摘要:

穗发芽是制约藜麦产量与品质提升的关键瓶颈。为深入理解藜麦穗发芽的调控机制并研发有效的防控策略,综述近5年藜麦穗发芽相关研究进展,重点分析种子生理特性、环境条件及植物激素等关键影响因素,总结其遗传调控基础与防控技术体系。研究表明,藜麦穗发芽受种子休眠特性、胚乳结构及环境温湿度相互作用的共同调控,多种植物激素通过信号网络调节种子休眠与萌发平衡,相关代谢的关键基因已初步解析,其中CqNCED等关键位点为培育抗穗发芽品种提供了重要的分子靶标。当前,多组学解析与生物技术应用已成为藜麦穗发芽研究的重要手段,但其关键调控机制仍有待深入解析,如环境—激素信号的耦合机制尚不清晰、特有休眠调控通路仍缺乏充分验证。未来需要加强基因编辑、单倍体育种等先进育种技术应用,推动藜麦抗穗发芽等优良新种质创制,为藜麦产业高质量发展提供技术支撑。

Abstract:

Pre-harvest sprouting (PHS) is a major constraint limiting the improvement of quinoa yield and quality. To enhance the understanding of the regulatory mechanisms underlying PHS in quinoa and advance research on management strategies, this study reviews the progress on PHS in quinoa over the past five years. Key influencing factors such as seed physiological characteristics, environmental conditions, and phytohormones are discussed, and the genetic regulatory basis and technical approaches for PHS control are outlined. Studies indicate that quinoa PHS is co-regulated by seed dormancy characteristics, endosperm structure, and interactions between ambient temperature and humidity. Various phytohormones coordinate the balance between dormancy and germination through signaling networks, and key genes involved in related metabolic pathways have been preliminarily identified. Key loci such as CqNCED provide important molecular targets for breeding pre-harvest sprouting-resistant varieties. Although multi-omics approaches and biotechnological applications have become important tools in studies on PHS in quinoa, the key regulatory mechanisms still require further elucidation. For instance, the coupling mechanisms between environmental and hormone signaling remain unclear, and the dormancy regulatory pathways specific to quinoa are still not fully validated. Future efforts should strengthen the application of advanced breeding technologies such as gene editing and haploid breeding to promote the development of new quinoa germplasm with enhanced resistance to pre-harvest sprouting, thereby providing technical support for the sustainable development of the quinoa industry.
