Research Abstract

Endophytic diazotrophs isolated from sweet potato were characterized. The isolated Bradyrhizobium showed acetylene reduction activity in the medium containing carboxylic acids as the carbon source under micro-aerobic conditions. Colonization in the stems after inoculation of the Bradyrhizobium to the roots was observed in sweet potatoes. These results suggested that the Bradyrhizobium endophyte can express nitrogenase activity in the microsites with low oxygen tension in plants.
