| 1 | Potential regulation of small RNAs on bacterial function activities in pig farm wastewater treatment plants显示文摘Small RNAs(sRNAs)are key players in the regulation of bacterial gene expression.However,the distribution and regulatory functions of sRNA in pig farm wastewater treatment plants(WWTPs)remains unknown.In this study,the wastewaters in anoxic and oxic tanks of the WWTPs were collected.The profiles of the community structure,mRNA expression,and sRNA expression of bacteria in pig farm wastewater were investigated using transcriptome sequencing and qPCR.This study demonstrated that there was a higher abundance of sRNA in the pig farm WWTPs and 52 sRNAs were detected.The sRNAs were mainly present in Proteobacteria and Firmicutes,including the potential human pathogenic bacteria(HPB)(Escherichia,Shigella,Bordetella and Morganella),crop pathogen(Pectobacterium)and denitrifying bacteria(Zobellella).And the sRNAs were involved in the bacterial functional activities such as translation,transcription,drug resistance,membrane transport and amino acid metabolism.In addition,most sRNAs had a higher abundance in anoxic tanks which contained a higher abundance of the genes associated with infectious diseases and drug resistance than that in oxic tanks.The results presented here show that in pig farm WWTPs,sRNA played an important role in bacterial function activities,especially the infectious diseases,drug resistance and denitrification,which can provide a new point of penetration for improving the pig farm WWTPs. | Yiwen Yang Sicheng Xing Sumin Li Yajing Niu Cheng Li Tuoxin Huang Xindi Liao | 2020 | Journal of Environmental Sciences2020，32，5： | 1 |
| 2 | Differentiation of Continental Subduction Mode:Numerical Modeling显示文摘The convergence of the multi-layered continental lithospheres with variable and complex thermal and rheological properties results in various modes of continental collision with distinct deformation behavior of the lithospheric mantle. Using high-resolution thermo-mechanical numerical models,we systematically investigated the effects of crustal rheological strength and the convergence rate on the continental subduction mode. The model results reveal three basic modes of continental subduction,including slab break-off,steep subduction and continental flat-slab subduction. Whether lithospheric mantle of the overriding plate retreats or not during convergence enables the division of the first two modes into two sub-types,which are dominated by the crustal rheological strength. The mode of slab break-off develops under the conditions of low/moderate rheological strength of the continental crust and low convergence rate. In contrast,continental flat-slab subduction favors the strong crust and the high convergence rate. Otherwise,continental steep subduction occurs. The numerical results provide further implications for Geodynamics conditions and physical processes of different modes of continental collision that occur in nature. | Tuoxin Yang Pengpeng Huangfu Yan Zhang | 2019 | Journal of Earth Science2019，30，4： | 0 |
