摘　　要：观察了拟南芥属、盐芥属以及相关属的叶表皮微形态特征,并测定了叶绿体DNA的trnL内含子和trnL-F基因间隔区序列,对这两个属的亲缘关系进行了比较研究。研究结果初步表明:盐芥属与拟南芥属之间的亲缘关系较远,前者应置于大蒜芥族,与该族中的山嵛菜属关系最近;后者则应放在南芥族而不是大蒜芥族。Systematics relationship of Arabidopsis, Thellungiella and related genera （Brassicaceae） from China were studied using leaf epidermal features and sequence analysis of the chloroplast DNA （cpDNA） trnL intron and trnL-F spacer. The results of this study indicate that Thellungiella is far away from Arabidopsis and should be put in Sisymbrieae. Within Sisymbrieae, it is closely related to Eutrema. However, Arabidopsis should be in Arabideae rather than Sisymbrieae.
