| 1 | Coinfection with influenza A virus enhances SARS-CoV-2 infectivity显示文摘The upcoming flu season in the Northern Hemisphere merging with the current COVID-19 pandemic raises a potentially severe threat to public health.Through experimental coinfection with influenza A virus(IAV)and either pseudotyped or live SARS-CoV-2 virus,we found that IAV preinfection significantly promoted the infectivity of SARS-CoV-2 in a broad range of cell types.Remarkably,in vivo,increased SARS-CoV-2 viral load and more severe lung damage were observed in mice coinfected with IAV.Moreover,such enhancement of SARS-CoV-2 infectivity was not observed with several other respiratory viruses,likely due to a unique feature of IAV to elevate ACE2 expression.This study illustrates that IAV has a unique ability to aggravate SARS-CoV-2 infection,and thus,prevention of IAV infection is of great significance during the COVID-19 pandemic. | Lei Bai Yongliang Zhao Jiazhen Dong Simeng Liang Ming Guo Xinjin Liu Xin Wang Zhixiang Huang Xiaoyi Sun Zhen Zhang Lianghui Dong Qianyun Liu Yucheng Zheng Danping Niu Min Xiang Kun Song Jiajie Ye Wenchao Zheng Zhidong Tang Mingliang Tang Yu Zhou Chao Shen Li Zhou Yu Chen Huan Yan Ke Lan Ke Xu | 2021 | Cell Research2021，31，4： | 16 |
| 2 | Characteristics of fungal community structure during the decomposition of mixed foliage litter from Pinus massoniana and broadleaved tree species in southwestern China显示文摘针叶树凋落物相当顽强且养分含量低,而阔叶凋落物通过增加可降解养分和促进微生物代谢来促进针叶凋落物的分解。马尾松(Pinus massoniana)凋落物和三个阔叶凋落物混合可能会增加真菌分解者的多样性和丰富性,并且会随着阔叶树种的数量和比例而有所差异。我们使用高通量测序技术分析了西南地区马尾松与香椿(Toona sinensis),香樟(Cinnamomum camphora)和檫木(Sassafras tzumu)凋落叶混合分解过程中的真菌群落组成和多样性,共设置35种实验处理。研究结果表明,与单一凋落叶相比,除马尾松+香椿,马尾松+檫木+香椿和马尾松+檫木+香樟组合中马尾松凋落叶占70%-80%以及马尾松+檫木+香樟+香椿组合中香椿凋落叶所占比例较小外,其余混合凋落叶均增加了真菌的多样性和丰富性。其中马尾松+香樟+香椿组合中的7:1:2的真菌多样性和丰富性显著高于其他处理。子囊菌门和担子菌门是最主要的优势门,曲霉属是最丰富的真菌群落属。一针一阔(6:4)和一针两阔(阔叶凋落叶占30%-40%)组合的凋落叶在整个分解过程中均表现出较强的协同作用,并且增加了可分解较难分解物质真菌菌群的相对丰度。可见马尾松+香樟+香椿组合中阔叶凋落物占30%-40%比例时增加了真菌的多样性,促进了针叶凋落物中难分解物质的分解。因此,香椿和香樟可能是构建马尾松混交林潜在的候选阔叶伴生树种。 | Yan Zhang Xun Li Danju Zhang Yu Qin Yang Zhou Simeng Song Jian Zhang | 2020 | Journal of Plant Ecology2020，13，5： | 1 |
