中文摘要：

近年来,多种植物RNA病毒载体被广泛地应用于外源基因的表达、植物病毒学和植物病理学基础理论的研究中.番茄丛矮病毒（Tomato bushy stunt virus,TBSV）是番茄丛矮病毒科（Tombusviridae）番茄丛矮病毒属（Tombusvirus）的典型成员.TBSV病毒基因组复制、转录和翻译等分子机制的研究取得了巨大的进展,使得利用TBSV构建稳定、高效的表达载体成为可能.

英文摘要：

Plant virus RNA-based vectors have been developed for expressing recombinant proteins, and studying plant virology and phytopathology in recent years. Tomato bushy stunt virus （TBSV） is the type species of the plant-infecting Tombusvirus genus in the family Tombusviridae. Important advances were made in the molecular biology of TBSV, such as gene expression, genome replication, and recombination. Those advances in TBSV make it possible to be a candidate of plant virus RNA-based expression vector.
