Figure 4From: Phenotypic and genetic diversity in Sinorhizobium meliloti and S. medicae from drought and salt affected regions of MoroccoDendrogram showing genetic relationships among the isolates of S. meliloti and S. medicae. The UPGMA method was used for cluster analysis. G-1 to G-13: genotypic clusters. The isolates from the same phenotypic clusters (clusters P-1 to P-11, Figure 3) are denoted by the same colour, as shown in Figure 3. The numbers indicate S. meliloti isolate # and the numbers with asterisk (*) indicate S. medicae isolate #.Back to article page
