Abstract
Rice is the major food crop grown in all over the world mitigating 60–70% requirement of calories. However, its growth has always been challenged under different abiotic stress. Iron is one such important micronutrient, which pose hazardous effects to its yield and quality under both iron (Fe) deficient and excess condition. Recent research studies have attempted to overcome these iron stress constraints by understanding the function of homeostatic genes involved in it and modulating their expression through developed molecular technologies. These technologies involved overexpression of genes in iron uptake, transport, storage, along with the transcriptomics analysis of whole genome to develop a better quality of rice progenies which can withstand various adverse effects of iron stress. Iron homeostasis pathway involves Strategy I and Strategy II followed by dicotyledonous and monocotyledonous plants. However, in the case of rice, several genes involved in both strategies have found to be responsive under Fe-deficient and excess condition. Interaction of other metals present in the soil along with pH can affect the iron uptake in rice. Transgenic rice can become a strong contender in iron stress condition controlling iron uptake, translocation and storage.
