Nelumbo genome database, an integrative resource for gene expression and variants of Nelumbo nucifera

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. reference genome data center dot whole genome sequencing center dot transcriptome Hi-C center dot PacBio Sequel System center dot Illumina sequencing center dot RNA sequencing center dot DNA sequencing Sample Characteristic - Organism Nelumbo nucifera Machine-accessible metadata file describing the reported data: https://doi.org/10.6084/m9.figshare.13487271

Automated summary

The Nelumbo Genome Database (NGD) is a comprehensive database that provides updated lotus genome information, gene expression and coexpression network data, genetic variants, key traits, and various tools for sequence analysis and gene searching. This valuable genomic resource will facilitate future studies on lotus population genetics and molecular breeding.
