Fig. S1 Phylogenetic tree of S-RBPs. The phylogenetic tree was made by ClastalW2 Phylogeny using default parameters.
Fig. S2
Fig. S2 Salt stress response of S-RBP11 RNAi transgenic plants. (a) Schematic map of RNAi vector for the suppression of S-RBP11 and expression analysis of S-RBP11 in T1 RNAi lines. GAPc was used as an internal control. (b) and (c) Responses of WT and S-RBP11 RNAi T2 seedlings to 0, 130, or 140 mM NaCl. In (c), error bars represent standard deviation (n = 24 plants).
Fig. S3
Fig. S3 Expression analysis of S-RBP11 under abiotic stresses using semi-quantitative RT-PCR. (a) Expression of S-RBP11 under 300 mM NaCl treatment for 0, 1, 2, 4, or 8 h. (b) Expression of S-RBP11 under cold treatment for 0, 1, 6, 12, or 24 h. (c) Expression of S-RBP11 under 10 μM treatment for 0, 1, 2, 4, or 8 h. In (a) to (c), GAPc was used as an internal control. Similar results were obtained from at least two biological replicates, with one shown here.
