Iron transport and homeostasis in plants: current updates and applications for improving human nutrition values and sustainable agriculture
(Springer Science and Business Media B.V., 2023-02-23T00:00:00) Khan, Shahirina; Kaur, Karambir; Kumar, Vinay; Tiwari, Siddharth
Agriculture and plant science face a formidable challenge in feeding the world�s expanding population in a sustainable, sufficient, and nutrient-rich manner. The mineral micronutrient composition of food crops merits special consideration. Globally, cultivated soil and plant micronutrient deficits have negative impacts on crop yield, plant nutritional value, human health and well-being. This article reviews the present knowledge on iron (Fe) uptake, transport, subcellular translocation, and its regulation at the molecular level mainly on Oryza sativa and Arabidopsis thaliana, which typically represent graminaceous and non-graminaceous plants, respectively. This study emphasizes the recent advancements in various approaches, including high-throughput technologies (NGS, proteomics, ionomics) and genetic engineering such as CRISPR/Cas for Fe biofortification in crop plants and their subsequent impact on human health. The aforementioned information can be applied to elevate the Fe content in model plants along with various fruit and vegetable crops. This might be helpful for nutritious food production for large human population in the world to achieve one of the most important Sustainable Development Goals (SDGs) for nutrition security. � 2023, The Author(s), under exclusive licence to Springer Nature B.V.

Ascorbic acid (AsA) also known as vitamin C is considered as an essential micronutrient in the diet of humans. The human body is unable to synthesize AsA, thus solely dependent on exogenous sources to accomplish the nutritional requirement. AsA plays a crucial role in different physiological aspects of human health like bone formation, iron absorption, maintenance and development of connective tissues, conversion of cholesterol to bile acid and production of serotonin. It carries antioxidant properties and is involved in curing various clinical disorders such as scurvy, viral infection, neurodegenerative diseases, cardiovascular diseases, anemia, and diabetes. It also plays a significant role in COVID-19 prevention and recovery by improving the oxygen index and enhancing the production of natural killer cells and T-lymphocytes. In plants, AsA plays important role in floral induction, seed germination, senescence, ROS regulation and photosynthesis. AsA is an essential counterpart of the antioxidant system and helps to defend the plants against abiotic and biotic stresses. Surprisingly, the deficiencies of AsA are spreading in both developed and developing countries. The amount of AsA in the major food crops such as wheat, rice, maize, and other raw natural plant foods is inadequate to fulfill its dietary requirements. Hence, the biofortification of AsA in staple crops would be feasible and cost-effective means of delivering AsA to populations that may have limited access to diverse diets and other interventions. In this review, we endeavor to provide information on the role of AsA in plants and human health, and also perused various biotechnological and agronomical approaches for elevating AsA content in food crops. � 2022, Prof. H.S.
