Salt tolerance and RAS1 sequence polymorphism of Arabidopsis accessions from Tadjikistan. (A) Germination and early seedling growth of the Tadjikistan accessions as compared with Ler. Seeds were sown on MS medium or MS medium supplemented with 120 mM NaCl and allowed to grow for 2 weeks. The Arabidopsis Biological Resource Center seed stock numbers for Kondara, Hodja, Sorbo, and Dzi-1 are CS916, CS922, CS931, and CS28980, respectively. (B) Alignment of RAS1 amino acid sequences from the Tadjikistan accessions and Ler. The two residues with polymorphisms are colored in red.
