Dollar spot database

Dollar spot, caused by Sclerotinia homoeocarpa F.T. Bennett, is one of the most devastating diseases of golf course creeping bentgrass worldwide. The DSTI database hosts the transcriptome data from both Scleotinia homoeocarpa and creeping bentgrass (Cultivar Crenshaw). The database provides information about the repertoire of expressed genes and their expression levels in different conditions in both creeping bentgrass and S. homoeocarpa. We used Illumina's Next Generation Sequencing Technology - "Sequencing By Synthesis" to identify the genes from : 1) S. homoeocarpa grown on PDA plate for 96 h; 2) S. homoeocarpa grown on PDB for 96 h; 3) Crenshaw plants infected with S. homoeocarpa for 96h; and 4) non-inoculated Crenshaw plants. Using keyword or SBS signature or gene sequence, we can search the database for the expressed genes in a given library. The abundances show the level of expression in each library. Since the SBS data is normalized, we can compare the signatures across the libraries. The searched results will be displayed on a new page with hyperlinked signature sequences. Each hyperlink provides the BLAST summary result for a given signature.
