Sacred lotus (Nelumbo nucifera, or lotus) is one of the most widely grown aquatic plant species with important uses, such as in water gardening and in vegetable and herbal medicine. A public genomic database of lotus would facilitate studies of lotus and other aquatic plant species. Here, we constructed an integrative database: the Nelumbo Genome Database (NGD, http://nelumbo.biocloud.net ). This database is a collection of the most updated lotus genome assembly and contains information on both gene expression in different tissues and coexpression networks. In the NGD, we also integrated genetic variants and key traits from our 62 newly sequenced lotus cultivars and 26 previously reported cultivars, which are valuable for lotus germplasm studies. As applications including BLAST, BLAT, Primer, Annotation Search, Variant and Trait Search are deployed, users can perform sequence analyses and gene searches via the NGD. Overall, the valuable genomic resources provided in the NGD will facilitate future studies on population genetics and molecular breeding of lotus.
荷花（Nelumbo nucifera，即莲）是水生植物中分布最广的物种之一，具有重要的用途，如在水培园艺和蔬菜及草药方面。荷花的公共基因组数据库将有助于对荷花和其他水生植物物种的研究。在这里，我们构建了一个综合性的数据库：荷花基因组数据库（Nelumbo Genome Database，NGD，http://nelumbo.biocloud.net）。该数据库是荷花基因组最新组装的集合，包含了不同组织中基因表达和共表达网络的信息。在 NGD 中，我们还整合了 62 个新测序的荷花品种和 26 个先前报道的品种的遗传变异和关键性状，这对于荷花种质研究非常有价值。作为包括 BLAST、BLAT、Primer、Annotation Search、Variant 和 Trait Search 在内的应用程序，用户可以通过 NGD 进行序列分析和基因搜索。总的来说，NGD 中提供的有价值的基因组资源将有助于未来对荷花群体遗传学和分子育种的研究。
