| 1 | Genetic analysis of tolerance to photo-oxidative stress induced by high light in winter wheat (Triticum aestivum L.)显示文摘High light induced photooxidation (HLIP) usually leads to leaf premature senescence and causes great yield loss in winter wheat. In order to explore the genetic control of wheat tolerance to HLIP stress, a quantitative trait loci (QTL) analysis was conducted on a set of doubled haploid population, derived from two winter wheat cultivars. Actual values of chlorophyll content (Chl), minimum fluorescence level (Fo), maximum fluorescence level (Fm), and the maximum quantum efficiency of photosystem II (Fv/Fm) under both HLIP and non-stress conditions as well as the ratios of HLIP to non-stress were evaluated. HLIP considerably reduced Chl, Fm, and Fv/Fm, but in-creased Fo, compared with that under non-stress condition. A total of 27, 16, and 28 QTLs were associated with the investigated traits under HLIP and non-stress and the ratios of HLIP to non-stress, respectively. Most of the QTLs for the ratios of HLIP to non-stress collocated or nearly linked with those detected under HLIP condition. HLIP-induced QTLs were mapped on 15 chromosomes, involving in 1A, 1B, 1D, 2A, 2B, 2D, 3A, 3B, 4A, 4D, 5B, 6A, 6B, 7A, and 7D while those expressed under non-stress condition involved in nine chromosomes, includ-ing 1B, 1D, 2A, 2B, 3B, 4A, 5A, 5B, and 7A. The expression patterns of QTLs under HLIP condition were different from that under non-stress condition except for six loci on five chromosomes. The phenotypic variance explained by individual QTL ranged from 5.0% to 19.7% under HLIP, 8.3% to 20.8% under non-stress, and 4.9% to 20.2% for the ratios of HLIP to non-stress, respectively. Some markers, for example, Xgwm192 and WMC331 on 4D regulating Chl, Fo, Fm, and Fv/Fm under HLIP condition, might be used in marker assistant selection. | Hongwei Li Yiping Tong Bin Li Ruilian Jing Congming Lu Zhensheng Li | 2010 | Journal of Genetics and Genomics2010，37，6： | 10 |
| 2 | Molecular characterization and expression analysis of Triticum aestivum squamosa-promoter binding protein-box genes involved in ear development显示文摘Wheat(Triticum aestivum L.) is one of the most important crops in the world. Squamosa-promoter binding protein(SBP)-box genes play a critical role in regulating flower and fruit development. In this study, 10 novel SBP-box genes(TaSPL genes) were isolated from wheat((Triticum aestivum L.) cultivar Yanzhan 4110). Phylogenetic analysis classified the TaSPL genes into five groups(G1–G5). The motif combinations and expression patterns of the TaSPL genes varied among the five groups with each having own distinctive characteristics: TaSPL20/21 in G1 and TaSPL17 in G2 mainly expressed in the shoot apical meristem and the young ear, and their expression levels responded to development of the ear; TaSPL6/15 belonging to G3 were upregulated and TaSPL1/23 in G4 were downregulated during grain development; the gene in G5(TaSPL3) expressed constitutively. Thus, the consistency of the phylogenetic analysis, motif compositions, and expression patterns of the TaSPL genes revealed specific gene structures and functions.On the other hand, the diverse gene structures and different expression patterns suggested that wheat SBP-box genes have a wide range of functions. The results also suggest a potential role for wheat SBP-box genes in ear development.This study provides a significant beginning of functional analysis of SBP-box genes in wheat. | Bin Zhang Xia Liu Guangyao Zhao Xinguo Mao Ang Li Ruilian Jing | 2014 | Journal of Integrative Plant Biology2014，56，6： | 7 |
| 3 | Genetic Analysis of Carbon Isotope Discrimination and its Relation to Yield in a Wheat Doubled Haploid Population显示文摘Carbon isotope discrimination(△13C) is considered a useful indicator for indirect selection of grain yield(GY) in cereals.Therefore,it is important to evaluate the genetic variation in △13C and its relationship with GY.A doubled haploid(DH) population derived from a cross of two common wheat varieties,Hanxuan 10(H10) and Lumai 14(L14),was phenotyped for △13C in the flag leaf,GY and yield associated traits in two trials contrasted by water availability,specifically,rain-fed and irrigated.Quantitative trait loci(QTLs) were identified by single locus and two locus QTL analyses.QTLs for △13C were located on chromosomes 1A,2B,3B,5A,7A and 7B,and QTLs for other traits on all chromosomes except 1A,4D,5A,5B and 6D.The population selected for high △13C had an increased frequency of QTL for high △13C,GY and number of spikes per plant(NSP) when grown under rain-fed conditions and only for high △13C and NSP when grown under irrigated conditions,which was consistent with agronomic performance of the corresponding trait values in the high △13C progeny;that is,significantly greater than that in the low △13C.Therefore,selection for △13C was beneficial in increasing grain yield in rain-fed environments. | Xianshan Wu Xiaoping Chang Ruilian Jing | 2011 | Journal of Integrative Plant Biology2011，53，9： | 6 |
| 4 | Quantitative Trait Loci Mapping of Dark-Induced Senescence in Winter Wheat(Triticum aestivum)显示文摘In order to explore the genetics of dark-induced senescence in winter wheat(Triticum aestivum L.),a quantitative trait loci(QTL)analysis was carried out in a doubled haploid population developed from a cross between the varieties Hanxuan 10(HX)and Lumai 14(LM).The senescence parameters chlorophyll content(Chl a+b,Chl a,and Chl b),original fluorescence(Fo),maximum fluorescence level(Fm),maximum photochemical efficiency(Fv/Fm),and ratio of variable fluorescence to original fluorescence(Fv/Fo)were evaluated in the second leaf of whole three-leaf seedlings subjected to 7 d of darkness.A total of 43 QTLs were identified that were associated with dark-induced senescence using composite interval mapping.These QTLs were mapped to 20 loci distributed on 11 chromosomes:1B,1D,2A,2B,3B,3D,5D,6A,6B,7A,and 7B.The phenotypic variation explained by each QTL ranged from 7.5% to 19.4%.Eleven loci coincided with two or more of the analyzed parameters.In addition,14 loci co-located or were linked with previously reported QTLs regulating flag leaf senescence,tolerance to high light stress,and grain protein content(Gpc),separately. | Hongwei Li Fanyun Lin Gui Wang Ruilian Jing Qi Zheng Bin Li Zhensheng Li | 2012 | Journal of Integrative Plant Biology2012，54，1： | 6 |
| 5 | Genetic analysis of biomass and photosynthetic parameters in wheat grown in different light intensities显示文摘Growth light intensities largely determine photosynthesis, biomass, and grain yield of cereal crops. To explore the genetic basis of light responses of biomass and Researchphotosynthetic parameters in wheat(Triticum aestivum L.),a quantitative trait locus(QTL) analysis was carried out in a doubled haploid(DH) population grown in low light(LL),medium light(ML), and high light(HL), respectively. The results showed that the wheat seedlings grown in HL produced more biomass with lower total chlorophyll content(Chl), carotenoid content, and maximum photochemical efficiency of photosystem II(Fv/Fm) while the wheat seedlings grown in LL produced less biomass with higher Chl compared with those grown in ML. In total, 48 QTLs were identified to be associated with the investigated parameters in relation to growth light intensities. These QTLs were mapped to 15 chromosomes which individually explained6.3%–36.0% of the phenotypic variance, of which chromo-somes 3A, 1D, and 6B were specifically involved in LL response, 5D and 7A specifically involved in ML response,and 4B specifically involved in HL response. Several light-responsive QTLs were co-located with QTLs for photosynthetic parameters, biomass, and grain weight under various conditions which may provide new hints to uncover the genetic control of photosynthesis, biomass, and grain weight. | Hongwei Li Gui Wang Qi Zheng Bin Li Ruilian Jing Zhensheng Li | 2014 | Journal of Integrative Plant Biology2014，56，6： | 2 |
| 6 | DIW1 encoding a cladeⅠPP2C phosphatase negatively regulates drought tolerance by de-phosphorylating TaSnRK1.1 in wheat显示文摘Drought seriously impacts wheat production(Triticum aestivum L.),while the exploitation and utilization of genes for drought tolerance are insufficient.Leaf wilting is a direct reflection of drought tolerance in plants.Clade A PP2Cs are abscisic acid(ABA)co-receptors playing vital roles in the ABA signaling pathway,regulating drought response.However,the roles of other clade PP2Cs in drought tolerance,especially in wheat,remain largely unknown.Here,we identified a gain-of-function drought-induced wilting 1(DIW1)gene from the wheat Aikang 58 mutant library by map-based cloning,which encodes a cladeⅠprotein phosphatase 2C(TaPP2C158)with enhanced protein phosphatase activity.Phenotypic analysis of overexpression and CRISPR/Cas9 mutant lines demonstrated that DIW1/TaPP2C158 is a negative regulator responsible for drought resistance.We found that TaPP2C158 directly interacts with TaSnRK1.1 and de-phosphorylates it,thus inactivating the TaSnRK1.1–Ta AREB3 pathway.TaPP2C158 protein phosphatase activity is negatively correlated with ABA signaling.Association analysis suggested that C-terminal variation of TaPP2C158 changing protein phosphatase activity is highly correlated with the canopy temperature,and seedling survival rate under drought stress.Our data suggest that the favorable allele with lower phosphatase activity of TaPP2C158 has been positively selected in Chinese breeding history.This work benefits us in understanding the molecular mechanism of wheat drought tolerance,and provides elite genetic resources and molecular markers for improving wheat drought tolerance. | Jingyi Wang Chaonan Li Long Li Lifeng Gao Ge Hu Yanfei Zhang Matthew P.Reynolds Xueyong Zhang Jizeng Jia Xinguo Mao Ruilian Jing | 2023 | Journal of Integrative Plant Biology2023，65，8： | 1 |

| 14 | Effective alleviation of Cd stress to microbial communities in mining reclamation soils by thiourea-modified biochar amendment显示文摘Reclaimed soils in mining area usually display low fertility and present Cd stress.The amendment of modified biochar effectively fixes Cd in soils,enhances soil fertility,and reduces Cd stress in soil microorganisms.However,the effect of thiourea-modified biochar(TBC)on microbial adaptability to Cd stress in mining reclamation soils is still unclear.The present work studied the Cd immobilization and microbial community changes in a mining reclamation soil displaying extreme Cd contamination under TBC amendment.The results indicated that the amendment of TBC significantly enhanced(P<0.05)soil pH,the content of available phosphorus(AP),and the activities of urease and polyphenol oxidase by 1.3%,463.4%,54.4%,and 84.0%,respectively,compared to the control without amendment.The amount of toxicity characteristic leaching procedure-extracable Cd decreased(P<0.05)by 68.0%in the TBC-amended soil compared with the unamended soil.The structure of soil microbiota was reorganized and the alpha diversity index was increased in the TBC treatment.The TBC amendment increased the relative abundances of Proteobacteria,Bacteroidota,and Zoopagomycota,which were strongly associated(P<0.01)with higher soil pH and AP.Structural equation model results demonstrated that Cd immobilization was directly influenced by soil pH,AP,and urease,and indirectly affected by bacterial structure in the TBC treatment.The TBC amendment can effectively improve the structural composition of soil bacteria under Cd stress and enhance the pathways of decreasing soil Cd availability as well.The results might facilitate the development of in-situ remediation programs in Cd-contaminated soils in the future. | Yanfeng ZHU Jing MA Fu CHEN Ruilian YU Gongren HU Yongjun YANG | 2022 | Pedosphere2022，32，6： | 0 |
| 15 | Relation of Leaf Stomatal Traits to Yield and Drought Resistance of Wheat显示文摘[Objective]The study aimed to discuss the relation of leaf stomatal traits to yield and drought resistance of wheat. [Method]Using the DH population of wheat cultivar Hanxuan10/Lumai14 as the test object,the relation of leaf stomatal density (SD) ,length (SL) and width (SW) , stomatal conductance (gs) ,photosynthetic rate (Pn) ,transpiration rate (Tr) to grain yield per plant and index of drought resistance (IDR) on the 10 th and 20 th day after anthesis under the conditions of drought stress and normal irrigation were discussed by the methods of correlation analysis and path analysis. [Result]Under the two water conditions,the correlations of these stomatal traits with yield components and IDR were mostly not significant on the 10 th day after anthesis,but there were significantly positive correlations between thousand kernel weight (TKW) and these traits on the 20 th day after anthesis. Path analysis showed that gs,Pn and Tr were main factors affecting yield per plant (YPP) and IDR,and they had stronger direct effects on YPP and IDR,while their indirect interaction was also strong. The direct effects of SD,SL and SW on YPP and IDR were small,as well as their indirect action among SD,SL and SW. On the other hand,the correlations between SD and SL were significant,and the correlations of SL with SW,gs,Pn and Tr were extremely significant on the 10 th and 20 th day after anthesis under the two water conditions. However, the correlations of SD and SL with gs,Pn,and Tr changed with water conditions or growth stages,showing that water conditions or growth stages had great effects on the correlations between two traits. Therefore,it is not always a good means to improve stomatal conductance,photosynthetic rate and transpiration rate and hence promote wheat yield by selecting stomatal density and size. [Conclusion]The research could provide scientific references for revealing the roles of leaf stomatal traits in wheat breeding for drought resistance. | Zhongqing Li Shoushan Jia Daizhen Sun Shuguang Wang Yugang Shi Hua Fan Zenghao Liang Ruilian Jing | 2013 | Meteorological and Environmental Research2013，4，5： | 0 |
