| 1 | Rhizobacterium Bacillus amyloliquefaciens Strain SQRT3-Mediated Induced Systemic Resistance Controls Bacterial Wilt of Tomato显示文摘Tomato bacterial wilt caused by Ralstonia solanacearum seriously threats tomato growth in tropical and temperate regions around the world.This study reported an antagonistic bacterial strain, Bacillus amyloliquefaciens strain SQRT3, isolated from the rhizosphere soil of tomato plants, which strongly inhibited in vitro growth of pathogenic R.solanacearum.The suppression of tomato bacterial wilt by strain SQRT3 was demonstrated under greenhouse conditions.Additionally, induced systemic resistance(ISR) in tomato as one of the potential disease suppression mechanisms was investigated in the plants inoculated with the isolated bacterial strain SQRT3.The results showed that strain SQRT3 applied with R.solanacearum by drenching significantly reduced tomato bacterial wilt by 68.1% biocontrol efficiency(BE) and suppressed the R.solanacearum populations in the rhizosphere soil compared to the control only drenched with R.solanacearum.The BE of the isolated bacterial strain SQRT3 against tomato wilt increased to 84.1%by root-dipping.Tomato plants treated with both strain SQRT3 and R.solanacearum showed increases in activities of peroxidase and polyphenol oxidase compared with other treatments.The application of strain SQRT3 reduced membrane lipid peroxidation in tomato leaves.The expressions of marker genes for jasmonic acid-and salicylic acid-dependent signaling pathways were faster and stronger in tomato plants treated with both strain SQRT3 and R.solanacearum than in plants treated with either R.solanacearum or strain SQRT3 alone.Collectively, the findings indicated that strain SQRT3 can effectively control tomato wilt. | LI Chunyu HU Weicong PAN Bin LIU Yan YUAN Saifei DING Yuanyuan LI Rong ZHENG Xinyan SHEN Biao SHEN Qirong | 2017 | Pedosphere2017，27，6： | 18 |
| 2 | Highly efficient photocatalytic reduction of nitrogen into ammonia by single Ru atom catalyst supported by BeO monolayer显示文摘Ammonia(NH_(3))is one of the most important building blocks of the chemical industry and a promising sustainable energy carrier.Conventional production of NH_(3)via the Haber-Bosch process requires high temperature and high pressure,which is energy demanding and suffers safety issues.Photocatalytic nitrogen reduction reaction(NRR)is a green and sustainable route for NH_(3) production,and has been expected to be an alternative for NH_(3)production under mild conditions.However,solar-driven N_(2)activated has appeared as the bottleneck for photocatalytic NRR.In this work,we propose that single Ru atom supported by BeO monolayer is a promising photocatalytic single atom catalyst(SAC)for efficient N_(2)activation with visible illumination.The high efficiency originates from the enhanced absorption in the visible range,as well as the back-donation mechanism when N_(2)were adsorbed on the SAC.Our results show that N_(2)can be efficiently activated by the Ru/BeO SAC and be reduced to NH_(3) with extremely low limiting potential of-0.41 V.The NRR process also exhibits dominate selectivity respect to hydrogen evolution. | Saifei Yuan Beixi Xu Shujuan Li Wenbiao Zhu Shulai Lei Wenyue Guo Hao Ren | 2022 | Chinese Chemical Letters2022，33，1： | 0 |
