摘要
Mu因子是玉米中的一类新型转座因子。本文介绍了Mu因子的发现、分布和类型,对Mu因子的基本遗传特征(突变类型、突变频率、插入专一性、靶位点等)和Mu因子活性的调控(生长发育调控、表观遗传调控)进行了综述,重点论述了Mu活性的调控和应用Mu因子进行玉米插入诱变和基因标签的研究进展。
Mutator elements are a novel type of transposable element in maize. In this review, the discovery, distribution and subfamilies of mutator elements are briefly introduced. The basic attributes of mutator elements and regulation of mutator activity are described as well. The emphasis of this review is on the regulation of Mu activity and the utlization of mutators for maize insertional mutagenesis and gene tagging.
