| 1 | Systematic Analysis of Gene Expression in Western Flower Thrip( Frankliniella occidentalis Pergande ) before and after Infection with Impatiens Necrotic Spot Virus(INSV)显示文摘Impatiens necrotic spot virus( INSV) is an important plant virus identified in recent years. Western flower thrip( Frankliniella occidentalis) has been confirmed to be the most efficient vector for INSV. In the present study,Illumina's second-generation sequencing technique was used to determine the variation in gene expression at the transcriptome level in western flower thrip before and after infection with INSV. By aligning 168 188 unigenes of western flower thrip to the NCBI protein database,47 558 unigenes were annotated,accounting for 28. 27% of the total. Species classification revealed that 58. 7% of the annotated unigenes of western flower thrip did not match any other species,and 15. 4% of had a match in Zootermopsis navadensis,12. 4% in Mus musculus,7. 3% in Mustela putorius,3. 4% in Theileria parva,and 2. 7% in Tribolium castaneum. By analyzing DEGs between INSV-free and INSV-carrying western flower thrips,we found that 11 genes were upregulated,and 9 genes were downregulated in western flower thrip after INSV infection. In addition,cell cycle and ubiquitin-proteasome pathway in western flower thrip were significantly infected by INSV infection. | Jiani LIU Shengguang XU Yuyu ZHANG Zebin CHEN Rong LU Lei YU | 2017 | Agricultural Biotechnology2017，6，5： | 1 |
| 2 | Combinatorial Optimization of Physics Parameterization Schemes for Typhoon Simulation Based on a Simple Genetic Algorithm(SGA)显示文摘Each physical process in a numerical weather prediction(NWP)system may have many different parameterization schemes.Early studies have shown that the performance of different physical parameterization schemes varies with the weather situation to be simulated.Thus,it is necessary to select a suitable combination of physical parameterization schemes according to the variation of weather systems.However,it is rather difficult to identify an optimal combination among millions of possible parameterization scheme combinations.This study applied a simple genetic algorithm(SGA)to optimizing the combination of parameterization schemes in NWP models for typhoon forecasting.The feasibility of SGA was verified with the simulation of Typhoon Mujigae(2015)by using the Weather Research and Forecasting(WRF)model and Typhoon Higos(2020)by using the Coupled Ocean–Atmosphere–Wave–Sediment Transport(COAWST)modeling system.The results show that SGA can efficiently obtain the optimal combination of schemes.For Typhoon Mujigae(2015),the optimal combination can be found from the 1,304,576 possible combinations by running only 488 trials.Similar results can be obtained for Typhoon Higos(2020).Compared to the default combination proposed by the COAWST model system,the optimal combination scheme significantly improves the simulation of typhoon track and intensity.This study provides a feasible way to search for the optimal combinations of physical parameterization schemes in WRF and COAWST for more accurate typhoon simulation.This can help provide references for future development of NWP models,and for analyzing the coordination and adaptability of different physical process parameterization schemes under specific weather backgrounds. | Zebin LU Jianjun XU Zhiqiang CHEN Jinyi YANG Jeremy Cheuk-Hin LEUNG Daosheng XU Banglin ZHANG | 2024 | Journal of Meteorological Research2024，38，1： | 0 |
| 3 | Diversity of Moth Community in Wujiatang Wetland Park of Dianchi Lake显示文摘[Objective] The paper was to explore the species and dynamics of moths in Wujiatang wetland park in Dianchi lake. [Method] Moths under lamps in Wujiatang wetland park were investigated and studied regularly in 2016 and 2017, and the relationship among diversity index, indi-vidual number, species richness, evenness and diversity of moth community was analyzed. [Result] A total of 138 species of months belonging to 91 genera and 13 families were collected from Wujiatang wetland park, Dianchi lake, Kunming. The dominant insects were Crambidae and Noctuidae.The relationship between species and abundance relationship of moth community conformed to the niche priority occupation model, and the diversity index was not consistent with the evenness, but consistent with the species richness. [Conclusion]The study indicated that there were less species of moths in Wujiatang wetland park, and the community was unstable. | Liu Jiani Lu Rong Yang Yongyan Zhang Yuyu Chen Zebin Xu Shengguang Yu Lei | 2018 | Plant Diseases and Pests2018，9，3： | 0 |
