Fe deficiency-inducible genes encoding functional or putative transporters. A) Fe transporters. OsIRT1 and OsIRT2, Fe²⁺ transporters (Bughio et al. 2002; Ishimaru et al. 2006); OsYSL13, a putative MAs–metal complex transporter (Koike et al. 2004). B) Copper transporters. OsHMA5, a putative HMA-family protein (Lee et al. 2007). C) Monocation transporters. Na⁺ transporter, putative sodium transporter; K⁺ transporter, putative potassium transporter.
