Schematic diagram of membrane transporter genes involved in low Cd accumulation in barley leaves. Some representative genes encoding membrane transport proteins transport Cd and other ions on the plasma membrane and tonoplast in W6nk2 and Zhenong8. Squares and circles represent transporter genes expressed in W6nk2 and Zhenong8, respectively. Red, grey and green symbols indicate Cd-induced up-regulation, no change and down-regulation of the transporter genes in comparison to the control, respectively. ABC, ABC transporter family protein; AMTP, Ammonium transporter; ASL, ATP sulfurylase; HA, H+-ATPase; HXCP, Hexose carrier protein; ITYSL, Iron transporter yellow stripe 1-like; KTP, Potassium transporter; MST, monosaccharide (M) transporter; Org. ac., organic acids; PC, phytochelatin; PEPT, peptide transporter; PTA, P-type ATPase; ROS, reactive oxygen species; SRRP, Stripe rust resistance protein; SUTP, Sugar transport protein; ZFP, Zinc finger protein; ZIP, Zinc transporter protein
