根据迄今为止的资料,植物病毒不含有任何酶系统,它是利用寄主细胞内的原料、能量,甚至酶系统来繁殖的,这就会引起寄主代谢控制的失调,造成病态。因此,寄主的新陈代谢和病毒的侵染增殖之间存在着极其密切的关系。了解这一关系不但为阐明病毒增殖的机制,及其对寄主的致病作用所必需,同时还可能为毒病的治疗研究提供依据。目前所以缺乏治疗毒病的有效药剂,其重要原因之一就是由于病毒和寄主间的关系太密切了。对病毒有效的药物,往往对寄主产生很大的药害,因此,寻求二者在代谢上的差异 According to the information so far, the plant virus does not contain any enzyme system, it is the use of host cells in raw materials, energy, and even the enzyme system to reproduce, which will lead to host metabolic control disorders, resulting in pathological. Therefore, there is an extremely close relationship between host metabolism and viral infection and proliferation. Understanding this relationship is not only necessary to elucidate the mechanism of virus proliferation and its role in the pathogenesis of the host, but may also provide a basis for the study of the treatment of toxins. At present, one of the important reasons for the lack of an effective agent for the treatment of toxic diseases is that the relationship between the virus and the host is too close. Drugs that are effective against viruses often have a large phytotoxicity to the host, and therefore, seek a metabolic difference between the two
