摘要
杂种优势利用是提升作物产量、抗逆性和品质的重要手段之一,目前杂种优势已被广泛应用于杂交育种研究中。随着分子生物学、基因工程、高通量测序技术等的高速发展,研究人员在不同层面不断探索作物杂种优势的遗传基础,杂种优势数量性状基因座(Quantitative trait locus,QTL)定位与相关基因挖掘研究是其中的重要方面,对解析杂种优势分子机理具有重要的理论意义。本文对玉米、水稻、大豆等主要农作物中已定位的株型、粒质量及产量等杂种优势相关QTL或克隆基因的类型、功能及分子机理进行阐述和总结,以期通过结合现代分子生物学技术与高通量组学数据分析技术,深度解析作物杂种优势遗传基础,为推动杂种优势高效利用提供参考。
Heterosis utilization is an effective method for increasing crop yield,improving resistance and quality.At present,heterosis has been widely applied in hybrid breeding.With the rapid development of molecular biology,gene engineering and high-throughput sequencing technology,researchers have been exploring the genetic basis of crop heterosis from different dimensions.Among those,quantitative trait locus(QTL)mapping and heterosis-related genes discovering are the most important aspects of heterosis,which are helpful for understanding the molecular mechanism of heterosis.Therefore,this paper described and summarized the types,functions and molecular mechanisms of QTLs or cloned genes related to heterosis,such as plant type,grain weight and yield,which had been located in corn,rice,soybean and other major crops,aiming to provide a reference for in-depth analysis of the genetic basis of crop heterosis and promote the efficient utilization of heterosis through the combination of modern molecular biological technology and high-throughput omics data analysis.
