| 1 | The involvement of wheat U-box E3 ubiquitin ligase TaPUB1 in salt stress tolerance显示文摘U-box E3 ubiquitin ligases play important roles in the ubiquitin/26 S proteasome machinery and in abiotic stress responses. Ta PUB1-overexpressing wheat(Triticum aestivum L.) were generated to evaluate its function in salt tolerance. These plants had more salt stress tolerance during seedling and flowering stages, whereas the Ta PUB1-RNA interference(RNAi)-mediated knock-down transgenic wheat showed more salt stress sensitivity than the wild type(WT). Ta PUB1 overexpression upregulated the expression of genes related to ion channels and increased the net root Na+efflux, but decreased the net K+efflux and H+influx, thereby maintaining a low cytosolic Na+/K+ratio, compared with the WT. However,RNAi-mediated knock-down plants showed the opposite response to salt stress. Ta PUB1 could induce the expression of some genes that improved the antioxidant capacity of plants under salt stress. Ta PUB1 also interacted with Ta MP(Triticum aestivum α-mannosidase protein), a regulator playing an important role in salt response in yeast and in plants. Thus, low cytosolic Na+/K+ratios and better antioxidant enzyme activities could be maintained in wheat with overexpression of Ta PUB1 under salt stress. Therefore, we conclude that the U-box E3 ubiquitin ligase Ta PUB1 positively regulates salt stress tolerance in wheat. | Wenlong Wang Wenqiang Wang Yunzhen Wu Qinxue Li Guangqiang Zhang Ruirui Shi Junjiao Yang Yong Wang Wei Wang | 2020 | Journal of Integrative Plant Biology2020，62，5： | 6 |
| 2 | Energy-level dependent H_2_O_2 production on metal-free,carbon-content tunable carbon nitride photocatalysts显示文摘Light-driven production of H_2O_2 from water and molecular oxygen could be a promising way for obtaining both solar fuels and fundamental chemicals. During that process, the H_2O_2 yield is strongly dependent on the reaction pathway associated with two-electron reduction of dioxygen by the photo-generated electrons. Herein, we synthesized a series of metal-free, carbon-content tunable carbon nitride photocatalysts(named C_3N_4-Carbon) by a facile hydrothermal reaction and subsequent thermal treatment at appropriate temperatures. The energy levels of the C_3N_4-Carbon catalysts vary with the carbon doping level, which is conveniently tuned by changing the initial glucose concentration during the hydrothermal reaction. The surface carbon species evolve with the carbon content and the nitrogen atoms in the structure of carbon nitride are partially substituted by foreign carbon atoms based on XPS measurements. The optimal catalyst leads to the highest H_2O_2 yield of 1271 μmol L^(-1) in an acidic aqueous solution(pH 3) after a reaction period of 4 h, twice higher than the pristine C_3N_4. In addition, the largest formation rate constant and the smallest decomposition rate constant of H_2O_2 are obtained on the optimal one according to the kinetics analyses. The decomposition tests of H_2O_2 indicate that the formation rate could be a dominant factor impacting the H_2O_2 yield. The conduction band position of the optimal catalyst is positively shifted to 0.06 V versus RHE, which is more favorable to the reduction of dioxygen to H_2O_2(O2/H_2O_2 at 0.69 V versus RHE). The positive shift of valence band also improves hole collection and leads to enhanced formation of H_2O_2. | Ruirui Wang Xin Zhang Fan Li Ding Cao Min Pu Dandan Han Junjiao Yang Xu Xiang | 2018 | Journal of Energy Chemistry2018，27，2： | 4 |
| 3 | The effect of biomass pyrolysis gas reburning on N_2O emission in a coal-fired fluidized bed boiler显示文摘The fossil fuel consumption and pollutant emissions in a coal fired fluidized bed boiler could be reduced by biomass pyrolysis gas reburning.The influence of three kinds of biomass pyrolysis gases on the emission of N_2O in a laboratory scale fluidized bed was investigated using the mechanism of GRI3.0 in this paper.The results showed that:the effect of sawdust pyrolysis gas reburning on N_2O was more significant than that of rice husk and orange peel under the same conditions;the increase of initial oxygen content from 1% to 8% in flue gas would restrain the decomposition of N_2O;the N_2O decomposition was enhanced by increasing reaction temperature from 1073.15 K to 1323.15 K,and the decomposition rate may reach 99% at 1223.15 K. | HU XiaoYing DONG ChangQing YANG YongPing ZHANG JunJiao | 2011 | Chinese Science Bulletin2011，56，14： | 2 |

| 6 | Synthesis, characterization, crystal structure and antitumor activities of a novel demethylcantharidato bridged copper(Ⅱ) phenanthroline complex显示文摘A new polymeric demethylcantharidato (DCA) bridged copper(Ⅱ) phenanthroline (phen) complex ([Cu(DCA)(phen)] n ·nH2O) has been synthesized and characterized by elemental analysis, IR and electronic spectra studies, molar conductivity measurement, and single crystal X-ray diffraction. The complex crystallizes in the orthorhombic space group Pbca with crystallographic data: a = 12.4537(4), b = 9.3897(5), c = 30.1264(10), and Z = 8. In the crystal structure, the octahedral coordinated copper(Ⅱ) ions are bridged by demethylcantharidate ligands into a one-dimensional zigzag-like structure with the Cu···Cu separation of 6.1719, along with phen ligands attached to both sides of the chain alternatively. Interdigitation of the chelating phen ligands of two neighboring chains via hydrophobic interaction and van der Waals forces along ac plane forms two-dimensional polymeric bilayers with discrete water sandwich layer between the adjacent polymeric bilayers. The evaluation of the cytotoxic activity of the copper(Ⅱ) complex against HCT-8 (colorectal carcinoma), A549 (pulmonary carcinoma), HeLa (cervical cancer), HepG2 (hepatocarcinoma), BGC-823 (gastric carcinoma), and MCF-7 (breast adenocarcinoma) cell lines revealed that it is a potent cytotoxic agent, superior to Na2DCA and phen against HeLa, HepG2 and BGC-823 cells. | YIN FuLing ZHU JingJing HAO Jian CUI JingRong YANG JunJiao | 2013 | Science China Chemistry2013，56，4： | 0 |
| 7 | Genetic Diversity and Genetic Structure of Maize Inbred Lines from Yunnan Revealed by SNP Chips显示文摘[Objectives]The genetic diversity and population genetic structure of 107 inbred lines of maize in Yunnan were analyzed,in order to provide technical support for maize germplasm innovation,genetic improvement of germplasm resources,variety management,and lay a solid foundation for exploring genes related to fine traits in the future.[Methods]The 107 maize inbred lines generalized in Yunnan were selected,and 45 backbone inbred lines commonly used in China were used as reference for heterotic group classification.On Axiom Maize 56K SNP Array platform,maize SNP chips(56K)were used to scan the whole maize genome,and the NJ-tree model of Treebest was used to construct a phylogenetic tree.Principal component analysis(PCA)was conducted by GCTA(genome-wide complex trait analysis)to reveal the genetic diversity and population genetic structure.[Results]In the 107 Yunnan local inbred lines,5533 uniformly distributed high-quality SNP marker sites were finally detected.Based on the analysis of these SNP marker sites,Nei s gene diversity index(H)of 107 maize germplasm genes was 0.2981-0.5000 with an average value being 0.4832,and polymorphism information content(PIC)values were 0.2536-0.3750 with an average value being 0.3662.The minimum allele frequency value was 0.5000-0.8178 with an average value being 0.5744.The analysis of population genetic structure showed that when K=6,the maximum value of△K was the maximum,which meant that the inbred lines used in this study could be divided into six groups.They were Tangsi Pingtou blood relationship group,PB blood relationship group,335 female blood relationship group,Zi 330 and the Lüda Honggu blood relationship group,unknown group 1 and unknown group 2.No inbred lines were divided into other heterotic groups.Among them,37 inbred lines from the 2 unknown groups could not be classified into the same group as the 10 known heterotic groups in China.The results of principal component analysis showed that the 107 maize inbred lines generalized in Yunnan could be clearly distinguished from the backbone maize inbred lines commonly used in China.Most of the maize inbred lines in Yunnan were concentrated near the reference backbone inbred lines.But some Yunnan inbred lines were far away from the reference inbred lines commonly used in China.[Conclusions]The maize germplasm resources in Yunnan area were rich in genetic diversity,including multiple heterotic groups,and there was a rich genetic basis of breeding parents.They could be clearly distinguished from the backbone inbred lines commonly used in China,and some of them had a long genetic distance from the backbone inbred lines.The resources which have good application potential can be used to create new heterotic groups. | Junjiao GUAN Peng ZHANG Sheping LI Junhao LU Qingmei HUANG Xiaohong YANG Jianhua ZHANG Zhuke KANG | 2021 | Agricultural Biotechnology2021，10，2： | 0 |
| 8 | Synthesis and ultraviolet/aggregation-induced emission investigation of novel tetraphenylvinyl hydrazone derivatives: efficient multimodal chemosensors for fluoride ion显示文摘Herein,three novel tetraphenylethylene hydrazone chemosensors TC12,SC16,and TC16 are prepared for the selective detection of F−.Two NH and one C=N units are incorporated into the sensors for better colorimetric responses,whereas the tetraphenyl unit is in charge of the aggregation-induced emission effect.Among them,compounds SC16 and TC16 form stable gels with some organic solvents.All the tetrahydrofuran/H2O solutions of the three compounds exhibit aggregation-induced emission effect,whereby the fluorescence emission increases by varying degrees with the volume of poor solvent water.Moreover,good aggregation-induced emission effects are observed in the self-assembly of SC16 and TC16.As a sample chemosensor,TC12 in tetrahydrofuran responds to F−selectively with high sensitivity,with the colorimetric and fluorometric detection limits of 8.25×10^(−7) mol·L^(-1) and 2.69×10^(−7) mol·L^(-1),respectively.The reversible gel-sol-gel phase transition and color changes indicate that both SC16-dimethyl sulfoxide and TC16-ethyl acetate gels specifically respond to F-with good sensitivity.The detection results are well supported by ultraviolet-visible spectroscopy,fluorescent spectroscopy,and 1H nuclear magnetic resonance.More importantly,the driving forces of gelation are visually clarified through the single crystal X-ray analysis of compound TOMe. | Wenting Yin Linqi Shi Mengjiao Liang Yaodong Huang Junjiao Yang | 2023 | Frontiers of Chemical Science and Engineering2023，17，12： | 0 |
