摘要

双单倍体(DH)技术和合成单倍体方法可以大大缩短育种周期,从而提高育种效率。与传统育种方法相比,DH 技术的优势在于能够快速产生近交系,而合成 apomixis 则能有效固定杂交种的活力。在这篇综述中,我们将重点讨论:(i) 在识别和鉴定单倍体诱导(HI)基因方面的最新进展;(ii) HI 的分子机制;(iii) 自发基因组加倍;以及 (iv) 作物合成 apomixis。我们还讨论了利用 DH 技术和合成 apomixis 的未来作物育种计划所面临的挑战和潜在解决方案。最后,我们对将 DH 和合成杂交技术整合到精准育种和从头驯化中提出了自己的看法。

Doubled haploid technology and synthetic apomixis: Recent advances and applications in future crop breeding.

Doubled haploid (DH) technology and synthetic apomixis approaches can considerably shorten breeding cycles and enhance breeding efficiency. Compared with traditional breeding methods, DH technology offers the advantage of rapidly generating inbred lines, while synthetic apomixis can effectively fix hybrid vigor. In this review, we focus on (i) recent advances in identifying and characterizing genes responsible for haploid induction (HI), (ii) the molecular mechanisms of HI, (iii) spontaneous haploid genome doubling, and (iv) crop synthetic apomixis. We also discuss the challenges and potential solutions for future crop breeding programs utilizing DH technology and synthetic apomixis. Finally, we provide our perspectives about how to integrate DH and synthetic apomixis for precision breeding and de novo domestication.
