โฆ Synopsis
An iron-inefficient variety of peanut plant, when grown hydroponically with the catechol siderophore of Rhizobium (peanut isolate), showed increased growth and chlorophyll content compared with plants grown with Fe alone. The siderophore, when used in concentrations less than the concentrations of Fe, was still effective in growth promotion, indicating that it might function as a shuttle agent, solubilizing and supplying Fe to the plant. Similar results were also obtained with desferrioxamine B.

The ability of a siderophore-catabolizing bacterium to assimilate ferric ion was examined. While the bacterium utilizes the siderophore deferrioxamine B (DFB) as a carbon source, it was incapable of using the ferric ion analogue (ferrioxamine B) as an iron source. It did, however, assimilate the fer
