Welcome to the GSAD: Genome Size in Asteraceae Database (Release 2.0)

The GSAD is an exhaustive catalogue of genome size data for the family Asteraceae. Genome sizes are available for 1,219 species based on 2,768 records from 133 publications, covering approximately 5% of species, 10% of genera, 40% of tribes and 50% of subfamilies.

The main goal of the database is to serve as a tool aiming to make Asteraceae genome size information accessible to scientists interested in genome characterisation and evolution with basic (e.g. plant molecular systematics, NGS programs, evo-devo research) or applied (e.g. barcoding, breeding, races or raw material identification) focuses.

The database holds data from papers already published or in press up to June 2013. Regular updates are planned.
