| 1 | Internet of Things to network smart devices for ecosystem monitoring显示文摘Smart, real-time, low-cost, and distributed ecosystem monitoring is essential for understanding and managing rapidly changing ecosystems. However, new techniques in the big data era have rarely been introduced into operational ecosystem monitoring, particularly for fragile ecosystems in remote areas.We introduce the Internet of Things(IoT) techniques to establish a prototype ecosystem monitoring system by developing innovative smart devices and using IoT technologies for ecosystem monitoring in isolated environments. The developed smart devices include four categories: large-scale and nonintrusive instruments to measure evapotranspiration and soil moisture, in situ observing systems for CO2 and d13 C associated with soil respiration, portable and distributed devices for monitoring vegetation variables, and Bi-CMOS cameras and pressure trigger sensors for terrestrial vertebrate monitoring. These new devices outperform conventional devices and are connected to each other via wireless communication networks. The breakthroughs in the ecosystem monitoring IoT include new data loggers and longdistance wireless sensor network technology that supports the rapid transmission of data from devices to wireless networks. The applicability of this ecosystem monitoring IoT is verified in three fragile ecosystems, including a karst rocky desertification area, the National Park for Amur Tigers, and the oasis-desert ecotone in China. By integrating these devices and technologies with an ecosystem monitoring information system, a seamless data acquisition, transmission, processing, and application IoT is created. The establishment of this ecosystem monitoring IoT will serve as a new paradigm for ecosystem monitoring and therefore provide a platform for ecosystem management and decision making in the era of big data. | Xin Li Ning Zhao Rui Jin Shaomin Liu Xiaomin Sun Xuefa Wen Dongxiu Wu Yan Zhou Jianwen Guo Shiping Chen Ziwei Xu Mingguo Ma Tianming Wang Yonghua Qu Xinwei Wang Fangming Wu Yuke Zhou | 2019 | Science Bulletin2019，64，17： | 10 |
| 2 | WSe2 2D p-type semiconductor-based electronic devices for information technology:Design,preparation,and applications显示文摘The pioneering exfoliation of monolayer tungsten diselenide has greatly inspired researchers toward semiconducting applications.WSe2 belongs to a family of transition-metal dichalcogenides.Similar to graphene,WSe2 and analogous dichalcogenides have layered structures with weak van der Waals interactions between two adjacent layers.First,the readers are presented with the fundamentals of WSe2,such as types,morphologies,and properties.Here,we report the characterization principles and practices such as microscopy,spectroscopy,and diffraction.Second,the methods for obtaining high-quality WSe2,such as exfoliation,hydrothermal and chemical vapor deposition,are briefly listed.With advantages of light weight,flexibility,and high quantum efficiency,2D materials may have a niche in optoelectronics as building blocks in p-n junctions.Therefore,we introduce a state-of-the-art demonstration of heterostructure devices employing the p-type WSe2 semiconductor.The device architectures include field-effect transistors,photodetectors,gas sensors,and photovoltaic solar cells.Due to its unique electronic,optical,and energy band properties,WSe2 has been increasingly investigated due to the conductivity of the p-type charge carrier upon palladium contact.Eventually,the dynamic research on WSe2 and van der Waals heterostructures is summarized to arouse the passion of the 2D research community. | Qilin Cheng Jinbo Pang Dehui Sun Jingang Wang Shu Zhang Fan Liu Yuke Chen Ruiqi Yang Na Liang Xiheng Lu Yanchen Ji Jian Wang Congcong Zhang Yuanhua Sang Hong Liu Weijia Zhou | 2020 | InfoMat2020，2，4： | 5 |
| 3 | Seryl tRNA synthetase cooperates with POT1 to regulate telomere length and cellular senescence显示文摘Deregulated telomere length is a causative factor in many physiological and pathological processes,including aging and cancer.Many studies focusing on telomeres have revealed important roles for cooperation between the Shelterin protein complex and telomerase in maintaining telomere length.However,it remains largely unknown whether and how aging-related stresses,such as deregulated protein homeostasis,impact telomere length.Here,we explored the possible roles of aminoacyl tRNA synthetases(AARSs),key enzymes catalyzing the first reactions in protein synthesis,in regulating telomere length and aging.We selected seryl tRNA synthetase(SerRS)since our previous studies discovered expanded functions of SerRS in the nucleus in addition to its canonical cytoplasmic role in protein synthesis.In this study,we revealed that overexpression of SerRS promoted cellular senescence and inhibited the growth of cervical tumor xenografts in mice by triggering the senescence of tumor cells.In the nucleus,SerRS directly bound to telomeric DNA repeats and tethered more POT1 proteins to telomeres through a direct interaction between the UNE-S domain of SerRS and the OB1 domain of POT1.We further demonstrated that SerRS-induced enrichment of POT1 prevented the recruitment of telomerase to telomeres,resulting in progressive telomere shortening.Our data suggested a possible molecular link between protein synthesis and telomere length control,the deregulation of which may be associated with aging and cancer. | Yingxi Li Xiyang Li Mei Cao Yuke Jiang Jie Yan Ze Liu Rongcun Yang Xu Chen Peiqing Sun Rong Xiang Longlong Wang Yi Shi | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 1 |

| 5 | Transcriptome Analysis and Genes Function Verification of Root Development of Paeonia suffruticosa under Sandy Loam Cultivation显示文摘Relatively poor in vitro rooting has limited the large-scale commercial production of tree peony.In this study,on the basis of transcriptome sequencing,differentially expressed genes and the associated metabolic pathways were identified in tree peony roots at different stages of root formation under sandy loam cultivation.A total of 31.63 Gb raw data were generated and 120,188 unigenes(mean length of 911.98 bp)were annotated according to six databases(NR,NT,GO,KEGG,COG,and Swiss-Prot).Analyses of the ungerminated root primordium period,induced root primordium period,and root formation period detected 8,232,6,907,and 10,687 differentially expressed genes related to 133,132,and 133 metabolic pathways,respectively.Two significantly differentially expressed genes(Unigene13430_All and CL10096.Contig1_All)were associated with the auxin pathway.The full-length Unigene13430_All coding sequence(843 bp)encoded 280 amino acids,whereas the full-length CL10096.Contig1_All coding sequence(1,470 bp)encoded 489 amino acids.Unigene13430_All and CL10096.Contig1_All were identified as IAA gene family members and were respectively named PsIAA27 and PsARF19.The qRT-PCR analysis and functional verification indicated that the expressions of PsARF19 and PsIAA27 in tree peony seedlings,cuttings and grafted seedlings were significant different.PsARF19 promoted root development,it might be a regulatory gene related to the formation of tree peony roots,while PsIAA27 inhibited lateral root development,and it might be involved in controlling auxin sensitivity during root formation.The results of this study may form the basis of future investigations on the mechanism mediating peony root formation.The transcriptome data will be an excellent resource for researchers interested in characterizing the rooting-related tree peony genes. | Yinglong Song Wenqian Shang Zheng Wang Songlin He Xinya Meng Liyun Shi Yuxiao Shen Dan He Xueyuan Lou Yuke Sun | 2022 | Phyton-International Journal of Experimental Botany2022，91，12： | 0 |
