Expressions of Fe deficiency-inducible genes were analyzed to estimate the Fe status in plants. The reducibility of Fe chelates by roots was measured to determine the mechanism underlying differences in availability. ![]() ![]() EDDHA-Fe, EDTA-Fe, and citrate-Fe were used as controls. The availability of PDMA-Fe to cucumber was evaluated in a calcareous substrate and hydroponic cultures at pH 7.0–9.0 by determining chlorophyll level, PSII activity, and Fe uptake. We aimed to investigate whether PDMA-Fe is also a good Fe source for dicots. Recently, the synthetic PS proline-2′-deoxymugineic acid (PDMA) has been developed as a moderately biodegradable Fe fertilizer for grasses. Phytosiderophores (PS) from grasses solubilize sparingly soluble iron (Fe), and the resultant PS-Fe is an Fe source even for dicots.
