Structural analysis of SpSOS1 and SpAHA1 proteins.
(A) Phylogenetic tree of plasma membrane Na+/H+ antiporters from plants. SpSOS1 (JX674067), AtSOS1 (NM_126259), OsSOS1 (AY785147), PtSOS1 (XM_002315801), TaSOS1 (FN356232) and ThSOS1 (EF207775) indicate Na+/H+ antiporters from Sesuvium portulacastrum, Arabidopsis thaliana, Oryza sativa, Populus trichocarpa, Triticum aestivum and Thellungiella halophila, respectively. (B) Phylogenetic tree of plasma membrane H+-ATPases from plants. SpAHA1 (JX628604) indicates Sesuvium portulacastrum H+-ATPase. AtAHA1 (NM_127453), AtAHA2 (NM_001203941), AtAHA3 (NM_001203630), AtAHA4 (NM_114664), AtAHA5 (NM_128013), AtAHA6 (NM_126721), AtAHA7 (NM_115897), AtAHA8 (NM_114131), AtAHA9 (NM_001198521), AtAHA10 (NM_101587), and AtAHA11 (NM_125662) indicate Arabidopsis thaliana H+-ATPases. The phylogenetic trees were constructed using the MEGA5.0 software based on multiple alignments of full-length protein sequences. Evolutionary distances were computed using the neighbor joining method. Bootstrap values are indicated at the nodes of the tree and are expressed as percentages.
