摘要: 单倍体的产生可以极大地提高育种效率。单倍体诱导的产生主要包括体外配子体组织培养和体内染色体消除。文章综述了体内单倍体诱导的几种策略及其发展和应用,还对目前单倍体诱导系的作用机制进行了介绍,并重点介绍了着丝粒蛋白CENH3介导的单倍体诱导机制。

Abstract: Haploid induction largely improves the efficiency of breeding. Haploid production mainly consists of in vitro gametophytic tissue culture and in vivo chromosome elimination. In this review, we focus on various strategies for in vivo haploid induction, along with recent research progresses and practical applications. Additionally, we provide an overview of the potential mechanisms underlying key haploid inducers, with a particular emphasis on the centromeric protein CENH3 mediated haploid induction.
