Fig 1. C. australis seedlings are highly insensitive to ABA.
C. australis and tomato seeds were germinated on ½ MS plates, and when seedlings grew to 1 cm in length, they were transferred to liquid ½ MS medium containing different concentrations of ABA to grow for 5 more days. (A) A photograph of tomato (top) and C. australis seedlings (bottom) (Scale bar = 1cm). (B) The lengths of tomato hypocotyls and C. australis seedlings relative to those of the controls (without ABA). Results are presented as the mean ± SE (N = 10). Asterisks indicate significant differences between the respective control and treated groups determined by Student’s t-test (***, P < 0.001).
