| 1 | Improvement of wheat drought and salt tolerance by expression of a stress- inducible transcription factorGmDREB of soybean (Glycinemax)显示文摘Under stress conditions such as droughthigh-salinity and low-temperature, the transcription factorof DREB (dehydration responsive element binding proteins)improved efficiently stress resistance by regulating the ex-pression of its downstream genes with various environmentastress resistance in plants. GmDREB gene (GenBank Acces-sion No. AF514908) encoding a stress-inducible transcriptionfactor was cloned by screening a cDNA library of Glycinemax cv. Jinong 27 with yeast one-hybrid method. GmDREBgene was 910 bp in length and encoded 174 amino acids con-taining a conserved AP2/EREBP DNA-binding domain of 58amino acids. Two conserved functional amino acids, valineand glutamic acid, were located on the 14th and the 19thamino acid residues in the conserved structural domain. Analkaline amino acid region (KKR) related to a nuclear local-ization signal was at the N-terminal, while an acidic aminoacid region (DDD) related to trans-activation was at theC-terminal. Plant expression vectors were constructed andtransformed into wheat by bombardment. In total, 13 trans-genic plants with Ubi::GmDREB and 11 transgenic plantswith rd29A::GmDREB were identified from 103 regenerationplants by molecular analysis. The drought and salt tolerancesof T1 transgenic lines with Ubi::GmDREB orrd29A::GmDREB were demonstrated to be improved ascompared to wild type. The result also suggested that bothUbiquitin and rd29A promoters could effectively drive theexpression of the GmDREB gene and enhance drought andsalt tolerance of T1 plants. | GAO Shiqing XU Huijun CHENG Xianguo CHEN Ming XU Zhaoshi LI Liancheng YE Xingguo DU Lipu HAO Xiaoyan MA Youzhi | 2005 | Chinese Science Bulletin2005，50，23： | 30 |
| 2 | Wheat genome editing expedited by efficient transformation techniques:Progress and perspectives显示文摘Genome editing is one of the most promising biotechnologies to improve crop performance.Common wheat is a staple food for mankind. In the past few decades both basic and applied research on common wheat has lagged behind other crop species due to its complex,polyploid genome and difficulties in genetic transformation. Recent breakthroughs in wheat transformation permit a revolution in wheat biotechnology. In this review, we summarize recent progress in wheat genetic transformation and its potential for wheat improvement. We then review recent progress in plant genome editing, which is now readily available in wheat. We also discuss measures to further increase transformation efficiency and potential applications of genome editing in wheat. We propose that, together with a high quality reference genome, the time for efficient genetic engineering and functionality studies in common wheat has arrived. | Ke Wang Bisma Riaz Xingguo Ye | 2018 | The Crop Journal2018，6，1： | 6 |
| 3 | CRISPR/Cas9 editing of wheat TaQ genes alters spike morphogenesis and grain threshability显示文摘The Ta Q alleles as one of the AP2-like transcription factors in common wheat(Triticum aestivum) play an important role in the evolution of spike characteristics from wild and domesticated emmer to modern wheat cultivars. Its loss-of-function mutant not only changed threshability and spike architecture but also affected plant height, flowering time, and floret structure. However, the comprehensive functions of Ta AQ and Ta Dq genes in wheat have not been fully elucidated yet. Here, CRISPR/Sp Cas9 was used to edit wheat Ta AQ and Ta Dq. We obtained homozygous plants in the T1 generation with loss of function of only Ta AQ or Ta Dq and simultaneous loss of function of Ta AQ and Ta Dq to analyze the effect of these genes on wheat spikes and floret shapes. The results demonstrated that the Ta AQ-edited plants and the Ta AQ and Ta Dq simultaneously-edited plants were nearly similar in spike architecture, whereas the Ta Dq-edited plants were different from the wild-type ones only in plant height. Moreover, the Ta AQ-edited plants or the Ta AQ and Ta Dq simultaneously-edited plants were more brittle than the wild-type and the Ta Dqedited plants. Based on the expression profiling, we postulated that the VRN1, FUL2, SEP2, SEP5, and SEP6 genes might affect the number of spikelets and florets per spike in wheat by regulating the expression of Ta Q. Combining the results of this report and previous reports, we conceived a regulatory network of wheat traits, including plant height, spike shape, and floral organs, which were influenced by AP2-like family genes. The results achieved in this study will help us to understand the regulating mechanisms of Ta AQ and Ta Dq alleles on wheat floral organs and inflorescence development. | Huiyun Liu Ke Wang Huali Tang Qiang Gong Lipu Du Xinwu Pei Xingguo Ye | 2020 | Journal of Genetics and Genomics2020，47，9： | 6 |
| 4 | 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 |

| 6 | Dissecting conserved cis-regulatory modules of Glu-1 promoters which confer the highly active endosperm-specific expression via stable wheat transformation显示文摘Wheat high-molecular-weight glutenin subunits(HMW-GS) determine dough elasticity and play an essential role in processing quality. HMW-GS are encoded by Glu-1 genes and controlled primarily at transcriptional level, implemented through the interactions between cis-acting elements and trans-acting factors. However, transcriptional mechanism of Glu-1 genes remains elusive. Here we made a comprehensive analysis of cis-regulatory elements within 1-kb upstream of the Glu-1 start codon(-1000 to-1) and identified 30 conserved motifs. Based on motif distribution pattern, three conserved cis-regulatory modules(CCRMs), CCRM1(-300 to-101), CCRM2(-650 to-400), and CCRM3(-950 to-750), were defined, and their functions were characterized in wheat stable transgenic lines transformed with progressive 5′ deletion promoter::GUS fusion constructs. GUS staining, qP CR and enzyme activity assays indicated that CCRM2 and CCRM3 could enhance the expression level of Glu-1, whereas the 300-bp promoter(-300 to-1), spanning CCRM1 and core region(-100 to-1), was enough to ensure accurate Glu-1 initiation at 7 days after flowering(DAF) and shape its spatiotemporal expression pattern during seed development. Further transgenic assays demonstrated that CCRM1-2(-300 to-209) containing Complete HMW Enhancer(-246 to-209) was important for expression level but had no effect on expression specificity in the endosperm. In contrast, CCRM1-1(-208 to-101) was critical for both expression specificity and level of Glu-1. Our findings not only provide new insights to uncover Glu-1 transcription regulatory machinery but also lay foundations for modifying Glu-1 expression. | Jihu Li Ke Wang Genying Li Yulian Li Yong Zhang Zhiyong Liu Xingguo Ye Xianchun Xia Zhonghu He Shuanghe Cao | 2019 | The Crop Journal2019，7，1： | 2 |
| 7 | Development of powdery mildew resistant derivatives of wheat variety Fielder for use in genetic transformation显示文摘Genetic transformation is widely used to improve target traits and to study gene function in wheat.However,transformation efficiency depends on the physiological status of the recipient genotype and that is affected by several factors including powdery mildew(PM)infection.The widely used recipient variety Fielder is very susceptible to PM.Therefore,it would be beneficial to develop PM resistant derivatives with high regeneration ability for use in genetic transformation.In the present study PM resistant lines CB037 and Pm97033 carrying genes Pm21 and PmV,respectively,were backcrossed to Fielder with selection for PM resistance.Five lines,NT89,NT90,NT154,and WT48 with Pm21 and line FL347 with PmV were developed,identified by molecular markers and genomic in situ hybridization(GISH)or fluorescent in situ hybridization(FISH),and further subjected to detailed assessment of agronomic traits and regeneration ability following genetic transformation capacity.Lines FL347,WT48,NT89 and NT154 assessed as being equal to,or superior,to Fielder in regeneration and transformation ability are recommended as suitable materials for the replacement of Fielder for wheat gene transfer and genome editing study. | Xiaona Liang Xiaomin Bie Yuliang Qiu Ke Wang Zujun Yang Yuqi Jia Zhiying Xu Mei Yu Lipu Du Zhishan Lin Xingguo Ye | 2023 | The Crop Journal2023，11，2： | 2 |
| 8 | Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. | Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu | 2023 | Science China(Life Sciences)2023，66，5： | 2 |
| 9 | The GATA transcription factor TaGATA1 recruits demethylase TaELF6-A1 and enhances seed dormancy in wheat by directly regulating TaABI5显示文摘Seed dormancy is an important agronomic trait in crops, and plants with low dormancy are prone to preharvest sprouting(PHS) under high-temperature and humid conditions. In this study,we report that the GATA transcription factor TaGATA1 is a positive regulator of seed dormancy by regulating TaABI5 expression in wheat.Our results demonstrate that TaGATA1 overexpression significantly enhances seed dormancy and increases resistance to PHS in wheat. Gene expression patterns, abscisic acid(ABA) response assay, and transcriptome analysis all indicate that TaGATA1 functions through the ABA signaling pathway. The transcript abundance of TaABI5, an essential regulator in the ABA signaling pathway,is significantly elevated in plants overexpressing TaGATA1. Chromatin immunoprecipitation assay(ChIP) and transient expression analysis showed that TaGATA1 binds to the GATA motifs at the promoter of TaABI5 and induces its expression.We also demonstrate that TaGATA1 physically interacts with the putative demethylase TaELF6-A1, the wheat orthologue of Arabidopsis ELF6.ChIP–qPCR analysis showed that H3K27me3 levels significantly decline at the TaABI5 promoter in the TaGATA1-overexpression wheat line and that transient expression of TaELF6-A1 reduces methylation levels at the TaABI5 promoter, increasing TaABI5 expression. These findings reveal a new transcription module, including TaGATA1–TaELF6-A1–TaABI5, which contributes to seed dormancy through the ABA signaling pathway and epigenetic reprogramming at the target site. TaGATA1 could be a candidate gene for improving PHS resistance. | Xuening Wei Yuyan Li Xiuliang Zhu Xin Liu Xingguo Ye Miaoping Zhou Zengyan Zhang | 2023 | Journal of Integrative Plant Biology2023，65，5： | 1 |

| 11 | Development and genetic analysis of wheat double substitution lines carrying Hordeum vulgare 2H and Thinopyrum intermedium 2Ai#2 chromosomes显示文摘Thinopyrum intermedium and barley are two close relatives of wheat and carry many genes that are potentially valuable for the improvement of various wheat traits. In this study we created wheat double substitution lines by hybridizing different wheat–Th. intermedium and wheat–barley disomic alien substitution lines, with the aim of using genes in Th. intermedium and barley for wheat breeding and investigating the genetic behavior of alien chromosomes and their wheat homoeologs. As expected, we obtained two types of wheat double substitution lines,2D2Ai#2(2B)2H( A) and 2A2 Ai#2(2B)2H(2D), in which different group 2 wheat chromosomes were replaced by barley chromosome 2 H and Th. intermedium chromosome 2Ai#2. The new materials were characterized using molecular markers, genomic in situ hybridization(GISH), and fluorescent in situ hybridization(FISH). GISH and FISH experiments revealed that the double substitution lines harbor 42 chromosomes including 38 wheat chromosomes, a pair of barley chromosomes, and a pair of Th. intermedium chromosomes. Analysis using specific DNA markers showed that two pairs of wheat homoeologous group 2 chromosomes in the new lines were substituted by a pair of 2H and a pair of 2Ai#2 chromosomes. Chromosome 2H showed a higher transmission rate than 2Ai#2, and both chromosomes were preferentially transmitted between generations via female gametes. Evaluation of botanic and agronomic traits demonstrated that,compared with their parents, the new lines showed similar growth habits and plant type but differences in plant height, flowering date, and self-fertility. Cytological observations using different probes suggested that the double substitution lines showed nearly normal genetic behavior before and during meiosis. The novel substitution lines can potentially be used in wheat meiosis research and breeding programs. | Jing Wang Chang Liu Xianrui Guo Ke Wang Lipu Du Zhishan Lin Xingguo Ye | 2019 | The Crop Journal2019，7，2： | 1 |

| 14 | Development of a haploid inducer by editing HvMTL in barley显示文摘The doubled-haploid technique mediated by parthenogenesis and androgenesis in plants can directly generate homozygous diploid lines after chromosome doubling with colchicine in one or two generations,and this method undoubtedly shortens the breeding process and improves breeding efficiency in crops.Previously,haploid plants were mainly induced by anther culture or microspore culture via androgenesis(Ohnoutkova et al.,2019).In wheat(Triticum aestivum),haploids can also be induced by maize(Zea mays)pollen and chromosome elimination via parthenogenesis(Liu et al.,2020b).However,the aforementioned induction methods are genotype-dependent,require complex manipulations,and are both time-consuming and inefficient.Therefore,it is necessary to develop new techniques or germplasm for simple and efficient haploid induction. | Huali Tang Yuliang Qiu Wanxin Wang Mei Yu Yanan Chang Zhiyang Han Lipu Du Zhishan Lin Ke Wang Xingguo Ye | 2023 | Journal of Genetics and Genomics2023，50，5： | 1 |

| 16 | The soft glumes of common wheat are sterile-lemmas as determined by the domestication gene Q显示文摘The Q gene in common wheat encodes an APETALA2(AP2) transcription factor that causes the free threshing attribute. Wheat spikelets bearing several florets are subtended by a pair of soft glumes that allow free liberation of seeds. In wild species, the glumes are tough and rigid,making threshing difficult. However, the nature of these 'soft glumes', caused by the domestication allele Q is not clear. Here, we found that over expression of Q in common wheat leads to homeotic florets at glume positions. We provide phenotypic, microscopy, and marker genes evidence to demonstrate that the soft glumes of common wheat are in fact lemma-like organs, or so-called sterile-lemmas. By comparing the structures subtending spikelets in wheat and other crops such as rice and maize, we found that AP2 genes may play conserved functions in grasses by manipulating vestigial structures, such as floret-derived soft glumes in wheat and empty glumes in rice. Conversion of these seemingly vegetative organs to reproductive organs may be useful in yield improvement of crop species. | Gaoyuan Song Guoliang Sun Xingchen Kong Meiling Jia Ke Wang Xingguo Ye Yun Zhou Shuaifeng Geng Long Mao Aili Li | 2019 | The Crop Journal2019，7，1： | 1 |
| 17 | Concentration of n-3 polyunsaturated fatty acid glycerides by Candida antarctica lipase A-catalyzed selective methanolysis显示文摘n-3 polyunsaturated fatty acids(n-3 PUFA)have biologically important functions in human beings,but their contents in natural oils are usually low.This study investigated the concentration of n-3 PUFA-enriched glycerides by Candida antarctica lipase A(CAL-A)-catalyzed selective methanolysis of algal oil.First,lipases and acyl acceptors were screened.Subsequently,the methanolysis conditions including methanol concentration in aqueous solution,molar ratio of methanol to oil,reaction temperature,lipase loading and reaction time,were optimized.The results indicated that CAL-A could effectively identify n-3 PUFA during methanolysis.Saturated fatty acids and monounsaturated fatty acids were released from algal oil by CAL-A-catalyzed methanolysis,causing the production of n-3 PUFA-enriched glycerides.Under optimal conditions(3:1 of molar ratio of methanol to algal oil,20%methanol aqueous solution,6%CAL-A dosage,25℃,18 h),the n-3 PUFA content increased from the initial 45.96%to 73.96%,with an n-3 PUFA yield of 81.76%.The reusability of CAL-A demonstrated that under optimal conditions the lipase could be used for 8 times.Therefore,this enzymatic process is efficient for synthesis of n-3 PUFA-enriched glycerides. | Cong Jiang Ye Chen Yifan Wang Caiming Li Xiaosan Wang Zong Meng Xingguo Wang | 2022 | Food Bioscience2022，46，2： | 0 |
| 18 | Development of a wheat material with improved bread-making quality by overexpressing HMW-GS 1S^(l)x2.3^(*)from Aegilops longissima显示文摘Wheat bread-making quality can be improved by use of high-molecular-weight glutenin subunits(HMW-GSs)from wild relatives.Aegilops longissima is a close relative of wheat that contains a number of HMW-GS-encoding genes including 1S^(l)x2.3^(*).In this study,transgenic wheat lines overexpressing 1S^(l)x2.3^(*)were obtained by Agrobacterium-mediated transformation and used to investigate the genetic contribution of 1S^(l)x2.3^(*)to wheat flour-processing quality.The 1S^(l)x2.3^(*)transgene was stably inherited and expressed over generations.Expression of 1S^(l)x2.3^(*)increased the relative expression of 1Dx2 and 1Dy12 and reduced that of 1By18 during grain development.In general,integration of 1S^(l)x2.3^(*)stimulated the accumulation of endogenous HMW-GSs and low-molecular-weight glutenin subunits in wheat kernels,greatly increasing the glutenin:gliadin ratio and resulting in faster formation of protein bodies in the endosperm during grain development.A wheat material with improved flour-making quality was developed in which 1S^(l)x2.3^(*)improved wheat bread-making quality. | Yuliang Qiu Haiqiang Chen Shuangxi Zhang Jing Wang Lipu Du Ke Wang Xingguo Ye | 2022 | The Crop Journal2022，10，6： | 0 |
| 19 | A fast technique for visual screening of wheat haploids generated from TaMTL-edited mutants carrying anthocyanin markers显示文摘Dear Editor,Breeding a new wheat variety using traditional methods typically takes at least 8 to 10 years,and the breeding period can be dramatically shortened via a doubled haploid strategy,which can yield homozygotes within one or two generations.In the past several decades,wheat haploids have been widely induced through anther or microspore culture and chromosome elimination via interspecific hybridization between wheat and maize.The first technique exhibits strong genotype dependency and a severe albino phenomenon,whereas the latter shows low induction efficiency(Sangam et al.,2015).In addition,haploid induction procedures using the aforementioned methods are complicated to perform and require specialized equipment and environmentally controlled conditions.Thus,the application of these technologies in wheat breeding has been limited(Sangam et al.,2015). | Huali Tang Ke Wang Shuangxi Zhang Zhiyang Han Yanan Chang Yuliang Qiu Mei Yu Lipu Du Xingguo Ye | 2023 | Plant Communications2023，4，3： | 0 |
