چکیده انگلیسی
Alternanthera philoxeroides (Mart.) Grisb was introduced into China in the 1930s, and today occurs in most regions of southern China. Techniques using random amplified polymorphic DNA (RAPD) and inter-simple sequence repeats (ISSR) markers were applied to analyze genetic diversity of this invasive, weedy species. The fragments amplified by both 28 RAPD primers and 23 ISSR primers showed no polymorphic bands within and among the seven populations sampled. These results might be a consequence of the short introduction history in China and the clonal propagation of this aquatic plant. Although A. philoxeroides is widely distributed in China, the molecular data indicated its genetic diversity is extremely low, which implies that the low genetic diversity did not affect the success of its expansion in China. The rapid range expansion of A. philoxeroides is most likely the result of a massive clonal propagation since its introduction.
