摘要

Crambe tataria is an endangered species in the Romanian flora, with a limited number of populations. For Romanian populations, there are no prior data concerning their genetic structure and its correlation with geographic distribution. In the present study, 15 populations from the three main regions of species distribution, North-East (Moldova), South (Muntenia) and West-Central (Transylvania), were investigated using ISSR markers. The UPGMA clustering revealed five distinct groups showing close genetic relations between individuals from all three regions, while Bayesian clustering showed four clusters which are represented in all individuals, indicating ongoing admixture in all populations. The configuration of the ISSR data suggests that C. tataria populations established in Romania have mixed origins being most probably a result of multiple colonization events.
