植物转座子与基因表达调控

摘要

植物转座子是植物基因组中可移动的DNA重复序列,在植物基因组进化、基因表达调控、系统发育和遗传多样性评价方面具有重要作用.综述了植物转座子分类、起源和转座机制以及转座子与宿主基因组间的表观遗传互作,阐述了不同转座子对基因表达调控方式,并对今后研究前景进行了展望,旨为全面了解植物转座子的功能提供参考.%Plant transposon is a mobile DNA repeat sequence of plant genome,playing an important role in plant genome evolution, gene expression regulation,system development,and evaluation of genetic diversity. This paper reviews the classification,origin,and transposition mechanism of plant transposons,and epigenetic control between transposon and host genome,and elaborates the regulatory pattern of different transposons on gene expressions,and the future research is prospected,aiming at providing reference for fully understanding the function of plant transposons.
