摘要: 园艺植物包括花卉、蔬菜、果树、部分瓜类(如西瓜(Citrullus lanatus)和甜瓜(Cucumis melo))和茶树(Camellia sinensis), 在植物分类上涉及大量物种。园艺植物的基因组学和遗传学研究具有重要的理论价值和经济意义。基因组测序技术及相关生物信息学工具的发展为园艺植物基因组和分子生物学研究注入了新的活力。睡莲是一种重要的花卉植物, 除了具有观赏价值, 其进化地位也非常特殊, 属于一种早期被子植物类群。最近, 蓝星睡莲(N. colorata)的高质量基因组图谱绘制完成。通过系统分析和比较睡莲基因组与其它被子植物的基因组, 研究者阐明了睡莲的进化位置及相关进化事件。所获得的高质量基因组序列将有助于园艺植物研究者开展深入的分子遗传学研究, 鉴定到控制和调控花器官、花色花香及品质等众多性状的功能基因, 从而推动基础研究的快速发展和加快新品种创制。

Abstract: Horticultural plants include flowers, vegetables, fruit trees, some melon (such as watermelon (Citrullus lanatus), muskmelon (Cucumis melo)) and tea trees (Camellia sinensis), with a large number of species based on plant classification. Genomics and genetics researches for horticultural plants are of important theoretical value and economic significance. The development of genome sequencing technology and related bioinformatics tools greatly facilitate molecular biology researches of horticultural plants. In addition to its important ornamental value, the plant species ‘water lily’ has a very special position in evolutionary, belonging to an early angiosperm group. Recently, a high-quality genome map of an important flower plant, water lily, was generated. Through systematic analysis and genomic comparison of the water lily genome and other angiosperm genomes, the researchers thoroughly elucidated the evolutionary position and related evolutionary events of water lily. Based on the high-quality genomic sequences of these horticultural plants, researchers in horticultural plant science are expected to carry out in-depth molecular genetics research and identify functional genes underlying many traits such as flower organs, flower color, fragrance, and quality, which is expected to promote basic research and accelerate the creation of new varieties.
