| 2 | Rice OsRAD21-2 is Expressed in Actively Dividing Tissues and its Ectopic Expression in Yeast Results in Aberrant Cell Division and Growth显示文摘Rad21 and its meiotic counterpart Rec8,the key components of the cohesin complex,are essential for sister chromatid cohesion and chromosome segregation in mitosis and meiosis,respectively.In contrast to yeast and vertebrates,which have only two RAD21/REC8 genes,the rice genome encodes four Rad21/Rec8 proteins.Here,we report on the cloning and characterization of OsRAD21-2 from rice(Oryza sativa L.).Phylogenetic analysis of the full-length amino acids showed that OsRad21-2 was grouped into the plant-specific Rad21 subfamily.Semi-quantitative reverse transcription-polymerase chain reaction revealed OsRAD21-2 preferentially expressed in premeiotic owers.Further RNA in situ hybridization analysis and promoter:β-glucuronidase staining indicated that OsRAD21-2 was mainly expressed in actively dividing tissues including premeiotic stamen,stem intercalary meristem,leaf meristem,and root pericycle.Ectopic expression of OsRAD21-2 in fission yeast resulted in cell growth delay and morphological abnormality.Flow cytometric analysis revealed that the OsRAD21-2-expressed cells were arrested in G2 phase.Our results suggest that OsRad21-2 functions in regulation of cell division and growth. | Chunyan Gong Tang Li Qi Li Longfeng Yan Tai Wang | 2011 | Journal of Integrative Plant Biology2011，53，1： | 3 |
| 3 | Two New Wasps (Hymenoptera:Stephanoidea:Ephialtitidae) from the Middle Jurassic of China显示文摘Two new species of wasps belonging to the family Ephialtitidae,Praeproapocritus flexus sp.nov.and Proapocritus parallelus sp.nov.,from the Middle Jurassic Jiulongshan Formation of southeastern Inner Mongolia,China,are described and illustrated.Praeproapocritus vulgates Rasnitsyn&Zhang,2010 and six species of Proapocritus,P.densipediculus,P.sculptus,P.longantennatus,P.formosus,P.atropus,and P.elegans,all described by Rasnitsyn and Zhang in 2010,are first record from the Middle Jurassic of China.These two new findings supplement the morphological understanding of ephialtitids in the Middle Jurassic of China and broaden the diversity of ephialtitids in their by-gone ecosystems. | LI Longfeng SHIH Chungkun REN Dong | 2013 | Acta Geologica Sinica(English Edition)2013，87，6： | 3 |

| 5 | A new phosphidation route for the synthesis of NiPx and their cocatalytic performances for photocatalytic hydrogen evolution over g-C3N4显示文摘Ni-based phosphides(NiPx)composed of earth-abundant elements are promising cocatalysts to replace noble metals for photocatalytic H2 evolution reaction(HER).A safe,energy-saving,and compositioncontrollable synthesis of NiPx is still highly desired.A facile and mild solvothermal process was developed for the first time for selective synthesis of a series of NiPx,including Ni,Ni12P5,Ni2P/Ni12P5,Ni/Ni2P and Ni2P,through controlling the dosage of NaBH4 and NaH2PO2.The phosphidation process was mainly composed of(1)a sequential reduction of Ni2+to Nj0 and(H2PO2)-to P(around the formed Ni0)triggered by NaBH4,and(2)a final phosphidation between Nj0 and the in situ generated P atoms.The photocatalytic HER performance of g-C3N4 can be substantially improved with the decoration of NiPx(3 wt%)as the separation of photoinduced charge carriers can be promoted and some active sites with low over-potential for HER can be introduced.The cocatalytic efficiency of NiPx is mainly determined by P content.Ni2P with a high ratio of P consequently exhibits the highest HER performance(215.1 umol g-1 h-1),which is almost six times higher than that of the pristine g-C3N4(35.6 umol g-1 h-1).Thus,as for the cocatalyst based on Ni phosphides,Ni2P is the preferable crystal phase and more efforts should be devoted to Ni2P to further optimize its structure,texture,and morphology in future works. | Ziqun Wang Longfeng Li Mingzhu Liu Tifang Miao Xiangju Ye Sugang Meng Shifu Chen Xianliang Fu | 2020 | Journal of Energy Chemistry2020，29，9： | 2 |
| 6 | Performance-enhanced and cost-effective triboelectric nanogenerator based on stretchable electrode for wearable SpO2 monitoring显示文摘Recently,stretchable and wearable health monitoring equipment has greatly improved human’s daily life,which sets higher demands for portable power source in stretchability,sustainability,and biocompatibility.In this work,we proposed a stretchable triboelectric nanogenerator(TENG)based on stretchable poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS)/porous carbon hybrid for oxyhemoglobin saturation(SpO2)monitoring.To combine advantages of carbon material for its high conductivity and organic electrode for its high stretchability,we spin-coated a solution of PEDOT:PSS/porous carbon onto a plasma-treated pre-stretched Ecoflex film to fabricate a stretchable electrode with rough surface.Due to its roughness and high potential difference with the dielectric material,the stretchable-electrode-based TENG exhibited better performance compared to the pristine TENG based on carbon or PEDOT:PSS material.The output voltage and current reached up to 51.5 V and 13.2μA as the carbon concentration increased.More importantly,the performance further increased under large strain(100%)which is suitable for wearable systems.Finally,the device demonstrated its application potential for powering a flexible blood oxygen monitor.This simple and cost-effective method can enhance the stretchability and stability of organic/inorganic electrode-based TENG,which paves the development of high-performance stretchable TENG. | Huamin Chen Wei Yang Cheng Zhang Mingqiang Wu Wenjie Li Yuxiao Zou Longfeng Lv Hualiang Yu Huizhen Ke Ruping Liu Yun Xu Jun Wang Zhou Li | 2022 | Nano Research2022，15，3： | 2 |

| 10 | Research on Characters of Leaf Epidermal Cells' Quantities of Solanaceous Vegetable Crops显示文摘Tomatoes,peppers and eggplants' seedings were used as experiment materials to study the leaf development mechanism of solanaceous vegetable crops by using blot observation method.Results showed that an increasing trend was presented at the density of cells and stomata in upper and lower epidermis,but a declined trend was presented at the cells' diameters and the size of stomata with the joint position rising.At the same joint position,no matter in adaxial side or abaxial side,there were some differences among cells diameters,size of stomata,density of cells and stomata. | YU Longfeng AN Fuquan GAO Jinhe LI Fuheng | 2010 | Journal of Northeast Agricultural University(English Edition)2010，17，3： | 0 |
| 11 | Study on Quantitative Character for Anatomy in Tomato Seedling Stem显示文摘The results of quantitative characters for anatomy in stems of three varieties tomatoes seedlings showed that the cell population between vascular bundle and epidermis, the cellular layers among vascular bundles and the cell population in an unit area (mm2) of no vascular bundle areas were similar and there had small difference among three varieties. On the foundation of these studies, the developmental mechanism of tomato seedling stem was discussed. | LI Fuheng WEI Liyan YU Longfeng QI Donglai ZHANG Da | 2009 | Journal of Northeast Agricultural University(English Edition)2009，16，1： | 0 |
