摘要
Miniature Ping(mPing)是小型反向重复转座子(Miniature Inverted-Repeat Transposable Elements,MITEs)类转座子Tourist-like超家族重要成员,是水稻基因组内检测到的第一个活跃的MITEs,是MITEs大家族中少数低拷贝且可以在自然状态下维持转座活性的成员之一,因此,mPing是转座子相关领域研究的良好素材。该文综合阐述了近年来国内外有关mPing的结构、转座酶供体、激活特性以及对基因组的影响等方面的研究进展,为进一步深入探究MITEs的转座机制以及mPing转座子的开发利用提供资料。
Miniature Ping （mPing） is a prominent member in Tourist-like superfamily of Miniature Invert-ed-Repeat Transposable Elements （MITEs） .It is the first active MITEs identified in the rice genome and one of the few MITEs which keep low copy numbers and maintain mobilization under natural condition . T herefore ,it is an irreplaceable material for the study related to transposon .T his paper comprehensively demonstrates research progress of mPing through analyzing its structure ,transposase donor ,activation characteristics ,and its influence on genome ,looking forward to lay foundation on advanced research of transposition mechanism of MITEs and the further development and utilization of mPing .
