rats with lumbar disc herniation (LDH). METHODS: Fifty male rats were devided into a blank group (A), a sham operation group (B), a model group (C), a scraping group (D), and a drug group (E). The rats in the group B were treated with sham operation, and groups C, D and E were made into the LDH model by operation. After operation group C were treated with no interventions, D were given scraping and E were fed with azathioprine Then the IL-1 levels of different groups were detected by enzyme-linked immuno sorbent assay method. And the transplanted coccygeal vertebra discs were observed by pathological section. RESULTS: The IL-1 levels in the groups C, D, and E were significantly higher than those in the groups A and B (all P<0.01), which proved the operationwas successful.The IL-1 levels in the groups D and E at different periods had statistical significance (F= 414.158, P<0.01). The treatment periods and interventions have interation (F=46.613, P<0.01). Multiple comparison results showed that the IL-1 levels in the groups D and E was significantly lower than that in the group C (P<0.01), while the IL-1 levels between the groups D and E had no statistical significance (P>0.05). Moreover, pathological section indicated that immuno-inflammatory response was hardly found in coccygeal vertebra discs in the groups A and B, while local immuno-inflammatory responses of the groups D and E were much lighter than that of the group C. CONCLUSION: Scraping therapy could inhibit the immuno-inflammatory responses in the rats with LDH caused by transplantation of autologous nu cleus pulposus. | Rongrong Jiang Guihua Xu Hua Chen Jie Li Tao Yang Yang Guo | 2013 | Journal of Traditional Chinese Medicine2013，33，1： | 23 |
| 6 | Annual cost of illness of stomach and esophageal cancer patientsin urban and rural areas in China: A multi-center study显示文摘Objective: Stomach and esophageal cancer are imposing huge threats to the health of Chinese people whereas there were few studies on the financial burden of the two cancers.Methods: Costs per hospitalization of all patients with stomach or esophageal cancer discharged between September 2015 and August 2016 in seven cities/counties in China were collected, together with their demographic information and clinical details. Former patients in the same hospitals were sampled to collect information on annual direct non-medical cost, indirect costs and annual number of hospitalization. Annual direct medical cost was obtained by multiplying cost per hospitalization by annual number of hospitalization. Annual cost of illness(ACI)was obtained by adding the average value of annual direct medical cost, direct non-medical cost and indirect cost,stratified by sex, age, clinical stage, therapy and pathologic type in urban and rural areas. Costs per hospitalization were itemized into eight parts to calculate the proportion of each part. All costs were converted to 2016 US dollars(1 USD=6.6423 RMB).Results: Totally 19,986 cases were included, predominately male. Mean ages of stomach cancer and urban patients were lower than that of esophageal cancer and rural patients. ACI of stomach and esophageal cancer patients were $10,449 and $13,029 in urban areas, and $2,927 and $3,504 in rural areas, respectively. Greater ACI was associated with male, non-elderly patients as well as those who were in stage I and underwent surgeries.Western medicine fee took the largest proportion of cost per hospitalization.Conclusions: The ACI of stomach and esophageal cancer was tremendous and varied substantially among the population in China. Preferential policies of medical insurance should be designed to tackle with this burden and further reduce the health care inequalities. | Zhixun Yang Hongmei Zeng Ruyi Xia Qian Liu Kexin Sun Rongshou Zheng Siwei Zhang Changfa Xia He Li Shuzheng Liu Zhiyi Zhang Yuqin Liu Guizhou Guo Guohui Song Yigong Zhu Xianghong Wu Bingbing Song Xianzhen Liao Yanfang Chen Wenqiang Wei Guihua Zhuang Wanqing Chen | 2018 | Chinese Journal of Cancer Research2018，30，4： | 22 |
| 7 | Lattice Boltzmann method and its applications in engineering thermophysics显示文摘The lattice Boltzmann method (LBM), a mesoscopic method between the molecular dynamics method and the conventional numerical methods, has been developed into a very efficient numerical alternative in the past two decades. Unlike conventional numerical methods, the kinetic theory based LBM simulates fluid flows by tracking the evolution of the particle distribution function, and then accumulates the distribution to obtain macroscopic averaged properties. In this article we review some work on LBM applications in engineering thermophysics: (1) brief introduction to the development of the LBM; (2) fundamental theory of LBM including the Boltzmann equation, Maxwell distribution function, Boltzmann-BGK equation, and the lattice Boltzmann-BGK equation; (3) lattice Boltzmann models for compressible flows and non-equilibrium gas flows, bounce back-specular-reflection boundary scheme for microscale gaseous flows, the mass modified outlet boundary scheme for fully developed flows, and an implicit-explicit finite-difference-based LBM; and (4) applications of the LBM to oscillating flow, compressible flow, porous media flow, non-equilibrium flow, and gas resonant oscillating flow. | HE YaLing LI Qing WANG Yong TANG GuiHua | 2009 | Chinese Science Bulletin2009，54，22： | 19 |
| 8 | Colorectal cancer burden and trends:Comparison between China and major burden countries in the world显示文摘Objective:To summarize the colorectal cancer(CRC)burden and trend in the world,and compare the difference of CRC burden between other countries and China.Methods:Incidence and mortality data were extracted from the GLOBOCAN2018 and Cancer Incidence in Five Continents.Age-specific incidence trend was conducted by Joinpoint analysis and average annual percent changes were calculated.Results:About 1.85 million new cases and 0.88 million deaths were expected in 2018 worldwide,including 0.52 million(28.20%)new cases and 0.25 million(28.11%)deaths in China.Hungary had the highest age-standardized incidence and mortality rates in the world,while for China,the incidence and mortality rates were only half of that.CRC incidence and mortality were highly correlated with human development index(HDI).Unlike the rapid increase in Republic of Korea and the downward trend in Canada and Australia,the age-standardized incidence rates by world standard population in China and Norway were rising gradually.The age-specific incidence rate in the age group of 50-59 years in China was increasing rapidly,while in Republic of Korea and Canada,the fastest growing age group was 30-39 years.Conclusions:The variations of CRC burden reflect the difference of risk factors,as well as levels of HDI and screening(early detection activities).The burden of CRC in China is high,and the incidence of CRC continues to increase,which may lead to a sustained increase in the burden of CRC in China in the future.Screening should be expanded to control CRC,and focused on young people in China. | Jiachen Zhou Rongshou Zheng Siwei Zhang Hongmei Zeng Shaoming Wang Ru Chen Kexin Sun Minjuan Li Jianhua Gu Guihua Zhuang Wenqiang Wei | 2021 | Chinese Journal of Cancer Research2021，33，1： | 16 |

| 10 | P wave velocity structure of upper and middle crust beneath the Three Gorges reservoir dam and adjacent regions显示文摘The three-dimensional P wave velocity structures of upper and middle crust beneath the Three Gorges reservoir dam and adjacent regions were reconstructed by means of the seismic tomography, using the absolute P-arrivals from the events observed by the Three Gorges seismic network. Our preliminary study of the deep structure shows: (1) the lithology of the Huangling anticline, integral and highly so-lidified, exhibits a uniformity. Down to a depth of 20 km, the Huangling anticline still shows high- velocity anomalies. Note that the characteristics of the velocity images with the different depths are not the same; (2) the depth of the sedimentary rocks beneath the entire Zigui basin is not constant, which is less than 6 km; (3) the top boundary of the crystalline basement varies from 0 to 7 km, whereas the bottom one between 14 and 16 km; (4) the partially molten substances of the upper mantle are located in the Badong-Zigui and its adjacent regions as well as nearby Peishi area. The development and evo-lution of the current tectonics are associated with the cooling and solidifying process of the molten substances within the upper mantle; (5) the different velocity structures of the deep crust in both east and west side of the Jiuwanxi fault are to be investigated in order to understand the origin of gravita-tional gradient zone in the Three Gorge areas; and (6) the velocities within the upper crust would be affected by reservoir water permeability. | LI Qiang ZHAO Xu CAI JinAn LIU RuiFeng LONG GuiHua AN YanRu | 2009 | Science China Earth Sciences2009，52，4： | 11 |
| 11 | Transcriptional landscape of rice roots at the single-cell resolution显示文摘There are two main types of root systems in flowering plants,namely taproot systems of dicots and fibrous root systems found in monocots.Despite this fundamental split,our current knowledge of cellular and molecular mechanism driving root development is mainly based on studies of the dicot model Arabidopsis.However,the world major crops are monocots and little is known about the transcriptional programs underlying cell-type specification in this clade.Here,we report the transcriptomes of more than 20000 single cells derived from root tips of two agronomically important rice cultivars.Using combined computational and experimental analyses we were able to robustly identify most of the major cell types and define novel cell-type-specific marker genes for both cultivars.Importantly,we found divergent cell types associated with specific regulatory programs,including phytohormone biosynthesis,signaling,and response,which were well conserved between the two rice cultivars.In addition,we detected substantial differences between the cell-type transcript profiles of Arabidopsis and rice.These species-specific features emphasize the importance of analyzing tissues across diverse model species,including rice.Taken together,our study provides insight into the transcriptomic landscape of major cell types of rice root tip at single-cell resolution and opens new avenues to study cell-type specification,function,and evolution in plants. | Qing Liu Zhe Liang Dan Feng Sanjie Jiang Yifan Wang Zhuoying Du Ruoxi Li Guihua Hu Pingxian Zhang Yanfei Ma Jan ULohmann Xiaofeng Gu | 2021 | Molecular Plant2021，14，3： | 9 |
| 12 | Establishment of an efficient transformation protocol and its application in marine-derived Bacillus strain显示文摘Marine-derived Bacillus strains have been proved to be a very promising source for natural product leads.However,transformation of environmental strains is much more difficult than that of domesticated strains.Here,we report the development of an efficient and robust electroporation-based transformation system for marine-derived Bacillus marinus B-9987,which is a macrolactin antibiotics producer and a very promising biological control agent against fungal plant diseases.The transformation efficiency was greatly enhanced 103-fold by using unmethylated plasmid to bypass modification-restriction barrier,and using glycine betaine to protect cells from electrical damages during electroporation.Addition of HEPES and 2 mmol L?1MgCl2 further improved the efficiency by additional 2-fold,with a maximum value of 7.1×104 cfu/μg pHT3101.To demonstrate the feasibility and efficiency of the protocol,a green fluorescent protein reporter system was constructed;furthermore,phosphopantetheinyl transferase gene sfp,which is essential to the biosynthesis of polyketides and nonribosomal peptides,was overexpressed in B-9987,leading to increased production of macrolactin A by about 1.6-fold.In addition,this protocol is also applicable to marine-derived Bacillus licheniforms EI-34-6,indicating it could be a reference for other undomesticated Bacillus strains.To our knowledge,this is the first report regarding the transformation of marine-derived Bacillus strain. | LIU Yang ZHENG Hua ZHAN GuiHua QIN Wen TIAN Li LI WenLi | 2014 | Science China(Life Sciences)2014，57，6： | 9 |
| 13 | High-Resolution Genome-wide Association Study Identifies Genomic Regions and Candidate Genes for Important Agronomic Traits in Wheat显示文摘Wheat(Triticum aestivum)is a major staple food crop worldwide.Genetic dissection of important agronomic traits is essential for continuous improvement of wheat yield to meet the demand of the world's growing population.We conducted a large-scale genome-wide association study(GWAS)using a panel of 768 wheat cultivars that were genotyped with 327609 single-nucleotide polymorphisms generated by genotyping-by-sequencing and detected 395 quantitative trait loci(QTLs)for 12 traits under 7 environments.Among them,273 QTLs were delimited to≤1.0-Mb intervals and 7 of them are either known genes(Rht-D,Vrn-B1,and Vrn-D1)that have been cloned or known QTLs(TaGA2ox8,APO1,TaSus1-7B,and Rht12)that were previously mapped.Eight putative candidate genes were identified for three QTLs that enhance spike seed setting and grain size using gene expression data and were validated in three bi-parental populations.Protein sequence analysis identified 33 putative wheat orthologs that have high identity with rice genes in QTLs affecting similar traits.Large r^2 values for additive effects observed among the QTLs for most traits indicated that the phenotypes of these identified QTLs were highly predictable.Results from this study demonstrated that significantly increasing GWAS population size and marker density greatly improves detection and identification of candidate genes underlying a QTL,solidifying the foundation for large-scale QTL fine mapping,candidate gene validation,and developing functional markers for genomics-based breeding in wheat. | Yunlong Pang Chunxia Liu Danfeng Wang Paul St.Amand Amy Bernardo Wenhui Li Fang He Linzhi Li Liming Wang Xiufang Yuan Lei Dong Yu Su Huirui Zhang Meng Zhao Yunlong Liangi Hongze Jia Xitong Shen Yue Lu Hongming Jiang Yuye Wu Anfei Li Honggang Wang Lingrang Kong Guihua Bai Shubing Liu | 2020 | Molecular Plant2020，13，9： | 8 |
| 14 | Activin A prevents neuron-like PC12 cell apoptosis after oxygen-glucose deprivation显示文摘In this study, PC12 cells were induced to differentiate into neuron-like cells using nerve growth facto and were subjected to oxygen-glucose deprivation. Cells were treated with 0, 10, 20, 30, 50, 100 ng/mL exogenous Activin A. The 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide assay and Hoechst 33324 staining showed that the survival percentage of PC12 cells significantly decreased and the rate of apoptosis significantly increased after oxygen-glucose deprivation. Exogenous Activin A significantly increased the survival percentage of PC12 cells in a dose-dependent manner. Reverse transcription-PCR results revealed a significant increase in Activin receptor IIA, Smad3 and Smad4 mRNA levels, which are key sites in the Activin A/Smads signaling pathway, in neuron-like cells subjected to oxygen-glucose deprivation, while mRNA expression of the apoptosis-regulation gene caspase-3 decreased. Our experimental findings indicate that exogenous Activin A plays an anti-apoptotic role and protects neurons by means of activating the Activin A/Smads signaling pathway. | Guihua Xu Jinting He Hongliang Guo Chunli Mei Jiaoqi Wang Zhongshu Li Han Chen Jing Mang Hong Yang Zhongxin Xu | 2013 | Neural Regeneration Research2013，8，11： | 5 |

| 16 | Liposomes for systematic delivery of vancomycin hydrochloride to decrease nephrotoxicity:Characterization and evaluation显示文摘Vancomycin hydrochloride(VANH),the first glycopeptide antibiotic,is a water-soluble drug for the treatment of acute osteomyelitis.Liposomal formulations of VANH have already been manipulated and characterized,which was a mean of increasing their therapeutic index,reducing their toxicity and altering drug biodistribution.One of the challenges for preparing VANH-Lips is their low encapsulation efficiency(EE).In the present study,we aim to improve the liposomal formulation of VANH for higher EE,longer systemic circulation,reduced nephrotoxicity and enhanced antimicrobial activities.Vancomycin hydrochloride-loaded liposomes(VANH-Lips)were formulated by the method of modified reverse phase evaporation.Based on the optimization of formulation with orthogonal experimental design,the average drug encapsulation efficiency and the mean particle size of VANH-Lips were found to be 40.78±2.56%and 188.4±2.77 nm.In vitro drug release of VANH-Lips possessed a sustained release characteristic and their release behavior was in accordance with the Weibull equation.After intravenous injection to mice,the mean residence time(MRT)of VANH-Lips group was significantly prolonged in vivo and the AUC value was improved as well compared with the vancomycin hydrochloride solution(VANH-Sol)group.Furthermore,the biodistribution results in mice showed that VANH-Lips decreased the accumulation of VANH in kidney after intravenous injection.In conclusion,VANH-Lips may be a potential delivery system for VANH to decrease nephrotoxicity in the treatment of osteomyelitis. | Junli Liu Zhonglan Wang Fubing Li Jinhua Gao Longmei Wang Guihua Huang | 2015 | Asian Journal of Pharmaceutical Sciences2015，10，3： | 4 |
| 17 | Crystallization and Corrosion Resistance of (Fe_(0.78)Si_(0.09)B_(0.13))100_(-x)Ni_x (x=0,2 and 5) Glassy Alloys显示文摘The crystallization of the (Fe0.78Si_(0.09)B0.13)100-xNix glassy alloys (x=0, 2 and 5) has been investigated by X-ray diffraction (XRD) and differential scanning calorimeter (DSC). Corrosion resistance analyses have been carried out using electrochemical measurements and corrosion products have been analyzed by scanning electron microscopy (SEM). The experimental results show that the addition of Ni can promote the nucleation of α-Fe, retard the decomposition of the metastable borides, and alter the crystallization mode of the present Fe-based glassy alloys. The lattice constant (a0Fe) of α-Fe in the annealed samples shows a decreasing trend with increasing annealing time. The Ni addition can improve the corrosion resistance of the as-quenched Fe-based glassy alloys in H2SO4, NaCl and NaOH solutions. The results indicate that Ni can promote the diffusion of Si atoms during quenching and annealing processes. | Haitian Ma Weimin Wang die Zhang Guihua Li Chongde Cao Hongdi Zhang | 2011 | Journal of Materials Science & Technology2011，27，12： | 4 |
| 18 | Restoring environmental flows and improving riparian ecosystem of Tarim River显示文摘Rapid population growth and artificial oasis enlargement did pose great threat to the natural riparian ecosystems of Tarim River and caused seriously ecological deterioration and greater desertification of the Tarim River Basin in the second half of 20 century. Restoration of the endangered riparian ecosystem requires that environmental flow should be restored through restricted and uncontrolled flow diversion irrigation in tributary areas. Implementation of such restriction needs further the basin-wide reallocation of water resources through a set of engineering and non-engineering measures taken to ensure the water requirement in the tributary and maintain effective flows in Tarim River. As one of evolving HELP (Hydrology for Environment, Life and Policy) basins, the article first presents an overview of hydrology, socio-economic development and ecosystem evolution of the Tarim River Basin. Then, those measures for restoring and maintaining environmental flow are reviewed and analyzed along with its applicability and validity. The issues emerging in implementing those measures are also explored, and then the conclusions were summarized. Lessons learned could provide a good example for other basins under similar conditions. | Zhang, JieBin Wu, GuiHua Wang, QiMeng Li, XiaoYan | 2010 | Journal of Arid Land2010，2，1： | 4 |
| 19 | Controllable photodynamic performance via an acidic microenvironment based on two-dimensional metal-organic frameworks for photodynamic therapy显示文摘Photodynamic therapy(PDT)is a widely-used technology for cancer therapy,but conventional photosensitizers still face some drawbacks,such as hydrophobicity,inadequate pharmacokinetics,low cell/tissue specificity,and uncontrollable photodynamic performance during the therapeutic process.Herein,we present a controllable photodynamic performance based on two-dimensional metal-organic frameworks(2D Zn-TCPP MOF)that displayed a week PDT effect under a neutral environment upon exposure to a 660 nm laser due to the degeneracy of Q bands of TCPP.However,the 2D Zn-TCPP MOF showed a significantly enhanced PDT effect in an acidic environment under irradiation with a 660 nm laser due to the released TCPP from decomposed MOF structure.From the in vitro outcomes,the 2D Zn-TCPP MOF showed controllable photodynamic performance from neutral to acidic environments.Due to the acidic tumor microenvironment,the 2D Zn-TCPP MOF presented the strongest antitumor effect in vivo under irradiation with a 660 nm laser.This work offers a promising strategy to develop a next-generation photosensitizer. | Lifeng Hang Tao Zhang Hua Wen Lianbao Liang Wuming Li Xiaofen Ma Guihua Jiang | 2021 | Nano Research2021，14，3： | 4 |
| 20 | Integration of meta-QTL discovery with omics: Towards a molecular breeding platform for improving wheat resistance to Fusarium head blight显示文摘Fusarium head blight(FHB) is a global wheat disease that devastates wheat production. Resistance to FHB spread within a wheat spike(type Ⅱ resistance) and to mycotoxin accumulation in infected kernel(type Ⅲ resistance) are the two main types of resistance. Of hundreds of QTL that have been reported, only a few can be used in wheat breeding because most show minor and/or inconsistent effects in different genetic backgrounds. We describe a new strategy for identifying robust and reliable meta-QTL(mQTL)that can be used for improvement of wheat FHB resistance. It involves integration of mQTL analysis with mQTL physical mapping and identification of single-copy markers and candidate genes. Using metaanalysis, we consolidated 625 original QTL from 113 publications into 118 genetic map-based mQTL(gmQTL). These gmQTL were further located on the Chinese Spring reference sequence map. Finally, 77 high-confidence mQTL(hcmQTL) were selected from the reference sequence-based mQTL(smQTL).Locus-specific single nucleotide polymorphism(SNP) and simple sequence repeat(SSR) markers and17 genes responsive to FHB were then identified in the hcmQTL intervals by combined analysis of transcriptomic and proteomic data. This work may lead to a comprehensive molecular breeding platform for improving wheat resistance to FHB. | Tong Zheng Chen Hua Lei Li Zhengxi Sun Minmin Yuan Guihua Bai Gavin Humphreys Tao Li | 2021 | The Crop Journal2021，9，4： | 4 |
