| 1 | Characterization of Methylocystis strain JTA1 isolated from aged refuse and its tolerance to chloroform显示文摘To accelerate the efficiency of methane biodegradation in landfills,a Gram-negative,rod-shaped,non-motile,non-spore-forming bacterium,JTA1,which can utilize methane as well as acetate,was isolated from the Laogang MSW landfills,Shanghai,China.Strain JTA1 was a member of genus Methylocystis on the basis of 16S rRNA and pmoA gene sequence similarity.The maximum specific cell growth rates(μmax=0.042 hr-1,R2=0.995) was derived through Boltzmann simulation,and the apparent half-saturation constants(Km(app)=7.08mmol/L,R2=0.982) was calculated according to Michaelis-Menton hyperbolic model,indicating that Methylocystis strain JTA1 had higher-affinity potential for methane oxidation than other reported methanotrophs.By way of adding the strain JTA1 culture,the methane consumption of aged refuse reached 115mL,almost two times of control experiment.In addition,high tolerance of Methylocystis strain JTA1 to chloroform could facilitate the methane oxidation of aged refuse bio-covers.At the chloroform concentration of 50mg/L,the methane-oxidation rate of bio-cover reached 0.114mL/(day·g),much higher than the highest rate,0.0135mL/(day·g),of reported bio-covers.In conclusion,strain JTA1 opens up a new possibility for environmental biotechnology,such as soil or landfills bioremediation and wastewater decontamination. | Tiantao Zhao Lijie Zhang Yunru Zhang Zhilin Xing Xuya Peng | 2013 | Journal of Environmental Sciences2013，25，4： | 7 |
| 2 | Fast-Suppressor Screening for New Components in Protein Trafficking,Organelle Biogenesis and Silencing Pathway in Arabidopsis thaliana Using DEX-Inducible FREE1-RNAi Plants显示文摘Membrane trafficking is essential for plant growth and responses to external signals.The plant unique FYVE domain-containing protein FREE1 is a component of the ESCRT complex(endosomal sorting complex required for transport).FREE1 plays multiple roles in regulating protein trafficking and organelle biogenesis including the formation of intraluminal vesicles of multivesicular body(MVB),vacuolar protein transport and vacuole biogenesis,and autophagic degradation.FREE1 knockout plants show defective MVB formation,abnormal vacuolar transport,fragmented vacuoles,accumulated autophagosomes,and seedling lethality.To further uncover the underlying mechanisms of FREE1 function in plants,we performed a forward genetic screen for mutants that suppressed the seedling lethal phenotype of FREE1-RNAi transgenic plants.The obtained mutants are termed as suppressors of free1(sof).To date,229 putative sof mutants have been identified.Barely detecting of FREE1 protein with M3plants further identified 84 FREE1-related suppressors.Also145 mutants showing no reduction of FREE1 protein were termed as RNAi-related mutants.Through next-generation sequencing(NGS)of bulked DNA from F2mapping population of two RNAi-related sof mutants,FREE1-RNAi T-DNA inserted on chromosome 1 was identified and the causal mutation of putative sof mutant is being identified similarly.These FREE1-and RNAi-related sof mutants will be useful tools and resources for illustrating the underlying mechanisms of FREE1 function in intracellular trafficking and organelle biogenesis,as well as for uncovering the new components involved in the regulation of silencing pathways in plants. | Qiong Zhao Caiji Gao PoShing Lee Lin Liu Shaofang Li Tangjin Hu Jinbo Shen Shuying Pan Hao Ye Yunru Chen Wenhan Cao Yong Cui Peng Zeng Sheng Yu Yangbin Gao Liang Chen Beixin Mo Xin Liu Shi Xiao Yunde Zhao Silin Zhong Xuemei Chen Liwen Jiang | 2015 | Journal of Genetics and Genomics2015，42，6： | 4 |

| 4 | Single-dose AAV-based vaccine induces a high level of neutralizing antibodies against SARS-CoV-2 in rhesus macaques显示文摘Dear Editor,Coronavirus disease 2019(COVID-19)is a highly infectious respiratory disease that continues to pose a serious global public health emergency.The disease shows a high infection rate,long incubation period,and rapidly emerging variants,which have led to its rapid spread worldwide(Krammer 2020).Many vaccines have been developed for the control of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),the virus responsible for COVID-19,including vaccines based on messenger RNA(mRNA)(Polack et al.2020),viral vectors(Zhu et al.2020),recombinant proteins(Yang et al.2020),and inactivated SARS-CoV-2(Zhang et al.2021). | Dali Tong Mei Zhang Yunru Yang Han Xia Haiyang Tong Huajun Zhang Weihong Zeng Muziying Liu Yan Wu Huan Ma Xue Hu Weiyong Liu Yuan Cai Yanfeng Yao Yichuan Yao Kunpeng Liu Shifang Shan Yajuan Li Ge Gao Weiwei Guo Yun Peng Shaohong Chen Juhong Rao Jiaxuan Zhao Juan Min Qingjun Zhu Yanmin Zheng Lianxin Liu Chao Shan Kai Zhong Zilong Qiu Tengchuan Jin Sandra Chiu Zhiming Yuan Tian Xue | 2023 | Protein & Cell2023，14，1： | 0 |
| 5 | Sub-acute toxicity of licorice-sargassum extract in Sprague-Dawley rats:biochemical,histopathological,and pharmacokinetic studies显示文摘To the Editor:The'eighteen antagonistic medicaments,'an indispensable component of Oriental Pharmacology,states that sargassum and licorice should not be administered simultaneously.^([1])Researchers have reported that co-administration of licorice and sargassum exerted toxic effects on the heart,liver,and kidney of rats.^([2,3])However,the classic recipe'Hai-Zao-Yu-Hu-Tang,'(containing licorice and sargassum)is currently used,though the safety profile of this medication has not been clearly defined.Therefore. | Xinyue Jing Xian Meng Zhenhui Wu Yongfang Ding Yunru Peng Mingqing Shen Qing Wang | 2022 | Chinese Medical Journal2022，，7： | 0 |
