Advances in apomixis for climate-resilient crops of the future: a molecular perspective
摘要
Apomixis, the clonal formation of seeds without fertilization or meiosis, represents a transformative strategy to stabilize hybrid vigor and enhance crop resilience under climate stress. By enabling the fixation of elite genotypes across generations, apomixis could reduce reliance on repeated hybridization and strengthen resilience in stress-prone environments. Recent molecular advances have uncovered key regulators of apomeiosis, parthenogenesis, and endosperm development, while CRISPR-based approaches demonstrate the feasibility of synthetic apomixis in cereals. Synthetic biological approaches demonstrate that incorporating apomictic genes into rice and other model systems is feasible. However, translation into major crops remains limited due to an incomplete understanding of regulatory networks, developmental incompatibilities, and technical barriers in polyploid species. This review explores current molecular insights, highlights emerging applications of CRISPR-based and multi-omics approaches, and examines the potential of apomixis to develop climate-resilient and economically viable crop systems. Furthermore, we examined why bridging mechanistic knowledge with translational research, while addressing ecological and economic challenges, is crucial to unlock apomixis as a key innovation for sustainable agriculture.
