Pseudostellaria longipedicellata S. Lee, K. Heo & S.C Kim is newly identified species in Korea. Because P. longipedicellata shares almost all morphological characters with Pseudostellaria palibiniana (Takeda) Owhi except a pedicel length that expands significantly during flowering and fruiting seasons. To understand P. longipedicellata, we have investigated its genome, transcriptomes, phylogeny, geographical distribution, and physiology. Pseudostellaria Database (http://www.pseudostellaria.net/) has been established for storing all results from our studies, as well as integrated and interdisciplinary web-based platform for diverse analyses. It contains five major sections: i) Phylogeny section covers 814 Pseudostellaria samples we have collected in Korea with GPS coordination and their marker sequences. ii) Herbarium section provides 224 Pseudostellaria specimen from the samples with high quality scanned images. iii) Phenology section contains continuous pictures for monitoring growth process of P. longipedicellata and more than than 10 years’ temperature data of its natural habitats. iv) Omics section have two Pseudostellaria genomes (P. longipedicellata and P. palibiniana), transcriptomes (three different stages of pedicel growth datasets of P. longipedicellata and P. palibiniana), and gene family (cytochrome P450s and GATA, TCP, and NAC transcription factors) analysis results. v) Tools section provides BLAST searches against Pseudostellaria genomes and transcriptomes and GlobalScrapTM which supports virtual space for collecting data and interdisciplinary analysis tools for all types of data in the database. We believed that Pseudostellaria Database will be an information hub as well as fundamental platform for understanding Pseudostellaria genus in all possible research areas.
