From: Transcription elongation factor AtSPT4-2 positively modulates salt tolerance in Arabidopsis thaliana
AtSPT4-2 enhances the salt tolerance of soil-grown plants. a-b Seeds of wild-type (WT), knockout mutants (atspt4-2-1 and atspt4-2-2), and overexpression lines (OE7 and OE10) were germinated on normal MS medium and allowed to grow for 7 days on MS medium. The seedlings were transferred to soil pots and grown for 3 weeks. Three-week-old plants were irrigated once with or without 250 mM NaCl, allowed to grow for 1 week, reirrigated once with only water and allowed to grow for another 5 days. After 12 days of treatment, photographs were taken (a), and the survival rate was calculated (b). Values are the mean ± SD (n = 3 replicates, 30 pots per replicate, 6 plants per pot). Different letters indicate significant differences by one-way ANOVA (P < 0.05)
