Virus diseases of perennial trees and vines have characteristics not amenable to study using small model annual plants. Unique disease symptoms such as graft incompatibilities and stem pitting cause considerable crop losses. Also, viruses in these long-living plants tend to accumulate complex populations of viruses and strains. Considerable progress has been made in understanding the biology and genetics of Citrus tristeza virus (CTV) and in developing it into a tool for crop protection and improvement. The diseases in tree and vine crops have commonalities for which CTV can be used to develop a baseline. The purpose of this review is to provide a necessary background of systems and reagents developed for CTV that can be used for continued progress in this area and to point out the value of the CTV-citrus system in answering important questions on plant-virus interactions and developing new methods for controlling plant diseases.
多年生树木和藤本植物的病毒病具有不易用小型模式一年生植物进行研究的特点。独特的病症,如嫁接不亲和和茎凹陷,导致相当大的作物损失。此外,这些长寿植物中的病毒往往会积累复杂的病毒和菌株群体。人们在理解柑橘衰退病毒(CTV)的生物学和遗传学方面取得了相当大的进展,并将其开发成一种用于作物保护和改良的工具。树木和藤本作物的病害有一些共同之处,可以利用 CTV 为其建立一个基准。本综述的目的是提供为 CTV 开发的系统和试剂的必要背景,以便在该领域继续取得进展,并指出 CTV-柑橘系统在回答有关植物-病毒相互作用的重要问题和开发控制植物病害的新方法方面的价值。
