| 1 | QTG-Seq Accelerates QTL Fine Mapping through QTL Partitioning and Whole-Genome Sequencing of Bulked Segregant Samples显示文摘Deciphering the genetic mechanisms underlying agronomic traits is of great importance for crop improvement. Most of these traits are controlled by multiple quantitative trait loci (QTLs), and identifying the underlying genes by conventional QTL fine-mapping is time-consuming and labor-intensive. Here, we devised a new method, named quantitative trait gene sequencing (QTG-seq), to accelerate QTL fine-mapping. QTGseq combines QTL partitioning to convert a quantitative trait into a near-qualitative trait, sequencing of bulked segregant pools from a large segregating population, and the use of a robust new algorithm for identifying candidate genes. Using QTG-seq, we fine-mapped a plant-height QTL in maize (Zea mays L.), qPH7, to a 300-kb genomic interval and verified that a gene encoding an NF-YC transcription factor was the functional gene. Functional analysis suggested that qPH7-encoding protein might influence plant height by interacting with a CO-like protein and an AP2 domain-containing protein. Selection footprint ana卜 ysis indicated that qPH7 was subject to strong selection during maize improvement. In summary, QTG-seq provides an efficient method for QTL fine-mapping in the era of “big data'. | Hongwei Zhang Xi Wang Qingchun Pan Pei Li Yunjun Liu Xiaoduo Lu Wanshun Zhong Minqi Li Linqian Han Juan Li Pingxi Wang Dongdong Li Yan Liu Qing Li Fang Yang Yuan-Ming Zhang Guoying Wang Lin Li | 2019 | Molecular Plant2019，12，3： | 13 |

| 4 | New lncRNA annotation reveals extensive functional divergence of the transcriptome in maize显示文摘Long non-coding RNAs(lncRNAs), whose sequences are approximately 200 bp or longer and unlikely to encode proteins, may play an important role in eukaryotic gene regulation. Although the latest maize(Zea mays L.) reference genome provides an essential genomic resource, genome-wide annotations of maize lncRNAs have not been updated. Here, we report on a large transcriptomic dataset collected from 749 RNA sequencing experiments across different tissues and stages of the maize reference inbred B73 line and 60 from its wild relative teosinte. We identified 18,165 high-confidence lncRNAs in maize, of which 6,873 are conserved between maize and teosinte. We uncovered distinct genomic characteristics of conserved lncRNAs,non-conserved lncRNAs, and protein-coding transcripts.Intriguingly, Shannon entropy analysis showed that conserved lncRNAs are likely to be expressed similarly to protein-coding transcripts. Co-expression network analysis revealed significant variation in the degree of co-expression. Furthermore, selection analysis indicated that conserved lncRNAs are more likely than non-conserved lncRNAs to be located in regions subject to recent selection, indicating evolutionary differentiation. Our results provide the latest genomewide annotation and analysis of maize lncRNAs and uncover potential functional divergence between proteincoding, conserved lncRNA, and non-conserved lncRNA genes, demonstrating the high complexity of the maize transcriptome. | Linqian Han Zhenna Mu Zi Luo Qingchun Pan Lin Li | 2019 | Journal of Integrative Plant Biology2019，61，4： | 2 |

| 7 | Evaluation of maize root growth and genome-wide association studies of root traits in response to low nitrogen supply at seedling emergence显示文摘Nitrogen(N) deficiency is one of the main factors limiting maize(Zea mays L.) productivity. Genetic improvement of root traits could improve nitrogen use efficiency. An association panel of 461 maize inbred lines was assayed for root growth at seedling emergence under high-nitrate(HN, 5 mmol L^(-1))and low-nitrate(LN, 0.05 mmol L^(-1)) conditions. Twenty-one root traits and three shoot traits were measured. Under LN conditions, the root-to-shoot ratio, root dry weight, total root length, axial root length,and lateral root length on the primary root were all increased. Under LN conditions, the heritability of the plant traits ranged from 0.43 to 0.82, a range much wider than that of 0.27 to 0.55 observed under HN conditions. The panel was genotyped with 542,796 high-density single-nucleotide polymorphism(SNP) markers. Totally 328 significant SNP markers were identified using either mixed linear model(MLM) or general linear model analysis, with 34 detected by both methods. In the 100-kb intervals flanking these SNP markers, four candidate genes were identified. Under LN conditions, the protoporphyrinogen IX oxidase 2 gene was associated with total root surface area and the DELLA protein-encoding gene was associated with the length of the visible lateral root zone of the primary root. Under HN conditions, a histone deacetylase gene was associated with plant height. Under both LN and HN conditions, the gene encoding MA3 domain-containing protein was associated with the first whorl crown root number. The phenotypic and genetic information from this study may be exploited for genetic improvement of root traits aimed at increasing NUE in maize. | Xichao Sun Wei Ren Peng Wang Fanjun Chen Lixing Yuan Qingchun Pan Guohua Mi | 2021 | The Crop Journal2021，9，4： | 1 |
| 8 | Design of a novel mitochondria targetable turn-on fluorescence probe for hydrogen peroxide and its two-photon bioimaging applications显示文摘Considering that hydrogen peroxide(H2O2)plays significant roles in oxidative stress,the cellular signal transduction and essential biological process regulation,the detection and imaging of H2O2 in living systems undertakes critical responsibility.Herein,we have developed a novel two-photon fluorescence turn on probe,named as Pyp-B for mitochondria H2O2 detection in living systems.Selectivity studies show that probe Pyp-B exhibit highly sensitive response toward H2O2 than other reactive oxygen species(ROS)and reactive nitrogen species(RNS)as well as biologically relevant species.The fluorescence colocalization studies demonstrate that the probe can localize in the mitochondria solely.Furthermore,as a bio-compatibility molecule,the highly selective and sensitive of fluorescence probe Pyp-B have been confirmed by its cell imaging application of H2O2 in living A549 cells and zebrafishes under the physiological conditions. | Kangnan Wang Wen Ma Yuchun Xu Xin Liu Gui Chen Meng Yu Qiling Pan Chaobo Huang Xiaochuan Li Qingchun Mu Yongbing Sun Zhiqiang Yu | 2020 | Chinese Chemical Letters2020，31，12： | 1 |
| 9 | Insight into coupled Ni-Co dual-metal atom catalysts for efficient synergistic electrochemical CO_(2)reduction显示文摘The development of highly active,selective,and stable electrocatalysts can facilitate the effective implementation of electrocatalytic CO_(2)conversion into fuels or chemicals for mitigating the energy crisis and climate problems.Therefore,it is necessary to achieve the goal through reasonable material design based on the actuality of the operational active site at the molecular scale.Inspired by the stimulating synergistic effect of coupled heteronuclear metal atoms,a novel Ni-Co atomic pairs configuration(denoted as NiN_(3)?CoN_(3)-NC)active site was theoretically screened out for improving electrochemical CO_(2)reduction reaction(CO_(2)RR).The structure of NiN_(3)?CoN_(3)-NC was finely regulated by adjusting Zn content in the precursors Zn/Co/Ni-zeolite imidazolate frameworks(Zn/Co/Ni-ZIFs)and pyrolysis temperature.The structural features of NiN_(3)?CoN_(3)-NC were systematically confirmed by aberration-corrected HAADF-STEM coupled with 3D atom-overlapping Gaussian-function fitting mapping,XAFS,and XRD.The results of theoretical calculations reveal that the synergistic effect of Ni-Co atomic pairs can effectively promote the*COOH intermediate formation and thus the overall CO_(2)RR kinetic was improved,and also restrained the competitive hydrogen evolution reaction.Due to the attributes of Ni-Co atomic pairs configuration,the developed NiN_(3)?CoN_(3)-NC with superior catalytic activity,selectivity,and durability,with a high turnover frequency of 2265 h^(-1)at-1.1 V(vs.RHE)and maximum Faradaic efficiency of 97.7%for CO production.This work demonstrates the great potential of DACs as highly efficient catalysts for CO_(2)RR,provides a useful strategy to design heteronuclear DACs,exploits the synergistic effect of multiple metal sites to facilitate complex CO_(2)RR catalytic reactions,and inspires more efforts to develop the potential of DACs in various fields. | Qingchun Zhang Di Liu Yaping Zhang Zhiliang Guo Minpeng Chen Yuyun Chen Bo Jin Yingze Song Hui Pan | 2023 | Journal of Energy Chemistry2023，，12： | 0 |
| 10 | Effectiveness and safety of tripterygium glycosides tablet(雷公藤多苷片)for lupus nephritis:a systematic review and Meta-analysis显示文摘OBJECTIVE:To investigate the effectiveness and safety of tripterygium glycosides(TG)tablet(雷公藤多苷片)for the treatment of Lupus nephritis(LN).METHODS:Several databases were systematically searched including Pub Med,Embase,Cochrane,Wiley,China National Knowledge Infrastructure Database,Sino Med and Wanfang Library till June 20,2020.Revman5.3 was utilized to analyze the data according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement.RESULTS:In total,8 randomized controlled trials involving 583 participants were identified.Meta-analyses showed that,compared with glucocorticoids(GC)alone,the combination with TG tablet provided a statistically significant improvement in total remission(TR)(RR=1.27,95%CI:1.08–1.50,P=0.004),complete remission(CR)(RR=1.61,95%CI:1.05–2.47,P=0.03)and C3 levels(WMD=0.27,95%CI:0.14–0.39,P<0.0001),C4 levels(WMD=0.12,95%CI:0.07–0.17,P<0.00001).No significant differences were seen in TR,CR,proteinuria,serum creatinine,C3 and C4(TR:RR=1.00,95%CI:0.87–1.16,P=0.95;CR:RR=1.10,95%CI:0.78–1.56,P=0.58;proteinuria levels:WMD=-0.06,95%CI:-0.13 to 0.01,P=0.10;serum creatinine levels:WMD=-0.01,95%CI:-7.36 to 7.35,P=1.00;C3 levels:WMD=0.01,95%CI:-0.06 to 0.07,P=0.84;C4 levels:WMD=-0.01,95%CI:-0.03 to 0.01,P=0.49)between azathioprine(AZA)/leflomit(LEF)+GC and TG tablet+GC.Adverse events(hepatic dysfunction,nausea,vomitting)showed no statistical differences between the TG tablet+GC group and the GC group.There were more new onset of irregular menstruation in the TG tablet+GC group than those in the AZA+GC(RR=3.57,95%CI:1.40–9.11,P=0.008)/LEF+GC(RR=6.69,95%CI:2.42-18.46,P=0.0002)group,but leucopenia lower than those in AZA+GC group(RR=0.38,95%CI:0.17-0.85,P=0.02)and alopecia(RR=0.14,95%CI:0.03-0.77,P=0.02)and rash(RR=0.09,95%CI:0.01-0.69,P=0.02)lower than those in LEF+GC group.Conclusions:This review indicates that TG tablet maybe effective in LN treatment.Nevertheless,adverse events cannot be ignored.Large sample,multi-center,highquality clinical studies are needed to verify the exact effects and safety of TG tablet in treatment of LN. | ZHOU Yingyan LIANG Huasheng YAN Jingyao HE Xiaohong PAN Lili LI Xue CHEN Xianghong CHEN Xiumin YANG Aicheng HUANG Qingchun | 2022 | Journal of Traditional Chinese Medicine2022，42，5： | 0 |
| 11 | Effects of scandium and zirconium combination alloying on as-cast microstructure and mechanical properties of Al-4Cu-1.5Mg alloy显示文摘The influences of minor scandium and zirconium combination alloying on the as-cast microstructure and mechanical properties of Al-4Cu-1.5Mg alloy have been experimentally investigated.The experimental results show that when the minor elements of scandium and zirconium are simultaneously added into the Al-4Cu-1.5Mg alloy,the as-cast microstructure of the alloy is effectively modified and the grains of the alloy are greatly refined.The coarse dendrites in the microstructure of the alloy without Sc and Zr additions are refined to the uniform and fine equiaxed grains.As the additions of Sc and Zr are 0.4% and 0.2%,respectively,the tensile strength,yield strength and elongation of the alloy are relatively better,which are 275.0 MPa,176.0 MPa and 8.0% respectively.The tensile strength is increased by 55.3%,and the elongation is nearly raised three times,compared with those of the alloy without Sc and Zr additions. | Xiang Qingchun Zhao Jing Pan Haicheng Hou Lina Li Rongde | 2011 | China Foundry2011，8，1： | 0 |
| 12 | Sn60Pb40 solder powders produced by the planar flow casting atomization process显示文摘Conventional planar flow casting(PFC) is one of rapid solidification processes for the fabrication of microcrystalline or amorphous ribbons.Based on the conventional PFC process,the planar flow casting atomization(PFCA) process has been developed,which is a new rapid solidification process for the production of metal powder directly from alloy melts.A prototype experimental apparatus was designed and manufactured.With the apparatus,Sn60Pb40 alloy solder powders were prepared,and the effects of the main technological parameters on the powder size distribution and morphology were experimentally studied.The experimental investigations indicate that the metal powders produced by the PFCA process can be classified by velocity;and fine spherical tin-lead alloy solder powders can be fabricated by adjusting the technical parameters.The new PFCA process has such features as high productivity and efficiency,low energy consumption,simple operation,short technological process,and large gross yield. | Xiang Qingchun Zhao Jing Pan Haicheng Li Rongde | 2011 | China Foundry2011，8，2： | 0 |
| 13 | QTL mapping and transcriptome analysis identify candidate genes influencing water–nitrogen interaction in maize显示文摘Water and nitrogen fertilization are the key factors limiting maize productivity.The genetic basis of interactions between maize genotype,water,and nitrogen is unclear.A recombinant inbred line(RIL)maize population was evaluated for seven yield and five agronomic traits under four water and nitrogen conditions:water stress and low nitrogen,water stress and high nitrogen,well-watered and low nitrogen,and well-watered and high nitrogen.Respectively eight,six,and six traits varied in response to genotype–water interactions,genotype–nitrogen interactions,and genotype–water–nitrogen interactions.Using a linkage map consisting of 896 single-nucleotide polymorphism markers and multipleenvironmental quantitative-trait locus(QTL)mapping,we identified 31 QTL,including 12 for genotype–water–nitrogen interaction,across the four treatments.A set of 8060 genes were differentially expressed among treatments.Integrating genetic analysis,gene co-expression,and functional annotation revealed two candidate genes controlling genotype–water–nitrogen interactions,affecting both leaf width and grain yield.Genes involved in abscisic acid biosynthesis and bZIP,NAC,and WRKY transcription factors participated in maize response to water and nitrogen conditions.These results represent a step toward understanding the genetic regulatory network of maize that responds to water and nitrogen stress and provide a theoretical basis for the genetic improvement of both water-and nitrogen-use efficiency. | Kunhui He Yakun Zhang Wei Ren Pengyun Chen Jianchao Liu Guohua Mi Fanjun Chen Qingchun Pan | 2023 | The Crop Journal2023，11，6： | 0 |
| 14 | Corrosion Behavior of Oxide Dispersion Strengthened Ferritic Alloys in Liquid Sodium显示文摘Corrosion behavior of four oxide dispersion strengthened(ODS) ferritic alloys exposed in thermal convective liquid sodium loop for 4 000 h was examined.Surface observation results reveal that coral-like surfaces with deposit initially formed on surfaces of all exposed specimens.In tested alloy S2,χ-phase precipitated in specimen center,and a depleted χ- phase zone formed near the specimen surface.There is a transition area between the surface and center.In the other tested alloys,no notable change on microstructure was observed.Grain boundary attack was not found in any of the tested specimens.Tensile test results indicate that sodium corrosion of the four ODS ferritic alloys for 3 000 h had no notable effect on their tensile properties. | Pan Qingchun Shan Bingquan Tian Yun Liu Guangzu | 1998 | Journal of Iron and Steel Research(International)1998，5，1： | 0 |
| 15 | Genetic dissection of N use efficiency using maize inbred lines and testcrosses显示文摘Although the use of heterosis in maize breeding has increased crop productivity,the genetic causes underlying heterosis for nitrogen(N) use efficiency(NUE) have been insufficiently investigated.In this study,five N-response traits and five low-N-tolerance traits were investigated using two inbred line populations(ILs) consisting of recombinant inbred lines(RIL) and advanced backcross(ABL) populations,derived from crossing Ye478 with Wu312.Both populations were crossed with P178 to construct two testcross populations.IL populations,their testcross populations,and the midparent heterosis(MPH)for NUE were investigated.Kernel weight,kernel number,and kernel number per row were sensitive to N level and ILs showed higher N response than did the testcross populations.Based on a highdensity linkage map,138 quantitative trait loci(QTL) were mapped,each explaining 5.6%–38.8% of genetic variation.There were 52,34 and 52 QTL for IL populations,MPH,and testcross populations,respectively.The finding that 7.6% of QTL were common to the ILs and their testcross populations and that 11.7% were common to the MPH and testcross population indicated that heterosis for NUE traits was regulated by non-additive and non-dominant loci.A QTL on chromosome 5 explained 27% of genetic variation in all of the traits and Gln1-3 was identified as a candidate gene for this QTL.Genome-wide prediction of NUE traits in the testcross populations showed 14%–51% accuracy.Our results may be useful for clarifying the genetic basis of heterosis for NUE traits and the candidate gene may be used for genetic improvement of maize NUE. | Xiaoyang Liu Kunhui He Farhan Ali Dongdong Li Hongguang Cai Hongwei Zhang Lixing Yuan Wenxin Liu Guohua Mi Fanjun Chen Qingchun Pan | 2023 | The Crop Journal2023，11，4： | 0 |
