Figure 3From: Phenotypic and genetic diversity in Sinorhizobium meliloti and S. medicae from drought and salt affected regions of MoroccoDendrogram showing relationships among S. meliloti and S. medicae isolates, based on phenotypic variation. The UPGMA method was used for the cluster analysis. P-1 to P-11: phenotypic clusters. The numbers indicate S. meliloti isolate # and the numbers with asterisk (*) indicate S. medicae isolate #. Details of the individual clusters are presented in the text and Additional file 1.Back to article page
