Bioresources for genetic studies on the Anthemideae
The Anthemideae, one of the tribes in the Asteraceae, consists of 111 genera and about 1800 species, including many economically important species. We possess a large collection of Anthemideae resources, particularly for the genus Chrysanthemum. The genus Chrysanthemum contains autoploid species ranging from diploid to decaploid, and the economically important ornamental species Chrysanthemum morifolium is mainly hexaploid, which complicates genetic analyses. In order to overcome this difficulty, we propose a system using diploid wild species that share similar morphological and physiological properties with C. morifolium. The simple genetic behavior of the ligule color trait was confirmed using F2 lines from a cross between Chrysanthemum seticuspe and Chrysanthemum makinoi, suggesting their potential as reference species for C. morifolium. Our resources, including Anthemideae species, are distributed by the National BioResource Project in Japan (http://www.shigen.nig.ac.jp/chrysanthemum/top.jsp).
