Figure 2.

Phylogenetic comparison of ice plant MKT1, MKT2, and KMT1 deduced amino acid sequences with sequences of other plant potassium channel proteins. The phylogenetic tree, including bootstrap values, was constructed using Clustal W AKT1,2,3 and KAT1,2—Arabidopsis; SKT1,2,3 and KST1—potato; MKT1,2 and KMT1—common ice plant (Mkt1, accession no. AF267753; Mkt2, accession no. AF267755; and Kmt1, accession no. AF267754). TaAKT1—wheat; ZMK1—Zea mays. KAT2, SKT3, MKT2, and KMT1 are partial sequences.
