Additional file 2: of Genomic, transcriptomic, and proteomic approaches towards understanding the molecular mechanisms of salt tolerance in Frankia strains isolated from Casuarina trees

The effect of salt stress on the vesicle formation and nitrogenase activity by salt-tolerant and salt-sensitive Casuarina isolates. Cultures were grown under nitrogen-deficient conditions with various degrees of salt or osmotic stress. Panel (A) shows vesicle production. Panel (B) show nitrogenase activity expressed on a per-vesicle basis. (PPTX 64 kb)
