外来植物黄顶菊（Flaveria bidentis）的研究进展

黄顶菊(Flaveria bidentis)是近年来新发现的一种外来植物,隶属菊科黄菊属,为一年牛草本,是较为少见的双子叶C4植物.黄顶菊异常强大的繁殖能力和牛存能力已使其成为一种潜在的入侵植物.对黄顶菊的译名、生物及生态学特性、遗传学及次生代谢产物的研究状况进行了概述;重点对黄菊属植物的系统进化史、光合生理特性与C4途径演化的关系,以及黄顶菊体内碳酸酐酶、NADP-苹果酸酶、苹果酸脱氢酶Rubisco及其活化酶等C4光合重要酶的分子及基因工程研究进行了综述;并对今后的研究提出了展望.

Advances in Flaveria bidentis (L.) Kuntze, A New Exotic Plant

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.
