Abstract: 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.

Key words: transposon, transposition, gene expression, regulation modes
