Micronutrient deficiency in cultivable soil, particularly that of iron (Fe) and
zinc (Zn), is a major productivity constraint in the world. Low Fe availability
due to the low solubility of the oxidized ferric forms is a challenge. An
experiment was, thus, executed to assess the performance of eight
genetically diverse rice genotypes on Fe-sufficient (100 mM) and Fe-deficient
(1 mM) nutrient solution, and their ability to recover from Fe deficiency was
measured. Fe efficiency under Fe deficiency in terms of biomass production
showed a significant positive correlation with the root release of
phytosiderophore (PS) (R2 D 0.62 ). This study shows that the Fe deficiency
tolerance of Pusa 33 was related to both a high release of PS by the root and
an efficient translocation of Fe from the root to the shoot as the Fe–PS
complex, which could be useful for improving the Fe nutrition of rice
particularly under aerobic conditions.
