| 1 | Genetic diversity and construction of core collection in Chinese wheat genetic resources显示文摘Genetic diversity among 5029 accessions representing a proposed Chinese wheat core collection was analyzed using 78 pairs of fluorescent microsatellite (SSR) primers mapped to 21 chromosomes. A stepwise hierarchical sampling strategy with priority based on 4×105 SSR data-points was used to construct a core collection from the 23090 initial collections. The core collection consisted of 1160 accessions, including 762 landraces, 348 modern varieties and 50 introduced varieties. The core ac-counts for 23.1% of the 5029 candidate core accessions and 5% of the 23090 initial collections, but retains 94.9% of alleles from the candidate collections and captures 91.5% of the genetic variation in the initial collections. These data indicate that it is possible to maintain genetic diversity in a core collection while retaining fewer accessions than the accepted standard, i.e., 10% of the initial collections captured more than 70% of their genetic diversity. Estimated genetic representation of the core con-structed by preferred sampling (91.5%) is much higher than that by random sampling (79.8%). Both mean genetic richness and genetic diversity indices of the landraces were higher than those of the modern varieties in the core. Structure and principal coordinate analysis revealed that the landraces and the modern varieties were two relatively independent subpopulations. Strong genetic differentiation associated with ecological environments has occurred in the landraces, but was relatively weak in the modern cultivars. In addition, a mini-core collection was constructed, which consisted of 231 accessions with an estimated 70% representation of the genetic variation from the initial collections. The mini-core has been distributed to various research and breeding institutes for detailed phenotyping and breeding of genetic introgression lines. | HAO ChenYang DONG YuChen WANG LanFen YOU GuangXia ZHANG HongNa GE HongMei JIA JiZeng ZHANG XueYong | 2008 | Chinese Science Bulletin2008,53,10: | 27 |
| 2 | A promising new class of irradiation tolerant materials:Ti_2ZrHfV_(0.5)Mo_(0.2) high-entropy alloy显示文摘Recently, high-entropy alloys(HEAs) or multi-principal-element alloys with unprecedented physical,chemical, and mechanical properties, have been considered as candidate materials used in advanced reactors due to their promising irradiation resistant behavior. Here, we report a new single-phase bodycentered cubic(BCC) structured Ti_2 ZrHfV_(0.5)Mo_(0.2) HEA possessing excellent irradiation resistance, i.e.,scarcely irradiation hardening and abnormal lattice constant reduction after helium-ion irradiation,which is completely different from conventional alloys. This is the first time to report the abnormal XRD phenomenon of metallic alloys and almost no hardening after irradiation. These excellent properties make it to be a potential candidate material used as core components in next-generation nuclear reactors. The particular irradiation tolerance derives from high density lattice vacancies/defects. | Yiping Lu Hefei Huang Xuzhou Gao Cuilan Ren Jie Gao Huanzhi Zhang Shijian Zheng Qianqian Jin Yonghao Zhao Chenyang Lu Tongmin Wang Tingju Li | 2019 | Journal of Materials Science & Technology2019,35,3: | 23 |
| 3 | Genetic diversity in Chinese modern wheat varieties revealed by microsatellite markers显示文摘Genetic diversity of 1680 modern varieties in Chinese candidate core collections was analyzed at 78 SSR loci by fluorescence detection system. A total of 1336 alleles were detected, of which 1253 alleles could be annotated into 71 loci. For these 71 loci, the alleles ranged from 4 to 44 with an average of 17.6, and the PIC values changed from 0.19 to 0.89 with an average of 0.69. (1) In the three genomes of wheat, the average genetic richness was B>A>D, and the genetic diversity indexes were B>D>A. (2) Among the seven homoeologous groups, the average genetic richness was 2=7>3>4>6>5>1, and the genetic diversity indexes were 7>3>2>4>6>5>1. As a whole, group 7 possessed the highest genetic diversity, while groups 1 and 5 were the lowest. (3) In the 21 wheat chromosomes, 7A, 3B and 2D possessed much higher genetic diversity, while 2A, 1B, 4D, 5D and 1D were the lowest. (4) The highest average genetic diversity index existed in varieties bred in the 1950s, and then it declined continually. However, the change tendency of genetic diversity among decades was not greatly sharp. This was further illustrated by changes of the average genetic distance between varieties. In the 1950s it was the largest (0.731). Since the 1960s, it has decreased gradually (0.711, 0.706, 0.696, 0.695). The genetic base of modern varieties is becoming narrower and narrower. This should be given enough attention by breeders and policy makers. | HAO Chenyang, WANG Lanfen, ZHANG Xueyong, YOU Guangxia, DONG Yushen, JIA Jizeng, LIU Xu, SHANG Xunwu, LIU Sancai & CAO Yongsheng Key Laboratory of Crop Germplasm & Biotechnology, MOA, Institute of Crop Sciences, Chinese Academy of Agricultural Sciences, Beijing 100081, China Agronomy College, Gansu Agricultural University, Lanzhou 730070, China | 2006 | Science China(Life Sciences)2006,49,3: | 19 |

| 5 | Multi-scale design and optimization for solid-lattice hybrid structures and their application to aerospace vehicle components显示文摘By integrating topology optimization and lattice-based optimization,a novel multi-scale design method is proposed to create solid-lattice hybrid structures and thus to improve the mechanical performance as well as reduce the structural weight.To achieve this purpose,a two-step procedure is developed to design and optimize the innovative structures.Initially,the classical topology optimization is utilized to find the optimal material layout and primary load carrying paths.Afterwards,the solid-lattice hybrid structures are reconstructed using the finite element mesh based modeling method.And lattice-based optimization is performed to obtain the optimal crosssection area of the lattice structures.Finally,two typical aerospace structures are optimized to demonstrate the effectiveness of the proposed optimization framework.The numerical results are quite encouraging since the solid-lattice hybrid structures obtained by the presented approach show remarkably improved performance when compared with traditional designs. | Chuang WANG Jihong ZHU Manqiao WU Jie HOU Han ZHOU Lu MENG Chenyang LI Weihong ZHANG | 2021 | Chinese Journal of Aeronautics2021,34,5: | 14 |
| 6 | Generation of a Hutchinson-Gilford progeria syndrome monkey model by base editing显示文摘Many human genetic diseases,including Hutchinson-Gilford progeria syndrome(HGPS),are caused by single point mutations.HGPS is a rare disorder that causes premature aging and is usually caused by a de novo point mutation in the LMNA gene.Base editors(BEs)composed of a cytidine deaminase fused to CRISPR/Cas9 nickase are highly efficient at inducing C to T base conversions in a programmable manner and can be used to generate animal disease models with single amino-acid substitutions.Here,we generated the first HGPS monkey model by delivering a BE mRNA and guide RNA(gRNA)targeting the LMNA gene via microinjection into monkey zygotes.Five out of six newborn monkeys carried the mutation specifically at the target site.HGPS monkeys expressed the toxic form of lamin A,progerin,and recapitulated the typical HGPS phenotypes including growth retardation,bone alterations,and vascular abnormalities.Thus,this monkey model genetically and clinically mimics HGPS in humans,demonstrating that the BE system can efficiently and accurately generate patient-specific disease models in non-human primates. | Fang Wang Weiqi Zhang Qiaoyan Yang Yu Kang Yanling Fan Jingkuan Wei Zunpeng Liu Shaoxing Dai Hao Li Zifan Li Lizhu Xu Chu Chu Jing Qu Chenyang Si Weizhi Ji Guang-Hui Liu Chengzu Long Yuyu Niu | 2020 | Protein & Cell2020,11,11: | 11 |
| 7 | Resequencing of 145 Landmark Cultivars Reveals Asymmetric Sub-genome Selection and Strong Founder Genotype Effects on Wheat Breeding in China显示文摘Controlled pedigrees and the multi-decade timescale of national crop plant breeding programs offer a unique experimental context for examining how selection affects plant genomes.More than 3000 wheat cultivars have been registered,released,and documented since 1949 in China.In this study,a set of 145 elite cultivars selected from historical points of wheat breeding in China were re-sequenced.A total of 43.75 Tb of sequence data were generated with an average read depth of 17.94x for each cultivar,and more than 60.92 million SNPs and 2.54 million InDels were captured,based on the Chinese Spring RefSeq genome v1.0.Seventy years of breeder-driven selection led to dramatic changes in grain yield and related phenotypes,with distinct genomic regions and phenotypes tar-geted by different breeders across the decades.There are very clear instances illustrating how introduced Italian and otherforeign germplasm was integrated into Chinese wheat programs and reshaped the genomic landscape of local modern cultivars.Importantly,the resequencing data also highlighted significant asymmetric breeding selec-tion among the three sub-genomes:this was evident in both the collinear blocks for homeologous chromosomes and among sets of three homeologous genes.Accumulation of more newly assembled genes in newer cultivars implied the potential value of these genes in breeding.Conserved and extended sharing of linkage disequilibrium(LD)blocks was highlighted among pedigree-related cultivars,in which fewer haplotype differences were detected.Fixation or replacement of haplotypes from founder genotypes after generations of breeding was related to their breeding value.Based on the haplotype frequency changes in LD blocks of pedigree-related cultivars,we propose a strategy for evaluating the breeding value of any given line on the basis of the accumulation(pyramiding)of bene-ficial haplotypes.Collectively,our study demonstrates the influence of 'founder genotypes' on the output of breeding efforts over many decades and also suggests that founder genotype perspectives are in fact more dy-namic when applied in the context of modern genomics-informed breeding. | Chenyang Hao Chengzhi Jiao Jian Hou Tian Li Hongxia Liu Yuquan Wang Jun Zheng Hong Liu Zhihong Bi Fengfeng Xu Jing Zhao Lin Ma Yamei Wang Uzma Majeed Xu Liu Rudi Appels Marco Maccaferri Roberto Tuberosa Hongfeng Lu Xueyong Zhang | 2020 | Molecular Plant2020,13,12: | 9 |
| 8 | Total phenolic, flavonoid content, and antioxidant activity of flour, noodles, and steamed bread made from different colored wheat grains by three milling methods显示文摘The objective of this study was to evaluate the effects of wheat variety, food processing, and milling method on antioxidant properties. Black wheat variety Heibaoshi 1 had the highest total phenolic content(659.8 μg gallic acid equivalents g-1), total flavonoid content(319.3 μg rutin equivalents g-1), and antioxidant activity, whereas light purple wheat variety Shandongzimai 1 had the lowest total flavonoid content(236.2 μg rutin equivalents g-1) and antioxidant activity. Whole wheat flour and partially debranned grain flour had significantly higher total phenolic contents, total flavonoid contents, and antioxidant activity than refined flour(P < 0.05). Compared with flour, total phenolic contents, total flavonoid contents and antioxidant activity decreased in noodles and steamed bread, whereas noodles had slightly higher total phenolic and flavonoid content than steamed bread. Antioxidant activities(by ferric reducing ability of plasma assay) of steamed bread made from whole wheat flour, partially debranned grain flour, and refined flour were 23.5%, 21.1%, and 31.6% lower, respectively, than the corresponding values of flour. These results suggested that black whole wheat flour and partially debranned grain flour are beneficial to human health. | Yaoguang Li Dongyun Ma Dexiang Sun Chenyang Wang Jian Zhang Yingxin Xie Tiancai Guo | 2015 | The Crop Journal2015,3,4: | 7 |

| 10 | Dynamic impact experiment and response characteristics analysis for 1:2 reduced-scale model of hydraulic support显示文摘It is significant to research the impact resistance properties of hydraulic support due to its key support role in the fully mechanized mining face.However,it is difficult for the entire hydraulic support to implement the impact experiment underground and analyze the response characteristic.Therefore,a dynamic impact experiment for the entire hydraulic support was proposed in this paper,where a 1:2 reducedscale model of hydraulic support was designed and its response characteristics under dynamic impact load were analyzed.Firstly,a comprehensive monitoring scheme was proposed to achieve an effective monitoring for dynamic response of hydraulic support.Secondly,a multi-scale impact experiment was carried out for the entire hydraulic support and dynamic behaviors of hydraulic support under the multi-scale impact load were revealed by experimental data.Then a dynamic impact experiment of the entire hydraulic support was simulated in ADAMS with the same experiment conditions,and the experimental and simulation data were verified mutually.Finally,the characteristics of energy conversion and dissipation of the entire experiment system after impact were analyzed.The experiment results showed that the impact resistance properties of hydraulic support largely depended on the initial support conditions and different vertical rigidities affected energy distribution proportion of the entire support system. | Huaiwei Ren Desheng Zhang Shixin Gong Kai Zhou Chenyang Xi Ming He Tijian Li | 2021 | International Journal of Mining Science and Technology2021,31,3: | 5 |
| 11 | A haplotype block associated with thousand-kernel weight on chromosome 5DS in common wheat(Triticum aestivum L.)显示文摘Spike number per unit area, number of grains per spike, and thousand-kernel weight(TKW) are important yield components for wheat(Triticum aestivum L.). TKW has the highest heritability among the three components. We validated 27 simple sequence repeat(SSR) loci associated with TKW in an F2:5breeding population grown in four environments. A cfd78265 bpmarker on chromosome 5DS showed the strongest association with TKW and had a significantly positive effect on TKW compared to allele cfd78259 bp, with mean increases of 5.17, 3.63, 4.11, and 5.16 g in the four environments. Markers cfd67 and cfd40 flanking cfd78 also showed significantly positive associations with TKW with increases of 5.11, 3.29, 4.31, and 4.50 g for cfd67205, and4.98, 3.49, 4.06, and 4.84 g for cfd40187 compared with cfd67203 and cfd40190in the four environments, respectively. A major quantitative trait locus for TKW spanning 2.94 c M on chromosome 5DS was detected by association mapping.Strong linkage disequilibrium(LD)(r2> 0.2) was detected Resear among the three linked markers, which formed three haplotype blocks in the F2:5breeding population. Mean TKW differences between Hap B-I and Hap B-II were 5.80, 4.41, 4.02,and 5.06 g in the four environments, respectively. Moreover,significant LD was detected only between cfd78 and cfd67 and between cfd67 and cfd40 in a germplasm collection. This study provides a base for cloning genes related to TKW on chromosome 5DS. | Yuquan Wang Chenyang Hao Jun Zheng Hongmei Ge Yang Zhou Zhengqiang Ma Xueyong Zhang | 2015 | Journal of Integrative Plant Biology2015,57,8: | 5 |
| 12 | Wheat breeding history reveals synergistic selection of pleiotropic genomic sites for plant architecture and grain yield显示文摘Diversity surveys of crop germplasm are important for gaining insights into the genomic basis for plant architecture and grain yield improvement,which is still poorly understood in wheat.In this study,we exome sequenced 287 wheat accessions that were collected in the past 100 years.Population genetics analysis identified that 6.7%of the wheat genome falls within the selective sweeps between landraces and cultivars,which harbors the genes known for yield improvement.These regions were asymmetrically distributed on the A and B subgenomes with regulatory genes being favorably selected.Genome-wide association study(GWAS)identified genomic loci associated with traits for yield potential,and two underlying genes,TaARF12 encoding an auxin response factor and TaDEP1 encoding the G-proteinγ-subunit,were located and characterized to pleiotropically regulate both plant height and grain weight.Elite single-nucleotide haplotypes with increased allele frequency in cultivars relative to the landraces were identified and found to have accumulated over the course of breeding.Interestingly,we found that TaARF12 and TaDEP1 function in epistasis with the classical plant height Rht-1 locus,leading to propose a“Green Revolution”-based working model for historical wheat breeding.Collectively,our study identifies selection signatures that fine-tune the gibberellin pathway during modern wheat breeding and provides a wealth of genomic diversity resources for the wheat research community. | Aili Li Chenyang Hao Zhenyu Wang Shuaifeng Geng Meiling Jia Fang Wang Xiang Han Xingchen Kong Lingjie Yin Shu Tao Zhongyin Deng Ruyi Liao Guoliang Sun Ke Wang Xingguo Ye Chengzhi Jiao Hongfeng Lu Yun Zhou Dengcai Liu Xiangdong Fu Xueyong Zhang Long Mao | 2022 | Molecular Plant2022,15,3: | 4 |
| 13 | Oryza sativa FER-LIKE FE DEFICIENCY-INDUCED TRANSCRIPTION FACTOR(OsFIT/OsbHLH156)interacts with OsIRO2 to regulate iron homeostasis显示文摘Iron(Fe)is indispensable for the growth and development of plants.It is well known that FER-LIKE FE DEFICIENCY-INDUCED TRANSCRIPTION FACTOR(FIT)is a key regulator of Fe uptake in Arabidopsis.Here,we identify the Oryza sativa FIT(also known as Osb HLH156)as the interacting partner of IRON-RELATED BHLH TRANSCRIPTION FACTOR 2(OsIRO2)that is critical for regulating Fe uptake.The OsIRO2 protein is localized in the cytoplasm and nucleus,but OsFIT facilitates the accumulation of OsIRO2 in the nucleus.Loss-of-function mutations of OsFIT result in decreased Fe accumulation,severe Fe-deficiency symptoms,and disrupted expression of Feuptake genes.In contrast,OsFIT overexpression promotes Fe accumulation and the expression of Fe-uptake genes.Genetic analyses indicate that OsFIT and OsIRO2 function in the same genetic node.Further analyses suggest that OsFIT and OsIRO2 form a functional transcription activation complex to initiate the expression of Fe-uptake genes.Our findings provide a mechanism understanding of how rice maintains Fe homeostasis. | Gang Liang Huimin Zhang Yang Li Mengna Pu Yujie Yang Chenyang Li Chengkai Lu Peng Xu Diqiu Yu | 2020 | Journal of Integrative Plant Biology2020,62,5: | 4 |

| 15 | Fast integration and accumulation of beneficial breeding alleles through an AB–NAMIC strategy in wheat显示文摘Wheat(Triticum aestivum)is among the most important staple crops for safeguarding the food security of the growing world population.To bridge the gap between genebank diversity and breeding programs,we developed an advanced backcross-nested association mapping plus inter-crossed population(AB-NAMIC)by crossing three popular wheat cultivars as recurrent founders to 20 germplasm lines from a mini core collection.Selective backcrossing combined with selection against undesirable traits and extensive crossing within and between sub-populations created new opportunities to detect unknown genes and increase the frequency of beneficial alleles in the AB-NAMIC population.We performed phenotyping of 590 AB-NAMIC lines and a natural panel of 476 cultivars for six consecutive growing seasons and genotyped these 1066 lines with a 660K SNP array.Genome-wide association studies of both panels for plant development and yield traits demonstrated improved power to detect rare alleles and loci with medium genetic effects in AB-NAMIC.Notably,genome-wide association studies in AB-NAMIC detected the candidate gene TaSWEET6-7B(TraesCS7B03G1216700),which has high homology to the rice SWEET6b gene and exerts strong effects on adaptation and yield traits.The commercial release of two derived AB-NAMIC lines attests to its direct applicability in wheat improvement.Valuable information on genome-wide association studymapping,candidate genes,and their haplotypes for breeding traits are available through WheatGAB.Our research provides an excellent framework for fast-tracking exploration and accumulation of beneficial alleles stored in genebanks. | Chengzhi Jiao Chenyang Hao Tian Li Abhishek Bohra Lanfen Wang Jian Hou Hongxia Liu Hong Liu Jing Zhao Yamei Wang Yunchuan Liu Zhiwei Wang Xin Jing Xiue Wang Rajeev K.Varshney Junjie Fu Xueyong Zhang | 2023 | Plant Communications2023,4,3: | 3 |
| 16 | Conversion of the high-yield salinomycin producer Streptomyces albus BK3-25 into a surrogate host for polyketide production显示文摘An ideal surrogate host for heterologous production of various natural products is expected to have efficient nutrient utilization,fast growth,abundant precursors and energy supply,and a pronounced gene expression.Streptomyces albus BK3-25 is a high-yield industrial strain producing type-Ⅰ polyketide sahnomycin,with a unique ability of bean oil utilization.Its potential of being a surrogate host for heterologous production of PKS was engineered and evaluated herein.Firstly,introduction of a three-gene cassette for the biosynthesis of ethylmalonyl-CoA resulted in accumulation of ethylmalonyl-CoA precursor and sahnomycin,and subsequent deletion of the sahnomycin biosynthetic gene cluster resulted in a host with rich supplies of common polyketide precursors,including malonyl-CoA,methylmalonyl-CoA,and ethylmalonyl-CoA.Secondly,the energy and reducing force were measured,and the improved accumulation of ATP and NADPH was observed in the mutant.Furthermore,the strength of a series of selected endogenous promoters based on microarray data was assessed at different growth phases,and a strong constitutive promoter was identified,providing a useful tool for further engineered gene expression.Finally,the potential of the BK3-25 derived host ZXJ-6 was evaluated with the introduction of the actinorhodin biosynthetic gene cluster from Streptomyces coelicolor,and the heterologous production of actinorhodin was obtained.This work clearly indicated the potential of the high-yield sahnomycin producer as a surrogate host for heterologous production of polyketides,although more genetic manipulation should be conducted to streamline its performance. | Xiaojie Zhang Chenyang Lu Linquan Bai | 2017 | Science China(Life Sciences)2017,60,9: | 3 |
| 17 | Tailoring the Meso-Structure of Gold Nanoparticles in Keratin-Based Activated Carbon Toward High-Performance Flexible Sensor显示文摘Flexible biosensors with high accuracy and reliable operation in detecting pH and uric acid levels in body fluids are fabricated using well-engineered metaldoped porous carbon as electrode material.The gold nanoparticles@N-doped carbon in situ are prepared using wool keratin as both a novel carbon precursor and a stabilizer.The conducting electrode material is fabricated at 500℃ under customized parameters,which mimics A-B type(two different repeating units) polymeric material and displays excellent deprotonation performance(pH sensitivity).The obtained pH sensor exhibits high pH sensitivity of 57 mV/pH unit and insignificant relative standard deviation of 0.088%.Conversely,the composite carbon material with sp^2 structure prepared at 700℃ is doped with nitrogen and gold nanoparticles,which exhibits good conductivity and electrocatalytic activity for uric acid oxidation.The uric acid sensor has linear response over a range of 1-150 μM and a limit of detection 0.1 μM.These results will provide new avenues where biological material will be the best start,which can be useful to target contradictory applications through molecular engineering at mesoscale. | Aniruddha BPatil Zhaohui Meng Ronghui Wu Liyun Ma Zijie Xu Chenyang Shi Wu Qiu Qiang Liu Yifan Zhang Youhui Lin Naibo Lin Xiang Yang Liu | 2020 | Nano-Micro Letters2020,12,9: | 3 |
| 18 | Crustal Accretion and Reworking within the Khanka Massif: Evidence from Hf Isotopes of Zircons in Phanerozoic Granitoids显示文摘This paper presents a synthesis and analysis of geochronological, geochemical, and zircon Hf isotopic data of Phanerozoic granitoids within the Khanka massif, with the aim of revealing the accretion and reworking processes of continental crust within the massif. Zircon U-Pb dating indicates that Phanerozoic granitic magmatism within the Khanka massif can be subdivided into eight stages: Late Cambrian, Middle–Late Ordovician, Middle Silurian, Late Carboniferous, Early Permian, Middle–Late Permian to Early Triassic, Late Triassic–Early Jurassic, and Early Cretaceous. The zircon Hf isotopic compositions reveal that crustal accretionary events took place mainly in the Mesoproterozoic and Neoproterozoic. Through time, the zircon ε_(Hf)(t) values gradually increase, indicating that the Phanerozoic granitic magmas were derived from the melting of progressively less ancient and more juvenile crust. The zircon ε_(Hf)(t) values exhibit a gradual decrease with the increases in latitude, which implies that the amounts of ancient crustal components within the lower continental crust of the Khanka massif increased from south to north. At the same latitude range, the zircon Hf isotopic compositions also display some variations. We conclude, therefore, that significant horizontal and vertical heterogeneities existed in the lower continental crust of the Khanka massif during the Phanerozoic. | Xiaoming Zhang Wenliang Xu Chenyang Sun Ting Xu Feng Wang | 2018 | Journal of Earth Science2018,29,2: | 3 |
| 19 | Diversity and sub-functionalization of TaGW8 homoeologs hold potential for genetic yield improvement in wheat显示文摘Grain Weight 8(GW8) in rice is a SQUAMOSA Promoter-Binding Protein-Like(SPL) family transcription factor with multiple biological functions. In this study, three GW8 homoeologs were cloned from homoeologous group 7 chromosomes of wheat. Subcellular localization and trans-activation activity assays suggested that Ta GW8 is a transcriptional activator.Ta GW8 genes were preferentially expressed in young spikes and developing grains. Ectopic expressions of Ta GW8 in Arabidopsis and rice resulted in enhanced vegetative growth,earlier flowering and larger seeds. Ta GW8-7 A was the most highly variable of the three homoeologs with four haplotypes(Hap-1/2/3/4). Ta GW8-7 B had two haplotypes(Hap-L/H).Ta GW8-7 A-Hap-2 was associated with high thousand-grain weight(TGW) and large kernel length and showed higher transcriptional levels and binding activity than the other haplotypes. The high frequency of Ta GW8-7 A-Hap-2 in Chinese wheat populations suggested that it had been extensively selected in breeding. This haplotype showed a high potential for exploitation in global wheat breeding because its frequency was low in exotic germplasm. Ta GW8-7 B-Hap-H produced abundant transcripts and was associated with early heading and maturity, less tiller number and high TGW. This haplotype might be suitable for multiple cropping systems due to short wheat season. In this study we identified sub-functionalization among Ta GW8 homoeologs and obtained functional molecular markers that can be used in breeding for high grain yield. | Lin Ma Chenyang Hao Hongxia Liu Jian Hou Tian Li Xueyong Zhang | 2019 | The Crop Journal2019,7,6: | 3 |
| 20 | Magnetically levitated/piezoelectric/triboelectric hybrid generator as a power supply for the temperature sensor显示文摘The combination of new intelligent materials and structure technology is becoming an effective way in energy havesting and self-powered sensing. In this work, we demonstrate a magnetically levitated/piezoelectric/triboelectric hybrid generator, which does not use complex structure and has high steady output performance. It includes three parts: magnetically levitated generator(MLG), piezoelectric generator(PNG), triboelectric nanogenerator(TENG). The peak power of each is 135 μW, 22 mW and3.6 mW, which are obtained at 1 MΩ, 10 kΩ and 1 kΩ, respectively. The hybrid generator can completely light up light-emitting diodes(LEDs) under the vibration frequency of 20 Hz and the vibration amplitude of 10 mm. It also can charge a 470 μF capacitor.On this basis, we have integrated the hybrid generaor as a power supply into a self-powered tempreature sensing system. The combination of three generators can not only broaden the operating range, but also increase the operating length and sensitivity.This work will extend the application of self-powered sensor in automatic production line and promote the development of industrial control technology. | ZHANG ZengXing HE Jian HAN JianQiang XU HongYan MU JiLiang WEN Tao WANG DaWei TIAN ZhuMei CHEN ZeTian XUE ChenYang | 2017 | Science China(Technological Sciences)2017,60,7: | 3 |
