| 1 | Xa7, a new executor R gene that confers durable and broad-spectrum resistance to bacterial blight disease in rice显示文摘Bacterial blight(BB)is a globally devastating rice disease caused by Xanthomonas oryzae pv.oryzae(Xoo).The use of disease resistance(R)genes in rice breeding is an effective and economical strategy for the control of this disease.Nevertheless,a majority of R genes lack durable resistance for long-term use under global warming conditions.Here,we report the isolation of a novel executor R gene,Xa7,that confers extremely durable,broad-spectrum,and heat-tolerant resistance to Xoo.The expression of Xa7 was induced by incompatible Xoo strains that secreted the transcription activator-like effector(TALE)AvrXa7 or PthXo3,which recognized effector binding elements(EBEs)in the Xa7 promoter.Furthermore,Xa7 induction was faster and stronger under high temperatures.Overexpression of Xa7 or co-transformation of Xa7 with avrXa7 triggered a hypersensitive response in plants.Constitutive expression of Xa7 activated a defense response in the absence of Xoo but inhibited the growth of transgenic rice plants.In addition,analysis of over 3000 rice varieties showed that the Xa7 locuswas found primarily in the indica and aus subgroups.A variation consisting of an 11-bp insertion and a base substitution(G to T)was found in EBEAvrXa7 in the tested varieties,resulting in a loss of Xa7 BB resistance.Through a decade of effort,we have identified an important BB resistance gene and characterized its distinctive interaction with Xoo strains;these findings will greatly facilitate research on the molecular mechanism of Xa7-mediated resistance and promote the use of this valuable gene in breeding. | Xifeng Chen Pengcheng Liu Le Mei Xiaoling He Long Chen Hui Liu Shurong Shen Zhandong Ji Xixi Zheng Yuchen Zhang Zhenyu Gao Dali Zeng Qian Qian Bojun Ma | 2021 | Plant Communications2021,2,3: | 9 |
| 2 | Synthesis of hexaaluminate catalysts for methane combustion by reverse microemulsion medium显示文摘The aim of this study is to synthesize the catalysts of Fe-and Mn-substituted hexaaluminate by reverse microemulsion medium for methane catalytic combustion application.Pseudo-ternary phase diagrams in quaternary microemulsion systems of cetyltrimethylammonium bromide(CTAB),n-butanol,n-octane,and water [or Al(NO3)3 solution] were presented.The effects of the alcohol chain length,ratio of sur-factant to cosurfactant,and salt concentration on the formation and stability of microemulsion systems were studied.The phase behavior of microemulsion systems was confirmed through the varying of the conductivity with the water content.The performance and structure of the catalysts,La(Mnx/Fex)Al12-x-O19-δ synthesized with the optimal parameter in the phase diagrams of microemulsions systems were characterized by BET,TG-DTA,and XRD.The micro fix-bed reactor was used to measure the catalytic activities of catalysts to methane combustion.The results showed that this synthesis method could yield non-agglomerated and highly dispersed precursors that would undergo crystallization at the lower temperature of 950℃.When temperature was raised up to 1050℃,the complete crystalline La-hexaaluminate was shaped.The hexaaluminate substituted with Fe had high-catalytic activity and stability at high temperature,while the Mn-substituted had higher catalytic activity at lower temperature.When the cooperation of Fe and Mn occurred,i.e.,LaFeMnAl10O19-δ exhibited a high surface area and catalytic activity to CH4 combustion,the CH4 light-off temperature was only 475℃ and the complete combustion temperature was 660℃.This was attributed to the synergistic effect between Fe and Mn. | BAI ShouLi WANG LiangShi SHI BingJie YANG PengCheng CUI MeiSheng LONG ZhiQi LI DianQing CHEN AiFan | 2009 | Science China Chemistry2009,52,1: | 6 |
| 3 | Au-Ag alloy nanoparticles with tunable cavity for plasmon-enhanced photocatalytic H2 evolution显示文摘Au-Ag alloy nanoparticles with different cavity sizes have great potential for improving photocatalytic performance due to their tunable plasmon effect.In this study,galvanic replacement was combined with co-reduction with the reaction kinetics processes regulated to rapidly synthesize Au-Ag hollow alloy nanoparticles with tunable cavity sizes.The position of the localized surface plasmon resonance(LSPR)peak could be effectively adjusted between 490 nm and 713 nm by decreasing the cavity size of the Au-Ag hollow nanoparticles from 35 nm to 20 nm.The plasmon-enhanced photocatalytic H2 evolution of alloy nanoparticles with different cavity sizes was investigated.Compared with pure P25(TiO2),intact and thin-shelled Au-Ag hollow nanoparticles(HNPs)-supported photocatalyst exhibited an increase in the photocatalytic H2 evolution rate from 0.48μmol h^−1 to 4μmol h^−1 under full-spectrum irradiation.This improved photocatalytic performance was likely due to the plasmon-induced electromagnetic field effect,which caused strong photogenerated charge separation,rather than the generation of hot electrons. | Xuanyu Yue Juan Hou Haifeng Zhao Pengcheng Wu Yali Guo Qin Shi Long Chen Shanglong Peng Zhiyong Liu Guozhong Cao | 2020 | Journal of Energy Chemistry2020,29,10: | 4 |
| 4 | Compositional dependence of hydrogenation performance of Ti-Zr-Hf-Mo-Nb high-entropy alloys for hydrogen/tritium storage显示文摘A series of Ti-Zr-Hf-Mo-Nb high-entropy alloys with different Mo concentrations were developed as candidate materials for hydrogen/tritium storage in solid phase.The crystal structures and hydrogenation properties of the Ti-Zr-Hf-Mo-Nb alloys were investigated by X-ray diffraction and differential scanning calorimetry techniques.All the alloys have a body-centred cubic single phase structure.The results demonstrate that the cell volume of the Ti-Zr-Hf-Mo-Nb hydride decreases with increasing Mo concentration,which reduces their thermal stability.The theoretical calculation proposes that the lower binding energy of the Ti-Zr-Hf-Mo-Nb hydride decreases the thermal stability of Ti-Zr-Hf-Mo-Nb alloys with higher Mo content.The great hydrogenation performance for all the Ti-Zr-Hf-Mo-Nb alloys is owing to their reversible single-phase transformation during the hydrogen absorption-desorption cycle,which would be bene ficial to improving the hydrogen recycling rate and preventing the disproportionation.The compositional dependence of the hydrogenation performance of the Ti-Zr-Hf-Mo-Nb alloys was established and will be useful in designing novel hydrogen/tritium storage materials to satisfy the requirements of diffe rent application fields in hydrogen,solar thermal and nuclear energy. | Huahai Shen Jutao Hu Pengcheng Li Gang Huang Jianwei Zhang Jinchao Zhang Yiwu Mao Haiyan Xiao Xiaosong Zhou Xiaotao Zu Xinggui Long Shuming Peng | 2020 | Journal of Materials Science & Technology2020,52,20: | 2 |

| 11 | ZC4H2 stabilizes RNF220 to pattern ventral spinal cord through modulating Shh/Gli signaling显示文摘ZC4H2 encodes a C4H2 type zinc-finger nuclear factor,the mutation of which has been associated with disorders with various clinical phenotypes in human,including developmental delay,intellectual disability and dystonia.ZC4H2 has been suggested to regulate spinal cord patterning in zebrafish as a co-factor for RNF220,an ubiquitin E3 ligase involved in Gli signaling.Here we showed that ZC4H2 and RNF220 knockout animals phenocopy each other in spinal patterning in both mouse and zebrafish,with mispatterned progenitor and neuronal domains in the ventral spinal cord.We showed evidence that ZC4H2 is required for the stability of RNF220 and also proper Gli ubiquitination and signaling in vivo.Our data provides new insights into the possible etiology of the neurodevelopmental impairments observed in ZC4H2-associated syndromes. | Pengcheng Ma Ning-Ning Song Xiaoning Cheng Liang Zhu Qiong Zhang Long long Zhang Xiangcai Yang Huishan Wang Qinghua Kong Deli Shi Yu-Qiang Ding Bingyu Mao | 2020 | Journal of Molecular Cell Biology2020,12,5: | 1 |
