“…Using a bioassay these investigators concluded that the siderophore is taken up by the duckweed plants. Stutz (1964) reported the presence of ferrioxamine B (FOB) in tomato plants extract after a short incubation in nutrient solution containing the siderophore. A variety of plant species exhibited the ability to acquire Fe from microbial hydroxamate siderophores.…”

Iron uptake from ferrated (59Fe) pseudobactin (PSB), a Pseudomonas putida siderophore, by various plant species was studied in nutrient solution culture under short term (10 h) and long term (3 weeks) conditions. In the short term experiments, 59Fe uptake rate from 59FePSB by dicots (peanuts, cotton and sunflower) was relatively low when compared with 59Fe uptake rate from 59FeEDDHA. Iron uptake rate from 59FePSB was pH and concentration dependent, as was the Fe uptake rate from 59FeEDDHA. The rate was about 10 times lower than that of Fe uptake from the synthetic chelate. Results were similar for long term experiments.Monocots (sorghum) in short term experiments exhibited significantly higher uptake rate of Fe from FePSB than from FeEDDHA. In long term experiments, FePSB was less efficient than FeEDDHA as an Fe source for sorghum at pH 6, but the same levels of leaf chlorophyll concentration were obtained at pH 7.3.Fe uptake rates by dicots from the siderophore and FeEDDHA were found to correlate with Fe reduction rates and reduction potentials (E0) of both chelates. Therefore, it is suggested that the reduction mechanism governs the Fe uptake process from PSB by dicots. Further studies will be conducted to determine the role of pH in Fe aquisition from PSB by monocots.

“…A limited number of previous studies have indicated that plants can utilize HS in their absorption of Fe (12,15). The purpose of this study was to confirm these earlier studies, examine the mechanisms involved, and determine if Fe deficiency among some plant species might be related to their ability to acquire Fe from HS.…”

“…Based on the work of Lindsay (1979), they concluded that siderophores satisfy all requirements to serve as iron sources for plants or to serve as chemicals increasing the mass flow of iron to the plant roots. Previously, it was shown by Stutz (1964) that iron could be used by tomato plants when supplied as 59Fe-ferrioxamine B. Page (1966) found Arthrobacter JG-9-detectable substances in the leaves of several crops, indicating the translocation of siderophores through the plant.…”
