Advances in Flaveria bidentis (L.) Kuntze, A New Exotic Plant
外来植物黄顶菊（Flaveria bidentis）的研究进展

Flaveria bidentis (L.) Kuntze, an annual alien weed of Flaveria Juss. (Asteraceae), was newly found in China. It may be a potential invasive plant because of its very strong reproductive and survival abilities. The following aspects of F. bidentis: name, biological and ecological characteristics, physiological and molecular biology of C4 photosynthesis enzymes, genetics and secondary metabolites, were reviewed. Progresses in the study on the systematics evolution of Flaveria Juss., relationship between photosynthesis characteristics and the evolution of C4 pathway, and four important C4 photosynthesis enzymes are summarized in detail, and the prospects were also discussed. It might provide more information on its invasive characteristics.
