摘　　要：莲(Nelumbo)是我国特色的水生经济作物,具有很高的观赏、食用、药用等价值。近年来,在莲基因组学、遗传学和分子生物学等研究领域取得一系列重要进展,绘制了莲属两个种的参考基因组图谱,构建了莲高密度遗传连锁图谱,开展了莲观赏性状(花色、开花时间和花型)、食用品质(莲子和莲藕营养成分)、药用成分(生物碱和类黄酮)和逆境胁迫(水淹、低温、弱光、重金属和盐碱)响应的分子机制研究。本文从莲基因组测序、遗传图谱构建、重要性状基因挖掘和功能分析等方面进行了系统的综述,并对今后研究的重点和发展方向进行了展望,以期为莲的基础研究和遗传改良提供参考。Lotus(Nelumbo),a significant aquatic crop in China,possesses considerable ornamental,edible,and medicinal value.Over the past decade,significant progress has been achieved in the domains of genomics,genetics,and molecular biology pertaining to lotus.The reference genomes of two Nelumbo species have been constructed,along with high-density genetic linkage maps.Furthermore,various studies have explored the molecular mechanisms of ornamental traits(flower color,flowering time,and flower type),food quality(seed and rhizome nutrients),medicinal components(alkaloids and flavonoids),and stress responses(flooding,low temperature,low light,heavy metals,and salinity)of lotus.In this paper,the genome sequencing,genetic mapping,gene mining,and functional analysis of important traits in lotus are systematically reviewed.Potential goals and future directions are also discussed to provide a reference for research and genetic improvement of lotus.
