Constitutively expressing TaBASS2 represses ABI4 expression. a, b The expression levels of ABI4 and HKT1;1 in 12-day-old wild-type and two 35S::TaBASS2 transgenic lines (OE1 and OE3). Error bars represent the standard errors (n = 3), with each replicate comprising at least 12 plants. The expression levels were determined by RT-qPCR using AtACT2 in Arabidopsis as the internal control c, d The Na⁺ contents in the shoot and root tissue from ten-day-old wild-type and OE lines. Error bars represent the standard errors (n = 3), with each replicate comprising at least 200 plants. Columns labeled with an asterisk indicate means differing significantly from the WT result (P < 0.05, t-test)
