| 1 | WRKY33-mediated indolic glucosinolate metabolic pathway confers resistance against Alternaria brassicicola in Arabidopsis and Brassica crops显示文摘The tryptophan(Trp)-derived plant secondary metabolites,including camalexin,4-hydroxyindole-3-carbonylnitrile,and indolic glucosinolate(IGS),show broad-spectrum antifungal activity.However,the distinct regulations of these metabolic pathways among different plant species in response to fungus infection are rarely studied.In this study,our results revealed that WRKY33 directly regulates IGS biosynthesis,notably the production of 4-methoxyindole-3-ylmethyl glucosinolate(4MI3G),conferring resistance to Alternaria brassicicola,an important pathogen which causes black spot in Brassica crops.WRKY33 directly activates the expression of CYP81F2,IGMT1,and IGMT2 to drive sidechain modification of indole-3-ylmethyl glucosinolate(I3G)to 4MI3G,in both Arabidopsis and Chinese kale(Brassica oleracea var.alboglabra Bailey).However,Chinese kale showed a more severe symptom than Arabidopsis when infected by Alternaria brassicicola.Comparative analyses of the origin and evolution of Trp metabolism indicate that the loss of camalexin biosynthesis in Brassica crops during evolution might attenuate the resistance of crops to Alternaria brassicicola.As a result,the IGS metabolic pathway mediated by WRKY33 becomes essential for Chinese kale to deter Alternaria brassicicola.Our results highlight the differential regulation of Trp-derived camalexin and IGS biosynthetic pathways in plant immunity between Arabidopsis and Brassica crops. | Han Tao Huiying Miao Lili Chen Mengyu Wang Chuchu Xia Wei Zeng Bo Sun Fen Zhang Shuqun Zhang Chuanyou Li Qiaomei Wang | 2022 | Journal of Integrative Plant Biology2022，64，5： | 2 |
| 2 | Spermine increases bactericidal activity of silver-nanoparticles against clinical methicillin-resistant Staphylococcus aureus显示文摘Methicillin-resistant Staphylococcus aureus(MRSA) has emerged worldwide as a major multidrugresistant pathogen that causes notable morbidity and mortality. Fast emerging of MRSA prevalence requires special attention for strengthening the inventory of antimicrobial compounds. Silver nanoparticles(AgNPs) have been widely used to treat multi-drug resistant pathogens due to the unique antibacterial properties, meanwhile spermine has been proven to exert outstanding inhibition effect to S.aureus with not yet fully understood mechanisms. The aim of this study was to investigate the synergistic effect of AgNPs and spermine as well as to determine the antibacterial activity of their combination against MRSA strains. Several clinical MRSA isolates and ATCC BAA-1026 were used to determine minimum inhibitory concentration(MIC) and fractional inhibitory concentration indices(FICI) of AgNPs and spermine, and a synergistic effect was observed. This phenomenon was further confirmed by growth curve and time-killing assays, showed that spermine could be used as an adjuvant for AgNPs in the treatment of MRSA infections. | Chang Liu Han Shen Su Wang Xiaoli Cao Hongpan Xu Yanyan Xia Tingting Bai Yufeng Liu Lijun Peng Chuchu Li Zhirui Guo Zhiyang Li | 2018 | Chinese Chemical Letters2018，29，12： | 1 |

| 5 | Establishment of green graphite industry:Graphite from biomass and its various applications显示文摘Resource-and energy-efficient biomass exploitation for green graphite production is one of the most effective strategies for satisfying graphite demand while minimizing energy consumption and carbon emissions.This study investigated green graphite production from biomass waste and its applications to establish a green graphite industry.Biomass pyrolysis and catalytic graphitization of biochar were studied first to produce green graphite.The optimized green graphite exhibited a reversible capacity of 264 mA h/g and 97%capacity retention over 100 cycles in a half-cell.Green graphite electrodes with a resistivity lower than 5μΩm were fabricated by using organic fraction bio-oil as a green binder.Other green graphite applications,including printing,conductive printing,pencils,and refractories,were also achieved.The overall process of graphite anode and electrode synthesis from biomass waste and short-rotation energy crops was modeled.Approx.95 kg of battery graphite or 109 kg of metallurgical graphite electrodes can be produced per ton of biomass with low primary energy consumption and carbon footprint.Prominently,the modeling result and life cycle assessment demonstrated that,for the production of battery graphite from biomass waste,net-negative-CO_(2)emissions(−0.57 kg CO_(2)-eq/kg graphite powders)with net-negative-primary energy consumption(−28.31 MJ/kg graphite powders)was achieved. | Ziyi Shi Shule Wang Yanghao Jin Lingfeng Zhao Shiwei Chen Hanmin Yang Yuxiao Cui Rikard Svanberg Chuchu Tang Jianchun Jiang Weihong Yang PäGJösson Tong Han | 2023 | SusMat2023，3，3： | 0 |
