Compositdb is a database of information on Compositae species that was developed jointly by the laboratories of Richard Michelmore at UC Davis and Steve Knapp at Oregon State University. At present the laboratories "are primarily focused on sunflower and lettuce but will expand it to include any Compositae species for which there is sufficient data and interest." In addition to Lettuce and Sunflower Databases, the site links to several locally developed Tools like Genoplayer, a "program for visualizing and querying genetic data." Although Compositdb was initially supported by the USDA-ARS, the project is currently lacking funding. Thus, multiple sections of the site have not been updated in more than a year. Nonetheless, this storehouse of Compisitae-related information will surely be of interest to agronomists, geneticists, botanists, and others.
