| 1 | Cloning and expression profiles of 15 genes encoding WRKY transcription factor in wheat (Triticum aestivem L.)显示文摘WRKY proteins are involved in various physiological processes,including biotic and abiotic stress responses,hormone responses and development.However,no systematic identification,expression and function analysis of WRKY genes in wheat were reported.In this study,we isolated 15 wheat cDNAs with complete open reading frame(ORF)encoding putative WRKY proteins using in silico cloning.Phylogenetic analysis indicated that the 15 wheat WRKY genes belonged to three major WRKY groups.Expression analysis revealed that most genes expressed drastically in leaf,except TaWRKY10 which expressed in crown intensively.Four genes were strongly up-reg-ulated with the senescence of leaves.Eight genes were responsive to low temperature,high temperature,NaCl or PEG treatment.More-over,dierential expression patterns were also observed between wheat hybrid and its parents,and some genes were more responsive to PEG treatment in the hybrid.These results demonstrated that wheat WRKY genes are involved in leaf senescing and abiotic stresses.And the changed expression of these WRKY genes in hybrid might contribute to the heterosis by improving the stress tolerance in hybrids. | Hualing Wu Zhongfu Ni Yingyin Yao Ganggang Guo Qixin Sun | 2008 | Progress in Natural Science:Materials International2008，18，6： | 34 |
| 2 | A Collinearity-Incorporating Homology Inference Strategy for Connecting Emerging Assemblies in the Triticeae Tribe as a Pilot Practice in the Plant Pangenomic Era显示文摘Plant genome sequencing has dramatically increased,and some species even have multiple high-quality reference versions.Demands for clade-specific homology inference and analysis have increased in the pangenomic era.Here we present a novel method,GeneTribe(http://gffzz6c7fcf032cb94ff5sx6pkuww5o5fn60on.ffgz.tsg.suse.edu.cn/genetribe/),for homology inference among genetically similar genomes that incorporates gene collinearity and shows bet-ter performance than traditional sequence-similarity-based methods in terms of accuracy and scalability.The Triticeae tribe is a typical allopolyploid-rich clade with complex species relationships that includes many important crops,such as wheat,barley,and rye.We built Triticeae-GeneTribe(http://gffzzaeec8df70e7c4b21hx6pkuww5o5fn60on.ffgz.tsg.suse.edu.cn/TGT/),a homology database,by integrating 12 Triticeae genomes and 3 outgroup model genomes and implemented versatile analysis and visualization functions.With macrocollinearity analysis,we were able to construct a refined model illustrating the structural rearrangements of the 4A-5A-7B chromosomes in wheat as two major translocation events.With collinearity analysis at both the macro-and microscale,we illustrated the complex evolutionary history of homologs of the wheat vernalization gene Vm2,which evolved as a combined result of genome translocation,duplication,and polyploidization and gene loss events.Our work provides a useful practice for connecting emerging genome assemblies,with awareness of the extensive polyploidy in plants,and will help researchers efficiently exploit genome sequence re-sources. | Yongming Chen Wanjun Song Xiaoming Xie Zihao Wang Panfeng Guan Huiru Peng Yuannian Jiao Zhongfu Ni Qixin Sun Weilong Guo | 2020 | Molecular Plant2020，13，12： | 14 |
| 3 | Molecular mapping of QTLs for root response to phosphorus deficiency at seedling stage in wheat (Triticum aestivum L.)显示文摘Phosphorus (P) deficiency in the soil is one of the major abiotic stresses that limit plant growth and crop productivity throughout the world. Development of cultivars with improved P-deficiency tolerance is an efficient strategy for sustainable agriculture. Plant roots play an important role in crop growth and development, especially in nutrient uptake and improvement of P-efficiency. Mapping quantitative trait loci (QTLs) for root traits and their response to low P stress at seedling stage will facilitate the development of P-efficient wheat cultivars. In this study, 30 QTLs (LOD>2.0) were mapped for the three root traits, such as root length, root number and root dry matter under different P supply conditions and their response to P-stress. These QTLs were distributed on 14 chromosomes, with each of the 5 QTLs explaining more than 10% phenotype variance. Analyses showed that root traits and their response to P-deficiency were controlled by different QTLs. In addition, alleles with positive effects were separated on both parents, and wheat cultivars with improved P-efficiency could be developed by accumulating these positive effect alleles together. | Li Zhenxing Ni Zhongfu Peng Huiru Liu Zhiyong Nie Xiuling Xu Shengbao Liu Gang Sun Qixin | 2007 | Progress in Natural Science:Materials International2007，17，10： | 8 |
| 4 | Wheat powdery mildew resistance gene Pm64 derived from wild emmer (Triticum turgidum var.dicoccoides) is tightly linked in repulsion with stripe rust resistance gene Yr5显示文摘Stripe rust and powdery mildew are both devastating diseases for durum and common wheat.Pyramiding of genes conferring resistance to one or more diseases in a single cultivar is an important breeding approach to provide broader spectra of resistances in wheat improvement. A new powdery mildew resistance gene originating from wild emmer(Triticum turgidum var.dicoccoides) backcrossed into common wheat(T. aestivum) line WE35 was identified. It conferred an intermediate level of resistance to Blumeria graminis f. sp. tritici isolate E09 at the seedling stage and a high level of resistance at the adult plant stage. Genetic analysis showed that the powdery mildew resistance in WE35 was controlled by a dominant gene designated Pm64. Bulked segregant analysis(BSA) and molecular mapping indicated that Pm64 was located in chromosome bin 2 BL4-0.50–0.89. Polymorphic markers were developed from the corresponding genomic regions of Chinese Spring wheat and wild emmer accession Zavitan to delimit Pm64 to a 0.55 cM genetic interval between markers WGGBH1364 and WGGBH612, corresponding to a 15 Mb genomic region on Chinese Spring and Zavitan 2 BL, respectively. The genetic linkage map of Pm64 is critical for fine mapping and cloning. Pm64 was completely linked in repulsion with stripe rust resistance gene Yr5. Analysis of a larger segregating population might identify a recombinant line with both genes as a valuable resource in breeding for resistance to powdery mildew and stripe rust. | Deyun Zhang Keyu Zhu Lingli Dong Yong Liang Genqiao Li Tilin Fang Guanghao Guo Qiuhong Wu Jingzhong Xie Yongxing Chen Ping Lu Miaomiao Li Huaizhi Zhang Zhenzhong Wang Yan Zhang Qixin Sun Zhiyong Liu | 2019 | The Crop Journal2019，7，6： | 8 |
| 5 | A natural variation in Ribonuclease H-like gene underlies Rht8 to confer“Green Revolution”trait in wheat显示文摘Dear Editor,Introduction of gibberellin(GA)-insensitive Reduced height(Rht)genes,Rht-B1b and Rht-D1b,has resulted in the“Green Revolution”in modern wheat cultivars(Triticum aestivum)that has skyrocketed wheat grain yields worldwide since the 1960s(Peng et al.,1999;Velde et al.,2021).However,Rht-B1b/D1b also reduce coleoptiles,which is undesired in dryland regions where deep planting is essential for seedling establishment(Rebetzke et al.,1999,Rebetzke et al.,2001;Ellis et al.,2004). | Lingling Chai Mingming Xin Chaoqun Dong Zhaoyan Chen Huijie Zhai Junhong Zhuang Xuejiao Cheng Naijiao Wang Jia Geng Xiaobo Wang Ruolin Bian Yingyin Yao Weilong Guo Zhaorong Hu Huiru Peng Guihua Bai Qixin Sun Zhenqi Su Jie Liu Zhongfu Ni | 2022 | Molecular Plant2022，15，3： | 8 |
| 6 | Molecular dissection of plant height QTLs using recombinant inbred lines from hybrids between common wheat (Triticum aestivum L.) and spelt wheat (Triticum spelta L.)显示文摘In wheat, plant height is an important agronomic trait, and a number of quantitative trait loci (QTLs) controlling plant height have been located. In this study, using the conditional and unconditional QTL mapping methods, combined with data from five different growth stages over two years of field trials, the developmental behavior for plant height in wheat was dissected. Nine unconditional QTLs and 8 conditional QTLs were identified, of which 6 were detected by both methods. None of the 11 QTLs was detected at all of the 5 investigated developmental stages, but 7 QTLs were detected at certain stages in both years. Further analysis identified 9 unconditional QTLs at different stages, which could explain the phenotypic variation from 4.81% to 17.35%. It was noteworthy that one major QTL designated QHt-4B-2, which was located on chromosome 4B, was detected on May 18 and 25 in both years, and its genetic contributions to plant height ranged from 13.42% to 16.13%. Moreover, of the 8 conditional QTLs identified, six were detected in both years, in the order of QHt-3B→QHt-4B-1→QHt-4B-2→QHt-4D→QHt-5A and QHt-2B expressed at the same developmental stage. The results indicate that QTL expression during plant height development is selective and in a temporal order. | LIU Gang XU ShengBao NI ZhongFu XIE ChaoJie QIN DanDan LI Jing LU LaHu ZHANG JinPing PENG HuiRu SUN QiXin | 2011 | Chinese Science Bulletin2011，56，18： | 6 |
| 7 | Shaping polyploid wheat for success:Origins,domestication,and the genetic improvement of agronomic traits显示文摘Bread wheat(Triticum aestivum L.,AABBDD,2 n=6 x=42),which accounts for most of the cultivated wheat crop worldwide,is a typical allohexaploid with a genome derived from three diploid wild ancestors.Bread wheat arose and evolved via two sequential allopolyploidization events and was further polished through multiple steps of domestication.Today,cultivated allohexaploid bread wheat has numerous advantageous traits,including adaptive plasticity,favorable yield traits,and extended end-use quality,which have enabled its cultivation well beyond the ranges of its tetraploid and diploid progenitors to become a global staple food crop.In the past decade,rapid advances in wheat genomic research have considerably accelerated our understanding of the bases for the shaping of complex agronomic traits in this polyploid crop.Here,we summarize recent advances in characterizing major genetic factors underlying the origin,evolution,and improvement of polyploid wheats.We end with a brief discussion of the future prospects for the design of gene cloning strategies and modern wheat breeding. | Jie Liu Yingyin Yao Mingming Xin Huiru Peng Zhongfu Ni Qixin Sun | 2022 | Journal of Integrative Plant Biology2022，64，2： | 5 |
| 8 | Genetic improvement of heat tolerance in wheat:Recent progress in understanding the underlying molecular mechanisms显示文摘As a cool season crop, wheat(Triticum aestivum L.) has an optimal daytime growing temperature of 15 ℃ during the reproductive stage. With global climate change, heat stress is becoming an increasingly severe constraint on wheat production. In this review, we summarize recent progress in understanding the molecular mechanisms of heat tolerance in wheat. We firstly describe the impact of heat tolerance on morphology and physiology and its potential effect on agronomic traits. We then review recent discoveries in determining the genetic and molecular factors affecting heat tolerance, including the effects of phytohormone signaling and epigenetic regulation. Finally, we discuss integrative strategies to improve heat tolerance by utilization of existing germplasm including modern cultivars, landraces and related species. | Zhongfu Ni Hongjian Li Yue Zhao Huiru Peng Zhaorong Hu Mingming Xin Qixin Sun | 2018 | The Crop Journal2018，6，1： | 4 |
| 9 | CAPTURE EFFECT OF ELECTRORHEOLOGICAL SUSPENSIONS IN FLOW FIELD显示文摘According to the results of experiments and theoretical analysis,a phenomenon called “capture effect” is put forward,which could be used to describe the particles dynamic behavior of electrorheological (ER) suspensions. Then a “structure-force” mathematical model is established to explain this effect based on electrostatic energy density equation. The analysis results show that the dynamic coupling process of ER suspensions under an external electric filed is the function not only of the electric intensity,but also of the dielectric properties and the structure form. | ZHU Shisha SUN Hongli HUANG Yijian WANG Qixin | 2007 | Chinese Journal of Mechanical Engineering2007，20，2： | 4 |
| 10 | Genomic and genic sequence variation in synthetic hexaploid wheat (AABBDD) as compared to their parental species显示文摘In order to understand the genomic changes during the evolution of hexaploid wheat, two sets of synthetic hexaploid wheat from hybridization between maternal tetraploid wheat (AABB) and paternal diploid goat grass (DD) were used for DNA-AFLP and single strand conformation polymorphism (SSCP) analysis to determine the genomic and genic variation in the synthetic hexaploid wheat. Results indicated that more DNA sequences from paternal diploid species were eliminated in the synthetic hexaploid wheat than from maternal tetraploid wheat, suggesting that genome from parental species of lower ploidity tends to be eliminated preferentially. However, sequence variation detected by SSCP procedure was much lower than those detected by DNA-AFLP, which indicated that much less variation in the genic regions occurred in the synthetic hexaploid wheat, and sequence variations detected by DNA-AFLP could be derived mostly from non-coding regions and repetitive sequences. Our results also indicated that sequence variation in 4 genes can be detected in hybrid F1, which suggested that this type of sequence variation could be resulted from distant hybridization. It was interesting to note that 3 out of the 4 genes were mapped and clustered on the long arm of chromosome 2D, which indicated that variation in genic sequences in synthetic hexaploid wheat might not be a randomized process. | Lihong Nie Zongfu Han Lahu Lu Yingyin Yao Qixin Sun Zhongfu Ni | 2008 | Progress in Natural Science:Materials International2008，18，5： | 4 |
| 11 | Ectopic expression of VRT-A2 underlies the origin of Triticum polonicum and Triticum petropavlovskyi with long outer glumes and grains显示文摘Polish wheat (Triticum polonicum) is a unique tetraploid wheat species characterized by an elongated outer glume. The genetic control of the long-glume trait by a single semi-dominant locus, P1 (from Polish wheat), was established more than 100 years ago, but the underlying causal gene and molecular nature remain elusive. Here, we report the isolation of VRT-A2, encoding an SVP-clade MADS-box transcription factor, as the P1 candidate gene. Genetic evidence suggests that in T. polonicum, a naturally occurring sequence rearrangement in the intron-1 region of VRT-A2 leads to ectopic expression of VRT-A2 in floral organs where the long-glume phenotype appears. Interestingly, we found that the intron-1 region is a key ON/OFF molecular switch for VRT-A2 expression, not only because it recruits transcriptional repressors, but also because it confers intron-mediated transcriptional enhancement. Genotypic analyses using wheat accessions indicated that the P1 locus is likely derived from a single natural mutation in tetraploid wheat, which was subsequently inherited by hexaploid T. petropavlovskyi. Taken together, our findings highlight the promoter-proximal intron variation as a molecular basis for phenotypic differentiation, and thus species formation in Triticum plants. | Jing Liu Zhaoyan Chen Zhihui Wang Zhaoheng Zhang Xiaoming Xie Zihao Wang Lingling Chai Long Song Xuejiao Cheng Man Feng Xiaobo Wang Yanhong Liu Zhaorong Hu Jiewen Xing Zhenqi Su Huiru Peng Mingming Xin Yingyin Yao Weilong Guo Qixin Sun Jie Liu Zhongfu Ni | 2021 | Molecular Plant2021，14，9： | 4 |
| 12 | Cloning and characterization of an up-regulated GA 20-oxidase gene in hybrid maize显示文摘Previous studies revealed that GA content and metabolism are positively correlated with a faster shoot growth rate of hybrid,and recently,genes participating in both GA biosynthesis and GA response pathways were also found to be differentially expressed between wheat hybrid and its parental inbreds. In this study,an up-regulated GA 20-oxidase gene in a maize hybrid,designated ZmGA20,was cloned. ZmGA20 contains an open reading frame (ORF) encoding 391 amino acid residues. BLASTX searches in GenBank revealed that the ZmGA20 is homologous to the sequences of GA20ox proteins from different species,and analysis also indicated that ZmGA20 had typical features of GA 20-oxidase proteins,including a 'LPWKET' sequence. Semi-quantitative RT-PCR analysis showed that ZmGA20 was expressed in different tissues and/or organs. The expression level of ZmGA20 in the hybrid was higher than that in two parents (in roots,leaves,stems and embryo,and ears). The abundance of ZmGA20 transcript was equal to that of the highly expressed parents,which provided molecular evidence for the observed GA content heterosis in maize hybrids. | Jinkun Du Yingyin Yao Zhongfu Ni Qixin Sun | 2009 | Progress in Natural Science:Materials International2009，19，2： | 4 |
| 13 | Transcriptome Comparison of Susceptible and Resistant Wheat in Response to Powdery Mildew Infection显示文摘Powdery mildew(Pm) caused by the infection of Blumeria graminis f.sp.tritici(Bgt) is a worldwide crop disease resulting in significant loss of wheat yield.To profile the genes and pathways responding to the Bgt infection,here,using Affymetrix wheat microarrays,we compared the leaf transcriptomes before and after Bgt inoculation in two wheat genotypes,a Pm-susceptible cultivar Jingdong 8(S) and its near-isogenic line(R) carrying a single Pm resistant gene Pm30.Our analysis showed that the original gene expression status in the S and R genotypes of wheat was almost identical before Bgt inoculation,since only 60 genes exhibited differential expression by P = 0.01 cutoff.However,12 h after Bgt inoculation,3014 and 2800 genes in the S and R genotype,respectively,responded to infection.A wide range of pathways were involved,including cell wall fortification,flavonoid biosynthesis and metabolic processes.Furthermore,for the first time,we show that sense-antisense pair genes might be participants in wheat-powdery mildew interaction.In addition,the results of qRT-PCR analysis on several candidate genes were consistent with the microarray data in their expression patterns.In summary,this study reveals leaf transcriptome changes before and after powdery mildew infection in wheat near-isogenic lines,suggesting that powdery mildew resistance is a highly complex systematic response involving a large amount of gene regulation. | Mingming Xin Xiangfeng Wang Huiru Peng Yingyin Yao Chaojie Xie Yao Han ZhongfuNi Qixin Sun | 2012 | Genomics, Proteomics & Bioinformatics2012，10，2： | 3 |

| 18 | Ectopic Overexpression of Wheat Adenosine Diphosphate-ribosylation Factor,TaARF,Increases Growth Rate in Arabidopsis显示文摘Differential gene expression between hybrids and their parents is considered to be associated with heterosis. However,the physiological functions and possible contribution to heterosis of these differentially expressed genes are unknown.We have isolated one hybrid upregulated gene encoding putative wheat ADP-ribosylation factor, designated TaARF. In thisstudy, real-time quantitative reverse transcription-polymerase chain reaction analysis indicated that the TaARF transcriptwas preferentially expressed in root, node and crown, and the accumulation of TaARF mRNA in hybrid was more than1.5-fold higher than that in two parents. In order to understand possible roles of the putative wheat ARF gene, TaARFwas overexpressed in Arabidopsis, and the transgenic plants were characterized. We show that ectopic overexpression ofTaARF in Arabidopsis leads to increased leaf area, increased growth rate and earlier transition to flowering, suggestingthat TaARF plays significant roles in growth and development. This study provides evidence demonstrating that TaARFplays important roles in gr owth and development and we speculate that the upregulated expression of this gene mightcontribute to the heterosis observed in wheat root and leaf growth. | Yingyin Yao Zhongfu Ni Jinkun Du Zongfu Han Yan Chen Qingbo Zhang Qixin Sun | 2009 | Journal of Integrative Plant Biology2009，51，1： | 2 |
