| 1 | Transcriptomic analyses identify albino-associated genes of a novel albino tea germplasm ‘Huabai 1’显示文摘Albinism in shoots of tea plants is a common phenotypic expression which gives the tea infusion a pleasant umami taste.A novel natural albino mutant tea germplasm containing high amino acids content was found and named as‘Huabai 1’.‘Huabai 1’has white jade tender shoots under low temperature and turns green with increased temperature.In order to understand the molecular mechanism of color change in leaf of‘Huabai 1’,transcriptome analysis was performed to identify albino-associated differentially expressed genes(DEGs).A total of 483 DEGs were identified from white shoots of‘Huabai 1’compared to its green shoots.There were 15 DEGs identified to be involved in phenylpropanoid biosynthesis,which account for the majority of characterized DEGs.The metabolites related to phenylpropanoid biosynthesis revealed similar expression pattern of DEGs.Furthermore,metabolic pathways such as ubiquonone,tyrosine,and flavonoid biosynthesis associated with phenylpropanoid biosynthesis could also contribute to the color change in‘Huabai 1’tender shoots.Protein–protein interaction analysis revealed a hub protein NEDD8(CSA009575)which interacted with many regulated genes in spliceosome,nitrogen metabolism,phenylpropanoid biosynthesis,and other pathways.In conclusion,the findings in this study indicate that the color change of‘Huabai 1’tender shoots is a combined effect of phenylpropanoid biosynthesis pathway and other metabolic pathways including flavonoid biosynthesis in tea plants.Chlorophyll biosynthesis-related genes LHCII and SGR may also play some roles in color change of‘Huabai 1’. | Qingping Ma Huan Li Zhongwei Zou Emmanuel Arkorful Qianru Lv Qiongqiong Zhou Xuan Chen Kang Sun Xinghui Li | 2018 | Horticulture Research2018，5，1： | 7 |
| 2 | A Level Set Immersed Boundary Method for Water Entry and Exit显示文摘The interaction between free surface flow and structure is investigated using a new level set immersed boundary method.The incorporation of an improved immersed boundary method with a free surface capture scheme implemented in a Navier-Stokes solver allows the interaction between fluid flow with free surface and moving body/bodies of almost arbitrary shape to be modelled.A new algorithm is proposed to locate exact forcing points near solid boundaries,which provides an accurate numerical solution.The discretized linear system of the Poisson pressure equation is solved using the Generalized Minimum Residual(GMRES)method with incomplete LU preconditioning.Uniform flow past a cylinder at Reynolds number Re=100 is modelled using the present model and results agree well with the experiment and numerical data in the literature.Water exit and entry of a cylinder at the prescribed velocity is also investigated.The predicted slamming coefficient is in good agreement with experimental data and previous numerical simulations using a ComFlow model.The vertical slamming force and pressure distribution for the free falling wedge is also studied by the present model and comparisons with available theoretical solutions and experimental data are made. | Yali Zhang Qingping Zou Deborah Greaves Dominic Reeve Alison Hunt-Raby David Graham Phil James Xin Lv | 2010 | Communications in Computational Physics2010，8，7： | 2 |
| 3 | Enhanced catalytic oxidation of dichloromethane by a surfactant-modified CeO_(2)@TiO_(2) core-shell nanostructured catalyst显示文摘Surfactant-modified CeO_(2)@TiO_(2) core-shell nanostructure catalysts were prepared by coprecipitation with the addition of sodium dodecyl sulfonate(SDS),and their catalytic oxidation of dichloromethane(DCM) was studied.A 90% DCM conversion efficiency is obtained at 300℃ with the CeO_(2)@TiO_(2)SDS catalyst,and its catalytic stability in the 55 h test period is better than that of Ce/TiO_(2) and CeO_(2)@TiO_(2).Based on the characterization of CeO_(2)@TiO_(2)SDS,the dispersion of active components is promoted due to the inhibition of crystal growth with the introduction of SDS.The improvement of surface acidity and redox capacity is beneficial to the enhancement of catalytic activity.The higher adsorbed oxygen content on the surface of the CeO_(2)@TiO_(2)SDS catalyst is responsible for the better catalytic stability.Generally,a novel method was developed to design catalytic oxidation catalysts for the treatment of chlorinated volatile organic compounds in future applications. | Mengjie Fan Qingping Zou Jining Liu Yingwen Chen Jianliang Zhu Shubao Shen | 2023 | Journal of Rare Earths2023，41，7： | 1 |

| 6 | Steering Against Wind: A New Network of NamiRNAs and Enhancers显示文摘Micro RNAs(miRNAs) are a class of endogenous non-coding RNAs with regulatory functions. Traditionally, miRNAs are thought to play a negative regulatory role in the cytoplasm by binding to the 30 UTR of target genes to degrade m RNA or inhibit translation. However, it remains a challenge to interpret the potential function of many miRNAs located in the nucleus.Recently, we reported a new type of miRNAs present in the nucleus, which can activate gene expression by binding to the enhancer, and named them nuclear activating miRNAs(NamiRNAs). The discovery of NamiRNAs showcases a complementary regulatory mechanism of mi RNA, demonstrating their differential roles in the nucleus and cytoplasm. Here, we reviewed miRNAs in nucleus to better understand the function of NamiRNAs in their interactions with the enhancers. Accordingly, we propose a Nami RNA–enhancer–target gene activation network model to better understand the crosstalk between NamiRNAs and enhancers in regulating gene transcription.Moreover, we hypothesize that NamiRNAs may be involved in cell identity or cell fate determination during development, although further study is needed to elucidate the underlying mechanisms in detail. | ying liang qingping zou wenqiang yu | 2017 | Genomics, Proteomics & Bioinformatics2017，15，5： | 1 |
| 7 | A Preconditioned Implicit Free-Surface Capture Scheme for Large Density Ratio on Tetrahedral Grids显示文摘We present a three dimensional preconditioned implicit free-surface capture scheme on tetrahedral grids.The current scheme improves our recently reported method[10]in several aspects.Specifically,we modified the original eigensystem by applying a preconditioning matrix so that the new eigensystem is virtually independent of density ratio,which is typically large for practical two-phase problems.Further,we replaced the explicit multi-stage Runge-Kutta method by a fully implicit Euler integration scheme for the Navier-Stokes(NS)solver and the Volume of Fluids(VOF)equation is now solved with a second order Crank-Nicolson implicit scheme to reduce the numerical diffusion effect.The preconditioned restarted GeneralizedMinimal RESidual method(GMRES)is then employed to solve the resulting linear system.The validation studies show that with these modifications,the method has improved stability and accuracy when dealing with large density ratio two-phase problems. | Xin Lv Qingping Zou D.E.Reeve Yong Zhao | 2012 | Communications in Computational Physics2012，11，1： | 0 |
| 8 | Effect of Na^(+)on catalytic performance of CoCe/ZSM-5 catalysts for oxidation of toluene显示文摘A CoCe/ZSM-5 catalyst was prepared by ultrasonic-assisted impregnation for the catalytic combustion of toluene.To study the effect of Na+on catalytic performance of CoCe/ZSM-5 catalysts,a series of different Si/Al ZSM-5 zeolites and catalysts doped with Na were synthesized.The experimental results show that 0.71 wt%Na+can inhibit active growth,generate more active small crystal grains,and promote improvement of the catalytic activity by the grain boundary segregation block mechanism,and the catalyst with 0.71 wt%of Na shows toluene conversion of 90 vol%at 250℃.Over 0.71 wt%of Na+content will neutralize the acid centre of the catalyst,lowering the specific surface area of the catalyst and resulting in a gradual decrease in the catalytic activity. | Qingping Zou Mingqing Liu Mengjie Fan Yaping Ding Yingwen Chen Shubao Shen | 2021 | Journal of Rare Earths2021，39，4： | 0 |
