摘　　要：反转录转座子几乎是所有植物基因组的主要成分,不仅对基因组的大小、结构、功能和进化,而且对两翼基因的表达水平都有重要影响。该文从反转录转座子的类型和特征、分离鉴定、活性及其对基因组的影响、应用现状等多个方面概述了植物反转录转座子的研究进展,以期为进一步揭示反转录转座子在植物基因组中的功能奠定基础。Retro- transposons are the major components of almost all plant genomes, and they not only have vital impact on the size, structure, function and evolution of plant genomes, but also affect the expression level of two -wing genes. The research progress in plant retro -transposons was reviewed from the following aspects： type and feature, isolation and identification, activity, impact on genomes, and their application. This may make a foundation for the further studies on the functions of retro - transposons in plant genomes.
