| 1 | Anatomical and chemical characteristics associated with lodging resistance in wheat显示文摘Anatomical and chemical characteristics of stems affect lodging in wheat(Triticum aestivum L.) cultivars. Traits associated with lodging resistance, such as plant height, stem strength, culm wall thickness, pith diameter, and stem diameter, were extensively investigated in earlier studies. However, the solid stem trait was rarely considered. In this study, we measured a range of anatomical and chemical characteristics on solid and hollow stemmed wheat cultivars. Significant correlations were detected between resistance to lodging and several anatomical features, including width of mechanical tissue, weight of low internodes, and width of stem walls. Morphological features that gave the best indication of improved lodging resistance were increased stem width, width of mechanical tissue layer, and stem density. Multiple linear regression analysis showed that 99% of the variation in lodging resistance could be explained by the width of the mechanical tissue layer, suggesting that solid stemmed wheat has several anatomical features for increasing resistance to lodging. In addition, microsatellite markers GWM247 and GWM340 were linked to a single solid stem QTL on chromosome 3BL in a population derived from the cross Xinongshixin(solid stem)/Line 3159(hollow stem). These markers should be valuable in breeding wheat for solid stem. | Eryan Kong Dongcheng Liu Xiaoli Guo Wenlong Yang Jiazhu Sun Xin Li Kehui Zhan Dangqun Cui Jinxing Lin Aimin Zhang | 2013 | The Crop Journal2013，1，1： | 43 |
| 2 | Characterization of the promoter of phosphate transporter TaPHT1.2 differentially expressed in wheat varieties显示文摘TaPHT1.2 is a functional,root predominantly expressed and low phosphate(Pi) inducible high-affinity Pi transporter in wheat,which is more abundant in the roots of P-efficient wheat genotypes(e.g.,Xiaoyan 54) than in P-inefficient genotypes(e.g.,Jing 411) under both Pi-deficient and Pi-sufficient conditions.To characterize TaPHT1.2 further,we genetically mapped a TaPHT1.2 transporter,TaPHT1.2-D1,on the long arm of chromosome 4D using a recombinant inbred line population derived from Xiaoyan 54 and Jing 411,and isolated a 1,302 bp fragment of the TaPHT1.2-D1 promoter(PrTaPHT1.2-D1) from Xiaoyan 54.TaPHT1.2-D1 shows collinearity with OsPHT1.2 that has previously been reported to mediate the translocation of Pi from roots to shoots.PrTaPHT1.2-D contains a number of Pi-starvation responsive elements,including P1BS,WRKY-binding W-box,and helix-loop-helix-binding elements.PrTaPHT1.2-D1 was then used to drive expression of β-glucuronidase(GUS) reporter gene in Arabidopsis through Agrobacterium-mediated transformation.Histochemical analysis of transgenic Arabidopsis plants showed that the reporter gene was specifically induced by Pi-starvation and predominantly expressed in the roots.As there is only one SNP between the TaPHT1.2-D1 promoters of Xiaoyan 54 and Jing 411,and this SNP does not exist within the Pi-starvation responsive elements,the differential expression of TaPHT1.2 in Xiaoyan 54 and Jing 411 may not be caused by this SNP. | Jun Miao Jinghan Sun Dongcheng Liu Bin Li Aimin Zhang Zhensheng Li Yiping Tong | 2009 | Journal of Genetics and Genomics2009，36，8： | 8 |

| 5 | Whole-genome resequencing of the wheat A subgenome progenitor Triticum urartu provides insights into its demographic history and geographic adaptation显示文摘Triticum urartu is the progenitor of the A subgenome in tetraploid and hexaploid wheat.Uncovering the landscape of genetic variations in T.urartu will help us understand the evolutionary and polyploid characteristics of wheat.Here,we investigated the population genomics of T.urartu by genome-wide sequencing of 59 representative accessions collected around the world.A total of 42.2 million highquality single-nucleotide polymorphisms and 3 million insertions and deletions were obtained by mapping reads to the reference genome.The ancient T.urartu population experienced a significant reduction in effective population size(Ne)from3000000 to140000 and subsequently split into eastern Mediterranean coastal and Mesopotamian-Transcaucasian populations during the Younger Dryas period.A map of allelic drift paths displayed splits and mixtures between different geographic groups,and a strong genetic drift towards hexaploid wheat was also observed,indicating that the direct donor of the A subgenome originated from northwestern Syria.Genetic changes were revealed between the eastern Mediterranean coastal and Mesopotamian-Transcaucasian populations in genes orthologous to those regulating plant development and stress responses.A genome-wide association study identified two single-nucleotide polymorphisms in the exonic regions of the SEMI-DWARF 37 ortholog that corresponded to the different T.urartu ecotype groups.Our study provides novel insights into the origin and genetic legacy of the A subgenome in polyploid wheat and contributes a gene repertoire for genomicsenabled improvements in wheat breeding. | Xin Wang Yafei Hu Weiming He Kang Yu Chi Zhang Yiwen Li Wenlong Yang Jiazhu Sun Xin Li Fengya Zheng Shengjun Zhou Lingrang Kong Hongqing Ling Shancen Zhao Dongcheng Liu Aimin Zhang | 2022 | Plant Communications2022，3，5： | 1 |
| 6 | Novel Natural Allelic Variations at the Rht-1 Loci in Wheat显示文摘Plant height is an important agronomic trait.Dramatic increase in wheat yield during the'green revolution'is mainly due to the widespread utilization of the Reduced height(Rht)-1 gene.We analyzed the natural allelic variations of three homoeologous loci Rht-A1,Rht-B1,and Rht-D1 in Chinese wheat(Triticum aestivum L.)micro-core collections and the Rht-B1/D1 genotypes in over 1,500 bred cultivars and germplasms using a modifed EcoTILLING.We identifed six new Rht-A1 allelic variations(Rht-A1b–g),eight new Rht-B1 allelic variations(Rht-B1h–o),and six new Rht-D1 allelic variations(Rht-D1e–j).These allelic variations contain single nucleotide polymorphisms(SNPs)or small insertions and deletions in the coding or uncoding regions,involving two frame-shift mutations and 15 missenses.Of which,Rht-D1e and Rht-D1h resulted in the loss of interactions of GID1-DELLA-GID2,Rht-B1i could increase plant height.We found that the Rht-B1h contains the same SNPs and 197 bp fragment insertion as reported in Rht-B1c.Further detection of Rht-B1h in Tibet wheat germplasms and wheat relatives indicated that Rht-B1c may originate from Rht-B1h.These results suggest rich genetic diversity at the Rht-1 loci and provide new resources for wheat breeding. | Aixia Li Wenlong Yang Xueyuan Lou Dongcheng Liu Jiazhu Sun Xiaoli Guo Jing Wang Yiwen Li Kehui Zhan Hong-Qing Ling Aimin Zhang | 2013 | Journal of Integrative Plant Biology2013，55，11： | 1 |

| 10 | Synthesis and optoelectronic properties of amino-functionalized carbazole-based conjugated polymers显示文摘A series of alcohol soluble amino-functionalized carbazole-based copolymers were synthesized via Suzuki coupling reaction.The pendent amino groups endow them high solubility in polar solvents,as well as efficient electron injection capability from high work-function metals.The relationships between the photophysical and electrochemical properties and the polymer backbone structure were systematically investigated.These alcohol-soluble carbazole-based copolymers were used as cathode interlayers between the high work-function metal Al cathode and P-PPV emissive layer in polymer light-emitting diodes with device structure of ITO/PEDOT:PSS/P-PPV/interlayer/Al.The resulting devices exhibited improved performance due to the better electron injection/transporting ability of the designed copolymers from Al cathode to the light-emitting layer. | LIU ShengJian ZHANG ZhiPeng CHEN DongCheng DUAN ChunHui LU JunMing ZHANG Jie HUANG Fei SU ShiJian CHEN JunWu CAO Yong | 2013 | Science China Chemistry2013，56，8： | 1 |
| 11 | Structural feature and tectonic evolution of Awati-Bachu area in Tarim Basin显示文摘The research area is situated in the western part of Tarim basin,which includes Awati depression and Bachu uplifted block. It underwent three times processes of compression in a large scale and a near term extension since Cambrian. The first compression occurred during Middle Cambrian to Devonian, which formed fault band folds in NW axial direction. They were 'under-water uplift'and distributed all over the research area. The second compression occurred in Late Permian and formed fault band folds and a few fault propagation folds in NS axial direction. They are developed near Tumuxiuke fault belt and the northern research area. The western anticline is bigger than the eastern one in extent and size. The third compression occurred during Palaeogene to Quaternary and formed tumuxiuke fault belt and fault propagation folds in NW direction. They are distributed over the south part of the research area. Tumuxiuke fault belt is a big scale dextral reversed strike-slip fault belt; it transformed or destroyed the fold structure of the research area. A short-term extension occurred during Early Permian. Tarim Basin is in the rift forming stage of craton, and there exist widespread basic volcanic rocks, basic intrusive bodies and dikes. | Zhihong LIU Defeng ZHU Junyi GAO Xiangmei WU Dongcheng LIN Liguo ZHANG | 2008 | Global Geology2008，11，1： | 0 |
| 12 | The 218th amino acid change of Ser to Ala in TaAGPS-7A increases enzyme activity and grain weight in bread wheat显示文摘ADP-glucose pyrophosphorylase(AGPase)influences cereal productivity.There are few reports on the function of cytosolic AGPase small subunit in bread wheat(TaAGPS).In the present study,TaAGPS was preferentially expressed in developing endosperm during grain-filling stages in bread wheat.TaAGPS allelic variations were characterized in 143 wheat accessions by PacBio RS II sequencing.Two haplotypes(TaAGPS-7A-TG and TaAGPS-7A-CT)of TaAGPS-7A were identified and corresponding functional markers were developed,whereas no variants of TaAGPS-7B and TaAGPS-7D were detected.TaAGPS-7A was associated with thousand-kernel weight(TKW)by haplotype–trait association analysis in two populations.Near-isogenic lines(NILs)with TaAGPS-7A-TG showed higher TKW and total kernel starch content than those with TaAGPS-7A-CT,owing to the higher AGPase activity of TaAGPS-7A-TG than TaAGPS-7A-CT both in vitro and in vivo.Overexpression of TaAGPS-7A-TG in bread wheat doubled the transcription levels of TaAGPS and increased AGPase activity by 55.7%,resulting in a 3.0-g higher TKW than in the wild type(WT).Knockdown of TaAGPS led to reduced expression of TaAGPS,AGPase activity,and TKW than in the WT.Thus,owing to the 218th amino acid change of Ser to Ala in TaAGPS-7A,the favorable haplotype TaAGPS-7A-TG showed higher AGPase activity,resulting in higher kernel starch content and grain weight.This finding could be applied to increasing starch content and grain weight in bread wheat. | Xiaoling Ma Xiang Ouyang Dongcheng Liu Aimin Zhang | 2023 | The Crop Journal2023，11，1： | 0 |
| 13 | Epitranscriptomics and epiproteomics in cancer drug resistance:therapeutic implications显示文摘Drug resistance is a major hurdle in cancer treatment and a key cause of poor prognosis.Epitranscriptomics and epiproteomics are crucial in cell proliferation,migration,invasion,and epithelial–mesenchymal transition.In recent years,epitranscriptomic and epiproteomic modification has been investigated on their roles in overcoming drug resistance.In this review article,we summarized the recent progress in overcoming cancer drug resistance in three novel aspects:(i)mRNA modification,which includes alternative splicing,A-to-I modification and mRNA methylation;(ii)noncoding RNAs modification,which involves miRNAs,lncRNAs,and circRNAs;and(iii)posttranslational modification on molecules encompasses drug inactivation/efflux,drug target modifications,DNA damage repair,cell death resistance,EMT,and metastasis.In addition,we discussed the therapeutic implications of targeting some classical chemotherapeutic drugs such as cisplatin,5-fluorouridine,and gefitinib via these modifications.Taken together,this review highlights the importance of epitranscriptomic and epiproteomic modification in cancer drug resistance and provides new insights on potential therapeutic targets to reverse cancer drug resistance. | Huibin Song Dongcheng Liu Shaowei Dong Leli Zeng Zhuoxun Wu Pan Zhao Litu Zhang Zhe-Sheng Chen Chang Zou | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 0 |
| 14 | Identification of KASP markers and putative genes for pre-harvest sprouting resistance in common wheat(Triticum aestivum L.)显示文摘Common wheat(Triticum aestivum L.)is the most important crop in the world and a typical allopolyploid with a large and complex genome.Pre-harvest sprouting(PHS)leads to a significant reduction in grain quality worldwide.PHS is a complex trait with related QTL located on different chromosomes.However,the study of markers and genes related to PHS resistance is limited especially for whitegrained wheat.Four pairs of near isogenic lines(NILs)from a white-grained wheat cross of CharaDM5637B*8 targeting a major QTL for PHS resistance(Qphs.ccsu-3A.1)on wheat chromosme 3AL were genotyped using the 90K SNP Illumina iSelect array.Ten SNPs were identified,with a 75%-100%consistency between genotype and phenotype in the resistant or susceptible isolines.The 10 SNPs were converted to cost-effective kompetitive allele-specific PCR(KASP)markers.Screening of 48 wheat cultivars with different phenotypes of PHS identified four KASP markers with 81.3%-85.4%conformity between genotype and phenotype.Further investigation revealed that the four SNPs(BS00022245_51,Kukri_c49927_151,BS00022884_51 and BS00110550_51)corresponding to the four validated KASP markers are residing in three independent genes(TraesCS3A03G1072800,TraesCS3A03G1072400,TraesCS3A03G1071800)close to each other with a distance of 4.28-4.48 Mb to the targeted QTL.These three annotated genes have potential functions related to PHS resistance.Our study revealed that combined use of NILs and the 90K SNP chip is a powerful approach for developing KASP markers and mining functional genes in wheat.The KASP markers for PHS resistance on chromosome 3AL are useful for high-throughput evaluation and marker-assisted selection,and the three identified genes could lead to a better understanding of the genetic pathways controlling PHS. | Guannan Liu Daniel Mullan Aimin Zhang Hui Liu Dongcheng Liu Guijun Yan | 2023 | The Crop Journal2023，11，2： | 0 |
