病毒是在宿主细胞内复制的亚细胞寄生虫，没有中间膜将宿主和病毒基因产物彼此隔离（船体，2002）。这种关系的高度密切性表明，病毒必须通过其繁殖的各种宿主细胞类型中发生的生化和生理过程将显著影响感染的结果。在植物中，宿主代谢的剧烈改变和重定向在许多关于不相容和相容的宿主-病毒相互作用的研究中已经观察到。然而，植物代谢的这些变化是否会影响植物对病毒感染的抵抗力或易感性？这个问题的答案很重要，原因有很多。首先，它将导致更好地了解植物-病毒相互作用。其次，它可以揭示诱导抗性现象的机制。最后，它可能使我们能够确定新的人工方法诱导植物病毒抗性的目标。
Viruses are subcellular parasites that replicate within a host cell with no intervening membrane to insulate host and viral gene products from each other (Hull, 2002). The highly intimate nature of this relationship suggests that the biochemical and physiological processes occurring in the various host cell types through which a virus must propagate will significantly affect the outcome of the infection. In plants, drastic alterations in, and redirection of, host metabolism have been observed in many studies of both incompatible and compatible host-virus interactions. However, is it safe to suggest that these changes in plant metabolism influence whether a plant is resistant or susceptible to the virus infection? The answer to this question is important for a number of reasons. Firstly, it will lead to a better general understanding of the plant-virus interaction. Secondly, it may reveal mechanisms underlying induced resistance phenomena. Finally, it may allow us to identify targets for novel, artificial methods of inducing resistance to plant viruses.
