无融合生殖是种子无性繁殖的现象。由于无融合生殖可以产生与母本完全相同基因型的克隆后代，因此它在基因型固定和加速农业育种策略方面具有重要的应用。将无融合生殖技术引入主要农作物，可使作物的上级基因型永久固定，简化杂交制种程序，并可使无性繁殖的作物提纯复壮。虽然无融合生殖在400多个植物物种中自然发生，但在主要作物中很少见。目前，随着对无融合生殖认识的加深，人工无融合生殖研究取得了一些成果。然而，由于普遍存在的局限性，要实现无融合生殖在作物育种中的大规模应用还有很长的路要走。在这里，我们比较了无融合生殖和有性植物生殖的发育特征，并回顾了最近确定的无融合生殖基因，转座子，表观遗传调控和遗传事件导致无融合生殖。最后总结了农作物无融合生殖工程的可能策略和潜在基因。
Apomixis is the phenomenon of clonal reproduction by seed. As apomixis can produce clonal progeny with exactly the same genotype as the maternal plant, it has an important application in genotype fixation and accelerating agricultural breeding strategies. The introduction of apomixis to major crops would bring many benefits to agriculture, including permanent fixation of superior genotypes and simplifying the procedures of hybrid seed production, as well as purification and rejuvenation of crops propagated vegetatively. Although apomixis naturally occurs in more than 400 plant species, it is rare among the major crops. Currently, with better understanding of apomixis, some achievements have been made in synthetic apomixis. However, due to prevailing limitations, there is still a long way to go to achieve large-scale application of apomixis to crop breeding. Here, we compare the developmental features of apomixis and sexual plant reproduction and review the recent identification of apomixis genes, transposons, epigenetic regulation, and genetic events leading to apomixis. We also summarize the possible strategies and potential genes for engineering apomixis into crop plants.
