| Species name: Chinese bellflower (Platycodon grandiflorus [Jacq.] A.DC.)|
Platycodon grandiflorus represents the Campanulaceae, which is a close relative of the Compositae. Evolutionary genomic analyses of Platycodon are useful for elucidating genetic and genomic changes associated with the origin and early diversification of the Compositae. Platycodon grandiflorus is a perennial herb native to east Asia (http://en.wikipedia.org/wiki/Platycodon_grandiflorus). The plant is a popular ornamental, and its root is used in salads or as an anti-inflammatory in the treatment of coughs and colds. It has a gametophytic chromosome number of 9, but its genome size is unknown.

We generated the EST library described above, which is being used to determine the distribution of whole genome duplications in the Compositae and closely related families.
