(a) Schematic diagram showing the transmembrane domains and cyclic nucleotide-binding domain. N and C indicates N-terminal and C-terminal end of the SbSOS1, respectively. (b) The phylogenetic relationship of SbSOS1 with SOS1 from other plant species. The phylogenetic tree was constructed using MEGA ver. 4.0 and the bootstrap values were calculated from 100 replicates and are shown next to branches. The higher bootstrap value signifies resilience in the phylogenetic position of the protein. The scale bar indicates substitutions per site. The protein sequences used for construction of the phylogenetic tree are as follows: Suaeda japonica (BAE95196.1), Chenopodium quinoa (ACN66494.1), Mesembryanthemum crystallinum (ABN04858.1), Limonium gmelinii (ACF05808.1), Ricinus communis (XP_002521897.1), Populus trichocarpa (XP_002315837.1), Vitis vinifera (ACY03274.1), Populus euphratica (ABF60872.1), Zygophyllum xanthoxylum (ACZ57357.1), Solanum lycopersicum (BAL04564.1), Cymodocea nodosa (CAD20320.1), Phragmites australis (BAF41924.1), Oryza sativa Japonica (AAW33875.1), Triticum turgidum (ACB47885.1), Puccinellia tenuiflora (BAK23260.1), Triticum aestivum (CAX83738.1), Brassica napus (ACA50526.1), Lolium perenne (AAY42598.1), Arabidopsis thaliana (AF256224.1), Physcomitrella patens (CAM96566.1) and Thellungiella halophila (BAJ34642.1).
