A database for the Compositae species, funded by USDA/ARS and created as a collaboration between the laboratories of Steve Knapp at Oregon State University and Richard Michelmore at UC Davis. 

Currently focused on sunflower and lettuce, it will expand to include other Compositae species for which there is sufficient data & interest. 

Due to funding constraints and the uncertainty of long-term funding, we are not attempting a comprehensive database. Instead, we aim to archive as much information as possible that is not available elsewhere and provide links to access information that is obtainable from other sources.
