Iron uptake and homeostasis related genes in potato cultivated in vitro under iron deficiency and overload

► First report on gene expression related to iron uptake in potato. ► Identification of potato ESTs related to iron uptake, homeostasis and storage. ► Identification of 3 copies of ferritins gene with different expression patterns. ► Under high iron condition, iron overload is restricted in root. ► Under iron deficiency condition, a strong gene expression change was observed.
