Iron is an essential micronutrient required by plants for their growth and development. The
iron in the soil is abundant but is not bioavailable to the plants. To combat this issue, plants
have evolved different strategies for efficient iron uptake and enabling plants to adapt to low
iron conditions. The strategies comprised iron acquisition from the soil, its transport from
roots to shoots, and intracellular storage. The iron mobilization in plants generally takes
place through chelating with citrate, phytosiderophores, nicotianamine, mugineic acid and in …

Iron (Fe) is an essential micronutrient that is indispensable for plant growth, human
development, and overall health. Rice and wheat are the main staple cereals worldwide, but
their common cultivars contain meager amounts of Fe, which are mostly located in the outer
bran layers. The development of substantial Fe-rich rice and wheat germplasms through
traditional breeding has been challenging due to the limited availability of significant Fe
resources. To survive, plants have evolved two distinct molecular strategies to perceive and …
