How IRON MAN (IMA) is involved in copper homeostasis in plants

Copper (Cu) availability is critical for plant growth and development and for food yield and quality. It is essential for plants to maintain Cu homeostasis. To maintain Cu homeostasis in different tissues and organs, the uptake and transport of Cu must be precisely controlled. IRON MAN (IMA) is a family of small peptides that can bind both iron (Fe) and Cu ions.
