The term 'ornamental plant' refers to all plants with ornamental value, which generally have beautiful flowers or special plant architectures. China is rich in ornamental plant resources and known as the "mother of gardens". Genomics is the science of studying genomes and is useful for carrying out research on genome evolution, genomic variations, gene regulation, and important biological mechanisms based on detailed genome sequence information. Due to the diversity of ornamental plants and high sequencing costs, the progress of genome research on ornamental plants has been slow for a long time. With the emergence of new sequencing technologies and a reduction in costs since the whole-genome sequencing of the first ornamental plant (Prunus mume) was completed in 2012, whole-genome sequencing of more than 69 ornamental plants has been completed in <10 years. In this review, whole-genome sequencing and resequencing of ornamental plants will be discussed. We provide analysis with regard to basic data from whole-genome studies of important ornamental plants, the regulation of important ornamental traits, and application prospects.
“观赏植物”一词指的是所有具有观赏价值的植物，这些植物通常拥有美丽的花朵或独特的植物形态。中国拥有丰富的观赏植物资源，被誉为“园林之母”。基因组学是研究基因组的科学，基于详细的基因组序列信息，它有助于开展基因组进化、基因组变异、基因调控及重要生物学机制的研究。由于观赏植物种类多样且测序成本高昂，长期以来观赏植物的基因组研究进展缓慢。自2012年首个观赏植物（梅花）完成全基因组测序以来，随着新测序技术的出现和成本的降低，在不到10年的时间里已完成了69种以上观赏植物的全基因组测序。在这篇综述中，将讨论观赏植物的全基因组测序和重测序。我们对重要观赏植物全基因组研究的基础数据、重要观赏性状的调控及应用前景进行了分析。
