PIsolation and Characterization of Salt Tolerant Strains of Sinorltizobium meliloti
Twenty four strains of Sinorhizobium meliloti were isolated from<br /> root nodules of alfalfa plants. Host plants collected from different<br /> agroclimatic regions of Ninavah province-Iraq. Five strains, vis. FA7,<br /> FA8, FAlO, FAll and FA12 were found tolerant to 6% NaCI. Al...

| description | Twenty four strains of Sinorhizobium meliloti were isolated from<br /> root nodules of alfalfa plants. Host plants collected from different<br /> agroclimatic regions of Ninavah province-Iraq. Five strains, vis. FA7,<br /> FA8, FAlO, FAll and FA12 were found tolerant to 6% NaCI. All the<br /> five strains were able to grow on rhizobia! minimal medium. The five<br /> studied strains showed multiple antibiotic resistance. The more sufficient<br /> production in shoot group in alfalfa plants found when the plants<br /> inoculated with F A8 and FA 7 strains. pH changes in MSY solid medium<br /> study revealed that changes in pH towards acidity. Reduction in colony<br /> forming units (CFU) was observed under salt conditions in comparison<br /> with normal conditions. Production of cell surface molecules in these five<br /> strains , such as, P-(1 ----+ 3) glucans, cellulose fibrils and<br /> exopolysaccharides were also studied. Heat curing of Sym plasmids study<br /> revealed that at least one of the salt tolerant genes lays on Sym plasmids. |
