植物病毒—新型的外源基因表达载体

Plant viruses-novel vectors for expressing foreign genes.

与利用转基因植物表达外源基因相比 ,植物病毒载体具有表达水平高、速度快、宿主广等优点 ,是一类新型的外源基因表达载体。本文就植物病毒表达载体的构建策略、应用状况和存在的问题进行了综述。

For expression of foreign genes in plant, expression with plant virus vector has many advantages, such as high expression level, short expression period and wider plant hosts, etc., as compared with using transgenic technology. Plant viruses have been considered as novel vectors for expressing foreign genes. In this paper, the constructing strategies of plant virus vectors and their applications for biological researches and commercial purposes are reviewed. The possible disadvantages for using plant virus vectors are also discussed.
