一些抗植物病毒剂对烟草花叶病毒衣壳蛋白体外聚合过程的影响

Influence of Some Antiphytovlral Substances on the Polymerization(in vitro)of Coat Protein of Tobacco Mosaic Virus(TMV)

一些抗植物病毒剂对烟草花叶病毒衣壳蛋白体外聚合过程的影响江山，郭雪柳，韩熹莱（北京农业大学基础科技学院，北京１０００９４）关键词抗植物病毒剂，烟草花叶病毒，病毒衣壳蛋白，体外聚合研究表明，有些植物病毒的核酸对寄主植物的侵染活性只有装配完整的病毒颗粒的...

he influence of six antiphytoviral substances,including three base analogues and threemembrane lipid analogues,on the polymerization of coat protein of tobacco mosaic virus(TMV)was studied under different temperatures in vitro.The results demonstrated that all of the testedantiphytoviral substances can restrain the polymerization of TMV coat protein,The base ana-logues,including DHT,DH-DHT and Virazole,showed suppression to the polymerization processmuch more than lipid analogues, NS-83 and soybean lecithin.All the inhibition to the polymer-ization of TMV coat protein were taken place above 22℃except E-30′s.The E-30 have remark-ably inhibited the TMV coat protein polymerization.These actions suggested that all of tested an-tiphytoviral substances would be contributed to pressure the process of virion assembly.
