AtSPT4-2 improves seed germination and seedling survival under salt stress. a-b Germination rate. The seeds of wild-type (WT), knockout mutants (atspt4-2-1 and atspt4-2-2), and overexpression lines (OE7 and OE10) were germinated on MS medium without (a) or with 150 mM NaCl (b) for 5 days, and the germination rate was calculated at the indicated time points. Values are the mean ± SD (n = 4 replicates, 40 seeds per replicate). Different letters indicate significant differences by one-way ANOVA (P < 0.05). c-d Seedling survival. The seeds of WT, atspt4-2-1, atspt4-2-2, OE7 and OE10 were germinated and grown horizontally on MS medium with or without 220 mM NaCl for 7 days. Photographs were taken (c), and the survival rate was calculated at day 7 (d). Values are the mean ± SD (n = 4 replicates, 40 seeds per replicate). Different letters indicate significant differences by one-way ANOVA (P < 0.05)
