摘　　要：水生植物基因组学研究对认识水生植物特性,明确水生植物功能,指导水生植物育种中发挥重要作用;而全基因组测序技术是推动水生植物基因组学研究的主要驱动力。全基因组序列是水生植物系统发育分析的重要单元,能够为水生植物QTL定位工作提供分子标记和图谱信息,降低水生植物全基因组重测序和功能基因组研究的难度。本研究就水生植物全基因组测序及其应用进行了归纳和总结,并对其存在的问题和进一步研究进行了分析与展望。目前已有9种水生植物完成全基因组序列测序,其中莲与紫萍基因组序列经过多次更新具有较高质量,而莲基因组序列应用最为广泛。为加快水生植物基因组学发展,推动水生植物基因组学与其他学科交叉融合,需增加生产实践中广泛应用水生植物物种的测序力度并建立完善的水生植物数据库。Aquatic plant genomics plays an important role on understanding the features and functions of aquatic plants and promoting the breeding of aquatic plants.Besides,aquatic plant genomics is driven by whole genome se-quencing techonology.Whole genome sequences are important units of phylogenetic analysis,apply molecular markers and map information for aquatic plant QTL mapping,facilitate aquatic plant whole genome resequencing and functional genomic research.Research progress on aquatic plant whole genome sequencingand its utilization on aquatic plant genomics are summarized and concluded,and the future research on aquatic plant genomics is prospected.9 species of aquatic plants have been whole genome sequenced,in which lotus and common duckweed genome sequences are of high quality due to the continuous updating.Lotus genome has been widely used so far.To accelerate the progress of aquatic plant genomics and promote the intercross and fusion with multi-disciplines,more species with wide applications should be sequenced and integrated aquatic plant database should be constructed.
