Effect of salt stress on the physiology of Frankia sp strain CcI6.

ABSTRACT

Actinorhizal plants are able to overcome saline soils and reclaim land. Frankia sp strain CcI6 was isolated from nodules of Casuarina cunninghamiana found in Egypt. Phylogenetic analysis of Frankia sp. strain CcI6 revealed that the strain is closely related to Frankia sp. strain CcI3. The strain displays an elevated level of NaCl tolerance. Vesicle production and nitrogenase activity were also influenced by NaCl.
