Abstract

Plasmids are genetic materials that help their host bacterial in unfavorable conditions. They have key roles in rhizobial bacteria because of the presence of nif and nod genes. The study of plasmids in rhizobial bacteria is the first step to use their useful capability in sustainable agriculture. In this study 196 isolates of Sinorhizobium meliloti isolated from the nodules of host plants (Medicago sativa cv. Hamedani) grown in different Hamadan soil samples were studied using PLASMID PROFILES technique. The results showed that 13 different plasmids were present among of all isolates and they were grouped in 27 different groups based on Plasmid profile pattern. Shannon diversity and similarity indices were estimated and the results showed that they are different in each physiographic unit. The results also showed that bacterial diversity affected by combination of soil characteristics not by individual factor.
