Bayesian estimation of the proportion of genetic clusters for each multilocus genotype (MLG) and population using STRUCTURE software. Analyses were conducted based on 17 microsatellite loci. (a) Proportion of genetic clusters at K = 2 for 257 MLGs of Populus euphratica and P. pruinosa, and 203 MLGs of P. euphratica. The smallest vertical bar represents one MLG. The assignment proportion of each MLG into the population clusters is shown along the y-axis. (b) Geographical distribution of the two genetic clusters and composition of the genetic cluster in each population of P. euphratica. The map was created using the ArcMap package in ArcGIS ver. 9.2 (http://www.esri.com/software/arcgis)
