1Feeding of Riptortus pedestris on soybean plants, the primary cause of soybean staygreen syndrome in the Huang-Huai-Hai river basin显示文摘Staygreen syndrome or Zhengqing in soybean has recently become a major issue for Chinese growers in the Huang-Huai-Hai river basin.Although previous studies revealed that staygreen can be induced when pods/seeds are damaged, it is unknown whether virus infection or insect infestation causes staygreen.To determine whether viral infection causes staygreen, a survey of soybean staygreen incidence in the Huang-Huai-Hai river basin was conducted in 2016 and 2017.Diseased samples were collected and analyzed using DAS-ELISA for Soybean mosaic virus, Watermelon mosaic virus, Bean pod mottle virus, Cucumber mosaic virus, and Bean common mosaic virus.The survey showed that the severity of soybean staygreen syndrome was most prevalent in Beijing, Henan, Shaanxi, and some parts of Shandong provinces, with yield losses from 0 to nearly 100%, but only a small fraction of samples were positive for the tested viruses.A field cage experiment and an insecticide treatment field trial were conducted to determine the contribution of the bean bug, Riptortus pedestris, to staygreen incidence.The field cage experiment showed that R.pedestris treatment resulted in shorter plants, more empty pods, increased numbers of abnormal seeds, and decreased yields.The field experiment showed that there were fewer R.pedestris and less soybean staygreen incidence in fields treated with insecticide than in untreated control fields.Together, these results suggest that R.pedestris infestation rather than virus infection induces staygreen syndrome and that growers in this region can mitigate staygreen syndrome via bean bug control.Kai Li Xinxin Zhang Jianqiu Guo Hannah Penn Tingting Wu Lin Li Hong Jiang Lidan Chang Cunxiang Wu Tianfu Han 2019The Crop Journal2019,7,3:30
2新数据环境下的城市设计--Alan Penn教授访谈显示文摘如今,城市设计日益受到来自数据环境变化引起的挑战。这些变化主要体现在有关城市'大数据'的理论、城市数据资源、分析尺度、精度及方法的演变。虽然技术乐观主义正在获得广泛的认同,但是关于城市设计范式在新数据环境下可能的变化的讨论方兴未艾。本文通过与伦敦大学学院院长Alan Penn教授(建筑计算方向教授)的对谈,探讨在城市设计过程中应用城市'大数据'的理论与实践意义及其他相关的议题。alan penn 沈尧 孙唯 姚妍华 2016北京规划建设2016,,4:5
3Prokaryote phylogeny meets taxonomy: An exhaustive comparison of composition vector trees with systematic bacteriology显示文摘We perform an exhaustive, taxon by taxon, comparison of the branchings in the composition vector trees (CVTrees) inferred from 432 prokaryotic genomes available on 31 December 2006, with the bacte-riologists' taxonomy-primarily the latest online Outline of the Bergey's Manual of Systematic Bacteri-ology. The CVTree phylogeny agrees very well with the Bergey's taxonomy in majority of fine branchings and overall structures. At the same time most of the differences between the trees and the Manual have been known to biologists to some extent and may hint at taxonomic revisions. Instead of demonstrating the overwhelming agreement this paper puts emphasis on the biological implications of the differences.GAO Lei1,2, QI Ji1**, SUN JianDong2,3 & HAO BaiLin1,2,4 1 Institute of Theoretical Physics, Chinese Academy of Sciences, Beijing 100080, China 2 T-Life Research Center, Fudan University, Shanghai 200433, China 3 Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300, China 4 Santa Fe Institute, Santa Fe, NM87501, USA Center for Comparative Genomics and Bioinformatics, Penn State University, 310 Wartik Building, University Park, PA16802, USA 2007Science China(Life Sciences)2007,50,5:4
