Constitutively expressing TaBASS2 enhances the salinity tolerance in Arabidopsis. a-d The wild-type seedlings and two 35S::TaBASS2 transgenic lines (OE1 and OE3) after a ten-day treatment with 0, 50, 100 or 125 mM NaCl. Bar = 1 cm. e Relative root growth of the wild-type and OE plants treated with 0, 50, 100 or 125 mM NaCl. f The four-week-old soil-grown wild-type and OE plants 0, 10 and 14 days after NaCl treatment. g Plant survival rates measured at 14 day after NaCl treatment. Error bars in (e, g) represent the standard errors (n = 3), with each replicate comprising at least 30 plants. Columns labeled with an asterisk indicate means differing significantly from the WT result (P < 0.05, t-test)
