Entwicklungsgeschichte und Ultrastruktur von Pollenkitt und Exine bei nahe verwandten entomophilen und anemophilen Angiospermensippen derAlismataceae,Liliaceae, Juncaceae,Cyperaceae, Poaceae undAraceae

Some closely related members of the monocotyledonous familiesAlismataceae, Liliaceae, Juncaceae, Cyperaceae, Poaceae andAraceae with variable modes of pollination (insect- and wind-pollination) were studied in relation to the ultrastructure of pollenkitt and exine (amount, consistency and distribution of pollenkitt on the surface of pollen grains). The character syndromes of pollen cementing in entomophilous, anemophilous and intermediate (ambophilous or amphiphilous) monocotyledons are the same in principal as in dicotyledons. Comparing present with former results one can summarize: 1) The pollenkitt is always produced in the same manner by the anther tapetum in all angiosperm sub-classes. 2) The variable stickiness of entomophilous and anemophilous pollen always depends on the particular distribution and consistency of the pollenkitt, but not its amount on the pollen surface. 3) The mostly dry and powdery pollen of anemophilous plants always contains a variable amount of inactive pollenkitt in its exine cavities. 4) A step-by step change of the pollen cementing syndrome can be observed from entomophily towards anemophily. 5) From the omnipresence of pollenkitt in all wind-pollinated angiosperms studied one can conclude that the ancestors of anemophilous angiosperms probably have been zoophilous (i.e. entomophilous) throughout.

     

Identification and Characterization of the First Equine Parainfluenza Virus 5

正Dear Editor,Parainfluenza virus 5 (PIV5), known as canine parainfluenza virus in the veterinary field, is a negative-sense,nonsegmented, single-stranded RNA virus belonging to the Paramyxoviridae family (Chen 2018). The virus was first reported in primary monkey kidney cells in 1954 (Hsiung1972), then it has been frequently discovered in various     

动物病毒学的成就及展望

1我国动物病毒学领域50年的主要成就及相关科学家的贡献 动物病毒学是一门综合性学科,它是建立在生物化学、生物物理学、分子生物学、分子遗传学和生物高新技术等相关学科基础上,其中任一学科的每一次突破,都将带动动物病毒学的飞速发展.80年代以来,生物技术的出现和发展,先后创制了几十种疫苗,通过对免疫预防、诊断技术的系统研究,取得了前所未有的成果.近些年来,人们在病毒特性的研究方面,尤其是在病毒本身基因组结构分析、病毒培养技术、病毒诊断技术、病毒分子流行病学调查以及生物工程疫苗研制等诸多方面,取得了前所未有的巨大成就,标志着动物病毒学已经进入了一个崭新的时代.     

病毒编码泛素及相关蛋白的研究进展

泛素(Ubiquitin, Ub)是一种由76个氨基酸残基组成的小分子蛋白,广泛存在于各种真核生物中,不同来源的泛素蛋白具有类似的结构、功能和免疫学特征.目前所知,泛素主要通过ATP依赖性的泛素-蛋白酶复合体通路(Ubiquitin-proteasomes pathway, UPP)途径,经泛素活化酶(E1)、泛素结合酶(E2)和泛素连接酶(E3)的梯级反应,高效并高度选择性地对胞质或胞核内蛋白进行完全或部分降解,泛素依赖性蛋白质降解涉及细胞周期调控、信号转导、DNA修复和蛋白质数量控制[1].另外,泛素还可作为分子伴侣参与核糖体的生物发生、DNA转录调控及其它多种生理功能[2].近年来发现,一些真核生物病毒,如杆状病毒、疱疹病毒、痘病毒、腺病毒和反转录病毒等,均编码泛素或能与泛素相互作用的蛋白.病毒编码的泛素和泛素相关蛋白与病毒粒子形成及病毒出芽增殖有关,也与宿主细胞凋亡调控、宿主免疫系统调控及病毒侵染宿主细胞的机理相联系.本文就这一方面的研究进展进行简述.     

Continued antigenic variation of highly pathogenic avian influenza A (H7N9) virus in laying hens in China, 2020–2021

Highlights
1. 13 strains of H7N9 viruses from laying hens in 2020 and 2021 were identified.
2. H7N9 viruses in China comprised at least 11 genotypes.
3. H7N9 viruses are high pathogenic in chickens, not in ducks.
4. The most H7N9 viruses cross-reacted poorly with H7-Re3 antiserum.
5. The H7-Re3 vaccine was unable to prevent H7N9 infection.     

Recombinant human interferon-α1b inhibits SARS-CoV-2 better than interferon-α2b in vitro

Highlights
1) A comprehensive evaluation method for anti-SARS-CoV-2 drugs was established based on RT-qPCR, TCID₅₀ method, and immunofluorescence.
2) A significant antiviral effect of rHuIFN-α1b was shown with EC₅₀=0.12 IU/mL in Vero cells and EC₅₀=0.52 IU/mL in Calu-3 cells, which was better than rHuIFN-α2b (EC₅₀=0.25 IU/mL in Vero cells and EC₅₀=2.48 IU/mL in Calu-3 cells).
3) rHuIFN-α1b has a good potential in the application of anti-COVID-19 therapy.
