Long-distance dispersal (LDD) plays an important role in shaping the distribution of global biodiversity. Polyploidy could favour invasion and thereby facilitate LDD. However, how and to what extent polyploidy interacts with LDD remain unclear. Here, we test the putative role of polyploidy in the global dispersal of a cosmopolitan genus Rorippa.

协同多倍体化和长距离传播使黄芥菜草本植物实现全球多样化

长距离扩散（LDD）在塑造全球生物多样性的分布中发挥着重要作用。多倍体可能有利于入侵，从而促进 LDD。然而，多倍体如何以及在多大程度上与 LDD 相互作用仍不清楚。在这里，我们测试了多倍体在世界性Rorippa属全球传播中的假定作用。
