Glucose and salt sensitivity of RAP2.4L overexpression lines. (A) Growth of RAP2.4L OX lines. Plants were grown in soil for five weeks. The left panel shows the RAP2.4L expression levels in the transgenic lines (#43 and #60) determined by Northern analysis. (B) Plants grown in the presence of 3% or 4% glucose for 13 days. R, RAP2.4. RL, RAP2.4L. The numbers indicate line numbers. (C) Glucose dose response of RAP2.4L OX lines. (D) Glucose dose response of RAP2.4 OX lines. (E) Plants grown in the presence of salt for 13 days. (F) Salt dose response of RAP2.4L OX lines. (G) Salt dose response of RAP2.4 OX lines. In (C), (D), (F) and (G), experiments were conducted in triplicates (n = 45 each), and the small bars indicate the standard errors.
