Plant KUP/HAK/KT transporters were identified by sequence homology with K+ uptake transporters from bacteria and high-affinity K+ transporters from fungi

Fig. 3. Plant KUP/HAK/KT transporters were identified by sequence homology with K+ uptake transporters from bacteria and high-affinity K+ transporters from fungi. Based on hydrophobicity analysis, they would possess ten transmembrane segments (displayed in yellow) and a long cytosolic loop between the second and third segment. Based on genome sequence analysis, thirteen HAK genes are present in Arabidopsis thaliana and 26 in rice (Oryza sativa) (Mäser et al., 2001; Amrutha et al., 2007). Phylogenetic analyses indicate that four groups can be distinguished in the plant KUP/HAK/KT family (Bañuelos et al., 2002).
