Constitutively expressing the TaAOC1 enhanced the salinity tolerance in Arabidopsis adult plants. A, Phenotype of 4-week-old VC and two transgenic lines (OE1 and OE2) at 0, 7, and 14 d after NaCl treatment. B, The expression levels of TaAOC1 relative to the internal control gene AtUBIQUITIN10 (AtUBQ10) in VC, OE1, and OE2 plants determined by qPCR. C, Survival rates of 4-week-old VC, OE1, and OE2 plants at 14 d after NaCl treatment. Data in B and C are presented as means ± sd, and columns marked with asterisks indicate significant differences from the VC line using Student’s t test (P < 0.05). Error bars represent the sd from three biological replicates. Each replicate contained at least 30 plants. [See online article for color version of this figure.]
