| 1 | Activated Expression of WRKY57 Confers Drought Tolerance in Arabidopsis显示文摘干旱是限制世界范围的农业庄稼的生产率的最严肃的环境因素之一。然而,在植物位于干旱忍耐下面的机制是不清楚的。WRKY 抄写因素被知道在改编工作到不能生活的压力。由屏蔽联系 WRKY 的 T-DNA 插入异种的一个水池,我们孤立 gain-of-function 变异的、获得的干旱忍耐(adt ) ,出现改进干旱忍耐。在干旱压力条件下面, adt 比野类型的植物积累了骆驼毛的织物的高水平。有气孔的孔分析显示 adt 比野类型的植物对骆驼毛的织物更敏感。分子的基因分析表明在 adt 的 T-DNA 插入导致了编码 WRKR57 蛋白质的 WRKY 基因的激活的表示。WRKY57 的组成的表示也授与类似的干旱忍耐。一致地与高骆驼毛的织物内容和提高的干旱忍耐,三压力应答的基因(RD29A, NCED3,和 ABA3 ) 在 adt 是起来调整的。薄片试金证明 WRKY57 能直接绑 RD29A 和 NCED3 倡导者序列的 W 盒子。在骆驼毛的织物处理期间,,另外,种子萌芽和 adt 的早幼苗生长在高渗透的条件下面被禁止, adt 显示出更高的种子萌芽频率。在摘要,我们的结果建议 WRKY57 的激活的表示由骆驼毛的织物层次的举起改进了 Arabidopsis 的干旱忍耐。WRKY57 的功能的建立将通过基因操作途径启用植物干旱忍耐的改进。 | Yanjuan Jiang Gang Liang Diqiu Yu | 2012 | Molecular Plant2012，5，6： | 62 |
| 2 | Arabidopsis WRKY Transcription Factors WRKY12 and WRKY13 Oppositely Regulate Flowering under Short-Day Conditions显示文摘在植物,光周期是为决定 flowering 的重要暗示。在 Arabidopsis thaliana 的花的转变是更早的在下面长天(LD ) 比在下面短天(SD ) 条件。在 SD 条件下面的 Arabidopsis 植物的 Flowering 被植物荷尔蒙赤霉素(GA ) 主要调整。这里,我们报导二个 WRKY 抄写因素在在 SD 条件下面控制 flowering 时间相对地工作。Phenotypic 分析证明 WRKY12 的那混乱在 flowering 引起了延期,当 WRKY13 功能的损失支持了 flowering 时。WRKY12 和 WRKY13 连续地显示了否定地相关的表示侧面和功能调整 flowering。分子、基因的分析证明 FRUITFULL (FUL ) 是 WRKY12 和 WRKY13 的直接下游的目标基因。有趣地,我们发现那 DELLA 蛋白质赤霉素感觉迟钝(GAI ) 并且 RGA-LIKE1 (RGL1 ) 与 WRKY12 和 WRKY13 交往了,并且他们的相互作用防碍 WRKY12 和 WRKY13 的 transcriptional 活动。进一步的研究建议 thatWRKY12 和 WRKY13 部分调停了控制 flowering 时间上的 GA 3 的效果。一起拿,我们的结果显示 WRKY12 和 WRKY13 相对地在 SD 条件下面调制 flowering 时间,它部分至少包含 GA 的行动。 | Wei Li Houping Wang Diqiu Yu | 2016 | Molecular Plant2016，9，11： | 33 |
| 3 | Overexpression of the stress-induced OsWRKY08 improves osmotic stress tolerance in Arabidopsis显示文摘Previous Northern blotting analyses of rice seedlings have screened several WRKY genes among the transcripts that are differentially regulated in the following treatments: high salinity, cold stress, polyethylene glycol (PEG) and heat shock. Here, we report characterization of a WRKY gene, OsWRKY08, in rice, which was found to be inducible by PEG, NaCl, Abscisic acid (ABA), and naphthalene acetic acid (NAA) as its ortholog AtWRKY28 in Arabidopsis. To determine whether overexpression of OsWRKY08 alters abiotic stress tolerance, 35S::OsWRKY08 recombinant was generated and transformed into Arabidopsis. Physiological tests indicated that 35S::OsWRKY08 transgenic Arabidopsis displayed increased tolerance to mannitol stress through increasing the lateral root number and primary root length during seeding root development. Further, semi-quantitative RT-PCR showed that AtCOR47 and AtRD21, two ABA-independent abiotic stress responded genes, were induced in 35S::OsWRKY08 transgenic plants. These results suggest OsWRKY08 improves the osmotic stress tolerance of transgenic Arabidopsis through an ABA-independent signaling pathway. | SONG Yu JING ShaoJuan YU DiQiu | 2009 | Chinese Science Bulletin2009，54，24： | 22 |

| 5 | Control of sulfate concentration by miR395-targeted APS genes in Arabidopsis thaliana显示文摘Sulfur nutrition is crucial for plant growth and development,as well as crop yield and quality.Inorganic sulfate in the soil is the major sulfur source for plants.After uptake,sulfate is activated by ATP sulfurylase,and then gets assimilated into sulfur-containing metabolites.However,the mechanism of regulation of sulfate levels by ATP sulfurylase is unclear.Here,we investigated the control of sulfate levels by miR395-mediated regulation of APS1/3/4.Sulfate was over-accumulated in the shoots of miR395 over-expression plants in which the expression of the APS1,APS3,and APS4 genes was suppressed.Accordingly,reduced expression of miR395 caused a decline of sulfate concentration.In agreement with these results,over-expression of the APS1,APS3,and APS4 genes led to the reduction of sulfate levels.Differential expression of these three APS genes in response to sulfate starvation implied that they have different functions.Further investigation revealed that the regulation of sulfate levels mediated by miR395 depends on the repression of its APS targets.Unlike the APS1,APS3,and APS4 genes,which encode plastid-localized ATP sulfurylases,the APS2 gene encodes a cytosolic version of ATP sulfurylase.Genetic analysis indicated that APS2 has no significant effect on sulfate levels.Our data suggest that miR395-targeted APS genes are key regulators of sulfate concentration in leaves. | Qin Ai Gang Liang Huimin Zhang Diqiu Yu | 2016 | 植物分类与资源学报2016，38，2： | 9 |
| 6 | Analysis of genetic architecture and favorable allele usage of agronomic traits in a large collection of Chinese rice accessions显示文摘Genotyping and phenotyping large natural populations provide opportunities for population genomic analysis and genome-wide association studies(GWAS). Several rice populations have been re-sequenced in the past decade;however, many major Chinese rice cultivars were not included in these studies. Here, we report large-scale genomic and phenotypic datasets for a collection mainly comprised of 1,275 rice accessions of widely planted cultivars and parental hybrid rice lines from China. The population was divided into three indica/Xian and three japonica/Geng phylogenetic subgroups that correlate strongly with their geographic or breeding origins. We acquired a total of 146 phenotypic datasets for 29 agronomic traits under multi-environments for different subpopulations. With GWAS, we identified a total of 143 significant association loci, including three newly identified candidate genes or alleles that control heading date or amylose content. Our genotypic analysis of agronomically important genes in the population revealed that many favorable alleles are underused in elite accessions, suggesting they may be used to provide improvements in future breeding efforts. Our study provides useful resources for rice genetics research and breeding. | Xiuxiu Li Zhuo Chen Guomin Zhang Hongwei Lu Peng Qin Ming Qi Ying Yu Bingke Jiao Xianfeng Zhao Qiang Gao Hao Wang Yunyu Wu Juntao Ma Liyan Zhang Yongli Wang Lingwei Deng Shanguo Yao Zhukuang Cheng Diqiu Yu Lihuang Zhu Yongbiao Xue Chengcai Chu Aihong Li Shigui Li Chengzhi Liang | 2020 | Science China(Life Sciences)2020，63，11： | 8 |
| 7 | Arabidopsis VQ10 interacts with WRKY8 to modulate basal defense against Botrytis cinerea显示文摘Recent studies in Arabidopsis have revealed that some VQ motif-containing proteins physically interact with WRKY transcription factors;however,their specific biological functions are still poorly understood.In this study,we confirmed the interaction between VQ10and WRKY8,and show that VQ10 and WRKY8 formed a complex in the plant cell nucleus.Yeast two-hybrid analysis showed that the middle region of WRKY8 and the VQ motif of VQ10 are critical for their interaction,and that this interaction promotes the DNA-binding activity of WRKY8.Further investigation revealed that the VQ10protein was exclusively localized in the nucleus,and VQ10was predominantly expressed in siliques.VQ10 expression was strongly responsive to the necrotrophic fungal pathogen,Botrytis cinerea and defense-related hormones.Phenotypic analysis showed that disruption of VQ10 increased mutant plants susceptibility to the fungal pathogen B.cinerea,whereas constitutive-expression of VQ10 enhanced resistance to B.cinerea.Consistent with these findings,expression of the defenserelated PLANT DEFENSIN1.2(PDF1.2)gene was decreased in vq10 mutant plants,after B.cinerea infection,but increased in VQ10-overexpressing transgenic plants.Taken together,our findings provide evidence that VQ10 physically interacts with WRKY8 and positively regulates plant basal resistance against the necrotrophic fungal pathogen B.cinerea. | Junqiu Chen Houping Wang Yang Li Jinjing Pan Yanru Hu Diqiu Yu | 2018 | Journal of Integrative Plant Biology2018，60，10： | 8 |
| 8 | WRKY transcription factors WRKY12 and WRKY13 interact with SPL10 to modulate age-mediated flowering显示文摘WRKY12 and WRKY13 are two WRKY transcription factors that play important roles in the control of flowering time under short-day(SD)conditions.The temporally regulated expression of WRKY12 and WRKY13 indicates that they may be involved in the age-mediated flowering pathway.However,their roles in this pathway are poorly understood.Here,we show that the transcription of WRKY12 and WRKY13 is directly regulated by SQUAMOSA PROMOTER BINDING-LIKE 10(SPLio),a transcription factor downstream of the age pathway.Binding and activation analyses revealed that SPL10 functions as a positive regulator of WRKY12 and a negative regulator of WRKY13.Further mechanistic investigation revealed that WRKY12 and WRKY13 physically interact with SPL10 and that both of them bind to the promoter of miRiy2b.Thus,the WRKY12-SPL10 and WRKY13-SPL10 interactions facilitate and inhibit SPL10 transcriptional function,respectively,to regulate miRiy2b expression.Together,our results show that WRKY12 and WRKY13 participate in the control of age-mediated flowering under SD conditions though physically interacting with SPLs and co-regulating the target gene miRi72b. | Zhenbing Ma Wei Li Houping Wang Diqiu Yu | 2020 | Journal of Integrative Plant Biology2020，62，11： | 8 |
| 9 | WRKY transcription factors: links between phytohormones and plant processes显示文摘WRKY transcription factors,which form integral parts of signaling webs that modulate many plant processes,are one of the largest families of transcriptional regulators in plants.More and more findings demonstrate that WRKY transcription factors function as repressors as well as activators。 | JIANG YanJuan YU DiQiu | 2015 | Science China(Life Sciences)2015，58，5： | 5 |
| 10 | Trehalose phosphate synthase 5-dependent trehalose metabolism modulates basal defense responses in Arabidopsis thaliana显示文摘Despite the recent discovery that trehalose synthesis is important for plant development and abiotic stress tolerance, the effects of trehalose on biotic stress responses remain relatively unknown. In this study, we demonstrate that TREHALOSE PHOSPHATE SYNTHASE 5(TPS5)-dependent trehalose metabolism regulates Arabidopsis thaliana defenses against pathogens(necrotrophic Botrytis cinerea and biotrophic Pseudomonas syringae).Pathogen infection increased trehalose levels and upregulated TPS5 expression. Application of exogenous trehalose significantly improved plant defenses against B. cinerea, but increased the susceptibility of plants to P. syringae. We demonstrate that elevated trehalose biosynthesis, in transgenic plants over-expressing TPS5, also increased the susceptibility to P. syringae, but decreased the disease elcit r symptoms caused by B. cinerea. The knockout of TPS5 prevented the accumulation of trehalose and enhanced defense responses against P. syringae. Additionally, we observed that a TPS5-interacting protein(multiprotein bridging factor 1c) was required for induced expression of TPS5 during pathogen infections. Furthermore, we show that trehalose promotes P. syringae growth and disease development, via a mechanism involving suppression of the plant defense gene, Pathogenesis-Related Protein 1. These findings provide insight into the function of TPS5-dependent trehalose metabolism in plant basal defense responses. | Xuelan Wang Yan Du Diqiu Yu | 2019 | Journal of Integrative Plant Biology2019，61，4： | 5 |
| 11 | bHLH104 confers tolerance to cadmium stress in Arabidopsis thaliana显示文摘Cd is a non-essential heavy metal that is toxic to both plants and animals. Here, we reveal that the transcription factor bHLH104 positively regulates Cd tolerance in Arabidopsis thaliana. We show that Fe deficiency-responsive genes were induced by Cd treatment, and that their upregulation was suppressed in bhlh104 loss-of-function mutants, but enhanced upon overexpression of bHLH104. Correspondingly, the bhlh104 mutants displayed sensitivity to Cd stress, whereas plants overexpressing bHLH104 exhibited enhanced Cd tolerance.Further analysis suggested that bHLH104 positively regulates four heavy metal detoxification-associated genes, IREG2, MTP3, HMA3 and NAS4, which play roles in Cd sequestration and tolerance. The bHLH104 overexpression plants accumulated high levels of Cd in the root but low levels of Cd in the shoot, which might contribute to the Cd tolerance in those lines. The present study thus points to bHLH104 as a potentially useful tool for genetic engineering of plants with enhanced Cd tolerance. | Xiani Yao Yuerong Cai Diqiu Yu Gang Liang | 2018 | Journal of Integrative Plant Biology2018，60，8： | 4 |
| 12 | 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 |
| 13 | Mapping and breeding value evaluation of a semi-dominant semidwarf gene in upland rice显示文摘Plant height is an important trait related to yield potential and plant architecture.A suitable plant height plays a crucial role in improvement of rice yield and lodging resistance.In this study,we found that the traditional upland landrace 'Kaowenghan'(KWH) showed a special semi-dwarf phenotype.To identify the semi-dwarf gene from KWH,we raised BC2 F4 semi-dwarf introgression lines(IL) by hybridization of the japonica rice cultivar 'Dianjingyou1'(DJY1) and KWH in a DJY1 background.The plant height of the homozygous semi-dwarf IL(IL-87) was significantly reduced compared with that of DJY1.The phenotype of the F1 progeny of the semi-dwarf IL-87 and DJY1 showed that the semi-dwarf phenotype was semidominant.QTL mapping indicated that the semi-dwarf phenotype was controlled by a major QTL q DH1 and was localized between the markers RM6696 and RM12047 on chromosome 1.We also developed near-isogenic lines(NIL) from the BC3 F3 population,and found that the yield of homozygous NIL(NIL-2)was not significantly different compared to DJY1.Breeding value evaluation through investigation of the plant height of the progeny of NIL(NIL-2) and cultivars from different genetic background indicate that the novel semi-dwarf gene shows potential as a genetic resource for rice breeding. | Xiaoqian Chen Peng Xu Jiawu Zhou Dayun Tao Diqiu Yu | 2018 | Plant Diversity2018，40，5： | 3 |
| 14 | MicroRNA (miR396) negatively regulates expression of ceramidase-like genes in Arabidopsis显示文摘MicroRNAs (miRNAs) are 21-23 nucleotide (nt), endogenous RNAs that regulate gene expression by targeting mRNAs for direct cleavage or translational repression in plants. In Arabidopsis, miR396 is encoded by two different loci (MIR396a and MIR396b) and sequence analysis suggests it may target three ceramidase-like genes (Atceramidase-like 1, Atceramidase-like 2 and Atceramidase-like 3). To demonstrate the biological function of miR396, we inserted the synthetic precursors, MIR396a or MIR396b, under the control of the enhanced cauliflower mosaic virus (CaMV) 35S promoter, into a plant transformation vector (pOCA30) and transformed the constructs into Arabidopsis. The promoter increased miR396 levels by more than 2-fold, indicating appropriate maturation of the synthetic precursor MIR396a or MIR396b transcript in transgenic plants. Microarray analysis showed that the transcript levels of two ceramidase-like genes (Atceramidase-like 1, Atceramidase-like 2) were decreased by more than 2-fold and lactosylceramide 4-a-galactosyltransferase increased by more than 2-fold in transgenic plants compared with the empty vector-transformed plants. Northern blot analysis showed that the mRNA levels of the two ceramidase-like genes were significantly reduced in transgenic plants. These results indicated that miR396 probably plays a crucial role in the ceramide metabolism pathway by negatively regulating the expression of ceramidase-like genes in Arabidopsis. | Dongmei Liu Diqiu Yu | 2009 | Progress in Natural Science:Materials International2009，19，6： | 2 |
| 15 | ERF1 delays flowering through direct inhibition of FLOWERING LOCUS T expression in Arabidopsis显示文摘ETHYLENE RESPONSE FACTOR1(ERF1)is a key component in ethylene signaling,playing crucial roles in both biotic and abiotic stress responses.Here,we demonstrate that ERF1 also has an important role during floral initiation in Arabidopsis thaliana.Knockdown or knockout of ERF1 accelerated floral initiation,whereas overexpression of ERF1 dramatically delayed floral transition.These contrasting phenotypes were correlated with opposite transcript levels of FLOWERING LOCUS T(FT).Chromatin immunoprecipitation(ChIP)assays revealed that ERF1 associates with genomic regions of the FT gene to repress its transcription.ft-10/ERF1RNAi plants showed a similar flowering phenotype to the ft-10 mutant,whereas the flowering of FTox/ERF1ox mimicked that of FTox plants,suggesting that ERF1 acts upstream of FT during floral initiation.Similarly,altered floral transition in ethylene-related mutants was also correlated with FT expression.Further analysis suggested that ERF1 also participates in delay in flowering-time control mediated by the ethylene precursor 1-aminocyclopropane-1-carboxylic acid.Thus,ERF1 may act as a negative modulator of flowering-time control by repressing FT transcription in Arabidopsis. | Yanli Chen Liping Zhang Haiyan Zhang Ligang Chen Diqiu Yu | 2021 | Journal of Integrative Plant Biology2021，63，10： | 2 |
| 16 | Natural alleles of a uridine 5'-diphospho-glucosyltransferase gene responsible for differential endosperm development between upland rice and paddy rice显示文摘Traditional upland rice generally exhibits insufficient grains resulting from abnormal endosperm development compared to paddy rice. However, the underlying molecular mechanism of this trait is poorly understood. Here,we cloned the uridine 5’-diphospho(UDP)-glucosyltransferase gene EDR1(Endosperm Development in Rice) responsible for differential endosperm development between upland rice and paddy rice by performing quantitative trait loci analysis and map-based cloning. EDR1 was highly expressed in developing seeds duringgrain filling. Natural variations in EDR1 significantly reduced the UDP-glucosyltransferase activity of EDR1 YZNcompared to EDR1 YD1,resulting in abnormal endosperm development in the near-isogenic line, accompanied by insufficient grains and changes in grain quality.By analyzing the distribution of the two alleles EDR1 YD1 and EDR1 YZNamong diverse paddy rice and upland rice varieties, we discovered that EDR1 was conserved in upland rice, but segregated in paddy rice. Further analyses of grain chalkiness in the alleles of EDR1 YD1 and EDR1 YZNvarieties indicated that rice varieties harboring EDR1 YZNand EDR1 YD1 preferentially showed high chalkiness, and low chalkiness,respectively. Taken together, these results suggest that the UDP-glucosyltransferase gene EDR1 is an important determinant controlling differential endosperm development between upland rice and paddy rice. | Zihao Wu Xiao Zhang Guimei Chang Jun Yang Jinpeng Wan Feijun Wang Dayun Tao Jiawu Zhou Lianguang Shang Peng Xu Diqiu Yu | 2022 | Journal of Integrative Plant Biology2022，64，1： | 1 |
| 17 | Functional characterization of the Arabidopsis SERRATE under salt stress显示文摘SERRATE(SE)plays critical roles in RNA metabolism and plant growth regulation.However,its function in stresseresponse processes remains largely unknown.Here,we examined the regulatory role of SE using the se-1 mutant and its complementation line under saline conditions.The expression of SE was repressed by salt treatment at both mRNA and protein levels.After treatment with different NaCl concentrations,the se-1 mutants showed increased sensitivity to salinity.This heightened sensitivity was evidenced by decreased germination,reduced root growth,more serious chlorosis,and increased conductivity of the mutants compared with the wild type.Further analysis revealed that SE regulates the pre-mRNA splicing of several well-characterized marker genes associated with salt stress tolerance.Our data thus imply that SE may function as a key component in plant response to salt stress by modulating the splicing of salt stress-associated genes. | Minghui Mou Qijuan Wang Yanli Chen Diqiu Yu Ligang Chen | 2021 | Plant Diversity2021，43，1： | 1 |
